The subject aims at providing the basic theoretical knowledge and practical skills to the students that would be needed to face the important technical problems in the experimental measurements of the main physical quantities in the energetic field.

As an outcome from the subject, the students should be able to understand, design and organize the experimental activities which are usually carried out regularly in University laboratories, the Industry as well as in the Research Institutes.

The students attending this subject should be acquainted with basic knowledge of: mathematics and physics; electricity and fluid-dynamics; mechanics, thermodynamics and heat-transfer. The knowledge of the "C" programming language is also useful.

The main subject topics of the theoretical and applied lectures are: 1. International System of Measurements (SI) 2. Measurement Methods and Experimental Errors 3. System Dynamic Models (zero, first and second order) and Fourier analysis 4. Basic Electrical Principles (Electrical Components, Bode Plot, Bridges, Amplifiers, Analogical and Numerical Filters) 5. Data Acquisition Systems (DAQ) 6. Instrument connections and Noise protection 7. Temperature measurement 8. Pressure measurement 9. Flow measurement

Applied lectures (4h): During the applied lectures the student solves practical exercises concerning the design of an experimental layout, the choice of a sensor, the design of a measuring chain and the setup of a Digital Acquisition System. Laboratory Lectures (20h): The students will extensively work with virtual laboratory based on a notebook, Arduino Uno board and shields. Virtual instruments like Oscilloscope, Wave Generator, Spectrum Analyser and Digital Filters will be simulated by means of software that are based on the netbook soundcard. The Arduino Uno Board will be used like a DAQ in order to perform simple experiments. The Laboratory activities are divided in there macro practical experiences and the student has to prepare a report for each of them. The reports will be discussed during the oral exam.

Modalità di esame: Prova scritta (in aula); Prova orale obbligatoria;

Exam: Written test; Compulsory oral exam;

... The exam consists of: written and oral exams. Written exam (1h): The student has to answer to multiple choice questions. Oral exam: The student is allowed to attend the to oral exam if he provided at least 60% of the correct answers in the multiple choices test. The oral exam is focused on: a) the discussion of the reports written at the end of the laboratory activities; b) the topics discussed during the lectures. In order to pass the exam the oral exam has to be higher than 18/30. The final mark of the exam is the algebraic mean between the mark of the written and the oral exam.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
