Gerenciamento Temporal de Versões para Evolução de Esquemas em BDOO

The use of versions has been essential in several database applications, allowing the storage and the handling of different database states. During the schema evolution, versioning is used to preserve all schema versions, as well as their instances. On the other hand, bitemporal database concepts, that incorporate transaction and valid timestamps, provide flexibility to schema evolution mechani...

Um Padrão Canônico para Controle de Paralelização em Aplicações de e-Science

The use of workflow control-flow patterns in e-Science applications results in productivity improvement, allowing the scientist to concentrate in his/her own specialization area. However, the use of workflow control-flow patterns for execution in grids remains an opened question. This paper describes a canonical pattern compliant to parallelization scenarios, commonly found in e-Science applica...

Mecanismos de Controle de Admissão Baseado em Medições em Redes IEEE 802.11e

Although the 802.11e extension of the IEEE 802.11 standard for wireless local area network was concerned to provide Quality of Service, such provisioning cannot be achieved without specific traffic control mechanisms. In this paper, the use of admission control based on measurement for QoS provision in 802.11e networks is evaluated. It is shown that QoS differentiation can be obtained with the ...
