Research on the Dynamic Hysteresis Loop Model of the Residence Times Difference (RTD)-Fluxgate
Sensors, 2013 Based on the core hysteresis features, the RTD-fluxgate core, while working, is repeatedly saturated with excitation field. When the fluxgate simulates, the accurate characteristic model of the core may provide a precise simulation result.

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.

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.

Stochastic dynamics in quenched-in disorder and hysteresis [PDF]
Journal of Applied Physics, 1999 The conditions under which relaxation dynamics in the presence of quenched-in disorder lead to rate-independent hysteresis are discussed. The calculation of average hysteresis branches is reduced to the solution of the level-crossing problem for the stochastic field describing quenched-in disorder.
