Modelo Conceptual de un Entrenador para Neuroendoscopía - Reporte Técnico

Abstract: The aim of this article is to present the concept design of a neuroendoscopic trainer which establishes a functional didactic relationship very close to the conditions presented in the operation room, in the operating field, in the spatial distribution and placement of the ports, besides the handling of a functional optic that allows perspective changes in solo-training. These characteristics are necessary to establish better learning protocols and to build the surgical curriculum outside of the operation room. The designed model is a first approximation of a training model that meets the needs of handle the optics of zero and different of zero degree, neurosailing and the management of real instrumental.

Dynamic Equivalent Based on Balanced Realizations for Interconnection of Photovoltaic Distributed System

Abstract: This paper presents a hybrid methodology to analyze electromagnetic transients in a photovoltaic distributed system. The methodology consists in split the system into two parts: the external zone, where the system is reduced by a dynamic equivalent obtained by the application of Balance Realization (BR) theory and the internal zone, where the system is modeled in detail and solved by a time domain technique. The methodology, that uses a predictor-corrector method to join both zones, does not need a transmission line to interconnect the systems but an element with reactive behavior to deal with the time coupling. In the first zone, the use of BR permits to obtain a new and reduced state-space description of the system that keeps the domain dynamics of the full system. The size of this system can be reduced as much as desired. Nevertheless, the resulting size is proportional to the accuracy. The BR decreases significantly the computational cost to simulate distributed networks. No restrictions are done in the internal zone where all the dynamics elements including the control if desired, can be simulated. The internal zone commonly contains non-linear or power electronic elements.

Diseño y evaluación de un sistema de iluminación de estado sólido de 28W con alto factor de potencia.

Abstract: En el presente trabajo se presenta el diseno de una fuente de alimentacion para un sistema de iluminacion de estado solido de veintiocho watts utilizando dos etapas en cascada (correccion de factor de potencia y fuente de corriente constante). Las principales caracteristicas de la fuente de alimentacion realizada son: alto factor de potencia, bajo contenido armonico, aislamiento galvanico y control de corriente constante independiente. Se desarrollo la metodologia de diseno correspondiente, se evaluo el desempeno electrico y ademas se presentan los parametros de interes obtenidos para la evaluacion de la solucion propuesta, los cuales son: factor de potencia, distorsion armonica total de corriente, eficiencia electrica, regulacion de tension y regulacion de corriente.

Diseño óptimo de un disipador de calor para luminaria LED mediante moderación modelación computacional - Optimal thermal design of a LED heat sink through computational modelling

Abstract: En el presente trabajo se desarrolla una seleccion de materiales y simulacion termica en el diseno de disipadores de calor para sistemas de iluminacion de estado solido (SSL) mejor conocidos como luminarias LEDs. Se desarrollo un modelo matematico con la capacidad de predecir el comportamiento termico de la luminaria cuando se encuentra en operacion. El modelo matematico fue resuelto mediante un software de distribucion libre el cual permite resolver ecuaciones diferenciales mediante el metodo de elemento finito. Los resultados obtenidos en el modelo matematico planteado fueron validados con los resultados obtenidos mediante experimentacion usando imagenes termograficas. Abstract: This work focuses on optimal materials selection and thermal simulation for the design of heat sinks for LED luminaires, a mathematical model was developed to predict temperature distributions in operating LED lamps. A test case was solved using a noncommercial finite element code and model results were validated against experimental measurements using a thermal imager showing that they are in close agreement with each other. Keywords: LEDs, aided computer design, computational modelling, material selection.
