Award for the Best Thesis in Applied Signal Processing

As part of this year's GaS Online General Assembly, Moritz Boueke, B.Sc., was awarded the title "Human Movement Classification using IMUs in Real-time" for his bachelor thesis. Mr. Boueke's work focused on the detection and differentiation of various everyday activities based on sensor data collected with inertial measurement units (IMUs). In our ageing society, neurodegenerative diseases such as Parkinson's are of high clinical relevance. In this context, the recording of movement patterns is an important tool in diagnosis and therapy. The trend is shifting from measurements in the clinical movement laboratory to measurements in the home environment, in which wearable sensors (so-called wearables) are used.

The identification of activities in the comparatively large amount of data is an important step in order to subsequently carry out targeted medical analyses, in which e.g. only stand-up processes are to be considered. As part of his work, Mr. Boueke has created extensive signal processing structures in the real-time framework KiRAT (Kiel Real-Time Application Toolkit), which lay a foundational foundation for this. This includes pre-processing of the sensor data, feature extraction, a decision tree for the actual classification and the preparation of intermediate results for visualization. As a result, activities such as "walking", "brushing" or "sitting down" can now be classified in real time with a state-of-the-art IMU system.

Neurogeriatrics, Department of Neurology, UKSH Campus Kiel, under the direction of Professor Walter Maetzler, acted as a medical project partner: "The award-winning work here is extremely innovative and user-oriented in an area that we physicians have paid too little attention to date: the natural home environment of our patients. With the presented work, Mr. Boueke succeeds in classifying relevant activities of daily life. This can be built on in many ways, with the ultimate goal of better diagnosis and treatment, especially of movement disorders. I would therefore like to congratulate Mr. Boueke and the supervisors on their work!" said Maetzler.

Congratulations from the whole DSS team.

Early Career Research Award for Patricia Fuchs

Our university awards excellent achievements of female students in mathematics, IT, natural sciences and technology (known as the MINT subjects). This year Patricia Fuchs was awarded for her Bachelor thesis on the development and implementation of a magnetic heart axis estimation. We congratulate Patricia Fuchs to the EmpowerMINT award.

The thesis was supported with technical and medical expertise. In order to be able to compare the magnetically achieved results with conventional examinations (based on ECG), test persons were examined by Dr. Daniel Körbächer in his practice in Mönkeberg. The same persons were then magnetically measured at the Faculty of Engineering. Through this new method, the heart position of patients can be estimated more accurately and also in 3D (so far, this analysis is carried out only in the body level, i.e. in 2D). Ms. Fuchs was also supported by Prof. Frey, Head of Cardiology at the Heidelberg Hospital (and also a member of the SFB 1261). Erik Engelhardt and Gerhard Schmidt supervised the work on behalf of the Faculty of Engineering.

New DSS Sign

Jannek Winter and Tim Rocholl designed and facricated a new DSS sign for us. A very nice one - see the picture. After some discussion we decided to put it on the wall in Gerhard Schmidt's office. This shows the DSS logo now in every online meeting he participates in the background. Tim Rocholl is still doing his Master courese, but Jannek Winter has finsihed his study period now and continues in idustry.

Thanks to both of you from the whole DSS team!

Podcast on Parkinson Speech Research

On Wednesday, 2nd of September, Liv Preßer, interviewed us about or research on Parkinson speech analysis and corresponding therapy. The story appeared in Liv's podcast called "Was steckt dahinter". If you would like to hear it, please have a look on this website. Beside this website there are a couple of further possibilities: e.g. search for "Was steckt dahinter" on spotify.

Beside Liv Presser and Gerhard Schmidt, also Corina Maetzler (from the geriatrics department of the university hospital here in Kiel (UKHS) and Heidi Nebel from the neurologic department (also UKSH) participated in the podcast recording. Together, we reported on our research results, the probelms that we faced when conduction our experiments and patient recordings, and on our future plans.

More details on Liv's podcast can be found here.

New DSS Member

Since July we have a new member in the DSS team. Even if the name sounds male at first glace, Toni is a "lady". She will help all of us, but in particular Patricia, to stay calm in critical situations. If you would like to make friends with her - small "Wieners" will help a lot.

Toni is a real shaker - she does about a hundred times a day and also Patricia starts doing that now. Soon all of us will shake in special occasions. Toni, a very warm welcome in the DSS team.

Workshop on Biosignals

On Wednesday the 11.03.2020 the three-day workshop “Innovative Processing of Bioelectrical and Biomagnetical Signals” started at Kiel University. This workshop is a collaboration of the two expert committees “Biosignals” and “Magnetic Methods in Medicine” of the German Society for Biomedical Engineering in the VDE. Researchers working at the interface between medicine and technology were able to present their research during poster sessions and short scientific talks. The subjects included cardiological examinations, possible applications for biomagnetism, methods to analyse movement as well as neurological biosignals. Despite the broad field of discussions, a lively scientific exchange was achieved.

The dean of Kiel University’s Faculty of Medicine, Prof. Dr. Ulrich Stephani, praised the work of the researchers, stating that no progress of medical diagnosis would be possible without technological research. This was also underlined by four keynotes given by Prof. Dr. Eckhard Quandt (Kiel University), PD Dr. Helmut Laufs (University Medical Center Schleswig-Holstein), Prof. Dr. Wilhelm Schulte-Mattler (University Medical Center Regensburg) und PD Dr. Philipp Hüllemann (University Medical Center Schleswig-Holstein, MediClin Klinikum Soltau). They provided insight in sensor systems, signal processing and diagnostic procedures within different medical contexts.

In the course of the workshop six junior scientists were honoured by the Young Investigator Award for excellent talks or posters. The best talk was given by Michael Kircher (KIT) about “Nonlinear and Piecewise Fitting of Indicator-Enhanced EIT-Signals: Comparison of Methods“. The talk about “Colour Spaces and Facial Regions for a Camera-Based Heart Rate Estimation” by Hannes Ernst (TU Dresden) was voted second best. Patricia Piepjohn (Kiel University) was awarded the third place for her talk concerning “Real-Time Classification of Tremor Patients’ Movement Patterns”. The price for the best poster was awarded to Nicolas Pilia (KIT) for his contribution about “Reconstruction of Potassium Concentrations with the ECG on Imbalanced Datasets“. The poster on the subject of “Active Shielding of Optically Pumped Magnetometer by Means of Helmholtz Coils” by Christin Bald (Kiel University) was honoured with the second place. Richard Hohmuth’s poster (TU Dresden) concerning “Applicability of Spectroscopy in Multispectral Photoplethysmography” was voted third best. The award winners will be supported in publishing their contributions to the workshop in the journal “Biomedical Engineering/ Biomedizinische Technik”.

Owing to the precautionary measures which were taken due to the corona virus, several participants could not be part of the workshop. The organisers of the event, Prof. Dr. Gerhard Schmidt (Kiel University), Prof. Dr. Andreas Bahr (Kiel University) and Eric Elzenheimer (Kiel University) concluded that they are glad to have held the workshop in spite of the corona virus and they hope that the participants could draw on the exchange with colleagues they have had during those three days for a while.

Our SONAR Simulator Supports Underwater Speech Communication Now

Due to the work of Owe Wisch and Alexej Namenas (and of the rest of the SONAR team, of course) our SONAR simulator supports now a real-time mode for testing underwater speech communication. A multitude of "subscribers" can connect to our virtual ocean and send and receive signals. The simulator consists of large (time-variant) convolution engine as well as a realistic noise simulation that takes parameters such as wind speed, etc. into account. In addition, linear and non-linear behaviour of the sending and receiving hardware can be simulated. However, no simuator is of course as beautiful as the real sea.
