1. Caracterização e modelagem de redes biológicas geográficas / Characterization and modelling of biological networks
Nesta tese apresentamos uma metodologia de mapeamento capaz de gerar representações em termos de grafos para sistemas biológicos de conectividade complexa. Tais sistemas são inicialmente armazenados na forma de imagens digitais e em seguida submetidos a um pré-processamento com objetivo de padronizar as imagens. As imagens pré-processadas são então u

2. MagnetViz : design and evaluation of a physics-based interaction technique for graph visualization / MagnetViz : projeto e avaliação de uma técnica de interação baseada em física para visualização de grafos
Esta dissertação apresenta MagnetViz, uma técnica para visualização de grafos. Enquanto a maior parte das técnicas visualizam um layout de grafo estático pre-computado, MagnetViz permite que usuários dinamicamente alterem o layout de um grafo de forma a melhor satisfazer suas necessidades. Isso é feito ao construir em cima da metáfora de física de

3. FAULT MESHING GENERATION IN SEISMIC DATA BY COMPETITIVE LEARNING / GERAÇÃO DE MALHAS DE FALHAS EM DADOS SÍSMICOS POR APRENDIZADO COMPETITIVO
Manual fault mapping from 3D seismic data is a time-consuming task. A plethora of seismic attributes has been proposed to enhance the discontinuity measures associated with faults. However, faults viewed through these attributes appear more like trends than well-defined, continuous surfaces, posing obstacles to the automation of the fault modeling process. T

4. Modelos grafos para expressão gênica
The purpose of this work is to examine statistical methodologies that can be applied to problems that involve a large number of variables using as a tool graphical models that assist on the visualization of the conditional independency and dependency structure, thus a graphical model represents the relationship between random variables (dependence, independe

5. A constraint-based model to support electronic TV network design
Electronic Television Network Design is well established when electronic physics concepts and computer techniques joint trough mathematical equations and geometrics concepts, to represent real effects. Even though, the two fields have significant different concepts. This research has as objective to propose one approach constraint-based data model, to suppor

6. Elaborando e lendo gráficos cartesianos que expressam movimento: uma aula utilizando sensor e calculadora gráfica
The purpose of this research was to investigate and analyze the meaning production for 10th graders of a school from the state network in Minas Gerais, about cartesian graphs that represent the rectilinear movement. The aspects favored in the understanding and elaboration of the graph using pencils and paper, a sensor, the graphic calculator, the teachers pa

7. Uma ferramenta para a visualização de ESTs / A tool for visualizing ESTs
Expressed Sequence Tags (ESTs) são amostras de trechos de genes, que funcionam como moldes na síntese de proteínas. Como a quantidade de ESTs coletados nos últimos anos é muito grande, o uso de computadores tornou-se imprescindível para a identificação de genes, proteínas e para a descoberta de genes homólogos. Este trabalho propõe uma metodologia

8. Instrumentação inteligente via web services. / Intelligent instrumentation through web services.
In this work is presented the integration of an established system of intelligent instrumentation with the Web Service?s architecture, in accordance with the IEEE 1451.1 standard. It is suggested the association of a data-communication protocol with the concept of Transducer Electronic Data Sheet (TEDS) to a Web Service for making possible the remote configu

9. Computational methodology to evaluate the quality of power systems restoration plans / Metodologia computacional para avaliação da qualidade de planos de recomposição de sistemas de energia eletrica
A successful restoration depends on the quality of the restoration plans, that describe the sequence of control actions that must be executed to reenergize different areas (of the power system) just after total or partial blackouts. This work proposes a methodology to automatically evalute the quality of power system restoration plans, related to (a) the fle

12. PseudoViewer2: visualization of RNA pseudoknots of any type
Visualizing RNA pseudoknot structures is computationally more difficult than depicting RNA secondary structures, because a drawing of a pseudoknot structure is a graph (and possibly a nonplanar graph) with inner cycles within the pseudoknot, and possibly outer cycles formed between the pseudoknot and other structural elements. We previously developed PseudoV
