Fracture behaviour of poly[ethylene–(vinyl alcohol)]/organo-clay composites
(WileySociety of Chemical Industry, 2009)
BACKGROUND: Ethylene–(vinyl alcohol) (EVOH) copolymer/organo‐modified montmorillonite (OMMT) composites were investigated. Composites with two different percentages by weight of OMMT were prepared using a melt‐extrusion ...
A Triangulation Approach to Asymptotically Exact Conditions for Fuzzy Summations
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
Many Takagi-Sugeno (T-S) fuzzy control-synthesis problems in the literature are expressed as the problem of finding decision variables in a double convex sum (fuzzy summation) of positive definite matrices. Matricespsila ...
Sampled-data gain scheduling of continuous LTV plants
(Elsevier, 2009)
This paper discusses the design of gain-scheduled sampled-data controllers for continuous-time polytopic linear parameter-varying systems. The scheduling variables are assumed to be available only at the sampling instants, ...
Influence of femtolaser notch sharpening technique in the determination of essential work of fracture (EWF) parameters
(Elsevier, 2009-06)
The fracture behaviour of a 0.5 mm thick ethylene-propylene block copolymer is analyzed using the essential work of fracture method, using DENT-type specimens. The influence of three experimental parameters in the technique ...
Improved efficiency in sensitivity calculations for bioreactor models
(Elsevier, 2009)
Sensitivity functions are a basic tool in the parametric identification of models. They can be used to obtain the gradient needed by optimization algorithms in the estimation of parameters and to calculate the Fisher ...
The Essential Work of Fracture (EWF) method – Analyzing the Post-Yielding Fracture Mechanics of polymers
(Elsevier, 2009-12)
The Post-Yielding Fracture Mechanics describe the fracture behaviour of pre-cracked films and thin sheets that show yielding phenomenon at the crack tip during fracture. The Essential Work of Fracture method (EWF) has been ...
Polynomial Fuzzy Models for Nonlinear Control: A Taylor Series Approach
(Institute of Electrical and Electronics Engineers (IEEE), 2009-12)
Classical Takagi-Sugeno (T-S) fuzzy models are formed by convex combinations of linear consequent local models. Such fuzzy models can be obtained from nonlinear first-principle equations by the well-known sector-nonlinearity ...
Optimization of deposition voltage of cataphoretic automotive primers assessed by EIS and AC/DC/AC
(Elsevier, 2009)
The dependence of the anticorrosive properties of a cataphoretic paint with the applied deposition voltage was studied by the so-called EIS tests; an accelerated cyclic test used in the automotive industry; and a rapid ...
Reduciendo distancias entre el control borroso y el control no lineal: luces y sombras
(Comité Español de Automática, 2009)
Aunque el control borroso nació como una metodología heurística, las formulaciones en desigualdades matriciales lineales del control borroso se han convertido en la herramienta más utilizada en dicho área desde los años ...
Diseño prospectivo y elementos de uso en parques urbanos a partir de la experiencia de las personas mayores
(ResmaUniversidad de La Laguna, 2009)
Attention to the care and design of urban public spaces is a key
factor when considering the quality of urban life. Parks and
squares are spaces dedicated for everybody’s use and enjoyment,
although some people, depending ...
