[EN] The use of active power filter is recommended to reduce the effect of harmonic current components in the electrical distribution network. By means these power converters, power quality indexes can be improved: THDi, ...

[ES] El trabajo consiste en la obtención de un método rápido, aproximado y sencillo, de la obtención de los valores de la inductancia y del condensador con un factor de rozado del 5%, que pondríamos en una instalación donde ...

[EN] The mouthpiece of an instrument is a fundamental part for the instrumentalist. Not only is the choice of instrument range important, but the choice of mouthpiece can be even more important. One of the decisions to be ...

[EN] This paper presents an IEEE Std. 1459 power magnitude measurement system working as a part of a power quality improvement structure. It is intended to enhance the performance of selective shunt active power compensators ...

A summary of Music Theory is presented and it is shown how it is integrated in the Musical Abacus. As well, answers are given to several questions that usually arise when one begins to study Music. To do it, a diagram is ...

[EN] The propagation of intense acoustic waves in a periodic medium (sonic crystal) is numerically studied. The medium consists in a structured fluid, formed by a periodic array of fluid layers with alternating linear ...

Uniform circular array processing has been shown to be a very useful tool for broadband acoustic source localization over 360 degrees. Specifically, beamforming methods based on circular harmonics have attracted a lot of ...

From the analysis of sounds, the 7 notes composing a major key and its corresponding major scale are obtained in a reasoned way. These concepts represent one of the basic principles in Western music. This way, it is explained ...
