Back to business

It is a week since the successful ELCA festival (don’t tell me you haven’t seen the pictures yet; they are below) and everything has gone back to normal again. Mark is trying to convert the videos taken to manageable sizes (watch out as some may be posted on YouTube in due course), photos have been distributed and it is more or less business as usual.

2057 the bodyDon’t get me wrong here; this is still more exciting than an ordinary day at the shop. Marijn and Christos are making the final preparations on the uStim, our flexible neurostimulator, which soon will be tried out in vivo; Wannaya and June are working very hard on the circuit design and layout generation of the analog bionic ear; Marcel is working towards the completion of his PhD thesis and having the forms filled in to also publish it as a book — the first on Structured Design of EMI resilient analog circuits; Senad is wrapping up the simulations on a L2-optimized wavelet filter, to appear in a paper currently under review for prospective publication in IEEE Transactions on Circuits and Systems; Duan is designing a proof-of-principle experiment of the world’s first subsampling jitter-compensated software defined radio; Andre is trying to improve the efficiency of an RF energy harvester for a batteryless ultra lowpower radio; Yongjia is working hard on the circuit definition of an asynchronous level-crossing ADC for analog-to-digital conversion of non-stationary signals, such as ECG, EEG, ECoG, etc; Mark is thinking about how to combine an energy harvester with an ultra lowpower ultrawideband tag, but also a little about his exciting holiday ahead; the many MSc students are working hard on their MSc project and I am working hard on my invited presentation at the International Symposium on Medical Information and Communication Technology. If you want to have a glimpse of what I will be discussing there, check out the following movie/documentary of "2057 The Body"

Reading back the above, I feel a little like Sheldon, viz. Sheldon Lee Cooper, B.S., M.S., M.A., Ph.D., Sc.D., a fictional character on the CBS television series The Big Bang Theory. I received the first three series for my birthday. So Marijn, if you wish to organize a geeky lunch break, count me, and the DVDs, in!

ELCA Festival – Even more pictures…

As must have become clear from the previous posts on the blog, the ELCA festival has been a big success. It is only two days ago, but I am already dreaming about next year’s edition!  To once more underline the success of the festival, it won’t do any harm to post a couple of more pictures…

ELCA Festival – Part II

Yes, a great night to remember! Not just because of those unforgettable songs and dancing, but we also raised money for Japan!

ELCA band Biohazard collects money for Japan at the ELCA festival

Last Friday, March 18, the Pub of the EE building of Delft University of Technology turned into a majestic rock temple. A broad spectrum of performances was offered to the audience, ranging from a clarinet concerto, via opera, flamengo, Mr. Micro, famous covers (from both the ELCA band and the ETV band) to societally engaged rock songs of Three and Ignoramus. Hopefully, Marijn, Senad and Yongjia will post some great pictures soon.

Paddy at ELCA festivalSo why the title of this blog then? Well, I was reading the thread at nu.nl about the latest situation in Japan, where the offical number of dead and lost people has now crossed 20,000 and I was thinking about an emotional Paddy at the ELCA festival, who has lived in the devastated area for quite some time and was not able to get in contact with a few of his Japanese friends over there since exactly one week. He fears for their lives and spoke the following memorable words: "You may think Japan is far away. Yes, that is indeed the case. You may think Japan is rich and should be able to take care of itself. Maybe they indeed can. However, if we were in their shoes, which is not a too unrealistic scenario since the Netherlands is threatened by water both from the see and the rivers, we would wish the Japanese would also think about us and help us." I fully concur with this.

We have not yet counted the money collected, after which we will transfer it onto the Japanese Red Cross, but if you’re reading this blog — and I know you do — and would like to make a donation as well, please do so. The bank account of the Dutch Red Cross that has been opened for Japan is 6868.

Thank you very much.

Biomedical Group Meeting today

lunchWhile enjoying lunch, the Biomedical Electronics Group gathered in the Davidse room (named after the former head of the Electronics Research Lab and also my "promotor", Jan Davidse) to listen to three presentations. The first one was by Duan Zhao, on an interesting new way of bridging the gap to low-power software radios by means of subsampling. After an introduction on the operation of a subsampling receiver, he explained to us a technique to remove the jitter originating from the sampling clock by using a harmonically related reference. Currently Duan is working hard on a manuscript to be submitted to GlobeCom.

The second presentation was by Neil Yongjia (as we call Yongjia because he will perform a song by Neil Young at the ELCA festival) on the correspondence and differences of successive approximation (SA) analog-to-digital converters (ADCs) and level-crossing ADCs. There is an interesting paradigm shift involved in the latter and many issues, such as DC sampling, bandwidth and slope limitations need to be investigated still. Nevertheless, it looks like the level-crossing ADC is a natural candidate for the conversion of physiological signals such as those that are generated by the body.

The third presentation was by Yours Truly, and was about how to turn your profession into the best job in the world. We touched upon cultural aspects, organizational aspects, academic aspects and personal aspects and things like procrastination, drive, bosses and the fun-factor. Probably in June, I will give a similar presentation to my colleagues of our faculty. 

Tomorrow will be the ELCA festical. Don’t miss it, as the world will never be the same…

Donation for the recovery of Japan

The 2011 ELCA music festical will be held on Friday, March 18th, at 19:00 hrs. Last year, it used to be an activity for people to enjoy music after a year of research. This year the theme has changed. While we were preparing for an evening full of fun, a tragedy happened. After the earthquake, Japan has been bruised again by the wave ‘Tsunami’. More than 10,000 people have been swept away. Nuclear reactors are at the verge of exploding. People in that area can hardy find clean food and water.

We cannot not just watch the news and go to bed without worrying about the Japanese people.

Then a discussion arose in our research group. "How can we help?" The result is: we will dedicate our performance at the ELCA festival this year to Japan. The price of the beer will be 10 cent higher. This is for a donation; the money we get from the drinks will go to Japanese people. We know this is not gonna be big money but every Euro counts.

Dear readers, please come to the ELCA festival in the Pub, Mekelweg 4, Delft, at 19:00 hrs. We have prepared a Japanese song for this. 

Each glass that you drink is meaningful. It is the drink of kindness driven from human symphathy inside you.

Let’s sing together for our Japanese friends letting them know that they are not alone.

See you on Friday.

BioCAS 2013 in Delft or Amsterdam?

Looking back on a successful BioCAS 2010 in Cyprus, the BioCAS Steering Committee is gradually looking forward to bids to host BioCAS 2013. Looking at the activities in the Netherlands by companies, such as Medtronic, Philips Healthcare, Twente Medical Systems, a.o., and academia in the Medical Delta, viz. Erasmus University Rotterdam, Leiden University and Delft University of Technology, the recent Dutch Innovative Medical Devices Initiatives and of course our own activities in the field of Biomedical Electronics, I think hosting BioCAS 2013 in Delft or Amsterdam would be great! I am currently ramping up the first discussions on this with prospective members of my organizing team.

One thing that we, unfortunately, cannot beat is the very fine weather we encountered at Cyprus. See the picture below of Cees-Jeroen, Mark, Marijn and Wannaya enjoying lunch at BioCAS 2010 in the bright sun. On the other hand, the Netherlands have lots of other good stuff to offer and usually the weather isn’t too bad in November. So stay tuned, to hear more about whether and how these plans come to fruition.

Neuropod: the podcast of Nature on Neuroscience

neuropodIf you, just as many members of the Biomedical Electronics Group, have a fascination for the intricacies of the human brain, you may be interested in this podcast from Nature: Neuropod.

Particularly interesting is the feature of January 2011, on why music is so pleasurable, or to find out how to treat tinnitus

Delft University of Technology (TU Delft) top rated among Dutch universities.

TU Delft ranking

According to a recent research from the Times Higher Education Magazine the reputation of Delft University of Technology is ranked as 49th among reputations of the world’s best universities. In this ranking, based on the opinion of 13.000 academics around the world, rather than universities’ performance, four Dutch universities, led by TU Delft, can be found in the top 100.

One can argue about the value of reputation ranking but in my opinion many young students will choose their university based on this subjective quality, which will lead to higher economic value for the universities.

Independent of any ranking, I am convinced that the members of the Biomedical Electronics Group will continue to contribute to the science and to society and thereby add to the value and reputation of TU Delft.

Radio silence on weblog

Dear all,

As you have noticed, not much has been posted to this weblog recently. This is most likely because most of the active bloggers of the Biomedical Group are also musicians in the ELCA band and this is the "silence before the storm", so to speak. As already announced in June’s post, the ELCA festival is upon us in (now) less than a week!

Another reason of the radio silence is due to the earthquake and successive tsunami in Japan, followed by another earthquake. Everybody held his breath when Mother Earth rumbled.
