Predictor-Corrector Primal-Dual Interior Point Method for Solving Economic Dispatch Problems: A Postoptimization Analysis
(Mathematical Problems in Engineering, 2012-01-01) [Artigo]
This paper proposes a predictor-corrector primal-dual interior point method which introduces line search procedures (IPLS) in both the predictor and corrector steps. The Fibonacci search technique is used in the predictor ...
A path- and label-cost propagation approach to speedup the training of the optimum-path forest classifier
(Pattern Recognition Letters, 2014-04-15) [Artigo]
In general, pattern recognition techniques require a high computational burden for learning the discriminating functions that are responsible to separate samples from distinct classes. As such, there are several studies ...
A novel algorithm for feature selection using Harmony Search and its application for non-technical losses detection
(Computers & Electrical Engineering, 2011-11-01) [Artigo]
Finding an optimal subset of features that maximizes classification accuracy is still an open problem. In this paper, we exploit the speed of the Harmony Search algorithm and the Optimum-Path Forest classifier in order to ...
Misturador para análise de propriedades reológicas
(Energia na agricultura, 2010) [Artigo]
This study aimed to evaluate the use of a mixer to determine the rheological properties of fluids. The mixer is comprised of an agitation tank and an anchor type impeller. The tests were performed with honey and fruit ...
Núcleo de estudos e práticas pedagógicas: um espaço para aprender e conhecer

Photo-induced electron trapping in indirect bandgap AlxGa1-xAs : Si at low temperature
(Journal of Physics: Condensed Matter, 1999-01-18) [Artigo]
A variation of photoconductivity excitation with wavelength is applied to Si-doped Al0.56Ga0.44As (indirect bandgap material) for a wide range of temperature. The lower the temperature the lower the photocurrent below 70 ...
Multiobjective 0-1 integer programming for the use of sugarcane residual biomass in energy cogeneration
(International Transactions in Operational Research, 2011-09-01) [Artigo]
It is well known that Brazil is the largest producer of sugarcane in the world. Nevertheless, a great concern exists about the crop system used, because the most common practice is manual harvesting with prior straw burning. ...
Effects of methylmercury on electric organ discharges in the weak electric fish Gymnotus sylvius
(Psychology and Neuroscience, 2013-07-05) [Artigo]
Methylmercury (MeHg) is present in the environment because of natural and anthropogenic causes. MeHg can reach the central nervous system (CNS) and cause neurological damage in humans and animals. Electric organ discharges ...
Optimizing feature selection through binary charged system search
(Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 2013-09-26) [Trabalho apresentado em evento]
Feature selection aims to find the most important information from a given set of features. As this task can be seen as an optimization problem, the combinatorial growth of the possible solutions may be inviable for a ...
What is the importance of selecting features for non-technical losses identification?
(Proceedings - IEEE International Symposium on Circuits and Systems, 2011-08-02) [Trabalho apresentado em evento]
Although non-technical losses automatic identification has been massively studied, the problem of selecting the most representative features in order to boost the identification accuracy has not attracted much attention ...
