1. Otimização de topologia de estruturas e componentes / Topology optimizatin of sctructures and components
A otimização de topologia (OT) é uma técnica de otimização que visa auxiliar o projetista na fase de concepção estrutural, buscando a melhor distribuição de uma quantidade fixa de material em um domínio estendido de projeto. Combina um método de análise estrutural com um algoritmo de programação matemática (PM). Neste trabalho, a análise est

2. Otimização de topologia de estruturas e componentes / Topology optimizatin of sctructures and components
Topology optimization (TO) is an optimization technique that aims to help the designer in the phase of structural conception, seeking a better distribution of one fixed amount of material in a extended design domain. It combines a method of structural analysis with a mathematical programming (MP) algorithm. In this work, structural analysis is done by Finite

3. Propriedades homologicas de grupos pro-p / Homological properties of pro-p groups
In this work, we prove two results about homological properties of metabelian pro-p groups. The first one answers positively a conjecture suggested by J. King that, if G is a finitely generated metabelian pro-p group and m a positive integer, G embeds in a metabelian pro-p group of homological type F P m. The second result caracterize the modules B of homolo

4. SU(3) model description of Be isotopes
Experimental data on light nuclei close to dripline suggests that as the nucleon number asymmetry increases, the shell structure from stability line is not preserved. In contrast with spherical shell model, Elliott's SU(3) model, uses a deformed multi-nucleon basis to describe nuclear states. The SU(3) symmetry is a strong feature of 1p shell nuclei, where s

5. Aplicação de métodos quimiométricos na especiação de Cr(VI) em solução aquosa
The equilibria, the spectra and the identities of the species of Cr(VI) that are present in aqueous solution have long been an active subject of discussion in the literature. In this paper, three different chemometric methodologies are applied to sets of UV/Visible spectra of aqueous Cr(VI) solutions, in order to solve a chemical system where there is no ava

6. Correspondence analysis applied to microarray data
Correspondence analysis is an explorative computational method for the study of associations between variables. Much like principal component analysis, it displays a low-dimensional projection of the data, e.g., into a plane. It does this, though, for two variables simultaneously, thus revealing associations between them. Here, we demonstrate the applicabili
