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 ...
Studying the degradation of polyhydroxybutyrate-co-valerate during processing with clay-based nanofillers
(Wiley, 2009)
Polyhydroxybutyrate-co-valerate (PHBV) is attracting interest as a new material for packaging applications and nanoparticulate layered silicates are being increasingly explored as a way to improve PHBV film properties. In ...
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 ...
A review of machining monitoring systems based on artificial intelligence process models
(Springer-Verlag, 2009)
Many machining monitoring systems based on artificial intelligence (AI) process models have been successfully developed in the past for optimising, predicting or controlling machining processes. In general, these monitoring ...
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 ...
Reduction of low voltage power cables electromagnetic field emission in MV/LV substations
(Elsevier, 2008)
In this paper a solution to reduce magnetic field emission levels generated by MV/LV substation power cables is proposed. The reduction is obtained by the arrangement of the phases in a proper way and by shielding the ...
Characterization of the morphology and thermal properties of Zein Prolamine nanostructures obtained by electrospinning
(Elsevier, 2008)
Zein is a "yellowish" colored maize storage prolamine that shows great interest in a number of industrial applications such as food, food coating and food packaging. Nanofibers generated by electrospinning from solution ...
Control of a ceramic tiles cooling process based on water spraying
(Elsevier, 2009)
The control of the surface temperature of ceramic tiles in a real industrial production line is developed. The process consists of a transportation band that carries the hot tiles through a water sprayer whose objective ...
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 ...
