TEACHING MATERIALS  AULAWEB 
The teaching provides the basic knowledge needed to understand the main physical and technical phenomena found in the design and production processes of industrial artefacts.
This course provides an overview of the different fields of Applied Physics. The aim of the course is to allow students to gradually advance to solve transdisciplinary problems through an educational path that is tailored to actual design issues. Throughout the course various issues will be covered, such as problems related to heat and mass transfer and to hygrometry, as well as analyzing light sources and artificial lighting.
By the end of this course, students will be expected to:
 know the main physical qualities of applied physics and their relevant units of measurement;
 be able to describe and study the transformations of thermodynamic processes;
 know the fundamental laws of kinematic, dynamic, thermodynamics, fluid mechanics, and heat transfer;
 be able to perform simple analyses of thermofluidynamic phenomena;
 solve simple problems relating to energy transformation, kinematics and dynamics of a material point, fluid dynamics, heat transfer by conduction, convection and/or radiation.
Students have to know properly and deeply the main topics and means of Mathematics.
The teaching consists of both theoretical lectures and applied lessons. The first ones introduce the main topics, the latter deepen the knowledge and give examples of applications.
Attendance to the lessons is not mandatory but is highly recommended to maximize the teaching impact and to ease the students’ learning.

The exam(*) consists of two mandatory parts: a written test and a subsequent oral test. The written test lasts one hour and consists of closed questions on theoretical and applicative topics. The test is meant to check if the student has/has not reached a minimum level of knowledge on the main topics. If the outcome of the written test is sufficient, the student is admitted to the oral test, which is also on both theoretical and applicative topics. The oral exam is meant to evaluate to which extent the student is able to analyze, describe and discuss the teaching’s 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.
(*) changes can be introduced according to government’s regulations about pandemic diffusion.
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.
