On Thursday, 25th of April, members of the IHK (Chamber of Industry and Commerce) visited our DSS group at the technical faculty.

Our visitors first listened to a talk about the work of our department – real-time signal processing for sensors in the field of medicine, speech and sonar.

Afterwards we showed our guests some live demos regarding our research fields. We would like to thank our visitors for the nice evening with very interesting discussions!

Recently, we get the new projector front-ends from Atlas Elektronik for our MIMO SONAR system. This was part of the "Großgerät" which was obtained with the help of the German research foundation (DFG). Now we are able to perform underwater experiments that will show if our ideas and corresponding realt-time algorithms also works in real environments.

We would like to thank all of our partners, the DFG, the Bundeswehr (WTD71), and Atlas Elektronik for their help with respect to this very interesting underwater research topic.

On Friday, August 23re, we had our yearly summer event. The whole event started with our yearly GaS meeting (GaS stands for "Gesellschaft für angewandte Signalverarbeitung"). Afterwards, we had several talks: Robbin Romijnders, for example, presented a nice introduction into gait analysis using IUMs (inertial measurement units). Furthermore, Dr. Florian Schulz from Atlas explained various signal processing approaches that are applied for underwater applications.

After the talks we opened several of our lab doors and presented demonstrations from our underwater and medical projects. The rest of the night was filled with a barbecue and good conversations until the early morning. Hope to see you all also on next years event.

On Monday, 27th of May, CASSy - our new research platform for underwater signal processing arrived at the technical faculty. Thorben, Alexej, and Owe "pulled" her home from Wismar, where she was produced. CASSy is financed by the German Research Foundation (DFG) and, of course, we deliver a very big thank you to the DFG for the support.

Beside CASSy (the ship) we will get also a new MIMO-SONAR hardware (also funded by the DFG) that allows for new SONAR and communication modes, which we are happy to investigate in the near future.

On Tuesday, July 2nd, we did the first test of our new underwater drone at the beach of Möltenort (near Mönkeberg). The new drone is able to do high resolution unterwater pictures and videos, which allows us to see how our underwater research equipment is "behaving" below MISSy and CASSy (our two research vessels). The drone is controlled via WIFI with a remote station that swims on the water. The drone is connected to the remote station via a 50 m cable which is also the range of our "missions". Now we are prepared for the next steps with our SONAR research. 

 

On Thursday, August 29th, we tested CASSy the first time in real water. With the help of our collegues from the Bundeswehr (special thanks to Dr. Jan Abshagen and Dr. Arne Stoltenberg) we were able to put CASSy into the Baltic sea. After fixing some engine problems, we had your first "cruise" - a short trip from Kiel to Mönkeberg and back. Everything worked fine. Now, we feel confident to go on and put some "science" on CASSy for the next cruise. If you are interested you can find some more details on CASSY (and MISSy) here.

Thorben, Kevin, Tobias and Bastian extended our framework and the tools that are supporting it such that one the one hand TensorFlow is supported now and - on the other hand - that KiRAT is now fully functional also with the operating system Linux. The support of TensorFlow is important since it allows to train our models offline with this important tool, but to realize the corresponding estimations and decisions in real-time in KiRAT. Well done, Gentleman.

Last Tuesday, we decided to do our three-weekly science slam at the beach in Mönkeberg. Since it was very warm the days before we planned to combine this science slam with a picknick at the beach. However, at this specific day the temperature dropped a lot and we had really strong wind and also some rain. Thus, we did the science slam, but returned afterwards to the faculty and had our picknick there. Anyhow, it was fun to have another outside sience slam as you can see at the picture.

The last two days (Monday and Tuesday, September 16 and 17, 2019), the whole DSS team did a course on TensorFlow and Keras. Since we already have interfaces of TensorFlow to our real-time tool KiRAT, it was time now to extend our knowledge on graphs and the corresponding training of weights, biases, etc. After two days of hard work we booked two escape rooms and solved the "secrets" hidden in the rooms. It was really fun (both the TensorFlow workshop and the escape rooms, of course) and we enjoyed the time. Actually, we can really recommend this combination.

As in the last year we spent a couple of days (15.10.2019 till 18.10.2019) on the island Sylt to reflect our past, current, and future research work. Due to a "cold wave" we were a bit reduced this year, but anyhow, we had a very good (and producive) time on this beautiful island. Beside our research plans (reflecting the last year and planning of the next years), we also discussed teaching and outreach topics. Some changes on our webside will be done now and parts of it (e.g. changes in the entry page) are visible already right now.

A few weeks ago our new research car (a V class from Daimler) arrived here and now we start to prepare the van for the next level of our research on in-car communication. Since Anton is in his "second live" a very gifted carpenter he started built up the housing for our real-time systems that will be placed in the trunk. Let's see how the car will look like in a few weeks ...
