9 ANNUAL REPORT 2012 KEY IT INDICATORS 1. INTRODUCTION 1.1 History Instituto de Telecomunicações (it) is a private, not-for-profit organisation, an association of eight institutions with research and development in the field of Telecommunications: Instituto Superior Técnico (IST); Universidade de Aveiro (UA); Universidade de Coimbra (UC); Portugal Telecom Inovação, (PTIn) Nokia Siemens Networks S.A Universidade da Beira Interior (UBI) Universidade do Porto (UP) ISCTE - Instituto Universitário de Lisboa (ISCTE-IUL). it is organised around three sites: Aveiro, in the University Campus, Coimbra, in Site II of the University of Coimbra, Lisbon, in Instituto Superior Técnico, and four branches: Leiria, in the Escola Superior de Tecnologia e Gestão of the Leiria Polytechnic (IPL), Covilhã, in the University of Beira Interior (UBI), Porto, shared by the Faculty of Engineering (FEUP) and the Faculty of Sciences of the University of Porto (FCUP), Lisboa, in ISCTE - Instituto Universitário de Lisboa (ISCTE-IUL). Setting up of it was the result of a 1.5 billion escudos (about 7.5 million Euros) grant from Programme CIENCIA, through three contracts signed in This investment enabled new infrastructures to be built and research laboratories to be equipped at each site. Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in Since 1993, it activities proceed regularly. it bylaws were first approved in 1992, modified in 1997, 2003 and New Site bylaws deriving from it bylaws were approved and implemented in

10 ANNUAL REPORT 2012 KEY IT INDICATORS Key developments in 2012 are highlighted ahead. Details are included in the sections dealing with each of the research areas. 1.2 Management it is managed by a Board of Directors, elected by the General Assembly, and by Site Management Boards, which include the Site members of the Board of Directors. Site Management Boards enjoy ample freedom to deal with current affairs and usually meet weekly. The Board of Directors meets at least once a month. it scientific activities are overseen by the Scientific Board, which includes all it researchers holding a Ph.D. degree. The Scientific Board meets in Plenary or in Committees, both permanent and temporary. There are two permanent committees: the Science and Technology Committee and the Research Group Coordination Committee. it Work Plan and the Annual Report are discussed with the Advisory Committee, formed by three independent experts in the field of telecommunications (Dr. Roland Huber, Prof. Sir John O Reilly and Prof. Martin Tomlinson) acting in a personal capacity, and together with the Accounts Report (after legal certification) are subsequently submitted to the General Assembly for approval. The General Assembly met formally twice in The first meeting was held on July 27th, in the Meeting Room of the Lisbon site, to discuss and approve the 2011 Annual Report and Accounts, to analyse the membership request from Instituto Politécnico de Leiria, Instituto Superior de Engenharia de Lisboa and the Universidade do Algarve, to discuss the possibility of opening delegations at the Instituto Superior de Engenharia de Lisboa and the Universidade do Algarve and to elect the members of the Board of Directors for the period The second meeting took place on December 12th, in the Meeting Room of the Rectorate of Universidade da Beira Interior, to discuss and approve the Work Plan and Budget for The Research Group Coordination Committee also met twice during On the first meeting, held on March 20th, at it auditorium at the Aveiro site, the Draft Proposal of the 2011 Annual Report and the proposals for opening delegations at Instituto Superior de Engenharia de Lisboa and the Universidade do Algarve were discussed and received a favourable opinion. On the second meeting, held on December 17th, in meeting room 2 of IST Congress Center Hotel (Coimbra), the Work Plan and Budget for 2012 were discussed and received a favourable 10

11 ANNUAL REPORT 2012 KEY IT INDICATORS opinion. The first year reports of the first batch of internal projects were presented and discussed. The Advisory Board visited it (Lisbon, Coimbra, Aveiro and Porto) on the 11th and 12th of January Researchers from Covilhã and Leiria were interviewed in Coimbra. The report (included in Annex) is highly positive in what regards it scientific achievements and recommends more focus on technology transfer. 1.3 Highlights of 2012 Scientific output In spite of the very serious reduction of funding, mainly from FCT strategic funding, it scientific output in 2012 reached an all time high (the apparent contradiction of scientific output increase versus reduction of funding is explained ahead): 25 books; 53 book chapters; 335 papers in international refereed scientific journals; 479 papers in refereed conferences, with published proceedings; 9 patent filed. Foreseen output for 2012 was 30 books and book chapters; 200 papers in international refereed scientific journals; 400 papers in refereed conferences, with published proceedings. Achieved scientific output exceeded by far our forecast, in all areas, and became a new record. Fostering advanced education also reached an all time high: 42 PhD theses, submitted and approved, 207 MSc theses, submitted and approved, where the estimated numbers for 2012 were: 30 PhD theses, submitted and approved, 200 MSc theses, submitted and approved. 11

12 ANNUAL REPORT 2012 KEY IT INDICATORS It is worth noting that, for the first time, the number of concluded PhD theses approaches one fourth of the number of PhD students, that is, the duration of the thesis work approaches four years. it researchers received the following distinctions: Silva, J.

Araújo; "Contribution of Web Services to Improve Pain Diaries Experience ", Best Paper Award of The 2012 IAENG International Conference on Internet Computing and Web Services - IMECS2012, The number of scholarships decreased significantly in 2012 with respect to 2011, due to a largely reduced FCT strategic funding (as explained in more detail below), that is: 181 Ph.D. scholarships, funded by FCT; 13

14 ANNUAL REPORT 2012 KEY IT INDICATORS 209 other scholarships, funded by it, as follows: 32 Ph.D scholarships 45 B.Sc. scholarships 75 M.Sc. scholarships 24 post-phd scholarships 1 technician scholarship 4 Integration in R&D fellowships, 21 R&D starting grants 2 Management of Science and Technology fellowships, 5 mobility fellowships associated with the CMU-Portugal Program. During 2012, 140 nationally funded and 29 internationally funded projects were active, as shown in section 2.2. It is particularly noteworthy the fact that on the 31 st of December it was involved in 21 running FP7 projects (running and selected for funding) in addition to other 3 projects, where there was involvement of some it researchers from the Lisbon site. IT funding In the past few years, FCT strategic funding i.e. funding for the IT - Laboratório Associado contract, was never timely. It suffices to say that funding for 2010, about 2.2 M, was received in January 2011 and was executed (98 % rate) until December 31st Strategic funding for obeyed new rules: an upfront payment of 20 % of the approved budget (ie 1.2 M ), followed by the reimbursement of 80 % of the accepted expenses. The 20 % share was received in two instalments (April and August 2011) but its executing only started in January 2012, since during 2011 it was running with the 2010 strategic funding. In part, this was the reason for the observed low impact in 2012 of the funding shortage on it s scientific output. As foreseen right in October 2011, this new payment method was extremely damaging because FCT was never able to process reimbursements in less than three months. In addition the number of payment requests increased dramatically from once a year up to twenty or more (for the IT Laboratório Associado contract). In fact, the delay in reimbursements exceeded our worse expectations. Not only it reached (in cases) up to 6 months but, worse 14

15 ANNUAL REPORT 2012 KEY IT INDICATORS still, many expenses were deemed to be non eligible on the first submission, forcing it to resubmit again and again the same expenses, with renewed justifications. At the time of writing, it has executed the whole advanced payment and submitted claims for 1011 k and received 247 k (instead of 809 k ). The remaining claims should be submitted until March 31st 2013 but it is still unclear if the remaining reimbursements will ever be made. Since about 50% of the reimbursements were paid in December 24th, 2012, it was not feasible to use these sums for payments in FCT demanded that funding should be used until December 31st 2012, contrary to previous practice and general expectations, delivered a very serious blow to strategic funding. At present it is unclear if reimbursements, both paid late and due but not paid in 2012 may be used for eligible expenses during To compound things, in July 2012 FCT took the unilateral decision that mission grants could no longer be accepted as eligible, even if these grants are defined in it grant regulation approved by FCT. This decision of non-eligibility of already made mission expenses, (because in this instance FCT had made up 90% advance payments), prevented these projects from closing and thus prevented it from getting the final payment (10%). Finally in November 2012, FCT agreed to accept eligibility of mission grant expenses up to December 31st 2012 subject to some minor changes in the submission of such expenses. New rules and procedures will apply from January 2013 onwards, for mission funding. To complete the bleak picture, it should be mentioned that from August 12th, 2012, it must comply with the rules of the Code of Public Contracts. The resulting increased bureaucracy is appalling to say the least and already has negative impact in it activity, not to mention the increase in administrative staff and bureaucratic costs. From the above it is quite clear that it management was cautious and did not embark in borrowing money to execute the contract value (3 M for 2012) since FCT never guarantied that reimbursements were to be paid. This cautious approach earned it a serious (40%) decrease in 2013 strategic funding, which was (up to now) calculated on the basis of the amounts executed in

Project MONIT, ( was actively engaged in promoting and diffusing know how on electromagnetic radiation and mobile communications. Occasionally, through this project, it offers two week training in the measurement of electromagnetic radiation. Sponsored by CIENCIA VIVA, it organized a one-week hands-on introductory course on telecommunications for 10th and 11th grade high school pupils with 15 enthusiastic participants and an open-lab two hour session for a similar audience. Also in cooperation with IST, it organized visits and demonstrations for high school pupils, involving about 1000 pupils (in 2012). During 2012, it commemorated its 20th aniversary with half-day seminars, visits, exhibitions and demonstrations in its 3 sites and 4 delegations, which all in all joined more than 600 participants. During 2012 it reinitiated a regular publication of its monthly newsletter, which is distributed electronically to all researchers and PhD students and also started to be present in social networks (Facebook, YouTube and Flickr). Finally it should be stressed that in 2012 it researchers created two new companies (Veniam, Streambolic). Streambolic earned the grand prize at the 8th BES Concurso Nacional de Inovação and Veniam won the 3rd Building Global Innovators Venture Competition ISCTE-IUL MIT. 19

20 ANNUAL REPORT 2012 KEY IT INDICATORS 2. KEY IT INDICATORS Human Resources In December 2012 it human resources included 720 people distributed as follows: 262 researchers; 223 PhD students; 206 grantees; 12 technical; 17 administrative. All researchers but 2, hold a PhD degree. The distribution of all human resources between the three sites is represented graphically in Figure 2.1. It is obvious from this figure that the ratios between PhD students and researchers and between grantees and researchers is much higher in Aveiro than in Lisbon a fact that is partly explained by the much higher involvement of Aveiro in FP7 projects. 20

21 ANNUAL REPORT 2012 KEY IT INDICATORS Figure 2.1: Distribution of it human resources between the three sites The distribution of researchers and PhD students between sites and delegations is shown in Figure 2.2. This figure shows, more than the previous one, the lower proportion of PhD students in relation to the number of researchers in the IST site and, even more seriously, in the ISCTE branch. 21

22 ANNUAL REPORT 2012 KEY IT INDICATORS Figure 2.2: Distribution of itresearchers and PhD students among associated universities Unfortunately our accounting systems only provides site information for grantees and thus it is not yet possible to have a more detailed picture of grantees distribution. As a result of the application it quality policy, out from the 260 researchers holding a PhD Degree, 50 were excluded from FCT basic funding, and 12 had a 25 % reduction of FCT basic funding. As a result, in the first semester of 2012 it has eligible researchers. The distribution of it technical and administrative staff is shown on Figure 2.3 and

The scientific productivity in 2012 was 1.75 journal papers per eligible researcher or, counting each book, bookchapter and journal paper as one publication, 2.15 publications per eligible researcher. It is interesting to compare in Fig 2.5 to Fig the distribution of the number of researchers per site and delegation with the number of number of published works (papers in international journals and communications to refereed conferences). One should note that in these graphics the sum of the number of publications per site and/or delegation is higher than the number of publications for it because a significant number of publications (about 30%) are authored by researchers from more than one site and/or delegation. This fact in itself is an important indicator that it is increasingly operating as a unity rather than as a collection of research units. In the following figures, it and CIENCIA paid researchers and their publications are not included. 27

32 ANNUAL REPORT 2012 KEY IT INDICATORS Even if Figures 2.7 to 2.14 are self explanatory, it is interesting to remark that at the level of papers in journals, site distribution follows very closely research distribution. Differences are slight at the level of communications to conferences and considerable at the number of patents where the importance of Porto shines. Going into delegations, some differences are rather more striking, particularly at the level of papers in journals, which could not be seen at the site level. Networks and Sinergies it management has been trying hard to improve networking not only between its researchers but also with external researchers. Using social network analysis software tool (NodeXL) and it databse of journal publications in 2012 with kwnon ISI WoS impact factor, figure 2.13 was produced representing it co-authorship network in In this figure each researcher is represented by a disk whose colour indicates the researcher scientific aera according to the following code: Red Wireless Communications, Blue Optical Communicatons, Orange Networks and Multimedia, Green Basic Science and Enabling Technologies. The disk diameter is proporcional to the member of connections originated by each mode. The existence of a paper authored by two or more researchers is represented by a line between the modes involved. The networking strength in 2012 is apparent in figure 2.13 and may be better appreciated in figure 2.14 that was obtained using it database of ISI journal papers for the period 2007 to Although most connections involve researchers of the same scientific area, there is a significant number of connections between researchers of different scientific areas, a clear indicator of the synergies it is fostering. Connections with external authors are not shown for coarity. In both figures the small disks shown at the bottom left represent authors with 2 or less connections. 32

44 ANNUAL REPORT 2012 WIRELESS COMMUNICATIONS Summary of Research Achievements Contributing groups Antennas and Propagation - Lx Antennas and Propagation - Co Antennas and Propagation - Lr Mobile Networks Av Mobile Systems - Av Radio Systems - Av Radio Systems - Lx Wireless Circuits Av Wireless Circuits - Lx Antenna Analysis and Design Work on antennas has been focused on a few main topics: antennas for RFID and UWB systems and antennas for microwave and mm-wave applications with emphasis on antennas for Ka-band satellite communications and small antennas for indoor applications RFID and UWB Antenas Work continued on the design of UHF RFID tag antennas and UWB antennas for indoor personal communications and for indoor localization. New low-cost antennas for UWB indoor localization, including hybrid antennas appropriate for simultaneous RFID identification and UWB localization have been designed. A system demonstrator and new algorithms for indoor localization enhancement were developed. Work continued also on near-field reader antennas for UHF-RFID confined detection applications, including mirror embedded transparent antennas.

45 ANNUAL REPORT 2012 WIRELESS COMMUNICATIONS Low cost UHF RFID tag antennas for near-body applications, including interworking with body-implantable antennas have been designed, fabricated and experimentally tested. Emerging low-cost tag fabrication techniques based on ink-jet printed have been explored. A source-stirred UWB radiation efficiency measurement method was developed and results were compared with reverberation chamber measurements and computer simulations. The method provided a simple cavity-based approach to UWB antenna efficiency measurement. An efficient and simple UWB model of a human limb was introduced for antenna simulations. The adequacy of the model was confirmed by antenna measurements and an antenna prototype for wearable systems was developed. UWB matching resilience of dielectric loaded antennas was confirmed and improved through measurements and by using a simple and accurate human limb model Satellite related antennas Development of a new concept of low-cost antenna for GPS-based positioning calibration for precision demanding applications like aircraft instrument landing systems in airports; New developments on low-cost dielectric lens-based mechanical steerable beam antenna for Ka ground terminal satellite services; Design of multi-beam metamaterial-based Fabry-Perot antennas for Ka satellite deck installation; Design and test of microstrip patch antenna elements and arrays for Ka band space applications;

46 ANNUAL REPORT 2012 WIRELESS COMMUNICATIONS Other antenna related topics Other lines of research have been pursued including: Design and test of an implantable compact antenna to be applied under the human skin for medical applications; Work was also put in the designing of special antenna structures for vehicular communications, among vehicles and between vehicles and infrastructures based on wireless communication technology known as dedicated short range communications (DSRC). DSRC are in great development with the aim of reducing traffic problems and improving road safety. The study addressed both the development of an antenna solution for the mobile module, usually named On-Board Unit (OBU) and the design of an antenna for the RSU (Road Side Unit) Circuits and systems for wireless communications During 2012 the work devoted to wireless circuits and systems was mainly concentrated in the design of flexible radio circuits and systems for several applications, including: Software Defined Radio systems, Wireless Power Transmission, Nonlinear Models and Characterization for high speed digital buffers, Circuits for Dedicated Short Range Communications Agile Transmitters New reconfigurable ΣΔ-based transmitter architecture supporting multichannel multimode data transmission has been designed and validated. The high flexibility of this architecture enables a data transmission scenario where the frequencies of the carriers and the spectral masks can be easily changed through software, making this agile transmitter interesting for use in cognitive radio-based applications.

47 ANNUAL REPORT 2012 WIRELESS COMMUNICATIONS Moreover injection locked class-e power amplifiers were built and characterized in CMOS technologies. The prototypes achieved almost 30 dbm output power. An EER amplifier was designed and built. An envelope detector and a DC-DC converter were included in the architecture. The converter filter is off-chip but the rest of the system is fully integrated. Monolithic power combiners are being studied and designed. These structures will be integrated with the power amplifiers. A TLT and LC baluns and Wilkinson combiners were submitted to fabrication in CMOS technology. An effort was made with the internationalization. Research cooperation with State Key Laboratory from Macau University has also started in this field. The challenge to use new CMOS technologies with 130, 90 and 65nm channel length was achieved. Also an important investment was made in using electromagnetic and systemic simulators. Highly efficient wireless transmitter architectures based on a pulsed operation were also addressed this year in complementing agile transmitters. In that sense the study of the viability of building highly efficient and linear carrier-burst transmitters, namely to study their practical implementation difficulties was addressed. Beyond these works, research was carried on the design of nonlinear behavioral models for telecommunication sub-systems and devices, and their use in digital pre-distortion linearization. The application of these studies has been directed to both conventional Cartesian and polar wireless transmitters, namely for current-mode and switched-mode RF power amplifiers and wireless transmitter systems. Some extra works on a buck switch mode converter at 100MHz was fabricated and tested in a 180nm CMOS, to supply a Class-D PA. A 5V to 1.8V buck converter at 100MHz was also designed and sent for fabrication, using a cascode topology for the power circuit switches, in a 180nm CMOS. The study and design of a fully integrated buck switch mode converter was started. The idea is the increase in switching
