Fault detection in microgrids presents a strong technical challenge due to the dynamic operating conditions. Changing power generation and load impacts current magnitude direction, which has an adverse effect on microgrid protection scheme. To address this problem, paper addresses field-transform-based fault method immune The faults are simulated via Matlab/Simulink model of grid-connected phot...

In this paper we investigate how the short-time Fourier transform can be extended in a Clifford setting. We prove some of main properties such as orthogonality relation, reconstruction property and reproducing kernel formula. Moreover, show effects modulating translating signal window function, respectively. Finally, demonstrate Lieb’s uncertainty principle for transform.

to date, a number of numerical methods, including the popular finite-difference time domain (fdtd) technique, have been proposed to simulate ground-penetrating radar (gpr) responses. despite having a number of advantages, the finite-difference method also has pitfalls such as being very time consuming in simulating the most common case of media with high dielectric permittivity, causing the for...

In this paper, we study channel estimation at a uniform linear array (ULA) with N antennas, where the ULA is composed of xmlns:xlink="http://www.w3.org/1999/xlink">L paths different angles arrival (AoAs). It assumed that Discrete-Time Fourier Transform (DTFT) beams (also known as xmlns:xlin...

Time-frequency concentration operators restrict the integral analysis-synthesis formula for short-time Fourier transform to a given compact domain. We estimate how much corresponding eigenvalue counting function deviates from Lebesgue measure
