Reconfiguration of distribution systems by a modified genetic algorithm
(2007-12-01)
In this paper a genetic algorithm based reconfiguration method is proposed to minimize the real power losses of distribution systems. The main innovation of this research work is that new types of crossover and mutation ...
String-averaging expectation-maximization for maximum likelihood estimation in emission tomography
(Iop Publishing Ltd, 2014-05-01)
We study the maximum likelihood model in emission tomography and propose a new family of algorithms for its solution, called string-averaging expectation maximization (SAEM). In the string-averaging algorithmic regime, the ...
Another prefiltering algorithm for adaptive IIR filtering
(1995-12-01)
An algorithm for adaptive IIR filtering that uses prefiltering structure in direct form is presented. This structure has an estimation error that is a linear function of the coefficients. This property greatly simplifies ...
Agrupamento de sequências de miRNA utilizando aprendizado não-supervisionado baseado em grafos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2016-08-12)
Cluster analysis is the organization of a collection of patterns into clusters based on similarity
which is determined by using properties of data. Clustering techniques can be useful in a
variety of knowledge domains ...

Análise e comparação entre algoritmos de percolação
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Matemática Aplicada e EstatísticaProbabilidade e Estatística; Modelagem Matemática, 2008-07-25)
In this work, we study and compare two percolation algorithms, one of then elaborated by Elias, and the other one by Newman and Ziff, using theorical tools of algorithms complexity and another algorithm that makes an ...
Um estudo algorítmico para a otimização de compra em grupo com múltiplos fornecedores e descontos em escala
(Universidade Federal do Rio Grande do NorteBrasilUFRNCiência da Computação, 2016-06)
This work studies the optimization in the distribution of buyers in a group of suppliers, taking into consideration the necessities and preferences based on the product’s characteristics, group discounts available by the ...

Using GPU to exploit parallelism on cryptography
(2011-09-12)
In this article we explore the NVIDIA graphical processing units (GPU) computational power in cryptography using CUDA (Compute Unified Device Architecture) technology. CUDA makes the general purpose computing easy using ...
