In this article, we provide results on the existence and compactness of the set of solutions for a class of initial-value problem representing a first-order random impulsive differential equation. The key tool to achieve our goal is based on an alter

A class for systems of nonlinear second-order differential equations with periodic impulse action are considered. An urgent problem for this class of differential equations is the problem of the quantitative study (existence) in the case when the pha

The main goal of this article is to obtain the existence of solutions for a nonlinear system of a coupled Petrovsky–Petrovsky system in the presence of infinite memories under minimal assumptions on the functions g1,g2 and φ1,φ2. Here, g1,g2 are

Despite III-nitride and silicon carbide being the materials of choice for a wide range of applications, theoretical studies on their quaternary alloys are limited. Here, we report a systematic computational study on the electronic structural properti

Wurtzite III-phosphide GaP and GaAsP compounds have shown tunable direct band-gap making them promising candidates in a variety of future optoelectronic and photonic devices. We explore here, through DFT their corresponding electronic structure prope

This paper presents an experimental verification of an all-digital approach based on a deadbeat current control (DBC) algorithm for a three-phase shunt active power filter (shunt-APF), which provides fixed switching frequency operation and eliminates

In this paper we prove the existence of mild solutions for a second-order impulsive semilinear stochastic differential inclusion with a standard cylindrical Wiener process and Poisson jumps. We consider the case in which the right hand side can be ei
