An observer-based vaccination control law for an SEIR epidemic model based on feedback linearization techniques for nonlinear systems
(Springer, 2012-09)
This paper presents a vaccination strategy for fighting against the propagation of epidemic diseases. The disease propagation is described by an SEIR (susceptible plus infected plus infectious plus removed populations) ...
Sliding Mode Control Strategy for Wind Turbine Power Maximization
(MDPI, 2012-07)
The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, a sliding mode control for variable speed wind turbine that incorporates a doubly fed ...
Black Holes, Cosmological Solutions, Future Singularities, and Their Thermodynamical Properties in Modified Gravity Theorie
(MDPI, 2012-09-18)
Along this review, we focus on the study of several properties of modified
gravity theories, in particular on black-hole solutions and its comparison with those solutions in General Relativity, and on Friedmann–Lemaˆıtr ...
The Oxidative State of Chylomicron Remnants Influences Their Modulation of Human Monocyte Activation
(Hindawi Publishing Corporation, 2012)
Chylomicron remnants (CMRs) contribute directly to human monocyte activation in vitro, by increasing reactive oxygen species (ROS) production and cell migration. In this study, the effects of the oxidative state of CMR on ...
Experiences of Public-Private Collaboration for Stimulating
(Eurojournals publishing, Inc., 2012-04)
For over a decade now, work has been ongoing on the professional organization and
management of town centre retail spaces in Spain under what is known as the Open
Shopping Centre model. Introducing this model has involved ...
Breed effect on quality veal production in mountain areas: Emphasis on meat
(Elsevier, 2012)
This study was designed to compare the quality of veal produced from ‘Tudanca x Charolais’ cross (n=6) and Limousin (n=6) breeds when allowed to feed freely on mountain pastures and suckle naturally from birth to 7 months ...
Dynamics of pneumococcal nasopharyngeal carriage in healthy children attending a day care center in northern Spain. Influence of detection techniques on the results
(BioMed Central, 2012-03-22)
Background: Pneumococcal nasopharyngeal carriage precedes invasive infection and is the source for dissemination of the disease. Differences in sampling methodology, isolation or identification techniques, as well as the ...
Fixed and Best Proximity Points of Cyclic Jointly Accretive and Contractive Self-Mappings
(Hindawi Publishing Corporation, 2012)
p(>= 2)-cyclic and contractive self-mappings on a set of subsets of a metric space which are simultaneously accretive on the whole metric space are investigated. The joint fulfilment of the p-cyclic contractiveness and ...
Stability of Switched Feedback Time-Varying Dynamic Systems Based on the Properties of the Gap Metric for Operators
(Hindawi Publishing Corporation, 2012)
The stabilization of dynamic switched control systems is focused on and based on an operator-based formulation. It is assumed that the controlled object and the controller are described by sequences of closed operator pairs ...
About the Stabilization of a Nonlinear Perturbed Difference Equation
(Hindawi Publishing Corporation, 2012)
This paper investigates the local asymptotic stabilization of a very general class of instable autonomous nonlinear difference equations which are subject to perturbed dynamics which can have a different order than that ...
