However, elimination of voltage and current quality issues in a grid connected Photovoltaic (PV) system is essential.

Forecasting random perturbations allows improving the control quality in intelligent transport systems and ensuring the efficient operation of diagnostic systems. Several works are known where extrapolator models based on Chebyshev polynomials orthogonal on equidistant points are presented. These models use a predictive polynomial whose coefficients are computed using the least squares criterion. Additionally, an analysis of forecast errors for random stationary input signals has been conducted. At the same time, in the case of non-stationary input signals, singular perturbations may occur, th

Abstract:
Phased-locked arrays of diode lasers have been reported as early as 1978.(1) However, very rarely have the beam patterns of arrays displayed the desired result: a single, diffraction-limited beam in both cw and pulsed operation. Initially, the problem has been that arrays were made of gain-guided devices, that is, devices for which lateral optical-mode confinement is solely provided by the injected-carrier profile. Gain-guided devices are thus intrinsically vulnerable to gain-profile changes due to drive condition changes (i. e. cw or pulsed), spatial hole-burning at high drive levels above th
