This thesis the ND method selective is introduced in order to reduce the computational effort of the DN method. It shows that there is always a reduction of calculations when you use this method. Also, shows that parallel ...

This thesis proposes a framework in the time domain to evaluate adverse phenomena to power quality, particularly, the harmonic content and the transient state in power systems. The main aim is to develop a methodology using ...

Semantic genetic operators in evolutionary algorithms, particularly in GP, have been proved to be a better heuristic than traditional syntactic operators by improving the performance of GP over certain problems. A semantic ...

In this research work is proposing a procedure from analysis and obtaining of the quasi-steady state model of some class of nonlinear singularly perturbed systems using bond graph. bond graph is a technique of modelling ...

This thesis proposes an approach to incorporate the mathematical models of wind turbine generators, automatic load frequency controls as well as voltage magnitude and frequency dependent loads into a weighted least ...

This thesis deals with the analysis of CUSTOM POWER devices to mitigate adverse power quality effects, such as sags, swells, harmonics and reactive power compensation. The mathematical model of DVR, DSTATCOM and back to ...

The current focus on the reduction of the environmental footprint from the energy sector throughout the world has motivated energy policy incentives promoting the optimal use of energy resources in the electricity production ...

In this work we discuss methods related to signal processing which are useful for characterizing and identifying audio in a robust way. These methods are addressed to discuss two of the fundamental problems in all audio ...

This thesis explores the use of qualitative reasoning to predict the behavior of a dynamical system given a change in one of its parameters based upon a qualitative representation of its bifurcation diagram. Three algorithms ...

This thesis focuses in a detailed electromechanical model, as a DAE (Differential-Algebraic Equations) mathematical structure, in state variables. The model integrates, the 123 characteristics of the mechanical subsystem ...
