Um Mecanismo de Controle de Admissão Baseado no Grau de Ocupação para Redes Ópticas

This article presents the Load-Level-Based Admission Control mechanism (LLAC) proposed to provide quality of service for optical burst-switched networks. The LLAC mechanism admits bursts of a given service class according to the network load and a class-associated parameter. Based on this parameter, called load level, the proposed mechanism differentiates the burst blocking probability experien...

Aprendizaje incremental basado en población como buena alternativa al uso de algoritmos genéticos

At present, new computational models that attempt to overcome to the classical optimization models have emerged, this is the case of Evolutionary Computation, which has been popularized by Genetic Algorithms and their different variants that promise to be better. In this article we will discuss the benefits and/or shortcomings of basic Genetic Algorithm and Population-Based Incremental Learning...

Aplicação de redes neurais no controle de teores de cobre e ouro do depósito de Chapada (GO)

This study deals with application of artificial neural networks (ANNs) on grade control at mine sites inputting both geological and geotechnical variables. Case study is Chapada copper-gold deposit (Goiás, Brazil), located in the neoproterozoic Chapada-Mara Rosa volcano-sedimentary sequence. Ore is closely related to hydrothermal alteration, structurally controlled. The geological and geotechni...

Comunidades Virtuales Como Alternativa Para Facilitar el Intercambio de Conocimiento en Organizaciones

The virtual communities are settings for knowledge exchange, especially tacit knowledge. In large organizations, with branch offices or geographically dispersed functional units, knowledge exchange is generally restricted by the lack of convergence of people in the same physical space or schedule. In this investigation we have examined the behavior of the members of two virtual communities insi...
