25. Estrutura de dados Mate Face e aplicações em geração e movimento de malhas / The Mate Face data structure and applications in mesh generation and movement
Topological data Structures (DS) oer several advantages when performing a deformation on a mesh. These DSs allow movement throughout the mesh without modifying its topology, are relatively simple to implement, and there is always the possibility of merging it to simulation/deformation cycle on a completely automatic and ecient form. The main goal of this wor

26. Discursividades contemporaneas sobre politica : o discurso sobre a mutação da politica / Contemporary discourses on politics : the discourse of mutation of politics
This thesis deals with different angles brought to the theme of transformation of politics in the contemporary world, analyzing a relatively wide range of texts from media to theoretical discourse. The selected texts support a common opinion that politics is developing into something else and getting different meanings. Our analysis focus on discourse circul

27. Mecânica de suspensões magnéticas diluídas
This work concerns with an investigation of the dynamics of dilute suspensions composed by magnetic particles, considering microstructural and macroscopic aspects of this particulate systems. From the microstructure, it is known that magnetostatic attraction may lead to formation of aggregates in magnetic suspensions. In this way, numerical simulations have

28. ESTABLISHMENT OF ZONING GEOENVIRONMENTAL FOR URBAN PERIMETER OF SANTA MARIA- RS / ELABORAÇÃO DE ZONEAMENTO GEOAMBIENTAL PARA O PERÍMETRO URBANO DE SANTA MARIA - RS
Human activities, in their diversity, it impact on the environment, causing profound changes in the natural landscape, which may reflect a framework of environmental degradation and loss of quality of life, especially in urban environments. Therefore, the environmental analysis beyond the limits of understanding of the natural or human framework, but the int

29. MODELAGEM E SIMULAÇÃO DA DINÂMICA DE BÓIAS DE SUPERFÍCIE ANCORADAS / MODELING AND SIMULATION OF THE DYNAMIC OF SURFACE MOORED BUOYS
In this work a method for two-dimensional dynamic analysis of a cylindrical buoy under surfaced waves and moored to the seafloor by a flexible riser is presented. The finite element model used to describe the dynamics of the maritime line was developed by Lustosa (2002). This is a two node beam element based on the Euler-Bernoulli theory, with the element ki

30. A terra e a construção de uma poética da leveza / A terra e a construção de uma poética da leveza
This research approaches the relation between the lightness and weight, between materiality and immateriality, starting from the element earth. It is the creation of a set of productions starting from this dense, resistant substance that tends to weight, exploring its limits, searching for its lightness and immateriality. The present work unites reports of t

31. Avaliação de modelos fotoquímicos de qualidade do ar e estudo das circulações atmosféricas nos processos de dispersão de poluentes / Evaluation of air quality photochemical models and atmospheric circulations in the pollution dispersion processes.
Throughout numerical simulations and near to surface measurements of pollutants concentrations, in this work some meteorological situations of relevance for high ozone concentrations episodes over the Metropolitan Area of Sao Paulo (MASP) were studied., between 1999 and 2006. Firstly, two photochemical models, CIT and SPM-BRAMS, were evaluated in the sense o

32. Metodologia para processamento distribuído com aplicação em representação polinomial de superfícies / Distributed processing methodology with polynomial surface representation application
Pesquisas em diversas áreas do conhecimento estão envolvendo cada vez mais informações a serem processadas e demandam mais poder computacional para processar tais informações. Por esta razão, a área de Processamento Distribuído é uma área fundamental por possibilitar que grandes demandas de poder de processamento sejam supridas. Com base neste fat

33. Language and children s drawing : aspects of deaf children symbolic development and its therapeutic implications / Linguagem e desenho infantil : aspectos do desenvolvimento simbolico da criança surda e implicações terapeuticas
The interest for childrens drawing goes back to the last half of the Nineteenth Century and has been the object of several specialized studies because pictographic representation is considered a way for observing and understanding childrens development. The present work intends to approach drawing, as one of the ways of representing, naming and signifyin

34. Converting CSG models into meshed B-Rep models using euler operators and propagation based marching cubes
The purpose of this work is to define a new algorithm for converting a CSG representation into a B-Rep representation. Usually this conversion is done determining the union, intersection or difference from two B-Rep represented solids. Due to the lack of explicit representation of surface boundaries, CSG models must be converted into B-Rep solid models when

35. Automatic surface registration using spin-images / Registro automático de superfícies usando spin-image
This work describes a method based on three stages for reconstructing a model from a given set of scanned meshes obtained from 3D scanners. Meshes scanned from different scanners view points have their representation in local coordinate systems. Therefore, for final model reconstruction, an alignment of the meshes is required. The most popular algorithm for

36. UMA INVESTIGAÇÃO NA INTIMIDADE DO PORTRAIT FOTOGRÁFICO / UNE ENQUÊTE DANS L´INTIMITÉ DU PORTRAIT PHOTOGRAPHIQUE
Le but de cette thèse est le portrait photographique, examiné comme un genre de reproduction de l´image mais aussi comme un double processus interactif capable de réunir le portraituré, le photographe et le spectateur de la photo dans le moment qui précède et succède l´acte photographique. La réflexion développée ici s´intéresse à considérer
