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 mechanical and energetic fields. The acquired knowledge are useful to all the professional figures that involve the mechanical engineer in the analysis, verification and control of machines and systems performances. The ability to analyze experimental data, to define and analyze measurements, especially obtained through digital acquisitions, are fundamental in any industrial context. For example, in the automotive industry these capabilities are fundamental both for whom is involved in the development and calibration of the systems (engine control, traction, ...), and for whom use experimental measurements to validate theoretical and numerical models.
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.

Applied lectures (10h) During the applied lectures the student will solve practical exercises concerning the experimental data analysis, 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(30h) The students will extensively work with virtual laboratory based on a notebook, Arduino boards and a breadboard. 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 Boards connected to some devices (LCD, SD Card reader/recorder, …) will be used like a DAQ in order to perform simple experiments. The breadboard allows the realization and test of simple conditioning circuits based on Operational Amplifiers.

The breadboard allows the realization and test of simple conditioning circuits based on Operational Amplifiers. In addition, the Laboratory work will be focused on three activities where the students must define their acquisition chain, acquire the experimental data end analyze them. A report for each of these activity must be written and handed in. The reports will be evaluated by the teacher and the evaluation will account for the final mark of the exam.

Modalità di esame: Prova scritta (in aula); Prova orale obbligatoria; Elaborato scritto prodotto in gruppo;
Exam: Written test; Compulsory oral exam; Group essay;
The exam consists of: practical, written and oral exams*. Practical test (1.5 h): The student has to develop of an electronic circuit on a breadboard and a sketch for the Arduino Uno board. The evaluation is: 13/30 for the electronic circuit and sketch handed in and positively tested in 1h; 10/30 for the electronic circuit and sketch handed in and positively tested in 1.5h; a maximum mark of 5/30 for not working electronic circuits and sketches. Written exam (1.5h): the student has to solve three exercises, which have a value of 5/30 marks each, concerning statistical data analysis, electronic circuits analysis and DAQ setup. Oral exam: it deals with the theoretical topics covered during the lectures; it provides a maximum mark of 6/30. The final mark is the sum on the mark obtained in the practical, written and oral exam*. *Oral Exam is mandatory to pass the subject. The student can attend the oral exam only if the sum of the marks obtained in the practical and written tests are higher than or equal to 12/30.
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.

Attended results. The exam want to check the capability of the student to design a measuring chain by selecting suitable transducers and properly setting a DAS, and to post-process the measured quantities. Therefore, it checks the student knowledges about the following topics: - capability to select of a proper transducer in accordance to the characteristics of the physical quantity under investigation; - capability to design simple electronic circuits for electrical signal conditioning (amplification, filtering); - capability to configure the acquisition chain and set the acquisition parameters (sampling frequency, trigger type, Anti-aliasing filter); - capability to critically analyse and post-process the measured data (uncertainty estimation). Esam procedure. The exam consists of: written and oral exams. Written exam (1.5h): the student has to solve three exercises, which have a value of 10/30 marks each, concerning statistical data analysis, electronic circuits analysis and DAQ setup. It provide a maximum mark of 30/30 and the student can sit to the following Oral exam if the Written exam test evaluation is higher or equal to 15/30 only. Allowed material during the 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 deals with the theoretical topics covered during the lectures with particular reference to the discussion of the written test, the reports related to the laboratory activities and to the transducers performances and selection. It provides a maximum mark of 30/30. Exam final evaluation. The final mark is the weighted mean between: - Written test: weight 45% ; - Oral Exam: weight 45%; - Applied lectures reports (evaluated during the course): weight 20%. Therefore, the maximum contribution of the reports evaluation to the final mark will be lower or equal to 6 points. A final mark higher than 31/30 will be registered as 30 with honor.
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.
