14. Water resources integrated modeling supported by a geographic information system / Modelagem integrada de recursos hídricos com apoio de um sistema de informações geográficas
The relative or complete lack of water has been directing various actions in order to solve this problem. The national water resources politic (Law 9.433/97) with its five instruments for water resources planning and management can be considered the main action. Among these instruments, it is found the information system that has as purpose to collect, store

15. Distributed modeling and simulation of productive systems. / Modelagem e simulação distribuída de sistemas produtivos.
As tecnologias da informação, telecomunicações e mobilidade aliadas às mudanças econômicas e sociais acarretaram uma grande reestruturação da indústria. Entre estas mudanças, verifica-se um maior nível de descentralização e especialização das unidades produtivas, o aumento da automação dos processos e, em conseqüência, uma maior quantidad

17. Evaluation of the quality of the hydraulic fracturing models / Avaliação da qualidade dos modelos de fraturamento hidraulico
The purpose of this research has been evaluated three models of hidraulic fracturing. The first one, developed byFernandes [1998], is a semi-analytical model whose formulation is based on a constant rate of injection of fracturing fluid. This model presents as advantage the simplicity of the calculations and the immediate attainment of the results, on the ot

19. Proposta de mobilidade para protocolos H.323 e SIP em telefonia IP, utilizando linguagem de especificação formal SDL orientada a objetos
This work describes some proposals for mobility extension to H.323 and SIP protocols. The new proposals for H.323 involve intrazone and interzone mobility, and interzone mobility using resources with new entities, signallings and functions from H.510. Based on the mobility solution developed by Liao, these new systems have demonstrated how H.323 could be ext
