Depending on the future PoliTo decisions related to the Covid-19 situation evolutions (in case of new future waves), the possible impacts on this course and its organisational issues will be reported on the "Portale della Didattica" in the page of this course

The course is organised in: - lectures (54 hours) - practice lectures (27 hours) aimed to apply the sizing concepts also to support the students in acquiring the expected evaluation abilities

Lesson slides will be distributed through the Polito Website as pdf files to be used ONLY for the module purposes. Some valuable complementary reading materials are: - F.

Exam: Computer-based written test in class using POLITO platform;

The exam is in written form only and consists of three parts (each of them counting for one third of the final mark): - Part 1: 48 true/false sentences - Part 2: 24 multiple (4) choice sentences/questions (each question has just one correct answer) - Part 3: 8 fast numerical exercises on electrified traction systems sizing (the numerical exercises require to solve numerical problems similar to those shown during the practice lectures) Duration: 3 hours. During the exam it is possible to use just a simple scientific calculator (or the calculator available in Respondus interface), a pen and white papers. Exchange information among students is not permitted by any means. Use of multimedia devices such as cell phone, tablet, pc, smart watch is not allowed. Use of any written material such as notes, textbooks or equivalent materials is not allowed. Students have to attend the exam at Polito site using their own computer

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
