15. Simulação transiente de um sistema de refrigeração doméstico: análise paramétrica / Transient simulation of a domestic refrigeration system: parametric analysis
In the present work are presented transient numerical simulation results of a vapor compression domestic refrigeration system considering the procedure described by JAKOBSEN (1995). The employed mathematical model is based on first order differential-algebraic equation (DAE) systems, obtained from energy balance in the different components of the refrigerati

17. Análise de dimensionamento estocástico e determinístico de sistemas fotovoltaicos isolados / Stochastic and deterministic sizing analysis of stand-alone photovoltaic systems
This paper presents the photovoltaic systems modeling (photovoltaic generators and batteries) and a new methodology for the sizing of stand-alone photovoltaic systems using a stochastic method, comparing it to the existing deterministic methods. Softwares were developed for the stochastic and deterministic sizings, the probabilistic one being composed of fou

18. DEVELOPMENT OF AN INTERFACE IN SIG FOR SUPPORT TO THE HYDRAULICAL SIZING OF SYSTEMS OF WATER SUPPLY / Desenvolvimento de uma Interface em SIG para Suporte ao Dimensionamento Hidráulico de Sistemas de Abastecimento de Água
The studies in water resources are models that need data gotten in the maps or research of field. Recently, these information are being added directly in Geographic Information System (GIS) due to the technological advances developed by these systems and to the continuous improvements in digital land model. Currently, efforts have been carried through to dev

21. Sizing hydropower plants via evolutionary optimization techniques / Dimensionamento de usinas hidroelétricas através de técnicas de otimização evolutiva
As metodologias normalmente utilizadas para otimizar as dimensões de uma usina hidroelétrica, incluindo os métodos empregados pelo Setor Elétrico Brasileiro, baseiam-se em análises do tipo custo/benefício. Os custos provêm de gastos diretos com a construção da usina e os benefícios correspondem a receitas proporcionadas pela venda de energia. Para
