This paper addresses the problem of the fractional sliding mode control (FSMC) for a MEMS optical switch. The proposed scheme utilizes a fractional sliding surface to describe dynamic behavior of the system in the sliding mode stage. After a comparison with the classical integer-order counterpart, it is seen that the control system with the proposed sliding surface displays better transient per...

We present a mathematical model describing the electro-mechanical coupling and the mechanical activity of the myofibres of the cardiac muscle and we perform the simulations for the partial differential equations describing the dynamical displacement of a onedimensional body with the resulting constitutive law. Prescribed boundary conditions describing the cardiac valves mechanisms and the arter...

Even under normal operating conditions, power devices are subject to temperature changes that generate high level of stress repeatedly causes mechanical breakdown. In this context thermomechanical simulations are necessary to predict life time and guarantee a longer lifespan. This paper aims to modeling electro-thermo-mechanical behavior of a vertical power transistor for predicting the influen...
