    Objectives

    The Distributed Real time Cyber Physical Systems course aims at providing solid knowledge and competences to conceive, define and design complex cyber physical systems  which are at the basis of emerging fields as  Internet of Things,  Smart Factories and Critical Infrastructures. In particular focus is put on the distribution and coordination aspects of the constituent systems of an SoS  and on  time management  issues.

    Exams

    Exam is organized in two distinct parts:

    1-  (Lab): the assignment is described in the section "Lab on Cyber Physical System" (see file "Final assignments for the lab exam"), a report of the work done must be delivered to Dr. Gharib and Dr. Ceccarelli a few days before the oral exam.  It will be evaluated and if the evaluation will be positive the student is allowed to the oral main part. 

    2- Theory: This part includes an oral exam by Prof. Bondavalli. 

    Please contact Prof. Bondavalli and or Dott. Ceccarelli to define exam dates.
