1. ARTIFICIAL NEURAL NETWORK AND WAVELET DECOMPOSITION IN THE FORECAST OF GLOBAL HORIZONTAL SOLAR RADIATION
This paper proposes a method (denoted by WD-ANN) that combines the Artificial Neural Networks (ANN) and the Wavelet Decomposition (WD) to generate short-term global horizontal solar radiation forecasting, which is an essential information for evaluating the electrical power generated from the conversion of solar energy into electrical energy. The WD-ANN meth

2. Solução de problemas de otimização utilizando arquitetura híbrida. / Solution of optimization problems using hybrid architecture.
Electrical power could be considered as one of the economy propulsion vector of a country, assuming extremely important and strategic role because it makes direct influence to the production capacity. The expansion of electrical energy production could not only be done in a short time because constructions in this area take many years and could require more

3. OUTFLOW FORECAST BASED ON ARTIFICIAL NEURAL NETORKS AND WAVELET TRANSFORM / PREVISÃO DE VAZÃO POR REDES NEURAIS ARTIFICIAIS E TRANSFORMADA WAVELET
The hydroelectricity system is responsible for 83.7% of the electric energy generated at Brazil. Therefore, the generation of electric power in Brazil depends basically on the natural flow rates distributed by twelve basins in the country. The quality of prediction of natural flow is of crucial importance for the Brazilian governmental agency, ONS (from the

5. Point of colapse method applied to the analysis of critical contingencies in electrical power systems / Método do ponto de colapso aplicado na análise de contingências críticas em sistemas elétricos de potência
The constant complexity increase of the electrical power systems demands a continuous improvement of operation and control techniques. The current supervision and control centers are characterized by functions that process collected real-time information, in order to effectively control the systems and to keep them operating in accordance with a specified sc
