16. Novas arquiteturas para detecção de plágio baseadas em redes P2P
Nowadays the Internet has become a reference on information retrieval, thanks to its large amount and easiness to access it. But this can be misused, as one can simply access an information and take it as his own authorship. This constitutes an act of plagiarism. It has become increasingly common for people to do this, and tools to prevent this are in need.

17. Hermes: a framework for P2P application programming / Hermes: um arcabouço para a programação de aplicações P2P
Hermes is a framework for P2P application programming. Using it, one can create several kinds of distributed applications without worrying about the underlying network. Hermes is not a P2P overlay network implementation, but a shell envolving existing implementations. The application developer is isolated from the implementation of the overlay network in use

18. Estratégias de gerenciamento de banda IP/MPLS para o transporte eficiente de serviços integrados
To use the network resources in the optimal efficiency one possibility is apply resource management policies that can be flexible and feasible as much as the time period can be. The converged networks are expected to deliver audio and video transmissions with quality as good as that of a circuit switching network. In order to make it possible, the network mu

20. Search and sharing software components in peer-to-peer networks / Busca e compartilhamento de componentes de software em redes peer-to-peer
Peer-to-peer (P2P) architectures have become a very attractive alternative to make the Internet more accessible. This approach has been widely used, from content sharing programs through communications systems, which has provided the P2P networks with considerable improvements in the technology and methodologies related. In this context, the current work pre

23. A proposal of videoconference technology integrating grid technologies. / Uma proposta de tecnologia para videoconferência integrando tecnologias grid.
The development of videoconferencing without the use of equipments with customized technology or without commercial networks (like Internet 2) or without common characteristics (as Multicast, for instance) has appeared as a challenge to the subject researchers. This work presents a proposal of solution to this problem, showing that is possible to create a vi

24. Vegetal bioindicators of atmospheric pollution: a contribution to community health / "Bioindicadores vegetais de poluição atmosférica: uma contribuição para a saúde da comunidade"
Air quality in urban and industrial areas tends to present undesirable concentrations of contaminants, without the availability of a broad monitoring system, given the sophistication of conventional physical-chemical methods, which require high expenditure for implantation, operation and maintenance. These costs can be reduced by the adoption of the compleme
