13. SERVIÇO DE COLABORAÇÃO PARA A ARQUITETURA CLINICSPACE / COLLABORATION SERVICE TO CLINICSPACE ARCHITETURE
Ubiquitous Computing or Pervasive Computing is a new paradigm that aims to provide information and communication technology accessible anywhere, by anyone, available anytime, where computational resources should be integrated into the physical environment in a transparent manner. One of the areas of research on pervasive computing infrastructure is related t

14. SCAE: uma abordagem baseada em agentes inteligentes para gerenciamento e controle de campos de petróleo / SCAE: an approach based on intelligent agents for management and control of oil fields / SCAE: uma abordagem baseada em agentes inteligentes para gerenciamento e controle de campos de petróleo / SCAE: an approach based on intelligent agents for management and control of oil fields
Several existing systems, whether in nature, whether in companies human exhibit the characteristic of being formed by individuals or subsystems that cooperate to carry out their tasks, and thus achieve a global goal. Examples these systems range from a society of bees to an organization financial, community animal to a manufacturing system, among many others

15. Dynamic load-balancing : a new strategy for weather forecast models
Weather forecasting models are computationally intensive applications and traditionally they are executed in parallel machines. However, some issues prevent these models from fully exploiting the available computing power. One of such issues is load imbalance, i.e., the uneven distribution of load across the processors of the parallel machine. Since weather

16. Geração automática de código para a execução em um ambiente de computação em DataFlow
The computers architectures are becoming more distributed and hierarchical,that is, there exist lots of computers in a cluster and there are many processors in these computers and these processors have multiple cores. Many models have been proposed to explore the features of the computers architectures. The Data-flow computing models stand out among the prop

17. A new architectural approach for interoperability of real-time system components.
Interoperability is a key property of distributed applications, which is hard to achieve due to the large number of interoperating components and semantic heterogeneity. Distributed Real-Time Systems (RTS) have strict requirements of performance. The interoperability of Distributed RTS components challenges the computer engineering community to fulfill these

18. 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

19. Análise de mecanismos de replicação de dados para grades de computadores / Analysis of data replication mechanisms for grid computing
A datagrid is an distributed computing environment designed to aggregate and share storage resources that are geographically distant. Datagrids provides infrastructure and services for discovery, transfer, handling and managing large amounts of data stored in distributed repositories. The datagrids share characteristics with peer-to-peer networks, distribute

20. Integração de bancos de dados heterogêneos utilizando grades computacionais. / Heterogeneous databases integration using grid computing.
Bancos de dados normalmente são projetados para atender a um domínio específico de uma aplicação, tornando o acesso aos dados limitado e uma tarefa árdua em relação à integração de bancos e compartilhamento de dados. Existem várias pesquisas no intuito de integrar dados, como a criação de softwares específicos para uma determinada aplicação

21. 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

22. Proposta de melhoria de tempo de resposta para o protocolo FTT-CAN : estudo de caso em aplicação automotiva
Embedded computing systems have become widely used in many areas. The greater part of those systems has time constraints and therefore they can be characterized as real time embedded systems. Nowadays, distributed computing has reached the embedded application, where some fieldbuses are already being used as communication platforms. Some important researches
