Teaching methods

Ex-cathedra teaching with the help of slides for the volume 1. Practical works with the assistants for the volume 2.

Evaluation methods

Exam of about an hour, about the theoretical concepts of the course (PART I) + exam of about 3 hours with practical problems to solve (PART II). For the PART II exam, students can only have a personal handwritten summary on a single, double-sided A4 sheet.
The success of both parties is required. If one of the two parties is in failure, the resulting score will be the minimum between the average score and 9/20.
An eliminatory question on very basic aspects of the course can be provided at the beginning of the exam. The final score will be 0/20 if this eliminatory question is not successful.
