Modelizacion, control e implementacion rel un procesador energetico torema para aplicacion en sistemas multisalida. Cualquier sistema electronico que incluya un procesado o tratamiento de la senal, y ademas, algun tipo de actuador mecanico generalmente necesita, como minimo, dos tensiones diferentes de alimentacion.

Excluyendo los sistemas de alimentacion distribuida, la solucion tecnica mas utilizada para proporcionar dos o mas tensiones consiste en las fuentes de alimentacion multisalida.

En una fuente de alimentacion multisalida los diferentes circuitos que conforman cada salida comparten un mismo transformador de potencia optimizando coste, masa, y volumen. Las ventajas obtenidas con este procedimiento tienen en su contra el efecto que sobre cada salida individual provocan las demas en su conjunto debido, principalmente, a los efectos de los elementos parasitos de los componentes. Un cambio de carga en una de las salidas produce un transitorio que es visto por todas las demas como un efecto de impedancia cruzada, y al final del transitorio, la tension de cada salida es diferente respecto a la que tenian antes del transitorio.

Este ultimo resultado se conoce como regulacion cruzada. La disminucion de los efectos de la regulacion cruzada ha sido objeto de estudio durante los ultimos anos.

El objetivo ha sido el desarrollo de distintas estrategias que permiten, desde disminuir los efectos de la regulacion cruzada hasta los niveles deseables, a eliminarla completamente. El resultado final suele suponer una penalizacion sobre el diseno del sistema directamente proporcional al grado de regulacion a conseguir en las distintas salidas. Entre las soluciones propuestas para eliminar la regulacion cruzada las tecnicas de post-regulacion se han consolidado como la opcion mas aceptada ya que, pueden aplicarse a cualquier convertidor y no suponen ninguna complejidad adicional a la hora de plantear el diseno.

En esta Tesis Doctoral se abordara el estudio de la tecnica conocida como postregulacion mediante transformador controlado, que si bien se ha empleado en convertidores resonantes, su.

El Sistema ‘s Open Secrets. In this article, the author talks about Venezuela’s national youth orchestra program called El Sistema whose attributes offer a direct challenge to traditional Western music practices. Thoughts on Seeing “El Sistema “.

This paper reports on a knowledge exchange project, funded by the Scottish Funding Council and undertaken by a group of researchers from three higher education institutions in Scotland and the project partner, Sistema Scotland.

This newly established charity is attempting to implement a major programme of social change, developed in Venezuela,…. The water vapor content of the atmosphere is the biggest restriction to the Millimeter and Sub-millimeter Astronomy. It also plays a crucial role in most of the atmospheric aplicciones. Nowadays water vapor is one of the less characterized meteorological parameter. It is a highly variable atmospheric constituent and its presence is a limiting factor to the obtention of high angular resolutions in interferometric observations of astrophysical interest.

Thus, the improved determination of the percentage of precipitable water vapor PWV is widely appreciated when performing a site testing for Millimeter Astronomy MA. Using its typical frequency the WVR monitors at 22 Ghz. A RS is a nothing but a set of sensors and radio transmitters carried out by a balloon up to They register twice a day at 0 UTC and 12 UTC the values of temperature, humidity and atmospheric pressure as a function of the altitude.

All the observations are immediately transmitted to a ground station. At the beginning of the ’90s GPS started to be used as an approach to the remote sensing of atmospheric water vapor Bevis et al, Geophys. The radio signal GPS is delayed by the atmosphere as it propagate from the satellites to the ground-receivers.

The tropospheric delay is modeled as the add of two contributions: Each of them is calculated as the product of a zenith path delay by a mapping function depending on the elevation angle. An estimate of the zenith wet delay can be transformed into an estimate of the PWV Bevis et al, ; Hogg et al. The procedure followed here is having comparable precision and accuracy with respect to the classical techniques Coster et al. El Sistema and American Music Education. The brainchild of Jose Antonio Abreu, El Sistemaa music education program for aspiring orchestra musicians launched in Venezuela for students of limited means and now spreading to other parts of the world, has become a subject of interest to music teachers and teacher educators in North America.

This article examines a bit of the program’s…. Nuevos sistemas aplicacilnes frecuencia intermedia para el IAR. Esto trae a la teoria del campo ligante el concepto de grupos funcionales.

El problema de estabilidad de los sistemas Hamiltonianos multidimensionales. El Sistema Fundamentals in Practice: El Sistema is a Venezuelan program of social change that has inspired a worldwide movement in music education.

El Sistema inspires social transformation and musical excellence to occur simultaneously and symbiotically. What does El Sistema look like within the context of a public school partnership in the United States? Los generadores de calentamiento por induccion son puentes inversores con carga resonante, cuya mision es basicamente crear una corriente sinusoidal de gran amplitud sobre la “bobina de caldeo”, que forma parte del tanque resonante.

En el interior de esta bobina se introduce la pieza que se desea calentar. EI campo magnetico creado induce corrientes superficiales corrientes de Foucault sobre la pieza, que producen su calentamiento. Los tanques resonantes tambien llamados osciladores utilizados en la actualidad son el resonante serie y el resonante paralelo.

Aunque ya desde hace algun tiempo se vienen construyendo generadores de alta potencia basados en estos dos osciladores, el exito nunca ha. Tal y como se explica en la introduccion de esta memoria, los puentes inversores utilizados deben operar drl una carga inductiva corriente toorricelli para evitar el fenomeno de la recuperacion inversa de sus diodos y la consiguiente ruptura de los transistores.

De la restriccion topologica anterior se deduce que el generador paralelo debe conmutar a frecuencias inferiores a la resonancia, y el serie a frecuencias superiores. A esta restriccion topologica hay que unir otra que es exclusiva del calentamiento por induccion: La corriente por la bobina de caldeo debe ser sinusoidal.

De no ser asi, resultaria imposible disponer toda torrricelli potencia de calentamiento sobre la pieza en el espesor requerido por la aplicacion. La conjuncion de las dos restricciones anteriores obligan al inversor paralelo a funcionar a la frecuencia de resonancia del oscilador. Esto imposibilita un control por variacion de frecuencia, regulandose la potencia desde la.

The Story of Carora: The Origins of El Sistema. Nanoparticulas basadas en complejos de Fe II con transicion de espin: Esta tesis doctoral esta organizada en 5 capitulos y esta destinada al estudio de sistemas de Fe II que presentan el fenomeno de la transicion de espin a escala nanometrica. Dd capitulo 1 contiene una introduccion general sobre materiales moleculares multifuncionales, destacando aquellos ejemplos mas importantes.
