OVERVIEW

The teaching aims to provide the basic knowledge needed to understand the main physical and technical phenomena found in the design and production processes of industrial artifacts.

AIMS AND CONTENT

LEARNING OUTCOMES

The teaching provides an overview of Applied Physics, with the aim of allowing the students to proceed knowingly towards the solution of transdisciplinary problems, developing an educational path tailored to actual design problems. Problems related to heat and mass transfer, to hygrometry and elements on light sources and artificial lighting are dealt with.

AIMS AND LEARNING OUTCOMES

The teaching consists of both theoretical lessons and classroom exercises, aimed at applying the theory to specific problems. By the end of the course, the student will be able to set up and solve simple problems of mechanics, energy analysis of systems, fluid flow, transfer of heat by conduction, convection and / or thermal radiation.

TEACHING METHODS

The teaching is carried out through lectures that are all held by the teacher. Lessons can be performed by using computer presentations (powerpoint) or by using the traditional whiteboard. As an integrative teaching activity, the teaching includes classroom exercises, aimed both at the application of the theoretical notions provided and at the deepening of some theoretical aspects.

EXAM DESCRIPTION

The exam consists of two mandatory parts: a written test and a subsequent oral test. The written test consists of a multiple-choice test, lasting one hour, on both theoretical and applicative topics. If the outcome of the written test is sufficient, the student is admitted to the oral test, which is also on theoretical and applicative topics. If the oral test is not sufficient, the exam is not passed and the written test must be repeated. Booking to the exam session is via the Unige portal.

ASSESSMENT METHODS

The written test evaluates the successful comprehension of the different topics of the course and the consequent ability to apply the concepts acquired to the solution of some simple problems.

The oral test allows to investigate with more accuracy the student's level of knowledge of the theoretical and applicative themes as well as his ability in performing critical reasoning. In the oral examination, attention is also paid to the clarity of the exposition and to the mastery of specific technical language.

FURTHER INFORMATION

To join the exam, the Student must show the university booklet and an identity document.

During the written test students are allowed to use only a black or blue ballpoint pen, the necessary to erase, a ruler, the calculator. Any necessary table / diagram will be supplied within the written test. The usage of handnotes, forms or sheets other than those provided is forbidden.

All the news concerning the teaching (e.g., advices, recommendations, changes to the office hours for students, evaluations of the written tests, etc.) are always posted on the Aulaweb webpage.

Students are advised to update their e-mail address provided by the University with the address of a frequently-checked inbox, so as to receive any urgent notices communicated by the teacher.
