Estimação de Probabilidade de Perda de Dados em Redes Através de Modelagem Multifractal de Tráfego e Teoria de Muitas Fontes

In this paper, we propose an approach to estimate the byte loss probability in computer network links considering multifractal properties of traffic flows. More specifically, we obtain a mathematical expression for the loss probability for finite buffer servers fed by multifractal traffic flows. The proposed approach is based on the Many Sources theory and on the multiplicative cascade based mu...

Comportamento de Estirpes de Bradyrhizobium japonicum em Diferentes Concentrações de Herbicidas

The Bradyrhizobium japonicun strains SEMIA 5073, SEMIA 5074, SEMIA 5079 and SEMIA 5080 were grown in vitro using Vincent medium combined with different rates of the herbicides imazaquin (0, 0.04, 0.12, 0.24, 0.36 μg a.i. g), clomazone (0, 0.4, 0.8, 1.6 and 3.2 μg a.i. g) and sulfentrazone (0, 0.2, 0.4, 0.8 and 1.6 μg a.i. g) to evaluate the strains tolerance to herbicides. The three herbicides ...

Identificação de Viabilidade de Leveduras Com Corante Vital Utilizando Histogramas de Palavras Visuais em Imagens Coloridas

This article presents a proposal to automate the classification of viability for yeast Saccharomyces cerevisiae species, responsible for the commercial production of ethanol, using as attribute the color absorbed by vital dye methylene blue. The methodology is used widely in the Brazilians distilleries and consist in count the colorless cells that are considered feasible, separate them from col...

Speech recognition in children with cochlear implants using two different speech processors Reconhecimento de fala em crianças usuárias de implante coclear utilizando dois diferentes processadores de fala

Purpose: To study comparatively the speech recognition skills in quiet and noise background situation in children with cochlear implants using two different speech processors. Methods: It was evaluated 26 children with cochlear implant device Nucleus 24M or 24K, Cochlear Corporation, divided in two groups according to the speech processor used. The Group 1 consisted of 16 children who used the ...
