Frequenza non obbligatoria, ma fortemente consigliata

La valutazione consiste in un colloquio orale in cui lo studente dovrà dimostrare: - la sua conoscenza degli argomenti trattati, - la sua capacità di articolare il discorso in maniera logica e rigorosa, facendo uso di terminologia appropriata, - di saper giustificare tecnicamente le sue affermazioni.

Traditional face-to-face, with supporting computer simulations.
