Societies worldwide are searching for greener and more sustainable energy systems where renewable energies increasingly play a crucial part. Special interest is taken in the sea as an enormous wind source as offshore wind energy comes to the fore. Due to its growing importance, the social impact of offshore wind farms is studied, and its social ene...

The goal of this thesis is to study the electromagnetic waves in the frequency range from 3 Hz to 2.2 kHz generated by the power distribution lines and devices connected to them. These emissions were measured using a magnetometer specifically designed for this purpose, together with the data acquisition system and signal processing, among others. E...

This paper describes the characteristics of worldwide scientific contributions to the field of electric vehicles (EVs) from 1955 to 2021. For this purpose, a search within the Scopus database was conducted using “Electric Vehicle” as the keyword. As a result, 50,195 documents were obtained through analytical and bibliometric techniques and classifi...

The stability of the power grid's frequency is crucial for industrial, commercial, and domestic applications. The standard frequency in Europe's grid is 50 Hz and it must be as stable as possible; therefore, reliable measurement is essential to ensure that the frequency is within the limits defined in the standard EN 50160:2010. In this article, a...

Sustainability is becoming of vital importance in project management, and a life cycle assessment (LCA) can ensure a body of knowledge to bear in mind the environmental burdens the project involves. In this study, two different ways of supplying energy to a sensor network are analyzed. Firstly, we analyze the environmental impact of the devices con...

The Teaching Innovation Project "Design of Printed Circuit Boards (PCB)" was created as a tool to solve the gap that had been detected in the Degree in Industrial Electronic Engineering at the University of Almería, between the skills that students must acquire and the mechanisms available to achieve those skills. An analysis of the design cycle of...
