MODALITA' D'ESAME

Oral exam.

MODALITA' DI ACCERTAMENTO

The exam is aimed to veirfy the acquisition of knoledge about theories presented during the course. The exam consists in an oral discussion including two main parts. Firstly the candidate has to present the exercise assigned during the course, concerning the implementation of the simplified Savitsky method on a computer program (based on excel+vba) and its application to the analysis of a planing hull selected by the candidate. The second part consists in one or two questions on topics addressed during the course.

The assessment is done during the exam based on the capability of the student to describe autonomously and consistently the topics, theories and demonstrations addressed by the course.
