A didactic prototype to estimate the electric power produced by an angular motion

Abstract

This paper describes the design and implementation of an experimental system that estimates the electric power that can be produced by the angular motion showing the fundamental principles of mechanical-into-electrical energy conversion, which are the operation main basis of electromechanical devices such as wind turbines. Some theoretical concepts related with curricular subjects such as Electric mchenary, Physics, Renewable Energies, Power Electronics and Microcontrollers, were verified by Science students that participated in this project achievement. The main aim of this work is to show a simplified system development for didactic applications that can be mounted at indoor conditions and can be constructed from a set of basic and cheap electrical components.

Denoising of chaotic signal using independent component analysis and empirical mode decomposition with circulate translating

“…The denoising of chaotic signal based on the wavelet transform can produce a good result, [12,13] it can analyze the local characteristics of signals in the time-frequency field with a simple calculation. However, the wavelet base and the number of the decomposition level, which play an important role in the result according to the research, [14,15] must be fixed before denoising.…”
