Dynamical Hysteresis without Static Hysteresis: Scaling Laws and Asymptotic Expansions [PDF]
SIAM Journal on Applied Mathematics, 1997 Summary: We study dynamical hysteresis in a simple class of nonlinear ordinary differential equations, namely first-order equations subject to sinusoidal forcing. The assumed nonlinearities are such that the area of the hysteresis loop vanishes as the forcing frequency tends to zero; in other words, there is no static hysteresis.

Scaling dynamic response and destructive metabolism in an immunosurveillant anti-tumor system modulated by different external periodic interventions. [PDF]
PLoS ONE, 2011 On the basis of two universal power-law scaling laws, i.e. the scaling dynamic hysteresis in physics and the allometric scaling metabolism in biosystem, we studied the dynamic response and the evolution of an immunosurveillant anti-tumor system subjected

Advances in Materials Science and Engineering, 2015 In order to accurately model the hysteresis and dynamic characteristics of piezoelectric stack actuators (PSAs), consider that a linear force and a hysteresis force will be generated by piezoelectric wafers under the voltage applied to a PSA, and the ...

DYNAMICS OF AN ENERGY HARVESTER WITH HYSTERESIS FRICTION
Vestnik of Samara University. Natural Science Series, 2023 A model of an energy harvester converter with hysteresis viscous friction is considered. The mechanical part of the energy harvester is made in the form of an inverted pendulum. The hysteresis is formalized within the framework of the Preisach model, which is a continuum analogue of a system of non-ideal relays connected in parallel.

HYSTERESIS AND VORTICES DYNAMICS IN A TURBULENT FLOW [PDF]
International Journal of Bifurcation and Chaos, 2009 Recent results about the slow dynamics present in a fully developed turbulent flow are reported. In a previous paper [de la Torre & Burguete, 2007] we showed that the mean velocity field in a turbulent flow bifurcates subcritically breaking some symmetries of the problem and becomes time-dependent because of equatorial vortices moving with a ...

Comparator with dynamic hysteresis
Electronics Letters, 1999 A comparator is presented which is based on the use of a time domain phenomenon called 'dynamic hysteresis'. This comparator features only one threshold and a short-time controllable noise immunity.
