We work with a class of scalar extended theory gravity that can drive the present cosmic acceleration as well accommodate mild variation fine structure constant $\alpha$. The motivation comes from vintage developed by Bekenstein, Sandvik, Barrow and Magueijo. $\alpha$ is introduced real field interacting charged matter. execute cosmological reconstruction based on parametrization matter density...

in this paper, we are going to study the g-natural metrics on the tangent bundle of finslermanifolds. we concentrate on the complex and kählerian and hermitian structures associated with finslermanifolds via g-natural metrics. we prove that the almost complex structure induced by this metric is acomplex structure on tangent bundle if and only if the finsler metric is of scalar flag curvature. t...

This paper includes modeling and simulation of 180 MW units of pumped storage power plant with Variable speed machines. In this method, voltage source inverters are used instead of traditional cyclo-converters. This paper aims to control the voltage source inverters and maintain DC voltage at a constant value. AC/ DC/ AC converter is used in system configuration structure in order to control an...
