LEARNING OUTCOMES:
The fundamental purpose of this course is to provide students the necessary knowledge concerning the practical aspects of the use of measuring instruments, assembly of circuits, and the limits of the most common components and integrated circuits. It is important to observe, that the objectives of a normal course of electronics are to some extent different from those of this course. In fact, generally the goal is basically the understanding the operation of the various circuits proposed. For the experimental electronics course, on the contrary, the fundamental purpose is the synthesis or the project. In other words, choosing the right components of a circuit so that it behaves in the way you want.

KNOWLEDGE AND UNDERSTANDING:
Understanding of the practical aspects necessary for using the most commonly used measuring instruments, basic electronic configurations, and the most used integrated circuits.

APPLYING KNOWLEDGE AND UNDERSTANDING:
Ability to use the introduced measuring instruments, to design and to implement the electronic circuits examined during the course.

MAKING JUDGEMENTS:
Education for an independent evaluation, as it is necessary for verifying, through measurements, the synthesized electronic circuits implemented during the course. Furthermore, the reasoning is stimulated for the identification of all those errors in which the student may incur in phase of synthesis, implementation and measurement.

COMMUNICATION SKILLS:
The communication between the learner and the teacher is stimulated and refined during the course, as there is ample room for questions from students who need to know how to combine the theoretical and practical aspects of the proposed experiments.

LEARNING SKILLS:
The course is based on learning a series of preparatory elements. This requires the learning of a certain number of notions necessary to solve the experiments of the next lesson.

SYLLABUS

General concepts related to the use of measuring instruments present in the laboratory (multimeter, power supply, signal generator, oscilloscope).
Passive filters.
Diode circuits. Synthesis of small-signal amplifiers. Concepts related to the power amplifiers, class A, B and AB.
BJT current sources. Concepts related to sinusoidal oscillators. Structure and operation of operational amplifiers, and their applications. Structure and operation of voltage regulators, and their applications. Structure and operation of timers, and their applications.

LEARNING OUTCOMES:
Basic knowledge about manufacturing processes for metals.

KNOWLEDGE AND UNDERSTANDING:
Conventional technologies for metals are studied. In order to stimulate student’s knowledge, the interaction between material and tools is always highlighted. The student is able to analyse and evaluate any manufacturing process with a proper technical language.

APPLYING KNOWLEDGE AND UNDERSTANDING:
Thanks to the interaction between frontal lessons and laboratory activities, the student is stimulated to have an own technical profile. He will be able to manage technologies with technical language and sketch capabilities.

MAKING JUDGEMENTS:
The student develops own skills and capabilities in describing transformation processes by taking example from the frontal lessons.

COMMUNICATION SKILLS:
Students are invited to describe technologies in a proper technical way and with an adequate technical speech.

LEARNING SKILLS:
Learning skills are continuously improved thanks to the applied methodology for technology description. This methodology can be translated to any other technological process. Capabilities increase because of the number of described technologies and their correlation. Examples from the industrial world and laboratory experiments crystallize the knowledge about new technologies.

SYLLABUS:

Materials structure and properties: structure of metals, crystals, thermal stresses, solid solution, material properties, mechanical behavior, testing, and manufacturing properties of materials, metal alloys: structure and strengthening by heat treatment

Manufacturing of metals: fundamental of metal-casting, metal-casting processes and equipment, bulk forming (rolling, forging, extrusion and drawing), sheet-metal forming, sintering, fundamentals of machining, cutting-tools, machining processes (turning, drilling, milling).

Joining processes and advanced machining: fusion-welding, solid-state welding, adhesive-bonding, fastening, rapid-prototyping processes and operations, additive manufacturing.

Laboratory lessons: mechanical tests, surface engineering, hardness of metals, microscopy.

OBJECTIVES

LEARNING OUTCOMES: The course aims to provide students with the basic principles, physical laws, and applications of thermodynamics, thermo-fluid dynamics, and heat transfer, with the dual purpose of preparing them to afford more applicative courses and using the acquired knowledge for design and sizing simple components and thermal systems.

KNOWLEDGE AND UNDERSTANDING

Students will have to understand the physical laws of applied thermodynamics and heat transfer, and understand the structure and operation of the simplest components and systems. They will also demonstrate that they have acquired the basic methodologies for verifying and designing the studied devices.

APPLYING KNOWLEDGE AND UNDERSTANDING

Students must be able to afford courses for which this course is preparatory (for example Thermotechnique, or Machines) and to size or verify simple components and systems, topics covered by the course, such as air conditioning systems, engine systems, fins and heat exchangers.

MAKING JUDGEMENTS

Students must assume the autonomous capacity to face the subsequent studies for which this course is preparatory and to draw up simple projects of thermal systems that use the studied components. They will also need to be able to evaluate projects written by other parties, checking that the project requirements are satisfied.

COMMUNICATION SKILLS

Students must be able to illustrate in a complete and exhaustive way the acquired information, the results of their study and of their project activity, also through the normally used means of communication (discussion of the results obtained, report on the performed activity, PowerPoint presentations, etc.).

LEARNING SKILLS

Students must be able to apply the physical laws underlying the studied phenomena, and to face further studies that use the acquired knowledge. They will have to be able to expand the already owned information through the analysis of technical-scientific literature and to modify their curricula choosing future knowledge to be acquired on the base of their knowledge and tendency.
