1. The overcoming of the dichotomy heaven-earth: a study of the galilean critical for aristotelian cosmology and physics / A superaÃÃo da dicotomia cÃu-terra: um estudo da crÃtica galileana à fÃsica e à cosmologia aristotÃlicas
Nesta dissertaÃÃo, temos como objetivo realizar um estudo e reconstruÃÃo das crÃticas que Galileu empreende à fÃsica e à cosmologia de AristÃteles, tendo como Ãncora as obras Sidereus Nuncius e Primeira Jornada do DiÃlogo sobre os dois mÃximos sistemas do mundo. Os argumentos desenvolvidos pelo fÃsico pisano nestas obras, consolidam a teoria cop

2. Uma hipótese de Werner Heisenberg e o sentimento de solidão humana determinado pelo impacto das mudanças na explicação do cosmos. Um estudo a partir de representações sociais na literatura ocidental / One hypothesis of Werner Heisenberg and the human lonely by the impact of the changes in the explanation of the Cosmos. A study from social representation in the Ocidental Literature
Our Thesis aims to explain the implications of the Werner Heisenbergs hypothesis in literature, according to which this knowledge stands off from man in proportion to Cosmology progresses to mathematization and axiomatization and transforms the idea that he always had about the nature that surrounds him. Thus, it would exist in this man a true solitude feeli

3. Processos estocásticos em física: teoria e fundamentos
This work discusses some problems in physics using the language of stochastic processes. Firstly, we discuss the relationships between the formalisms of master equations, path integrals, and jumping processes. Each of them is a different prescription to define a Markovian process. Using these formalisms, we discuss the applicability of the classic Langevin m

4. Um estudo sobre a concepção de paradoxo segundo o pensamento de Augustus de Morgan
This work aims to analyze the concept of "paradox" posed in the work of The Budget Paradox (1872) of mathematical and logical English Augustus De Morgan (1806-1871). Here it is important to note that a large part of this book consists of re-prints of a series of writings by the author in journal Athenaeum, where its performance as auditor of literature. The

5. Effectiveness analysis of statics and dynamics hedge strategies for Brazilian arabian coffee market / Análise da efetividade das estratégias estáticas e dinâmicas de hedge para o mercado brasileiro de café arábica
This work was the purpose of analyzing the hedge strategies effectiveness, in terms of risks reduction to the arabian coffee market, with the futures markets use. It was observed, a priori, that arabian coffee is among the most risky products of the Brazilian agribusiness. Moreover, it was detected low use of futures mechanism not only for this product, but

6. Um ambiente de animacao dinamica de corpos rigidos
The general purpose of this work is the study of the fundamentals of the computer animation and the object-oriented development of a procedural animation system for visualization and dynamic simulations of 3D scenes in science and engineering applications. In such system an animation is specified by an animation language AL and an animation API.AL was derive

7. Comics are imagetic information attached to universitary teaching / As histórias em quadrinhos como informação imagética integrada ao ensino universitário
Comics are indispensable, expressive visual objects for communication and information because they have followed the cultural process of humanity since its beginning. Comics also exist because the technology made them possible. The scientificparadigm has changes from classic Cartesians to quantum, transforming the interaction between man and reality, from a

8. Analysis of reinforced concrete beams using strut and tie models / Análise de vigas de concreto armado utilizando modelos de bielas e tirantes
One of the main advantages presented by the strut-and-tie model is generality. This model is able to approximately represent, in a realistic and systematic way, the majority of todays reinforced concrete elements. Furthermore, it allows the physics-intuitive visualization of the behavior presented by structural concrete. On the other hand, its potentials a

9. Reflexões e contribuições para o ensino de gravitação clássica no nível médio
The subject of Classic Gravitation is part of the actual curriculum for High School in Brazil, and it is taught in the first year of that education level. This master thesis presents a research regarding the subject Classic Gravitation in High School. This research was based in two complementary guidelines of research and action. The first guideline was the

10. Duas Propostas de Ensino e suas Formas de Compreender a Eletricidade / Two High School Teaching Proposals and Their Ways to Understand Electricity
With this work we compared the ways to understand Electricity among high school students that had Electricity course with teaching proposals from GREF and Ramalho. Initially we searched for researches about students spontaneous concepts in electric current, electric resistance, energy and electricity intending to intending to arrange the existing models abou

11. A fast, high resolution, second-order central scheme for incompressible flows
A high resolution, second-order central difference method for incompressible flows is presented. The method is based on a recent second-order extension of the classic Lax–Friedrichs scheme introduced for hyperbolic conservation laws (Nessyahu H. & Tadmor E. (1990) J. Comp. Physics. 87, 408-463; Jiang G.-S. & Tadmor E. (1996) UCLA CAM Report 96-36, SIAM J.
