Modalità di esame: Prova orale obbligatoria; Progetto individuale; Progetto di gruppo;
Exam: Compulsory oral exam; Individual project; Group project;
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Compulsory oral exam; Individual project; Group project;
The mandatory oral exam will start with the individual discussion of one assigned project, regarding the simulation or experimental implementation of one digital control algorithm. Each student will produce a technical report of the respective project. The project and the report can be delivered individually or in groups of maximum 3 students. This first part of the oral exam will be evaluated with a maximum grade of 15 out of 30. If the project report is evaluated 6 or more, the rest of the oral exam will consist of two oral questions on any of the content covered by the exam. This second part will be graded 15 out of 30, as well.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
