News

There will be no exercise in the first week of the semester (09.04.2019). The exercise will start the week after on the 16.04.2019.

Starting this semester exam procedure for Signals and Systems I will be adapted slightly. The notes on the exam execution and rules will be shortened. Instead of reading out the whole exam problems there will be 10 minutes of additional reading time. Please note that during this reading time no writing will be allowed.

Exam Results and Exam Inspection:

The results of the winter semester's exam of 20.09.2019 are online in the QIS-system. Please note the date of the exam inspection:

Date: Tuesday, 29.10.2019
Time: 10:00 h - 11:00 h
Room: Library of the DSS-group (D-037 A)

Please note that any information regarding your exam, including achieved points and "how close" you are to passing, can only be given out during an official exam inspection. Your grades will always be available through the QIS-system as soon as possible.

DSS-Retreat 2019

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 ...
