Teaching methods
The course is taught with the use of PowerPoint slides, available at iCampus. The lecture course also includes demonstration software and the use of interactive material. Exercises are provided to facilitate the understanding.
Evaluation methods
oral exam with a written preparation. It includes two theoretical questions: one with and one without a written preparation (15 points). The practical part is examined by the engineer, Dr. Koen Robeyns, and is evaluated with a maximum of 5 points. One more point students can get for the creative home work (the task is given).
