16. Voltage Dip (Sag) Estimation in Power Systems based on Stochastic Assessment and Optimal Monitoring
Abstract : This dissertation deals with the statistical characterization of the performance of power systems in terms of voltage dips (sags). It presents a method named voltage dip estimation that extends monitoring results to buses not being monitored. READ MORE

17. Thermal System Analysis : heat transfer in glass forming and fluid temperature-control systems
Abstract : Thermal system analyses are often required, and conducted, in engineering problems in almost all engineering disciplines. The methods employed vary a great deal and must be specially adapted for each situation. Basically, two different methods are used, namely distributed modelling and lumped parameter modelling.

19. Dynamic Power System Load -Estimation of Parameters from Operational Data
Abstract : The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. READ MORE

20. An Integrated System-Level Design for Testability Methodology
Abstract : HARDWARE TESTING is commonly used to check whether faults exist in a digital system. Much research has been devoted to the development of advanced hardware testing techniques and methods to support design for testability (DFT). READ MORE
