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.

Reference Books Experimental Methods for Engineers - J. P. Holman - McGraw-Hill Inc. Measurement, Instrumentation and Sensors Handbook - J.G Webster - CRC Press (Optional) Didactic material provided by the lecturer The video of the lectures.

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.

Modalità di esame: Prova orale obbligatoria; Prova scritta tramite PC con l'utilizzo della piattaforma di ateneo;

The exam consists of: written and oral exams. Written exam (90 minutes): 1st part (30/30): The student has to answer to 15 multiple choice questions (MCQ) regarding the topics discussed in the lectures. The MCQ can provide more than one correct answers. The evaluation of the MCQ is performed in accordance to the following rules: . +2 points when all the correct answers are selected; . 0 points when none or all the answers are selected; . -2 points when all the incorrect answers are selected; . when a mixed selection of correct and incorrect answers is provided, the evaluation if performed in accordance to the above rules. 2nd part (mark 30/30): the student has to solve 2 exercises regarding the topics discussed during the applied lectures. The mark assigned for each exercise is equal to 15/30. The final mark will be evaluated as the arithmetic mean between the 1st and 2nd part. In order to pass the exam the mean value has to be higher or equal to 18/30 and the 1st and 2nd part has to be both higher or equal than 12/30. Oral Exam: The oral exam is at the sole discretion of the exam board. The board will select the students that are supposed to sit the exam depending on the outcome of the written part as well as on the Lockdown Browser feedbacks and REGARDLESS of the mark. If so, the final mark will be a proper weighted average between the outcomes of the written part and of the oral test.

The exam checks the student knowledges about the following topics: - selection of a proper transducer in accordance to the characteristics of the physical quantity under investigation; - configure the acquisition chain and set the acquisition parameters; - critically analyse and post-process the measured data. The exam consists of a written and oral exams. Written exam 1st part (30 minutes, mark 30/30): by means if the Exam platform and Respondus proctoring system. The student has to answer to 15 multiple choice questions (MCQ) regarding the topics discussed in the lectures. The MCQ can provide more than one correct answers. The evaluation of the MCQ is performed in accordance to the following rules: . +2 points when all the correct answers are selected; . 0 points when none or all the answers are selected; . -2 points when all the incorrect answers are selected; . when a mixed selection of correct and incorrect answers is provided, the evaluation if performed in accordance to the above rules. 2nd part (60 minutes; mark 30/30): in the classroom. Students can sit to the 2nd part if the 1st part has been completed with a mark higher or equal to 12/30 only. The student has to solve 2 exercises regarding the topics discussed during the applied lectures. The mark assigned for each exercise is equal to 15/30. The final mark will be evaluated as the arithmetic mean between the 1st and 2nd part. In order to pass the exam the mean value has to be higher or equal to 18/30 and the 1st and 2nd part have to be both higher or equal than 12/30. The maximum mark is 30/30. The "30/30 with honour" is provided to students after a mandatory oral exam. Students are supposed to solely use a calculator, as well as a formula sheet in A4 format to be procured by the students themselves. In addition, students can use table for Gaussian and Chi-2 distribution. Oral Exam: The oral exam is at the sole discretion of the exam board. The board will select the students that are supposed to sit the exam depending on the outcome of the written exam. Before the oral exam the selected students have to hand in the written reports for the laboratory activities; these reports would be discussed during the oral exam. If so, the final mark will be a proper weighted average between the outcomes of the written part and of the oral test.
