Faculty Faculty of Electrical Engineering Scientific research report Introduction This report describes the scientific research that has been carried out in the period ]994-1998 at the Faculty ofelectrical Engineering from the Eindhoven University of Technology - TUE. Sections A and B as well as the numerical data (tables 5, 6, and 7) and the lists ofresearch output (sections 14 through 17) in Section C have been produced centrally. Tables 5 and 7 have been generated as follows: 1. For every year and for each rank of academic staff, the total input for research, education, and management and other tasks has been taken as the starting point. 2. For each academic rank, a standardised amount of research input was assigned as agreed upon in the discipline protocol: professors 40%, associate professors and other senior staff 60%, and postdoctoral fellows and junior staff 80%. 3. A fixed amount of the total input, 12.5%, was assigned to management and other tasks. 4. The remaining amount, which represents the personnel capacity for education, was compared to the actual annual educational input determined according to the faculty standards. On the faculty level - but not on each research programme level! - there appeared to be an almost perfect match between the actual educational input and the educational capacity. 5. Finally, for each research programme the educational capacity was substituted by the actual educational input, and, ifnecessary, the 1G research input was changed accordingly. Table 6 and the listsofresearch outputhave been compiled from the Annual Scientific Research Reports. The faculty's Standing Committee for Scientific Research, VCW, whose main task it is to evaluate the faculty research annually, is responsible for the correct ranking ofthe research output into the appropriate categories. In order to have Section C as uniform as possible, the written contributions prepared by each research group were collected and discussed intensively in two VCW meetings, during which the VCW formulated a list with directives and suggestions for improvement. This list was fed back to each programme director, who then had the opportunity to revise the written material for his research programme. Anyway, each programme director is responsible for the final version of sections 8 through 13 of his programme documentation. The VCW has advised the programme leaders to mention under section 12, "Other indicators ofquality and reputation," only those tasks that do not belong to the regular academic activities. Hence, the following items have not been included: member of programme committees, member of thesis defense committees, project leader ofnational projects, examiner at national or international universities, referee or review work, invited talks, management functions. On the other hand, in addition to the items mentioned in the Protocol 1998 - honorary doctorates, international awards, guest professorships, editorship of learned journals, membership of international editorial committees - the following items have been reported under section 12, as well: chairman of important international conferences, project leader ofimportant international projects, number ofinvited papers, invited visiting scientist, membership of scientific councils or advisory boards. The faculty regrets that the Protocol did not allow us to present a list ofprofessional publications and that the item "Realized designs," which was included in the previous assessment, was not a valid category in the present assessment. Consequently, important professional publications and realized designs apparatus, instruments, devices, integrated circuits, sensors, software products, machines, testing and measuring set-ups, etc. - could not be reported properly. Introduction 5

Faculty Faculty of Electrical Engineering Scientific research report Section A: Research profile of the faculty Mission statement The Faculty of Electrical Engineering shares the mission of Eindhoven University of Technology with the addition of the following further specifications: The Faculty carries out high-quality scientific activities meeting international standards and providing relevance to society. The Faculty considers itself to be a guardian of the scientific intellectual inheritance of its field ofinterest. The scientific training in Electrical EngIneering and Information Technology, the two-year training in Technological Design, and the Ph.D. degree courses require both education and research; education and research are equally important and strongly linked to each other. Within the study programmes mentioned, knowledge, insight, and skill can be obtained in all main aspects of Electrical Engineering and Information Technology. The Faculty promotes a balanced selection of education and research, and an equilibrium between fundamental and applied scientific research. In both research as well as education, integration and application ofknowledge plays a significant role. Long-term developments and social issues, as well as many industrial problems and transfer of knowledge to major industry and smaller companies require a multi-disciplinary approach. The Faculty is focusing strong attention on these aspects. Key research themes The faculty's research is grouped around four main themes (see also Section B 2): Information and Communication Systems (s], 5, and 12), Telecommunication Technology and Electromagnetics (s 2, 3, 4, and 8), Measurement and Control Systems (s 9, 10, 11, and 13), and Electrical Power Engineering (s 6 and 7). In co-ordination with other Dutch universities, and in line with the university's main focus on information and communications systems, emphasis has been placed on areas in systems design, micro-electronic (III-V) technology, opto-electronics and optical fibres, medical systems, mobile communication, indoor communication, antenna design, power-electronics, micro-drives, model-based control, and power distribution. In accordance with an agreement between the Faculties of Electrical Engineering in Delft and Eindhoven, the research effort on electrical energy systems was decreased, while that on III-V technology and opto-electronics and optical fibres was increased. In several research schools participating researchers seek for the optimum distribution ofresearch themes to the individual research groups. National and international co-operation Numerous national and international co-operations exist with other universities and research centres, and with industrial laboratories. The faculty participates in councils and working groups, networks, and projects involving partners from all over the world. The faculty contributed to a large number of projects of EU-programmes like ACTS APEX, ACTS BLISS, ACTS FLEXIMACS, ACTS MEDIAN, ACTS UPGRADE, BRITE-EURAM, BlaMED, several COST projects, ESPRIT, apex, and RACE. Within the national scope, the faculty participated in several lops, NWO councils, the Energy Academy, and ProRISC (which co-ordinates and supports research in the area of Systems Design and Signal Research profile 7

Faculty Faculty of Electrical Engineering Scientific research report Processing). Most co-operations are at the level ofjoint research projects or the exchange ofknowledge and experience, and are not mentioned explicitly in this document. The following co-operations should be mentioned in particular: COBRA - Communication Technology: Basic Research and Applications, a research school in which many research groups participate and for which the faculty is commissioner; NRC Photonics, one ofthe Dutch top research schools, in which the faculty participates strongly through its participation in COBRA; EIDMA - Euler Institute for Discrete Mathematics and its Applications, a research school with participation of the Radiocommunication group; DISC - Dutch Research Institute for Systems and Control, a research school with participation of the Measurement and Control group; CPS - Centre for Plasma Physics and Radiation Technology, a research school with participation of the High-Voltage Engineering and Electromagnetic Compatibility group; EESI - Eindhoven Embedded Systems Institute, a recently established research institute with participation of the Faculties of Electrical Engineering and of Mathematics and Computing Science. Infrastructural resources The faculty has a number of high-quality research installations of significant value (also in financial terms!) at its disposal. Among those, the III-V laboratory, the computer infrastructure for design, the mm-wave laboratories, the utilities for measurement at plasmas and high-precision measurements in electrical fields, and the laboratory for electromechanics and power electronics should be mentioned in particular. In the near future the research groups participating in COBRA and NRC Photonics will benefit from the cieanroom facilities that are going to be realised on the university campus. Recent reorganisations During the assessment period, the number of chairs has been reduced from 15 to 11. In the 1996 reorganisation, the chairs on Information and Communication Theory and on Electrical Materials were discontinued, and the two research groups were merged with the Radiocommunication and the Electronic Circuit Design group, respectively; at the same time, part of the Electronic Circuit Design group was moved to the Signal Processing group. In 1998 the chair on Electrical Energy Systems became vacant; it had already been decided not to fill the vacancy immediately and to merge the research group with the High-Voltage Engineering and Electromagnetic Compatibility group. Finally, the process ofmerging the chairs on Medical Electrical Engineering and on Signal Processing started at the end of 1998. The 13 research programmes in this report reflect the situation after the 1996 reorganisation. Financial flexibility permitting new research policy The scientific staff had to be reduced in number in recent years, due to cut backs of the governmental finances. Funds were allocated dynamically to the chairs on the basis of commitments in education; in addition, a fixed amount was supplied for research. From its direct income the faculty has committed the equivalent of25 Ph.D. students to support research, and a number ofph.d. grants from external sources have been acquired. The faculty is proud to have achieved - in spite ofthe reduction in research input - a substantial increase ofresearch output in almost all categories compared to the assessment period 1989 1993. 8 Research profile

Faculty Faculty of Electrical Engineering Scientific research report Although the recent reorganisations were initiated by reduction in direct funding, they forced the faculty to focus on a select number of research areas, to look for better co-operations inside and outside the faculty, and to find more multidisciplinary-oriented research themes. The faculty strongly participates in the Research School COBRA and the National Research Combination Photonics, in which new research themes - with corresponding funds - can be found. The same holds for the faculty's participation in the Eindhoven Embedded Systems Institute, and also for the increasing participation in the recently established Faculty of Biomedical Technology. Through its participation in the following programmes of the Stan Ackermans Institute - Centre for Technological Design: information and communication technology, mechatronic design, computer-aided design and manufacture of discrete products, and physical instrumentation, the faculty has strong ties with a wealth of small and large companies. Industry and research institutes show an increasing interest in collaboration with the Faculty of Electrical Engineering. The appointment of highly-qualified part-time professors financed by industry, the foundation of research laboratories on the university campus, and Philips' plans to strengthen its technological and professional activities in Eindhoven by creating a Technology Campus, are just a few examples of new possibilities for the faculty to find research partners to co-operate with. Research policy development and quality control Research policy development and quality control is conducted at two levels: at the level of the research programmes - usually a chair - and at the faculty level. Individual research groups are responsible for developing new ideas, submitting research proposals, seeking external funding, developing and implementing a publication policy, and setting the research standards. They do so in agreement with the scientific director of any Research Schools in which they participate. Formally, the programme director evaluates each ofhis group members annually, and together they set goals for the next year. The Faculty Board and the programme directors meet on a regular basis to discuss the faculty's longterm research policy, and to try and find common topics for collaboration between the different research groups and with research groups outside the faculty. At the faculty level the Standing Committee for Scientific Research, VCW, plays an active role in monitoring research programmes and projects. Each year the VCW compiles a Scientific Research Report in which the ongoing research programmes are described. For each programme both a short review of the past year - along with a description of research input, acquired external funding, co-operations, and a categorized list of scientific output - and short-term plans for the following year are presented by the individual research groups. Each programme is evaluated following a procedure that is similar to the procedure of the five-year assessment, and the same four aspects of academic quality, academic productivity, relevance, and long-term viability of the research programme are taken into account. In its assessment, the VCW relates the results in the past and the short-term plans for the future to the research group's long-term vision, in which the group describes such things as the coherence ofthe programme, the programme's position in the spectrum fundamentalapplication-oriented - development, the programme's position in national and international perspective, the link between the research programme and education, and the group's publication policy with a list of the three most relevant refereed journals and international conferences. A discussion between the VCW Research profile 9

Faculty Faculty of Electrical Engineering Scientific research report and each individual programme director is an essential part of the evaluation procedure; a substantial part of this discussion is devoted to the progress of the Ph.D. projects that participate in the research programme. The committee's conclusions are published in a Research Evaluation Report, which is presented to the faculty community during an official presentation. One of the other tasks of the vew is to advise the Faculty Board with respect to the quality of Ph.D. and PostDoc research proposals that will be directly funded by the faculty. Finally, the committee advises the Faculty Board with respect to the long-term research policy. Future developments It is expected that the reduction of direct governmental finances will continue during the coming years. The Faculty Board is in the process of developing a new procedure through which these direct finances should be distributed over the research groups. The new procedure explicitly uses the realized scientific output and the evaluation results as a means to differentiate in the funding between the different research groups. Furthermore, part of the direct budget will be appointed to groups that need or deserve special financing for research. In line with the above, the faculty's strategy is to allocate tasks among faculty members and research groups to strengthen groups with a strong past performance, to provide necessary investments to start promising new research projects, to stimulate publication in international leading journals and conference proceedings, to encourage applications for grants by making available additional funding to successful groups, to stimulate both fundamental and applied research projects, to stimulate international contacts and joint research, to enhance the impact ofthe faculty's research results in industry, industry-related institutes and research institutions. The faculty is going to redesign its educational programme in the next two years. The aim is to design a modem, consistent curriculum in which the university's concept ofproject-oriented and problem-driven education, the novel aspects ofinformation and communication technology, and the possibilities offered by the university's note book project are implemented. 10 Research profile

The programme encompasses research on fundamental problems in the design and implementation of computer and communication systems and the validation of research results in industrial design. These systems can be real-time systems, distributed systems, embedded systems, multimedia systems or telecommunication networks. They perform many concurrent tasks in a real-time environment such as COllecting, storing, processing, transporting, routing and presenting information. The development of supporting design techniques does not keep pace with the growth of complexity of such systems. New techniques must be developed that enable design on a new higher level ofabstraction. Exploration of analysis and design methodologies for such systems requires a broad knowledge of paradigms, conceptual solutions, architectures and design techniques on various levels of abstraction between specification and implementation. The focus of the research is on design methodology and design tools. This is a common factor in a variety of strongly interacting fields that are explored simultaneously, such as requirements analysis, formal behaviour description, system-level synthesis, optimisation, simulation, testing, verification and validation. Methodology research is performed based on activities in the fields of processor architecture, (real-time) operating systems, communication protocols and communication switches. Research results lone joint proceedings contribution with programme 3. Radiocommunication documentation 19

director Information Processing Systems and Networks Prof.ir. M.P.J. Stevens EB 1 EB are validated for their industrial applicability to design of new processor architectures, distributed computer systems in embedded applications, control applications, and telecommunication networks. 8.1. Design methodology Research focuses on formal system-level modelling techniques for mixed HW/SW systems. Automation and verification for current design complexity conflicts with computability. This project delivers methods for the creation of formal, executable behaviour specifications that allow system properties to be analysed, simulated, validated and verified. Results can be used for the improvement of industrial system-level design of complex systems. 8.2. Design and optimisation of digital circuits Research focuses on theory and tools for modelling, analysis, synthesis and optimisation of digital circuits. Decomposition, quality-driven design methodologies, graph and diagram based methods, and design-space exploration methods can be used to design and implement systems in ASICs, (C)PLDs and FPGAs. 8.3. Architecture and design of processors and computer networks Research focuses on architecture design methods and tools for register transfer and algorithmic behaviour level. The goal is development of interactive modelling, verification, and conversion tools to commercial hardware synthesis tools. Results can be used for system studies and automatic synthesis. 8.4. Tele/data communication, exchanges and networks Research aims at modelling, simulation, and verification of communication interfaces and protocols. Topics are standardisation, performance analysis, queuing and blocking problems. Results can be used for design of telecommunication systems and for distributed embedded systems.

Overview of academic results 9.1. Design methodology The development of languages and supporting tools is the base for system-level modelling of mixed HW/SW systems. A powerful formal specification language (POOSL) has been developed that can describe complex systems in terms of concurrently behaving objects communicating by passing messages. A modelling and simulation tool (SHESIM) has been developed allowing system properties to be analysed, simulated, validated and verified before this system is actually being realised. Design errors can be detected in an early phase preventing design iterations. The project integrates the exploration of specification and design languages, design language concepts, computational paradigms, 20 documentation

director Information Processing Systems and Networks Prof.ir. M.PJ. Stevens EB transformational design, real-time and distributed computing, operating systems and object-oriented programming. 1 EB Methods and tools for system-level performance evaluation have been implemented to compare system architectures allowing retrieval of performance metrics (e.g. throughput of communication channels or the average amount ofmessages in a buffer). POOSL has been extended with probabilisticdata objects enabling the description of stochastic behaviour. SHESIM has been extended with the capabilities to analyse stochastically, the mean interarrival times of messages on communication channels. System-level software synthesis focuses on creation of software for embedded, general purpose, processors, starting from a system-level specification in POOSL. The synthesised software should meet real-time constraints, handle distributed communication, and perform real-time garbage collection. It willallowfaster performanceevaluation and helpquickerformal verification ofspecifications. Software synthesis is split in synthesising the distributed processes (scheduling), synthesising data used by the processes, and garbage collection. Real-time garbage collection (Mark-sweeplReference counting) is available. The synthesis method is based on process execution trees has been completed. Generated software acts in close conjunction with hardware originating from the same system-level specification. The object-oriented method (SHE) and tools for analysis and specification aim at development of distributed real-time HW/SW systems. Together with system-level design approaches, consistent analysis methods prepare all information necessary for formal behaviour description on system-level. Research on concepts for object-oriented analysis uses meta-modelling techniques helping to specify tools for visualising analysis concepts. Formal verification ofthe correctness ofa candidate design is checking the design to formally specified requirements. Research concerns the correctness of the design trajectory, from abstract model to concrete realisation. Current verification activities aim at the integration of techniques and tools for state-space exploration into the SHE methodology. SHESIM has been extended with the ability to verify correctness properties during simulation (checking larger systems non-exhaustive). An algorithm translates properties, expressed in the logic Linear Temporal Logic into finite state automata that can be used as monitors during system simulationsallowing automatic validation ofthe correctness ofcomplex systems. Work has been done on the construction of timed automata that can serve as monitors suitable for the verification ofreal-time systems. It is being investigated how SHESIM can be coupled to existing exhaustive model checkers (e.g. SPIN). Another line focuses verification of real-time properties and the use of abstraction techniques. Testing and debugging HW/SW systems is constrained by internal system operations (event ordering, interleaved process execution, timing dependencies and non-determinism) that are difficult to observe and control. A test & debug method has been developed that improves the controllability and observability of internal system behaviour. The goal is to verify the system's behaviour of an implementation conforms the specification. Our method concentrates on non reproducible faulty communication and synchronisation protocols, faulty mutual exclusive access to shared data or resources, faulty process scheduling, deadlocks, race conditions and faulty interrupt handling. A generic architecture model for systems (consisting of application software, system software, hardware nucleus, applications-specific hardware and communication interfaces) has been defined, providing visibility into the communication of the architecture model and the state information of software processes and hardware components. The key element ofthe method is the insertion ofpcos in a system specification. A formal analysis method on the interference of PCOs has been developed using process algebra. The Interactive Design and Simulation System project focuses on methods and tools increasing ASIC designer's productivity. The design tool IDaSS supporting register level and algorithmic level design documentation 21

--~-~------------ University Information Processing Systems and Networks director Prof.ir. M.P.I. Stevens EB 1 EB and simulation has been created. By integrating design and simulation a designer gets instant feedback on design decisions. The approach helps the designer by automating conversions between design tools with 'expert system'-like rule-bases. The rule-bases that are used to automatically generate synthesisable descriptions of register level designs have been refined. Research on CAD frameworks resulted in support for three design management sub-activities: design data, design tool, and design flow management. The design management component of a CAD framework is a dynamic system that is updated regularly, for instance by the addition of new tools or design flows. The result of this project is a detailed CAD framework model that can be used to reason about CAD frameworks and can serve as a guideline for the implementation ofsuch systems. The model is used to show how aspects like framework completeness can be implemented. Support is provided to design management system developers to handle their data, tools and flows. 9.2. Design and optimisation of digital circuits Research on quality-driven design for digital circuits resulted in: a new definition of quality, a new paradigm of quality-driven design, a methodology for quality-driven design space exploration, and an analysis of some implications of the quality-driven design for design modelling, design languages, design reuse, and (semi-) automatic design methods and tools. The project on generaldecomposition ofdiscrete (binary andmultiple-valued) relations,functions and sequential machines aims at the development of general decomposition theory, methods and prototype tools for logic synthesis. It resulted in a theory for general decomposition, information relationships and measures, and a decomposition methodology and the decomposition tool DEMAIN. A developing method for near optimal state-assignment oflarge sequential machines improves the circuit's parameters as area, speed etc. Commercially tools are targeted to two-level logic. We target to obtain a decompositional state-assignment method targeted to multiple-level logic. The decomposition and synthesis ofmultiple-output combinatorial circuit project develops methods and tools for general (functional) decomposition of (binary and multiple valued) relations and functions into multiple-output combinatorial circuits. A tool for FPGAs (LUTSYN) has been developed. A development method and prototype tool for architecture and logic synthesis of the applicationspecific embedded controllers is developed for controllers that must satisfy specific physical requirements (high speed, small dimensions, and high reliability). The results will be applied to programmable logic devices produced in small series. Work on test-pattern generation for combinatorial circuits with use of DC-BDDs (Term Trees) resulted in a TPG-method and a prototype TPG-tool for ANDIEXOR circuits (XTESTPG). 9.3. Architecture and design of processors and computer networks This research project on architecture design focuses on the study and creation of advanced modular processor architectures. Resulting architectures allow industry to utilise the capabilities of modern ASIC design technologies. Several methods to implement multiprocessing (multiple tasks running in parallel) and super scalar processing (multiple instructions per clock cycle), together with the necessary communication and scheduling methods are being investigated. The following architecture studies have been performed: Multiprocessor CAN/CAL Protocol Controller (bit-level communication protocol processor, high-level protocol processor, user application processor, and a set of interconnected re-usable 22 documentation

director Information Processing Systems and Networks Prof.ir. M.PJ. Stevens EB modules) allows modification ofits protocol and/or application processor configuration. Integrated Multiprocessor Architecture (set of general-purpose processors and a set of shared co-processors for handling complex instructions, connected by two communication networks to transfer commands and results between the two sets). RE.A.L. DSP (capable of executing the equivalent of several 'normal' instructions in parallel). Co-Processor Array video processor. This video processor contains a reconfigurable set of special-purpose and general-purpose processing units, interconnected by a high-speed data packet switching network. 1 ED In research on system design philosophiesa VHDL modellingstrategy for parallel processes in hardware has been developed with the capability of performance analysis. A hardware software co-design strategy for implementation of the implementation of high-speed protocol engines has been developed. A study was performed on adaptive main memories. Fundamental gains in memory performance are achieved by studying how memory reference properties of programs match the architectural and technological characteristics of the memory system. A main memory design has been developed with a tighter coupling between software, cache and main memory. It is used to dynamically adapt main memory operations to the memory reference characteristics of programs, and cache controllers. The design is embedded within the concept of an adaptive main memory, which includes the specification of an adjustable address mapping function, definition of the adaptation targets, a set of adaptation algorithms, and models for representing memory access traffic characteristics. In the project data compression in VLSI, a "Lossless data compression integrated circuit" has been developed. Currently a design of the "VLSI implementation of a context tree weighing algorithm in VLSI" is in development in co-operation with the Radiocommunication group of the TUE. Thealgorithms in hardwareproject focuses on hardware implementation structures for computationally complex algorithms with intrinsic parallelism and with operations not available in general-purpose processors. Implementation of such operations in hardware, the usage of the appropriate applicationspecific memory systems and massively parallel processing schemes enable improvement of the computation speed. A re-configurable hardware accelerator for fast computations in multiple-valued logic and software for automated synthesis of interleaved memory systems have been implemented. The automatic analysis, synthesis and selection of design-alternatives project aims at developing of methods for an effective (semi-) automatic design space exploration, i.e. modelling, construction, analysis and selection of design alternatives. At the system-level it is a practical approach for HW/SW co-design. A prototype interactive HW/SW co-design tool (InCo) has been developed and implemented. 9.4. Tele/data communication, exchanges and networks The protocol verification project aims at research on formal specification and verification. Transport continuity by protection switching for SDH was modelled. A formal POOSL system model enabled successful verification. Eight different fundamental problems could be observed, among which a deadlock problem and faults in the ETSI specification of the APS. The results are a working simulation model and proposed solutions for the problems found during the project. An information model has been designed for the management of WDM optical transport networks. Based on this model the communication structure for transport of management and control information has been developed. Besides communication between network elements, communication with a central management system has been described in relation with its use for SDH, PDH, ATM and IP networking. documentation 23

director Information Processing Systems and Networks Prof.ir. M.P.1. Stevens EB 1 EB Result is a management system design for an optical network demonstrator. A related project focussed on a simulation model of a management subsystem for an optical network. It aims at a functional model for the control ofoptical fibre networks that use WDM techniques. There are fundamental shortcomings in the control concepts for co-operating optical devices that form networks. A balanced concept for electrical versus optical treatment and transport ofcontrol data must be developed. Formal specifications in POOSL will be used to verify proposed control concepts. CORBA is a standard for distributed computing based on an object-oriented approach. Complex applications can be build with a distributed object-oriented technology using CORBA. The research aspect was on the combination of proven and new software implementation technologies and let them communicate platform independent via CORBA. The project demonstrated how complex systems can be built using CORBA to couple distributed implementations in both Java and Smalltalk. In the intelligent networks project applicability of the Telecommunications Information Network Architecture model for the implementation of new services has been studied. The client-server relation between the communication network and the control network has been inverted here compared to the classic IN. The TINA-architecture enables fast implementation of services. The absence of standardised API causes encapsulation to be difficult. The development of services by and usage of services from third parties fail in most cases. Simultaneously a study was done to what extent the use of Java will simplify the taking up of new services in IN. The link with the existing IN-system is a limiting factor. Different philosophies about control/management cause problems in this linking field. In a demonstration project on a Multimedia Service on the new TINA platform has been developed to enable fast development and reuse of services for the telecommunication market. Result of the project is a Desktop Presentation Service integrated in Desktop Video Conferencing and a stand-alone version that shows TINA's qualities for rapid service development. A project on Chipcards in Intelligent Network Services has been performed that aims at extension of the IN standard. As a result a demonstrator has been realised. It implements abbreviated dialling service, account card calling service and universal personal telecommunications service. A project on Parallel services for IN with Java has been performed aiming at the use of Java in the environment of the AXE-lO switching machine for INs. So far C++ and Plex were used to implement central services on an AXE-VM platform. Results are a transparent communication between Java-VM and AXE-VM, Java is integrated in IN by development of a service independent building block. At both the IN, and the Java side a standard service creation environment for Java services has been developed. Research was done on the system aspects and architecture and design ofnext generationpacketswitches for ATM networks. Research on switch architectures and performance studies has been continued. Currently we are interested in architecture and performance, and applied SHE as simulation tool for packet switch fabrics. 10. development The research presented here evolved from rather broad in 1994 to focussed in 1999. Initially we explored digital systems and computer communication with a focus on design, architecture, test and optimisation. We felt a strong need for streamlining. Since 1997 this effort became visible. We developed a very successful programme on methodology for complex communication systems. This programme is well balanced now. It combines more fundamental long-term research with applicable strategic research. We managed to take on new staff members with a background in theoretical computer science. This enables co-operation with the Computer Science Department and the Institute for Programming research and Algorithmics. We constrained the rather broad application area. The focus is more on design of communication systems and distributed embedded systems. This enabled a fine integration of our 24 documentation

director Information Processing Systems and Networks Prof.ir. M.PJ. Stevens EB research programme on system level modelling of optical communication systems into COBRA, and of our programme on system level modelling of distributed systems into the recently started EESI. This also reinforces co-operation with preferred industrial partners such as KPN research, Philips research, Lucent technologies, and IBM research. Current various funding proposals are being submitted. They will enforce the staff in precisely the defined research line. The realised streamlining so far permits to continue most ofthe current research. There is already a strong interaction between the various programs. Research on formal methods and system level design methodology for communication systems will be further intensified at the expense of circuit level research design. 1 EB 11. Societal/technological relevance In the past decade the use ofinformation and communication systems has been increased tremendously. Examples are data and telecommunication systems, signal and image processing systems, multimedia systems and medical systems. These systems can be found anywhere in society in aerospace and automotive industries, measurement and control applications, mechatronics, and in home equipment. The total global market for information and communication technology had a turnover of 1940 billion US$ in 1995. Such information and communication systems are hybrid systems implemented with digital or analogue hardware components, software components, interface technology (sensors and actuators) and communication technology or a mix of these technologies. A lot of these systems control external processes (physical systems) in consumer electronics, copiers, medical equipment, cars, etc. All these systems communicate with the real world of external processes, in most cases using an interface and some form of signal conditioning. Besides the normal control behaviour of a system a lot of extra functionality is implemented for safety reasons, power control, emergencies, communication with an operator or with remote systems, etc. Information and communication systems can be characterised as communicating, reactive, parallel, realtime and distributed systems and extremely complex. The mix of all these characteristics makes the design process of information and communication systems very complex. Until now skilled designers in industry were able (up to a certain level) to develop systems within an acceptable amount of time and reasonable level of quality. In recent years complexity of these systems has grown so fast that system design is only possible with support of scientific methodologies and tools. Besides the growth of complexity there are a lot ofchanges in the design and production process. Examples are Time to market, Time to quality, Cost for error, Product life cycle, Durability, Safety, Availability, Reliability. Most industries have problems with the design and development ofnew information and communication systems caused by control of complexity problems and selection of appropriate implementation technologies. Industry can be helped solving these problems applying scientific methodologies and tools from electronics and computer science to minimise these problems. The research of our group focuses on both fundamental and practical problems like systemlevel modelling, performance studies, formal languages, architectures of computer systems, and communication networks. The results of the fundamental research are implemented in design tools and practical realisations of systems. The work can be described as multi- and interdisciplinary (mix of electrical engineering, computer science, mathematics, etc.) The results of research are applied in industry to validate the methodologies and tools. We made a selection for the telecommunication industry based on the complexity of their systems. Our research consists of a balanced mix of fundamental and applied research. documentation 25

At present, the world-wide demand for telecommunication is increasing with a factor 10 each decade, mainly due to the trend towards globalisation and the evolution of the social structure of our society. Developments like the rapid growth of the Internet and the evolution of multimedia services will push up the future demand for network capacity into the Terabit/s (l012 bits/sec) range. Photonics technologies are emerging as the key technology to serve the world wide demand for network capacity by providing techniques to generate, transmit, process and receive data at the Terabit level and most probably well beyond that. In the subscriber area, the diversity of legacy wired networks and newly developed mobile networks will converge into a common platform that will be based on a broadband optical fibre and radio infrastructure. The Electro-Optical Communication group programme focuses on future communication transport network layers based on all-optical network elements. The group pursues three subprogrammes, which provides a balanced selection of research subjects within the architecture levels oftelecommunication systems; the long haul links, the cross-connects and the access networks to the subscribers. These subprogrammes are formed because the three areas require different type of research focus. Subprogramme ], entitled Multi Gbit/s transmission systems, covers key topics in the area long haul links. The challenge in this highest level of telecommunication architecture is how to overcome limitations imposed by the fibre attenuation, non-linearity's and dispersion. Our long-term research emphasises ultrafast and high-throughput photonic concepts to lead the transmission and switching capacity towards the Terabit/s domain. Solitons, optical phase modulation techniques, performance of semiconductor optical amplifiers (SOA) and novel Praseodymium doped fibre amplifiers are selected applied research topics in this area. Subprogramme 2, entitled Optical cross-connects, covers topics in the intermediate levels of the telecommunication architecture. The challenge is to develop telecommunication nodes that have more throughput, are more reliable and have more speed. Our long term research is aimed at the use of Laser Neural Networks (LNN) to realise network nodes that are more suited for high speed and parallel operations. Our applied research topics in this area are focussed on cross talk, network management in the photonic domain, optical transceivers and packaging and pig tailing ofintegrated optical components. documentation 45

director Electro-Optical Communication Prof.ir. G.D. Khoe ECO 2 ECO Subprogramme 3, entitled Local networks, covers specific topics in the access to the subscribers. A main challenge here is the development towards bi-directional broadband access. Ourlong-term research focuses on the use ofhigh bandwidth optical polymer fibres and the concept ofa common platform that is based on optical fibre and radio connections. Our applied research focuses on the Code DivisionMultiple Access (CDMA) spread spectrum technique in the CATV network. It is clear that the ambitious programme can not be executed in isolation. Multi-disciplinary collaboration within the Inter-university Research Institute on Communication Technology: Basic Research and Applications (COBRA) and within the Faculty play an important role. The Electro Optical Communication group co-founded the Eindhoven Embedded Systems Institute (EESI) to enhance joint research with groups that are active in the area of electronics and informatics. The group participates in various programmes on the national and international level. Participation in the Dutch Innovative Research (lop) on Electro-Optics, provides the relevant links to the Dutch industry and participation in a number of EU research programmes and bilateral foreign contracts provides the required international links. In 1998, the COBRA programme for long term research in Photonic Networks has been accepted by the Ministry ofeducation Culture and Science via a selection procedure by NWO (Netherlands Organisation for Scientific Research) and was labelled as "Top Institute Photonics." The project has duration of 10 years. The Electro-Optical Communication group is one of the three prime participants. 9. Overview of academic results Looking back over the past four years, we may conclude that the progress made by the Electro-Optical Communication group is in line with the directions set by the programme. Our results contributed significantly to the developments in long haul links, in cross-connects and in subscriber systems. Evidence of the success are indicated by world records in silica fibre systems and polymer fibre links, realisation of the smallest cross-connect module ever, 92 refereed publications, 18 invited papers and contributions in books, 2 international awards, 2 patents granted, 3 patent applications pending, 4 European ACTS projects and the qualification of national Top-institute. External funding obtained in the period 1994-98 exceeds an amount of 20 Mf, in which 12 Mfis part of the grant that is allocated via the Top-institute. The number of Ph.D. theses in the review period is limited because, as mentioned earlier, the group in its present form was established in 1994. By the end of 1994 or early 1995 Ph.D. projects started. As will be noted below, 5 Ph.D. theses will be completed in 1999. 9.1. Multi GbitJs transmission systems This subprogramme is pursued within the framework of (l a) STW project System performance of 1300 nm Quantum Well Laser diode Amplifiers, (lb) Ph.D. project Optical solitons in fibre optic communication systems supported by Philips Research, (Ic) European ACTS project UPGRADE, High bit-rate 1300 nm upgrade of the European standard single mode network, (ld) Ph.D. project Praseodymium dopedfibre amplifiers, STW project OpticalActive Fibres, and the COBRA Top Institute Photonics project. As mentioned before, the challenge in this highest level of telecommunication architecture is how to overcome limitations imposed by the fibre attenuation, non linearity's and dispersion. The achievements of this subprogramme that are summarised below showed that we are proceeding properly towards high capacity long haul systems. The combination of projects (la), (lb), and (Ic) provided the group the opportunity to carry out this work in the framework ofa STW project that is monitored by the Dutch industry, a project with European partners and ajoint project with a component manufacturer. A record 10 Gbit/s transmission over 420 km 46 documentation

director Electro-Optical Communication Prof.ir. G.D. Khoe ECO at 1310 nm wavelength using a cascade of loin-line SOAs and a record 10 Gbit/s receiver sensitivity of -30.6 dbm at 1316 nm using one SOA preamplifier were obtained by our Ph.D. students. These records form the basis for the UPGRADE project field trial that connects the cities ofmadrid and Lisbon at 10 Gbitls and 2.5 Gbitls, using SOAs at 1300 nm wavelength. In the meantime, the Ph.D. students proceed to 40 Gbitls via two different routes. A 40 Gbitls WDM (wavelength division multiplexing) transmission with four wavelengths at 10 Gbitls each over 80 km has been achieved and a simulation tool for the use of SOAs in WDM systems has been developed. To avoid pattern degradation due to saturation of SOAs, a novel optical Differential Phase Shift Keying system has been developed successfully. The level of 40 Gbitls has also been reached via Optical Time Domain Multiplexing (OTDM). A 40 Gbitls, 200 km system demonstrator operating at 1300 nm is designed and constructed. This system uses a clock recovery and a 40 Gbitls to 10 Gbitls demultiplexer that both fully operate in the optical domain. Furthermore, fully optical signal regeneration was demonstrated at 10 Gbitls. In the preparations towards this 40 Gbit/s system, a record 10 Gbitls soliton transmission at 1310 nm with a transmission length of 437 km was realised. This 40 Gbitls optical time domain result is considered as the most successful workpackage of the UPGRADE project. 2 ECO The 40 Gbit/s system accomplishments form one of the platforms for the program as planned for the Top-institute Photonics. In 1999, Mr. Jennen and Mr. Smets will both defend their Ph.D. thesis. Project (ld) is complementing the work on 1300 nm optical amplifiers. In this case, a novel 1300 nm fibre based amplifier is foreseen, based on GaGeS Praseodymium doped glass. Simulations revealed the combination has potentially a higher gain and a broader gain region compared with current types. It is believed that the Electro-Optical Communication group is in a good position to carry out the plans for the future because of experience in 40 Gbitls systems, in SOAs and in optical fibre amplifiers. 9.2. Optical cross-connects Key opportunities in this area are created by close co-operation with the TUD-COBRA group of Dr. Smit, a leading group in cross-connect Photonic Chips. This subprogramme is pursued via (2a) lop Electro-optics projects Integrated transceiver for a multi-access optical coherent network, Optical Networks and Optical Cross-connect Core Network, (2b) ACTS projects BLISS, Broadband Lightwave Sources and Systems and APEX, Advanced Photonic Experimental X-connect, (2c) a partnership with KPN Research in the area of management, control and cross-talk in optical cross-connects, and in (2d) a Ph.D. project, Neural optical networks supported by Philips Research and the COBRA Top Institute Photonics project. As mentioned before, the challenge is to develop telecommunication nodes that have more throughput, are more reliable and have more speed. The achievements of this subprogramme that are summarised below revealed that we have successfully developed concepts for all optical crossconnects with higher flexibility and speed, proceeds towards integrated versions and contributed to a good understanding of cross-talk. The combination of projects (2a) and (2b) creates a platform for a national co-operation with Dutch universities and an European co-operation with some major telecommunication operators and manufacturers. These broad platforms are necessary because work on optical cross-connects is complex in nature and can not be executed in a meaningful way without the inputs of operators, manufacturers and other universities. Project (2c) is particularly important because the network management issue and can not be investigated without inputs from a network operator. In the platforms, the Electro-Optical Communication group is a major partner that carries out system design, builds a network demonstrator, and tests devices and modules supplied by partners in the network demonstrator. The Electro-Optical Communication group is also a major partner in the packaging and pigtailing of photonic integrated circuits. In APEX, the Electro-Optical Communication group serves as overall technical project leader. documentation 47

director Electro-Optical Communication Prof.ir. G.D. Khoe ECO 2 ECO One major highlight is the accomplishment of a fully packaged and pigtailed InP-based optical crossconnect chip that is presented as the smallest of the world during a major conference and exhibition in Madrid in September 1998. The module operates with four 2.5 Gbit/s WDM signals. Original work in the area of optical cross-talk is carried out by one of our Ph.D. students. A statistical analysis has been made of filtered interferometric cross-talk that is valid for arbitrary values of the laser linewidth, interferometric delay, and electrical filter bandwidth. Also optical network topologies are found that enhances robustness with respect to accumulation ofin-band cross-talk. In 1999, Mr. Tafur-Monroy will finish his Ph.D. work with a thesis. Major parts ofthis thesis have been publishedin journals already. The partnership (2c) with KPN forms a starting point for the work planned for the Top-institute in the area of optical network management. A novel idea for local optical monitoring of WDM signals has been demonstrated and a patent application has been submitted. This invention is interesting for telecom operators all over the world. A first management system for a cross-connected network has been developed. Results of project (2d) also form a basis for work to be carried out in the Top-institute. It has been demonstrated theoretically and experimentally that a laser diode can be used as a Laser Neural Network in future optical cross-connects. This approach is unique for research in the area of crossconnects. In 1999, Mr. Mos will finish his work with a Ph.D. thesis. 9.3. Local networks The Electro-Optical Communication group co-operates with Philips Research, Alcatel SEL in Stuttgart and SIMAC in the area ofhybrid Fibre Coax (HFC) Networks, to create applied research opportunities in this area. Co-operation with industry is essential in this area because ofthe possible implementation in the short term. Opportunities for the long term are created by collaboration with the Japanese Industry and Research Institutes, because of their leading position in the area of Polymer Optical Fibres. This subprogramme is carried out within the framework of (3a) STW-project Upgrade of CATV-networks towards Broadband Communications, (3b) ACTS project FLEXIMA CS, Bit-rate Flexible Code Division Multiplexfor ATM Access, (3c) lop Electro-optics projects Domestic passive optical networks, Graded Index Polymer Optical Fibre based Systems, and Use of GIPOF in optical access and CATV, and (3d) a co-operation contract with Asahi Glass and Keio University, and close co-operation with NEC, Mitsubishi Rayon, Alcatel Bell, Aleatel Alsthom, Plasma Optical Fibre. As mentioned before, a main challenge here is the development towards bi-directional broadband access. The achievements of this subprogramme that are summarised below revealed that we are in a good position to design concepts for the subscriber systems of the future. Research in the area of CDMA (Code Division Multiple Access) spread spectrum transmission for CATV networks was started in project (3a). This STW project is monitored by the industry and CATV operators. Field trial experiments showed the robustness of this technique against narrow band interference, particularly in the upstream channel of the CATV HFC (hybrid fibre coax) network. Two patents have been granted in this area. The successful design and prototypes of the CDMA modules encouraged Alcatel to cooperate in this work. The cooperation with Alcatel was the basis for the start of the European project (3b). A MAC (Medium Access Control) protocol for CDMA HFC systems that providedtheneeded flexibility tosupportconnectionswithdifferentbitrateandqos (QualityofService) is accomplished. A field trial with 300 subscribers is presently in discussion. Long-term research efforts have been focused on systems using high bandwidth polymer optical fibres. These GIPOF (graded index polymer optical fibres) fibres are invented by Professor Koike at Keio University and further developed by Japanese manufacturers. These fibres are much thicker than their glass counterparts, thus reducing handling difficulties and related costs. Contract (3d) provide the Electro-Optical Communication group with a lead in the world. World records are achieved at 2.5 Gbit/s and 5 Gbit/s at wavelengths of 645, 48 documentation

director Electro-Optical Communication Prof.ir. G.D. Khoe ECO 840 and ] 300 nm, over a transmission distance of up to 550 meters. The results are confirmed by a simulation model. Within project (3c), the potentials for these fibres in home and local area environments are investigated. The results obtained with CDMA and GIPOF provides a platform for future research in the area of the subscriber access and local networks. The group participates in EESI (Eindhoven Embedded Systems Institute) to cooperate with other groups that carry out complementary work in home systems. 2 ECO 10. development In ]999 the Top Institute project Photonic Networks will start. The project has a duration of ten years. For the first five years 3.8 Mfl. for personnel, 3.1 Mfl. for materials and 4.3 Mfl. for investments has been assigned to the Electro-Optical Communications chair. Within the framework of this project, the time domain, the wavelength domain as well as network aspects will be further explored. Ultrafast photonic devices will become available and a large number of wavelengths will be used simultaneously in optical networks. There is a need for a novel optical network concept, which can benefit from the new opportunities offered by ultrafast photonic components in the time domain as well as a need for novel photonic signal processing methods, which are more suited to handle a large number of parallel optical signals simultaneously. Also, new concepts are needed to manage the photonic network infrastructure because the physics of optical telecommunication networks differs fundamentally from the physics of electrical telecommunications networks. We will conduct research in the areas ofnetwork nodes, the transmission systems between the nodes and the network management. Within subprogramme 1, we will search for concepts, which translate ultrafast photonic devices into key functions, needed in transport systems such as multiplexing, demultiplexing and regeneration. We plan to explore how the use of harmonics and subharmonics can provide possibilities to manipulate speed and timing. Within subprogramme 2, we consider the Laser Neural Network (LNN) as a key concept for photonic network nodes that can benefit from ultrafast photonics and handle large numbers of parallel operations. Another plan is to investigate how nodes can operate fully in the optical domain as much as possible. We will also study the use of local intelligence for photonic network management to allow monitoring, control and decisions to be performed locally as much as possible. We plan to study whether the local intelligence can make adequate decisions, using a model that contains an accurate physical model and adequate calculating power. We will also investigate how the network management can handle adaptive dispersion management of the fibre links, because dispersion properties may change with routing. Within subprogramme 3 we will investigate in the area ofthe customer premises a 'road map' from present situation with telephones lines and coaxial cable to high performance multi-media networks with polymer and silica optical fibres and wireless connections. This will be proposed in a joint project with our radio communications group. The top institute project opened the opportunity for our group to expand with one assistant professor (realised), one technician (realised), visiting scientists (one realised, Prof. Frietman) and PostDocs. 11. SocietaVtechnological relevance Telecommunications networks are the largest and most complex artificial structures the human race has ever built and have gradually become an essential social and economic infrastructure. The world-wide demand for communication has consistently pushed the transport speed from merely 34 Megabitls in the early eighties to 10 Gigabit per second today, i.e. a growth of a factor 10 each seven years. The growing demand for communication is mainly due to the trend towards globalisation and the evolution of the social structure of our society. Presently, we witness a revolution towards a global information society documentation 49

director Electro-Optical Communication Prof.ir. G.D. Khoe ECO which is most clearly visible by the very rapid introduction ofthe Internet and ofwireless communication equipment. Results or our research contributes to the upgrade of the telecommunications infrastructure that will be needed because of the trends just mentioned. Without the upgrade, communication traffic- 2 jams will occur. ECO The group has worked for the last years as a research team in various programmes on the national and international level. They participate in the Dutch Innovative Research (lop) on Electro Optics, which provides the relevant links to the Dutch industry in this area and also participate in a number of EU research programmes: ACTS BLISS, ACTS UPGRADE, ACTS APEX and ACTS FLEXIMACS. The programme director is member ofinternational professional societies, like IEEE, and the European networks CLUSTER and PHANTOMS. PHANTOMS provide the scientific platform for about 80European research groups from universities and industries. In ]997, the Technology Foundation (STW) together with COBRA has established a national network 'Communication Technologies'. The programme director is member of IEEE/LEOS (Laser and Electro-Optical Society). This society provides an invaluable scientific global network. Finally, an agreement for collaboration and exchange of students and staff between COBRA and the AUSTRALIAN PHOTONICS Network has been arranged. The Electro-Optical Systems Group, the Asahi Glass Company and Professor Yasuhiro Koike, Keio University have an agreement to collaborate in the area of high bit-rate polymer optical fibres. A similar collaboration is ongoing with NEC Research and the Mitsubishi Rayon company. The group is also involved in a joint project with KPN Research including the participation of Professor Leonid Kazovsky ofstanford University. The Electro-Optical Communication group co-founded the Eindhoven Embedded Systems Institute (EESI) to enhance joint research with groups that are active in the area of electronics and informatics. The links of COBRA with industry will continue through the collaborations within the national, European, and international programmes. The Dutch lop Electro-Optics has established strong links between COBRA and the relevant national industries like Philips, KPN, AKZO, Lucent Technologies etc. In the European programmes the partners of COBRA are all the major European industries active in communication technologies. These links are supplemented by the PHANTOMS network, the STW-platform, relations of the individual research groups and also through members of the COBRA Committee and Advisory Committee. 12. Other indicators of quality and reputation General Since its start in 1994, the group has been granted the projects BLISS, UPGRADE, APEX and FLEXIMACS, within the European Commission ACTS. The group has been very successful in receiving grants or support from the Technology Foundation (STW), STWINWO Investment Support, lop, KPN (Dutch PTT), Philips and Alcatel.

The programme aims at achieving a balance, spreading the effort equally, between the study of fundamental aspects of radio transmission and communication and the application of the results in the development of communication and remote sensing systems. The central activity of the programme is the study of the fundamental limitations ofthe transmission of information, in particular over the radio link. With the expertise built up in this field, applications in the area of the design and modelling of mobile communication and remote sensing systems are addressed in cooperation with external organisations. The wideness of the frequency range studied in relation to novel applications (l to 1000 GHz) is an important aspectofthe programme. Cellular systems and mobile satellitecommunication systems favour the use offrequencies in the range 1-3 GHz. The high information transport capacity required nowadays for wireless multimedia communications, however, can only be accommodated in the millimetre wave frequency bands above 10 GHz. Millimetre-wave atmospheric remote sensing uses frequencies up to 1 THz. The antennas, the obstacles on the propagation path, and the constituents of the propagation medium, impose fundamental limitations on the radio link. They are studied in the subprogramme Antennas, propagation and remote sensing. The propagation research is directed towards the study of radiowave propagation on terrestrial and Earth-Space paths, in particular to support the development of new systems such as personal communications and mobile multimedia systems. Wave interaction studies of the atmosphere are also directed towards the application of remote sensing techniques to atmospheric and meteorological research. The radio channel imposes restrictions on the transmission rates and modulation methods that can be used. The subprogramme Digital radio systems studies advanced modulation and transmission schemes in combination with networking techniques. In particular, interworking between the multiple-access radio channel and the fixed network is studied as part of this programme. The first objective ofthe subprogramme Source and channel coding is to establish fundamental limits in transmission and storage of information; the second is to develop efficient methods that approach these limits as closely as possible. The research objective in source coding is to find techniques (codes) that are universal, i.e. achieve a high compaction or compression without knowing the source statistics in advance, and that have a low implementation cost. While in the past, research in channel coding documentation 67

director Radiocommunication Prof.dr.ir. G. Brussaard ECR concentrated on finding the best error-correcting codes for the simplest channels, the objective is now to find codes that allow efficient decoding procedures, often for channels with a more complex structure (such as radio channels). 3 ECR Practically all programmes are supported by international cooperation. The TUE programme of propagation research has a long tradition of playing a leading role in European programmes of cooperation. Examples are the OPEX programme co-ordinated by ESA and TUE and the various COST projects of the European Commission. Research on millimetre-wave indoor networks is carried out within a project (MEDIAN) ofstrong international cooperation between industry and research institutes. The programme is closely coordinated with the other research programmes of the Division Telecommunication Technology and Electromagnetics. Important interfaces exist with the programmes in Electromagnetics and Electro-Optical Communication. The chair Radiocommunication participates in the research Schools EIDMA (coding research) and COBRA (communication systems-oriented research). 9. Overview of academic results 9.1. Antennas, propagation and remote sensing In 1994, a Ph.D. project for the characterisation of the mobile satellite channel was expanded and redirected towards application in a general system planning tool for mobile radio. This redirection has been the start of a very fruitful new line of research. Using high-frequency asymptotic techniques, for a given urban environment (building data base) a fully 3-dimensional ray-tracing method for the propagation path was developed, resulting in accurate predictions of the characteristics of the radio channel in the time and frequency domain. The research was sponsored by the European Space Agency (ESA). The resulting tool was purchased by the International Maritime Satellite Organisation INMARSAT and a user shell was developed by a UK software company under a royalty agreement with TUB. The software was the first truly 3-D implementation in the world. The study was extended to the terrestrial (cellular) mobile environment, in cooperation with KPN. Several measurement campaigns were executed to validate the results, both for satellite and terrestrial applications. The Ph.D. study won the national Veder prize for innovative radio research. The expertise and reputation thus built up in the area ofmobile channel analysis led to further cooperative projects with industry. In cooperation with KPN, an adaptive antenna array system was designed with direction finding and beamforming antennas. The antenna uses the MUSIC algorithm for localisation of the mobiles. A DSP implementation of the control software, proving the feasibility of real-time use of the antenna in GSM, was realised. In a follow-up project sponsored by KPN and Ericsson, with this technique a circular synthetic array antenna was realised which was used in combination with a channel sounder. With this instrument it was possible to measure the time / frequency characteristics of a mobile channel and at the same time measure the spatial distribution of the multipath components in three dimensions. Field tests were carried out in cooperation with Ericsson Mobile Systems, KPN Research and Swisscom. The measurements with this unique diagnostic instrument were able to unveil the shortcomings ofvarious software tools used by these companies. At the same time they indicated the way for further research. A four-year project in the electromagnetic modelling of Fresnel-zone plate antennas (FZPA) was concluded with the publication of a complete set of design parameters for such antennas. FZPA's use a set of metallic or dielectric rings to achieve high gain and find application in satellite broadcasting. The theory developed to design and analyse the FZPA was validated by measurements on frequency-scaled models using the Vector Network Analyser (VNA) at 50 GHz. 68 documentation

director Radiocommunication Prof.dr.ir. G. Brussaard ECR In cooperation with ESA, SRON and the University of Siena a Ph.D. project was carried out for the electromagnetic analysis and subsequent design of miniature lens antennas for use in integrated phased-array structures operating at 300-500 GHz. Such arrays may be applied in limb sounders operating in these frequency bands in earth-observation satellites to observe atmospheric constituent (i.a. pollutants) at high altitudes. Various configurations for the integrated lens antenna were analysed. A software package was developed which allows characterisation ofthe antenna, including the feed and transmission line structures. With his work, the Ph.D. student has won the Bahler prize of the Royal Dutch Institute of Engineers (KJvJ) and the Young Scientist Award of the International Symposium on 3 Antennas and Propagation of Japan. ECR The six-year project of propagation measurements with the millimetre-wave beacons of the Olympus satellite, sponsored by STW, was concluded. The earth station of the chair has been the prime station in the European Project apex for the collection of propagation statistics. Using software developed by ESA and validated by TUE, the results of measurements at 12, 20 and 30 GHz, collected all over Europe, were collated by the apex group. Analysis of the statistical results and further development of relevant propagation models is presently carried out inside a COST project. In a Ph.D. project, the dual-polarisation measurements at all three frequencies carried out by the TUE station have allowed the development of a new model for crosspolarisation due to rain and ice in the Satellite-Earth path. It was shown that it is possible to separate the two depolarisation mechanisms (rain and ice) and obtain physical insightas well as statistical information on their relative contributions. This information is ofimportance for the development of millimetre-wave satellite communication systems. As part of a Ph.D. project, in close cooperation with the International Research Institute IRCTR ofdelft University of Technology (TUD) and the Royal Netherlands Meteorological Office (KNMI) a series of comprehensive experiments were carried out to study the liquid water content and structure of clouds. Radiometric observations at 20, 30, 51, 53 and 55 GHz enable the extraction of information on water vapour and liquid water in the atmosphere through various inversion techniques. With its experience in and equipment for radiometric measurements, the chair contributed to several intensive international measurement campaigns in support of environmental and climatological studies. 9.2. Digital radio systems The research in digital radio systems is focused on high-speed indoor radio networks. Results of extensive channel probing measurements over a 2-GHz wide band at 40 and 60 GHz were used to characterise the indoor radio channel and study basic limitations in transmission speed. A simulation package for indoor propagation was developed as a complement tothese measurements. The package is able to analyse a simulated indoor environment and produce a prediction ofthe channel characteristics., I With this expertise, the chair participated in the ACTS project MEDIAN for the development of a demonstrator for a wireless local-area network (WLAN) operating in the 60 GHz band at 155 Mbit/s. The project is carried out by a large consortium which includes the Dutch research institute TNOIFEL, the German institute IMST, the universities ofdresden and Rome arid large companies such as Motorola, Nokia, VTT, SONY and Dassault. The following three TUB research tasks were completed within the allocated time and budget (kfl 700): 1. Development of antennas for the base station and terminal, including (miniature) rotary joints. Various antenna configurations were tested and a set of hom antennas was finally chosen and delivered for the demonstrator. 2. Full responsibility for the workpackage "Interworking" which included the development ofmac protocols for the seamless interconnection ofthe mobile terminals on one side and the fixed ATM documentation 69

director Radiocommunication Prof.drjr. G. Brussaard ECR network on the other, through the multiple-access radio system, allowing handover between base stations while maintaining full ATM functionality. 3. Integration of the demonstrator in cooperation with TNOIFEL. 3 ECR In addition, a complete system simulator was developed using the OPNET software as a platform. With the MEDIAN system simulator, parameters such as package delay statistics, handover algorithms and throughput can be studied using the full set of protocols. 9.3. Source and channel coding The context-tree weighting (CTW) method, invented in basic form in 1993, was further developed. The CTW algorithm is a universal coding algorithm that provides lowest redundancy for various model classes. It has proved to be world leader in compaction performance. Research in the reporting period concentrated on the analysis and proof of the performance. The paper "The context-tree weighting method: basic properties," published in IEEE Transactions on Information Theory in 1995, received the IEEE Information Society Best Paper Award. In a study carried out for KPN Research, the CTW algorithm was compared with Lempel-Ziv coding, in particular with respect to the trade-off of memory versus compaction rate. Implementation of several modifications to the basic algorithm resulted in reduction of memory requirements without sacrificing compaction performance. Two patent applications containing these modifications were filed. A new switching method was developed, which is able to combine the performance of two separate (universal) source coding algorithms. Out of two algorithms running in parallel on a data sequence, the switch algorithm uses locally the one that is most efficient there. Three different weighting algorithms for the switching method all gave a significant improvement on the two algorithms they combined. One of the algorithms can be the CTW algorithm. Results of research aimed at finding a good companion algorithm for the CTW method were presented at the 19th Symposium on Information Theory in the Benelux in 1998. The paper won the Gauss Foundation Award for the best paperof the conference. In cooperation with Philips Semiconductors and the Division ECS a research project on efficient decoding structures for the Digital Video Broadcasting (DVB) standard resulted in an implementation of an efficient Forward Error Correcting (FEC) unit on silicon. A project was started in 1995 on coding strategies for channels with feedback, where feedback information is used to decrease the complexity in semi-duplex connections (e.g. subscriber loops). Multiple-repetition feedback coding (MRFC) schemes were developed for soft-output discrete memoryless channels (SODMC), that minimise coding complexity as well as the feedback information rate for the additive white Gaussian noise (AWGN) channel. Results were published on the performance of block and recursive coding methods for the new scheme. Three Ph.D. projects were completed in the field of multi-user information theory. In two of these, discrete coding strategies for the binary multiplying two-way channel were investigated; the third study addressed feedback coding strategies. 10. development Development ofthe programme in the next four years will be in accordance with the structure, scope and goals outlined under Section 8 above. A particular feature goal in the coming years will be the integration ofthe research in information and communication theory (which was recently added) in the programme. In this area more emphasis will be placed on novel telecommunications applications of channel and 70 documentation

director Radiocommunication Prof.drjr. G. Brussaard ECR source coding. The current state of knowledge requires that, in the classical areas of Information and Communication Theory, practical algorithms must now be developed. Cross-fertilisation of the applied research in the different disciplines ofthe programme will be a major goal in the coming years. Funding for a new Post-Doc project on application ofthe CTW algorithm in channel decoding structures and for a Ph.D. project on applications of the CTW method was recently awarded by the University Board and STW, respectively. In view ofthe needs ofindustry, channel modelling will be a priority area in the coming two to four years. A new programme ofco-operation with the Canadian national Communications Research Centre (CRC, Ottawa) and IRCTR has been set up, covered by a tri-partite memorandum ofunderstanding, for research on mobile radio channel modelling. Under this programme, regular exchanges of staffand students and collaboration in equipment development and data analysis are taking place. The programme is financed collectively by the three parties, and additional support from STW has been applied for. 3 ECR Research in wireless communication systems and networks will be mainly pursued within larger platforms of co-operation, such as the European MEDIAN consortium. The general experience of the chair in measurements and simulation ofmillimetre-wave systems and the specific knowledge obtained in interworking between mobile and fixed systems will be the input in the planning for new European projects for continuation and expansion of the research in the next three years, which are now in preparation. A joint proposal for the development of a network termination (NT) for all wired and wireless networks inside the subscriber premises is in preparation by the chairs Radiocommunication and Electro-Optical Communication. The maintenance and renewal of (costly) equipment, both for passive remote sensing and for channel sounding is a priority item for next year. Funding will be from the income ofseveral3g contracts carried out in the previous years. The acquisition of funds for further research will be accompanied by efforts to attract scientists from outside to support the work under temporary assignments. The success of this effort so far is illustrated by the arrival, next year, oftwo post-docs. The same applies to the recruitment of postgraduate students which now are at a record number (for our chair) of 7 internal and 2 external Ph.D. students and 2 MTD students ("twaio's"). 11. SocietaVtechnological relevance A special activity in the propagation research programme is the execution, under sponsorship by the EC and the ITU, of experiments of microwave propagation in tropical regions. In these regions there is an urgent need for data and planning tools for satellite communication systems. The expertise built up already in the early 80's in development co-operation projects with universities in Indonesia and Africa enables the chair to be active in transferring knowledge and experience in radio research to developing countries. The results of satellite experiments carried out from 1992 to 1995 in Surabaya, Indonesia, at frequencies above 10 GHz have directed the Indonesian Government to decide to employ new satellite services at these frequencies. In a project executed in Africa, Workshops on modern mobile communications are organised in three different countries. These workshops bring together representatives of telecommunication industries and governments in Central Africa to discuss and harmonise policies regarding new developments. In line with this policy, also supervision of graduation projects carried out by Technology Management students, notably in the area of telecommunications in developing countries is an important activity. Knowledge transfer to industry is an important consideration in the management of the programme. In cooperation with industry and the Foundation for continuing education PATO, courses are organised on documentation 71

director Radiocommunication Prof.drjr. G. Brussaard ECR 3 ECR terrestrial and satellite mobile system design. The courses are also given as in-plantcourses. Cooperation with industry also includes the supervision of Ph.D. projects carried out by industrial R&D staff. The R&D contracts with industry facilitate knowledge transfer, but also feed the research. A good example is the research contract with KPN Research. This research has led to improvements in the network planning tools for the cellular mobile systems ofkpn. It has also led to cooperation between KPN and Swisscom in this area. In tum, this success has resulted in an expansion of this research by the chair, in cooperation with CRC, Canada. Consultancy services are given to small and medium-sized companies, mostly in the area ofmobile communications, e.g. Drager Electronics (wireless data acquisition for medical scanners), MBC Europe (system design and frequency licences for a European mobile datacommunication system), and CallMax (advise on base station design and the utilisation of a satellite system). 12.

For instance, there is a strong demand for semiconductor lasers with high modulation speed (above 100 GHz) for all-optical photonic networks (COBRA NWO-NRC). New device concepts like polarisation-controlled Vertical-Cavity Surface-Emitting Lasers (VCSELs) will be applied for parallel short-distance transmission in optical interconnects. High-power semiconductor lasers are integrated in long-haul optical links; they are also applied in optical printing and medical applications. Highbandwidth, low-noise opto-electronic receivers, monolithically integrated with all-optical photonic ICs are essential to enable the access to Terabit/sec communications' world. Optical Phase-Locked Loops (OPLLs) are essential building blocks in Optical Beam Forming Networks for phased-array radar systems. On the other hand, there is a strong need for microwave X-band high-power amplifiers for radar applications. The Electronic Devices group currently addresses many aspects of the above-mentioned topics in various research projects and/or proposals: Optoelectronics High bit-rate low-chirp GaAs and InP based lasers for high bitrate transmission (a.o. modelocked lasers) Lasers for optical interconnects (VCSELs with polarisation control) High power short-wavelength InGaAs-GaAs lasers as pump lasers for Erbium Doped Fibre Amplifiers (EDFAs) GaN based blue LEDs and lasers GaAs and InP based Opto-Electronic Integrated Circuits (OEICs) for optical Wavelength Division Multiplexing (WDM) receivers and Optical Phase-Locked Loops (OPLLs).

- 1 director Electronic Devices Prof.Dr.-Ing. L.M.F. Kaufmann EEA GaN-based high-power X-band amplifiers. All our research projects contribute to the TUE Inter-University Research Institute on Communication Technology (COBRA). They are complementary with the research programmes of our colleagues in our TUE Division Telecommunication Technology and Electromagnetics, where we are part of, as well as at the Technical Universities of Delft and Twente, and our international neighbours (Aachen, Duisburg, Jiilich, Leuven, Ghent). 4 EEA Research of the Electronic Devices Group is directed towards contributions to the development of materials, components and circuits for (opto-) electronic applications. Modelling, design, preparation, test and evaluation of active and passive III-V compound semiconductor devices is performed for different types of lasers, Opto-Electronic Integrated Circuits (OEICs) and Monolithic Microwave Integrated Circuits (MMICs). The group owns a high-quality (class 100) clean room specialised in device processing of III-V materials, GaAs, InP as well as GaN based. Our research programmes are fundamental, multidisciplinary; physicists, chemists and electrical engineers are group members; collaboration with COBRA-partners is essential. The amount of application oriented projects is expected to increase in the coming two years due to the co-operation with TNO-FEL, The Hague and the Netherlands Foundation for Research in Astronomy (NFRA), Dwingeloo. 9. Overview of academic results 9.1. Components for high.bitrate communication systems GaAs and InP based High Electron Mobility Transistors for microwave and millimetrewave optoelectronic and microwave applications (F Karouta, H.C. Heyker, L.M.F Kaufmann) Research on compound semiconductor based microwave and millimetrewave transistors for Opto Electronic and Monolithic Microwave Integrated Circuits (OBICs and MMICs) leads to the successful realisation of our first generation GaAs based photoreceiver in 1997. Metal-Semiconductor-Metal (MSM) photodetectors were monolithically integrated with Trans-Impedance Amplifiers (TIAs) based on 1 fj.- m gatelength technology. Opto-electronic characterisation ofthe photoreceiver using a modulated semiconductor laser (wavelength 855 nm) in the frequency range 50 MHz - 10 GHz indicates a bandwidth of6 GHz for a transimpedance of400 Ohm, effectively into a 50 Ohm load. The lop Electro Optics supported the project. One of the tools to improve the transimpedance-bandwidth product is to use sub-micron gatelength transistors, which have been demonstrated in 1996 using standard optical photolithography. This shadow mask technique has been applied to GaAs MESFET structures with a gate width of 100 /-Lm and a source drain distance of 3 /-Lm. Results (table) are in agreement with best values reported in literature. gatelength Transconductance F r Fmax 1.0/-Lm 190mS/mm 18GHz 36GHz 0.5/-Lm 290mS/mm 32GHz 55 GHz 0.3fJ.-m 370mS/mm 48GHz 100GHz We intend to apply electron-beam lithography in future. Our goal is sub 0.1 /-Lm gatelength transistor technology for> 100 GHz applications. Since January 1998 we develop Opto-Electronic GaAs MMICs for analogue microwave links in cooperation with TNO-FEL, The Hague. In co-operation with the University of Helsinki we have started a related project in September 1998 to design and realise GaAs based photoreceivers with subrnicron structures. 98 documentation

director Electronic Devices Prof.Dr.-Ing. L.M.F. Kaufmann EEA Indium Phosphide (lnp) based active and passive devices (photodetectors, transistors, photoreceiver, MMICs) are essential for applications at wavelength] 300 nm and 1550 nm as in for instance Wavelength Division Multiplexing (WDM) all-optical photonic networks (COBRA NWO-NRC). Recently we have developed InP based Pseudomorphic High Electron Mobility Transistors (PHEMTs) to be applied in Trans-Impedance Amplifiers (TIAs). The obtained results as the maximum transconductance gm mm; == 380 ms/mm and cut-off frequency it == ] 8.8 GHz are actual state-of-the art for devices with gatelength LG == 1 I-im. The designed bandwidth of the photoreceiver is to be 10 GHz. GaN-based transistorsfor high-power electronics (F. Karouta, L.M.F. Kaufmann) This project aims the development of the technology for GaN based materials for high temperature and high power electronic devices. One of the long-term goals is the development of an X-band power 4 amplifier in collaboration with KU Nijmegen (RIM), TNO-FEL and the Royal Netherlands Navy. Besides Philips Semiconductors and Signaal, Hengelo are interested in the results obtained. The short- EEA term goals are to fabricate and optimise the processing of GaN FETs and HEMTs. In the absence of a decent wet etching process, patterning GaN structures is only possible using plasma etch technique. In 1998 we started our research on Reactive Ion Etching (RIE). Actually smooth surface and reasonably high etch rate can be achieved using MOVPE-grown GaN on sapphire substrates. To the best of our knowledge, we are the first group worldwide who has elucidated the chemical role of Fluorine in conjunction with Chlorine in the etching process. The maximum etch rate we achieved is 430 nm/min which is a world record in conventional parallel plate reactors. This etch process is also used for final treatment prior to the growth by homo-epitaxy of GaN on GaN substrates. This work is going on in collaboration with the group of Prof. Porowski (Unipress, Poland). Several additional collaborations have meanwhile been established: AIXTRON and RWTH Aachen and the University ofghent (INTEC). The results obtained in this project will be applied in a new project on blue emitting LEOs and lasers. Double-Barrier Resonant-Tunneling Devices for digital applications (T. G. van de Roer) The goal of this work is the understanding of the resonant tunneling process by combining classical and quantum-mechanical modelling and by applying this knowledge to practical devices and circuits. Starting in ]989, a model has been developed that enables an accurate calculation of current-voltage and current-capacitance characteristics. Furthermore in the microwave characterisation up to 40 GHz a great expertise has been built up. In 1996 three terminal Double Barrier Resonant Tunneling Device were successfully realised. Recently structures with different AlAs mole fractions in the barriers have been developed and tested. In the EC-ESPRIT programme MEL-ARI we are taking part in a project concerned with the integration of devices like tunnel diodes or DBRT diodes together with Heterojunction Field Effect Transistors for digital integrated circuits with reduced complexity. 9.2. Short-wavelength lasers for special purposes High bit-rate low-chirp GaAs and InP based lasers for high bitrate transmission (T.G. van de Roer, G.A. Acket) The purpose of this project is to realise carrier temperature modulation in a laser by means of a novel vertically integrated transistor-laser structure in which the electrons are injected into the active region of the laser via the emitter-base part of a bipolar transistor. This means that the technology of a laser has to be combined with that of a bipolar transistor. We have analysed the physical model ofcarrier and energy injection in laser devices. Meanwhile, we could solve the transport problem for hot electrons. All the relevant scattering mechanisms as well as non-parabolicity of the multi-valley conduction band are taken into account resulting in an accurate computation of the carrier temperature as a function of the modulating voltage. The first AIGaAs/GaAs three-terminal, bipolar injection, Hot Electron Laser was documentation 99

director Eindhoven University of Technology (TUB) Electronic Devices Prof.Dr.-Ing. L.M.F. Kaufmann ~---------------- EEA designed in 1997. The structure has been grown by MBE at the Physics Faculty (TUB-NV). Processing this structure involves the etching of the layer stack down to two different, very thin (50 nm), contact layers. This requires two different wet chemical etching processes; high selectivity is required. This work is supported by STW. It is done in co-operation with the Research Institute for Materials ofthe Catholic University of Nijmegen. High power short-wavelength InGaAs-GaAs lasers as pump lasers for Erbium Doped Fibre Amplifiers (TG. van de Roer, G.A. Acket) 4 EEA The goal of this work was the development of a high-power laser design based on a low-confinement structure. The ultimate goal is an optical output power of 1 W CW at 980 nm wavelength. Devices have been processed and characterised based on layers grown by the group Semiconductor Physics of TUE, by INTEC, University of Ghent, and by the National University of Australia in Canberra. The maximum output power before Catastrophic Optical Damage (COD) is 1.8 W CW per facet, which means about 35 mwi/lm; world's best results for single devices. For a conventional symmetric structure in the same material system it represents a 2.5 times improvement compared with a COD limit of 14 mwi/lm reported before. Although the range of single lateral mode operation was restricted to 200 mw it shows that the low-confinement principle for high-power operation is successful. Much more insight has been obtained in the operation of high-power lasers by developing and applying a model that not only calculates the optical field profile but also models the transverse and lateral current flow as well as the temperature distribution inside the device. The lop Electro-Optics supports this work. lasersfor optical interconnects (TG. van de Roer, G.A. Acket) The objective of this work is to develop the technology for top-emitting VCSELs on semi-insulating substrate, with an eye on monolithic integration with electronic devices. To achieve this goal intracavity top and bottom contacts were developed, necessitating the etching of a double mesa as well as the selective oxidation of grown-in AlAs layers to a predetermined diameter. In this way a stack of Alo.sGao.5As/AIAs layers can be converted to a stack of Alo.sGao.sAs/Alz03' which is usable for light of 650 nm wavelength, important for future disc readout (DVD) lasers and plastic optical fibre communication networks (GIPOF). Another innovation was the use of an asymmetric contact layout, which leads to lowerthreshold currents and control ofthe polarisation ofthe emitted light. A Netherlands patent has been granted for this invention in 1998. The lop Electro-Optics supports this work. In 1998 a co-operation has been started with the Free University of Brussels and the INTEC Institute of the University of Ghent. 9.3. MOSFET model for analogue circuit design An improved compact circuit-level MOSFET model has been developed which gives accurate results for distortion analysis (i.e. the higher-order derivatives of drain current to all terminal voltages). It incorporates a more accurate description of various physical phenomena such as mobility degradation, gate-voltage dependent series resistance, velocity saturation, channel length modulation, static feedback and self-heating. The model has been implemented in the Philips in-house circuit simulator (Pstar) at Philips Research Laboratories. This project was funded by STW till November 1998. 9.4.

We have been asked by the Netherlands Foundation for Research in Radioastronomy, Dwingeloo, to contribute in the development ofextremely low noise amplifiers for the Square Kilometre Array (SKA) project. The results of our project GaAs and InP based High Electron Mobility Transistors for microwave and millimetrewave optoelectronic and microwave applications are substantial to tackle this problem. The results are also of interest for precision navigation systems, satellite receivers and especially for mobile communication and wireless multimedia applications as 60 GHz Local Area Networks (LANs). Beside NFRA, TNO-FEL will be the project partner. 4 EEA InP based Trans-Impedance Amplifiers (TIAs) will be applied in an Integrated Multiwavelength Terabit/s Optical Receiver to be developed in collaboration with the TU Delft Group Photonic Integrated Circuits (Dr. M.K. Smit et ai., COBRAJDIMES). The goal of the project is Terabit/s transmission speeds. The maximum transmission speed today equals about 10 Gbit/s whereas this project claims the development of Tbit/s communication systems. A joint STW proposal "A Terabit OTDM-WDM transceiver" is under preparation. In the framework ofour developments on GaN based process technology we will contribute to a number of STW projects on blue Light Emitting Diodes (LEDs) and lasers at TU Eindhoven (Semiconductor Physics), Catholic University of Nijmegen (KUN-RIM), RWTH Aachen and RU Ghent (INTEC). First blue emitting LEDs have already been processed in our laboratories (January 1999). Both prof. dr. G.A. Acket (part-time, 0.2 fte) as well as dr. T.G. van de Roer (senior lecturer, part-time, 0.6 fte) will retire in the year 2000. We are very glad the Board of the Eindhoven University of Technology and Faculty of Electrical Engineering will fund a successor of the senior lecturers position with a oneyear overlap. 11.

Signals are acquired, modified, processed, stored and reproduced, preferably performed in the digital domain, making the analogue and mixed signal processing the front-end and back-end of a system on a chip. Due to the ever-increasing improvement in accuracy, speed and dynamic range, very high performance analogue circuits and analogue-to-digita] (AID) and digital-to-analogue (D/A) conversion systems are needed. Because the digital system part is dominating in a system on a chip, a submicron CMOS technology is used for the system implementation. The mission statement of the group is to combine architectural and system knowledge with signal processing methodology and device physics to devise testable systems with optimal properties in a specific sense. This research has fundamental and application aspects, yielding new circuits and system concepts, improved algorithms, prototype systems in IC form and software packages. Our activities on modular IC-design are focusing on the design and implementation of mixed signal circuits and systems with applications in the field of information and communication technology. Aim is to realise high-speed and/or highly accurate building blocks, like e.g. AID and DIA converters, modulators, PLLs, in sub micron CMOS technology and to cope with low power dissipation and small lone joint dissertation with programme 13.

director Electronic Circuit Design Prof.drjr. W.M.G. van Bokhoven EEB die area. Currently (bandpass) sigma-delta modulators have our interest, focusing on these design issues as well as more theoretical aspects, such as stability. Special attention is paid to the application of switched-current (SI) techniques. Mixed signal building blocks can for instance be applied for Neural Networks. Central element is the design of mixed analogue/digital neural networks in CMOS technology with emphasis on onchip training, analogue data storage and influence of imperfections in the electronic realisation. Focus of the research is on implementation of cellular neural networks, error-feedback propagation, weight perturbation and probabilistic training, combining a smaller area and a higher number of updates per second as compared to purely digital implementations. Applications are pursued in recognition of machine printed and hand-written text and print-quality determination. Related to our effort in mixed system design, both CAD design and non-linear circuit theory playa significant role. An important subject in this area is the development of model descriptions and solution algorithms for network analysis tools, e.g. (piecewise linear) simulators. Related to this, research is done on testing of analogue and mixed analogue/digitalcircuits, using new piecewise-linear and interval methods to select optimal test points. A CAD tool is underdevelopment incorporating substrate coupling effects into the placement and routing routines of (semi-)automatic layout tools. 5 EEB Due to a reorganisation of the Faculty, the Materials Group was assimilated in the Electronic Circuit Design Group in 1996. In this subprogramme, special attention is paid to noise. There are four types of inherent noise in materials and devices: thermal, shot, generation recombination, and 1/f noise. Only the physical origin of 1/f noise is unknown. One of our goals is to find the physical origin of 1/f noise in the materials used in microelectronics. Related to the other topics in our group, research is done on the transformation of low frequency conductance fluctuations into phase noise of amplifiers and oscillators, on possibilitiesof 1/f noise reduction in CMOS circuits by switchingtechniques, and on characterisation ofnoise sources in terms ofspice parameters for modern sub micron CMOS transistors (low power, low voltage, high speed) and Si-Ge bipolartransistors. Possibilities are explored to use noise as a diagnostic tool for the quality of devices, for instance to investigate degradation in CMOS. Manmade noise in submicron mixed digital- analogue integrated circuits is under investigation. Due to a reorganisation of the Faculty, the activities on digital signal processing within the Electronic Circuit Design Group were transferred to the Signal Processing Group in 1996. The results of these activities achieved during the first part of the assessment period are not reported here, but are included in the report of the Signal Processing group. 9. Overview ofacademic results Several new circuits in CMOS switched-current (SI) low-voltage low-power design technique were realised, such as a highly linear multiplier and a second order phase-locked loop. Very accurate SI memory cell circuits in 0.5 /tm CMOS technology were realised, that can for instance be used to calibrate current source cells in high speed D/A converters. An 8 bits 100 MHz sample frequency, 10 mw bipolar A/D-converter was realised. Its performance specifications allow for applications in mobile telecommunication. A study was carried out to perform flash AID-conversion based on nonlinear wave propagation. Simulations showed that 8 bit conversion at 300 MHz can be reached, dissipating only a few hundred mw. A Ph.D. project on bandpass Sigma-Delta A/D architectures resulted in a new method to predict the small-signal stability properties ofthis type of circuits. Stability boundaries on design parameters can now be estimated within 5% oftheiractual values for various low-, high- and bandpass architectures. A sixth-order bandpass sigma-delta modulator with a sampling frequency of 40 MHz that can be tuned at 10.7 MHz, consuming 60 mw was realised in documentation 121

director Electronic Circuit Design Prof.drjr. W.M.G. van Bokhoven EEB 5 EEB standard 0.5 micron CMOS technology. Its measured specifications allow for applications in AM and FM signal receivers. As a result of research on neural network design, pulse-stream and switched-current as well as timecontinuous building blocks for application in multi-layered perceptrons (MLPs) were realised in CMOS and tested successfully. Arbitrary network topologies can be realised by combining several of these chips. This flexibility in network topology introduces the need for scaling of parameters, for which an optimal method was derived. The aforementioned circuits were successfully combined to construct MLPs. With a specially developed set-up, the behaviour of several training algorithms in cooperation with our feedforward neural hardware was evaluated. A research project with Philips Research on very dense implementations of circuits for neural networks, based on EEPROM technology resulted in a design of a new analogue multiplier. With this a small, but complete neural network was designed. Besides MLPs, a circuit design was made for a full-range cellular neural network (CNN), to be implemented in MIETEC 0.5 /Lm CMOS process. For its multipliers it was shown, that the application of 2-quadrant types suffices, without loss of generality of the resulting network. The resulting circuitry stands out for its compactness, low power dissipation and good stability. Research on stability of CNNs led to the determination of the basin of attraction in CNNs with symmetric templates. In close collaboration with the University ofturin research was done on the characterisation ofnon-idealities of neural hardware. This resulted in a general method to model non-idealities like offsets and non-linearities in a realistic way. This can for example be used to evaluate designs of ASIC's for neural applications. Activities with Philips Centre for Manufacturing Technology (CFT) and Laboratoires Electronique Philips (LEP) resulted in a digital implementation of a parameterisable neural network on the Philips LNeuro 2.3 processor. With Philips CFT a research project on optical character recognition (OCR) was started. In this project both neural and non-neural approaches are applied to recognise printed text under special conditions. In this project attention is paid to license plate recognition as well as OCR of deteriorated documents and hand-written text. Although the resulting license plate system performs quite well, it is believed that a major improvement of the overall score can still be reached by using a combination of several (character) recognition methods with an optimised voting system. Our effort in general (omnifont) character recognition of low-quality machine printed and hand-written characters resulted in a multistage character recognition scheme, based on a hierarchical shape analysis. This approach is being worked out in more detail and evaluated, based on real-life examples. For ESAIESTEC a module generator was developed and installed running under the Mentor Graphics environment. The module generator allows to design analogue and mixed signal circuits like filters, data converters, amplifiers, etc. The prototype performed well and the circuits that were designed with this tool proved to work successfully. A complete particle detection unit, consisting of four chains together with a flash AID converter and a finite state machine for digital controlling was realised using this tool. Each chain consists of a charge sensitive amplifier followed by a pulse shaping amplifier and a peak-detect-sarnple-hold circuit. The circuit performed successfully. Related to this project, research was done on genetic algorithms applicable to circuit design. Based on generation, mutation and crossover, building blocks are transformed into circuit topologies and dimensioning of transistors takes place. The algorithms were extended to handle design constraints in a convenient manner, resulting in design solutions that do not need to be verified afterwards. Our tool, called DARWIN, proved to be the fastest topology selection/sizing tool at that moment. In another ESAIESTEC project a high-level silicon compiler flow was developed in order to design mixed signal systems composed of modules. For automatic combined topology selection and circuit sizing an approach, based on interval analysis was derived. In this method, the complete design space is taken into account, rather than a local design optimum. The demonstration software was installed at ESTEC and shown to work properly. 122 documentation

director Electronic Circuit Design Prof.ddr. W.M.G. van Bokhoven EEB In the framework of our research on non-linear circuits, attention was paid to chaos. A new technique to use chaos in echo path cancellation was developed, yielding a performance comparable to the so far used adaptive filter approach, but with a much lower hardware complexity. Together with a research scientist from Romania, the use ofchaos in communication systems was further exploited. The properties under which an electronic equivalent of Turing systems produces Turing patterns were obtained. From this study a link was made to nonlinear wave propagation, a phenomenon which occurs for instance in the human nerve system, but also in electronic systems. A strong evidence of wave propagation and its failure in discrete coupled Nagumo equations with piecewise linear behaviour was obtained. With this, new insights in non-linear wave propagation in electronic circuits were gained. Analytic studies were performed on travelling and solitary wave propagation. Propagation failure was studied in simple one-dimensional arrays of identical cells. Proofs of homoclinic and heteroclinic orbits in the associate systems were derived. A basic electronic network was developed producing a triggered traveling wave, where propagation depends on the analogue value put at the boundary. New results were obtained in the extension ofexplicit piecewise linear model descriptions. A new technique to simulate modulated signals in the time- domain for nonlinear systems was developed and shown to have a better performance than existing methods. Also a new method to analyse nonlinear dynamic networks with switching elements in the time-domain was studied and tested. This method can directly be incorporated in standard (PL) simulators and can deal with inconsistent initial conditions. Furthermore. an algorithm was developed to find explicit formulas of the solutions of class-p nonlinear (electrical) networks. 5 EEB A project for STW, dealing with analogue test methods was finished. It makes use of singular value decomposition to automatically select the test signals which predict the circuits behaviour at best. The developed methods were verified on discrete circuits and simulated integrated circuits and performed well. A prototype placement and routing tool was developed to lay-out mixed signal systems. The tool is based on adaptive simulated annealing and takes into account substrate couplings between blocks. Using sensitivity analysis and accurate modelling ofthe substrate coupling, good approximations ofthe influence of a certain placement and routing steps on the performance of the system can be made. Several results were obtained in ourreseach on noise. The 11f noise in magneto resistance layers (NiFe) and in giant magneto resistance layers was investigated. Noise still sets a limit on the applicability of giant magneto resistance materials for low frequency applications. An advanced noise measurement setup for magnetic field sensors was developed. Silicides for low power, low voltage applications were investigated, using noise as a diagnostic tool. The used samples were provided by IMEC (Leuven). A contract on noise characterisation of sub-micron CMOS technology for National Semiconductor was finished. The scaling laws for the noise modelling are still valid down to 0.25 /lm CMOS technology. A Philips fellowship was awarded to work on noise in CMOS transistors. Results on noise as a diagnostic tool for the degradation of light emitting polymers were presented. A Human Capital and Mobility contract on noise, with the participants: GEC-Marconi Caswell, INPG Grenoble, IMEC Leuven. CHS Lille, University Modena, University Patras, Politecnico Torino, CEM Montpellier, and TUE was finished. Hot-carrier degradation in n-type submicron MOSFETs increases the series resistance on the drain side and the relative 11f noise in the drain current. The 11f noise parameter a proved to be a more sensitive diagnostic tool for hot-carrier degradation in submicron MOSFETs than S/(A 2 /Hz). For the relative amplitude of the random telegraph signal noise (RTS) in a MOSFET ~III = lin often holds with N the total number of free carriers. We explained strong deviations from this simple behaviour in terms of strategic (high field regions) or less strategic trap positions (low field region) in a non-uniform channel. The leveling-off in the lin dependence for extremely low N in the subthreshold region was explained via the solution of the Poisson equation showing some charge sharing between inversion and documentation 123

The influence of novel (amorphous gate instead of poly) MOSFET concepts on the noise behaviour was studied. The. noise was simulated in all operating regimes (subthreshold, linear and saturation) and showed very good correspondence with the experimentally observed values. 10. development 5 EEB Since summer 1998, the Electronic Circuit Design group has a new chairman. Related to this, the longterm course was discussed in relation to the chosen research strategies. It was decided, that the group will pay more attention to the design and implementation in sub-micron CMOS technology of mixedsignal circuits and systems with applications in the field ofinformation and Communication Technology (lct). For the realisation ofthese strategies it is important that the vacancy ofpost-doctoral positions on the implementation of analogue and mixed analogue-digital neural networks and on the implementation of low-power digital-to-analogue converters will be filled in. The group is facing a substantial leaving of the staff to industry, combined with an aggravation of the educational tasks. Ongoing and future research activities are carried out mainly in studying and implementing mixed signal circuits and systems. The research activity will mainly be focussed on submicron CMOS technology and partly on GaAs technology using the in-house fabrication facilities. Digital circuitry can be added for signal processing or data processing at low cost. This aspect can be used advantageously to upgrade the performance of analogue circuits. Digital signal processing as part of an AID or DIA conversion system optimises the overall system performance at a lower cost and better reproducible specification. In the field ofneural networks the focus is on analogue circuitry design for the signal path while digital structures are investigated for the training part. Because noise is and will be a key issue in designing high performance mixed signal circuitry, the study and characterisation ofnoise in semiconductordevices will stay a major activity. The project on bandpass sigma-delta converters will be finished. Further studies and possible impementation of an AD converter based on wave propagation are carried out in an other Ph.D. project. DIA conversion architectures are being studied to reach more than 12 bit accuracy for 20-30 MHz bandwidth signals. A possible application can be in the new UMTS standard for telecommunication. Effort will be put in finding a solution for an offset compensation method for the CNN, which can be realised in a dense fashion. Only in this way the compactness of the cell implementation can be fully exploited. The research on general character recognition of low-quality machine printed and handwritten text will be extended. This research should result in a Ph.D. thesis in 1999. Possibilities are being explored to focus more on general vector oriented object recognition in images, using neural networks. The intention is to start a project with the Industrial Vision group of Philips Centre for Manufacturing Technology on this subject. An application in so-called intelligent camera systems seems to be promising. The substrate-aware routing and placement tool will be further developed and tested on several benchmark systems. Eventually better substrate models will be incorporated. Further studies on stability of sigma-delta converters will be done. Finally, research on analysis algorithms will be performed to be used within mixed signal simulators. The use of noise as a diagnostic tool for the quality of materials, devices and circuits will be further developed together with the University of Bordeaux and Bell Labs (Murray Hill, USA). Noise studies will be used as a means to investigate degradation in conductive adhesives. Noise analysis will be performed on low power low voltage CMOS, in cooperation with IMEC. The emphasis will be on phase noise. The low frequency noise and phase noise ofhigh frequency GeSi bipolartransistors will further be 124 documentation

director Electronic Circuit Design Prof.dr.ir. W.M.G. van Bokhoven EEB investigated in cooperation with the University ofuppsala. The so-called substrate cross-talk generation and transmission in CMOS will be investigated in cooperation with Lucent Technology at Murray Hill (USA). In the framework of a STW project on the possible reduction of 1/f noise in MOSFETs by switched bias techniques a cooperation will be started with MESA of the University of Twente. 11. SocietaVtechnological relevance Continuous improvements in integrated circuit process technology and lithography result in a steady decrease in device size, combined with a decrease in supply voltage to 1V. Speeds at the same time will go up and transition frequencies in the order of 100 GHz and above are found in these small size devices. The small supply voltages require advanced circuits and systems in analogue and mixed signal applications to cope with the reduced signal swing. The excellent high- frequency performance of the small size devices requires a better high-frequency signal and noise modelling. Applications in the field of RF signal processing up to 2 to 5 GHz are found feasible. Interesting applications are cellular phone handsets, cordless phones and pagers. More and more functions are realised in the digital domain. In a system with analogue input and output terminals, this will put very stringent requirements of the remaining analogue and mixed signal circuits on linearity, noise level, power consumption, speed (bandwidth), dynamic range, area consumption and supply voltage. Mostly these circuits consist of analogue filtering, controllable gain stages and ND and DIA converters. To minimise the number of external filter elements in a modem (cellular) radio a highly linear AID converter is needed. Such converters need resolutions between 10 and 12 bits with linearity levels at 14 to 16 bits, a power dissipation below 10 mw at sample rates of several tens of MHz. The increased clock speed in the digital system part may result in an increased substrate bounce. This substrate bounce can be reduced using special layout and clock circuit constructions. The large over-sampling ratios used in telecom applications require an extremely high linearity to prevent crossmodulation effects of wide band input signals. There exists a trade-off between the amount of analogue pre-filtering that is used and the resolution and linearity of the AID converter preceding the digital signal processing and filtering operation. Minimising the amount of analogue pre- filtering results in high linearity converters. Identical requirements apply to the multi media and video environment or to optical sensor systems. 5 EEB The group participates in the COBRA research school and is a member of STW/ProRISC.

Special attention is given to the performance under different fault conditions and system transients. 148 documentation

director Electrical Energy Systems Prof.drjr. P.CT. van der Laan EG For an efficient use of the growing number of local and alternative power producers as well as for the redirection of power flow, new diagnostics and information technology will be implemented in power systems. In relation with this development, a target of the group is directed on decision modelling. 8.2. Protection equipment Investigations are directed toward the development and analysis of protection components used in electrical power systems. As a main direction of the group, the so-called hybrid circuit breaker technology has been chosen as a logical continuation of the earlier programme on current limitation. In co-operation with manufacturers, effort is also directed at transient voltages generated by vacuum breaker operation and at maintenance programs for electric fuses. 8.3. Coal and electricity In a further development of research on MHD generators attempts are made to increase the enthalpic efficiency by creating small regions of highly conducting gas. Another goal is to study the fundamental aspects of coal combustion and gasification processes in order to increase efficiency and reduce environmental impact. Also a new method of flue gas cleaning is investigated, using pulsed corona discharges to remove S02 and NO x in a dry process with a valuable by-product. In 1996 the activity of subprogramme 3 was embedded in the Faculty of Physics. As part of a reorganisation of the Faculty, the size of the group was reduced in the reporting period. 6 EG Mission of the Producing a scientific and technical contribution to the improvement of electrical power generation, transport and distribution, emphasising reliability, security, continuity, increase of efficiency and decrease ofenvironmental impact. 9. Overview of academic results 9.1. Analysis ofelectricity networks The research was concentrated on network transients, protection systems and reliability analysis. A large number of specific short-circuits in the 380 kv-network in the Netherlands and in a typical 110 kv-network were simulated with the computer program EMTP. Relations between amplitude, frequency and attenuation of dominant oscillations in the voltage- and current transients, the characteristics of the network and the fault parameters were investigated. Techniques to reduce the complexity ofthe network have also been studied. A computer-based distance protection system for medium-voltage networks has been developed in cooperation with ABB. The system has been tested extensively by static and dynamic tests with signals obtained by EMTP simulations of faults. A rule-based method for designing an optimal protection system for a powernetwork has been developed and applied to some networks. Subsequently, a new method to co-ordinate the operation ofthe relays in power grids with many loops has been developed. This method analyses the topology of the network, using a graph-theoretical approach. A method to localise single-phase earth faults in medium-voltage networks with isolated neutral, based on fault generated transients has been investigated. By measuring the frequency of the associated documentation 149

director Electrical Energy Systems Prof.drjr. P.c.T. van der Laan EG transients and with knowledge of the capacitance of the network, the distance to the fault can be estimated. Further research is needed to improve the accuracy. In co-operation with the SOBU/KUB a stochastic model description for the evaluation of the reliability performance of protection systems as a function of the quality, frequency, etc. to manage preventive maintenance has been developed. Also a model has been developed to analyse the reliability behaviour of protection systems with self-checking facilities. A general method of applying these decision models for maintenance planning of complex networks has been chosen. 9.2. Protection equipment Ageing of fuses, which is responsible for premature fuse operation, has been modelled on the basis of repetitive mechanical stress conditions. Expectations were confirmed by experiments with a range of commercially available fuses, from ultrafast semiconductor protection types and high voltage types to miniature applications. The model was incorporated into an instrument enabling maintenance strategies for protection systems and delivered to one contract partner. 6 EG For vacuum interrupters the origin ofswitching overvoltage generation was analysed, based on inductive and capacitive coupling of phase conductors and three phase virtual current chopping. The hybrid current limiter concept was studied experimentally using a double rectifier bridge and two 10 kv distribution transformers to realise 10 ka at 750 V dc. An electrodynamically driven vacuum interrupter in the main branch was operated in the correct time sequence with a power electronic branch. Theoretically the origin of a number of sources for overvoltages could be determined, enabling the effective choice of counter measures. 9.3. Coal and electricity Concerning the MHD set-up, in a combustion gas high temperature current carrying gaseous conductors were injected. A higher enthalpic and isentropic efficiency has been reached by inhomogeneities. Experiments on the combustion of powder coal, using a shock tube facility, showed the realisation of temperatures between 600 K and 2500 K in an extremely short time (0.01 ms). In the project on exhaust gas cleaning, pulsed corona has been realised with voltage rise times of 10 200 ns and amplitudes of 20-100 kyo Experiments are performed to obtain knowledge of fundamental aspects ofthe discharge. Inception voltage and delay and the velocity ofthe discharge development have been determined. With a CCD camera the diameter of the streamer discharge channel is determined. By emission spectroscopy the temperature of the gas during the discharge phase was obtained and the presence of OH radicals was observed. Gas cleaning is demonstrated in mixtures of air with NO and in exhaust gas. 10. development After the activity of subprogramme 3 has moved to the Faculty of Physics and after the more recent merging of the programmes Electrical Energy Systems and High-Voltage Engineering and Electromagnetic Compatibility, new possibilities are being studied. In the combined group we will study problems in the public power system, especially in view of all organisational changes, within the utility companies. Also the integration ofmany small producers, wind, solar and combined cycle sources, into 150 documentation

director Eindhoven University oftechnology (TUE) Electrical Energy Systems Prof.ddr. P.C.T. van der Laan EG the existing grid is important. Together with KEMA a new project on this integration into the mediumvoltage grid is being started. This project will be embedded in a wider multidisciplinary project, also on economical and legal aspects, which TDO will submit to NOVEM. The development of a new method to design an optimised protection system will be completed; the results will be presented in a Ph.D. thesis. The investigations of the hybrid circuit breaker concept for current limitation will be limited to DC applications; a comparison of the hybrid concept with completely mechanical or completely electronic breakers will be made. The experimental part will be completed in 1999. The planned investigations for those AC applications where no conventional breakers are yet available, will be continued if strong financial support can be found. 11. SocietaVtechnological relevance The relevance of"analysis ofelectricity networks" is demonstrated by the fact that studies are performed under contract with utilities and users ofpower systems. The results add to the improvement ofa safe and continuous power supply. Reliability analysis is and will be introduced in the planning and expansion of power systems. The recently proposed project on the incorporation of many small power generators into the mediumvoltage grid is intended to make a more optimal use of renewable energy sources. 6 EG The relevance of "Protection equipment" is expressed by the fact that our development of automated methods of design and application of switching devices and systems has been in close co-operation with both manufacturers and users. For society the proper application ofthe above mentioned guidelines reduces the hazard of injury, property damage and power failure. The group organises many post academic courses which attract many participants. 12. Other indicators ofquality and reputation Prof.ir. G.c.

As tools we use measuring techniques (sensors and measuring systems) and modem electronics (digital measuring equipment and computer modeling). The studies on avoiding interference have led to the development ofspecial methods, which have become essential tools for our high-voltage research, where intense interference occurs. These EMC-methods can be adapted to situations with less extreme interference, in all sorts ofelectronic equipment. Our research subjects attract many requests for consultation and applied research. 166 documentation

High-Voltage Engineering and Electromagnetic Compatibility I EHC director Prof.dr.ir. P.c.T. van der Laan II ~------- Subprogramme I belongs to the Research School "Center for Plasma Physics andl Radiation Technology." A part ofthis subprogramme (lb) "Applicationsofgas discharges" is in additioll associated with TDO, "Technology for Sustainable Development." Subprogramme 2 is part ofthe Rese<trch School COBRA. Subprogramme la: Pre-breakdown phenomena in gases are the early stages of breakdown in gases at atmospheric pressures. The electron processes are extremely fast, especially in discharges over short lengths. Computer simulation is complex since in the streamer stage space charge modifies the electric field considerably; the aim is to measure and simulate almost to the moment of breakdown. Subprogramme Ib: Applications ofgas discharges use the very intense discharges produced by pulsed corona to inject energy into an atmospheric gas in a short pulse, but fairly homogeneously in space. This injected energy can initiate a variety ofchemical reactions, useful for environmental purposes. Similarly, pulsed coronadischarges in liquids may be useful. Many experiments along these lines have been carried out, in cooperation with industrial partners. Dedicated pulsed power solutions are being developed to improve efficiency and reliability. Subprogramme Ic: In Vacuum insulation we concentrate on avoiding spurious breakdown in a vacuum region. This study, including a fundamental part, uses much past performance; in the present period our effort on this subject is restricted to contracts with industries. Subprogramme 2: Measuring techniques and Electromagnetic Compatibility are two interrelated subjects. We measure to understand EMC-problems and good EMC permits us to do dependable measurements. As a result we are able to do measurements under difficult circumstances. In power engineering signals can be large (high-voltage) or small in the case of partial discharges, which indicate 7 poor insulation in a component. In cooperation with KEMA we develop systems to measure partial discharges in cables and in turbo generators, during actual operation. In EMC we study the differences between circuit theory (Kirchhoff) and field theory (Maxwell). It turns out that an effective suppression ofinterference can frequently be achieved by appropriate changes in the layout. These methods are used to solve problems for a large variety ofproblems; subjects are protection against intense interference as caused by high-voltage breakdown and also EMC of printed circuit boards and of equipment housing. Mission of the In the context of power engineering we exploit the synergy between high-voltage engineering and ElectromagneticCompatibility (EMC) to do basicandappliedresearch. The adaptationofpulsedpower to sustainable technology projects is ofgrowing interest. EHC 9. Overview ofacademic results 9.1. High-voltage discharges la. Pre-breakdown phenomena in gases In attempts to understand and avoid high-voltage breakdown, the very first stages of the breakdown process are important. These "pre-breakdown" phenomena evolve very rapidly when electron multiplication takes place over short distances. Our research, which includes experimental studies, as well as computer simulation has since 1994 resulted in two Ph.D. degrees: in 1995 and early in 1999. The development of an avalanche into a streamer and then up to almost complete breakdown has been studied in Nz, in dry air and in SF6, gases with respectively no, a moderate and a large number of negative ions. Both originally uniform and non-uniform fields were studied by means of time-resolved optical and current measurements. Two-dimensional computer models in which the documentation 167

director High-Voltage Engineering and Electromagnetic Compatibility Prof.dr.ir. P.c.T. van der Laan EHC space-charge modified E-field is recalculated after every time-step, have been developed. Results were the time-to-breakdown and the electron transit time as a function ofthe applied field, the initial electron number, the pressure and the pressure reduced field E/ p. This streamer model is also applicable to partial discharges in voids in solid dielectrics (a main cause of insulation degradation). This has clarified some of the phenomena occurring in void discharges, such as the interaction between discharge and dielectric. lb. Applications ofgas discharges In pulsed corona very intense discharges can inject a short high-power pulse into an atmospheric gas fairly homogeneously in space. The injected energy can initiate interesting chemical reactions. Examples of possible applications are: NO x removal from flue gases, destruction of volatile chemical compounds, cracking of large molecules for instance in biogas, dispersion of gas bubbles in liquids and cold pasteurization of milk. Key elements ofthis growing activity are sustainable technology and pulsed power engineering. Several projects with various industrial partners, run within the frameworks of CPS, TDO and national and international energy research programs. One patent was granted, a second one was submitted. Two pilot units have been built, which produce 100 kv pulses with 10 ns rise time, 60 ns duration and up to 1 khz repetition frequency. These units which are reliable and have good EMC-properties have been used for several research projects. Recent projects are the EU Joule biogas project, an NWO fundedjoint Russian Dutch cooperation, an EnergieNed sponsored field-testing project and a NOVEM contract on 7 cold pasteurization. ERe Discharges in liquids are being studied together with the Separation Processes and Transport Phenomena group ofthe Faculty ofchemical Engineering. Gas bubbles in a non-conducting liquid are dispersed by an inhomogeneous electric field. In a conducting liquid, such as water the voltage has to be pulsed. The principle has been demonstrated and could be used in the chemical process technology where water is often a main constituent. In cold pasteurization pulsed E-fields puncture cell membranes; in that case no discharges are necessary. Detailed diagnostics for corona discharges are being developed in cooperation with the Elementary Processes in Gasdischarges group ofthe Faculty ofphysics. A start was made to let this effort participate in the OSPT research school. 1c. Vacuum insulation After studies on DC voltages, also insulation in vacuum stressed by 50 Hz voltages was investigated. Field emission can then occur at both electrodes and surface charging of insulators becomes more complicated. Contract research was carried out for Philips Electron Optics on high-voltage design improvements in an electron microscope, and for Philips Analytical X-ray for insulator design in an X-ray tube. We cooperated with the FOM Institute of Plasma physics in Nieuwegein on a number of aspects of their 2 MV Free Electron Maser: vacuum- and SF 6 -insulation, beam position diagnostics, tests of HVcomponents and EMC. We also did design calculations for a future depressed collector assembly. As recognition of our work on electrical insulation in vacuum over the last 15 years, our group was asked to organize the 18th ISDEIV (International Symposium on Discharges and Electrical Insulation in Vacuum) last year at our University. About 200 participants from 20 different countries attended this symposium. 168 documentation

director High-Voltage Engineering and Electromagnetic Compatibility Prof.ddr. PC.T. van der Laan EHC 9.2. Measuring techniques and electromagnetic compatibility Measuring techniques The project "Partial discharges in power generators," in cooperation with KEMA and uti lity companies, has resulted in a system for on-line monitoring of the insulation quality of large generators. Special capacitive or inductive sensors have been installed in many generators. A tunable-narrow bandwidth detector has been developed for continuous recording of the partial discharge levels. This detector is tuned to a frequency, between 10 and 30 MHz, where partial discharges are strong and the interference level is low. The detector has a level output, to continuously record the discharge level and a pulse output for the registration of partial discharge patterns. In addition, a method for the localization of discharge sources has been developed. The localization is based on the waveform of the discharge signals, the cross talk between the stator windings and, if more than one sensor is available in a phase, the transit times between sensors. It turns out that additional sensors, such as pick-up loops, are very useful to localize spurious partial discharges. In cooperation with KEMA a study was made on the localization ofpartial discharges in branched cable grids. Also a sensor system has been developed to obtain in the field the phase angle of cable voltages; this information is necessary for the interpretation ofpartial discharge data. This sensor system has been patented. For EnergieNed two diagnostic techniques for "GPLK" cable have been compared: the 0.1 Hz-generator developed by KEMA and the CDA-system developed by Lemke Diagnostics. A number ofpower cables have been monitored, to check whether both systems find correctly the weak sites in the cables. The reliability of Return-Voltage-Measurements as a diagnostic tool to determine degradation by water treeing in "XLPE" cables is being studied. Cables are stressed with a DC-voltage for some time and are shorted afterwards. Ideally, the amplitude of the return voltage is correlated to the density of the water trees; the mean length of the trees determines the time constant of the returning voltage. 7 EHC An introductory study has been started to develop a measuring system to collect information on mediumvoltage (MV) power grids. Since an increasing number of alternative power producers feed into the MVgrid, current distributions should be monitored. Because there are about 80000 MVfLV substations in the Netherlands where one would like to measure, the cost per measuring unit should be kept low. This also makes it desirable to send the measured data to a limited number of central substations, preferably by communication over the MV-cables. Electromagnetic Compatibility Intense interference caused by switching or flashover is common to high-voltage engineering. Electromagnetic Compatibility (EMC) techniques are then essential; EMC is, however, also of growing importance to all electrical engineering, in view ofthe vulnerability and the wide-spread use of modem microelectronics. Methods to protect electronic equipment, including measuring systems and computers, have turned out to be effective for all interference problems encountered. Our methods concentrate on layout modifications to reduce the transfer impedance (ratio ofinterference voltage to disturbance current). This transfer impedance has been studied for many configurations; among them conduits to protect cabling (Ph.D. thesis 1995) and "EMC-cabinets" to protect electronic devices. Both measurements and computer calculations were used to analyze a number ofconduits; it turns outthat non-magnetic conduits are better than conduits made of steel. Similar methods have been used to improve the EMC-properties of cable documentation 169

director High-Voltage Engineering and Electromagnetic Compatibility Prof.drjr. pc.t. van der Laan EHC connectors, instrument houses and printed circuit boards. A setup to measure the transfer impedance of connectors (cooperation with Berg) has been patented. In the analysis of printed circuit boards (Ph.D. thesis 1998) a transmission line model was used to describe coupling effects. The net, common mode, current on outgoing cables, generated by activity on the printed circuit board has been calculated and measured; this current is often responsible for the emission of disturbances. Calculations of common mode currents could be used in routing and placement software to predict EMC-quality at an early stage. To incorporate this so-called Bersier test in the software is still an interesting challenge. A cooperation with the utility company NUON on an "integrated approach to grounding" was started. Both in substations and in buildings there is a need for a grounding method, which protects people and electronics and safeguards against lightning. In a sandy Veluwe area we measured currents and voltages caused by a deliberate short circuit of a 10 kv single phase to ground. Relevant voltage levels were checked in houses for three different grounding configurations. In a recently started cooperation with Holland Railconsult we measured current and voltage distributions in a 25 kv fed railway track in Luxembourg. The 25 kv 50 Hz feeding system should minimize the current through the soil. We will carry out similar measurements with specially developed current and voltage sensors in a first section of the Betuwe cargo railroad. Successful, larger contracts on EMC-problems were: 7 EHC lightning protection ofa naval radio station, ofa naval air field, and ofsections ofa nuclear power plant, numerous EMC-modifications ofindustrial electronic products, for Philips Medical Systems, for ASM Fico and for a high-efficiency central heating unit, tests and later implementation of EMC modifications in Interliner buses. 10. development The departure of the programme director of Electrical Energy Systems has resulted in a merging of that group and ours. A joint project has been formulated.the subject is the integration of many small producers, wind, solar and combined cycle sources, into the existing medium voltage grid (see Subprogramme 2, Measuring techniques). This project in which we cooperate with KEMA will also be embedded in a wider multidisciplinary TDO-project. Other positive developments in our programme are expected to be: The research on pulsed corona (Subprogramme 2) leads to many interesting cooperations and applications within and outside the University, and is expected to do so in the future. Pulsed power for sustainable technology will receive more emphasis. The synergy between the two subjects, High-Voltage Engineering and Electromagnetic Compatibility remains very fruitful. Linear protection methods are effective against intense disturbances, but work just as well on a small scale. Linear methods can be designed and adapted to the situation. Reliable protection is more and more required in a society dependent on microelectronics. Our Electromagnetic Compatibility effort also brings in considerable external funding. Protection of electronics against nearby lightning will be a growing concern in the Netherlands and even more so in tropical countries. 170 documentation

director High-Voltage Engineering and Electromagnetic Compatibility Prof.dr.ir. P.c.T. van der Laan EHC The changes taking place in the world of the utility companies and the pressure to supply electrical power at lower cost but with even higher reliability will lead to more requests for research. 11. Societal/technological relevance Keywords in power engineering are at present: power quality, cost reduction, control of power flow and communication. It can be expected that EMC will be of growing importance, (a) since more significant tasks will be entrusted to microelectronics, (b) because faster and smaller transistors at reduced supply voltages are more vulnerable. Our research subjects: high-voltage insulation, measuring techniques and EMC and in general ourinterdisciplinary approach, are certainly relevant in that context. This is apparent from the large number of contracts and designs realized. We mention here our work on lightning protection of electronics, on EMC design for electronic equipment, our measurements on the quality ofhigh-voltage insulation ofcables and generators and our insulation studies for ESTEC. Our cooperation with KEMA and the utility companies is growing. With five European universities we contributed, within the LeonardolECCE project, to a CD-ROM with an EMC course. During the three years ofthe project we completed the chapters on grounding, shielding and on EMC aspects of PCB design. We also teach many EMC-courses, locally and internationally. We expect more environmentally favorable applications of pulsed corona. Further development of efficient pulsed power and also more tests for new applications are foreseen. 12.

director Electromagnetics Prof.dr. A.G. Tijhuis EM 8. design in brief In the Electromagnetics chair, the behaviour of electromagnetic fields in a wide range of configurations is investigated. These configurations are becoming increasingly more complicated, so that the fields are usually analysed with the aid of computational techniques. Alternaltively, idealized ("canonical") models are studied, or approximate analytical methods are used. Applications typically originate from electrical engineering: we mention in particular antennas, wave-guiding structures, direct and inverse scattering problems, EMCIEMI and bio-electromagnetics. This gives the group a unique position in the faculty and in the Dutch scientific community. We carry out both curiosity-driven, fundamental research, primarily with university means, and society-driven, applied research with a number ofstrategic partners from TUE, research institutions and industry. There exists a strong cross-pollination between both types of work. In collaborations, we focus on the field analysis, while the system aspects are more the contribution of the partner. For the translation to practice, we also rely on the expertise of the TNO Physics and Electronics Laboratory, with which we have established a close collaboration. A specific long-term goal is the development of procedures to match a parameterized configuration to engineering specifications (the design problem) or field measurements (the detection problem). A special policy of the group is to work in an international context. To this end, we disseminate results in international conferences and journals, and we try to exchange researchers and Ph.D. students with universities across the world. In the past five years, we have hosted colleagues from Granada, Paris, Stockholm, Tel Aviv and Torino, and visited the universities of Delaware, Granada, and Tel Aviv. In the period under review, the research was organised in three subprogrammes. The first two were continued from the previous period, while the third one was set up during the last five years. Subprogrammes 1 and 3 are part of COBRA. 8.1. Microwave antennas The aim of this project is to study the electromagnetic behaviour of antennas and its consequences for the design of antennas and antenna arrays. Two central themes can be identified. First, the design of large arrays of microstrip or tapered-slot antennas, and of multi-beam antennas was investigated. From this experience, we also participate in the development ofa large radio telescope for the next millenium. Second, propagationmodelling was used to evaluate the performance ofthe receiver unit and the attached antenna system in advanced indoor communication systems. This project suffered a major setback when dr. M.EJ. Jeuken passed away in November, 1998. 8 EM 8.2. Microwave techniques and radar Traditionally, the group operates an advanced antenna laboratory, with two measurement sites and modern microwave instrumentation. In period under review, the basic theory and the applications of compact antenna test ranges (CATR's) have been further refined. The most important developments were in the design and implementation ofalgorithms for the calibration and the interpretation ofthe measured data. Due to an accumulation of personal problems, the activities in this project had to be suspended in 1997. 8.3. Computational electromagnetics In this project, existing and new techniques for the solution of Maxwell's equations are applied in practical applications covering a broad area of electrical engineering. In the period under review, four main lines of research can be distinguished. First, direct and inverse scattering problems are being investigated with the purpose of determining properties of unknown objects from scattered-field data. documentation 185

director Electromagnetics Prof.dr. A.G. Tijhuis EM The solution techniques developed in this context are also used to analyse simple antennas, their mutual interaction an their coupling to large structures. Second, the behaviour of electromagnetic fields in living tissue has been analysed as a continuation of the former subprogramme "electromagnetic stimulation." Third, the pulsed excitation of wave-guiding structures is being investigated. Fourth, nonlinear optimisation and special modelling techniques are used to solve electromagnetic inverse problems in detection and design. Spin off from this subprogramme is also encountered in the course material and the computer-aided learning software for our mandatory and elective courses. 9. Overview of academic results 9.1. Microwave antennas In 1994, a theoretical and experimental investigation of isolated microstrip antennas and of finite array antennas was completed with a Ph.D. Thesis. This project was funded by the Technology Foundation (STW), and was carried out in collaboration with Signaal. In the thesis, the theoretical analysis of finite arrays of microstrip antennas was based on a rigorous spectral-domain method-of-moments procedure. Mutual coupling and surface wave effects are automatically included. Small arrays and array elements near the edge ofan array can also be analyzed with this finite-array approach. In addition, a sophisticated model for the feeding coaxial cables was developed. In this way, electrically thick, broadband microstrip configurations could be analyzed. The theoretical model was validated by comparing the calculated results with measured data from several experiments. 8 EM In a continued collaboration, infinite arrays of tapered-slot antennas above a ground plane were investigated. As antenna element, the so-called bunny-ear antenna was considered, which is known for its wide-band behaviour and large scan range. The effects of metallic walls, placed on the four sides of the unit cell, on the E-plane scan behaviour of these arrays was analysed. In addition, arrays were examnined that contain two radiating elements perpendicular to one another inside the unit cell. The results were described in two award-winning M.Sc. Theses that appeared in 1996 and 1997. In 1998, a SAl design project was started, which aims at modelling arrays of printed antennas of arbitrary shape and excitation. In cooperation with Philips Krefeld, a study was carried out to design a dual-beam antenna for communication with satellites in different positions in the geostationary orbit. In the future there will be several European satellites in operation for broadcasting. This generates a need for groundstation antennas with two beams. The resulting design satisfies the European Telecommunication Standard (ETS). In a Ph.D. Thesis that appeared in 1997, the theoretical, computational and experimental aspects ofusing adaptive antenna arrays in an indoorpropagationenvironment are described. This project was carried out in collaboration with Philips Research. Two different techniques were developed to model propagation for indoor radio channels. The first one is based on modal theory, and the second one combines a highorder FDTD algorithm and Berenger's absorbing boundary condition. The computations indicate that a wireless system can benefit significantly from the use of adaptive-antenna technology at the mobile handset. A working prototype of an adaptive diversity receiver was evaluated, and alternatives were proposed with comparable diversity and array gains. The theoretical results were verified experimentally for the case of the instantaneous response of the adaptive receiver. 186 documentation

director Electromagnetics Prof.dr. A.G. Tijhuis EM 9.2. Microwave techniques and radar Compact antenna test ranges (CATR's) create a similar electromagnetic environment as in the far field. Such conditions are required for testing ofmicrowave aperture devices or scatterers in radar applications. Dual-reflector CATR's have been commercially available since the mid 1980's. In the period under review, new calibration and correction techniques were developed for advanced applications of these collimating devices in satellite antenna testing and in accurate radar signature determination. In two SAl design projects, ISAR and HRR techniques have been developed for the identification of so-called non-cooperative targets. In the first project, a preprocessing scheme has been developed for motion compensation of ISAR data. The aperture distribution is extracted from the radar signals by an interferometer-like system. Characteristic fragments of the reflection profiles are combined with spectral-domain data to unravel the correlations between the sensors of the interferometer. Motion compensation and focusing then result in a uniformly sampled, three-dimensional synthetic aperture. In the second SAl project, resolution enhancement techniques have been investigated for applications in HRR and ISAR. It was argued that, in most situations, pre-processing in one dimension is more efficient for real-time applications than two-dimensional ISAR. The recognition scheme is based on the observation from physical-optics modelling that the scattering response ofairplanes can be characterized as originating from 10 to 15 scattering centres. In a third SAl-project, the attention was directed towards the development of accurate boresighting techniques for antenna measurements. A method was described for using a flat-plate reference target. The basic idea is to use test-zone fields determined from radar-cross-section measurements in a numerical correction technique for accurate gain and pattern calibration. The method has been demonstrated sucessfully in our own facility and at ESAIESTEC. 9.3. Computational electromagnetics With students, the transient excitation ofa thin-wire segment in a homogeneous medium was considered. Thin wires are perhaps the most simple objects that are capable of radiating, receiving and scattering electromagnetic waves, and are used in a wide range of applications such as mobile communication, ground-penetrating radar and the design of synthetic media and synthetic radar targets (chaff). Topics considered were the derivation of the integral equation, the assumption of a delta-gap voltage, finite conductivity, dispersive and/or lossy surrounding media, coupling, and the effect ofcurvature. Particular attention was devoted to the development of an approximate description ofthe current and the scattered field in terms of waves travelling along the wire; this description is suitable for analysing multiple scattering effects. 8 EM In collaboration with the University of Granada, the interaction between straight thin-wire antennas and plane-stratified media was investigated. This is one of the most simple configurations that exhibits coupling between antennas that generate and receive pulsed electromagnetic waves and a surrounding medium irradiated by those waves. The analysis also gives insight in practical applications such as ground-penetrating radar. For two properly loaded wires over a stratified half-space, the properties of a layered half-space can be identified directly in the current on the receiving antenna. In 1997, a four-year grant from TNO was obtained to extend this research to the detection of buried objects with actual antennas. Since then, the existing software has been extended to the case of buried wires, and the feasibility of pulse shaping to compensate for ringing effects at the wire antennas has been demonstrated. In a joint M.Sc. project with TNO, the coupling was studied between a wire antenna of finite conductivity and an already available electromagnetic model of a human body. Since 1997, the coupling ofelectromagnetic waves into and out ofa closed wave-guiding structure is being investigated. documentation 187

director Electromagnetics Prof.dr. A.G. Tijhuis EM In particular, we consider the excitation ofa parallel-plate or a coaxial waveguide by the inner conductor of a feed cable. By using iterative techniques based upon a linearization in the integral representation for the scattered field, a two-dimensionalpermittivitydistribution in a homogeneous environment was reconstructedfrom field values on a circular contour around, or a straight line above the object at multiple frequencies. Insight was obtained in the fundamental aspects of the reconstruction technique method (resolution, dynamic range) and an efficient numerical implementation was achieved for the solution of the underlying forward problem. Subsequently, the feasibility of using non-linear optimisation techniques was demonstrated, and an embedding technique was developed that will allow us to analyse objects in a more general environment. In 1997, the research into the distortion ofpulsedelectromagnetic signals in the human body culminated in the successful defence ofa Ph.D. Thesis. In this thesis, the behaviour ofpulsed electromagnetic waves is investigated for two representative problems involving biological media and circular loop antennas. In the first problem, a plane-stratified configuration of air, skip, fat and muscle is excited by a circular current loop. The dispersive behaviour of each type of tissue is described by a Debye model. The coupling between the loop antenna and the dielectric half-space is handled by a generalisation of the approach that was developed for the straight wires. For a circular wire in free space, an independent closed-form solution was derived to verify and understand the computational results. The second problem is a feasibility study into the possibilityofdetecting defects in a particular version ofan artificial heart valve. Since the most significant part ofthe valve consists ofa closed, loaded oropen loop ofhighly conducting metal, concepts from the first problem could be used to devise a detection principle. 8 EM In 1996, a three-year research fellowship was obtained from Royal Netherlands Academy of Arts and Sciences (KNAW). The aim is to develop time-domain-modelling methods to analyse and test waveguiding structures on a wide range oflength scales like microstrip and optical waveguides, high-voltage cables and antenna feed networks. An application to continue the project for two years was granted recently. Part of this research was carried out at Tel-Aviv University. A collaboration with prof.dr. E. Heyman and prof.dr. L.B. Felsen (Boston University) led to a new formalism for describing pulsed fields in waveguides in terms of time-domain modes. In collaboration with Plasma Optical Fibre, a theoretical model was developed to estimate dispersion effects in circularly symmetric multi-mode opticalfibres. Finally, a new spectral formulation was developed for the transient excitation ofcoaxial closed and halfopen high-voltage cables. In parallel, inversion techniques developed at KTH Stockholm for one-dimensional configurations were applied to the characterisation of HEMT devices with financial support from COBRA (75%) and STW (25%). Equivalent transmission-line parameters were determined from measurements carried out in the Electronic Devices group. Simultaneously, an extensive literature study was carried out into the available techniques for describing the propagation properties of coplanar waveguides. 10. development In the coming period, our research will be centered around design-oriented electromagnetics. The ongoing Ph.D. projects are compatible with this choice, which is partially driven by societal demands, and partially by our success in combining the conjugate-gradient method and a special extrapolation procedure to solve electromagnetic-field problems with a varying physical parameter. This idea features in several of the projects mentioned in Section 9, but we only recently became fully aware of its potentialities. In 1997, a separate Ph.D. research project was initiated to investigate the limitations of this idea. Other elements of our strategy are the use of advanced nonlinear optimization techniques 188 documentation

director Electromagnetics Prof.dr. A.G. Tijhuis EM and a parsimonious parameterization of the configuration. The necessary experience is available from our research in inverse profiling and antenna design. The first test problem is the design of patch and array antennas with given radiation properties. Further, we intend to concentrate on transient fields. These fields will be analysed directly in the time domain (Ph.D. research started in April 1998) and by "marching on in frequency." Our design strategy and our time-domain modelling can also be used in the context of our research on wave-guiding structures, which will be extended to optical waveguides. Philips Research is willing to fund a collaboration on the design ofhigh-q integrated circuits. To realize these intentions, two postdoctoral projects were started in the first quarter of 1999 to study the use of optimization techniques in electromagnetic detection and in fault-tolerant design of opticalfibres. Points of concern are the availability of permanent scientific staff and the situation of the antenna laboratory. Because of the circumstances mentioned in Section 8, the permanent senior scientific staff at this time effectively consists of the programme director, who also carries the greater part of the educational activities in Electromagnetics. The current temporary staff has the potential and ambition to fill this gap in the next two years. During that time, a carefully controlled growth of the research activities is required. This will slow down the proposed extension ofour research to areas like EMCIEMI and bio-electromagnetics (radiation hazards, ELF fields). The status and the possibilities ofthe antenna laboratory were assessed in 1998 by two teams ofexternal experts. The laboratory can play an important role in the analysis of the electromagnetic behaviour of complex structures and in the experimental verification ofour design-oriented modelling. Decisions on its future are currently under discussion with university management and strategic partners. 11. SocietaVtechnological relevance An increasing demand is observed for the modelling of electromagnetic waves in areas such as antenna design, radio and optical communications, device manufacturing, EMCIEMI and radiation hazards. The collaboration with TNO provides the essential link between theory and practice. In 1998, this collaboration was formalised by the appointmentof prof.drjr. A.P.M. Zwamborn as part-time professor at TUE; a further extension is envisaged. Also in 1998, an informal survey ofour strategic partners was carried out, to help us choose the direction of our research. TNO, Signaal and ASTRON expressed a strong interest in a national collaboration on antenna research as well as a demand for experimental verification, preferably at TUE. Philips Research and POF offered funding to investigate the design of high-q integrated circuits and fault-tolerant optical fibres. New and promising contacts have been established in 1998 with Philips Medical Systems and the National Aerospace Laboratory (NLR). Finally, the kick-off meeting for an intensive collaboration with the Electromagnetics group at the University of Ghent, Belgium, was held in January, 1999. 8 EM 12.

The emphasis is on automated, computer supported interpretation of medical data and/or physiological signals. The ultimate goal is that computerized support of medical activities leads to a higher quality of patient care. The key research notion of the Medical Electrical Engineering research group is monitoring in health care. A strong emphasis is on the development of mathematical models to simulate (parts of) the human physiology, and on real-time analysis and synthesis of domain-specific data and knowledge. Tools that are used are real-time expert systems, artificial neural networks and other advanced methods for realtime multivariate information analysis. During the last five years, most of the research was grouped into one of the following themes: 9 EME EEG analysis. The goal of this theme is to explore the possibilities of using the EEG in a patient monitoring context, where EEG measurements have only recently become practical. In the operating room (OR), the EEG provides information concerning a patient's degree of consciousness. In the intensive care unit (lcu), the information in the EEG helps to estimate the degree of sedation. In neither case, however, do objective measurement methods exist yet. The aim is to develop signal and information processing strategies to quantify brain function during anesthesia and critical care. In our design of the integrated neurophysiological monitor (lnema), various multivariate processing methods (neural networks, adaptive filters, clustering methods) are used for real-time validation, preprocessing and analysis ofbrain electrical activity. This results in a set of neurophysiological parameters which are stored into a real-time EEG database. This database is linked with information about other physiological signals and clinical data and can be accessed by a real-time decision support system which contains knowledge about the (context-dependent) interpretation of the information contained in the EEG. Multi-biosignal analysis and decision support systems. The goal is to provide real time expert systems based patient monitoring systems for use in operating room and intensive care units. The scientific content ofthe project is both the theory ofreal time expert systems and their application in critical real time tasks. A derived goal is the application of"intelligent monitoring" (computerbased monitoring realizing methods that human experts would/could use) in other areas. The first goal of this theme was to explore the possibilities of "intelligent alarms" in OR and ICU, where currently most signals (in critical care sometimes up to 30!) are analyzed independently and where current alarms only compare signal levels with critical limits. In emergencies, where patients may die if the problem has not been solved within a few minutes, clinicians find it 204 documentation

director Eindhoven University of Technology (TUB) Medical Electrical Engineering Drjr. PJ.M. Cluitmans EME difficult to integrate so much information in so little time, and computer support which can rapidly pinpoint the underlying problem becomes necessary. Integrating the "intelligent alarm system" with patient bedside monitors and intensive care information system data-bases is a necessary first step. Currently the emphasis is on expanding the system into a "reminder system" that supports the medical staff in their adherence to clinical guidelines and standard care plans. Clinical control systems. In cases where problems in OR or ICU patients can be detected with very high reliability and where methods to solve these problems can be designed with equally high reliability, the human operator can be relieved from (often time-consuming and attentiondemanding) tasks by a control system. Our emphasis is on the use of real time expert systems for clinical control systems in operating room and intensive care units. The scientific content of the project is the theory of temporal logics in real time expert systems. A derived goal is the application of "intelligent" control systems in other areas. The practical goal of this theme is to automate some life-critical, labor-intensive OR applications. Currently, the emphasis is on the design of several additional controllers (blood temperature, blood oxygen concentration) for a heart-lung machine. Alarm systems for home and ambulatory care. This theme deals with the development of technological aids in ambulatory health care. The main goal is the design oftechnological support that makes independent living possible for the handicapped and elderly. The work for the elderly has close ties with the gerontechnology program of the TUE and focuses on the development of an intelligent safety alarm system that allows warnings and alarms in (potentially) dangerous situations with or without active intervention of the user. The work for the disabled focuses on the design, implementation and evaluation of small-scale aids for people with different motor and/or sensory impairments. In all cases, the ultimate goal of the design and development work is to transfer the results on short or mid-term to the industry. Analysis of 3D-information. The goal of this theme is to extract clinically useful information from three-dimensional data (medical images) for patient monitoring purposes. Increasingly, clinicians use this type of information in real-time, e.g. to provide feedback concerning the difference between actual and desired trajectories of instruments such as drills during surgery. Our research in these types of decision support systems intends to offer a combination of a general approach and a dedicated user interface that is fine-tuned to the specific application. 9 EME The research has its technological basis in knowledge based technology, signal processing, systems theory and systems modeling. The group maintains extensive collaborations with other academic research groups, health care institutions and medical technology industries at national and international levels. Special and long-lasting collaborations are maintained with the TNO Institute for Biomedical Instrumentation (Prof. Wesseling), the University of Maastricht (Prof. Hasman) and the University of Florida College of Medicine at Gainesville, FL (Prof. Beneken). 9. Overview of academic results EEG analysis A software library for adaptive processing of neurophysiological signals stored in the European Data Format (EDF) has been completed. In conjunction with national and international partners, an extension of this format, allowing synchronized storage of continuous data and non-continuous event data, was defined.

director Medical Electrical Engineering Dr.ir. PJ.M. Cluitmans EME frequency and amplitude parameters proved that it is possible to approach the performance of manual scoring and classification of the data by an expert from the Epilepsy Centre "Kempenhaeghe," Heeze. Our group has been responsible for the data management in the (EU-sponsored) International Study of Postoperative Cognitive Decline (ISPOCD). In 15 hospitals in Europe and the USA, data from 1200 surgical patients have been acquired from 1994-1996. This included oxygen saturation data acquired each 10 seconds during 55 hours for each patient (average). The database is extremely valuable in our research on the development of clinical applications for knowledge based and multivariate techniques. A generic, knowledge based technique to validate this oxygen-saturation data was further evaluated and proved to result in correct classification of the validity of all data in 99% of all values. As a reference, manual classification independently done by two experts was used. The main results ofthis project are that in about 10% ofall patients of60 years and older undergoing major abdominal or orthopedic surgery a significant decrease in cognitive functions was observed three months after operation. The hypothesis that prolonged postoperative nocturnal hypoxemia is a possible cause ofsuch cognitive decline however had to be rejected. Therefore, a proposal for a new follow-up project (ISPOCD-2) to look for alternative causes was defined and accepted by the EC. Our group is responsible for all data management issues. Data management, which includes determination ofthe validity and completeness of the recorded data, is increasingly important for medical research. The ISPOCD-2 project consists of the design of a new model ofthe data to be collected and the design and implementation oftools for data acquisition, on-site checking of data integrity and data transfer from the 15 hospitals that take part in the consortium to us in Eindhoven. The international project IBIS was started in 1997. It focuses on the monitoring ofbrain function during surgery and intensive care and early detection of potental brain damage. This shared cost project is supported by the EU and by industry (Datex-Ohmeda, Finland). Our major task in this projectis to design software for a demonstration system to be used in the ICU. Multi-biosignal analysis and decision support systems 9 EME The design, in cooperation with the Catharina Hospital in Eindhoven and others, of a patient monitoring system for the intensive care unit is being continued. A 'reminder' methodology has successfully been designed. The system is now being introduced into daily clinical practice and is steadily being expanded. A major innovation has been the incorporation of a user interface through which medical experts themselves can add their expertise into the system. A validation method checks the clinical utility ofthe tentative expertise which, if demonstrated to be effective, can then be made available for daily practice. An industrial partner (INAD BV, Eindhoven) will distribute the system to other hospitals. In the same project, real-time patient data have been made available to both the medical staff and the critiquing system. Of particular importance in his project is the question how these 'raw' data are best transformed into clinically useful information. Due to a lack of standardization, however, generic interfaces between patient monitors and intensive care information system are still too expensive to be used in non-research hospitals. The research project 'combining expert systems and mathematical models' has been expanded in an attempt to make the model of artificial respiration more accurate, in the hope that diagnostics would become more accurate as well. This hope has not been fulfilled: it appears to be very difficult to obtain accurate, realistic models that allow detection ofsmall deviations from normal operating conditions. The main reason appears to be a world-wide lack of understanding of the precise details of air flows in the lungs. Despite this, the discriminating power that is currently achievable is thought to be sufficient for standard ICU monitoring; this remains to be tested on a large group of patients. In many ofthese research themes, the real time expert systems toolbox SIMPLEXYS, designed in-house and used since around 1988, is of central importance. Recently, this toolbox has been expanded with a 206 documentation

director Eindhoven University of Technology (TUB) Medical Electrical Engineering Dr.ir. PJ.M. Cluitmans EME knowledge acquisition tool which allows computer-naive users to enter and test "knowledge chunks." An easy-to-use user interface allows entry of additional rules into the knowledge base. These entries are subsequently checked for their syntactic and logical correctness. Testing new rules on a sufficiently large database of stored patient data determines their practical value; users are presented with easy to understand bar graphs that indicate how often a rule fired and how often its conclusion was correct or a false alarm. If the conclusions are deemed sufficiently helpful and if the false alarm rate is sufficiently low, the new rules can be added to the definitive rule base that is in daily use. The advantage of this approach is that in many "simple" cases no knowledge engineer is required in the process ofknowledge acquisition. Clinical control systems The expert system based perfusion monitoring system at the department of Cardiosurgery of the Maastricht Academic Hospital has been expanded with two prototype control systems. One stabilizes the oxygen pressure in the blood delivered by the artificial lung. The other controlsthe blood temperature dependent on the phase ofthe operation. Both controllers have demonstrated good performance and high reliability. Currently, these prototypes are being introduced into daily clinical practice. In cooperation with the department of Anesthesiology of Maastricht University, the design of a multiinput multi-output blood pressure controller has been successfully completed. Both systemic and pulmonary arterial pressures are reliably stabilized by having the computer set the rates of three computer-controlled infusion pumps. A similar blood pressure controller has been adopted by the department of Anesthesiology of the Universite Libre in Brussels. Alarm systems for home and ambulatory care In co-operation with the Institute for Gerontechnology (TUE) and Estafette B.Y. (Susteren), an implementation ofa computer demonstration model of a safety alarm system for elderly who need some assisted care in living independently and more safety on their own was completed. Currently, a prototype of such a system is being designed. Analysis of 3D-information Frequently, kidney function in kidney transplant patients deteriorates after the transplant operation. Methods to reliably establish kidney function from dynamic MRI scans (sequences ofkidney images that show the uptake and distribution of a contrast agent) are being investigated. Preliminary results indicate that we have found a method to reliably discriminate between functional cortical and medullary regions. A computer supported surgery system through which orthopedic surgeons can more reproducibly perform knee reconstruction operations by visually presenting the optimal trajectory ofthe drill overlaid on an X-ray image has successfully been completed and delivered for daily use in the OR. The scientific aspect of this research is how to combine model-based information with real-time measurements into more accurate diagnosis and therapy. Currently this system is being expanded, so that it can be the basis for similar systems in other tyupes of orthopedic surgery. 9 EME Throughout all themes, signal validation is important in order to prevent the "garbage in, garbage out" syndrome. In several cases, signal validation itself has been the focus of the research. A "fast flush" technique, for instance, has resulted in a useful method to continuously monitor and improve the quality of invasive arterial blood pressure measurements. A successful investigation of the quality, in particular the degree of damping, of arterial pressure measurements used neural networks. Signal validation also plays an important role in the research concerning reliable measurements ofthe degree of documentation 207

Preliminary results indicate that high quality validation will be possible. 10. development Very recently, the Medical Electrical Engineering research group has been merged with the Signal Processing research group. Some common research themes have already been discovered, especially our common interest in the separation of"signal" (the desired information, often highly context-dependent) and "noise" (the unimportant or undesirable information, which is to be eliminated). Increasingly, our group's effort will be directed towards the new Faculty of Biomedical Technology. For the period 1999-2004, we intend our research to be focused on the development of knowledge based technologies for dedicated, expert systems based monitoring systems. Possibilities to extend the available expertise to other areas than health care will be investigated. The emphasis, however, will be on multivariate and real-time synthesis of medical data and knowledge. The participation in multidisciplinary European research consortia will be continued. 11. Societal/technological relevance Biomedical technology increases in importance in society at this moment. This can be seen both in the increase in education in this area (e.g. the new BMT curriculum at TUE) and in the increase in sophistication in medical support systems that allow ever more complex diagnosis and therapy in medicine, and in the increasing importance of patient record data bases for medical research. Our contribution is mostly in research that can be called basic in the sense that it expands the state of the art, and that can be called applied in the sense that it directly leads to new applications. Major impact is expected to occur in the following areas: 9 EME increase of the clinically useful information that can be derived from (large, preferably multiinstitution collections of) patient data and real-time signals (more informative signal/data processing, "data mining"); increase of the diagnostic power inherent in combinations of many, diverse information sources ("data fusion"); increase of the sophistication of monitoring systems (intelligent alarm systems, critiquing systems, computerized surgery support systems, clinical control systems). Existing national and international co-operations indicate the relevance of our work, especially on EEG signal interpretation (3 large EEC-sponsored projects; an article in The Lancet), multi-biosignal interpretation (our critiquing system will be used to check the integrity of the Dutch national ICU data base), and clinical control systems (world-wide the first multi-input multi-output blood pressure controller actually used in the clinic).

Driving forces behind this development are of societal and technological nature. The reduction of losses, noise and vibration levels in components and systems and of other negative environmental influences, are a centre ofpublic interest. Advances in the fields of materials engineering, ofinformation and communication technology and of computer hardware and software, create new possibilities in calculation, simulation, design, control and monitoring of future (and in some respects of existing) energy conversion systems. 10 Our chair contributes to this expansive field of energy conversion technology with research in its basic electrotechnical disciplines electromechanics and power electronics and the application ofboth in the multidisciplinary (electrotechnical and mechanical) field of conversion systems. For the selection of research subjects we have taken into consideration primarily our own competences and interests; in addition, we have attached much importance to the research profiles ofour colleagues outside TUE and to the needs of industry. EMV For electromechanics we decided to focus on electric machines and actuators, both rotating and linear, in the low and high power range, with permanent-magnet excitation. In our research we aim at maximising power density and efficiency of such machines and actuators, taking into account electric, magnetic, thermal and mechanic constraints. 1Two joint proceedings contributions with programme II.

director Electromechanics and Power Electronics Prof.drjr. A.J.A. Vandenput EMV For power electronics we aim at the conversion of AC and DC electric power, with high flexibility, efficiency and especially high power quality. Therefore, we apply state-of~the-art semiconductordevices in original circuit topologies (mainly voltage source inverters) with optimised components and novel hybrid control. Since energy conversion systems have to be energy-efficient, dynamic, accurate, stable, compact, reliable and sustainable, a concurrent design process is required to combine electromechanics, power electronics and control. In electric drives, which form a primary class ofenergy conversion systems, the characteristics of the mechanical load are essential and indispensable constraints in the design process. Analysis, synthesis, design and optimisation facilities via numerical calculation programmes and stateof-the-art signal processing apparatus are extensively used. The laboratory of the chair is the "conditio sine qua non" for prototype building, testing and developing methods and apparatus to measure functional system parameters, as essential and integral parts of the research programme. The research programme can be considered as equally divided between fundamental, application-oriented and designoriented research. In the (inter)national context the chair is regarded as a respected partner in the design of low-power actuators and high-power machines with permanent-magnet excitation, miniaturised power electronic converters, high-power multilevel converters and field-oriented control of AC machines. Examples are: actuator for electronic throttle control, high-speed permanent-magnet generator, miniaturised battery charger, three-level converter for MRI-applications and sensorless direct field orientation. The collaboration with other chairs ofthe Electrical Engineering Faculty and within the Stan Ackermans Institute (SAI)-postgraduate programme "Mechatronic Designer" will be continued and extended. The long-term co-operation with Philips Lighting and Philips CFT has brought the chair in a unique position. The chair will continue to be actively involved in national and international networks. With respect to publications, much value is attached to SAI-, project- and consultancy reports. In addition, it is our intention to publish regularly in international refereed journals (IEE-Proc., IEEE Trans., Int. 1. Electron.) and to present papers at international refereed conferences (IEEE-PESC, IEEElAS, EPE, ICEM), specialised symposia and seminars. 10 EMV 9. Overview ofacademic results Although magnetic machines of very small size are said to be inferior to equally-sized electrostatic machines, it has been proven that the performance ofmillimeter-sized magnetic machines with respect to torque and speed is incomparably better. The design of a 2-pole 2-phase permanent-magnet micromotor (0.7 mm dia, 1.4 mm length) has been optimised with 2D and 3D finite-element (FE) analysis. Successfully working prototypes have been manufactured and tested. In May 1997 a Ph.D.-research started on the design of a 20 kw, 18 000 rpm converter fed axialflux permanent-magnet machine integrated in a flywheel. It is intended to be used as driving and storage component in hybrid electric vehicles. The performance ofvarious designs at different operating conditions was calculated and checked by FE analysis. The effect of sinusoidal and trapezoidal current waveforms on the efficiency, torque density and drive requirements was investigated. A computer programme to obtain torque, emf wave-forms and their harmonic contents for a given number of slots, number of poles, winding scheme and magnet span was developed. A Ph.D.-project concerning the identification of a synchronous machine by means of a modified stepresponse (MSR) test was defended in June 1998. This "simple" technique has been successfully applied 224 documentation

director Electromechanics and Power Electronics Prof.dr.ir. A.J.A. Vandenput EMV to identify machines in the order of 30 kw. The performance of the test has been closely evaluated by comparing the MSR-test identification results to those of two other standard tests (DC-decay test and Steady-State Frequency Response test). In co-operation with Centre for Construction and Mechatronics (CCM) and Elektromotorenfabriek Nijmegen (EN) our chair has been intensively involved in a project, subsidised by Nederlandse Organisatie voor Energie en Milieu (NOVEM) and Royal Netherlands Navy, to design a 1500kW, 18000 rpm synchronous generator. The rotor, directly coupled to a gas turbine, is provided with permanent magnets, a copper shield damper and a carbon fibre bandage. Special attention had to be paid to the rotor losses, caused by high-frequency magnetic-field distortion, and the cooling of the generator. Measurements on a 80 kw, 9000 rpm scale model were used to verify the design method. The rotor of this generator was also tested at 32000 rpm. Based on these measurements the design of the 1500 kw, 18000rpm generator has been finalised: the rotor size is 250 mm diameter and 650 mm active length; oil cooling is used in stator and rotor. Meanwhile, a joint venture (TUE-Holding, CCM and EN) has been set up for future production and exploitation of the generator and converter. For the connection of the high-speed generator with the utility grid various types of power-electronic converters and current control systems have been analysed; the main objectives were low current distortion, high power factor and compact design. Based on this study it was decided to use 18-pulse parallel-connected rectifiers and parallel-connected inverters between the 600 Hz, 750 Vrms generator voltage and the 50 Hz, 400 Vrms or 60 Hz, 440 Vrms grid voltage with a 1000 V DC-link voltage. A prototype 250 kw Insulated Gate Bipolar Transistor (IGBT)-inverter with 880 Vde input and 60 Hz/440 Vrms output has been tested successfully. Based on a hybrid system (DSP and analog computation), real-time simulations have been performed to analyse some control aspects related to the parallel operation of two 250 kw IGBT-converters. Within an extra one-year project, financed by NOVEM and in collaboration with KoninklijkInstituutvan de Marine (KIM), the system, consisting ofthe gas turbine, the generator and the converter, was simulated and analysed in real time on a multi-dsp system. Six 30 kva IGBT-converters have been manufactured after designing and testing the prototype in cooperation with Energie Centrum Nederland (ECN) and Prodrive B.Y.. Special features are: compact design, multi-purpose (1 to 4 phases) set-up, short-circuit protection for each IGBT and DSP-control via optical fiber. Such a converter has been used to analyse and test fundamental issues related to power quality and decoupled control of active and reactive power in Unified Power Flow Controllers. Based on these results, an industrial prototype has been implemented by Prodrive B.Y.. In a contract-research programme with Philips Medical Systems (PMS), a three-level high-switchingfrequency inverter for Magnetic Resonance Imaging (MRI) applications has been analysed with respect to stability and control. A low-power prototype has been built and successfully tested. Consequently, in September 1997 a Ph.D.-research started within the frame of a Stichting Technische Wetenschappen (STW)-project, co-financed by PMS. The aim is to increase the power level of gradient amplifiers used for MRI-applications, taking into account system stability, efficiency and downsizing. Therefore, the output voltage and the switching frequency have to be increased. The nested-cells inverter, provided with soft-switching, seemed to be well suited. A first prototype has been built and tested successfully at 1]00 Vde input voltage, ]00 A load current and] 7 khz switching frequency. Some novel control issues have been published in refereed conference papers. 10 EMV The chair has developed a new systematic approach for discrete-time small-signal modelling of cyclically switched converters. Effort has been made to describe in detail the theoretical background in a journal paper. This methodology is also the basis for analysis, simulation and design ofa high-quality multi-level current converter (l0 kw) for electric welding, to be developed in the frame ofco-operation with the University of Varna (Bulgaria) through a visiting Ph.D.-student. documentation 225

director Electromechanics and Power Electronics Prof.dr.ir. AJ.A Vandenput EMV The research in the field of low-power electronics, sponsored by Philips Lighting B.Y. (PLBV), was directed towards the application of piezo-transformers in gas discharge lamps, level-shifters, galvanic insulation and small power supplies. A lot of circuits have been investigated and some prototypes have been successfully implemented. Theoretic insight and practical know-how have been transfered to PLBY. Since 1998 research effort has been directed towards the optimization of component values in different circuit topologies, by using Matlab-toolboxes. As far as control ofelectric drives is concerned two Ph.D.-projects have been finished. The first one dealt with stabilising and correcting the voltage/current model, used in direct-field-oriented induction motor drives, at low stator frequencies. This was done by adding two feedback loops in the model and finding optimal gains as a function of the stator frequency and the load of the machine. The control circuit was implemented in a TMS320C40 multi-dsp system. This system was also used for real-time simulations and experimental verification in the second Ph.D.-project dealing with remedial operating strategies in case of various converter faults (asymmetric supply) in direct-field-oriented induction motor drives. It was successfully proved that, using dedicated control techniques, normal operation of the drive is still possible. An ongoing Ph.D.-project, financed by Siemens AG., Erlangen-Germany, deals with sensorless directfield-oriented control of a current-regulated VSI-fed induction machine at zero stator frequency. A magnetising-current injection method, taking advantage of the saturation of the machine, has been developed. Two test set-ups (slip-ring and squirrel-cage machine), provided with dedicated dataacquisition and data-processing electronic equipment, have been built and put into operation. So far, the method has been successfully verified for slip-ring induction machines. In the frame of a three-year KNAW postdoctoral fellowship research has been done (partly in our chair, partly at the University of Wisconsin, Madison, WI, USA) on flux-based control of inverters for drives, PWM rectifiers and active filters. The chair has also been actively involved in the European Union DGXII-Project "Train" at CRIS Ansaldo, Naples, dealing with the design and implementation of an optimised direct-torque control (DTC) of induction machines. Finally, in October 1998 a post-doc started the final stage of a research programme, partly subsidised by the "TUE-Stimuleringsfonds," dealing with the analysis, design and manufacturing of a computercontrolled high-dynamic test bench for electric drives. 10 EMV As it ultimately proves the confidence put by industrial companies in our work, the chair attaches much value to research projects performed in the frame of the SAl-postgraduate programme "Mechatronic Designer," the University Technologic Institute (UTI)-IPPVlMechatronics and consultancy work. In the evaluation period 16 SAl-reports have been written by AIO-2s, supervised by staff members of our chair. Most of these one-year projects, performed in various companies, resulted in well-functioning prototypes; one of them has been awarded the Universiteits Fonds Eindhoven (UFE)-Designer Prize in 1998. In addition, 4 UTI-reports, 6 consultancy reports and 43 master theses have been written. The chair transfers its knowledge and experience to the curricula by means of 5 compulsory courses and 6 elective courses. 10. development Since many Original Equipment Manufacturers (OEMs) are located in our region, manufacturing servomotors for production-machines, in which volume, speed and control are essential criteria, the chair will continue the research in small rotating as well as linear machines and actuators with permanent-magnet excitation. Great challenges still exist in the area of multi-dimensional and opto-electromechanical 226 documentation

director Electromechanics and Power Electronics Prof.drjr. AJ.A. Vandenput EMV actuators. Various disciplines (electro-mechanics, tribology, optics, dynamics, power electronics and control) have to be combined in a concurrent design process in order to achieve an optimal integration of motor, amplifier and controller. The chair will continue to contribute to the sustainable technologyofenergy conversion systems, as far as electromechanical storage systems and decentralisedenergy production units are concerned. A prototype ofan axial-flux permanent-magnet machine, integrated in a fly-wheel and suppliedby a powerelectronic converter, will be manufactured, and tested by means of a computer-controlled test bench. In addition, the constructionofthe prototype ofthe 1500kW/18000 rpm generator will be finished and the generator will be tested at no-load in our laboratory. Depending upon these test results the design ofthe generator could be optimised in several aspects. Power electronics, providing flexibility, energy savings and power quality in conversion systems, will continue to be emphasised. A 500 kw/1200 Vdc power-electronic converter prototype for grid connection of the high-speed generator will be built and tested. Fluid cooling of the semiconductors and an optimal design of the mechanical construction will be pursued to achieve a compact design. In the project about gradient amplifiers used for MRI-applications, soft-switching techniques will be further analysed and tested in order to reduce the losses in the nested-cells converter, aiming at achieving a higher power per volume ratio. Meanwhile, it became clear that the outcomes of this research are also applicable to converters for electric machines or transmission and distribution systems. In what concerns converter modelling, the primary agenda will remain the development of discretetime modelling techniques for fast circuit simulation and optimisation, based on Matlab-toolboxes. The long-term goal is the development of design-oriented methodologies aiming at optimisation of arbitrary penalty-functions, robust design, design centering, and (statistical) characterisation of failure mechanisms. With respect to electric drives, the research on sensorless direct-field-oriented control of induction machines with a squirrel-cage rotor will be finalised. Currently, research efforts are being directed towards the dynamic testing of drive systems including machines and inverters. The test bench, using modem control techniques implemented in multiple DSPs, will run fully automatically, by putting the drive system through predetermined drive cycles and taking numerous measurements. Post-processing will be performed on the obtained data to enable such measurements as power and energy efficiency. The scope ofthe research will be expanded to include other topics, such as energy-efficient control strategies and on-line identification techniques for machine parameters. Collaborations with other research groups, at TUE, in the Netherlands and abroad, will be continued and extended. As in the past, staff members will also devote themselves to the SAl-postgraduate programme "Mechatronic Designer" and consultancy work for industry. 10 EMV Finally, we hope that the vacancy of the associate-professor position will be filled up soon. 11. Societal/technological relevance The chair Electromechanics and Power Electronics is dealing with a sustainable technology for energy conversion systems, aimed at flexibility, high performance, energy and material savings and power quality. To reach this goal we are exploiting the brains (lct, embedded systems) for the muscles (converter-fed actuators). Miniaturised systems, generally produced in large quantities, are characterised by a low consumption of energy and materials. In addition, the application of (new) rare-earth permanent magnets will improve functionality. Rotating, linear and multi-dimensional actuators are used to "drive the ICT- and OEM- documentation 227

---'-_._---------------------------------- University Electromechanics and Power Electronics EMV director Prof.dr.ir. AJ.A. Vandenput world," and are applied in computer- and medical apparatus and in audio-, video- and other consumer products. High-speed electrical machines are appropriate and relatively cheap in decentralised generation, storage and propulsion systems, where small volumes and weights are decisive. Power electronic converters with digitally controlled semiconductor devices assure a highly efficient and very flexible conversion of electrical energy, as well as the dynamic characteristics of the system. In addition, they are able to guarantee power quality in AC transmission systems. Besides the improvement of industrial productivity and product quality another dimension of importance of power electronics is being realised: energy conservation and the corresponding control of environmental pollution. Adjustable-speed electric drives result in substantial energy conservation. AC servo-drives, provided with field-oriented or direct-torque control, are continuously increasing their share of the market compared with hydraulic and pneumatic servo-drives. 12.

To reach this goal the chair is actively co-developing the fundamentals of control engineering, viz. system and control theory. Knowledge and understanding of physical processes is based on models which are derived from prior knowledge (modelling) and/or measurements ofprocesses (identification). The chair focuses on identificationtechniques and controller synthesis methods for uncertain and non-linear models. Fundamental research is carried out with this focus in mind. Applications are aligned with this long-term, scientifically-based research on modelling, identification and control. With respect to applications, research is being carried out on questions related to system integration for component selection, measurement strategies, control topology and a trade-off between conflicting requirements for performance, robustness and cost-effectiveness. Modelling Modelling concerns the deductive process of obtaining a mathematical description of the behaviour of a dynamical, in general, physical system. Both input-output models, such as block schemes, transfer functions and state-space models and interacting models, can be used. Behavioural models consist of sets ofsignals with no distinctionbetween inputs and outputs, which yield additional flexibility. Presentday theory only supports models with a finite dynamic range (ratio between the largest and the smallest relevant time constants). Typically, fast transients cannot be described appropriately and are replaced by algebraic equations (differential algebraic equations) or by mode switches among different dynamic behaviours. A further investigation of the interaction between time-continuous models, logic rules and discrete event dynamic systems has led the chair's research into the area of hybrid systems with a focus on analysis and synthesis. Recently, hybrid systems have received much interest due to their ability to describe complex systems such as embedded controllers. Control and identification 11 ER Robust control methods are based on models with an explicit description of the uncertainty described by hard bounds or by statistical information. As many processes exhibit non-linear behaviour the objective is to formulate and investigate new identification methods to identify systems with some classes ofnon-linearities, such as saturation, rate limits, polynomial or neural net approximations. Model predictive control is the technology that has been broadly adopted by industry to realise multivariable process control underinput/outputconstraints. By merging system identification and control, the section anticipates the strong industrial need for improved process control and higher quality products. In line with this, the fundamental research focuses on the estimation and control of systems with uncertain documentation 239

director Measurement and Control Prof.dr.ir. P.P.J. van den Bosch ER or behavioural models. For the analysis and synthesis of non-linear processes with constraints, model predictive control and II-optimal control techniques are investigated. Research on controllability and directionality analysis of multivariable processes yields guidelines for the selection of appropriate controller structures. Applications The section has carefully selected applications that fit both its long-term research and allow co-operation within the university and/or with industry. In general, the partners provide the application-specific knowledge. Emphasis has been put on electromechanical devices, such as high-performance servo systems and active magnetic bearings, multivariable control in process industry and, recently, embedded controllers and biomedical applications. Examples are automotive control in 2 STW projects, viz. engine control to reduce exhaust gasses and the measurement and control of electronically-guided vehicles. 9. Overview of academic results In the period 1992-1995 the chair participated in an ESPRIT-III, Project 6042 "Hephaestos 2." A camera measurement system provided 3D measurements and position data for very large-scale unique workpieces for automatic arc welding by industrial robots. The research was successfully closed with a demonstration ofthe results at a shipyard in Athens in the presence ofreviewers from the ESPRIT CIME administration in Brussels. In 1994 the Measurement and Control section decided not to continue its research on robotics and process computer systems. The research on system identification for process control has been extended to include identification for robust control and for electromechanical devices. In particular, electrical drives, active magnetic bearings and control systems in the automotive area have been studied with respect to questions related to their physical modelling, identification and control. With the start of the new BMT curriculum in 1997 an attractive application field for the study of complex, non-linear and non-stationary systems and signals has led to new and challenging questions for research in measurement and control. Modelling The achieved scientific results comprise the following aspects: 11 ER The behavioural theory of dynamical systems departs from the common input-output point of view and, instead, considers systems as sets of signals. This idea has led to a substantial theory for modelling, identification and control. Results have been derived and published for the representation of Lz-systems, model approximation, identification and robust control design in an input-output independent setting. This fundamental research is part of a larger investigation of behavioural systems in The Netherlands. Within the class of hybrid systems, systems with complementarity variables are studied. Due to their impulsive and mode-switching behaviour, issues such as the existence and uniqueness of solutions become non-trivial. Conditions guaranteeing well-posedness have been specified, not only for linear but also for rational complementarity systems. Techniques for time simulation and stability analysis of these systems are investigated. For dissipative systems stronger results have been achieved. The mixture of continuous time dynamics, state events and time events makes this research an integral part of hybrid systems. The chair focuses on hybrid models for analysis and synthesis with sufficient expressive power. This research is receiving increasing interest from other researchers and industry. Invited presentations have been made within the university, Philips and at international conferences. In particular, the ability to describe and 240 documentation

director Measurement and Control Prof.drjr. P.P.J. van den Bosch ER analyse embedded controllers within the hybrid systems framework has attracted industrial attention. Co-operation within DISC, EESI and with Philips CFT has stimulated this research topic. Control and identification The following results have been achieved: Robust control, for example Hoo and {l-synthesis methods, is based on nominal models with error bounds or error sets. Several approaches, described in 4 Ph.D. theses and many articles in our top journals (Automatica, IEEE Trans. Autom. Control), have been used for obtaining these error bounds or sets. Models have been derived in the frequency domain with error bounds. Hard bounds on the parametric uncertainty, both in transfer functions and state space models, are derived. These hard bounds yield worst-case controllers that tum out to define conservative controllers. For this reason probability density functions have also been introduced to describe the uncertainty of parameters. Based on statistical information, algorithms for the synthesis of average optimal controllers have been designed using analytical results and randomised algorithms. These controllers exhibit a better performance while maintaining stability, as shown for the active damping of trucks. Non-linear systems become increasingly important when high-performance control is required. The research has been focussed on grey, neural nets for modelling and control of the non-linear dynamic behaviour of a polymerisation reactor. Within 2 STW projects processes with essential non-linearities had to be controlled. One project, carried outjointly with the Faculty ofchemistry, deals with the modelling and control of the non-linear behaviour of catalysts. The goal of the project is to develop novel control systems for ultra low emission vehicles, based on a firstprinciple model of a catalyst. In 1998 a project was started with Multin and Applikon to design a robust, adaptive controller for highly non-linear biochemical reactors. Fundamental properties ofthe Model Predictive Controller have been studied. The stability of a receding horizon optimal controller has now been established under weak conditions. Based on our knowledge ofmpcs and system identification we are participating in a large consortium with universities (RWTH Aachen, TUD, MIT, NU Trondheim), suppliers (MDC, IpCos) and industry (Bayer, Shell, Statoil) from Europe and the USA to design and realise the next generation of MPCs. The main goal is to integrate control and optimisation for process industry, for example for distillation for faster changeovers and tighter product specifications. The behavioural representations of L:2-systems have been used to derive new algorithms for the synthesis of Hoo-optimal controllers. The basic feature of these algorithms is that control variables and measured variables ofthe system do not need to be distinguished priorto the design of the control system. It is believed that this has major implications for control system design. 11 Other optimal control techniques are currently being investigated in this setting. ER Applications Knowledge on modelling, identification and control has been applied to several processes which do not satisfy the linear, time-invariant requirements. Even so, useful results have been obtained. Research has finished on measuring 3D geometrical properties of a fixed object with 2D images of several fixed cameras using scene verification with an imaging model. A Kalman-filter like structure was selected utilising synthetic image modelling for improving the measurement accuracy. This research is continuing in another direction with the retrieval of 3D information documentation 241

director Measurement and Control Prof.dr.ir. P.P.J. van den Bosch ER from 2D-images ofone moving camera (structure from motion). The problem ofcorrespondence between a sequence of images is being investigated and a systematic way of 3D reconstruction of objects is being studied. The research on robot control ended with a Ph.D. thesis on a real-time collision avoidance strategy for autonomous robots equipped with ultra-sonic sensors. Using artificial potential fields stabilising controllers have been derived. Several applications ofelectromechanical systems have been studied and successfully described in Ph.D. theses and articles. One study concerned fast, recursive identification techniques with complex signals applied to induction machines. This approach has led to an attractive method for dealing with the revolving currents and fluxes in induction machines avoiding expensive sensors. Using only measurements ofcurrents and voltages, the velocity of the motor could be estimated. The basic control of CD-ROM designs has been studied for achieving high data throughput, considering aspects of mechanical, electrical and signals and systems. Scanners with air or active magnetic bearings for both accurate and fast 3D-measurements have also been studied. Several prototypes have been designed and some were analysed with FEM techniques. Fixing three degrees of freedom (position) has been achieved. The main remaining problem concerned accurate angle measurements (l: I 0 6 ) for 2 rotations. This research has attracted interest from Kranendonk (Tiel) and TNO-Mechatronics. STW is financing a study on the measurement and control of the lateral behaviour of electrically-guided vehicles for public transport. An accurate and reliable measurement method has been realised using magnetic markers in the road, resulting in a patent and publications. A stabilising controller with feedback linearisation has been designed for all 4 independent controllable axes of a bus. This project will be realised in Eindhoven in co-operation with, amongst others, NedCar, Frog and Simac. The Ph.D. student involved in this research visited Berkeley, USA, for 3 months to participate in research on guided trucks. 10. development 11 ER The chair is aiming to carry out about 8 Ph.D. projects simultaneously, with financing more or less equally shared by industry, STW, faculty, and university priority programs. It is well aware of the necessity and the benefits of co-operation in national and international scientific networks. The chair continues to be actively involved in national and international scientific networks, such as DISC and European networks (ERNSI, SIMONET, and NICONET). The chair intends to contribute to, and to participate in the organisation of international scientific conferences and to participate in the editorial boards of scientific journals. The valuable co-operation with industry will be continued. The chair is becoming more and more involved in the new Biomedical Technology study and research programme. This will influence the research into non-linear and non-stationary systems and signals. The fundamental research of the chair involves controller design that combines high performance specifications in normal usage with robustness to combat incidental process deviations. Further study will be made of the interaction between identification and robust control in the so-called behavioural setting. The ll-optimal control research and the investigation ofdissipative systems will be continued and intensified. Research on hybrid systems, with respect to both modelling and synthesis issues, coincides with the EESI research programs and industrial interests and will be continued. The applications of the research will be oriented towards scanners with active magnetic bearings, electrically guided vehicles, 3D-measurement systems and process control. It is expected that in 1999 the decision will be taken to build electronically-guided buses in Eindhoven for about 160 passengers. The chair is scientific and technical advisor to Frog Navigation Systems who will realise the measurement and control system for the lateral guidance ofthis bus. In co-operation with TNO Industry 242 documentation

director Measurement and Control Prof.ddr. P.PJ. van den Bosch ER (Mechatronics) scanners will be realised. Robust and adaptive controllers for biochemical reactors will be designed for Applikon. 11. Societal/technological relevance In many industrial products and production processes, a trade-off has to be made between performance/quality and price. By using accurate measurements, appropriate controllers and cheap components, attractive cost-effective products or production processes and high performance/quality can be achieved. Hence, measurement and control can contribute a deciding competitive advantage to products and production processes. For example, measurement and control enables the construction of cheap but highly accurate and fast electro-mechanical devices such as CD-players, disc drives for computers and photo cameras. Many production processes are now becoming more economical, safe and reliable due to the use ofmeasurement and control techniques to realise required product specifications. Moreover, a well-controlled process will not unintentionally disturb or pollute the environment and minimises the use of energy and raw materials. Many markets are becoming "demand-driven." Consequently, a fast and accurate response to the needs of the customer is becoming a prerequisite for financial profit. Controlling processes to enable fast changes between guaranteed product quality allows this fast and accurate response. The chair's research programme meets these industrial needs, for instance in process control (bioreactors (Applikon), distillation (Bayer», automotive control (Frog Navigation Systems) and electromechanical systems: waferstepper (ASML) and CD-ROM (Philips-CE). Various Master thesis projects dealing with real industrial problems formulated together with industrial contacts have been carried out. Our research also feeds the educational activities that are focused on the undergraduate curricula of Electrical Engineering (10 lectures) and BioMedical Technology (3 lectures), the graduate curricula of SAl and DISC and on dedicated post-academic courses of PATO for industry. These educational activities attract considerable interest from undergraduate and graduate students and from industry. Over the past 5 years the chair has produced 95 M.Sc. theses, 8 SAl Master in Design theses, 7 Ph.D. theses, 7 DISC graduate and 5 post-academic courses. 12.

Historically the research focused on the design ofintegrated circuits the way those developed over the last twenty-five years. In the beginning the most important items were simulation (circuit-simulation to be precise) and automated layout design. Two trends developing over the years had a significant influence on the evolution of the research program: 12 ES As the complexity and density of integrated circuits rose two orders of magnitude in every decennium (Moore's law) Ie's were offered for use to the industry in a growing variety of forms. Those forms range from the (classical) customized application specific chips over gate arrays, FPGA's, PLD's, processor cores, special purpose processors all the way to supercomputers. As the Design Technology evolved over the last decennia it was forced to embrace more and more application specific aspects ofmicroelectronics design. The design process was formalized up to higher levels ofdocumentation. The documents had to be matched to the traditional models and the expert ways of thinking customary in fields like computer design, telecom-systems, consumer-electronics, process-automation, medical systems, automotive-, airborne- and spaceapplications, just to name some examples. The growth of the complexity of integrated circuits is very likely to continue over the next decade. The targets of the industry have been laid down in the so-called "roadmap" of the US "Semiconductor 264 documentation

director Design Technology for Electronics Systems Prof.Dr.-Ing. J.A.G. Jess ES Industry Association" (SIA). This document commits the industry to a technology integrating 500 million transistors on one die around 2012. It is an essential issue for the industry to face the consequences and design its product line according to the abilities ofthe semiconductor manufacturers. This in tum presents great challenges to the area of Design Technology. It is our mission to contribute to the methods intended to master the complexity ofthe design challenge (according to the target set by the SlAY in a fundamentally innovative way. The core of our research efforts directs itself to the area of (semi-) automatic synthesis and validation in layout, logic and architectural design ofmonolithic integrated circuits. Logic and physical design is our primary contribution to the "COBRA research school."an important challenge is in the degradation of the interconnect quality with shrinking geometric features of the technology. Another is the control of the performance in terms of area, delay and power with the layout structures becoming so small and dense and so deeply structured. A third one is connected to the imperfection offabrication processes and the necessity to control the sensitivity of products with respect to those imperfections. Architectural design is our contribution to the "Eindhoven Embedded Systems Institute" (EESI). On that level tool design can in part be understood as the generalization of compiler construction. However the problem of building compilers in this way unfolds into a two-dimensional manifold along the axes of the various technologies and the various applications. Traditionally the applications we deal with show some affinity with the signal processing area where many contacts with industry are maintained. Those contacts include industries heavily engaged in the development of consumer products aiming at multimedia environments in homes and offices. The scope of this area broadens continuously in the sense that fundamentally new system architectures are conceived deviating quite radically from the classical concepts ofpipelines and caches. In particular new memory architectures replacing caches are of interest. Communication on the chip is going to include a large variety ofconcepts including structures as powerful as a crossbar switch. Also all chapters on operating systems will probably have to be rewritten in the near future. The basic reason is that consumerelectronics and telecommunications develop technical needs quite different from the past. Low power, portability, huge computation loads (in connection with real time video handling and graphics processing), sharp real-time budgets, high volumes and low prices enforce a novel approach to the making of those products. We aim at a gamma of methods and tools that can be structured into design flows by scripts possibly involving tools from other sources solving essential steps in the design and validation flow. 9. Overview of academic results Architectural design Background In view of the evolution of the IC technology the (US-) computer industry basically continues on the foundations of the previous twenty years. The central concept is the general purpose processor shaped to a large variety of applications by software. The performance of the processor is boosted by the IC technology enabling higher degrees of integration (thus reducing cost), faster clock speeds and denser memories. Parallelism enters by the concept of the RISC pipeline and by involved cache strategies enhanced by "Very Long Instruction Word-" (VLIW) or "Superscalar-" architectures. The product lines are planned over a long period of time - the Intel processors of seven years from now are already on the drawing board. 12 ES documentation 265

director Design Technology for Electronics Systems Prof.Dr.-Ing. l.a.g. less ES An alternate mainstream is established by the consumer electronics and telecommunications industry developing a very different approach to architectures. For this industry it is very natural to think in terms of embedded parallel processes interacting in a variety of ways. Therefore the architecture of media chips provided by this industry is traditionally an assembly of processing blocks. Some of those blocks are fairly specialized such as for instance the MPEG en- and decoders (like the I.Mc.IC), radio front ends or format converters (like the MELZONIC). On the other hand more and more functions in consumer products are implemented in software on general-purpose controllers (such as the 8OCSl) or DSP processors (like the TMS-series). The development of the TRIMEDIA processor by Philips Research (intended as a high performance DSP for video and audio processing) enhances this trend. In this concept integration is synonymous with embedding more and more of these functions together into one chip. The chip is therefore a complex composite of a large variety of functions, where some are implemented as specific hardware footprints and others are executed by multifunctional processor blocks. This delivers a number of very interesting new perspectives for fundamental innovations in terms of hard- and software architectures (for instance in terms of low power engineering or high performance parallel operation). It also presents a number of fundamentally new challenges for the Design Technology. In particular the optimization of the economy of the hardware- and softwarearchitecture in terms of throughput, volume (area), packaging and power requires new techniques with much higher performance compared to classical compilers. Our contribution The contributions of the Design Technology chair to the field of architectures have to be placed before this background. We completed the design of the PROPHID processor. The PROPHID processor is essentially an array ofapplication specific units (among them memory units). These units communicate via FIFO-buffers ("first-in-first-out buffers") and a crossbar switch. The essential innovation is the control scheme for the data streams, which is designed to guarantee the throughput of the high performance (video-) streams in the first place. Another is the approach to structure the memory replacing caches by application specific structures. A prototype of this processor has been actually fabricated and tested by Philips Research. While most novel parallel architectures address "Instruction Level Parallelism" (ILP) the PROPHID architecture allows for taking advantage of "Task Level Parallelism" prominently present in media applications. It is now part ofa platform ofmedia processing elements together with the CHEAP-architecture, the COCOON environment (specifically designed for portable (low power) applications), the TRIMEDIA processor and the series of MIPS processors (all more or less originating from Philips Research and Philips Semiconductors). 12 ES Aware of the overwhelming significance of software technology for today's and future media products we directed many ofour efforts to innovations in this area. We contributed new results to code scheduling ("constraint driven scheduling," a fundamentally new approach based on "constraint propagation") and the techniques of "code motion" and "speculative execution" in the presence of conditionals. Our methods deliver a significantly larger scope for optimization than classical compiler techniques (like "trace scheduling") by being able to simultaneously analyze the entire code of a task. Also they help to restrict the threat of a state explosion in the controller of the parallel processing structure. Also we investigated the potential of genetic and neural paradigms for code optimizations. Rather than justa single compiler the media platforms require a framework oftools that can be structured by scriptsto target a specific application. A new framework has been designed named FACTS whichcan be considered as the successor of NEAT ("New Eindhoven Architecture Toolbox") ofthe previous years. Depending on the particular angle of view the acronym can be read as "Facts: Architecture Construction for Time Constrained Systems" or as "Facts: Advanced Compiler Techniques for Scheduling." In the 266 documentation

director Design Technology for Electronics Systems Prof.Dr.-Ing. la.g. Jess ES first case the emphasis is on the constraint analysis as a new powerful tool for scheduling. The second interpretation points towards the application, which is code optimization for VLIW processors ("Very Long Instruction Word"). The techniques address in particular loop pipelining and register binding. FACTS is positively received both by the designers of media chips and the TRIMEDIA team within Philips Research. Anotherbranch ofactivity is the development ofapplications for media processors. This is undertaken to obtain more adequate familiarity with those applications. In 1998 for instance we developed 3D-graphics models for the TRIMEDIA processor. Logic and physical design Background In the area of logic design the requirements originating from the evolution of fabrication technology stimulated two major new lines of research world-wide, which in a way are complementing each other. The first line of thought develops along the hypothesis that the automatic assembly of logic blocks will stagnate at a level of, say, 50 000 logic gates. Assuming future chips to contain in the order of 100 million gates the assembly of such larger compounds of logic on the level of coarser granulation will consequently have to manipulate around 2000 of those blocks. On this level new sophisticated methods of wire-planning and buffering are under development aiming at controlling the performance degradation of the interconnect in future technologies. Following this concept UC Berkeley has set up a large project involving many other universities (among them Delft University!) and the major players of the US computer industry. The second line of thought assumes that research will succeed to provide design tools capable of assembling much larger logic blocks of, say, in the order of one million gates. Consequently the assembly oflarger chips will have to handle only about one hundred ofthose blocks at a level ofcoarser granulation. The crucial point is of course the solution of the first portion of this program. Currently a Dutch group of five former Ph.D.-students (three from the Design Technology chair at the TUE and two from Delft University) at work at a Silicon valley start-up called "MAGMA Design Automation" attempts to develop a technology being able to synthesize one-million-gate logic blocks. The company will demonstrate their product publicly at the occasion of the 1999 Design Automation Conference. The MAGMA technology (if successful) may be ofgreat significance for the Dutch electronic industry. Because ofthe strong bias towards consumer electronics and telecommunications the chip architectures will on a large scale use the concept of so-called "embeddable core processors." Those processors will be predominantly of a size between 250 000 and one million gate-equivalents. Usually it will not be possible to port crafted footprints of those cores over various fabrication technologies. This is also not viable for a series of successive generations of fabrication technologies even within a single company. The MAGMA-product (ifsuccessful) would allow to port netlists (described in, say, VHDL) ofthe cores into various processing environments and to generate their footprint optimally in one piece matched to the fabrication process. In contrast the alternate technology would force the designer to partition the netlist into some twenty blocks, generate the blocks and synthesize the compound by an alternate coarse grain technology. This would create overhead in the design flow and increase the time to market - a consequence detrimental to the economic position of the consumer industry. 12 ES Our contribution It should be mentioned that many of the ideas behind the MAGMA technology emerged from research performed at the Design Technology chair at the TUE. The product will show traces ofthe "Gate Array documentation 267

director Design Technology for Electronics Systems Prof.Dr.-Ing. J.A.G. Jess ES System" (GAS) developed by us under European Community contracts from 1985 onwards. But also results from the IOP-IC program from the Dutch Ministry of Economic Affairs concerning the socalled "regularity extraction" can be retrieved in this technology. The product hinges on an ingenious interleaving of layout- and logic design to control timing and power. In 1998 we have contractually cooperated with MAGMA on various aspects ofthe technology. We also sold a license ofthe NEAT-system to MAGMA. Our further contributions to the area of logic design are as well inspired by our commitment towards applications in the consumer and telecommunication area. This area asks for tighter control of the performance of logic blocks (in particular with respect to power) as compared to existing techniques. Therefore we concentrated on performance modeling. One of the highlights is the application of the piecewise linear simulation technique to model the entire area/power/delay design space of a logic function. With respect to delay modeling we contributed a statistical estimation method. This method is analytical (and therefore very economical) in contrast to earlier methods requiring Monte Carlo simulations. In view of the importance of power for portable products we intensified our efforts referring to power modeling and -optimization. Power consumption is to a large extent a question of IC technology. The logic designer is confined to controllingthe switching activity ofthe logic circuits. There are essentially three approaches to do that: (-) remove redundant transitions in synchronous circuits; (-) develop and optimize asynchronous circuit technologies; (-) develop techniques of gate- and transistor sizing. We went along all three ways. For synchronous circuits we developed a method of automatically removing redundant clock transitions, which is now a fixed constituent of the design environment at PhilipsResearch. With respect to asynchronous circuits we developed a complete theory for the synthesis of two level burst mode finite state automata, thus closing a gap of almost twenty years in evolution between synchronous and asynchronous techniques. In the area ofsizing we pioneered many techniques based on integer linear programming both for power modeling and optimization. A specific result of recent origin is the identification ofthe input vector pairofa combinational circuit yielding the transition burning the maximum power. Finally two other fields of activity should be mentioned being related to testing and validation. With respect to testing we pioneered the modeling of technology-induced faults like shorts and line-opens caused by spot defects. The significance of this subject has been underestimated quite generally by the industry and a change seems about to happen. Alternately we have created a lot of new techniques for the formal verification of synchronous finite state machines. Those techniques are now in regular use in systems like YATC at Philips Research, VERITY at IBM Yorktown, in the theorem proving systems of Stanford Research Institute and in the MAGMA technology. 10. development 12 ES The future of our research is firmly established on a thorough analysis of the long- and medium-term trends recognizable in the area of the micro-electronic fabrication technology. Those are documented in the programs developed by the industry and the governmental institutions. We have influenced the making of those programs for instance by contributing to the "Design Technology Roadmap" authored by the "European Design and AutomationAssociation" (EDAA) in 1998 with support from the European Commission. We believe we have identified the most urgent bottlenecks in the design technology of tomorrow relevant to the European and specifically to the Dutch industry. Therefore the development of our research is expected to exhibit a high degree ofcontinuity. Otherevents like the recent establishment of the EESI (where the Design Technology chair was one of the primary initiators and contributed the major lines of development -the "ontwikkelingsplan in hoofdlijnen") point into the same direction. 268 documentation

director Eindhoven University of Technology (TUB) Design Technology for Electronics Systems Prof.Dr.-Ing. J.A.G. Jess ES In addition this is underlined by the programs like PROGRESS, a program established by the Dutch government meant to stimulate research in the area of embedded systems. In this program the Design Technology chair initiated a project concerning the concept of a "media server" for the home. The principle is to design an architecture that uses the ability of the IC fabrication technology to concentrate a large amount of functionality in one chip for a moderate price. Also ourcontributions to the COBRA "research school" (comprising our research on logic and physical design) deserve to be mentioned. In 1998 COBRA was recognized as the second best in the national competition of "top research schools" for its program in the area of photonics. As a result COBRA received an extra financial injection in the order of 50 million Dfl. Recently Philips Semiconductors (Nijmegen) initiated a major effort in the area of "Design for Manufacturing." This subject connects to our earlier research in (technology induced) defect- and fault modeling. Philips Semiconductors wants the Design Technology chair to become a "center of knowledge" in this domain and is ready to render financial support towards this objective. For 1999 we plan a sabbatical visit of Prof. W. Maly (Carnegie Mellon University, Pittsburgh, USA), recognized as the primary researcher in this domain throughout the world. It is intended to work out a long term research program together with Prof. Maly. The current holder of the Design Technology chair is bound to retire in May 2000. Also various senior researchers have left the university for alternate positions in the research laboratories in the industry. The faculty of Electrical Engineering of Eindhoven University has nevertheless initiated major steps to continue the Design Technology program in full strength. At this time action has been taken to appoint the successor on the chair well before the current holder leaves. There are also facilities to replace the researchers having left. Two of the younger scientists of the group have already achieved international recognition as advanced researchers. 11. Societal/technological relevance There is little doubt among experts that information technology is the primary driver of the industrial and economic evolution in the industrialized countries. This is indicated by a wealth of governmental documents in all of these nations and the European Commission (and also, for as much as they are available, documents originating from the industry). For example the world market of micro electronic components (which is only a small part ofthe total ofthe market for information technology) is expected to grow from 120 Billion US$ in 1995 to 200 Billion US$ in the year 2000. The European market of information and communication products and services grew in 1995 with 8.5% and 1996 with 8.7% to then reach a volume of 630 Billion Dfl. For the first time in history this growth is faster than in Japan and USA and goes on the account of telecommunications.! All these technologies bootstrap on the semiconductor technology evolving according to Moore's Law. The alarming observation is that the efficiency ofthe design activity lacks behind this growth. While the US computer industry tries to make up for this lack by planning way in advance, the European industry (hinging mainly on consumer- and communication products) cannot really look ahead in the same way. The latter markets are fuzzy and difficult to control and require flexibility and speed. To obtain a lead position the efficiency of the design flow is the deciding factor. Failing to be able to actually exploit the 12 future semiconductor technology may result in a major economic disaster for Europe. ES Design technology is in principle capable to streamline design flows and enhance their efficiency. Fig. 1 below (taken from the Ph.D.-thesis of la.a.m. van den Hurk, 1996) indicates the influence on the design efficiency when a commercial tool for automatic logic design was introduced in the design flow 1Aarts, E.H.L.; Jess, 1.A.G.: EESI ontwikkelingsplan in hoofdiijnen.

The efficiency is measured by averaging over the performance ofthe team during the design of I 3 different products between January 1991 and July 1996.,/ Descrambler-CO / QJ;>MC /a I I I 1---1 I Jan-91 Aug-91 F.b-9Z S.pt-92 Apr-93 Oct-93 May-94 Nov-94 Jun-95 D.c-95 Jul-96 - - - - - - - Auto-layout Auto-layout & Logic Synth Fig. 1: Average productivity ofan individual designer While there is a discontinuity in efficiency at the instance of the introduction of the auto-logic tools (indicating the necessity for the designers to get used to the new tools) the design efficiency rises more steeply after this instance. To actually create the necessary grow in efficiency this process must be repeated a number of times in consecutively shorter intervals with more advanced flows and tools addressing systems issues. It is doubtful that the US design automation industry will provide those tools as it is strongly guided by US economic interests pointing towards quite different objectives. Therefore there rests a particular challenge with the European research groups to provide the electronic companies with the right means to compete. Our group has shown that this can be done by strategic alliances with the respective companies and the governments. Unfortunately the US-way with start-ups is up to now not flourishing in Europe. There is a complex multitude of reasons which make this tendency unlikely to be reversed soon. It is therefore important to maintain or even increase the volume ofresearch in this area and strengthen the basis ofthe strategic alliances with the industry. Flexible frameworks like FACTS establish paradigms fitting those alliances very well. FACTS is structured to implement design flows by scripts in the way it is explained in the last sentence of section 8. 12. Other indicators of quality and reputation Drjr. M.R.C.M.

Continuous (including optical) as well as discrete (mostly digital) and one-dimensional as well as higher dimensional signals and systems are taken into consideration. Signal description may be in deterministic or stochastic terms. The programme is characterised by: its emphasis on the fundamentals of signal processing in terms of mathematical and physical concepts, methods and models, and its emphasis on applications, in which the design, the simulation and the experimentation with (real-time) signal-processing systems playa central role. With respect to the fundamentals of signal processing, modern developments are constantly requiring new mathematical and theoretical-physical methods and models both for the description of a system as well as for the description ofthe signals that are processed by this system. With respect to applications of signal processing, research in this field will be concentrated more and more on the real-time aspects that are relevant in designing new signal-processing systems, which will continue to become larger, faster, and more complex. With these considerations in mind, the Signal Processing group has formulated the following mission: to strengthen and enlarge the fundamentals of this field of science; to disseminate knowledge in the field of signal processing; to establish a profound basis for interdisciplinary research and technology activities, for which, very often, the results from signal processing form a set of indispensable scientific tools; to contribute to the improvement of existing and the development of new signal-processing systems, in accordance with modern developments in the field of signal processing and with requirements from industry and society. Many practical signals are non-stationary while most practical systems are time-varying. For this reason the Signal Processing programme is focussed on the following subjects: 13 ESP Mixed signal descriptions: Although time signals are traditionally represented in a pure time domain or in a pure frequency domain, such signals might as well be represented in a mixed time-frequency domain. This simultaneous time-frequency representation is only one of many mixed signal descriptions, with the help of which feature extraction and signal interpretation might be simplified. Moreover, the concept ofmixed signal descriptions need not be restricted to time signals, but can be extended to more general and higher-dimensional signals, as well. Signal 286 documentation

director Eindhoven University of Technology (TUB) Signal Processing Drjr. P.c.W. Sommen ESP descriptions which have been considered are those by means ofa local frequency spectrum, using the Gabor transform on the one hand and the Wigner distribution function and other representatives of Cohen's class of quadratic signal representations on the other, time-scale representations like wavelets, and general windowed transforms like the local Kautz transform. Adaptive filters: Adaptive filters are a useful alternative for fixed filter applications ifa favourable exchange between complexity, precision and convergence properties can be obtained. New algorithms have to be developed to decrease signal dependency and improve learning-rate and stability, by using block processing, deconvolution, orthogonality and time-frequency-position trade-offs. Besides this fundamental work on algorithms, emphasis in the field of applications is placed on real-time aspects when large adaptive systems, as needed in e.g. audio applications, have to be realised on digital signal processors (DSP's). Orthogonal series expansions: The objective of this subprogramme is the analysis, implementation and application of orthogonal series expansions in signal processing systems, in particular with digital means. Applications of these expansions in the field of compression, adaptive filters, system identification and signal segmentation have been considered. 9. Overview ofacademic results Mixed signal descriptions In recent years there has been a growing interest in the description of a time signal not in a pure time domain or in a pure frequency domain - by means of its Fourier transform, for instance - but in a combined time-frequency domain. Such a description is conceptually very attractive, and has been used in a rather loose way for centuries: descriptions of musical signals by means of their musical scores, description of optical signals by means of ray patterns, and description of classical phenomena in a phase space are just a few examples of such a mixed signal description. The nowadays very popular description of signals by their wavelet transform is another mixed signal representation, but then in a combined time-scale domain. Our group has concentrated its research on mixed signal descriptions to (i) the Wigner distribution function (a quadratic time-frequency description) and to (ii) Gabor's signal expansion and the windowed Fourier transform (a linear time-frequency description), with occasional excursions to wavelets. Both signal descriptions have the property ofa conceptually nice interpretation, without losing any relevant signal information. The theory ofthe Wigner distribution function was mainly applied to optical phenomena, in particular to partially coherent light and the propagation of such light through first-order optical systems (containing thin lenses and sections of free space). It has been shown that many optical phenomena used in radiometry, in geometrical optics, in matrix optics, in Gaussian optics, etc., can directly be expressed in terms of this Wigner distribution function. In particular it has been shown how an optical beam, which may be coherent or partially coherent, can be characterised by the second-order moments of its Wigner distribution function (with not only the well-known moments in space and direction, i.e. spatial frequency, but also the mixed space-direction moment) and how beam invariants (i.e. invariant under propagation through first-order optical systems) can now easily be formulated. Applying these techniques to partially coherent Gaussian beams, we were able to formulate some nice properties of the so-called twist of such beams in a very natural way. Our main research interest was in Gabor's signal expansion and the windowed Fourier transform. After the demonstration (by our group in the early eighties) ofthe unique relationship between Gabor's signal expansion and proper sampling ofthe windowed Fourier transform, many research groups have devoted 13 ESP documentation 287

director Signal Processing Dr.ir. PCW. Sommen ESP there attention to this subject. Gabor's signal expansion describes a signal as a superposition of shifted and modulated versions of a synthesis window function, where - in its original form - these versions appear on a rectangular lattice in the combined time-frequency domain and each version has its own expansion coefficient; the expansion coefficients can be determined by sampling the windowed Fourier transform (with a proper analysis window function) on this rectangular lattice. We have shown how the analysis window can be determined from the synthesis window, both in the continuous-time and the discrete-time case. Moreover, we were able to show how oversampling in the time-frequency domain (resulting in a non-unique relationship between the analysis and the synthesis window) can be exploited to find the optimal analysis window for a given synthesis window. Furthermore, we succeeded in describing other sampling geometries in the time-frequency domain as transformation of the original rectangular geometry, with a simultaneous transformation of the window functions. These techniques allowed us to formulate fast algorithms to determine Gabor's expansion coefficients, even in the case of these other (and better) sampling geometries. Adaptive filters In many audio and acoustic applications very long adaptive filters are needed. Acoustic signal paths are not only extremely complex and varying in time, but they are also not known beforehand. Long adaptive filters are realised by using efficient block processing techniques and Fast Fourier Transforms (FFT's). These methods become more efficient when larger blocks are used. However, these large blocks result in a large processing delay. By introducing partitioning concepts a good balance between efficiency, processing delay and convergence properties can be made. These partitioned block frequency domain adaptive filters bear a distinct resemblance to so-called adaptive filter banks, where each frequency band is processed separately. The time-frequency approach used in partitioned structures, however, is much more efficient. The next step in the research of audio and acoustic applications is the use of information on the (twodimensional or spatial) position of sound sources. This information can be obtained by using more than one sensor (microphone). The research on long adaptive filters in the time-frequency domain is extended to the domain of time, frequency and position. Putting it in another way, single-input singleoutput systems are extended to multi-input multi-output adaptive filters. With these so-called adaptive array structures the group has studied two audio applications, namely phantom sources and transparent communication. A phantom source can be obtained by processing an audio signal before it is sent to the loudspeaker in such a way that the auditory event is positioned at a completely different location in the listening space than the location of the physical loudspeaker. It is shown, both theoretically and by simulations, that a significant improvement in the robustness of a phantom sound source against small movements of the listener can be obtained by using constant-q (constant relative bandwidth) spectral analysis (the discrete Mellin transform) instead of the conventional Fourier transform. To meet the realtime requirement, a novel method has been introduced (using exponential sampling) to calculate this transform in real-time. It is also shown, in a demonstration setup, that this new method can also be used for other purposes such as time/pitch scaling. 13 ESP The other application aims at building a transparent audio communication system which will allow users who are in separate rooms to communicate with each other as if they were in the same room. Communication therefore will take place as naturally as possible for the user. The communication in such a transparent audio communication system, and in all hands-free audio communication systems in general, usually involves users that are at some distance from the microphones. This has a negative influence on the quality and the intelligibility of the desired speech signal because of the following four component problems. (i) Acoustical echoes: these arise from incoming loudspeaker signals reflected 288 documentation

director Signal Processing Dr.ir. P.C.W. Sommen ESP back into the microphones via the acoustics of the room. (ii) Background noise: this can include noise from e.g. ventilators, air-conditioning systems, or computers. (iii) Undesired speech signals: these originate from speakers other than the desired speaker. (iv) Reverberation: this arises because not only the desired direct speech signal is picked up by the microphones, but also the reflections from objects and walls in the room. All four problems are related to the acoustics of the room in one way or another. Due to the continuously changing nature of these acoustics, an array of large adaptive filters is used. A new signal separation algorithm has been introduced in order to tackle the first three problems mentioned. First simulation results and a demonstration setup show positive results. A joint patent proposal with Philips Research Laboratories is submitted, describing an efficient way to decorrelate the input signals of an adaptive array. Looking at the fundamentals ofadaptive signal processing, the basic theory of adaptive filters, which is based on the LMS algorithm, has been put to the question. The current textbooks develop this theory on the basis of the so-called independence assumption which is not only unplausible in practice but, in almost all cases, even a theoretical impossibility. The key question in this research is whether a theory can be developed that does not invoke the independence assumption and, given that, if such a theory can be presented with a minimum of mathematical sophistication in view of teaching purposes. It has been shown that by using a series expansion in terms of the adaptive constant, good approximative descriptions ofthe LMS algorithm can be derived. Furthermore, it has been shown that a description by wave-equations allows an elegant approximative treatment ofthe behaviour of long tapped-delay-lines. The misadjustment, initial learning and the stability condition have been derived. Orthogonal series expansions Orthogonal series expansion of signals or system descriptions has been applied to several practical problems. Often, these series are ofinfinite length and, in practice, have to be truncated. In that case, one is interested in a compact, approximate representation of the signal by some adequate series expansion. This means that, first of all, the basis functions have in some way to be matched to the signal that is to be expanded. Furthermore, many series expansions have one or more free parameters. One ofthe major themes has been to exploit this freedom to obtain compact orthogonal series expansions. In particular, it has been shown that for series expansions associated to orthogonal polynomials, there exist simple procedures (avoiding search algorithms) to establish the parameters in these series, where the optimality of the parameters is based upon a compaction criterion. Next to the use of orthogonal functions for purposes of compaction, they can also be used in adaptive filters andintheareaofsystemidentification. TheuseofadaptiveLaguerrefilters, Kautzfilters, adaptive line enhancers and model reduction by orthogonalised exponential functions and sequences has been considered. Furthermore, a theory concerning sliding-window orthogonal representations has been developed. In many ways, this can be seen as a generalisation of the concept of the short-time Fourier transformation where the Fourier transformation is replaced by a rather arbitrary orthogonal transformation. It has been shown that inparticularlocal Kautztransformationsyieldboth simpleanalysisand synthesisfilter banks. At the moment, the use of orthogonal projections for signal segmentation is studied. Such an approach has potential in both video and audio applications. So far it has been shown that the use of orthogonal projections in the more dimensional case leads to requirements which are, in our view, too restrictive for general application. Therefore, the focus has currently been put on applications in the field ofaudio and speech processing. 13 ESP documentation 289

Due to a reshuffling of some activitiesin the Faculty, the SignalProcessinggrouphas merged with themedical Electrical Engineering group to form one new research group (one chair) that is part of the division of Signals, Systems, Measurement and Control. The application procedure for a new professor has been started and the appointment of a new chair can be expected in 1999. Without neglecting algorithm design, the Signal Processing group will put a stronger emphasis in its research on (real-time) implementations of signal-processing algorithms on DSP systems and other full-custom architectures, and on adaptations of such algorithms to requirements that arise from implementations on chip level. The present division of research into roughly 2/3 fundamental and 1/3 application-oriented is shifting in the direction of more application-oriented research. With this shift it is expected that the low external 2G and 3G fundings can be enlarged. The research on mixed signal descriptions will be extended to the two-dimensional case; it is evident that in this case the need for efficient algorithms is much stronger. The connection between Gabor's signal expansion, wavelets, subband-coding, and related topics on the one hand, and the practical implementation of the corresponding algorithms by means of filter banks on the other hand, will be exploited. Research on the Wigner distribution function as an elegant means to describe the behaviour of partially coherent light beams will continue. New projects are defined around blind signal separation subjects. In the first instance, this knowledge will be used in order to develop a transparent communication system. At a later stage, separated audio will be coupled to separated video objects. These two research subjects, Le. (blind) signal separation and audio/video interaction, will be used as a new vehicle for the group to develop new efficient algorithms. When applying this research to audio signals, it is obvious that the algorithm development is closely related to such subjects as perception and coding. In order to gain insight into the ultimate result of the algorithm in real-time, experimental tests are needed. For this reason the group is building its own listening room at this moment. Finally, the group is convinced that these newly developed algorithms can also be used in other application areas such as biomedical engineering or communications. This will also be a subject of new research. 11. Societal/technological relevance Since many practical signals are non-stationary and most practical systems are time-varying, mixed signal descriptions and adaptive filtering algorithms, together with local orthogonal series expansions, find applications in many practical situations. Apart from the development of fundamental knowledge in these fields, our group currently applies these techniques to the development ofphantom sources and a transparent audio communication system. 13 ESP The developed phantom sources are ofgreat interest at the moment because oftheir potential application in television, multimedia computers, portable audio equipment, digital versatile disk (DVD), home theatre, flight control and game machines. By using two adaptive filters the system topology can be made similar to that of a two-point Active Noise Cancellation (ANC) system. Furthermore this ANC knowledge is used in order to realise the so-called Multi-Point Acoustic Noise Cancelling (MPANC) project. In this project the group worked together with a small company (Prodrive) in order to realise a demonstration setup of an MPANC system. Transparent audio communication, but more in general knowledge of (blind) signal separation, can be used for the improvement of quality of (existing) audio conferencing systems, car telephony systems, 290 documentation

Faculty Faculty ofelectrical Engineering Discipline protocol Appendix B: Discipline protocol Electrical Engineering Introduction This research assessment covers the discipline of Electrical Engineering. The aim of research and education in the field of Electrical Engineering is to educate academic engineers and designers, to perform fundamental and application-oriented scientific research at an international level and to transfer knowledge; for the latter a good co-operation with industry is of great importance. The main aims of the assessment are, in concordance with the Protocol 1998, the improvement of the quality ofthe individual research programmes and the provision of information for the accountability of the research carried out. The assessment will be placed in the context of the activities of the faculty and it will give an appraisal of the general features of the scientific area covered in this assessment. Required expertise of committee members Besides a positive attitude towards fundamental and applied aspects ofresearch and the multidisciplinary character ofthe discipline ofelectrical Engineering, the following expertise is required for the members of the review committee: Information technology Micro-electronics Power engineering Sensors and actuators Signals and systems Telecommunications This list is alphabetically arranged and does not show priorities. One of the application areas of electrical engineering is biomedical engineering. Therefore it would be appreciated if one of the committee members has also expertise in biomedical engineering. The committee will consist of seven members, the chair included. Procedural plan ofthe committee The committee is independent and will determine its own method of working, within the framework of Protocol 1998 and this Discipline protocol. In this respect, the following points are of importance: The committee will hold site visits. Sufficient time has to be spent on this part of the procedure (at least one day for each separate faculty). Separate research groups should be visited by as many (if not all) committee members as possible. The committee members will be able to meet the responsible boards for research management and policy within the faculty, programme directors and other participants in the research programmes (e.g. PhD students). In preparation of the meetings the committee will give subjects and the goal of the discussions that will be held with the faculty board and the separate groups during the site visits. Assessment standard According to the types of publications which are mentioned in "Assessment of Research Quality: Protocol 1998," Utrecht, VSNU, 1998, Appendix 4 (pp. 41-44) the following categories are taken into account: Discipline protocol 309

Faculty Faculty of Electrical Engineering Discipline protocol PhD theses Academic publications divided in journal articles and other academic publications. For the journal articles a distinction is made in refereed and non-refereed articles. For other academic publications, a distinction is made in books, book chapters and conference-proceedings & important abstracts. Twaio-reports can be added as a category. Professional publications Patents The category 'Realised designs' will be mentioned in Section C (Documentation per programme) under paragraph 12: 'Other indicators of quality and reputation.' In accordance to these categories the table concerning research output (see ''Assessment of Research Quality: Protocol 1998," Utrecht, VSNU, 1998, Appendix 3, Section C, 6. Research output, p. 38) shall be changed. A list will be added of PhD theses, academic publications, twaio reports and patents. For the output category 'professional publications'the number of the publications will suffice, however, ifdesired,three professional 'key' publications may be added. The distinction between refereed and non-refereed journal articles will be made on the basis of a list prepared by the three faculties. This list is added in an appendix. Further relevant information for this assessment In order to evaluate the impact of the research output a bibliometrical analysis will be performed. This analysis will be performed by CWTS, Leiden University and will take into account the publications of those persons participating in the research programmes present at 31/12/98. A list of names will be compiled by the faculties and needs to be available as soon as the study will be commissioned to CWTS. In principle, the list will contain the smallest number ofsenior researchers as possible that guarantees the largest coverage of academic publications. To allow for the possibility that others than senior researchers publish independently, programme directors may add such publications produced in their group. An analysis will be made of the publication and citation behaviour for the area in The Netherlands, Europe and worldwide. In a recent document (ST-1995 09 06-6/2) the Dutch Technology Foundation STW has stated that for technical sciences the results ofa bibliometric analysis should never be the sole instrument for evaluation of scientific research, and that such results should only be carefully used by experts in the field. The faculties ofelectrical Engineering support this view and they trust that, ifthe Review Committee (which will use the bibliometric analysis as one of its instruments for assessment) wishes to present bibliometric results in its final Report in one way or another, it will do so with great care. Level of aggregation A research programme is defined as "a coherent set of research activities having a common mission and being the work of a group of people who generally work together on a daily basis." For the purpose of this evaluation this will normally be the activities of a group directed by a chair (leerstoel). members The academic staff is subdivided into the following ranks: 310 Discipline protocol

Faculty Faculty ofelectrical Engineering Discipline protocol professors (hgl) associate professors (uhd) assistant professors (ud) fellows and others who have attained a PhD Research input of academic staff In the table concerning research input all junior researchers in any stadium of promotion are concerned as AIO/OIOs; the programme members as mentioned above are concerned as others. In this assessment the input of AIOs etc, as well as postdocs will be standardised to 0.8 fte, UDs and UHDs to a maxium of0.6 fte and professors to a maximum of0.4 fte.
