High-speed maglev train is considered an ideal vehicle in the 21st Century, as an important part of the train, the travel mechanism bears and delivers a variety of vertical and horizontal alternating load in operation, it affects the operation safety of the train directly, so key components of the travel mechanism should under fatigue strength test by fatigue test machine.The paper proposed a v...

Magnetic levitation (Maglev) systems are widely employed in the industry especially mechatronics for precise positioning and suspension. They inherently unstable having nonlinear models with uncertain parameters exposed to external disturbances. Therefore, high-performance robust control designs recommended these systems. An Adaptive Variable Structure Controller based on barrier function (AVSC...

organization theory is a discipline on the boundary between economics of organizations, sociology of organizations, management and political science. she is interested in organizations, both commercial and non-commercial, in all their diversity (company, hospital, union, organization, administration, conventions). it analyzes their functioning, structure and development for the purpose of bette...

in this article, modeling and optimization of power consumption of two–stage compressed airsystem has been investigated. to do so, the two – stage compressed air cycle with intercooler offajr petroleum company was considered. this cycle includes two centrifugal compressors, ashell, and a tube intercooler. for modeling of power consumption, actual compressors isentropicefficiencies and intercool...
