Since January this year we have two new PhD students in the team: Elke Warmerdam and Finn Spitz.
Elke is from Amsterdam and she works in the neurology department in the university hospital in the group of Prof. Maetzler. Her research topic is movement analysis of patients with neurologic disorders. Elke cooperates with us in signal processing related aspects of her research. Elke plays volleyball and goes everywhere by bike.
Finn is working on speech analysis and therapy improvement for Parkinson patients. In his research hearing aid devices are of specific importance. Finn is a motorbike rider (Kawasaki ER6F) and does karate since about 10 yeas.
The DSS team looks back on a very interesting and also very successful year. We would like to thank all who have contributed to that: our students that did or do their Bachelor or Master theses with us, our Hiwis, all cooperation and project partners, all people who helped in educational or adminsitrative manner and of course all those that are not mentioned before. Last but not least: very special thanks to all the PhD students that "tranform" a group of very clever and nice people to a really great team ("vom Besten das Besondere").
We hope that all of you will have a nice Christmas celebration, that you will enjoy the few days that are usually free of work and that you have also a good start into the new year. Let's see what 2018 will bring to us.
On November 24th, one of our DSS team members, Owe Wisch, took part in the "Jugend forscht Perspektivforum" at the CAU. Thirty young students from the "Jugend forscht" project came to Kiel and participated in three different workshops focusing on career paths in maritime climate protection. Owe Wisch from our chair lead one of the workshops and presented his research topics, beamforming techniques and his career decisions so far to the students aged between 16 and 20 years.
We hope that we were able to show the students interesting career paths, share our knowledge about digital signal processing and its applications and hopefully some of them will consider studying electrical engineering, maybe even here in Kiel. We believe that exchange of ideas with the next generation of students, who are interested in science, is very important to the university and our chair and we would like to thank "Jugend forscht" for this opportunity.
Last Thuesday (21.11.2017) we put our first DSS boat for the first time into water. Even if it is not yet christened (to be done soon), we will call it "MISSy". This is an acronym standing for MIMO-SONAR System (thanks to Alexej for creating that name).
MISSy was able to carry three of us and until now we don't have an engine, meaning that we drive it as a bike with muscle force. However, everything was o.k. with MISSy. Now, we will extend it in several ways over the winter time. Our next steps will be an extension for our trailer, as well as artifical SONAR targets, communication and localisation possibilities.
We would like to thank our colleaques from the WTD 71 / FWG for finding an appropriate boat for our purposes and also for their "helping hands".
Recently, Owe Wisch finished his master thesis on speech recognition for swimming googles. The idea was to recognize commands such as "play", "stop", or "pause" while wearing an MP3 Player within the water.
In order to achieve that goal, Owe Wisch added several microphone within and on the outside of typical swimming googles. He used a GMM-based recognizer to map the "bubbling speech" onto several commands. The playback of was done via so-called bone conduction speakers that were also mounted on the side of the googles.
Special thanks to Jonas Wilinski who created the video that you can find below.
This fall Jens Reermann left the team after finishing his defense (see last news entry). At the same time - meaning in October/November - three new people entered our team.
Rasool Al-mafrachi was the first one. He came over from Bagdad / Irak with his family (his wife and his son) in October. Rasool will work on in-car communcation - supporting our speech and audio "division". Afterwards Christin Bald and Owe Wisch joined our team at the beginning of November. Christin will continue the work of Jens (medical signal processing with emphasis on magnetoelectric sensor systems). Owe is our third "underwater guy" - he will focus on communication aspects in SONAR systems.
We are very happy that these three clever, smart, intelligent, ... but also very kind - and that's the important thing - guys joined our group. Welcome to the DSS team.
On Friday, 21st of June, Jens Reermann defended his research on signals processing for magnetoelectric sensor systems very successfully. After 90 minutes of talk and question time he finished his PhD with distinction. Congratulations, Jens, from the entire DSS team.
Jens worked for about three and a half years - as part of the collaborative research center (SFB) 1261 - on all kinds of signal enhancement schemes for the new types of magnetoelectic sensors that are built by the material science researchers here in Kiel and used by our medical colleagues in the universtiy clinicum in Kiel. Jens implemented a real-time system for noise cancellation as well as a digitally contrlled analogue carrier suppression scheme (in cooperation with HF group) - to mention just a few a his contributions.
On June 30st, Chirstin Bald and Thorben Kaak were honored with prices form the Faculty of Engineering. Christin Bald finished as the best bachelor student this year in the study program "Electrical Engineering, Information Technology and Business Management" and Thorben Kaak did the same but in terms of his master studies in the study program "Electrical Engineering".
Of course, the DSS team congratulates both of them to the price and to their excellent performance during the study periods.
In June Alexej Namenas started in the DSS Team. He will work on real-time tracking algorithms for SONAR applications. Alexej has done both theses (Bachelor and Master) with us. The Bachelor thesis in audio processing (beamforming) and the Master thesis in the medical field (real-time electro- and magnetocardiography). In addition, he has intership erperience in SONAR processing.
We are pretty happy that Alexej has joined our team. Beside him also his twin brother (Anton) is in our team. Currently, we can easily differenciate both, since Alexej has done a lot of weight lifting recently. However, Anton joined the gym now as well ...
Recently the second part of the special issue on "Smart Vehicle Technologies" appeared in the IEEE Signal Processing Magazine. The issue was jointly edited by John H.L. Hansen, Kazuya Takeda, Sanjeev M. Naik, Mohan M. Trivedi, Gerhard Schmidt, Yingying (Jennifer) Chen, and Wade Trappe.
We were pretty happy to convince a large group of authors to write very interesting contributions. Since the contributions were too much for a single issue, the publishers agreed to do a double issue. Our introduction for the special issue can be found here.
As mentioned earlier, the month April was very "productive" in terms of PhD outcome for the DSS team. Tim Claussen defended his research on April, 28th successfully. Now we have five new doctors this month.
Tim Claussen has investigated and implemented SONAR systems with special focus on real-time MIMO approaches. Beside theoretical investigations he also implemented all approaches in our real-time system. Beamforming, adaptive Doppler analysis and cognitive approaches were among the various contributions that he worked on.
Tim, congratulation from the entire DSS team.
This April is very "productive" in terms of "PhD generation". On April 20th and 20st we had another two PhD defenses within the DSS team. First Vasudev Kandade Rajan defended successfully his research on (speech) signal processing for microphones that are integrated in seat belts. The very next day Jochen Withopf gave his "PhD talk" on in-car communication systems - also very successful.
Vasudev Kandade Rajan has investigated and implemented a multi-channel (for a multitude of loudspeakers, phone channels, and microphones) hands-free system. Special emphasis was put on the support of so-called belt microphones (sensors that are integrated in the security belts of cars). The project was done in close cooperation with the company "paragon". Vasu, congratulations from all of us!
Jochen Withopf has done research on so-called in-car communication systems, both in terms of theoretical analyses and practical implementations in our research cars. Jochen has worked in close cooperation with the Daimler. Also for you Jochen, congratulation from the entire DSS team.
Special thanks go to Prof. Dr. Tim Fingscheidt and Prof. Dr. Rainer Martin for being the second reviewers of the two PhD defenses.
Finally we should mention that April is not yet over. Let's see what the remaining week of April will bring.
