25. Dynamic bandwidth allocation for EPON networks / Alocação dinâmica de largura de banda em redes EPON
Telecommunication networks are divided into core, metropolitan and access networks. The core and metropolitan networks use high capacity bandwidth optical fibers, while the access networks have bandwidth bottlenecks because of the use of twisted-pair wires and coaxial cable. To solve this problem and to offers the users broadband access at low cost the use o

27. Molecular Epidemiology of the virus of the imunodeficiência human being type 1 (HIV-1) in cities of the interior of the State of Rio de Janeiro, with emphasis in the cities of Miracema, Santo Antonio de Pádua and Saquarema, 2001 the 2006. / Epidemiologia Molecular do Vírus da Imunodeficiência Humana Tipo 1 (HIV-1) em Municípios do Interior do Estado do Rio de Janeiro, com Ênfase nas Cidades de Miracema, Santo Antonio de Pádua e Saquarema, 2001 a 2006.
The AIDS epidemic in Brazil is spreading from the large urban centers to small cities and the innermost parts of the country, yet data on the features of HIV-1 infection in these places are scarce. Such spread is expected to pose formidable medical, social and logistic challenges. By using mainly HIV-1 envelope and polymerase genomic regions, the studies tha

29. Operação otimizada do sistema adutor metropolitano utilizando algoritmos genéticos: estudo de caso - SAM Leste da Região Metropolitana de São Paulo (R.M.S.P.). / Optimized operation of metropolitan mains system using genetic algorithms: case study - East Metropolitan Mains System of Metropolitan Region of São Paulo (M.R.S.P.).
This work presentss an evaluation of optimization of real time operation of a complex water supply system. Genetic Algorithm associated with a SCADA system and a network hydraulic simulation model was applied. Observed historic consumptions were used as a perfect water demand forecast model. Case study is the optimization of a multiobjective function (energy
