Análise de múltiplas fontes VoIP adaptativas
| Posted on: 15 mar. 2007This work performs an analysis of several VoIP sources, where the sources are capable of adapting their transmission rates. This analysis is based on the network parameters (packet loss rate, end-to-end delay and jitter), ... -
Uma implementação de semântica operacional estrutural modular em Maude
| Posted on: 27 mai. 2005This dissertation presents a formal tool for Modular Structural Operational Semantics (MSOS), based on the conversion from MSOS to Rewriting Logic recently developed by Braga and Meseguer. The implementation, named Maude ... -
Integração de serviços de monitoração e descoberta de recursos a um suporte para arquiteturas adaptáveis de software
| Posted on: 24 nov. 2006Ubiquitous, pervasive and self-adaptive distributed systems have specific requirements regarding the resources to be used by the infrastructure or by the components of the applications. Morover, auto-adaptive, ubiquitous ... -
MyEasyGridPortal: uma abordagem para facilitar o acesso a múltiplas grades computacionais usando a tecnologia Portlet
| Posted on: 20 dez. 2006The falling costs and steady increases in processing capacity and data storage of personal computer, as well as throughput improvements on local networks have stimulated the idea of using such non-specialized computers to ... -
