At the moment of writing this editorial, we are in the middle of the Olympics Games in Sochi, were the Dutch athletes are making their country proud, measured both in medals and in showing team spirit. When focusing on what is happening in our depart-

ment, both students and employees also have important highlights that we would like to share with everyone in the department.

One of the major highlights in the past period was of course the NWO Gravitation grant that will have a big impact on our Department. Prof. Smit informs us about the new Research Centre Integrated Nanophotonics and Prof. Koonen provides some details about the Networks program. Also in this issue of the Connecthor, we check in with interesting projects moving forward, including the PhD project on prediction of thermally induced imaging errors in photo-lithography by Can Bikora.

If you’re looking for inspiration for an internship abroad, please have a look at the articles by Celine Vincent or Gerald Drenthen on their internship in Japan. And Thor, Waldur and Odin have organized some nice excursions to Erasmus MC, Damen Shipyard, and the Automotive Campus

Alfons Bruekers, our new Managing Director for the Electrical Engineering Department, intro-duces himself and Suzanne Udo, our previous Managing director says goodbye to us. Finally, the Connecthor editorial board has to say goodbye to one of its members, Jerom de Haan. Jerom, thank you for your contributions to the Connecthor over the years. It has been great to have you in the editorial board!

As always, we will be glad to receive your suggestions and ideas for upcoming editions and you can contact us via connecthor@tue.nl. We hope you will enjoy reading this new edition of the Connecthor!

Board IssuesBy: Ton Backx

Board Issues is a recurring item in the Connecthor. Each issue, a member of the faculty board is asked to write about current issues in the department that would be interesting to the Connecthor readers. In this edition, the dean of Electrical Engineering presents his speech for the New Year’s drink. Topics like the Bachelor College, Graduate School and Project fundings are touched upon. Achievements in 2013 were acknowl-edged, hellos and goodbyes were said and an outlook on what 2014 has in store for the department of Electrical Engineering was presented.

New Year speech January 7th, 2014

Ladies and Gentlemen,

I first of all wish you a Happy and Healthy 2014! I hope that you will be able to make your dreams and wishes come true this year!

2013 Was a challenging year for our faculty. I want to mention some highlights:

• The continued strong growth in the number of first-year students entering our EE Bachelor and Automotive program

• Further improvement our efficiency in the number of students finishing their Propedeuse within one year as needed for further improvement of our effi-ciency and meeting our performance targets set for 2016

• The successful completion of the first year of our Bachelor College

• In connection with the Impuls 1 program we have been able to further strengthen our ties with industry (Philips, ASML, Maxima Medisch Centrum, NXP, ProDrive, …) as needed

• Just before Christmas we received the formal confirmation that our NWO Zwaartekracht proposal has been selected for funding.

• We have been able to keep our depart-ment finances healthy despite the signif-icant reduction in our direct funding

(“First money stream”) and the poor economic situation in the Netherlands especially

For the third year in a row we have been able to establish a significant growth in the number of first-year students choosing our EE or Automotive Bachelor. With 152 students we are now well on the way towards 200 freshmen starting our Bachelor programs.

Further improved attention for our first-year students definitely is paying off with a significantly lower drop-out of students during the first year. The personal interviews and the intensive coaching of the students clearly motivate students. Only people that have real difficulties passing the exams

have stopped their study with us in the first half year. Although we see differences this year between the students taking the EE and the Automotive program, the overall number of first-year students that will get a preliminary negative advise is again expected to be low. As you all know we need this to meet our performance targets set for 2016.

The Calculus problems we faced last year have been resolved this year. Also Computation went more smoothly than last year although the exams still were slightly disappointing to the team responsible for the course. Kees Goossens made a very successful contribu-tion to the Bachelor College basic course Design. Kees has been able to get the majority of the second year students taking his classes.

A lot happened in 2013 again. People I want to mention specifically:

• The success of the EM group in the HTSM call beginning 2013. Anton Tijhuis and Bart Smolders succeeded in getting funding for three projects.

• We were all shocked by the stroke that caught Reza Mahmoudi. Reza is working very hard to recover and to pick up his activities within the MSM group. We wish Reza lots of success and the strength to catch up again.

• The Photonics team headed by Meint Smit that worked hard to get NWO Zwaartekracht funding (M€20) for the next 10 years. This funding secures the intended continuation of world-class research on photonics after NRC Photonics top research school funding stopped on January 1st.

• Marion Matters deserves to be put in the spotlight as the responsible teacher of the Bachelor College first-semester course Circuits. For the second year in row this course was the best.

• The formal next step in expanding our Center for Cure and Care Technologies Eindhoven by the kick-off organized by Peter de With and Massimo Mischi. A solid basis has been set for further expansion of our cure and care technolo-gies research.

• I want to thank Suzanne Udo for her contributions as managing director of the faculty to help shape our faculty into the healthy and competitive orga-nization we are.

In 2013 we again faced significant financial challenges due to a further cut in our first money stream budget. The continued reces-sion made it hard to attract funding for new projects. We nevertheless have been able to cope with this major challenge very well in the course of the year. We closed the books on 2013 in accordance with our expectations. Overall, we may conclude that our faculty did well in 2013. I want to thank all of you for your contributions to realize this.

Now looking ahead we may expect 2014 to be a challenging year again.

Further attention will be needed to strengthen Automotive skills within our department. The rapidly growing number of students requires more capacity. To meet the needs, we will carefully look at the skills we are lacking and hire the people required. We definitely will also call upon all of you to contribute to specific courses and projects.

Further cost reductions have been announced by our government to improve the financial situation of our country. The additional cost savings will have a negative impact on our budget in near future. In the past we have demonstrated to be capable to generate the funds needed to keep our organization financially healthy. We have shown that we can compensate for the loss of direct funding by attracting more money from 2nd and 3rd streams.

Currently all of our Capacity Groups have a sound financial basis despite the fact that we lost more than 25% of our direct funding over the past 7 years. As we have a well-performing organization and as we are a strong team, we – the Board of the Faculty – have decided to cope with the financial challenges we are facing by further strength-ening our national and international market positions. This implies that part of the project funds we acquire will be needed for paying our permanent staff member salaries and our operational costs. It also implies that permanent scientific staff members will have

We strongly believe in our capabilities to win the projects and get the funding required as

we have demonstrated the past years.

06 | connecthor

I Department

to spend more of their time in R&D activities themselves. We will adjust the organization as needed to get the necessary additional external funding. Although it will require significant effort and contributions from all of us again this year, we strongly believe in our capabilities to win the projects and get the funding required as we have demonstrated the past years. To assure that we don’t have to reorganize in the near future I call upon all of you to help keeping our financial position sound by contributing to and supporting the acquisition of external funding (2nd and 3rd money stream funding).

Our Centre for Wireless Technologies Eindhoven, Centre for Care and Cure Technologies Eindhoven and Centre for Power and Energy Eindhoven will be further strengthened to assure a solid basis for further improvement of our visibility and of our performance in acquiring the neces-sary funds. Special attention will be oriented towards our Centre for Power and Energy Eindhoven. It will be necessary to appoint a Scientific Director and a Project Officer to further develop it and to make it perform. It will play an important role in connecting to the national and European Smart-Grid developments and to strengthen our rela-tions with industry in related fields.

New initiatives will be taken related to the university wide “Valorisation Program”. As you all know, this program focuses on smooth exchange of knowledge with industry and societal parties for application

and product development. The further interaction with industry and society will help us to attract the funding required for our research programs. To improve our effi-ciency we will need to adapt our organiza-tion in accordance with market changes. Diversification in the way we work together with industry will be necessary. Industries are showing increasing difficulties with commit-ting to finance four-year PhD projects. They look for short-term results and are prepared to pay for these results, but are facing prob-lems in committing finances for long-term research activities. We will have to get more of our experienced staff members part-time involved in short term valorization projects with industry. The money earned with these activities will be used for (co-)financing longer term PhD and PostDoc positions. At capacity-group level we will try to predomi-nantly request for contributions of people in accordance with their strengths.

This year we will continue the build up of our Graduate School. We need to continue and establish university-wide coherence in the programs of our Bachelor College and Graduate School.

We need to motivate our students to work towards passing their exams at their first attempt as much as possible to meet the efficiency targets set for 2016. The efficiency target of each exam needs to be set at 70% or higher. Looking at our current performance this still is a challenge as we don’t give up on quality and level.

This year we want to further increase the number of first-year students starting their Bachelor study in Electrical Engineering or Automotive Engineering. We are dreaming of 200 students starting in the Bachelor program in September 2014.

This year will also be the year in which we move to our new premises. The new building is definitely going to provide class and comfort, but it will also bring up some chal-lenges. The area available within the new building will be far less compared to the space we do have now. This implies that we have to

prepare for organizing the way we work in a different way. Together we need to figure out the way in which we can make best use of the new office and lab spaces we will get. I want to ask you to be creative and open your minds for the opportunities this will bring.

I want to give a very warm welcome to Alfons Bruekers as our newly appointed managing director since January 1st. We look forward to a very constructive collab-oration that will help us meet our targets continuing as a strong and winning team.

The turbulent world we live in will confront us again with all kinds of challenges in 2014. Some are foreseen as indicated above and some will be unexpected. The winning team spirit we have created together within our faculty convinces me that we will be able to find solid solutions for the problems we will face. The challenges will even make us stronger than we have been so far. We will all have to contribute to make sure we remain at least as healthy as we are now and to even further strengthen our position in this competitive world!

“Plentiful space for personal development”

Adv_Connecthor_jan14.indd 1 16-1-2014 13:56:33

From the PresidentBy: Esmee Huismans

In the year 1963, our association settled itself in the building E-Hoog. After being here a bit longer than 50 years, we have

to say goodbye to our beloved building. We are going to move to another location at the TU/e in less than a year, namely the building Flux. We will get a new boardroom together with our master associations and IEEE SBe and a new Walhalla. Instead of being located on the second floor with our boardroom and on -1 with our bar we are going to move to the sixth floor. Moving brings a lot of changes, for one the amount of storage space.

Because the space for storage is divided differently we decided as a board to sort out our current storage room. Through sorting we came to know exactly what we have. Therefore everyone who has a connection with our association gets an opportunity to regain a piece of memory. While cleaning and sorting we found several items which were collected over the years through activities that were organized, committees who made yearbooks or journey reports, pictures that were made and some random stuff that has been collected.

The time it took us to clean and sort our main storage room was approximately 3 days. During the first day the main thing we did was throwing away rubbish. During the second day we counted all the old yearbooks, Orathors and Connecthors we found. The last day our focus was on photographing the various items we found. That is because we would like to get rid of all the stuff we found by making a bidding place for everyone connected to Thor.

While figuring out what stuff we have, you come across some unexpected things. We found 122 copies of the yearbook of 2002, but also one copy of the first yearbook made by our association. We also found lots of clothes. Some for dressing up, others were old shirts from introduction weeks and sweaters from the 10th lustrum. Furthermore, we found books from the 3rd and 6th Walhalla lustrum. However we also came across stuff we did not count on finding.

A large rolled up canvas was standing at the back of the room. On the third day we finally could get it out of the room and discovered what it was. It turned out to be a disco ball of

5 by 5 meters. After asking around we figured out what it was used for. This huge 2D disco ball was used as a decoration on a dies party. We already found some unexpected stuff, like a surfboard and a pool table. But we did not expect to find this.

The most remarkable thing we found was not one item specifically. We all enjoyed regaining old items that belong to our association. Like our logo that is painted on a canvas, or frames from the ’80s, but also hoods and quite old yearbooks. The three days we spent in the storage room was hard work, full of counting, but it was also nice to find several items that were collected years ago. As a board we really hope we can give the people who are connected to our association a piece of memory back by finding these items and giving them the opportunity to own one of these items.

Veel Gedonder!

Introducing...

Hi everyone!

My name is Rachana and I am from India. I was born and brought up in

one of India’s biggest metropolitan cities - Bangalore. I have a Bachelor’s degree in Computer science and a Master’s degree in Embedded Systems (BITS Pilani University, India). My research interests include computer architecture and operating systems. I worked on cache memory subsystem design and optimization during my post-graduation. I joined the Electronic Systems group of the department of Electrical Engineering as a PhD student in December 2013. My PhD work is about finding energy efficient solutions for heterogeneous multicore communicating systems by means of virtualizing the multi-core resources.

When I am away from work, I love to travel, explore, and experience new places and cultures. This being my first time in The Netherlands, one of the first things on my list is to buy a bicycle and start exploring. Adding to that, I also enjoy photography, cooking, and travel blogging.

I have heard a lot of good things about the university and The Netherlands, and I look forward to an enjoyable and pleasant stay here.

I am Song Ma, a recently joined post-master student in the group of Mixed-signal Microelectronics. I was born in Fushun, in

the northeast part of China in 1986. I got my bachelor degree of electrical engineering at Hunan University in 2009. I came to Enschede to have my master program at the University of Twente in 2010. After two and half years, I got my M.Sc. in Electrical Engineering special-izing in IC design. Now I am doing my PDEng in the department of Electrical Engineering. The project is to design a millimeter-wave phase-locked loop.

I play basketball with a couple of friends. Most of time, we play basketball once a week. Now I am planning to learn tennis. I am also a big soccer fan and I like to travel around. I am a man with curiosity. I am interested in the things I didn’t know before, especially history and culture.

I am looking forward to the new adventure at TU/e!

I Department

My name is Hernan Guidi, I was born in Sucre - Bolivia and partly raised in South Africa and Venezuela.  I

started my BEng - Chemical Engineering degree at the University of Birmingham in the UK and completed it at the University of Pretoria - South Africa with honors. I went on to complete an MEng degree in Control Engineering at the University of Pretoria in 2009 with my research topic being system identification and model validation applied to a pilot scale distillation column. 

Mid 2009 I began working as an advanced process control engineer at SASOL - a South African Synthetic fuels and chemi-cals producing company. My duties mostly involved commissioning and maintaining

model based controllers and optimizers on both the gas and liquid synthetic fuel processing units and refineries.

After 5 years in industry I’m very happy to be joining the Electrical Engineering depart-ment at TU/e. As part of the Control Systems group I will be involved in an exciting partner-ship with ISPT and some industrial partners in aligning rigorous models and their online application towards continuous process control improvement and optimization. 

I can add that I am a squash fanatic, so if anyone is looking for a game or a training partner, let me know.

All the best

Hi everyone!

My name is Joost van Pinxten, I just turned 27 and finished my Master

in Electrical Engineering at the TU/e. After finishing my Master project on using model transformation software for design space exploration, I spent my summer break in York (UK) for an extra internship. Before starting my PhD from the 1st of January, I worked at Embedded Systems Innovations (TNO) on the integration of tools in a data path simulator environment for Océ Canon.

I am looking forward to start my work in the Cyber-Physical Systems project in the Electronic Systems group. The research will be carried out under the supervision of Twan Basten and Marc Geilen, in cooperation with Océ Canon Technologies. We will start by looking into ways to improve the efficiency of handling paper in the paper path of high-volume copiers, while meeting real-time requirements.

Currently, I am interested in creating new opportunities by combining existing technol-ogies from different disciplines and applying these in new areas. I have taken an interest in software visualization, modeling for and using discrete event simulators, and (graph-ical and textual) domain-specific modeling.

My hobbies include listening to a variety of music, watching TV series, playing squash or table-top games with friends, or creating solvers for the Connecthor puzzles automati-cally (check out ConstraintPuzzler ;-)). See you around on campus!

Faculteit draagt indirect ook steentje bij aan Serious RequestOnze faculteit is indirect ook actief geweest als donateur van 3FM Serious Request. Hanneke (dochter van opleidingsdirecteur prof. Bart Smolders) heeft een aantal posters gemaakt en opgehangen in ons gebouw, o.a. naast de lift. De donaties van onze faculteit hebben bijgedragen aan het totaalbedrag van 40.685,91 Euro dat door de middelbare school Metameer uit Stevensbeek bij elkaar verzameld is. Maandag 23 december 2013 is een aantal leerlingen van deze school naar Leeuwarden gegaan om de cheque te over-handigen aan de 3 FM dj’s in het Glazen huis. Nogmaals dank voor jullie giften!

VlaaiOp donderdag 9 Januari 2014 was het dan eindelijk zover, Guus Vermijs, redactielid van Van der Waals, kreeg een taart uitgereikt vanwege zijn recensie van de Connecthor. De vlaaitraktatie vond plaats in Cascade op het Tu/e terrein. Zijn positieve woorden over ons blad, mooi en professioneel, vragen om een beloning. Met zijn kritiek dat wij van elektro een stelletje nerds zijn en men meer creativi-teit mag verwachten, daar moeten we natuurlijk volledig mee instemmen. Vooral aangezien ze bijVan der Waals een prachtige indruk hebben achtergelaten tijdens ons bezoek, met een zeer georganiseerd en gestructureerd kantoor, waar nerds en pukkeltjes ver te zoeken zijn, net als het ontbreken van een warme klamme lucht gegeneerd door de aanwezigen. Al met al was het een zeer geslaagde vlaaitraktatie.

First graduate HSDHossein Nassabi is the first graduate of our new Health-care System Design (HSD) program. He received his PDeng degree from Dr. –Ing. Marion Matters on 12-12-2013.

Best Paper AwardOn November 26th 2013 Alonso Millan-Mejia from the Photonic Integration Group (PhI) won the best poster award on the 18th Annual Symposium of the IEEE Photonics Society Benelux Chapter.

RoboticadagOp dinsdag 21 januari en 28 januari ontving de Faculteit Electrical Engineering samen met de Faculteit Werktuigbouwkunde brug-klassers van het Van Maerlant College en het Sondervick College en 3e klas scholieren van het Maaslandcollege. De brugklassers kwamen op bezoek om meer te weten te komen over Robitica. We hebben ze meegenomen voor een tour langs de voetbal robots, de zorgrobot Amigo, de URE raceauto, Ecomotive team, de hartslagmeter en de Tesla Coil. ’s Middags hebben we ze aan het werk gezet. Tijdens de workshops (mindstorms, schakelborden en verschillende EE workshops) hebben we de groepjes, waarin de scholieren waren ingedeeld, gerouleerd zodat ze zoveel mogelijk zelf konden ervaren hoe leuk techniek is. De derdeklassers van het Maaslandcollege hadden een geheel eigen programma, omdat de school had aangegeven dat het onderwerp over duurzaamheid diende te gaan. Zij begonnen hun dag samen met de brugklassers, maar na de presentatie van Gijs Dubbelman over robo-tica kregen zijn een tour langs het AES lab, de motorcellen, Ecomotive en het Solar Team. Na de lunch kregen ook zij een workshop. Ze moesten de Solar Team case oplossen. Als afsluiting werden alle scholieren en hun begeleiders getrakteerd op een zakje chips en een glaasje fris in het Walhalla.

I News

Excursion Automotive CampusBy: Linda Janssen

On an early Monday morning, we left for the automotive campus located in Helmond. We visited 3 different

companies: TNO, TASS, and Benteler. We started out with presentations from TNO and TASS. TNO is an independent research organi-zation that operates in almost every technical branch that exists. TASS is actually a spin-off company of TNO that is specialized in soft-ware engineering.

After the presentations we had a tour to the two companies. On the automotive campus they do a lot of crash testing and analyzing. At that time, they had an assignment to crash some very expensive vehicles that was quite a shame, in our eyes. At TASS, we saw an auto simulator that you could drive like it was an arcade game. All in all we saw almost the entire campus and walked, what seemed to the 2 ladies wearing heels, for miles.

When the tour was over, we went to Benteler. Benteler is an engineering company that does a lot of assignments in the automotive branch. We got a presentation of the company before we went on a tour to the workplace. A very impressive project they finished was the completion of a hybrid garbage truck. The truck reloads its battery while it drives to and from the landfill so it can drive in the city center emission free and almost noiseless.

After finishing this final tour we were done at the automotive campus and it was time to return home. After a short walk to the train station, which the 2 formerly mentioned heeled ladies did barefoot, and a few minutes in the train, we arrived once again in Eindhoven to continue our day.

Wearing a different cap!By: Rianne van Eerd en Diana Heijnerman

On January 1 2014, we began our duties in the newly elected staff section of the University Council (UC).

We never imagined we would get so many votes! Together we collected 25% of the total number of votes – probably for the most part from our own Department. But did you all realize what you were voting for? When we visited the EE offices in December throwing ‘pepernoten’ in the Dutch Sinterklaas tradi-tion, we got the impression that not everyone is familiar with the University Council and what its members do.

As a member of the University Council you are committed to all kinds of subjects dealing with the University as a whole, such as educational innovation, the infrastructure and re-structuring of the TU/e campus, the TU/e budget and all sorts of regulations. In short: the University Council can have a say in anything that the University Board decides on. This means that our field of interest stretches further than the Department of Electrical Engineering. Department-oriented subjects are tackled by the Departmental Council and the Board of the Department. For the UC it is important to know how its

central policy affects things on departmental level. Therefore it is important to keep in close contact with the Departmental Council.

Depending on the subject at hand, the UC has a right to be informed, to initiate, agree on or advise. The first big item on the agenda is the Model OER (education and exam regulations). In February this was already discussed with the Departmental Councils and it will be on the agenda of the University Council in April to be approved. By the way, all UC meetings are public, so everyone is very welcome to attend. The schedule of the meetings is available on the

following link: http://w3.tue.nl/en/services/daz/university_council/meetings/dates_of_meetings/

For approximately one day a week we will be occupied with UC matters. This is completely different to our daily work at the EE Department. Wearing our other cap, we will approach you and, of course, you can always approach us with questions, points of view and subjects that concern the University as a whole. The UC agenda is not dictated by the Board of the TU/e; we ourselves can initiate points for discussion. We look forward to a fruitful and interactive cooperation!

More than 7 years EEBy: Suzanne Udo

For nearly 8 years I worked in the Department of Electrical Engineering. Day by day the department changed:

slowly, but continuously. For instance, in 2006 the name of the department was Dutch: Elektrotechniek. In 2009 we renamed the study program as well as the Department to “Electrical Engineering”. Two reasons for that: the Dutch word “elektrotechniek” has a connotation of craftsmanship instead of the really highly technological and scientific work we wanted to point out. The other reason was that more and more students and employees came from all over the world. We gradually changed to English. First the master curric-ulum, 2 years ago the bachelor curriculum, and just recently the Horizon-gatherings (staff with the board of the faculty) turned to English, in order to include all the ‘Non-Dutch’ people in the faculty. In other words: we are gradually coming to a position of (more) international inclusiveness (although the guys from abroad will suffer from misunder-standing and typical Dutch rudeness from time to time –I’m sorry for that).

By chance my son became interested in technical studies. As it stands, he chose for Electrical Engineering at the TU/e. His expe-riences and observations were sometimes a little sobering for me as member of the board of the department. The ideology of the

Bachelor College seems to work out well in some respects, but not in all. For instance the choices that Bachelor College aims to provide, are not that easy to get in daily life, partly due to time schedules, but also because nobody is expecting the real individual choices that students could take.

Another observation of his that surprised me: the difficulty of courses is varying a lot. I think we will have to find out how to calibrate that in the Bachelor College.

Most probably the conclusion will be that Electrical Engineering asks very much of its students per ECTS compared to other depart-ments. We are proud of our high standards, but what are the side effects? The government demands higher success rates and in addition to that, more students taking ‘honor classes’. With our standards, that is nearly impossible.

The definition of what the new building ought to be was an exciting (and sometimes enervating) process for the department, and especially so for me. I trust the outcome, Flux, will be an improvement, despite of the fact that there will be significantly less space. The last phase -commissioning - will cost a

lot of creativity and hard work, but I am sure the new housing will help to attract more students and will facilitate the research in a more efficient way than Potentiaal, Impuls, and Corona do nowadays.

I feel I have had the honor to work amongst hardworking ambitious and successful scientists. Especially the cooperation with Ton Backx has been inspiring, although (or because?) our personal styles differ a lot.

I was engaged in the department in a wonderful time; in these years the depart-ment grew roughly from 60 to more than 150 first-year students, partly as an effect of the start of Automotive, and from approxi-mately 90 to 170 PhD students. The turn-over of contract research increased from 8 million to 16 million. Huge numbers in times of economic recession! The members of the support staff on the first floor deserve a lot of credit for succeeding at accommodating this growth.

I thank you all for the good times we had and wish you even more success for the future.

I Department

New Managing Director By: Alfons Bruekers

On 1st January 2014, Alfons Bruekers was appointed as Managing Director of the Department of Electrical

Engineering. He would like to introduce himself to you.

Let me start with my Curriculum Vitae. I am 52 years of age and have been working at the TU/e for seven years. I studied Electrical Engineering at the TU/e – and now I will be taking over the role of Managing Director from Suzanne Udo in the very same depart-ment. After completing my studies, I worked in industry for 21 years at the R&D Department of Océ. I worked originally as a measure-ment and control engineer and later as an international project leader concerned with the development of copiers and printers. In 2000, as head of R&D, I was responsible for all developments in the field of digital imaging technology and modular control platforms for both hardware and software.

In 2006, I was a guest at the Alumni celebra-tion marking the 50th Anniversary of the TU/e and by chance I got talking to a recruiter from the TU/e. To cut a long story short, on 1 January 2007 I began as Managing Director of the Department of Mechanical Engineering; for the last two years this was also in combi-nation with the Applied Physics Department.

TwitterWhat else can I tell you? I live in Nederweert-Ospel and grew up in a ‘technical nest’ with most people around me studying at the TU/e. I am married to Tiny and we have three chil-dren. The eldest is studying at the University of Maastricht. In my limited spare time I like to write about culture, history, art and arche-ology and am a member of various cultural committees in Limburg. I have been a Twitter user from day one (@bruekers) but I limit this to matters that concern the department(s) and the TU/e.

Double functionI will be combining the position of Managing Director EE with the same position at Applied Physics. Some people ask me if this means a fusion of the two departments is imminent. That is absolutely not the case. Both depart-ments have their own very different charac-ters: Electrical Engineering is geared more to technical application and Applied Phyiscs is geared more to fundamental research, each has its own programme, external cooperation contacts, identity and pride. This is something to cherish and not to fuse together. It does mean, however, that working together in Flux under one Managing Director will inevitably create new chances for cooperation in areas where it can really make a difference.

Beta Managing DirectorMy ‘beta’ education profile is in my opinion a small advantage in my position as managing director. With such a profile, one is better able to understand the passion, drive and goals of electrical engineers and physicists. From a managerial point of view, I can under-stand the language of research and educa-tion and provide a better service as manager. Moreover, I try to apply my experience in industry, in carefully measured doses, within my departments and it’s great to do this. I am supported in this by my deputy director Ms. Jolie Boot.

Listening and being surprisedMy first days at Electrical Engineering have been spent with meeting people and talking with my new colleagues and team mates. It was really nice that after my appointment was announced, the first congratulations came from the Student Society, maybe because I was a former member of Thor but anyway it was a great experience. Student organiza-tions contribute a lot to a department and this also applies to spin-offs and start-ups.

It is an open door but for our department, the main way forward in 2014 will be ‘The Road to Flux’. Moving and organizing our workspace will take a lot of effort and puzzling but we will get a beautiful and practical building in return. And as I said: sharing the front door with the Applied Physics Department will create opportunities that will benefit the primary process and management.

Let me finish here for now - I am really looking forward to working with you all!

Prediction of thermally induced imaging errors in photolithography

Driven by the unceasing demand for increasingly smaller electronic devices, advances in photolithog-

raphy have provided the means for semicon-ductor manufacturers to continually shrink feature sizes over the years. As a consequence, this has imposed more stringent require-ments at the nanometer scale for tolerable levels of imaging errors. Thus, compensa-tion mechanisms in wafer scanners for such errors should operate effectively in terms of consistently keeping the errors within their specified bounds. My PhD thesis is concerned with the mitigation of thermally induced errors by means of providing accurate predic-tions of them to the corresponding control systems. These errors are mainly introduced by heating-induced deformation of the reticle and the elements of the projection optics, as a result of the energy emitted from the light source during exposures. In the scope of the thesis, the thermal deformation of the reticle is treated in the context of extreme ultra-violet (EUV) lithography, whereas the same phenomenon on the projection optics is considered in deep ultraviolet (DUV) lithog-raphy where the projection lens is the compo-nent in use. These two areas of investigation are referred to as the reticle heating (RH) and the lens heating (LH) cases.

Online predictive compensation mechanismWhen looked at from an abstract level, the mechanism that alleviates a resultant imaging error remains the same for both LH and RH scenarios, even though different components and machines are involved. As is illustrated in Figure 1, an estimator-based model predic-tive controller is utilized to counteract such errors. In general, measurements are provided at maximum once per wafer to update an underlying model, whereas one-step-ahead predictions and hence control actions are performed at every die in each wafer. The control signal is typically used for adjusting the position and orientation of the wafer and reticle stages to minimize RH-induced errors. When dealing with errors due to LH, lens manipulators are also involved, such as for tilting and shifting individual lens elements within the projection lens. Upon the arrival of a control command, all manipulators react

and reach to their determined setpoints almost instantaneously, and the direct influ-ence of control on outputs is modeled by means of a direct feedthrough term.

Furthermore, the predicted and measured outputs are actually not the imaging errors at the wafer level, but other key variables situated in between the initial and ultimate effects of thermal deformation. In detail, these outputs correspond to consequent displacements at particular locations on the reticle in the RH case. Thus, the deformation is characterized in terms of point-wise displace-ments that occur because of the thermal strains. Regarding the LH case, the measured and predicted outputs are the coefficients of Zernike polynomials (see Figure 2) at partic-ular locations on the exposure slit, which are used in characterizing deformation-induced aberrated wavefronts. Note that the Zernike polynomials are orthogonal on the unit disk and have physically meaningful interpreta-tions as each of them relates to a particular type of aberration. For our purpose, we have used a linear combination of the first 25 Zernike polynomials (as basis functions) to approximate an aberrated wavefront.

Research goalsMy research focuses only on the online esti-mation and prediction block in Figure 1, which inherently involves the underlying models as well. The high-level research goal of my thesis is to develop fast, recursive, and accurate esti-mation and prediction procedures for the described LH and RH problems. This assures that accurate predictions can be provided in real-time to the control mechanisms and entails accurate modeling approaches as well as suitably chosen estimation and prediction methods as subgoals.

Lens heating problem in DUV lithographyAs previously stated, the LH behavior is modeled by means of the coefficients of Zernike polynomials, which are shortly referred to as Zernikes. Each Zernike is modeled by a sum of numerous exponen-tial functions emanated from instantaneous dose injections on each die. The possible parameters to estimate are the gains and the time constants of these exponentials. For the majority of the available test cases, it is found that estimating only the gains of the exponentials is sufficient for a good

prediction performance. In this case, the esti-mation problem becomes linear and the time constants are fixed in a particular way before-hand so that they are not updated.

To improve on the mean-squared error (MSE) of this estimation problem and also to have a unique solution whenever the system is underdetermined (due to the lack of suffi-cient measurements), several Tikhonov regu-larization approaches are investigated. These involved different choices of the regulariza-tion weight. In particular, the approach that performed the best is based on minimizing the expected MSE over an ellipsoidal set that the true parameters are likely to be included. This provided around 12% improvement in prediction performance with respect to an existing heuristically selected regulariza-tion weight. In addition, the existing batch formulation for the estimation optimization has been converted into a recursive form so that computational and storage costs remain independent of time instead of increasing in time.

Reticle heating problem in EUV lithographyFor the RH problem, there are no established models and prediction methods because the current state of EUV lithography is focused primarily on achieving higher power levels with the light source to enable a high throughput and hence high-volume manu-facturing. Therefore, the modeling is started from scratch by utilizing the finite element method (FEM) on a provided geometry of the EUV reticle and several of its nearby compo-nents (referred to as chuck) that have an

impact on characterizing thermal deforma-tion in the reticle (see Figure 3). This resulted in a dynamical thermal model coupled to a static mechanical model that maps the nodal temperatures of the finite element mesh from the thermal model to the nodal displace-ments along the Cartesian axes in use. In spite of linear dynamics, the displacements depend nonlinearly on the thermal loads due to the temperature-dependent coefficient of thermal expansion (CTE) of materials.

Since FEM-based models are large-scale due to having many nodes in the mesh, model reduction techniques are necessary to simplify them to models that are suitable for real-time use. For this reason and in accordance with the structure of each model part, linear and nonlinear model reduction methods are

applied to the thermal and mechanical parts of the large-scale thermo-mechanical model, respectively. As the conclusion, the combina-tion of the proper orthogonal decomposi-tion (POD) method and the discrete empir-ical interpolation method (DEIM) is found to be the most accurate model reduction route for the treated RH problem, with the largest reduction-induced modeling error in displacements being in the order of 0.01 nm. The evaluations in this case are restricted to simulations with synthetic data, assuming a high light source power that will be realized in the coming years.

Then, by employing the resultant model in the Kalman filter (KF), the parameters of the reticle’s CTE are updated from several displacement measurements taken at the end of a wafer and, subsequently, a set of displace-ments are predicted for the dies of the next wafer. With this mechanism, the largest converged prediction error values were in the region of 0.2 nm, as can be viewed from Figure 4. This value is comfortably within the specifi-cation of 0.4 nm and, therefore, constitutes a solid ground on which the treated prediction route can be realized in an EUV tool.

AcknowledgementsAt the end of my doctoral research, I owe a great deal to many people, to whom I would like to express my heartfelt gratitude for making the completion of my disserta-tion possible and for contributing to my professional and personal development. In particular, I am thankful to my promotors prof. Wim Coene and prof. Siep Weiland. I am also grateful to prof. Paul van den Bosch, dr. Martijn van Veelen, my colleagues from the Control Systems group at TU/e and many colleagues from ASML for their crucial help and support.

The Research Centre for Integrated Nanophotonics, which has received major funding last December from the

NWO Gravitation program, combines the research efforts of the PhI and ECO groups within our faculty as well as the research from various other groups in the Faculty of Applied Physics.

It is the aim of the NWO Gravitation program to provide major funding to a small number of top research groups. The program covers all fields of science, from fundamental physics to theology. In the 2013 call 41 proposal were submitted, 15 of them were invited for an interview and from those 6 have been selected for funding. On 18 December the main applicants of the proposal, professors Meint Smit, Harm Dorren, Ton Koonen, Paul Koenraad, Bert Koopmans and Erwin Kessels, received the grant personally from the minister Jet Bussemaker.

The centre will address the challenges that result from the observations that modern society depends on the sustained steep increases in Internet bandwidth, connec-tivity and computational power for business, entertainment, comfort, safety and commu-nications. The center will focus on the tech-nology for connecting seven billion people with each other and with the data centres that will provide access to the world’s knowledge and information.

Presently, the hardware at the heart of the Internet consumes a growing amount of energy and projections are showing an unsus-tainable increase. The underlying technolo-gies are approaching a deadlock: information densities in computer and communication

systems are increasing exponentially year-by-year and moving this data around between processors already costs so much energy that designers talk of a “power wall”. The data centres powering the Internet require dedicated electrical energy stations. Energy consumption limits design and constrains connected bandwidth at every level of the network: inside computer systems, inside network routers and at the final wired and wireless connections to the user.

Photonic components and systems are the only viable technology for long-distance terrestrial telecom transport and high capacity data communications. Photons provide the most energy-efficient means of moving infor-mation. But presently energy is lost to heat in the large number of short electrical connec-tions, which occur inside computer systems, routers and at the connection to the users themselves. Information transfer from the electrical domain to the optical domain and radio-frequency connections also incur a prohibitive energy cost. A radical new tech-nology paradigm is therefore required: a pervasive end-to-end optical connection between users and computing resources and a radical enhancement in electronic-to-optical conversion efficiencies. This requires the inti-mate integration of electronics and photonics at both the system level and at the physical layer and a re-engineering of photonics close to the quantum limit. It raises formidable scien-tific and technological challenges.

The Research Centre for Integrated Nanophotonics will focus on the key hard-ware challenges in:

• introduction of photonics for transport of information at all levels of the world-wide web,

• the intimate integration of photonic circuits with electronic CMOS circuits,

• the ultimate control of light-matter inter-action.

It is the successor of the National Research Centre (NRC) Photonics, a large research programme in which the COBRA research institute of TU/e received 60 M€ funding in the 15-year period from 1999-2013. That funding made it possible for COBRA to become an internationally leading insti-tute in the field of optical communication technology with the world’s best university cleanroom for photonic integration tech-nology. The new project includes 3.5 M€ for investments in advanced equipment and funding for 27 PhD students and 11 post-docs. Approximately half of the PhD students will be appointed in the ECO and PhI group at Electrical Engineering.

In addition to the Zwaartekracht programme “Integrated Nanophotonics”, our department is also involved in an other

successful programme proposal, namely the Zwaartekracht programme “Networks”. “Networks” involves mainly a consortium of mathematicians and computer scientists. It is led by prof. Michel Mandjes of the University of Amsterdam (UvA), and has 11 applicants. Other participating organizations are the Centrum Wiskunde en Informatica (CWI), University of Leiden, and TU/e. Participating faculties in TU/e are W&I (profs Mark de Berg, Sem Borst, Onno Boxma, Remco van der Hofstad, and Johan van Leeuwarden) and EE (prof. Ton Koonen). The consortium gets about 23 million € from NWO for this 10-years programme, of which about 10 M€ comes to TU/e.

“Networks” is about solving the imminent problems of large networks, which are growing to ever larger sizes and are getting ever more complex. Our society is heavily dependent on the reliable behavior of all kinds of networks; e.g. energy networks, tele-communication networks, the internet, road transport networks, railway networks, etc. “Networks” is about trying to understand the behavior of large complex networks of which the load is varying in several respects, such as intensity and frequency, deterministically and stochastically, with varying cost func-tions, etc. The growing complexity makes these networks hard to control and sensitive for stochastic fluctuations. It is of vital impor-tance to understand how these networks behave under various circumstances; if

networks collapse or suffer from heavy congestion, vital parts of our society may get paralyzed. “Networks” will bring together algorithmic and stochastic methods for this. This approach is unique in the world.

The involvement of EE in Networks is mainly through the theme Communication Networks, in particular by contributing regarding the physical boundaries of the network optimization. EE is actually the only non-mathematical partner in “Networks”, for addressing the physical aspects. A key question is how control algorithms can be devised to dynamically regulate network traffic, how to integrate local models for network nodes into global models for the whole network, and how queuing theory can support to control traffic congestion. Optical communication networks with optical nodes are a challenging topic here.

They can operate with multiple wavelength channels within a single fibre, and an optical network node has next to time and space a third dimension, namely wavelength, for internal traffic switching. On the other hand, photons are much harder to store than elec-trons, hence buffering is an issue in optical networks. Some buffering is feasible by using recirculating fibre loops, but this can offer discrete storage times only. So the optimi-zation of optical communication networks may use the extra dimension of wavelength, but also has a tight boundary condition by its limited queuing possibilities. Another challenging topic is the routing and load balancing in fibre-wireless communication networks, which have to serve numerous wireless mobile devices roaming across radio pico-cells. Dynamic traffic allocation among those cells is then needed, offering capacity-on-demand and considerable improvement of the energy efficiency (note that mobile communication is exploding, leading to a fast rising energy consumption). Optical fibre feeder networks to the numerous radio antenna stations allow such dynamic alloca-tion by means of their signal transparency and multi-wavelength routing capabilities. A related topic of interest comprising chal-lenges of similar nature is the field of energy networks, in particular the distributed nature of functions in smart grid networks.

We do look forward to a fruitful and inspiring cross-disciplinary cooperation with our math-ematical colleagues in “Networks”.

For those who are not familiar with ASML, here’s a brief explanation. ASML in Veldhoven makes lithography

machines for the production of computer chips. The company supplies all major chip manufacturers in the world - such as Intel and Samsung - with products that defy the limits of what is scientifically possible. For instance, with the latest generation of machines, ASML is able to print lines and components less than 20 nanometres. That is like printing a complete novel of 500 pages on one centi-metre of a human hair!

Are you a man or a not? Yide: “I did my master’s internship at Philips Semiconductors (now NXP). There I worked on the design of ‘novel’ receivers, i.e. chips for mobile phones that receive and transmit data signals - such as GPS, 3G, and digital TV - to headphones and screens. It was both a fun and a difficult time. As a graduate, you’re often left to your own device. Yes, you have theoretical knowledge, but in practice, things may sometimes be completely different. Internship supervisors have limited time

so you’re on your own. I have regularly told myself: Yide, are you a man or a mouse? You always have to be able to motivate yourself.

More excitingAfter my graduation I went to work in a small IC design house. But I felt trapped in the academic environment. At Philips I had discovered a new world. I wanted something more exciting, something that puts you right in the centre of the real world. At that time, ASML was looking for many engineers. So I sent them my resume and it didn’t take long before I was called by a recruiter. The very first interview was immediately very interesting. I was impressed by the open and spontaneous atmosphere. The people at ASML are very accessible. All went very fast, a week later I was working for ASML!

Many-sided jobSince 2008, I have been working at the Application and Business Support depart-ment. We advise our clients on and support them in the effective use of our machines. It is a profession with many aspects: trouble-shooting, advising, marketing and sales. In fact, we occupy a position between

Development and the customer. When ASML has a new product, we usually introduce it in a pilot at the customer(s). We implement and monitor the entire process: testing and evalu-ating the results and analysing what benefits the product brings to the customer in terms of, for example, productivity, efficiency and quality.

Across the world For my work, I have to travel the world. The job I have is about people and the best results are achieved through face-to-face meetings. We call that customer intimacy. Your IQ and EQ are constantly put to the test. The point is that you have to be skilled at anticipating the customer’s mindset. And you have to know how to deal with cultural differences. For instance, we have many customers in Asia, and that’s when my roots stand in good stead. I also regularly go to the U.S. It is a multicul-tural environment and that is also reflected in my team. There are 8 nationalities in our team of 16 people.

BrabantEindhoven is one of the reasons why I have chosen ASML. You celebrate carnival here! The first year I experienced carnival, I thought: hey, this is the best celebration ever! The Brabant culture is very easy-going, which quite appeals to me. You can just gas along with anyone. And that’s also in the DNA of ASML.

‘From IC design to customer intimacy’By: Yide Zhu

Somewhat of a decade ago, Yide Zhu moved from the metropolis of Shanghai to the Dutch city of Delft to study electronics. On Sunday, he got off the train and found himself in a (small) deserted town. “It was a culture shock. I expected to see the kind of ideal image of tulips and cows that I used to see on Chinese TV. What I saw, was altogether different.” After a Dutch language course, Yide started his training and ultimately gained a Master’s degree in microelectronics (Integrated Circuit design). It brought him his current position at ASML. Not in design, but as the spider in the web at the Application and Business Support department.

I Advertorial

Internship JapanBy: Gerald Drenthen

After arriving in Japan I took the train to Kusatsu in the Shiga Prefecture. Kusatsu is a relatively small city without

any touristic highlights; the advantage of Kusatsu is that the cultural capital of Japan, Kyoto, is reached within twenty minutes by train. My apartment was right next to the OMRON Industrial Automation facility. My internship assignment mainly consisted of a competitor’s research, for which I had to use and understand the automation products of OMRON and afterwards compare them to those of their competitors. After completing this assignment I did some other, smaller assignments like; creating a plugin to observe an Ethernet protocol used and developed by OMRON and assisting in a current project to improve an existing product.

During my internship, the assignment was not the toughest nut to crack, instead the language made communication very chal-lenging. Of course, my Japanese language skill is and was nonexistent, but I did not expect that most of my Japanese colleagues spook poor English. After some time I adjusted my English and learned some Japanese words that allowed me to exchange small talk. However, to engage in an in-depth discus-sion was nearly impossible. A small question

could easily result in half a day spent trying to communicate, not only because of the language was a problem but also because it was hard to find someone with the knowl-edge to answer my question. Even a relatively simple question could only by answered by an expert in that field, which I found hard to believe. I think that my colleagues were too afraid to give an imperfect answer and there-fore refused to give it.

During the weekends I tried to go out as much as possible. I went out with some of my colleagues every other weekend and we usually went to dinner followed by karaoke. Karaoke with my Japanese friends is like no other karaoke I ever experienced. So much fun! The weekends when I did not meet up with my Japanese ‘nakama’ (the Japanese word for friends) I was either stuck in my apart-ment because one of the many typhoons I encountered was raging the country, or I was visiting Kyoto. Kyoto is one of the most beau-tiful cities in Japan, if not the most beautiful, and having the opportunity to explore this city at my one pace was marvelous.

After my internship I still had one month time to travel through Japan. In this time I stayed at Kyoto and Tokyo to explore the cities and their surrounding touristic attractions. Tokyo, with a size of greater than the Dutch province Utrecht, is a magnificent metropolis where I especially enjoyed the weird and famous Japanese pop culture. This is in huge contrast with the traditional culture found in Kyoto.

I will always cherish those four months in Japan as a unique and important part of my study period. Having the opportunity to do such an awesome thing as a student is amazing. Therefore, I want to encourage everyone to do an internship abroad.

In the summer of 2013 I went to Japan for four months to do an internship at OMRON. My internship lasted three months, leaving me more than enough time to travel in one of the most beautiful and interesting countries I visited so far. Because this was my second time to visit Japan, my first encounter with Japan was during the Satori study tour, I already experienced the Japanese culture to some extent. However, there was far more to learn, see, and do!

Just like the god Thor wouldn’t be able to do his work without his trusted warhammer Mjölnir, our association would be nowhere

without the similarly named file server. The importance of Mjölnir is underlined in one of the youngest stories of the 13th century Poetic Edda manuscript: the almost fairytale-like Þrymskviða, or “Lay of Þrym.”

It was still dark when Thor awoke. A god he might be, but that didn’t mean he didn’t have to suffer those nuisances of a common human’s work. The chicken needed feeding, his estate’s vast fields seeding and his wife Sif had been nagging on about cleaning the house for weeks. But worst of all, there had been sightings of a giant near Asgard’s1 outstretched walls. If it was a spy, a Jötunn2 attack would be imminent. It would be wise to be well armed these days.

The god reached for the small table where he was wont to place his warhammer Mjölnir. Not feeling anything however, he looked in shock at the table where his eyes confirmed his hammer was missing.

A few days later, a messenger appeared at Asgard’s gates. He told the gods he came from the court of the giant Þrym, and that it was he who had stolen Mjölnir. In return for the hammer, Þrym demanded no less than the beautiful goddess Freyja’s hand.

Quickly a meeting was called, and Thor opened: “My magic hammer is the best weapon of all of Asgard. It is vital to our defence. If it isn’t returned, we don’t stand a single chance against the Jötnar! I’m sorry, Freyja, but I fear there is no other option than to wed Þrym.”

“Never!” exclaimed Freyja. “Never in my life will I marry that ugly brute!”

“Doom is sure upon us if we don’t get my hammer back,” Thor replied. “Without Mjölnir to protect us, we won’t last long. Ask your-self this, Freyja, would you rather live as this giant’s spouse, than not live at all?”

“Then let me ask you this in return: would you rather live a shameful life as little more than a slave to those you detest the most, or die with glory and honour? My answer is clear.”

“It’s not just your life that’s at stake, it’s all of our divine race! If you don’t marry Þrym, all of Asgard will be drenched in blood. Blood that is on your hands!”

“And who was it who lost your hammer in the first place? How can it be my fault, when it’s you who doesn’t properly guard his belong-ings? No, my conscience is clean. If you want your hammer back, go get it yourself. But do not expect me to wed Þrym!”

“But it’s impossible to get it myself! Without my hammer I’m not a much better fighter than any strong Jötunn. And don’t forget that one of these Jötnar now has a formidable

weapon. Without Mjölnir I will not be able to even enter Þrym’s dwelling, let alone get close enough to him to even see my hammer!”

“Perhaps there is a way,” said the sly Loki. “Just think about it: Þrym expects us to attack any moment now, so he’ll let no-one except his closest friends and allies near him. That is, no-one except for one person...”

“Well?”

“Freyja. The only way to catch him off-guard is to send him the thing he expects the most. Kind of ironic, isn’t it? As Þrym’s fiancée, Freyja can gain access to Mjölnir. Once she has it, she can use it to kill the giants.”

“Well, nice idea,” Freyja said, “but you forgot one thing: I won’t be able to kill them. I’m not a warrior! I know a spell or two, but that won’t do me much good when I’m up against so many. And Mjölnir won’t be of much help either: I simply lack the strength to wield such a heavy weapon.”

“That, my dear, is why I was talking about you in the third person. ‘Freyja’ doesn’t necessarily have to be you. Thor will go in your place! Lend him one of your dresses and a veiled hood. Covered from head to toe, the Jötnar will not be able to see it isn’t you.”

“I’m not dressing up as a woman!” Thor roared.

“I fear you have no choice,” Loki said and all the other gods agreed.

“But you are the master of deception here! I’m not much good at that, they’ll see right through me in minutes!”

“That’s why I’m coming with you as your maid. I’m a good shape-shifter, even my voice will be indistinguishable from a real woman’s. And don’t forget, the giants are not the smartest of races. They will be fooled.”

It took seven days of journeying until finally Þrym’s borough came into view. The gods rode up to the gates, where a sturdy looking guard greeted them: “Hail travellers! Who seeks to enter Þrym’s palace?”

“It’s Freyja and her maid,” Loki answered. “My mistress came to wed the noble Þrym.”

“Ah yes, my master was expecting you. Please come in. I’ll show you to your rooms while the cooks prepare a wedding banquet like you’ve never seen!”

Not long after, the guard returned and took both women to the dining hall, where Þrym greeted and welcomed them.

“Ah, the beautiful Freyja! Ever since I first saw you, I knew there would be no other woman in this world for me, but you! If you only knew how much joy it brings me, to receive you in my humble dwelling for nothing less than our wedding! But please, the dinner will be here any minute now, would you care for some wine or mead? There’s plenty, so please drink some!”

Thor went straight for the nearest cask of mead and gulped it down in its entirety. After that, another cask followed, and another one, until no less than nine were empty.

“Wow, I’ve never seen a woman drink that much! Or anyone, really, except for the toughest of gods and giants!”

Before Thor could answer, Loki intervened: “That’s because no matter how much she would have drunk the past seven days, there was nothing that would be able to quell her immense thirst for you. That’s why she decided she’d just as well not drink at all. So much did she long for you!”

“Ah,” answered Þrym, “Makes sense I guess. After all, what brings greater joy, than to wed someone as rich and beautiful as I? But look, the dinner is just arriving!”

Thor grabbed a whole roasted pig, and within seconds the beast was reduced to a mere pile of bones. An entire ox and a couple of salmons soon followed.

Þrym had been looking on with wide open eyes. Even before he could express his amaze-ment, Loki saw his puzzled face and quickly explained: “She’s so hungry because of her excitement for wedding you. She hasn’t been able to get any food down her throat for seven days. So much did she long for you!”

“Never will you be hungry again, when you’ve wed me! I’ll buy you nothing but the very best food that Jötunnheim can offer!” Þrym called out, and leaned towards Freyja’s face to kiss her. But when he lifted her veil and saw Thor’s piercing eyes, he flinched. “Why do your eyes look so angry? Aren’t you glad to see me?”

Once again, it was Loki who answered: “Freyja is tired after the long journey. She couldn’t sleep for seven days, so much did she long for you!”

“That explains! Anyway, I’m finished eating. Anyone still wants some?” And when no reply came, Þrym continued: “Then let the wedding begin!”

Þrym gestured a servant to bring him Mjölnir, and according to the Old Norse wedding custom, placed the hammer in the bride’s lap. When Thor’s fingers once again felt the weapon’s cold steel, a broad smile ran across his face as he threw off his veil. Þrym never noticed, as before his brain could register the sight, it lay splattered all across the floor along with his crushed skull.

Loki had meanwhile drawn his sword, and together the two friends quickly killed the remaining giants. With the gods now safe again, they returned to Asgard, but not before they had found Þrym’s large treasure.

Thor is getting dressed up as Freyja.

56th Dies ThorBy: Stefan Molenschot, Dies committee

Opening 56th Dies e.t.s.v. ThorOn November 28th 1957 the ‘Elektrotechnische Studievereniging Thor’ was founded. Last year, Thor had its 11th lustrum, with lots of activities. Now we celebrate its 56th birthday with a few small activities, because our students are very busy and we didn’t want to take too much of their time. We started off with a pie reception. Everybody was welcome to take a piece of pie and some coffee. It was a great gathering of members and staff to have some conversa-tions and enjoy a total of 30 pies.

ACCI TAGThe ACCI Thor Assassination Game is the annual armed battle in the Dies week. All participants are given a weapon of mass

destruction. The objective is to seek out the target on your target card and take them out with a shot of your deadly rocket twice. Towards the end of the week, tensions rose and the battle intensified. The hallways started to turn into conflict zones and the Thursday afternoon Signals lecture was a true battle-field. As soon as the lecturer announced the break I (red.: Stefan Molenschot, winner of the TAG) jumped up and took out my first target. By chance I knew my target’s target, situated 2 rows in front of me, and took him out as well. I quickly moved on to target number three and scored 3 hits within a 15-minutes break. As it turned out, I killed the most targets (5) and won the TAG. The grand prize was the massive ‘BaPow!’ cannon, the title of Thor Master Assassin and everlasting glory.

CantusIs there a better way to prove that we have not forgotten how to party than a cantus? No! That is why we started the Dies with a cantus. The Praesidium was formed by Nick Janssen, Willem Burger, and Clemens Cals, who managed to maintain order in the corona, the wild bunch of singing and drinking people. Nevertheless, some measures had to be taken to maintain this order. This resulted in several punishments, often performed very well.

In the end the casks of beer were emptied and the throats were hoarse. Despite several attempts to seduce the corona to extend the

duration of the cantus, the Praesidium had to conclude the time had come to put an end to it. Satisfied everyone went home to get all the rest they could before the next day of the Dies.

Workshop Brunel: Job interviewOf course a Dies week needs something like a guest lecture. In this case a workshop Job interview. Brunel came by with three of its employees to teach us the basics of having a job interview, the “do’s and don’ts” so you will. A lot of things, like be on time, dress appro-priate, be open, all seem obvious, bust lots of things can go wrong when you’re not really prepared. We learned that every job interview will be different and there are a lot of different approaches, but when you figure out the right way to deal with it, you will get the job.

Flux tourNext year around this time of year we will be moved to another building. So let’s check out where we will be studying next year. We took a tour to some floors of the building. First

impression: a big grey concrete block with a lot of holes. We saw the new lecture room and the roof of the labs. In the new building Thor and “het Walhalla” will be located on floor 6, along with Odin, Waldur and IEEE. We couldn’t go to floor 6 yet because it wasn’t safe to go there, but next time we take a tour we can visit floor 6. They are using some very interesting and advanced techniques to build “Flux”, but they are too difficult to explain. I think in the end, when the building has been finished, it is going to be beautiful.

Beer bikingSitting on a bike, wearing warm clothes and gloves, a beer in your hand and singing along with music is usually reserved for carnaval. You might have guessed that this was no ordinary bike. Enthusiastic students traversing through Eindhoven on a beer bike was one of the Dies activities. A beer bike is a pub on wheels and, apart from the pedals, does not remotely resemble a bicycle. We took the touristic route through the center of Eindhoven. Cycling through Eindhoven, many cheered for us. Some even rode along and asked for a beer, which we happily gave them. When we reached our destination, the kegs of beer nearly ran out, perfect timing. Everyone clearly enjoyed this somewhat different

activity. This kind of activity is certainly one that can be done again somewhere in the future. I would like to thank all participants that made this activity so much fun to do.

Jailblock 56To celebrate Thor’s birthday a theme party was organized on the 28th of November. Jailhouse Rock was the theme, after the Elvis movie, which appeared also 56 years ago. A whole evening of swinging to the groove in the Walhalla, which was changed to ‘Jailblock 56’. There were songs from the time of Elvis and the Johnny Cash recordings from inside Folsom Prison, which were completely worn out at the end of the evening.

Thor and the Walhalla together donated a total of five kegs to keep the inmates occu-pied. Also a mobile chips deliverer made sure everybody got some food to party on. It was a great night with all the inmates, such as Elvis

and the Beagle Boys (‘zware jongens’). After all that fun nobody wanted to leave anymore. They all got institutionalized.

ACCI Hangover BreakfastAfter the Dies party, with an afterparty on “stratum”, the Dies committee rose from its grave very early to clean up the Walhalla in time for the Hangover Breakfast. The ACCI prepared a rich breakfast for everybody who had a hangover from the night before, which satisfied all the needs of these hungry students. Eggs, bacon, cheese, and coffee is all a student needs after partying all night. Thanks on behalf of all students with a minor hangover.

Dies DinnerTo end the week of festivities, many members and former members gather for the tradi-tional Dies Dinner. It starts in Het Walhalla where they come to congratulate the board and each other on another successful year and to toast to the birthday of Thor.

After that, we went to a restaurant in Nuenen where we were treated to a Brazilian-style barbecue.

This meant lots of meat fresh from the grill and it was perfect for satisfying all the hungry Thor members. Accompanying the meat was a choice of salads and side dishes and of course a good amount of beer and wine.

To end the evening, we went for the tradi-tional ‘Rondje in De Vooruitgang,’ except that café De Vooruitgang is closed now so we moved to Café Centraal to toast one last time before going to bed to rest from an amazing week full of fun.

An internship in JapanBy: Celine Vincent

Working at a Japanese company

Omron, a Japanese company with offices all over the world, including in the Netherlands, offered me an

internship in Japan. I would work for the R&D department in Keihanna, the region that is located in central Japan, between the cities of Kyoto, Osaka, and Nara. My assignment mainly revolved around a parallel link robot that needed better vibration control at high speeds. I had to develop a way to estimate masses and vibration parameters, without disassembling the robot. The most chal-lenging part of my internship was however the constant difficulties in communication. From my previous visit to Japan, I knew that the level of English is extremely poor. However, I reasoned, the English skills of engineers with university degrees working at a multinational company cannot be all that bad. Turns out, I was wrong.

My first day at the office was quite the experience. Everyone stared at the strange European girl with the massive suitcase walking by their desks. I was introduced to the team members I would be working with for the next three months, remembering not a single name. During lunch, while I was trying

very hard to ignore the loud slurping noises my boss was making, everyone was looking at me to make a fool of myself while dissecting a fish with chopsticks. I discovered all commu-nication was done in Japanese, including all announcements, the lunch menu, the emails and the manual for using the printers. That first day, I mainly tried to change the display language of the notebook I would use from Japanese to English, without much success. In the evening I was shown my apartment for the next three months by someone who spoke only Japanese and someone who spoke some strange mix between English and Japanese that was perhaps even harder to understand.

Cultural differencesFortunately, the days after that, I got used to the strange accent and talking with my colleagues became easier, especially with the occasional help from Google translate. Slowly, I started getting used to the daily life of working in Japan. The differences that made me laugh at first, soon made me rethink my own culture. A striking example is the morning ritual. Every morning at nine

o’clock sharp, every one stood up, recited the company motto (in Japanese of course) and bowed to the boss’ desk. It seemed foolish at first, but my boss explained that it helps create a bond between employees and ensures everyone is reminded of the core values of the company. And before long, I was reciting the motto in my best Japanese along with everyone else.

They say Japanese people are hard workers, working late every day. Although I was told that I was not allowed to work late, all my colleagues stayed after work. Some even worked on Wednesday evenings, despite the fact that Omron has a “no overtime” policy on this day. I learned that the most polite thing you can say to a Japanese worker is: “Otsukare sama deshita,” which translates to: “You sure are looking tired,” from all the hard work of course. In the commuting train, the people who weren’t staring at me, the strange foreigner, were trying to catch a few extra minutes of sleep. And I discovered it is completely acceptable to sleep during lunch

When you hear the word “Japan”, what comes to mind? Is it maybe manga or Mount Fuji, the skyscrapers and neon of Tokyo or the peace and quiet of the many shrines and temples? For me, it was sushi, something I was not overly fond of three years ago. But then, I was fortunate enough to join the Satori Study Tour to Japan in 2011, and I discovered that the country of the rising sun has so much more to offer. Three weeks is definitely too short a period to see this amazing country, so when I got the opportunity to do my internship in Japan, I immediately said yes. This is what followed.

breaks, presentations and meetings, although you have to give the impression you can wake up at any time to make a good remark.

Living the Japanese lifeWhen not working, I tried to see as much of Japan as I could. Soon, I made friends with whom I would go sightseeing in the week-ends. I visited beautiful temples not featured in my Lonely Planet. I hiked up and over mountains; actual mountains, not the glori-fied hills we have in the Netherlands. I got the opportunity to take a shot at Kendo, the Japanese art of Zen archery. You see, the benefit of having Japanese friends to show you around is that you end up in amazing places you would never have discovered on your own.

This is especially true for restaurants. I have been taken to a yakitori restaurant, where they gave me chicken liver, fried chicken skin and raw chicken. I ate nabe with pieces of cow stomach, a delicious type of hot pot dish, in a four-story building that required you to walk through the kitchen to reach the second floor. My supervisor invited me to his house to teach me how to make okonomiyaki, a type of savory pancake which literally translates to “baked as you like it”. And, despite being warned, I even tried some fermenting soy beans with a very disturbing smell and taste called natto. And here I was, thinking sushi is the strangest thing the Japanese eat.

Japan in a nutshellThe country seems one big contradiction. East meets west everywhere you look. High-tech and religion live together happily; I even saw a Shinto shrine with a Facebook and

Twitter account. Instant noodles and carefully made and decorated dishes are both typical Japanese cuisine. You have the enormous cities like Tokyo, Yokohama, and Osaka, where there is neon light everywhere. They never sleep, with everything from karaoke bars to convenience stores open 24/7, but public transport simply stops around midnight. And when you take one of those punctual trains out of the city, you will find yourself in the

middle of mountains and forests. But shrines and temples can be found anywhere: both at the top of mountains or on the top floor of shopping malls, and of course in Kyoto, once the capital of Japan, with its rich history and over 2000 temples and shrines.

Even the seasons are radically different from each other. In 2011, we visited in late winter. We saw snow, bare trees, and yellow grass, but also beautiful plum blossoms, giving us a sneak peek of the beauty of spring with its famous cherry blossoms. Now, I arrived in summer and I found a completely different country. It was very hot and humid, but beau-tiful green trees provided shade. Lotus flowers were in full bloom, and the sounds of the cicadas drowned all other noises. Soon, the typhoons began to come, marking the end

of summer. Somehow, they seemed to bring their downpours and strong winds only in the weekends. The weekdays had often beautiful weather, I noticed from my desk. And then, autumn truly came. The entire country colored red and yellow, and everyone, including me, became obsessed with the hunt for the best pictures of the most beautiful trees. The best season of them all, according to my friends, and I couldn’t agree more.

Back in the NetherlandsNow that I am back in good old, flat, no-nonsense Holland, I can only say to everyone who is not sure whether they should search for an internship abroad: go for it! You are bound to have the time of your life. The cultural differences, the people and the country will add so much more value to your experiences, that it will be the best choice of your life. There is only one problem about doing your internship in another country; at some point you will have to come home again. But you will return with new friends, wonderful memories, funny stories, lessons learned and, probably, thousands of pictures.

The differences that made me laugh at first, soon made me rethink my own culture.

Arno: vol energie over TenneT Door: Arno Haverkamp

Arno Haverkamp is in 2013 afgestudeerd aan de TU/e in Electrical Engineering. Tijdens zijn studie was hij bestuurslid

van Thor. Sinds 1 januari 2014 neemt hij deel aan het Young Professional Program bij TenneT.

Traineeship“Mijn traineeship duurt twee jaar en is verdeeld over drie perioden van acht maanden, waarbij ik in drie verschillende projecten bij drie organisatieonderdelen van TenneT werk. Gedurende het programma word ik begeleid door de programmama-nager van het Young Professional Program in mijn ontwikkeling en inhoudelijk door de begeleider van mijn opdracht.

Na mijn stage bij EirGrid, de Ierse TSO, wist ik dat ik verder wilde in de energiewereld en ben ik voor mijn afstudeeropdracht bij TenneT terechtgekomen. Hier heb ik me bezig gehouden met een studie naar het effect van de verkabeling van de nieuwe Randstad 380 lijnverbinding.

Daarna ben ik doorgestroomd in het Young Professional Program. Mijn eerste opdracht is voor de afdeling Corporate Asset Owner en gaat over de Visie 2050. Daarin wordt gekeken naar de Europese energiebehoefte in 2050 en of Europa zelfvoorzienend kan zijn in haar energiebehoefte, daarbij rekening houdend

met doelstelling vanuit de EU om de CO2 uitstoot met 90% te verminderen en om mini-maal 40% van de energie op te wekken uit duurzame bronnen. Met de uitkomsten van deze visie wil TenneT de toekomstige inves-teringen op een dusdanige manier uitvoeren dat er ook in de toekomst nuttig gebruik van gemaakt kan worden. Ik houd me specifiek bezig met de het actualiseren van de getallen en kijk naar de te verwachte groei van photo-voltaic (PV) en de rol van opslag.

Waarom TenneT?TenneT neemt als TSO haar verantwoordelijk-heid naar de maatschappij. Als we doorgaan zoals we het nu doen, hebben we over een aantal jaar te weinig energie, dus er moet wat gaan gebeuren. TenneT wil en zal deze veran-dering faciliteren en ik wil daar een bijdrage aan leveren. Met die uitdaging heb ik me gespecialiseerd in de energietechniek.

Ik ervaar TenneT als een organisatie waar veel mogelijk is. Ik ben breed georiënteerd en twijfel of ik de puur technische kant op wil of toch liever kies voor het wat bredere werk. Ik vind het wel heel leuk om met energie bezig te zijn en energietechniek vind ik interessant. In het traineeship krijg ik de kans te kunnen zoeken naar wat ik het leukst vind: ik ben nu met de Visie 2050 meer beleidsmatig bezig en hier heb ik minder een technische achter-grond voor nodig. Mijn volgende opdracht

wil ik meer technisch insteken om zo een beter gevoel te krijgen wat er mogelijk is. Bij de derde en laatste opdracht wil ik dan een mooie mix maken van de dingen die ik leuk vind.

TenneT als werkgeverTenneT is voor mij een energiek bedrijf met uitdagingen waarin internationale samenwer-king een groeiende rol speelt. Mijn collega’s zijn altijd bereid mij te helpen en praten met passie over hun vak. Naast de drie opdrachten is hier veel mogelijk, zo ben ik bestuurslid bij JongTenneT waarvoor ik regelmatig excursies en lezingen voor mijn collega’s organiseer.

Het Young Professional Program biedt mij ook een uitgebreid opleidingstraject aan waarin ik mijn persoonlijke vaardigheden, kennis van de TenneT organisatie en projectmanage-mentvaardigheden ontwikkel. Daarnaast zijn er hier nog elf andere young professionals werkzaam, allemaal mensen van ongeveer dezelfde leeftijd en achtergrond, die tegen dezelfde problemen aanlopen als ik. Wij hebben veel contact met elkaar en kunnen elkaar helpen.

Advies voor Thor ledenIk kan (bijna) afgestudeerden aanraden je goed te bedenken naar wat leuk vind. Praat met mensen en kijk breed. Als je een beetje weet wat je wil, is er hier bij TenneT heel veel mogelijk.

TenneT is de eerste grensoverschrijdende elektriciteitstransporteur van Europa. Met 20.000 kilometer aan hoogspanningsver-bindingen en 36 miljoen eindgebruikers in Nederland en Duitsland behoort TenneT tot de top 5 elektriciteitstransporteurs van Europa. Hun focus is gericht op de ontwik-keling van een Noordwest-Europese ener-giemarkt en op de integratie van duur-zame energie. Taking power further.

I Advertorial

For the first excursion of this year, ODIN travelled to the Erasmus Medical Center to learn about hyperthermia and related

medical applications.

We were welcomed by Daniel de Jong with an introductory movie about external beam radiation therapy using linear accel-erator machines. Following this we were welcomed by Gerard van Rhoon, head of the Hyperthermia Unit, who explained to us the general objectives of his department. While striving for technological innovation, patient welfare comes first and has the highest priority in every design aspect of new medical applications.

Current treatment methods, such as radiation therapy, chemo therapy and surgery lead to an overall patient survival rate of over 55% after five years. The survival rate is slowly increasing because of research performed by the Erasmus MC and comparable research centres all over the world. New developments include a radiation machine mounted on a large robot arm to enable three-dimensional radiation therapy and the combination of conventional treatment methods with hyper-thermia to increase cancer cell breakdown and repair.

As presented by Maarten Paulides, chemo- and radiation therapy is most effective on well-vascularised cancer cells. To increase the effectiveness on not so well vascular-ised cancer cells, hyperthermia is applied to

increase blood flow. Current research includes ways to increase the precision of hyper-thermia to be able to heat the cancer above 44 degrees Celsius, the current limit.

Steven van de Water introduced us to proton therapy, which is likely to be the future cancer treatment technology. The body penetra-tion characteristics of protons show a more uniform distribution. Therefore protons are more likely to hit cancer cells instead of healthy cells than electrons. Ultimately this leads to a higher radiation dose to the cancer and therefore better treatment. Challenges include patient positioning to make sure that the exact planned position is hit, this is especially important when aiming for cancer cells near vital organs like the spine, heart or brains.

René Verhaart presented us the automated hyperthermia treatment planning software that is developed by the Hyperthermia Unit. Six hours of work by a radiation therapy specialist are replaced by one hour of computing time with this software. New developments include avoidance of critical body parts by including risk analysis into the planning. The goal of this software is to streamline patient treatment and shorten

the time between analysis and treatment so minimal changes will have occurred in between these two steps.

The last presentation of the day was by Wouter Numan, about MRI guided hyperthermia. The general idea is that hyperthermia therapy is applied while a MRI scanner measures the effect on the patient. The MRI data is used as feedback to increase the accuracy and further increase temperature. Research includes a MRI compatible applicator and ways to apply MRI measurements and hyperthermia at the same time.

Concluding the Erasmus MC excursion was a tour of the facilities where the current and newly developed hyperthermia machines were shown and demonstrated. We were also able to see the internals of a linear accelerator machine that was down for maintenance. A technician was able to provide us with exten-sive details about the machine and was also happy to show us all the internal parts and bits while providing detailed information about their functions.

The Erasmus MC excursion was very inter-esting and we would like to thank the Erasmus MC Cancer Institute for their effort.

Je propedeuse in één jaar halen heeft zo z’n voordelen. Wat dacht je van getrakteerd worden op een uitje door de faculteit? In

de laatste week voor het kerstreces zijn alle eerstejaars studenten Electrical Engineering en Automotive (generatie 2012) die hun P uiterlijk in augustus 2013 op zak hadden, door het faculteitsbestuur uitgenodigd om een avondje te gaan karten en eten bij Hezemans in Eindhoven. Ook de studenten (generatie 2010) die hun Bachelordiploma Cum Laude hebben gehaald waren welkom. Aangevuld met de decaan, de opleidingsdirecteur en de drie studieadviseurs van de faculteit waren hiermee twee teams van ieder 18 personen klaar voor de competitie. En een competitie was het! Via een training en een heuse kwali-ficatie konden de snelste 18 coureurs zich plaatsen voor de finale. De overige coureurs mochten zich nogmaals bewijzen in een troostfinale.

Wie ooit gekart heeft weet dat het er best stevig aan toe kan gaan. De karretjes hebben een topsnelheid van een slordige 50 km/u en op een binnenparcours van 652 meter met flink wat bochten en nog meer hanengedrag waan je je dan ook met regelmaat op een echt racecircuit. Wil je echter niet actief aan al dat geweld deelnemen dan is er altijd nog een mogelijkheid om als een echte zondagsrijder het parcours te verkennen, mits je maar van de ideale lijn wegblijft en je de meer fervente coureurs niet dwars zit. Onze groep had in ieder geval één chauffeur in die categorie.

Dan de uitslag. In de grote finale leken de favo-rietenrollen weggelegd voor Bas Scheepens en Pieter van den Boom, die beiden tijdens de kwalificatie toptijden hadden neergezet. Wil je echter tot grote successen komen dan zul je zo nu en dan een risico moeten nemen. Het risico dat Bas tijdens de finale nam was helaas net iets teveel van het goede en na een spin op de baan ging underdog Joep Linssen er met de winst vandoor. Koen Loonen snoepte

de tweede plaats weg, net voor Pieter die toch nog derde werd. Saillant detail hierbij is dat laatstgenoemde tijdens de prijsuitreiking niet gekust wenste te worden door de pitspoes, die hierdoor zichtbaar aangeslagen was. Koen en Joep hadden er minder moeite mee.

Ten slotte is het nog zeker de moeite van het vermelden waard dat onze eigen decaan Ton Backx de bronzen plak in de troostfinale in de wacht heeft kunnen slepen. Proficiat!

PCB etching workshopBy: Bram Witteman

As a follow-up on the PCB design course, Volundr organized a PCB etching course. Every hobbyist’s dream is

to design and build his/her own PCBs and Volundr made that dream come true. PCB etching is not somethitng you do at home for

one PCB, so this course was a good alterna-tive to make your own PCB. You could etch a design you made yourself or you could use a design that Volundr made for you. So every-body could participate in this course despite not having a design.

There are many ways to etch a PCB. Volundr chose to use toner-transfer. Toner transfer is using heat to transfer the toner from photo paper to the board. When toner is transferred from the paper to the board, the board is etched using an etching liquid like hydro-chloric acid and hydrogen peroxide. After three minutes, the copper is partly dissolved and the design is visible on the board. After cleaning the PCB, because hydrochloride acid and hydrogen peroxide isn’t good for you, it is time to drill the holes. The only thing left now is to solder the components to the board.

This course was a good way to get in touch with actually making a PCB. Because PCB etching isn’t something you do every day. There were so many enthusiastic students that Volundr organized two session and both were a great success. Of course there were some people who failed to get the toner from the photo paper to the board, but in the end everybody had a nice PCB to show their parents.

I Department & Association

On Friday, November the 15th, a delegation of about 25 Master and PhD students, associated with DSD

Waldur, went on a trip to Damen Schelde Naval Shipbuilding (DSNS) in Vlissingen. DSNS was founded in the year 1875 and in 2000 became a member of the Damen Shipyards Group, which is known worldwide for its shipbuilding, both in the naval and commercial sector. DSNS is specialized in the design and construction of naval vessels and complex commercial vessels. As the supplier of naval surface combatants and auxiliaries to the Royal Netherlands Navy, the yard has carried out over 50 years of continuous frigate and auxiliary vessel development, which has resulted in seven generations of frigates and four generations of auxiliary vessels.

The main reason for this excursion was the Joint Support Ship (JSS), which arrived August 2013 in Vlissingen. The hull was built in Romania and then towed to DSNS for further construction. The ship is designed for the Royal Dutch Navy and with its length of more than 200 m, it will be the largest ship in their fleet, accommodating up to 300 crew members. It will be used for replenishing and fueling at sea, sea basing, strategic transport and disaster relief. The ship has a diesel/

electric propulsion system that generates up to 25 MW of which 18 MW is used for propul-sion at full power.

The day started quite early in Eindhoven from where we departed to Vlissingen. Although it was stressed by Waldur that passports

were necessary due to security, we had to wait for some board members because they had forgotten their passports themselves. At DSNS we received a warm welcome with several interesting presentations about the company Damen, the JSS and its tasks, and the design challenges of the electrical grid needed in the JSS. One of the most inter-esting parts is the high requirement on the robustness of the ship. Since it is a naval ship, it still has to be functional even if up to half of the systems are destroyed. Another unique requirement is that the ship cannot leave any recognizable electromagnetic signature behind to avoid detection by hostile ships or sea mines. These requirements have some major implications on the design of the elec-trical infrastructure.

After the presentations we had a nice lunch before we went on the ship. We got an extensive tour and a good impression of the immense size of the ship. We passed 600 km of electrical cables and saw the generators, which they were being tested as we walked by. We also saw the bridge, decks, propulsion systems, and even the galley.

Afterwards, we took our goodie bags and went back to Eindhoven for some well deserved beers at the Walhalla and a nice dinner at a Greek restaurant.

Het is 19 december als in het hoofdge-bouw de huldiging van Solar Team Eindhoven plaatsvindt. De dames

en heren die anderhalf jaar lang hebben gewerkt aan de realisatie van hun droom, ’s werelds eerste gezinsauto op zonne-energie, krijgen de verdiende lof toegezwaaid. Alle kopstukken van de universiteit zijn uitgelopen om de feestelijke bijeenkomst bij te wonen en de consensus is duidelijk: dit is de manier waarop de Automotive studententeams van de Technische Universiteit Eindhoven moeten presteren. Succes is een absolute voorwaarde en overwinnen moet altijd het doel zijn.

Laat er geen twijfel over bestaan dat buiten-gewone prestaties van de studententeams in iedere competitie zeer welkom zijn. Naar mijn mening zijn ontwerpcompetities gigantische PR-machines voor de TU en is er geen betere manier om de jeugd te enthousiasmeren voor techniek. Je hoeft dan ook niet lang op de Open Dagen rond te lopen om te proeven wat voor impact het succes in de World Solar Challenge heeft gehad op scholieren. Om echter nu te eisen dat ieder Automotive

studententeam zijn concurrentie voorbij streeft en gaat domineren, lijkt een voorbeeld van wishful thinking.

Want, hoe vervelend ook, het staat buiten kijf dat de TU Eindhoven nog niet bij uitstek de ideale omgeving is om je te vestigen als studententeam. Hoewel Solar Team Eindhoven met Stella een ongelofelijk knappe prestatie heeft neergezet, laat het ook precies zien waar de TU/e nog moet groeien. Zo is er bijvoorbeeld, op het moment dat Stella gebouwd moest worden, uitgeweken naar de hal van een van de sponsoren. Op de campus zelf was geen knappe ruimte te vinden die voldeed aan de eisen van het team.

Waar in Delft al sinds de oprichting van DUT (het URE van Delft) vol wordt ingezet op de studententeams, zijn de faciliteiten op de campus in Eindhoven nog niet opti-maal. Als het doel van ieder team is om Wereldkampioen te worden, moeten de voor-waarden om dergelijke prestaties te leveren ook aanwezig zijn.

Gelukkig wordt er hier en daar al gewerkt om de faciliteiten te verbeteren. Met de stra-tegische pilaar Smart Mobility en de studen-tenteams als drijvende kracht worden nu gelukkig de eerste stappen gemaakt in een proces dat al veel eerder had moeten worden ingezet. Laten we hopen dat de stilte voor de storm met de wereldprestatie van Solar Team Eindhoven definitief voorbij is.

Solar Team Eindhoven heeft laten zien hoe groot de potentie van Eindhoven als Automotive stad is. Met Stella heeft het team aangetoond dat de regio vol zit met bedrijven die hun stempel drukken op de Automotive industrie. En hoeveel kennis en expertise de Universiteit aan boord heeft in iedere disci-pline die een rol speelt in de ontwikkeling de moderne auto. Ik hoop dan ook van harte dat binnenkort alle Automotive teams hun potentie kunnen gaan waarmaken en daarbij kunnen profiteren van niet alleen de kennis, maar ook de faciliteiten en onderlinge samen-werking die de Universiteit te bieden heeft.

Winning spiritDoor: Tim Gerth

2013 was een bijzonder jaar voor de Automotive tak van de Technische Universiteit Eindhoven. Het Bachelor programma slaat aan en de eerste generatie studenten is inmiddels bezig met de eerste BEP’s. Met Stella als nieuw uithangbord en exponent van het interdisciplinaire systeemdenken, breekt een belangrijk tijdperk aan. De Technische Universiteit Eindhoven weet weer wat winnen is en moet nu doorpakken om dergelijk succes te overtreffen.

Tim Gerth is derdejaars bachelor Automotive student en mede-oprichter TU/ecomotive.
