1. O empreendedorismo de base tecnológica no complexo público de pesquisa em Minas Gerais: um olhar pelo calidoscópio da Teoria Ator-Rede
This thesis aimed at understanding how and under which circumstances researchers and the Public Institutions of Science and Technology (PIST) in the state of Minas Gerais interact to develop a technology-based entrepreneurship (TBE) that takes place at the Public Complex of Scientific Research (PCSR). Thus, this work sought to describe the actions that lead

2. Video segmentation based on motion coherence of particles in a video sequence
This work describes an approach for object-oriented video segmentation based on motion coherence. Using a tracking process based on adaptively sampled points (namely, particles), 2-D motion patterns are identified with an ensemble clustering approach. Particles are clustered to obtain a pixel-wise segmentation in space and time domains. The segmentation resu

3. SOCRATES : Sistema Orientado a objetos para CaRActerização de refaToraçõES / Object oriented system for characterization of refactorings
Refactoring is the activity of modifying a computer program s source code without changing its external behavior. In other words, it consists of changing a software system s structure without affecting its functionalities. The changes are done in order to let the code more understandable for humans that might work on it. In this sense, its goal is to lower m

4. CONTRIBUIÇÕES ÀS ABORDAGENS SA-DCT E DCT BASEADA EM BLOCOS PARA CODIFICAÇÃO DE IMAGENS ORIENTADA POR OBJETO / CONTRIBUTIONS TO THE SA-DCT AND BLOCK-BASED DCT APPROACHES FOR OBJECT-ORIENTED IMAGE CODING
Esta tese examina e apresenta contribuições para a codificação de textura intra-quadro na codificação de imagens baseada em objeto. Duas abordagens de codificação são focadas: a DCT baseada em blocos e a DCT adaptativa à forma (SA-DCT). São propostos indicadores morfológicos para extrair características de forma e textura intrínsecas ao objeto

5. MATHEMATICAL AND EXPERIMENTAL APPROACHES IN SHAPE-ADAPTATIVE VIDEO CODING / ABORDAGENS MATEMÁTICAS E EXPERIMENTAIS EM CODIFICAÇÃO DE VÍDEO ADAPTATIVA À FORMA
This thesis investigates shape adaptative coding of arbitrarily shaped segments. The texture and contour coding efficiency is discussed and solutions to tackle the associated problems are proposed. The presented methods are evaluated using standard image sequences. A mathematical approach for shape-adaptative transforms using linear operators is developed, f

6. Insoluble detergent-resistant aggregates form between pathological and nonpathological lengths of polyglutamine in mammalian cells
Pathological degeneration of neurons in Huntington’s disease and associated neurodegenerative disorders is directly correlated with the expansion of CAG repeats encoding polyglutamines of extended length. The physical properties of extended polyglutamines and the intracellular consequences of expression of polyglutamine expansion have been the object of in
