CODE 56095 ACADEMIC YEAR 2024/2025 CREDITS 6 cfu anno 2 DESIGN DEL PRODOTTO E DELLA COMUNICAZIONE 11439 (L-4) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/11 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 2° Semester TEACHING MATERIALS AULAWEB OVERVIEW 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. AIMS AND CONTENT LEARNING OUTCOMES 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. AIMS AND LEARNING OUTCOMES 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. PREREQUISITES Students have to know properly and deeply the main topics and means of Mathematics. TEACHING METHODS 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. Students who have a valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the teacher and with the Department of Architecture and Design's disability referent (https://architettura.unige.it/commissioni_e_referenti_dipartimento).

TEACHERS AND EXAM BOARD STEFANO LAZZARI Ricevimento: Student office hours typically take place on Wednesday mornings, from 11:00 to 12:00, or at the end of individual lessons. Students must schedule appointments for office hours via email. Appointments can also be arranged for different times/days and conducted through the Microsoft Teams platform. STEFANO BERGERO Ricevimento: The dates of the revisions with students are available on AULAWEB.

The written test results in a grade that can be directly recorded. The oral exam is optional and at the student’s discretion. The written test takes the form of a multiple-choice quiz and consists of questions (both theoretical and practical), which may have one or more correct answers. To take the exam, it is necessary to have completed online registration and bring your university booklet and/or an identification document. Students who are not registered cannot take the exam. Exam registrations close by 24:00 on the Saturday preceding the Tuesday exam date. To ensure fairness and avoid negative impacts on exam organization, registered students who no longer intend to take the exam must remove themselves from the list by the same deadline mentioned above. Unjustified absences will prevent participation in the subsequent exam session. 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 ID and/or other 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 needed table / diagram will be supplied within the written test. The usage of handouts, forms or sheets other than those provided is forbidden (exception is made for DSA students). 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.
