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...

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...
