13. Boundary element method applied to the bending analysis of thin functionally graded plates
The present work introduces the boundary element method applied to the bending analysis of functionally graded plates. It is assumed that material properties are graded through the thickness direction of the plate according to a power law distribution. The neutral surface position for such plate is determined and the classical plate theory based on the exact

14. Thermomechanical buckling oftemperature-dependent FGM beams
Buckling of beams made of functionally graded materials (FGM) under thermomechanical loading is analyzed herein. Properties of the constituents are considered to be functions of temperature and thickness coordinate. The derivation of the equations is based on the Timoshenko beam theory, where the effect of shear is included. It is assumed that the mechanical

15. Distribuição do tempo de residência e letalidade no processamento térmico contínuo de líquidos com escoamento laminar não ideal em trocadores bitubulares. / Residence time distribution and lethality in the continuous thermal processing of liquids with non ideal laminar flow in bitubular exchangers.
Tubular heat exchangers are widely used for thermal processing of viscous liquid foods because they have larger hydraulic diameters than the plate heat exchangers. The calculation of lethality in this type of exchanger is directly related to velocity profile and the residence time distribution (RTD). For the laminar flow of viscous fluids, Newtonian and non-

16. Geração de eventos que seguem uma distribuição de lei de potência em ambientes geograficamente distribuídos / GENERATING EVENTS THAT FOLLOW A POWER LAW DISTRIBUTION IN GEOGRAPHICALLY DISTRIBUTED ENVIRONMENTS
Uma lei de potência define que a probabilidade de um evento r ocorrer, denotada por P(r), varia com o inverso de uma potência de r, ou seja, P(r) r -. Leis de potência estão presentes desde a biologia a ciências sociais, portanto o desenvolvimento de métodos e modelos para gerar eventos que seguem uma lei de potência tem sido assunto de investigação

17. O sistema constitucional assimétrico de saúde no Brasil : pradigmas para a construção de um modelo democrático / The asymetrical constitutional system of health in Brazil: paradigms for construction of a democratic model
This study aims to analyze the asymmetrical constitutional health care system in Brazil within a contemporary constitutionalism design, focused on social, political and legal aspects, as well as to propose new paradigms for the effective implementation of the Brazilian Unified Health Care System (SUS) institutional model. It also intends to identify the cons

18. Fundamentação cinética da estatística não gaussiana : efeitos em politrópicas
Considerando um gás ideal não relativístico, os fundamentos da teoria cinética padrão são investigados no contexto da mecânica estatística não-gaussiana introduzida por Kaniadakis. O novo formalismo é baseado na generalização do teorema-H de Boltzmann e na dedução de Maxwell da distribuição estatística. A distribuição lei de potência calc

19. Turbulência em cosmologia: análise de dados simulados e observacionais usando computação de alto desempenho / Turbulence in cosmology: analysis of simulated and observational data using high performance computing
Recent results from the study of the Large-Scale Structure evolution suggest that the process of structure formation may have similarities with the dynamics of a turbulent fluid. The scaling law for the energy distribution in a turbulent fluid shows an inertial range of power -5/3, known as the Kolmogorov s law. This thesis presents an evaluation of the grav

20. Superdifusão de caminhadas markovianas e não-markovianas. / Superdifusion of marcovian na non-marcovian walk.
Random walks are tools used in statistical physics to quantitatively describe the evolution of dynamical systems. Such systems are ubiquitous in Nature and each system requires a unique approach. Models of the motion of biological organisms are constructed based on the randomness observed in search strategies. Markovian models attempt to faithfully reproduce

21. A exigência do imposto sobre a doação de bens e direitos (ITCD) no caso do doador ser residente ou domiciliado no exterior
This dissertation aims to demonstrate the constitutionality of States and Federal District to create a tax on the donation of property and other rights Gift Tax - where the donor is resident or domiciled abroad. Federal Entities have approved this type legislation despite the absence of complementary national law as required in Articles 146 and 155, 1, III o

22. NavegaÃÃo em redes espacialmente correlacionadas. / Navigation in a spatially correlated network
A significant number of real networks have well-defined spatial characteristics. We studied how network with spatially correlated topolgies can influence the processes of navigation through them. For this, we study the behavior of the average shortest-path length to networks defined within Kleinbergâs model [1, 2] to analyze the navigation dictated by rules

23. Generating more realistic complex networks from power-law distribution of fitness
In this work we analyze the implications of using a power law distribution of vertice's quality in the growth dynamics of a network studied by Bianconi and Barabási. Using this suggested distribution we show the degree distribution interpolates the Barabási et al. model and Bianconi et al. model. This modified model (with power law distribution) can help u

24. Avaliação de processo de revisão tarifaria pedriodica das concessionarias de distribuição de energia eletrica no Brasil / Evaluation of the periodic tariff revision process for the brazilian electric power distribution utilities
The thesis originates in the evaluations of the economical regulation of the electric power sector in Brazil, particularly in what concerns the periodic tariff revision process implemented by the ANEEL, through the "tariff repositioning" methodology. This methodology ended up producing tariff injustices, with tariffs increases for the consumers of the econom
