Sliding mode control strategy for variable speed wind turbines
(IEEE, 2009)
The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, a robust control for variable speed wind power generation that incorporates a doubly feed ...
Object oriented simulation of hybrid renewable energy systems focused on supervisor control
(IEEE, 2009)
With eyes focused on simulation the authors review some of the main topics of Hybrid Renewable Energy Systems (HRES). Then they describe an Object Oriented model of a simple example of one of such systems, a micro-grid, ...
Sueño y humor en Aristófanes
(Adolph M. Hakkert, 2009)
Greek comedy uses different comic resources, and dreams are a good way of provoking laughter, as they provide an ideal means of distorting reality and parodying tragic events of similar kind. In the oniric scenes, Aristophanes ...
An agent-based multi-scale wind generation model
(ACTA Press, 2009)
This paper presents an agent-based model for simulating wind power systems on multiple time scales. The aim is to generate a flexible model that allows us to simulate the output of a wind farm. The model is developed using ...
Complete agent based simulation of mini-grids
(ACTA Press, 2009)
With eyes focused on simulation we review some of the main topics of Hybrid Renewable Energy Systems (HRES). Then we describe an Agent Based model of a simple example of one of such systems, a micro-grid, oriented to ...
Variable structure control for maximum wind power extraction
(ACTA Press, 2009)
The actual wind turbines are provided with adjustable speed generators.Iike the double feed induction generator, that are capable to work in variable speed operations. One of the main advantage of adjustable speed generators ...
Comunidades, científicos y especialistas en proyectos patrimoniales y museísticos: de “arriba-abajo” de “abajo-arriba”
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitateko Argitalpen Zerbitzua, 2009)
La observación sistemática aplicada a la evaluación de la gimnasia rítmica
(Gidekit ( Vitoria-Gasteiz), 2009)
[ES] El estudio pretende evaluar la actividad motriz de las gimnastas en el deporte de base con el objetivo de realizar un análisis detallado de las ocho dificultades corporales más utilizadas por las gimnastas y sus ...
La ambigua relación entre la biografía y la historia
(Universidad del País Vasco / Euskal Herriko Unibertsitatea, 2009)
Lo moderno de "Historia de una chica sola". El universo simbólico de Jordi Grau.
(Ediciones del Imán, 2009-12)
En 1969 el cineasta Jordi Grau rodó una película innovadora que se adhería a los postulados de la denominada "Escuela de Barcelona". El film, que pasó la censura vigente en la dictadura franquista, a pesar de tocar temas ...
