1. An enriched meshless finite volume method for the modeling of material discontinuity problems in 2D elasticity
Abstract A 2D formulation for incorporating material discontinuities into the meshless finite volume method is proposed. In the proposed formulation, the moving least squares approximation space is enriched by local continuous functions that contain discontinuity in the first derivative at the location of the material interfaces. The formulation utilizes sp

2. Generalized linear differential equations in a Banach space: continuous dependence on parameters and applications / Equações diferenciais generalizadas lineares em espaços de Banach: dependência contínua com relação a parâmetros e aplicações
The purpose of this work is to investigate continuous dependence on parameters for generalized linear differential equations in a Banach space- valued setting. More precisely, we establish a theorem inspired by the clas- sical continuous dependence result due to Z. Opial. In addition, our second outcome extends, to Banach spaces, the result proved by M.

3. Applications of the combined continuous finite element and discontinuous Garlekin methods / Aplicações dos metodos de elementos finitos continuo e Garlekin descontinuo combinados
The present work is dedicated to study the continuous Finite Element Method (FEM) and the Discontinuous Galerkin Method (DGM) combined in the same simulation. In this work the DGM is dealt with as a variant of the Finite Element Method where the interpolation space is formed by discontinuous functions between elements. In this work, we propose a formulation

4. The Daugavet equation for operators on the space C(S) / A equação de Daugavet para operadores no espaço C(S)
Um operador linear limitado T entre espaços normados satisfaz a equação de Daugavet se II I + T II = 1+ T .Este trabalho tem como objetivo principal estudar tal equação para operadores lineares limitados no espaço das funções contínuas C(S), onde S é um espaço Hausdorff compacto. Para tanto, estudamos algumas representações de C*(S), o dual topo

6. Construções genéricas de espaços de Asplund C(K) / Generic constructions of Asplund spaces C(K)
In this work we consider a method of generic constructions of compact scattered non-metrizable spaces developed by Baumgartner, Shelah, Rabus, Juhasz and Soukup. We introduce new techniques and obtain new applications both relevant to topology of compact spaces and the geometry of Banach spaces of continuous functions. The new techniques concern new amalgama

7. Contribuições na teoria de otimização para alguns problemas de programação infinita e de programação com tempo continuo / Contributions in the optimization theory for some infinite programming problems and continuous time programming problems
In this thesis work it is regarded two type of abstract optimization problems. The _rst one corresponds to the in_nite programming problem. A such problem consists in minimizing a functional subject to an in_nite number of constraints, where the functions involved are dened in a Banach space. The second one is the continuous time programming problem, which c

8. A GPU-based architeture for supporting 3D interactions / Uma arquitetura de suporte a interações 3D integrada a GPU
Based on the hypothesis that the precise control of the motion of a cursor constitutes one of the elementary techniques for 3D direct manipulation tools, this thesis proposes an architecture for supporting a configurable control of the motion of cursors with respect to models deformed on graphics hardware. Integrated with the actual programmable rendering pi

10. Set-valued functions / Funções ponto a conjunto
We study a mapping called a set-valued map which associates with each point of a metric space a non empty subset of another metric space. In the case of single-valued maps, contin-uous functions are characterized by two equivalent properties: one in terms of neighborhood and other in terms of sequences. These two properties can be adapted to the case of set-

11. ANÁLISE DE VIBRAÇÕES DE SISTEMAS LINEARES E NÃO-LINEARES NO CONTEXTO DA FORMULAÇÃO FRACA, ANÁLISE MODAL E DECOMPOSIÇÃO DE KARHUNEN-LOÈVE / VIBRATION ANALYSIS OF LINEAR AND NON-LINEAR SYSTEMS IN THE CONTEXT OF WEAK-FORMULATION, MODAL ANALYSIS AND KARHUNEN-LOÈVEN BASIS
Vibration Analysis is treated in the context of weak formulation. A continuous system is formulated in the Hilbert space and one base is selected to project the dynamics. An approximation scheme is guaranteed by increasing the number of functions in the base used to represent the response. This is the idea behind methods like the Finite Element Method and As

12. Construção do espaço virtual na Internet : Como as pessoas se localizam em ambientes de chat
The objective of this work is to explain the construction of virtual space on the Internet, specifically in chat environments, from a psychology social-cultural approach. Following this approach, virtual space was understood as a relational space in continuous transformation, in which people locate each other in a computer environment. In this study, chats a
