An efficient compensation method is proposed for the reduction of mutual coupling among elements an antenna array using optimum current amplitude excitation weights. The performance degrades heavily due to coupling. effect can neither be eliminated nor ignored in context design. Several analytical and numerical techniques have been past few decades calculation effect. Here, compensated by reduc...

Abstract The paper addresses the limitations of Moth-Flame Optimization (MFO) algorithm, a meta-heuristic used to solve optimization problems. MFO which employs moths' transverse orientation navigation technique, has been generate solutions for such However, performance is dependent on flame production and spiral search components, mechanism could still be improved concerning diversity flames a...

The virtual machine (VM) allocation problem is one of the main issues in cloud data centers. This article proposes a new metaheuristic method to optimize joint task scheduling and VM placement (JTSVMP) center. JTSVMP problem, though composed two parts, namely placement, treated as be resolved by using optimization algorithms (MOAs). proposed co-optimization process aims schedule into which has ...
