2. 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

3. Analysis of criteria for closely-spaced parallel runway approaches applied to a multiple airport system.
In order to increase arrival rates at many of today s heavily congested airports, simultaneous approaches are conducted on parallel runways. For many years, the FAA has permitted simultaneous independent instrument approach operations only for those parallel runways with a minimum separation of 4300 feet. Nowadays, new criteria have been developed to increas

6. AvaliaÃÃo econÃmica da substituiÃÃo de um chiller de compressÃo por um chiller de absorÃÃo alimentado por coletores solares com base em mediÃÃes em um prÃdio da Chesf em Recife
The perspective of rising costs for electrical energy and fossil fuels, together with more efficient solar colectors and absorption chillers, stimulates for the retaking of the analisys towards the utilization of solar refrigeration systems, mainly in regions with good insolation characteristcs, like Northeast Brazil . Considering this context, this document

7. Aplicação da tecnologia de agentes de planejamento em operações de satélites / Applying the planning agent tecnology in satellite operations
Research for automatic solutions for space operations is a real need for all space agencies in order to reduce space mission costs. Nowadays, a significant parcel of satellite operation activities at the National Institute for Space Research (INPE) is still performed manually. Finding automated alternatives for the satellite operation activities at INPE is a

8. Alocação de Tarefas Paralelas Comunicantes em Ambientes Distribuídos Heterogêneos
Distributed systems have been widely used in the resolution of problems that demand a large amount of processing time, because they allow the simultaneous utilization of many computational resources. Many machines with a distributed architecture have been proposed during the years. Among these are computer clusters, which are distributed systems composed of

9. Evaluation of memory load indices on distributed computing systems / Avaliação de índices de carga de memória em sistemas computacionais distribuídos
This work presents an analysis of the behavior of load indices related to memory usage and activity. It describes 11 indices which reflect memory load, directly or indirectly. These indices may be easily obtained on the GNU/Linux operating system using the /proc filesystem. A monitoring tool has been developed to make the behavior analysis easier, but it can

10. Controle dinâmico de recursos em sistemas operacionais
One of the main functions of the operating systems is to manage the computer resources. A network operating system has the same duty, however, the quantity of resources that should be manage is bigger. Even so, COTS operating systems supply only limited mechanisms of resources management, where is not possible impose contraints or privileges of access to the

11. Um estudo do desempenho dos protocolos iSCSI e Fibre Channel
Nowadays, most of the corporations face a growing demand for efficient methods to manipulate information. Applications are becoming more sophisticated with richer content and consequent there is the need for more storage and faster access to information. In the past, storage systems and computer networks were two independent entities, but due to the huge dem

12. PROCESS CONTROL SYSTEMS : DEPENDABILITY AND PERFORMANCE MODELING
Today, a wide variety of computer systems are required to react automatically to various events generated by external processes and/or human operators. An important class of these process control systems, called hard real-time systems, need to respond to events under severe timing constraints expressed in terms of deadlines and earliest starting times. In ge
