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.
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.
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 Thursday, August 15th, we participated in the "Kiel Science Walk" (Wissenschaftssapziergang) that is organized by the city of Kiel. About 20 interested people visited us. First Dr. Frank Paul in his role as the manager of our institution gave a short talk about current facts and the history of our faculty. Afterwards, our real-time time system KiRAT as well as the some (theoretical) basics of our research projects were explained. The main part of this event were then five lab demonstrations that were presented by virutally all of our PhD students. We hope that the "science walkers" enjoyed their visit in our labs. Further details can be found here.
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 ...
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.
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.
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.
On Thuesday, June 25th, about 30 pupils from the Isarnwohld school in Gettorf visited us. First a couple of Bachelor students shared their experiences about the "transition" from school to university and make some common remarks on the "life of studnets". Thanks again to the students for their help here. Afterwards we had several demonstrations ranging from medical applications over automotive to underwater signal processing. We hope that the pupil enjoyed their visit in our labs. Some more details about this event can be found here.
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 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!
The DSS team was invited to participate in the last of the "Saturday Morning Physics" (SMP) events in 2018. On December 8th, a Saturday of course, Thorben Kaak, Gerhard Schmidt, and Owe Wisch gave a talk on underwater signal processing. Pupils from all around Schleswig-Holstein were quite interested, especially in the basics of SONAR systems.
