Objectives

Scientist and engineers need experimentation for confirming theory, computers modeling and controlling even the most elementary system. The instrumentation for measurement is fundamental in metrology, laboratory and industrial measurements, systems control and supervision. All these fields of instrumentation are taken in account in the syllabus of this one semester course of the “mestrado integrado” on mechanical engineering, although the main focus is in the domain of laboratory and industrial measurements. Some attention is given to operational amplifiers, mainly related with the common circuits used as non-inverting amplifiers, inverting amplifiers and differential amplifiers.

1 - BACKGROUND
The instrumentation for measurement is fundamental in metrology, laboratory and industrial measurements, systems control and supervision. This is a mandatory subject in any engineering course.
2- SPECIFIC AIMS
The main focus is in the domain of sensorization for laboratory and industrial measurements, monitoring and digital recording, also regarding measurement errors and uncertainties.
3- PREVIOUS KNOWLEDGE
Mathematical fundaments, Electrical systems, Solid Mechanics and Structural Mechanics I.
4- PERCENTUAL DISTRIBUTION
•Scientific/technological component: 60%
•Experimental Component: 40%
5- LEARNING OUTCOMES
•to convey metrology concepts and terminology;
•to offer a basic background in laboratory and industrial measurement principles’, metrology and procedures;
•to practice the evaluation of error analysis and measurements;
•to promote ‘hands-on’ laboratory activity;
•to develop the students’ capacity in analyzing, interpreting, criticizing and reporting results;
•to encourage student initiative and imagination;
•to make students familiar with new technologies for remote access;
•to reinforce students teamwork skills, personal responsibility, self-organizing and conflict-solving capabilities;
•to attempt to teach how to learn.

Teaching methods and learning activities

The course has been exploring blended learning methodologies, using the WebCT e-learning platform where three thematic courses are already developed and many other materials are available. Students are invited to contribute for building a glossary, which may help the sedimentary process of knowledge. Also, a set of experiments are remotely available. Materials from theoretical lectures and lab sessions documentation exist on-line. All the course information is within the e-learning platform, even the theoretical and lab schedule and the assessment criteria grid.

The course has continuous assessment of concepts and of experimental procedures and methodologies, with final written examination. There are four distinct assessment components (two mainly involving the work group performance, and two as individual assessment, either on theoretical or experimental topics). These occur in specific moments: weekly group assessment based on students' involvement and real performance on experimental tasks and results discussion; mid term individual lab assessment within experimental tasks and their theoretical background (20 min); a similar final individual lab assessment (20 min); a poster based on one chosen topic (among several defined in the beginning of the semester) is another group assessment component; finally, a written exam for testing the integration of theoretical and experimental knowledge and calculations (2h00). The mid term and final lab assessment are matched within each student lab schedule.

Eligibility for exams

Simultaneously:
Not exceed the official number of lab missing classes;
Minimum average mark on lab performance and involvement (LPI) ≥ 8,5 (20);
Weighted average of the lab assessments (40% mid term (MTLA) + 60% end of term (FTLA)) = (LA) ≥ 8,5 (20);
Poster elaboration (PE).

Frequency mark (FM) = 0,25 * LPI + 0,5 * PL + 0,25 * PE

Calculation formula of final grade

Weighted average of the frequency mark (FM) and of the final examination (FE):

Final mark = 0,7 * FM + 0,3 * FE

Special assessment (TE, DA, ...)

Written examination (WE)
Lab examination (minimum mark =8,5 (20)) (L)
