a.Univ.-Prof. Dr. Birgit Pröll (birgit.proell(at)faw.jku.at)

Registration

via KUSSS

Schedule and Preliminary Meeting

The course comprises 6 lectures and a final exam (see KUSSS for schedule). Exrcises have to be worked on in groups up to 3 students and presented in the first 1,5 hours of each lecture. Except for the preliminary meeting and the final exam, which start at 12:00 s.t., all lectures will start at 12:00 c.t.

There might be a rescheduling replacing the lecture date from May 18 to April 27 dependent on room availabilities. In case of a re-scheduling students will be informed by email.

Presence is obligatory at the beginning of the first course => preliminary meeting, which is meant for organisational issues, decision on course participants and group building for working on the exercises. If, for arguable reasons, your personal presence in the preliminary meeting is not possible, it is requested that a colleague assures your participation in the lecture, assignes you to a group, and circulates the information presented in the preliminary meeting; otherwise your course registration gets cancelled.

Further, presence is obligatory, when presentations of exercises are scheduled. Absence (also if excused) will imply a reduction of points of the exercises due.
