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

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.

LEARNING OUTCOMES: This course aims at providing the fundamentals of fluid dynamics applied to fluid machines. More in detail, it deals with the fluid dynamics equations applied to energy-consuming and energy-producing machines, characterized by both axial and radial flows. It also deals with the understanding of systems connected to fluid machines.

KNOWLEDGE AND UNDERSTANDING: The student will be able to develop simple but useful calculations of fluid machines in terms of flow, work and power, along with solving practical problems of interest. The student will also learn the basics of the control of fluid machines with respect to the flow rate, work exchanged and power output or input The knowledge developed will help the student for both the design of fluid machines and of the systems connected to the machines.

APPLYING KNOWLEDGE AND UNDERSTANDING: The student will apply the knowledge and understanding developed to the analysis of practical problems. This would imply critical knowledge in terms of size and power output/input; the same thing will be done for the systems connected to the machine.

MAKING JUDGEMENTS: The student will have to prove his critical awareness with respect to the simplifying assumptions useful to describe and calculate fluid machines, as well as his critical awareness of the correct order of magnitude of performance parameters while dealing or designing fluid machines.

COMMUNICATION SKILLS: The student will prove, mostly during the oral test, his capacity of describing the operation and functioning of fluid machines, convening of the knowledge developed.

LEARNING SKILLS: The student will get familiar with the schematization of practical problems, mostly during the development of his skills for the written test. This mainly concerns fluid machines (e.g. wind turbines, steam turbines, hydraulic turbines, hydraulic pumps, gas compressors, etc) and the systems connected to the machines (e.g. hydraulic power plants, pumping systems, air distribution systems, etc).
