1. Aerobic and facultative microorganisms isolated from corroded metallic structures in a hydroeletric power unit in the Amazon Region of Brazil
Aerobic and facultative bacteria belonging to the Enterobacteriaceae, Pseudomonadaceae, Bacillaceae, Corynebacteriaceae and Streptococcaceae families have been isolated from corroded metallic structures of a hydroelectric power unit in the Amazon region of Brazil. In addition to anamorphic dematiaceous and moniliaceous fungi, members of the archeobacteria

2. Metodologia de prospecção de pequenas centrais hidrelétricas. / Small hydroeletric power plant prospection methodology.
Ao longo das últimas décadas, centenas de usinas hidrelétricas de todos os portes foram construídas no Brasil, sendo que as centrais hidrelétricas de pequeno porte foram os embriões deste desenvolvimento e recentemente assumiram papel de destaque com as mudanças ocorridas no setor elétrico iniciadas em meados dos anos 90. Através do estudo de aspect

3. Metodos de pontos interiores aplicados ao problema de pre-despacho de um sistema hidroeletrico com manobras programadas / Interior point methods applied the predispatch problem of a hydroeletric system with schuduled mancuver
In this work, the prima-dual interior point methods are used to minimize the DC predispatch generation and transmission costs on hydroeletric systems with previously scheduled maneuver. A study of the matrix structure is also performed considering the changes that occurs in the system after maneuvering. A function, developed in Matlab that controls the maneu

4. Modelo de suporte a decisão para o otimização da operação de sistema de usinas hidroeletricas / A decision support tool for the optimization of the operation of a system of hydro-eletric plants
This dissertation has the objective of build a Decision Support Tool that gives a quick and easy way to analyze all the different alternatives to manage integrated a complex of hydroelectric reservoirs seeking the maximization of the benefits of the complex. The benefits of the complex were defined as the total potential gravitational energy of the hydraulic

6. Avaliação dos métodos de levantamento do meio biológico terrestre em estudos de impacto ambiental para a construção de usinas hidrelétricas na região do cerrado / Evaluation of the methods of survey of the terrestrial biological way in studies of ambient impact for the construction of hidrelétricas plants in the region Cerrado, in Brazil
Environmental impact assessments (EIAs), and presentation of these reports have been used in Brazil since the 1970's in a non-formal manner, that is, without pertinent legislation to minimize the impact of large enterprises. With the rise of these studies, they were then ruled, nationally, by the CONAMA 001 resolution, 23/01/1986. To perform the EIA, a s

7. Impactos no sistema de proteção da rede de distribuição com a ligação de pequenas centrais hidrelétricas. / Impacts of small hydroeletric power plants on the distribution protection systems.
Geração Distribuída é uma expressão utilizada para designar a geração elétrica proveniente de locais próximos ou juntos de consumidores, não interferindo a potência, tecnologia ou fonte de energia empregada. Estudos indicam que, até o ano de 2010, 20% do total de geração (em termos mundiais) serão provenientes desta forma de obtenção, uma ve

8. REPRESENTATION OF MULTISTAGE STOCHASTIC PROBLEMS IN DECOMPOSITION: AN APPLICATION IN PLANNING OF THE EXPANTION OF ELECTRIC POWER SYSTEMS / REPRESENTAÇÃO DE PROBLEMAS ESTOCÁTICOS MULTI-ESTÁGIOS EM DECOMPOSIÇÃO: UMA APLICAÇÃO AO PLANEJAMENTO DA EXPANSÃO DE SISTEMAS DE ELÉTRICOS
The objective of this paper is to present a new methodology for the solution of hydrothermal systems expansion planning problems that takes into account uncertainties of future water inflows to the system reservoirs. The problem consists on the determination of a set of hydroeletric and thermoelectric plants that will be constructed in order to minimize the
