Teaching methods
The course consists of 6 credits in two modules.
Each module includes theory lessons and/or a series of numerical examples
Assessment methods
The examination at the end of the course aims to assess the achievement of learning objectives, verifying the knowledge that the students have acquired about the coure topics.
The final grade is defined by a single oral exam, testing the student's knowledge in all topics covered in the 6 CFU
Teaching tools
Teaching material presented in class will be made available to the student in electronic format via internet.
