the aim of this project is to fabricated an aluminium-copper bimetal through the fusion method and examine its performance. an aluminium-copper-aluminium bimetal was built by the laser cladding method. the laser power as well as the annealing time effects on its interfacial properties of the bonding’s formed through the laser cladding were investigated. to fabricate the multilayer bimetal, the ...

introduction: management is one of the most important factors for life, development, growth or death of any organizations including hospitals. the power is of one of the main concepts that by focusing on the fundamental and theoretical efforts considered as an important factor at all levels of management and human resources. managers who know the sources of power and are using them, have more e...

Core stability (CS) is a popular term that has evolved into a fundamental concept the much rehabilitation, performance training and preventative programs. The purpose of this study is considering the relationship between CS power and endurance with performance of adolescence athletes. 12 male swimmers participated in the study. McGill Protocol, the core stability power, MBESTT and 30/60 sit-up ...

Active power decoupling (APD) method has been studied to enhance the lifetime of residential photovoltaic (PV) generation systems. In single-phase inverter, DC voltage a ripple due propagation 2nd pulsation from fundamental and current. The APD suppresses by compensating for pulsation. However, grid contains harmonic components these harmonics, which can propagate side. Conventional control com...

We present architectures, circuits, and algorithms for dynamic 3-D lensing focusing of electromagnetic power in radiative near- far-field regions by arrays that can be arbitrary nonuniform. They benefit applications such as wireless transfer at a distance (WPT-AD), volumetric sensing imaging, high-throughput communications, optical phased arrays. Theoretical limits on system performance are cal...

since the end of the cold war era in a u-turn in her foreign policy india has changed from a fighter with imperialism to a close ally of the west. beside political factors, economic factors and above all waves of globalization were among the most influential causes of this u-turn. analysts hold different attitudes towards why such a change happened and whether it was in the interest of india in...
