Improved Unified Power Quality Conditioner Design and Numerical Simulation for Power Quality Improvement
Abstract: Harmonic currents can distort the waveform voltage, resulting in a weak signal. There is also an increase in the number of loads requiring enough sinus tension to function properly. As electronic devices become more power-sensitive, people are becoming increasingly interested in power conditioning solutions. Therefore, if the amount of electricity being generated falls below a certain threshold, some type of compensation must be provided. Unified Power Quality Controller (UPQC) is …

Algebraic Foundations of Generalized Signal Processing: A Unified Approach Across Domains
Abstract: Using the techniques of algebra, notably polynomial algebras and modules, algebraic signal processing (ASP) is a contemporary, abstract framework that generalizes conventional signal processing— including Fourier analysis, filtering, and convolution. The notion is to use algebraic structures to explain signals, systems, and transformations such that ideas may be understood and generalized across many domains, including time, space, graph, or group. A unifying theoretical framework called ASP generalizes classical signal processing …
