1. Existência e homogeneização para um problema elíptico com fronteira livre não estacionária / Existence and homogenization for an elliptic problem with nonstationary free boundary
In this dissertation we study an elliptic problem in a bounded Lipschitz domain. Part of the boundary is moving and oscillates rapidly in the variable representing the space. Thus, we have a multi-scale free boundary problem. This problem has applications, for instance, in the construction of semiconductor films taking into account that the surface of the fi

2. Modelagem da Microestrutura de Tecidos Cardíacos
A few decades ago the cardiac tissue was believed to be an uniformly connected continumm. Currently, it is known that the cardiac cells are connected to each other via special protein channels called gap junctions, through which the ionic current flows between neighboring cells. The cardiac cells are arranged in distinct layers of muscle fibers surrounded by

3. Método de Elementos Finitos Enriquecidos para uma Classe de Problemas Elípticos Não Lineares com Coeficientes Altamente Oscilatórios
Fenômenos em materiais heterogêneos conduzem ao estudo de problemas em equações diferenciais parciais com coeficientes altamente oscilatórios. O tratamento numérico mediante o uso dos métodos tradicionais exige um alto custo computacional ou é inviável. No presente trabalho pretendemos estender o método residual free bubbles com o intuito de gerar

4. Metodo da homogeneização aplicado a otimização estrutural topologica / Homogenization method applied to structural topology optimization
This work aims to investigate and implement a structural topology optimization method based on microstructures. Two microstructure models are introduced in the optimal design problem: one orthotropic with holes, by homogenization, and other isotropic with penalization, by artificial constitutive equation. An implemented iterative program, based on the homoge
