The purpose of this article is to provide a short and practical manual regarding the vast and complex field of technical standards in electrical engineering and electronics. In particular I will talk about the rules adopted by qualified bodies and recognized nationally and internationally and produced by the contribution, the consent and approval of all parties involved such as designers, installers, manufacturers, consumer groups, the competent authorities
This article will be a useful support for all those who directly or indirectly are involved in their use, especially for all those people who are going to make the happiness of many children getting ready to illuminate trees, nativity scenes, balconies, facades, gardens ( Fig.1 shows some examples of Christmas decorations bright)
In these times when energy saving is very timely especially with the realization of equipment increasingly attentive to the consumption of electricity, with this article I want to focus on that dot always on, usually red in color, which represents the stand-by of almost all modern electrical and electronic equipment; a bright dot that is generally considered annoying but completely harmless
With the passing of years and the continual technical development of materials and components, the electrical system in civil buildings, and not only has integrated its role as a simple distribution of electricity with modern technology Home and Building Automation (HBA), better known by the term Domotics. This word is composed of a set of words: “domus”, which in Latin means house, and “robotics” the discipline of engineering that deals with methods that allow a machine to realize the human labor.
The Technical Consultant, generally referred to as Court Appointed Expert Witness (CTU in Italy), is a professional with specific technical expertise that acts as the assistant to the judge during the civil trial. Instead (referring only to Italy) if he acts in a criminal trial he is referred as Perito tecnico d’ufficio (PTU).
Over the course of my career as a designer of electrical systems and technical manager of various companies, I have often heard, especially from the experts; The mains voltage is 220 volts, or you receive documents with units of measurement incorrectly written, incomplete and sometimes even completely incomprehensible.
Atlab is an application that we all know, but we are not always aware of all its potential. In fact, Matlab in addition to carry out the numerical calculation directed to which we are all accustomed, also allows us to evaluate analytically (i.e. maintaining parametric expressions) Many of these calculations. In fact, thanks to the symbolic Math Toolbox, Matlab provides us with a set of instructions for symbolic (or literal) computation.
