Identificação de um sistema experimental caótico: circuito de Chua
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia ElétricaUTFPR, 2019-06-28)
This work presents concepts of nonlinear system identification and chaos through NARMAX representations and the Chua’s circuit forced with a DC voltage source in series with the Chua’s diode. In this context, were used ...
VAr planning using genetic algorithm and linear programming
(2001-05-01)
A combined methodology consisting of successive linear programming (SLP) and a simple genetic algorithm (SGA) solves the reactive planning problem. The problem is divided into operating and planning subproblems; the operating ...
Estudo de análises linear e não linear aplicado a flambagem
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2017-11-16)
Buckling can be considered a failure due to structural instability. Both design and engineering applications where slender elements are involved, buckling failure must be verified. In this context this research presents a ...
Second-order biases of maximum likelihood estimates in overdispersed generalized linear models
(2001)
In this paper, we derive general formulae for second-order biases of maximum likelihood estimates in overdispersed
generalized linear models, thus generalizing results by Cordeiro and McCullagh (J. Roy. Statist. Soc. Ser. ...
Análise de dados longitudinais para variáveis binárias
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2009-03-05)
The objective of this work is to present techniques of regression analysis for longitudinal data when the response variable is binary. Initially, there is a review of generalized linear models, marginal models, transition ...
A comparative study between two relaxed LMI-based fuzzy control designs
(2005-09-01)
A comparative study, with theoretical analysis and digital simulations, of two conditions based on LMI for the quadratic stability of nonlinear continuous-time dynamic systems, described by Takagi-Sugeno fuzzy models, are ...

A least cost transmission planning model considering operation cost
(2014-02-05)
Existing transmission planning models consider basic aspects of the problem. In practice, a transmissionutility needs to model other important details such as operation cost of the power system. In this article, a least ...
