1. Proposição de um modelo para análise de fluxo de carga, curto-circuito e simulação de relés de produção
O presente trabalho objetiva ao desenvolvimento de um modelo para simular redes de energia elétrica em regimes transitório e permanente, utilizando o software ATP (Alternative Transient Program), para servir como elo entre dois temas distintos, presentes na metodologia clássica de planejamento de redes: a análise de curtos-circuitos e o estudo de fluxo d

2. Determinação da rigidez e amortecimento equivalente proveniente do fluido escoando e interagindo com placas flexiveis : teoria e constatações experimentais
The understanding and modelling of the stiffness and the damping behavior of structures when subjected to a flow field, is still a very complex problem, dealing with the interaction of two major fields of mechanical sciences. The classical theory of elasticity deals with strains of flexible bodies under predefined external loads. Generally, the external load

3. Numerical simulation of a two-stage turbine for turbopumps of liquid propellant rocket engine.
The main aim is to understand the gas dynamic process, which occurs inside a two-stage turbine and to propose an algorithm for the simulation of a two-stage turbine at design and off-design points. The explanation of each chapter is constructed to make further works easy, which should be the main of any research work that needs to be continued. Moreover, the

4. Escoamento bifasico anular vertical ascendente : inversão do sentido do fluxo do liquido
The flow reversal and its application to gas-well load-up was investigated in a 27 mm ID cylindrical vertical pipe with air-water flows. The experimental flow loop was validated for flooding data. Flow reversal experimental data include mean film thickness, dispersion rate, pressure drop, void fraction and co-current and counter-current flow rates. A model f

5. PROBABILISTIC POWER FLOW: THEORY AND APPLICATION / FLUXO DE POTÊNCIA PROBABILÍSTICO: TEORIA E APLICAÇÃO
A Probabilistic Power Flow Algorithm (PPF) allows the practical evaluation of the probability of occurrence of power system events, based on their historical performance, load forecast and availability of generating units and transmission equipment. Such events are overlads, undervoltages, overvoltages and indufficiency of active/reactive power generation. T
