Adaptive variable structure control law for a variable speed wind turbine
(WSEAS, 2011)
The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, an adaptive robust control for a doubly feed induction generator drive for variable speed ...
High fat diet-induced non alcoholic fatty liver disease in rats is associated with hyperhomocysteinemia caused by down regulation of the transsulphuration pathway
(BioMed Central, 2011)
Background
Hyperhomocysteinemia (HHcy) causes increased oxidative stress and is an independent risk factor for cardiovascular disease. Oxidative stress is now believed to be a major contributory factor in the development ...
A new look at Marx's refutation of Ricardo's refutation of the labor theory of value
(2011)
In this paper, I would like to bring back to light the forgotten critique of Marx to the widely accepted view that Ricardo succeeded in refuting the universal validity of the labor theory of value in "Principles", chapter ...

(Innobasque, 2011)
This is the summary of the PhD of Dr Calzada on the comparative analysis of three city-regions: the Basque Country (Spain), Dublin (Ireland) and Portland (Oregon).
Dynamic comparison of different types of slab tracks and ballasted track using a flexible track model
(Sage Publications, 2011-11)
The dynamic performance of a ballasted track and three types of slab tracks is analysed and compared by means of a comprehensive dynamic model of the train-track system, generated using two commercial analysis software ...
Advances towards behaviour-based indoor robotic exploration
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2011-09-05)
The main contributions of this research work remain in object recognition by computer vision, by one side, and in robot localisation and mapping by the other. The first contribution area of the research address object ...

Measuring the Effect of the Real Estate Bubble: a House Price Index for Bilbao
(2011-11)
A spatio-temporal model is proposed aimed at producing an index of housing prices. A hedonic model with geographically varying coefficients is coupled with a non parametric estimation of the trend, whence a price index is derived.
Hardware and software architecture for overhead line rating monitoring
(IEEE, 2011-06)
Real time monitoring in both electrical transmission and distribution lines is an interesting option for knowing the electrical load level of these lines. The information about the load level allows alleviating the overloaded ...
Kalman Filtering in R
(Journal of Statistical Software, 2011-03)
Support in R for state space estimation via Kalman filtering was limited to one package, until fairly recently. In the last five years, the situation has changed with no less than four additional packages offering general ...
