3. DECISION SUPPORT SYSTEM FOR USE IN AGRIBUSINESS (SADA): TELEMETRY AND DATA PROCESSING PERFORMANCE OF MACHINE HARVEST / SISTEMA DE APOIO À DECISÃO PARA UTILIZAÇÃO NO AGRONEGÓCIO (SADA): TELEMETRIA E TRATAMENTO DE DADOS DE DESEMPENHO DE MÁQUINA DE COLHEITA
To obtain higher profitability in farms, it is essential to proper management of the operations performed, caused by concern over the operational cost of the machines used, which represents a high percentage compared to total costs of operation and can be up to forty percent. This cost can be reduced if the use of machinery is optimized, improving performanc

4. A FAULT TOLERANT MECHANISM FOR WORKFLOW MANAGEMENT SYSTEMS / UM MECANISMO DE TOLERÂNCIA A FALHAS PARA SISTEMA DE GERENCIAMENTO DE WORKFLOW
In this work we propose a mechanism for failure detection, group management and service replication, providing fault tolerance for workflow management systems. Workflow management systems require specific replication features, since such systems deal with non-deterministic operations and update their s internal state without any external calls. As a case stu

5. Raciocínio baseado em casos aplicado ao gerenciamento de falhas em redes de computadores / Case-based reasoning applied to fault management in computer networks
Com o crescimento do número e da heterogeneidade dos equipamentos presentes nas atuais redes de computadores, o gerenciamento eficaz destes recursos toma-se crítico. Esta atividade exige dos gerentes de redes a disponibilidade de uma grande quantidade de informações sobre os seus equipamentos, as tecnologias envolvidas e os problemas associados a elas. S

6. Um discriminador inteligente de eventos de rede para o ambiente CINEMA / A network events intelligent discriminator for the CINEMA environment
Com o crescimento das redes de computadores e, principalmente, de sua importância para as organizações, o gerenciamento de redes tornou-se fundamental. Contudo, o gerenciamento de redes é um processo difícil dada sua complexidade e mudanças freqüentes em sua configuração. O ideal seria que sistemas pudessem fazer o trabalho de administradores de red

7. Entidades não lucrativas de Uberlândia: um estudo psicanalítico sobre a lógica discursiva solidária diante das novas formas de subjetivação
The theme of this dissertation involves the non-profit entities, represented mostly by NGOs, using them as a focal point for discussion of solidarity inherent to their speeches. Returning to the political, historical and social giving rise to such civil society initiative, weve found many factors that led us to realize a social process of politicization sinc

9. Incorporação quantitativa de dados de sismica 4D no processo de ajuste de historico / Quantitative incorporation of seismic 4D in history matching process
Good decision making related to oilfield management depends on reliability of production forecast which demands calibrated reservoir simulation models. Due to the complexity of the production history matching process, there are many models with reasonable match but, many times, with different forecasts, mainly due to important heterogeneities that are not ob

10. PRIORIZAÇÃO DOS MODOS DE FALHA DE EQUIPAMENTOS UTILIZANDO OS MÉTODOS DE ANÁLISE MULTICRITÉRIO PROMETHEE E FUZZY PROMETHEE / PRIORITIZATION OF FAILURE MODES OF EQUIPMENT USING THE METHODS OF MULTICRITERIA ANALYSIS PROMETHE AND FUZZY PROMETHE
Aiming to meet the criteria of availability and reliability required by the rules of the Brazilian electric sector, energy companies have increased the use of systems for monitoring and diagnosis. This allows the identification of prior evidence of abnormalities in the operational condition of substation equipment, enabling the practice of predictive mainten

11. A descentralized P2P middleware for workflow computing / Um middleware Peer-to-Peer descentralizado para a computação de workflows
P2P Computing has been raised as an alternative and complementary solution to Grid Computing. The use of P2P technology is able to provide a flexible and decentralized execution and management of Grid workflows. In this work we present a completely decentralized P2P middleware for workflow computing. The middleware collects the shared processing power of the
