25. Alocação dinâmica de tarefas periódicas em NoCs malha com redução do consumo de energia / Energy-aware dynamic allocation of periodic tasks on mesh NoCs
O objetivo deste trabalho é propor técnicas de alocação dinâmica de tarefas periódicas em MPSoCs homogêneos, com processadores interligados por uma rede emchip do tipo malha, visando redução do consumo de energia do sistema. O foco principal é a definição de uma heurística de alocação, não se considerando protocolos de escalonamento distribu�

26. Uma contribuiÃÃo ao estudo da sedimentaÃÃo gravitacional em batelada
Thickeners are equipments that uses the gravitational force as separating agent of suspended solid particle in liquid chains of industrial processes. The frequent use of the settlers in chemical industries is the reason of the interest on the development of studies on the subject. The batch sedimentation is the starting point for the project of continuous in

27. Large eddy simulation of three-dimensional turbulent flows by the finite element method
The main objectives of this work are the formulation, implementation and applications of a numerical algorithm to simulate turbulent, incompressible, isothermal flows. The transient three-dimensional flow is analyzed using an explicit Taylor-Galerkin scheme and the finite element method with hexahedrical eight-node element. Turbulence is simulated using Larg

28. ROBUST CONTROL LQG/LTR WITH RECOVERY OF THE PROFIT OF THE MESH OF TRANSFERENCE / CONTROLE ROBUSTO LQG/LTR COM RECUPERAÇÃO DO GANHO DA MALHA DE TRANSFERÊNCIA
In this work is presented a method to solve the Eigenstructure Allocation pro- blem for multivariable dynamic systems by means of Robust Controllers Design Linear Quadratic Gaussian, LQG/LTR Loop transfer Recovery and Hierarchical Genetic Algorithm in three levels. It shows an unied method for controllers ro- bust design that are one systematical of the thre

29. Theoretical-experimental analysis of shrinkage : study of driyng of bananas / Analise teorico-experimental do encolhimento : estudo da secagem de banana
The drying process may induce collateral effects in the dry material, such as the volume reduction. The objectives of this study are to investigate the characteristics of the shrinking process and to consider a strategy for inclusion of these effects in a drying simulation. Banana was chosen as a case study due to its importance in Brazil and to the existenc

30. THE STRUCTURAL BEHAVIOUR OF COMPOSITE LAMINATES MANUFACTURED USING RESIN INFUSION UNDER FLEXIBLE TOOLING
This thesis presents a detailed investigation on the structural behaviour of hybrid plain weave composite laminates manufactured using Resin Infusion under Flexible Tooling (RIFT) process under static and dynamic impact loading conditions. Composite laminates were manufactured using a newly developed RIFT manufacturing facility marking the beginning of a new

31. Esquemas de proteção e conversão de comprimento de onda em redes opticas WDM / Protection schemes and wavelength conversion in WDM optical networks
This work examines the blocking reduction with the use of wavelength converters and some protection schemes in optical networks. Sub-Graph Routing Protection, a protection method that creates different failure-dependent protection paths for each connection is presented. Some schemes were proposed and compared, aiming at eliminating unnecessary connection rea

32. VariaÃÃo espacial e temporal da comunidade microfitoplÃnctÃnica em ecossistemas costeiros localizados no litoral sul de Pernambuco, Nordeste do Brasil
The coastal marine environment shows a strong ocean- continent-atmosphere interaction and for that reason is considered extremely complex from the biological point of view due to the influence of many systems, so it can be characterized as one of the most fertile and dynamic of the hydrosphere. The estuarine complex (Ilhetas and Mamucaba rivers) and the Tama

33. Building 3D frameworks of accessory aquatic systems
We consider a mathematical framework for spatially describing accessory aquatic systems that belong to a major hydric complex like a large reservoir created by damming a river. The central purpose is to provide a precise and complete mathematical covering of short-scale or localized water bodies, with typical lengths between 1 to 10 km, that are laterally at

34. OTIMIZAÇÃO DE CASCAS SUBMETIDAS A CARREGAMENTO DINÂMICO / OPTIMIZACIÓN DE CASCAS SOMETIDAS A SOBRECARGA DINÁMICA / OPTIMIZATION OF SHELL STRUCTURES UNDER DYNAMIC LOADS
The main goal of this work is to present a methodology and a computer code which allow the designer, by means of optimization techniques, to obtain efficient shapes of plate and shell structures under linear-elastic behavior and dynamic loads. With this objective, it is used the optimization program SHELLD that includes the geometric modeling, the mesh gener

35. Interação dinamica de estruturas bidimensionais com o solo : uma comparação entre um metodo semi-analitico e o metodo dos elementos de contorno
In this work two methods to treat the dynamic soil-structure interaction phenomena are compared: a Superposi tion Method (SPM) and the Boundary Element Method (BEM) .Complete compliances matrices for the dynamic interaction of bidimensional surface and embedded foundation structures, interacting through the soil in frequency domain are obtained. A discussion

36. Unstable Angina Pectoris and the Progression to Acute Myocardial Infarction: Role of Platelets and Platelet-Derived Mediators
The conversion from stable to unstable angina and the further progression to myocardial infarction are usually associated with atherosclerotic plaque fissuring or ulceration at sites of coronary artery stenosis and subsequent development of a thrombus. This thrombus formation is initiated by platelet adhesion and aggregation; these, in turn, are promoted by
