Elsevier (2012)The main aim of this research work is to draw up a framework proposal for integrated materials and process selection in product design. Following an in-depth review of existing studies and the factors that influence ... -
Biotic degradation of poly(DL-lactide) based nanocomposites
Elsevier (2012)Amorphous PLA nanocomposites based on organic modified kaolinite (KAO) and montmorillonite (MONT) at 4 wt.% were prepared by melt blending and then biodegraded in compost. All materials showed effective degradation in ... -
Study of the thermal degradation of bioactive sol–gel coatings for the optimization of its curing process
Akadémiai Kiadó (2012-02)A set of materials has been prepared by sol–gel process containing different quantities of hydroxyapatite (0, 2.5 and 5% HAp w/w) using as silica precursors glycidyloxypropyltrimethoxysilane (GPTMS) and triethoxyvinyl ... -
Explicit Predictive Control with Non-Convex Polyhedral Constraints
Elsevier (2012-02)This paper proposes an explicit solution to the model predictive control of linear systems subject to non-convex polyhedral constraints. These constraints are modeled as the union of a finite number of convex polyhedra. ... -
Prensado, con métodos de la cerámica plana, de piezas cerámicas curvas con especificaciones geométricas de elevada precisión
Sociedad Española de Cerámica y Vidrio (2012-03)In order to obtain high-precision three-dimensional pieces by dry pressing, two approaches were studied: modelling the material flow and strain during pressing; and evaluating the bulk density (Da) distribution in a pressed ... -
Estimación del dominio de atracción de sistemas no lineales mediante modelos borrosos polinomiale
Elservier (2012-04)Many approaches in fuzzy systems literature express LMI con- ditions for a Takagi-Sugeno model and finish the problem once those conditions are feasible. However, studying the obtained re- gion of attraction and its ... -
Estimation in multisensor networked systems with scarce measurements and time varying delays
Elsevier (2012-04)In this paper, the problem of estimating signals from a dynamic system at regular periods from scarce, delayed and possibly time disordered measurements acquired through a network is addressed. A model based predictor that ... -
