  • surname, first name,
  • e-mail address,
  • matriculation number,
  • course of studies (e.g. Wi-Ing),
  • desired week day for the lab (Wednesday or Thursday), and

to the E-Mail adress This email address is being protected from spambots. You need JavaScript enabled to view it.. Please note, that the registration period starts the 31.03.2017 at 8:00 am and ends the 06.04.2017 at 12:00 am. All applications before and after this registration period, will not be taken into account. Wishes concerning the weekday and the group partners of the lab will be accepted and tried to be considered, but can not be guaranteed.   

The announcement of the students successfully registered to the lab, will be until the 07.04.2017 6:00 pm or earlier, if the course is already occupied. A list of all registered students, the group assignment and the day of their lab will be announced here in the section Details.

The first experiment takes place on the 12.04.2017 and the 13.04.2017 in the PC Lab of Building B. The corresponding documents will be distributed at the beginning of this first experiment since there is no preliminary work required. The schedule of all experiments and the group assignment can be found in the list below.

  • On Wednesdays: 14:00 - 18:00 h
  • On Thursday: 14:00 - 18:00 h

New PhDs in the DSS Team

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 ...
