## Modalità di verifica dell'apprendimento

The course assessment will be based on a an oral exam based on the discussion of different topics presented during the course considering both applications and theoretical backgrounds.

In particular, each student will receive a homework at the end of the course and will have to prepare a written report presenting the solution of the homework and a throughout discussion of the procedure used and of the results obtained.

The report has be delivered at least 1 week before the date of the oral exam and its correction will be used to start the discussion. In addition to the discussion and correction of the report, at least another question (usually 2) will be made during the oral to complete the assessment.

The final grade will be determined considering a) the correctness and the clarity of the report (about 20%) b) the cerrectness and clarity of the discussion on the report during the oral (20%) c) the correctness and clarity of the answr to other quesiotns (60%).

In case of negative outcome of the exam, the student can repeat a single time the oral wihtout changing his/her homework, after that a new exercise will be given.

## Strumenti a supporto della didattica

The slides presented during the lesson as well as other supporting materials (solved exercises, example of reports etc..) will be made available on insegnamenti online (https://iol.unibo.it/) before the beginning of the course and during the course in case of particular needs or updates.
