37. Desenvolvimento de procedimentos de modelagem de interação fluido-estrutura combinando a Teoria de Vigas de Cosserat e a metologia de fronteira imersa / Developing procedures for modeling fluid-structure interaction by combining the Cosserat beams theory and immersed boundary methodology
A presente tese descreve o trabalho de pesquisa realizado, com o objetivo de desenvolver, implementar e avaliar um procedimento de modelagem tridimensional de fenômenos fluidoestruturais que envolvem estruturas esbeltas, tais como vigas, barras e cabos. A nova abordagem adotada consiste na combinação da teoria de vigas de Cosserat aplicada a estruturas es

38. Redes de osciladores dissipativos : o modelo duplicado de Caldeira-Leggett, transferência quase-perfeita de estados e recoerência
In this work we treat firstly what we call the double Caldeira-Leggett model, which consists on the approach to the dynamics of two dissipative harmonic oscillators via Feynman-Vernon theory. We derived and solved the associated master equations in two different situations where i) each oscillator is coupled to its own reservoir and ii) both oscillators are

39. Espalhamento de ondas eletromagnéticas por esferas e cilindros magnéticos: confinamento e transporte de ondas no limite de pequenas partículas e independência da energia armazenada com relação à forma do centro espalhador / Electromagnetic wave scattering by magnetic spheres and cylinders: waves confinement and transport in the small particle limit and independence of the stored energy with respect to the shape of the scatterer
O espalhamento eletromagnético por uma esfera com propriedades ópticas e raio arbitrários, conhecido como espalhamento de Lorenz-Mie, ou por um cilindro circular infinito, pode ser resolvido analiticamente e é comumente tratado dentro da abordagem de espalhadores dielétricos. Na região óptica, tanto meio circundante quanto partícula espalhadora possu

40. Democracia e liberdade a legitimidade do governo, segundo Jean-Jacques Rousseau
Even though Rousseau had stated that democracy is a gods regime and that such form of government is surrounded by difficulties, mainly regarding its conservation, Rousseau notably is not an oppose of this model, but he recognizes and points out the most recurrent problems of the democratic government. Nevertheless, as he carries out the exceptional function

41. Condutância em Nanofios Magnéticos Diluídos / Conduct NCIA wires in Nano Magn à ticos Dilu Ados
Investigamos nanofios de semicondutores magnéticos diludos (DMSs - Diluted Magnetic Semiconductors) do tipo caroco-casca com dopagem remota tipo-n. A incorporação dos íons de Mn+2, que atuam como impurezas de spin 5/2 no caroço do fio, faz surgir um forte acoplamento de troca s-d entre os eletrons do fio e aqueles dos níveis d do íon Mn+2. Com a aplic

42. Sectorial innovation systems : an application of the concept in the brazialian and french fluid milk production chain
The aim of this study is to test a new framework in order to evaluate some fundamental institutional, technological and organizational factors in the innovation process carried out by food processing firms. We use case studies and the sectoral innovation system - SIS approach to give evidence about the innovation process carried out by fluid milk processors

43. Formas de interação e formas de visibilidade no site da PUC-SP: em busca dos valores da produção de conhecimento
The research proposed in this masters research lists itself as a descriptive and interpretative study of the ways the PUC-SP website brings visibility or not to its target audience the values of academic research which is one of the productions developed at the university. The problematic of this dissertation is how its present on the website and with what v

44. Essays in macroeconomy and dynamic term-structure models
This thesis is composed of three articles with the subjects of macroeconomics and - nance. Each article corresponds to a chapter and is done in paper format. In the rst article, which was done with Axel Simonsen, we model and estimate a small open economy for the Canadian economy in a two country General Equilibrium (DSGE) framework. We show that it is imp

45. Clima, cerebro y degeneración en Cabanis
This analysis of the arguments defended by Cabanis in Rapports du physique et du moral de l'homme takes as its point of departure his eighth and ninth Memoirs, which focus on analyzing the influences of regime and climate. These writings afford a new reading of the arguments Cabanis used to explain the relation between the physical traits and moral habits of

46. Numerical investigation of the three-dimensional secondary instabilities in the time-developing compressible mixing layer
Mixing layers are present in very different types of physical situations such as atmospheric flows, aerodynamics and combustion. It is, therefore, a well researched subject, but there are aspects that require further studies. Here the instability of two-and three-dimensional perturbations in the compressible mixing layer was investigated by numerical simulat

47. Aspectos não perturbativos das teorias de Yang-Mills no calibre abeliano maximal / Non-perturbative aspects of the Yang-Mills theories in the maximal Albelian gauge
In this, we study the nonperturbative effects associated to the presence of the horizon and to the condensation of local dimension two operators in an Eucledean SU(2)Yang-Mills theory quantized in the maximal Abelian gauge. Such effects are introduced in a way to preserve the properties of renormalizability and locality of the theory. The comparison with the

48. Anistia Política no Brasil : os indícios a as deturpações do discurso do esquecimento à luz da Teoria Discursiva do Direito e da Democracia
This work aims to demonstrate that there is a discourse of forget bound to the institution of amnesty, following the analysis of procedures involved with in legislative issues of amnesty in Brazil. The paradigm conceptions of Thomas Kuhn, concepts of Law Integrity of Ronald Dworkin, the Discursive Theory of Law and Democracy of Jurgen Habermas, and the Ident
