3 a word from the dean tatatiur safety contents Creating a sustainable future through electrical engineering in 2012, kth performed a comprehensive assessment of its research across the university, and the results were clear: the kth School of Electrical Engineering (kth ee) is making a global impact. Just to give you some examples: our researchers are developing both highly efficient drive systems for railway traction, and cooperative vehicle systems that promise improved accessibility, fewer traffic jams and lower fuel consumption. We are also commercialising the world s largest pure-play micro-electromechanical systems (mems) foundry, and building vital infrastructure such as electric field measurement systems for nasa to use in space. For me, these achievements validate our mission of deepening our societal influence while maintaining, and continually improving, our position as a world-class research and educational institution, a synergy exemplified by the 2012 QS World University Rankings, which ranked kth ee among the top 50 schools in the world within our field. We are also immensely proud of the performance of two centres within our school Swegrids and the access Linnaeus Centre of Excellence. Swegrids is a national research centre focused on smart electrical grid and energy storage technology, which was established last year at kth and is headed by Professor Rajeev Thottapillill from our school. access is a long-term interdisciplinary kth collaboration on complex networked communication systems, and a 2012 evaluation commissioned by the Swedish Research Council concluded that access is the largest and leading research centre in its field in Europe, being able to generate world-class research and being highly attractive for international recruitments and exchanges. A first-class school must also provide a first-class study and working environment. Since 2007, we have increased the number of teaching faculty by nearly 65 per cent, from 46 to 72. This growth has strengthened our research capabilities and allowed us to offer our students a more intensive and more supportive educational experience. In fact, a recent survey of kth s Master of Science in Engineering students showed that they are, in general, extremely satisfied with both their teachers and the curriculum. Among all schools at kth, we have the second-highest number of paying students, and we are proud that the number continues to grow. We recently started working on a development plan for the 2013 to 2016 period. The plan will include increased recruiting efforts to attract top students from around the world, as well as pursuing research that lays the foundation for important social infrastructure. This is exemplified by our work on smart grids, cyber security and electrical roads, some of which is presented in this yearbook. Creating this plan is an exciting task, and everybody involved knows that there is only one way to go for kth ee, and that is forwards. Professor Stefan Östlund, Dean, School of Electrical Engineering.

4 infrastructure Security Security infrastructure Protection from unseen threats As the power grid and other systems become smarter and more interconnected with other it infrastructure such as home appliances, cars, the internet, and, not too far into the future, electric roads, augmented reality glasses and driverless cars security is crucial. text david callahan photo istock photo There s no silver bullet or single method for utilities to follow, but by having better information, they will make us all safer. passing the lonely hours during a night shift in the national power utility s control centre, a network transmission operator connects his workstation to the internet and chats with friends over a popular social network. Accustomed to accepting friend requests from strangers, the operator blithely accepts yet another this time with devastating consequences. He has opened up the network to a hacker who unleashes a national blackout. This hypothetical cyber-attack scenario was simulated as part of the eu-financed viking project, an investigation of vulnerabilities in supervisory, control and data acquisition (scada) systems for critical infrastructure, such as power, water and transport. Mathias Ekstedt, an associate professor from kth ee s Industrial Information and Control Systems department, says that a unique dimension to the viking project was its final module, which analysed the cost of cyberattacks to society. Ekstedt was Researchers at the SmartTS Lab at kth ee are working to build real-time analysis and control methods that will give network operators the necessary tools to deal with rapid fluctuations in their network, particularly in a future that includes variable sources of renewable energy. Watch a video on their work at: one of three researchers from different disciplines at kth ee who collaborated on the Framework 7 Collaborative strep Project, in partnership with eth in Switzerland, abb ag and eon in Germany, Astron Informatics in Hungary and mml Analys & Strategi in Sweden. the call for the study stems from the fact that many scada systems were not built to connect with general business it systems or the internet and without a thought given to why anyone would want to penetrate them, Ekstedt says. But, like the fences and walls that have always protected critical infrastructure, it systems represent a new surface for intruders to breach. there s a new way in, Ekstedt says. These systems were not built with security in mind, so new competence is needed. The complication is that it security is very difficult to assess. viking, which underwent its final review in early 2012, provides utilities with models for assessing their risk level and making risk-management calculations. For example, Ekstedt says, a power company using these models could more accurately determine how it should distribute its security resources. Parts of the it structure can vary in their resiliency and at the same time, the consequences of damage vary according to which part of the infrastructure is attacked, he says. to understand the full scope of the problem and to present findings in a context that industry can use, Ekstedt collaborated with the access Linnaeus Centre senior researchers György Dán, Assistant Professor with the department for Communication Networks, and Henrik Sandberg, associate professor with the Automatic Control department. Together, they developed models for a scada system, for the power grid processes, and for the society that is dependent on the electricity supply. The team then proposed actions to decrease risks. Ekstedt says that although the scada model was based on a power grid, such control systems have enough in common with those used in other utilities that several of the models they defined can apply to other kinds of public infrastructure. Finally, the project results were evaluated on a testbed that simulated the critical infrastructure of a power network and a range of attacks. We looked at what happens if some attacker goes here and manipulates some part of the system, Ekstedt says. We could observe the consequences in the power system and, by using a monetary index that we developed, we could calculate the loss in gross national product. the testbed referenced a hypothetical viking country, with a power grid and some fictional cities, that could be parameterised to mimic any country in the eu, to some extent, Ekstedt says. The scenarios were a way of connecting all of the traditional academic models. Taken separately, excellent work was done in each academic domain, but we needed to connect our work for it to meet the needs of industry. The scenarios provided a way of putting the research into context. that context is valuable to public utilities, which Ekstedt says require better risk-analysis tools. Understanding your risks requires better understanding of how vulnerable your system is and what parts need better protection, he says. Then you have to understand the connection and impact of the it asset on the physical world. There s no silver bullet or single method for utilities to follow, but by having better information, they will make us all safer. 6 KTH School of Electrical Engineering KTH School of Electrical Engineering 7

5 access centre Smart mobility Smart mobility access centre Taking the smart road towards efficient transport The Smart Mobility Lab is taking transportation data and using it to build models that will make roads safer, ease traffic and reduce emissions. A prime example of this is research on heavy duty vehicle platoons. Papadimitratos, Associate Professor of Communication Networks, also an access researcher, has been working for years to identify where transport systems are vul- Jonas Mårtensson. Swedes spend 350,000 hours every week in traffic jams. Information from Movelo users can help reduce traffic congestion, by providing up-todate road and traffic conditions. Within the Movelo app, drivers can invite friends to participate, earn points and gold stars and see themselves ranked on leaderboards, one of several gamification features. text Nathan hegedus photo Scania A smart extension of the dashboard A new solution developed by three researchers from kth ee and the access linnaeus centre has the potential to not only save drivers money and increase fuel efficiency, but to revolutionise the automobile insurance business. text Peter Larsson magine four or five 18-meter-long trucks running in a train down the motorway, each truck only three meters apart. Thanks to researchers from kth ee s new Smart Mobility Lab, these convoys could soon be safe, energy-efficient and time saving reality. The Smart Mobility Lab is a model-based lab focused on information and communication technologies for smart and energy efficient transportation. One specific goal is to demonstrate that cooperative vehicle systems such as heavy-duty vehicle platoons can lead to improved accessibility, fewer traffic jams, lower fuel consumption and emissions, plus increased safety levels. The lab has been equipped with More data about our everyday lives and businesses go through the system. a motion capture system consisting of 12 infrared cameras. This system provides indoor localisation that can be used by model vehicles in the same way as a gps would be used by real vehicles. In the near future, there are plans for integrating traffic simulation models and real-time traffic data into the research performed at the lab. With modern communication and sensor technologies, there is an enormous amount of traffic and environment data available, says Jonas Mårtensson, a researcher at the department for Automatic Control and the access Linnaeus Centre. We must first take all the data and turn it into useful information, and then we use it for energy-efficient control of everything from individual vehicles to entire fleets. We coordinate the vehicles on the road and optimise their routes, taking into account the road topography and the current traffic situation, among other things. But the challenge is not just to create more efficient systems but also to keep them safe. Panagiotis nerable and then build in safety and defence mechanisms. Smart systems mean that more and more data about our everyday lives and businesses go through that system, he says. And the more devices you put out there, the more likely they won t be protected enough. The next step for researchers is to start model-based implementations, which will enable them to test more advanced scenarios based on information infrastructures that are not yet feasible to implement in real traffic. Among other benefits, vehicleto-vehicle communication enables smoother adaptive cruise control, which saves fuel, and could also potentially optimize a vehicle s speed with respect to the topography of the road ahead, which has been shown to give fuel savings of up to three per cent on certain types of roads. With aerodynamic inprovements included, the potential fuel and CO2 emissions savings could rise by as much as 15 per cent. drivers are usually discouraged from using smartphones in the car. But Peter Händel takes the opposite point of view: smartphones should instead become an extension of the dashboard. Händel, a Professor of Signal Processing at kth ee, is also the Research and Development Manager for Movelo ab, a start-up focused on traffic and transport solutions. The company has developed a flexible software platform that could have far reaching implications for traffic, fuel efficiency and how consumers pay for auto insurance. Händel is joined on the Movelo team by two kth colleagues Isaac Skog, a researcher, and Martin Ohlsson, who serves as Movelo s Chief Technology Officer. Taking advantage of the latest signal processing techniques, Movelo uses a smartphone s gps/glonass receivers, accelerometers and gyroscope to determine where, how often and how safely someone is driving. Using this data, insurance companies could base insurance policies on when, where and how well someone actually drives, rather than on their age or where they live. Under the programme, safe drivers could significantly cut their bills. I hope the app encourages people to drive more carefully, especially if they know that they can make money from it, Händel says. I like using carrots rather than sticks to encourage safe driving. Tolls and congestion charges are not the only way to reduce traffic during peak hours. The insurance company If Skadeförsakring ab has launched the Movelo solution under the name of If SafeDrive, and it could potentially save users up to 30 per cent off their auto insurance premiums. Movelo has developed alternate versions of the app that emphasise sharing via social media as well as gamification, though these features will not be included in the first version of If SafeDrive. The sharing aspect could be especially helpful in identifying traffic bottlenecks. If we can all help each other and anonymously share information, we ll get smarter traffic solutions and a more sustainable traffic situation in Stockholm and other major cities, Händel says. 8 kth School of Electrical Engineering 2012 kth School of Electrical Engineering

6 access centre Smart home Smart home access centre A smart home rises at the Stockholm Royal Seaport The smart home is becoming a reality at the Stockholm Royal Seaport, and researchers from kth have been integrally involved in a two-year project along with leading construction, utilities, home-appliance and research organisations. text peter larsson and Marie Androv photo Jose García-Valdecasas, Wallenstam och Vera Arkitekter he project is starting with one specific smart or active apartment: a 104sq m space meant for a couple over 55 years old. And kth ee researchers are playing a key role in calculating the efficiency of this home of the future. Sometimes when electricity is cheap, it may not always be environmentally friendly, says Henrik Sandberg, an Associate Professor in Automatic Control, who is also a researcher at the access Linnaeus Centre. It is our job, among other things, to work out the best solutions. Timing is key with appliances. For instance, a washing machine goes through many phases, and each draws different amounts of current. There are a lot of parameters to keep track of. In addition to electricity consumption and a wide array of displays for the inhabitants, the active apartment will also automatically lower the heat or turn down air conditioning when no one is home. But, as Sandberg points out, the resident will always have the last word, with the ability to run their appliances and heating however they like. The smart home should not be a prison, he says. We have had a strong focus on 10 kth School of Electrical Engineering 2012 Henrik Sandberg Associate Professor Researcher at ACCESS usability and ease of use, Sandberg says. If the residents do not use the smart features, the whole concept will fail. As families move into their new energysmart homes, the primary role of kth researchers will be to evaluate the impact of the smart technology inside. Using applied pricing and CO2 measurements, which change from hour to hour, the inhabitants can modify their behaviour in order to save money and energy. Based on initial results, researchers will then be able to estimate the impact of a more general implementation of the methods. Assuming that it is possible to transfer 5 to 15 per cent of daily energy consumption from peak times to off-peak times, a recent kth ee study found potential national savings of up to sek 429 million at current energy prices. Future use of more wind and solar power will likely make prices increasingly volatile in the future, and this could increase the potential savings significantly. The kth ee researchers say it is important to remember that the technology being used at the Royal Seaport is forward looking and not designed only for present conditions. The apartments have been built for the long-term, and in the future, consumers will be able to take an even more active role in determining variable power prices depending on weather conditions, says Lennart Söder, Professor of Electrical Power Systems. All of the numbers in these models are based on energy use in apartments in urban areas with district heating and relatively energy efficient home appliances. Home owners, who usually have significantly higher electric heating costs, would probably see even greater savings. The sek 21.8 million project funded 50 per cent by the Swedish Governmental Agency for Innovation Systems (vinnova) includes kth, Interactive Institute, Electrolux, the construction firm ncc, the housing organisation hsb, the energy companies Fortum and abb, and the property development firms jm and ByggVesta. The concept could eventually expand to 170 apartments in the larger Stockholm Royal Seaport development.

7 access liquibus centre Corunt Big omnias data Corunt Big data omnias access liquibus centre changing the world with wireless data By analysing the big data produced by wireless networks, guest professor Maria Papadopouli is changing the paradigm of how users choose and interact with their wireless providers. text marie androv photo Marie Androv uest professor Maria Papadopouli has always been interested in new computing paradigms especially user-centric grassroots ones. Since the late 1990s, her research has focused on mobile peer-to-peer computing, and now these types of collaborative networks are leading the way towards a significant shift in the way smartphone users may share wireless data. in recent years, the communications market has become ever more diverse with a proliferation of service providers and operators, with both users and networks producing vast amounts of data. Papadopouli has focused her work on analysing wireless networks and developing systems that can empower wireless customers to improve their quality of experience. Papadopouli came to the access Linnaeus Centre for a three-year sabbatical from the University of Crete in Greece. She says the proximity to industry in Stockholm played a key role in her decision to come to Sweden, as well as the plethora of opportunities available for interdisciplinary research and cooperation at access, and at kth in general, in fields including mobile computing, wireless networks, data mining, signal processing, network economics and business. She is working on two projects with particular potential. One revolves around modelling wireless access markets, and integrates game theory, queuing theory and network economics. Papadopouli says her aim is to develop models to analyse large-scale national markets using business-driven With this modelling framework, we can study wireless markets using economic terms. criteria. With her team, she is also building a simulation platform for analysing pricing algorithms, services and types of agreements among operators within a diverse set of customer populations. With this modelling framework, we can study wireless markets using economic terms, while addressing issues of computational complexity and accuracy, she says. And then there is u-map, a crowdsourcing software agent that runs on smartphones the project she talks about with the most enthusiasm. This allows a user to evaluate the perceived quality of experience of a service by providing an opinion score, while the agent also measures network performance in the background. Using the measurements provided by u-map users, the agent can then recommend to visitors the best service provider/operator in a certain region based on that visitor s specific profile. A roaming user can query the u-map for a recommendation about the wireless providers in that region, she says. This may also enable an operator to learn more about its infrastructure possible misconfigurations, intense traffic load, and unexpected trends, for instance as well as about the behaviours and requirements of its customers. The software agent collects network measurements, user reviews and opinion scores into a spatio-temporal geo-database, then performs an analysis, and provides recommendations about various services in a region. This means that consumers and companies can make more educated decisions about which services and network operators to choose in different regions, she says. In theory, that is. Papadopouli is able to run her projects thanks to a research excellence grant she received from the General Secretariat for Research and Technology in Greece. Building on this, she also plans to set up a testbed in Stockholm that will allow her to perform largerscale studies. she hopes that u-map will eventually gain wide acceptance in both the consumer and enterprise segments. U-map constitutes a paradigm shift in the way we can make use of big data generated by wireless users,"she says. I m very excited about experimenting further with this technology here at access. Hopefully it will benefit both my students and industry and then ultimately society.

8 access centre About 3D printing micro and nanoscale ACCESS: all areas The KTH ACCESS Linnaeus Centre has 160 researchers and an annual turnover of about eur 15 million, making it one of Europe s leading university research centres for complex communication networks and systems. Through creative interaction in the areas of networked and cyber-physical systems, researchers are laying the foundations for future solutions in big data, smart mobility, active buildings, cyber-secure power grids, positioning systems, home-based health care and much more. Founded in 2006 on a 10- year Linnaeus grant from the Swedish Research Council (vr), access has exceeded its research goals, doubled its number of faculty members and developed a thriving doctoral programme, with over 100 PhD students collaborating in a rich pool of courses and workshops. The numbers of women both in the faculty and among students have also grown. In 2012 vr conducted an extensive mid-term evaluation of the centre s research, collaborations, programmes and impact on society. The international panel of experts found that access has far surpassed expectations with the collaborative environment it has fostered and the concrete benefits it has generated. The panel found that the centre enhances the international visibility of the scientists involved and the results of their research. This has helped to attract 21 junior tenure-track faculty members to access, making a substantial impact on the broader kth community. Funding for these positions comes from diverse sources, such as government-funded Strategic Research Areas, the ssf Future Leader programme, the vr junior grants or kth ee s strategic research initiatives. Centre faculty members have been recognised with several prestigious awards and grants, including the 2011 ieee Signal Processing Society Technical Achievement Award and a 2012 erc Starting Grant from the European Research Council, as well as more than 20 European Union grants and major collaborative grants from vinnova, the Swedish Governmental Agency for Innovation Systems. access is also actively working together with national and international constituencies on collaborations such as the Strategic Research Area ict The Next Generation, and European Institute of Innovation and Technology ict Labs; industrial cooperation with companies such as Ericsson, Scania, abb, Cisco, and Microsoft; and links with selected universities in the us, China and South Korea. The evaluation resulted in a 10 per cent increase in funding for the coming four years: a total of eur 1.3 million per year, or eur 5.2 million until A virus warning system that detects airborne particles like the virus that causes the winter vomiting disease is only one possible future application for advanced micro- and nanostructures. new dimensions of 3D printing A drawing programme and a 3D printer: in the future, that s all it will take to produce customised micro- and nanoscale silicon structures for sensors and other devices. text benny ritzén illustrations anders westerberg photo Håkan Lindgren D PRINTING IS one of the hottest topics in technology, with the potential to revolutionise manufacturing processes in a vast number of fields. And now, in a proof-of-concept project, researchers at kth ee are taking it down to nanoscale, which could pave the way for cheaper and more accessible manufacturing of customised micro- and nanoscale components in silicon. We have developed a new approach for production of silicon structures for sensors and other devices by combining existing technologies in an innovative way, says Frank Niklaus, head of the research team and Associate Professor in the Department for Micro and Nanosystems. Now that we have tested it manually, it can be used as a model for a new 3D printer that can print the sensors. Production of silicon sensors at micro- and nanoscale with today s technologies requires a full-scale clean-room laboratory, which can cost several million euros. These labs are also not suitable for small-scale manufacturing, as the production technology is usually optimised for large production volumes running into hundreds 14 kth School of Electrical Engineering 2012 kth School of Electrical Engineering

Frank Niklaus. of millions of devices. The new approach developed by Niklaus and his team has the potential to greatly increase the innovation power of both smaller companies and individual researchers and engineers who lack access to expensive semiconductor technology. Also known as Microelectromechanical Systems (mems), these sensors and devices, with accelerometers as one example, are engineered from thin slices of silicon, the same material used to manufacture integrated circuits. mems sensors and devices are used in automobiles, in mobile phones for motion control and can also be used in industry and in medical technology. These components could be made very easily, flexibly and inexpensively compared with today s manufacturing processes, Niklaus says. All you ll need is a 3D printer and someone to draw the structure in a drafting programme on a computer. The new 3D printing technology consists of an additive layer-by-layer process for defining 3D patterns in silicon, using a focused ion beam followed by silicon deposition. The layered 3D silicon structures are defined by repeating these two steps over and over, followed by a final etching step in which the excess silicon material is dissolved away. In the team s vision of the future, the structure would first be designed in a 3D drawing programme then sent to a 3D printer that recreates the structure in silicon, layer by layer from the bottom up. 3D PRINTING tools using materials other than silicon such as polymers, metals, or ceramics already exist, but they are simply not suitable for micro- and nanostructures, according to Niklaus. You really want to use silicon, and that was the starting point for our work, he says. We were primarily thinking about using it for sensors, since that is our area of expertise. But it can of course be used for any type of silicon nanostructure. Niklaus stresses that the new technology should be seen as a complement to large-scale traditional methods, suitable for volumes up to about 10,000 units. For large-scale production, the traditional methodology will always be unbeatable in terms of price per unit, he says. But in many applications, when you just want a few thousands units, it is total overkill to use an expensive semiconductor clean-room facility. THE NEW method may substantially increase the opportunities for more diversified use of mems. It will allow smalland medium-sized enterprises to design mems and integrate them into their products much more often, and in a wider range of configurations than at present. Drastically reduced production costs will create opportunities for small market innovations, much like dropping computer prices did in the it sector. This could allow for manufacturing specially designed sensors for a few patients or creating tailor-made applications for industry at a much lower cost, Niklaus says. Giving engineers access to very easy, specialised manufacturing of a diversity of advanced sensors opens up completely new and creative solutions in medical technology. In 2011, Niklaus received a grant of eur 1.5 million from the European Research Council (erc) for his research on new manufacturing paradigms for micro- and nanosystems. Now he has received an additional eur 150,000 from the erc to look into the commercial side of the technology, work he will carry out in collaboration with kth Innovation. The work done by Niklaus and his team on 3D printing of nanostructures was also recently included in the Watch list of Innovations That Could Change the Way You Manufacture by the Society of Manufacturing Engineers (sme), and will be featured in Manufacturing Engineering magazine and at sme s 2013 Annual Conference in Baltimore in the us. 16 kth School of Electrical Engineering 2012 kth School of Electrical Engineering

10 micro and nanoscale Fighting cancer Fighting cancer micro and nanoscale Targeting tumours with cells in a shell Thanks to a series of innovative collaborations, researchers from kth ee have found a potentially better and more effective way to treat some of the most common childhood cancers. text Nathan hegedus photo linus hallgren Xiamo Zhou, a Chinese PhD student, performs all the daily work on a project to develop a new cancer treatment in which stem cells are encased in polymer shells to focus chemotherapy treatment on a specific tumor. 18 KTH School of Electrical Engineering t all started at a speed dating event that matched kth researchers including Wouter van der Wijngaart, a Professor of Micro and Nanosystems with a counterpart from Karolinska University Hospital working on pancreatic cancer. Both men were working from different angles on encasing stem cells in a new kind of polymer shell to better target treatment of tumours. With research colleague Tommy Haraldsson, van der Wijngaart is working on building a capsule, or porous cage in a polymeric material that encases genetically modified stem cells, which will then be sent directly into the tumour. The modified stem cells will locally produce toxic compounds that will hopefully kill the tumour cells. The polymer cage protects the healthy parts of the body from the stem cells, and vice versa, minimising the risk of the treatment activateing the patient s immune system, as well as preventing the stem cell from turning into a tumour itself. Together with colleagues from Karolinska, the kth ee researchers then received a eur 150,000 grant from the Swedish Childhood Cancer Foundation to investigate whether the same method would work on medulloblastoma and neuroblastoma, which are among the most common solid tumours in children. The treatment may be a potential cure for this disease, which currently has a mortality rate of 35 per cent, while reducing the severe side effects associated with chemotherapy, including hearing loss, thyroid function disorders and secondary cancers. The capsule will be manufactured in a new way on a lab on a chip, which is a chemical laboratory on a microchip, kth School of Electrical Engineering

This makes the cell encapsulation process more controllable. The polymer we use is also a better plastic and we can test the entire packet before it enters your body. Xiamo Zhou, a Chinese PhD student, performs all the daily lab work, starting with building the lab on a chip out of the polymer and then testing the fluid circuits on the chip. She has created the first chips and is now testing them by pushing water and oil through the circuit, before moving on to the polymer materials. The next major step in the project will take place in Shanghai this summer, when the polymer beads will be 20 kth School of Electrical Engineering 2012 injected into mice. Zhou came to kth as an exchange student in January 2012 from Shanghai Jiao Tong University, one of the top universities in China. Zhou actually met van der Wijngaart back in China during a visit for the Joint Centre for Innovation Driven Biomedical Research and Education, a collaboration between kth and Shanghai Jiao Tong University. Zhou then applied for and received a four-year scholarship from the China Scholarship Council, which allowed her to start work on the cell encapsulation project in September. Van der Wijngaart says that without the scholarship, the funding for the project would have run out after about a year. With Haraldsson, van der Wijngaart has started a company Mercene Labs that is selling polymers and plastic products based on the same patented oste Technology platform used in their cancer research. Van der Wijngaart says their material can serve as replacements for off-the-shelf components or considerably reduce product assembly costs in any number of industries, and after one year in business, they already have 15 paying customers in Europe and North America. Kristinn B. Gylfason. Cutting costs down to size Three kth researchers are working feverishly to bring down the skyrocketing costs of developing new medicines. Their solution is a sensor not much bigger than a single cell. Our research will hopefully not only lead to new drugs but also cures for diseases that can t even be treated today, says Kristinn B. Gylfason, Project Manager and researcher at the Department of Micro and Nanosystems at kth ee. Along with colleague and researcher Tommy Haraldsson, also of Micro and Nanosystems, and Hjalmar Brismar, a professor in the Department of Applied Physics, Gylfason has received a sek 3.8 million grant from the Swedish Research Council. The sensor the three researchers are developing encircles a given cell at close proximity. Then, when the cell is exposed to a new drug, the sensor can effectively capture molecules secreted by it. This will lead to definitive trial results earlier in the drug development process and also produce more concrete information on the cell s response to a new drug. kth School of Electrical Engineering

12 european research council Grants Grants european research council To me the success of an engineering research project is about the researcher s ability to develop original solutions to a practical and industrial problem. If along the way, novel analytical methods can be developed, then the project becomes especially rewarding. Mobile web surfing has grown by 150 percent in the past year at mobile operators Telia and Telenor, according to the companies themselves. Faster wireless connections could revolutionise the way we live our lives. A grant from the European Research Council is going to allow one researcher to explore the theoretical possibilities. text marie androv and peter larsson photo håkan lindgren he wireless speed we pay for today is usually pure fiction, says Alexandre Proutiére, a researcher at kth ee and the access Linnaeus Centre. To get the peak rate let s say 10Mbit/s one would have to be the only connection on a mobile Alexandre Proutiére. Pushing the boundaries phone mast using the internet. The same applies to an access point at home, at the airport or at work. The reality of the wireless internet is one of slower and more uncertain speeds. And as if to confirm this point, Swedish mobile operators have been reporting a serious lack of capacity in their networks, as mobile browsing increased by more than 150 per cent in 2012 alone, according to the mobile operators Telia and Telenor. The wireless internet has far more potential than just faster web surfing. Wireless connections have the potential to revolutionise medicine, education and energy usage, to name a few areas. The world is, in many ways, going mobile, and this trend will only speed up, with everything from mobile commerce to augmented reality glasses and driverless cars. So what would it take to bring our actual connection speed up to and beyond what we re promised today? Proutiére is researching a solution called Dynamic Spectrum Access (dsa), which will make it possible for radio devices, such as mobile phones, tablets and future wireless cameras, to become frequency agile, meaning they can rapidly and dynamically access a wide spectrum of bands. This cutting-edge solution would let radio devices move between bands and fill up empty spaces instantaneously. To use the analogy of motorways, the way spectrum is managed today corresponds to forcing people to use a certain lane depending on the car they drive for example, Volvo drivers can only use the left lane, he says. Of course this is particularly inefficient, and our objective is to design systems with higher capacity motorways with much more lanes that allow people to dynamically choose and change lanes. And what is the possible impact of better flowing traffic? Wireless communication that moves 10 times faster, Proutiére says. Plus it will also lay the foundation for the advanced mobile networks we ll see 10 years in the future. In 2012, Proutiére was one of 536 researchers in Europe with 22 coming from Swedish institutions awarded a prestigious erc Starting Grant from the European Research Council to advance his research on wireless communication networks. The erc awarded a total of eur 800 million in Starting Grants last year. Proutiére says the grant will allow him to focus his work on dsa as well as hiring two PhD students and two post-doctoral researchers over a five-year period. This has the potential to become one of the highest profile dsa research projects in Europe, he says. And it also has the potential to increase understanding of problems in areas such as artificial intelligence and robotics. ProutiÉ re s research is ambitious from a theoretical perspective, as it requires an interdisciplinary effort, including theoretical tools from disciplines such as optimisation, artificial intelligence and machine learning. These are all key factors in designing practical mechanisms and protocols that exploit the full potential of dsa. But I also hope that they will provide very valuable insights into many other problems in various disciplines, including multi-agent systems such as industry robots, optimisation, and economics, he says. ProutiÉ re came to academic research via industrial labs at France Telecom r&d and Microsoft Research that focused on practical engineering problems. At first sight, these industrial problems may seem uninteresting from an academic perspective, he says. But the most exciting part of my job was to extract, from these seemingly dull problems, challenging questions that required significant theoretical developments, as well as the invention of new mathematical methodologies, to solve them. To me the success of an engineering research project is about the researcher s ability to develop original solutions to a practical and industrial problem. If along the way, novel analytical methods can be developed, then the project becomes especially rewarding.

13 european research council Grants Roads electrical transportation ERC winners Håkan Hjalmarsson (2011) The LEARN project primarily deals with how system models are built based on measured signals what is known as system identification. An interesting sub-area is how these methods relate to newer technology within machine learning, which has grown from a branch of computer science to involve modern mathematical statistics. Of particular interest are algorithms that automatically decide on how to perform experiments on the system so as to learn about its important properties. Another area is the study of algorithms that are robust to the used model class. This is a joint project between departments at kth ee and Linköping University. Hjalmarsson received the grant together with Professor Lennart Ljung of Linköping University. Advanced Grant: eur 2.5 million About: The European Research Council, erc, aims to support the best researchers in Europe, with a long-term goal to promote scientific excellence and boost the reputation of European research internationally. erc offers a series of grants, including both Advanced Grants and Starting Grants. Advanced Grants support "excellent and innovative research" conducted or led by established and world-class research leaders. erc Starting Grants go to up-and-coming research leaders who are establishing their own research teams and are about to start conducting independent studies. Björn Ottersten (2008) This project Agile mimo systems for communications, biomedicine, and defence targets the emerging frontier research field of multiple-input, multiple-output (mimo) systems. Ultimately, the idea is to develop the fundamental tools that will allow the design of wireless communication systems with an order-of-magnitude higher capacity at a lower cost than that of today; of ultrasound therapy systems maximising delivered power while reducing treatment duration and unwanted illumination; and of distributed aperture multi-beam radars allowing more effective target location, identification and classification. Advanced Grant: eur 1.8 million 24 kth School of Electrical Engineering 2012 In 2012, the erc divided eur 680 million eur 302 among leading researchers from 24 countries in three fields: natural science and technology; the life sciences; and social science and the humanities. An Advanced Grant normally totals eur 2.5 million over five years. Frank Niklaus (2011) Micro- and nano-electromechanical system (MEMS and NEMS) components are vital for many industrial and consumer products, such as airbag systems in cars and motion controls in mobile phones. This project is focusing on new paradigms for flexible and cost-efficient manufacturing and integration of mems and nems within three related research areas: wafer-level heterogeneous integration for mems and nems, integration of wire materials into mems, and free-form 3D printing of silicon micro- and nanostructures. Advanced Grant: eur 1.3 million Göran Stemme (2011) Stemme and his fellow researchers are targeting the development of flexible heterogeneous integration schemes for combining best-of-class materials, components and manufacturing methods into economically viable micro- and nano-electromechanical system (mems and nems) solutions. Specifically, they will develop novel and enabling micro/nano fabrication and integration techniques with a focus on flexibility and cost-efficiency in the following areas: heterogeneous material integration, heterogeneous system integration and lab-on-chip integration. Advanced Grant: eur 2.3 million Recharging transportation on electrical roads Electric car development is primarily focused on fuel efficiency, and until recently, researchers have been seeking answers under the bonnet. But at kth ee, Mats Leksell and his team are looking a little lower, at the street below. text david callahan photo istock Where others see asphalt, the leader of the Electrical Roads project sees a network of smart power supply that could make it possible to drive an electric car all day without having to recharge. We have the technology to power a car while it is moving, with an electrical track in the road that propels the car in a way that s a lot like a slot-car kit, Leksell says. But unlike a toy, an electric car has a battery that enables it to continue driving independently of the road s power supply, when it needs to overtake another vehicle or simply leave the electrified road entirely, he says. Together with a start-up company called Elways ab, Leksell s team has been testing the technology on an electrical demonstration road close to Arlanda, Stockholm s international airport. The involvement in electrical roads evolved from hybrid vehicle research that began nearly ten years ago at kth ee. We lifted our eyes from the vehicles and began to think about the entire transportation infrastructure, Leksell says. Watch a film on how researchers test technology that powers a car while it is already moving: As the car enters the section of pavement where the strip lies, an arm drops from beneath the vehicle, finds the electrical track, and locks in. It s similar to the third rail on a subway line, only it can be confined and made difficult for people to actually touch, he says. Safety is crucial. The team has examined other practical questions, such as how to keep the track from freezing or icing over (the rail can be heated), or how the connection should work (the team is testing materials and techniques for kth School of Electrical Engineering

14 electricaltransportation Roads Vehicles electrical transportation The technology for this already exists. For now it s more of an infrastructure problem to work out. Building models for a world of electric vehicles In a world of nearubiquitous electric vehicles, will the electrical grid be able to handle the increased load? text nathan hegedus photo håkan lindgren connecting and disconnecting a car from the grid). The technology for this already exists, Leksell says. For now it s more of an infrastructure problem to work out. Discussions with the nation s power utilities and transportation ministry indicate that Sweden is probably about ten years away from implementing electrified roads between its major cities, Leksell says. The roads less travelled will be left powerless, however. Leksell says that since the idea is to use energy efficiently, only routes with high traffic volumes will be considered. Frequent traffic will improve the economics of electrification and ensure that power doesn t go to waste. The Electrical Roads concept addresses the major flaw in the electric-car solution for reducing greenhouse gases. We really have no practical storage capacity for electric cars, Leksell says. Fossil fuels are an excellent means of storing energy, but they took millions of years to develop. Batteries don t hold nearly as much energy. They re big and heavy and take a long time to charge. And besides, electricity is a commodity that should be digested immediately, Leksell says. Sweden could be a leader in the electrification of roads because its electrical grid is not dependent on fossil fuels. We don t just shift the combustion from the vehicle to a coal-powered plant, so the carbon footprint will be reduced substantially, he says. Leksell says that if cars are to be part of the solution to global warming, they cannot be viewed in isolation from the rest of the world s energy problems. He envisions an internet of electricity, Mats Leksell. which connects all consumers with a variety of green energy sources: solar from the Sahara, hydropower from the north of Sweden, and wind and wave power from open waters. A recent call for proposals from the eu s initiative on electromobility could allow kth solutions on electrical roads to be compared with others currently in development for mass deployment. But engineering is only one dimension of the overall solution. A PhD student in the industrial economic programme is now investigating different business models aimed at making the concept economically feasible. That s the big question mark for everyone: How do you distribute the costs? Leksell says. This is a case where the technology is ahead, and now society has to figure out how to incorporate it. Pia Grahn. Electric vehicles have the potential to be a true alternative to internal combustion engines, which could dramatically lower greenhouse gas emissions. But they will also impact the electrical grid in hard-to-predict ways. PhD student Pia Grahn is developing mathematical models that examine this tricky question as part of the interdisciplinary Energy Systems Programme, funded by the Swedish Energy Agency. Grahn, who also chairs of the kth ee PhD Council, says there are three primary considerations for determining load profiles and load variations: the charging moment, the charging need and Electric vehicles could potentially help balance supply and demand for electricity. the charging location. Essentially, it is based on where you are able to charge your vehicle, she says. People would probably charge when they arrive at work in the morning and when they get home in the evening. We are looking for the impact on the grid that the increased load would infer at those peak times. With her models, Grahn aims to simulate the possibilities of a future transportation system with large numbers of plug-in electric vehicles, including the potential flexibility of vehicle owners when it comes to the external use of the batteries, in other words, plugging them in. This could have huge ramifications for the electric grid, as increased load variation and load peaks could create a need for costly infrastructure upgrades. This is also important because variable production in the electric power system is increasing, due to higher levels of wind and solar power. Grahn believes that well-designed incentives could transform electric vehicles into the kind of flexible load that could help the power system mitigate these load variations and load peaks. There could also be financial benefits for vehicle owners, who might save money by charging at off-peak times of the day. As the electric vehicle market develops, Grahn says her model could also be extended to include possible scenarios such as electrical roads. 26 kth School of Electrical Engineering 2012 kth School of Electrical Engineering

15 alumni Google Google alumni Getting in at Google without even applying kth ee alum Henrik Lundin beat the odds to land a job at Google, and is now working on technology that could change the way we all communicate. text petra malm photo janne danielsson What I do today will be used by millions of people in just a few weeks or months. sk any student where they want to work after graduation, and Google is sure to be at the top of their list. On graduation, Henrik Lundin was no exception. But I never applied for a job there because I thought my skills didn t fit their profile, says Lundin, who earned his PhD in Signal Processing at kth ee. I thought they were doing more pure computer science, but it turned out that I was wrong. Each year, Google hires a significant number of engineers but the competition is still fierce, with applicants far outnumbering the positions available. Only a small percentage of those interested get an interview, and of these, only a fraction are taken on. Lundin came to Google via a different route. He was employed at Global ip Solutions, a small Norwegian-Swedish company. He and his colleagues developed a unique type of expertise in realtime audio and video technology that Google lacked, so the internet giant bought the company. Today Lundin and his old colleagues work with the rest of the Swedish Google gang in central Stockholm. He works on a technology called Webrtc, which is essentially a standardised interface for browser-to-browser voice and video connections both on computers and mobile devices. With Webrtc, web developers can easily add voice and video communication to their webbased applications by just adding a few lines of code, with no need for plugins, extensions or any separate downloads. Webrtc is being standardised as an application programming interface or api at the World Wide Web Consortium (w3c) and as a set of protocols by the Internet Engineering Task Force (ietf), and is currently supported in the Google Chrome and Opera browsers, with preliminary support in Firefox. Most of the code we have developed, and now worked on, is open source, so it s free for anyone creating a web page, Lundin says. It s cool to work on something where you can directly see the results for end users. What I do today will be used by millions of people in just a few weeks or months. The results are potentially revolutionary, expanding the possibilities of voice and video connectivity from a few channels today to almost any website tomorrow. This could completely change the way companies interact with customers and how we communicate on social networks, and opens up the potential for a vast range of applications in e- health and education. When working on his projects, Lundin has daily contact with colleagues and experts all around the globe. These are very knowledgeable people, and our culture is characterised by cooperation and transparency, he says. If I need to ask a leading expert in a particular field, I often get a response immediately. People at Google are helpful and unpretentious in that way. When asked if he has one tip for anyone who wants to work at Google, he says, Prepare yourself well. In an interview it is not enough to talk about yourself. We ask very technical questions. 28 kth School of Electrical Engineering 2012 kth School of Electrical Engineering

16 profile Impact Impact profile Driven by curiosity Retiring Professor Chandur Sadarangani led major advances in his field, design engineering. But his influence has spread far beyond the lab and classroom through the success of his former students. text david callahan photo håkan lindgren handur Sadarangani knew early on that he wasn t cut out for the family business. Born into an Indian family whose history in the clothing trade spanned generations, Sadarangani saw one sibling after another follow in their father s footsteps, while he became increasingly absorbed in how machines function. If something broke down in the house, I would take it apart because I was interested in why, he says. I usually didn t put it back together, but I was fascinated by how things work. When he retires in November 2013 from his position as Research Leader at Electrical Machines and Power Electronics, Sadarangani s legacy will be evident in the increased efficiency and sustainability of countless power engines used in daily life, from manufacturing systems to hybrid automobiles. His most important ideas were formed during Sadarangani s 15 years in the private sector, first with Allmänna Svenska Elektriska Aktiebolaget (asea) in Västerås and then with abb. But he s quick to also give credit to a number of former PhD candidates, some of whom have leading positions in research and development with abb as well as kth. I had great students, he says. The professor recounts his story in a soft-spoken manner that makes it easy to see why he may not have been suited to work ing in sales with the rest of his relatives. Sadarangani s evolution as an important influence in design engineering began soon after his arrival from the uk, where he lived and worked for a brief period after receiving his Bachelor degree from the University of Manchester Institute of Science and Technology. During a summer holiday in Sweden he met his wife, Kerstin, from Gothenburg; and after some attempts to settle down in the uk, the couple moved to her hometown. Sadarangani was soon enrolled in the PhD programme at Chalmers University of Technology in Gothenburg. My professor took me on the condition that, first of all, I only spoke Swedish, and secondly, that I never addressed him with the formal ni, he remembers with a laugh. After graduating from Chalmers, he was recruited as a design engineer for asea in That s where I learned a lot about electrical machines, Sadarangani says. After that, I was very solid. Five years later, asea was absorbed by abb and Sadarangani entered Corporate Research. Eventually he was awarded a Senior Scientist position in His contributions include developing a U-shaped slot design for engine rotors, which has been patented by abb. The shape reduces the parasitic effects of the converter, which is key to controlling speed. Speed control of the motor is the way to win on efficiency, Sadarangani says. His transition to a professorship at kth was natural. I had a good background in industry and I found that with kth, or a university, you could work with other companies, he says. What is most interesting is that you don t work so closely to the product, so you are in a broader field of research. Upon arrival at kth, his presentation to the predecessor group of the School of Electrical Engineering teemed with a backlog of concepts he had wanted to explore while employed at abb in Västerås. I pursued those one by one, he says. 30 kth School of Electrical Engineering 2012 kth School of Electrical Engineering

17 profile Impact Theory and practice education Sadarangani s former students include his current supervisor, Professor Hans-Peter Nee, and Robert Chin, a manager in corporate research at ABB, who is Sadarangani s boss once a week. As one of the founders of the Swedish Center of Excellence in Electrical Power Engineering at kth, Sadarangani initiated kth ee s Permanent Magnet Drives programme in One of the projects undertaken was the development of highly efficient line-start permanent magnet motors used in pumps by water technology company Xylem. In the area of hybrid vehicles, Sadarangani led the development of the free-piston generator, an energy-conversion device that integrates a combustion engine and electrical generator into a single unit. The hybrid research also led to work on a four-quadrant transducer (4qt), a novel system which consists of two combined radial-flux machines, one double-rotor machine and one conventional machine (stator). The 4qt enables a hybrid vehicle s internal combustion engine to operate at maximum efficiency in any driving conditions. We made a prototype for Volvo Buses, which has shown very promising results, Sadarangani says, pointing out that despite some initial scepticism, his hybrid concepts have been embraced internationally. Suddenly, it s being researched around the world, he says. I recently saw a presentation from Italy and it was exactly the same concept. Industrial relevance is the term Lennart Harnefors, Professor of Power Electronics at ee, uses to describe the research that Sadarangani pursued. A former PhD student of Sadarangani s, Harnefors says that this relevance is the key to the professor s effectiveness in attracting financing. His research has strengthened the electrical machines and drives industry in Sweden through new ideas and methods, as well as well-educated people, Harnefors says. Many jobs have been created as a result. Harnefors says the professor was also quick to embrace and support his student s choice of research topic, even though it fell outside of Sadarangani s personal areas of interest. He was always very pleasant. Chandur s career shows that you don t need a big ego to be a great professor. By Sadarangani s own account, the key to his success has always been his insatiable curiosity. And his journey isn t over just because We made a prototype for Volvo Buses, which has shown very promising results he is retiring. The professor will continue working as a consultant, and he ll go on exploring his passion in his free time, as well. Electrical machines are used in so many applications; every time something new comes along, I must find out what s new about it, he says. Every time I see something new that I don t understand, I cannot resist the impulse to try to understand it. Creating something out of nothing What do you get when you tell a class of second-year electrical engineering students that they have to work in small teams to build a loudspeaker from scratch? A lot of work, a lot of good ideas, and a loudspeaker made from paper, particle board and a beer can. text Nathan hegedus photo martin ekelund For the team comprising of Evelina Jakobsson, Gabriel Haddad, Emil Mårtensson and David Wikman, the journey started last October, not in the lab but with a single lecture on modelling and then extensive independent grounding in theoretical calculations on, for example, the nature of acoustics or the proper thickness of copper wire. The students presented their plans to the instructors, eventually moving on to simulations before presenting their final designs. There was regular supervision, but the project is very much kept to their own time, says Martin Norgren, Professor in Electromagnetic Theory, who together with a team of professors has developed the course. The benefit is that they can combine knowledge from different courses and see you cannot be an expert in just one area if you want to be a successful engineer, he says. The problem is not purely electrical or mechanical, and there is other physics involved as well. And Jakobsson, Haddad, Mårtensson and Wikman put in a lot of their own time. They spent hours each day, collaborating as a group, breaking off into teams of two, or going off on solo tasks, all in their effort to translate 32 kth School of Electrical Engineering 2012 kth School of Electrical Engineering

It will be something with a lot of midrange, probably guitar-based. electrical theory to mechanics, a far more complex task than they had expected. The idea behind the class is very good, integrating practical work with theory, Jakobsson says. And the actual building wasn t too hard. Instead, the challenge was deciding on materials and figuring out how it all works. The students can t use parts from commercially manufactured speakers, except for the permanent magnet, and they get only sek 1,200 as a group. And after that, it s all on them to figure it out. So when they finally got a chance to build, the group first looked for easy-to-work-with materials and after some trial and error, decided upon particle board for the speaker s box. For the voice coil, which interacts with the magnet to make the speaker work, they tried photo-grade paper, but that proved too thick and too weak. That s when someone spotted the beer can and started cutting. Aluminium seemed to be a good answer. Looking at their loudspeaker, you wouldn t guess that it s the product of months of devoted study and construction, but that s exactly the point. They ve taken the safe route and kept it simple, and spent only sek 600 so far, leaving plenty of room for last minute improvisation as they build the box around the speaker and near their first tests. As they stand in the lab, their half-built speaker before them, it is clear the students have taken in the lessons on melding theory and project-based work, as well as mixing the electronic and mechanical aspects of speaker building. Jakobsson says they still almost always meet all together, even if they need to work on tasks alone. They work well together, falling into an impromptu discussion about the best kind of glue for attaching a piece of insulation material for the speaker s suspension, another example of how the group is using simple and inexpensive options. It needs to be elastic, Jakobsson says, holding up the strip. But not move too much. For all their hours in the lab, there were still a couple of big questions left unanswered as the group prepared for the final exhibition, in which all eleven teams demonstrated their speakers, with awards given for both the students and professors favourites. The first question was whether their speaker would work they hadn t tested it yet. The second was both simpler and yet vastly more difficult. They had to agree on what kind of music to play for the exhibition. It can t be the heaviest hiphop because we lack the bass, Mårtensson said with a laugh before the exhibition. It will be something with a lot of midrange, probably guitar-based. In the end, the exhibition went well, and the group shared the professors award. They also played not one, but a series of songs. Which was their favourite? Jakobsson says it was Skeletons by Stevie Wonder. 34 kth School of Electrical Engineering 2012 kth School of Electrical Engineering
