Small-scale agriculture is important. However, there are still limitations regarding the implementation of technologies in small-scale agriculture due to the high costs accompanying them. Therefore, it is essential to seek viable and low-cost solutio

Among various spectral analysis tools arisen in the last years, some were more prominent, such as Fourier transform, windowed Fourier transform and wavelet transform (WT). Nevertheless, all of them present implementation restrictions for an ideal ext

The oscillatory transient has well-dened characteristics such as short duration, considerable variations in the voltage’s amplitude, and frequency, which can be manifested in any part of an Electric Power System and mainly caused by the capacitor b

Spectral leakage is a phenomenon that is considered a problem and occurs when Discrete Fourier Transform (DFT) is used as a tool to identify harmonic components in a frequency spectrum of electric signals, which contains asynchronous sampling or inte

An Oscillatory Transient (OT) can occur in any part of an Electric Power System (EPS), and its basic characteristics are short duration and considerable variances of the amplitude of the voltage and frequencies involved. Focusing on a medium voltage

This work proposes a method for the selection of the optimized window of analysis for the Generalized S- Transform (GST), through an adaptation in the Particle Swarm Optimization (PSO) algorithm. The new version of the algorithm, called Adaptive Indi
