For a graph , a wide range of transformations are possible. A graph can be converted into a new graph by adding vertices or edges following certain criteria. A graph derived from the parent graph by inserting a new vertex into each of its edge is known as subdivision graph and can be denoted as . The transformation graph of a graph can be defined as a graph whose vertex set is union of the vertex set

Meta-heuristic computing knacks for target angle estimation in monostatic radar system with coprime arrays Ain Shams Eng. J. (IF 6.0) Pub Date : 2024-02-14 Sadiq Akbar, Muhammad Sohail, Muhammad Asif Zahoor Raja, Fawad Zaman, Rizwan Ullah, Muhammad Abdul Rehman Khan, Nopdanai Ajavakom, Gridsada Phanomchoeng
Angle estimation of signals received by antenna arrays is a key step in adaptive beamforming, used to detect and locate targets in space. It is desirable to reduce costs by employing a smaller number of antennas while maintaining efficiency and degrees of freedom (DOF) of the system at the same time. Co-prime antenna arrays not only circumvent the operational constraints of cost and hardware complexity

A robust modified notch filter based SOGI-PLL approach to control multilevel inverter under distorted grid Ain Shams Eng. J. (IF 6.0) Pub Date : 2024-02-13 Praveen Bansal, Shishir Dixit, Saket Gupta, Majed A. Alotaibi, Hasmat Malik, Fausto Pedro García Márquez
This paper introduces a novel approach to enhance the control algorithm for a single-phase shunt active power filter(SAPF) by integrating a new technique into a 5-level cascaded multilevel inverter (MLI) with Photo Voltaic (PV) array integration. Due to the integration of non-linear loads in the grid, such as computers, variable speed drives, and other solid-state equipment, non-sinusoidal currents
