Stabilizing controller design for uncertain nonlinear systems using fuzzy models
(Institute of Electrical and Electronics Engineers (IEEE), 1999-04-01)
A Lyapunov-based stabilizing control design method for uncertain nonlinear dynamical systems using fuzzy models is proposed. The controller is constructed using a design model of the dynamical process to be controlled. The ...
Viscosity, pH, and moisture effect in the porosity of poly(furfuryl alcohol)
(2013-01-01)
The poly(furfuryl alcohol) is highly indicated to obtain advanced carbonaceous materials due mainly to its good carbon yield (around 50%) and a controllable cure reaction. In the processing of some carbonaceous materials, ...
Amphibian secretions for drug discovery studies: A search for new antiparasitic and antifungal compounds
(2007-01-10)
The antiparasitic and antifungal activities of nine amphibian skin secretions were studied in different in vitro models. Seven secretions presented a considerable antiprotozoan activity and one showed promising results ...
Tempo de implantação de sistemas ERP: análise da influência de fatores e aplicação de técnicas de gerenciamento de projetos
(Universidade Federal de São Carlos (UFSCar), 2004-04-01)
Freqüentemente, a implantação de sistemas ERP é complexa e demorada, requerendo, em alguns casos, três ou quatro anos. em geral, um sistema ERP divide-se em módulos cujas implantações são feitas em vários estágios. Um ...
Simulation Tools for Power Electronics Courses Based on Java Technologies
(Institute of Electrical and Electronics Engineers (IEEE), 2010-11-01)
This paper presents interactive power electronics educational tools. These interactive tools make use of the benefits of Java language to provide a dynamic and interactive approach to simulating steady-state ideal rectifiers ...
Poly-lactide-co-glycolide microparticle sizes: A rational factorial design and surface response analysis
(Amer Scientific Publishers, 2006-08-01)
Microsphere size is a primary determinant of solute release velocity. We present here a rational way for producing PLGA microspheres with different and controlled sizes. the following process variables were studied: Stirring ...
A redistricting problem applied to meter reading in power distribution networks
(2014-01-01)
The capacitated redistricting problem (CRP) has the objective to redefine, under a given criterion, an initial set of districts of an urban area represented by a geographic network. Each node in the network has different ...
