Assessment methods and criteria

Assessment methods

Further information

The final grade is determined as the average of the two modules (identification and control).

Assessment criteria

The student preparation will assessed during the oral exam. The primary elements of evaluation are: - The ability to communicate in a clear and formal language appropriate for the advanced understanding of science and engineering; - the capability to demonstrate the knowledge of the material with the answer to questions in all topics of the program; - The ability to describe results of advanced scientific findings in the open literature, and the presentation of a design project in a clear, scientific manner, describing the individual effort and understanding of the problem; - The capability of showing a clear conceptual understanding of the overall engineering implications of the material presented in the course.
