gears are one of the most critical components in power transmission system of an automobile and also many rotating machinery. many studies have been conducted on optimum gear design. the main objective is to design different aluminium metal matrix composite spur gears before and after optimization. aluminium metal matrix material composites are preferred mostly due to their low density. also th...

low density polyethylene films incorporating different types of organically modified nanoclays were prepared. physical, surface morphology and mechanical properties of the films were analyzed by x-ray diffraction pattern, scanning electron microscopy and tensile strength (ts) and length increase until fracture point (e) parameters, respectively. colony counting method was used to investigate an...

In the present study, temporal behavior of entanglement between photonic binomial distributions and a two-level atom in a leaky cavity, in equilibrium with the environment at a temperature T, is studied. In this regard, the master equation is solved in the secular approximation for the density matrix, when the initial photonic distribution is binomial, while the atomic states obey the Boltzmann...
