The presence of backlash in drivetrains is a major source of limitations as it introduces nonlinearities that reduce their efficiency in speed and position control. Existing models in backlash assume massless shaft, and use only elasticity and damping properties to describe the transmitted torque. This assumption makes them inaccurate since it does not account for the contribution of the body’s...

Black holes are the densest form of energy, and in the presence of compact dimensions black objects may take one of several forms including the black-hole and the black-string, the simplest relevant background being R3+1 × S. Recent understanding of the first order nature of the transition indicate a powerful “hysteresis” curve, where black objects may undergo fusion or fission during a tachyon...

Gear box dynamics is characterised by a periodically changing stiffness and a backlash which can lead to a loss of the contact between the teeth. Due to backlash, the gear system has piecewise linear stiffness characteristics and, in consequence, can vibrate regularly or chaoticaly depending on the system parameters and the initial conditions. We examine the possibility of a nonfeedback system ...

Hysteresis has been widely recognized in the soil water relationship. In this paper, a detailed review of hysteresis was performed in relation to its models. So far, different models have been suggested to describe hysteresis in the water retention curve (WRC) that could be categorized into two main groups: conceptual and empirical models. The models in the first group are based on the domain t...
