1. Thermophysical and Transport Properties of the BaCl2-CsCl High Temperature Ionic Liquid Mixtures
High temperature ionic liquids (HTILs) densities and transport properties for mixtures BaCl2 CsCl, x(BaCl2) = 0-1, have been studied as a function of composition and temperature. In terms of Arrhenius theory, the temperature correlation of all measured properties was made and discussed. Thermodynamic properties (isothermal compressibility, molecular volume,

3. Identification and agreement of first turn point by mathematical analysis applied to heart rate, carbon dioxide output and electromyography
BACKGROUND: The second heart rate (HR) turn point has been extensively studied, however there are few studies determining the first HR turn point. Also, the use of mathematical and statistical models for determining changes in dynamic characteristics of physiological variables during an incremental cardiopulmonary test has been suggested. OBJECTIVES: To

4. Implementação paralela do algoritmo iterativo de busca do parâmetro de regularização ótimo para o funcional de Tikhonov no problema de restauração de imagens / Parallel implementation of the iterative algorithm to search the optimal regularization parameter for the Tikhonov functional problem in image restoration
The use of techniques with the functional of Tikhonov in image processing has been widely used in recent years. The basic idea in this process is to modify an initial image using a convolution equation and to find a parameter which minimizes the function in order to obtain an aproximation of the original image. However, a typical problem in this method consi

5. Analyzing genotype-by-environment interaction using curvilinear regression
In the context of multi-environment trials, where a series of experiments is conducted across different environmental conditions, the analysis of the structure of genotype-by-environment interaction is an important topic. This paper presents a generalization of the joint regression analysis for the cases where the response (e.g. yield) is not linear across e

6. ALGORITMOS PARALELOS PARA MOTORES DE JOGOS EM MULTIPROCESSADORES / PARALLEL ALGORITHMS FOR MULTICORE GAME ENGINES
This thesis presents several techniques about parallel technology on electronic games. The thesis begins presenting several possible architectures for a game engine. A new architecture is presented, more flexible and adequate for the processors of the future that will have a higher level of parallelism. Following, a new technique for processing an octree, a

7. ChipCFlow - partioning and communication protocol in the dynamic dataflow graph / ChipCFlow - Partição e protocolo de comunicação no grafo a fluxo de dados dinâmico
This work describes the concept of an approach that uses data ow computational model, inherently parallel, associated with de reconfigurable computing model, partial and dynamic, in order to obtain high performance computational systems. More specifically, it is about a model to the partitioning and communication between partitioned sectors of a CDFG (Contro

8. LALP: a language for parallelism of loops exploitation in reconfigurable computing / LALP: uma linguagem para exploração do paralelismo de loops em computação reconfigurável
Reconfigurable computing is becoming increasingly important in embedded and high-performance computing systems. It allows performance levels close to the ones obtained with Application-Specific Integrated circuits (ASIC), while still keeping design and implementation flexibility. However, to efficiently program devices, one needs the expertise of hardware de

9. Estratégias de computação seqüenciais e paralelas sobre espaços coerentes / Sequential and parallel computational strategies of coherence spaces
As estruturas de dados concretas (cds) são quaternas (C, V, E, l-) que contêm um conjunto C de células, um conjunto V de valores, um conjunto E de eventos e uma relação de habilitação l-. O conjunto de estados de uma cds é um domínio concreto que pode ser considerada a parte "abstrata" das cds. Da mesma maneira tem-se que os domínios de eventos (qu

Comparing the periodontal bone defects, through data obtained with radiographies by the parallelism periapical te chnic, using the conventional and digital images. To obtain the images a x-ray device of the brand Dabi Atlante was used, where the radiographic exam was standardized to obtain a digital and conventional image with the best in detai l and the lea

11. Uma ferramenta para execução de algoritmos utilizando o modelo a fluxo de dados dinâmico em hardware reconfigurável para a arquitetura ChipCflow: módulo de conversão C em grafo a fluxo de dados / A tool for algorithms implementation using the dynamic data flow model in reconfigurable hardware for the ChipCflow architecture - C conversion to data flow graph module
ChipCflow is a tool for algorithms execution using a data dynamic flow in reconfigurable hardware. The main purpose of the work is to use the data flow architecture model, associated to the concept of reconfigurable architectures, to speed up C written applications. The program acceleration happens in the most intensive processing parts (example: loops), thr

12. Sequential and parallel approaches to reduce the data cube size.
Since the introduction of Data Warehouse (DW) and Online Analytical Processing (OLAP) technologies, efficient computation of data cubes has become one of the most relevant and pervasive problems in the DW area. The data cube operator has exponential complexity; therefore, the materialization of a data cube involves both huge amount of memory and substantial
