1. AGST (Autonomic Grid Simulation Tool): uma ferramenta para modelagem, simulação e avaliação de abordagens autonômicas para grades de computadores / AGST (Autonomic Grid Simulation Tool): a tool for modeling, simulation and evaluation of autonomic approaches to grids of computers
Computer Grids are characterized by the high dynamism of its execution environment, resources and tasks heterogeneity, and high scalability. These features turn tasks such as configuration, maintenance and failure recovery quite challenging and is becoming increasingly difficult to perform them only by human agents. The autonomic computing term denotes compu

2. Grades computacionais baseadas em modelos economicos / Grid computing based on economic models
Grid computing is a paradigm that allows the sharing of heterogeneous resources, geographically distributed and under independent administration. Sharing must be done to optimize the use of resources and meet quality of service requirements. Economic models can be applied to provide a fair allocation of these resources and to promote the entry of a greater n

3. Simulador eletromagnético em um ambiente de grades computacionais / Eletromagnetic simulator in a grid computing environment
The aim of this work is to develop the Pre and Post-Processing stages from an electromagnetic simulation suite, called SSAR-BR, and also a grid computational environment, which permits the execution of large electromagnetic problems. The processing stage, based in the Finite Difference Time Domain (FDTD) method, has been already developed as part of a doctor

4. An environment for distributed and parallel object-oriented programming for grid computing. / Um ambiente para programação orientada a objetos distribuídos e paralelos em grades computacionais.
Grid computing is already a reality both in academic and business world. Its use has become popular mainly because of the projects in this area and the advertising of products and software that offer this idea. Nevertheless, environments for development of object-oriented applications in Java for grid infrastructure are still scarce. Some initiatives offer l

5. Strategies for computational resources trading in desktop grids / Estrategias para comercialização de recursos computacionais em desktop grids
The association of idle machines in desktop grids architectures represents a significant progress in the solution of complex problems in areas as science, engineering, trade and others. The difficulty in the implementation and in the continuity of these architectures is to maintain the levels of availability demanded by their users. In its majority, the user

6. Um middleware para execução de processos estruturados em grades computacionais / A middleware for execution of structured processes in computer grids
O conceito de grade surgiu com a necessidade crescente de se aproveitar recursos computacionais disponíveis em uma ou mais organizações para resolver problemas que exigem compartilhamento de dados e um grande poder de processamento. Uma grade computacional tem como objetivo principal permitir a execução distribuída e paralela de tarefas em recursos com

7. Security in grid computing / Segurança em grades computacionais
Grid computing is a concept that exploits the power of computer networks, with the specific aim of making virtual layers available that allow users to have access to highly demanding applications, as well as to adhere to large scale, highly diverse, virtual communities. Grid computing provides support for the execution of parallel applications, grouping toge

8. Engenharia de trafego multi-camada para grades / Multi-layer traffic engineering for grid networks
Grids are dynamic and heterogeneous computing environments which require systematic methods for minimizing the execution time of applications. Such methods needs to detect changes on resource availability so that the execution time of applications can be kept low. The method introduced in this dissertation considers changes on the availability of hosts as we

9. Uma nova arquitetura para a representação das regras de negócio em modelos de objetos dinâmicos / An new architecture for representing business rules in dynamic object models
A Divisão de Desenvolvimento de Sistemas de Solo (DSS) sempre desenvolveu os sistemas de controle para os satélites do INPE com arquiteturas que permitissem que os mesmos fossem re-usados por futuros satélites com um conjunto reduzido de mudanças. O desafio que se apresenta é construir um sistema de controle adaptativo, usando a tecnologia de Objetos Di

10. Uma nova arquitetura para a representação das regras de negócio em modelos de objetos dinâmicos / An new architecture for representing business rules in dynamic object models
The Ground System Development Division (DSS) at INPE has always developed satellite control systems with architectures that may be used as much as possible by future satellites. The present challenge is to build an Adaptive Satellite Control System, using the technology of the Dynamic Object Model, so as to comply with later requirements without having to ma

12. SimulaÃÃo de reservatÃrio de petrÃleo em arquiteturas paralelas com memÃria distribuida
New codes have been developed for the solution of large scale models in reservoir simulations with high performance computing. This work shows the development of a petroleum reservoir simulator using distributed memory models for parallel computers. A two phase oil/water Black-Oil model was implemented and the resulting equations are discretized by ânite di
