Comportamiento del IPC de la BMV durante 2000-2009: Un enfoque de valores extremos

Estudio del comportamiento de la máquina asíncrona utilizando MATLAB©/Simulink

—The introduction of personal computers in engineering education allows using new complementary methods to reinforce theory and laboratory practices. In this paper, a complete software application is developed to study the behavior of the electric asynchronous machine using MATLAB®/Simulink. This tool allows complementing theoretical concepts, learning laboratory procedures and using software t...

Un enfoque gramatical para la extracción de términos índice

The extraction of the keywords that characterize a document in a given collection is one of the most important components of an Information Retrieval system. In this article, we propose to apply shallow parsing, implemented by means of cascades of finite-state transducers, to extract complex index terms based on an approximated grammar of Spanish. The coverage of the grammar is small but it all...

Un enfoque de control de movimiento de un helicóptero con cuatro rotores

In this paper a control scheme is described for regulation and trajectory tracking tasks planned for the motion of a helicopter with four rotors wich is also known as Quadrotor. The control scheme consists of four classical controllers and a generation stage of trajectories for the desired translational movement in the X − Y plane. Simulations results show the acceptable performance of the cont...

Descubriendo la Arquitectura de Sistemas de Software Híbridos: Un Enfoque Basado en Modelos i*

La mayoría de sistemas de software modernos se construyen integrando componentes de diversa naturaleza (comerciales, código libre, componentes legados, etc.), formando arquitecturas híbridas. La construcción de este tipo de sistemas se caracteriza por la adquisición de diversos componentes a proveedores externos a la organización que se integran con algún software hecho a medida. La correcta ap...
