Material provided by the teacher is available on AMS-Campus (Teaching Material) 
(copies of the slides, examples of exam questions).
In order to download such material, students are expected to register in the following distribution list:
The password of such list will be given by the instructor in the first class of the course. Students not attending such class are recommended to ask for the password to classmates or by an email to the instructor, reporting name, surname, university code and adding the tag [DC-pwd] in the subject.
Students are recommended to register in the list as soon as possible in order to download the material and to receive the emails about the course sent by the instructor to the list members.
List subscribers are not automatically removed, once they have passed the exam. They can remove themselves manually, using the same webpage they used to register in the list.

Remark: for some of the course topics, slides give just an overview and significant additional parts will be presented at the blackboard. For such parts, the students are expected to take their own notes or to ask classmates for notes, whether they cannot attend some lessons.

Metodi didattici

Traditional classes, supported by PC presentations (copy of the slides are available on AMS-Campus).
Some parts of the course are presented only by using the blackboard (for such parts, students are recommended to take their own notes or to ask for notes to classmates, attending classes).

Lectures in collaboration with companies and academic institutions.

Modalità di verifica e valutazione dell'apprendimento

Final written exam including theoretical questions and simple exercises.

Detailed rules concerning exam characteristics (including how to book it), marks and registration procedure are given in a pdf file in the Teaching Material on AMS-Campus. Such file can be downloaded by any UniBO student, even without subscribing the above mentioned distribution list.
