Fine Y3Fe5O12 (YIG) powder with self-heat generation ability in an AC magnetic field was prepared by a modified co-precipitation method and calcined at 600–1100 °C. Using this method, single phase of the YIG ferrite structure obtained low calcination temperature. The heat synthesis sample particle diameter ?120 nm significantly improved. correlation between hysteresis loss not confirmed for sam...

PURPOSE To develop a method for evaluating viscosity and elasticity of the cornea and to examine the effect that both properties have on hysteresis. METHODS A three-component spring and dashpot model was created in Simulink in Matlab to represent the purely elastic and viscoelastic behavior of the cornea during a measurement using device called an ocular response analyzer (ORA). Values for el...

This paper addresses handover decision instability which impacts negatively on both user perception and network performances. To this aim, a new technique called The HandOver Decision STAbility Technique (HODSTAT) is proposed for horizontal handover in Wireless Local Area Networks (WLAN) based on IEEE 802.11standard. HODSTAT is based on a hysteresis margin analysis that, combined with a utility...

Prandtl–Ishlinskii (PI) hysteresis models have been used widely in magnetic and smart material-based systems. A generalized PI model, consisting of a weighted superposition of generalized play operators, is capable of characterizing saturated and asymmetric hysteresis. The fidelity of the model hinges on accurate representation of the envelope functions, play operator radii, and corresponding w...

Smart materials display coupling between electrical, magnetic, thermal and elastic behavior. Hence these materials have inherent sensing and actuation capacities. However, the hysteresis inherent to smart materials presents a challenge in control of these actuators/sensors. Inverse compensation is a fundamental approach to cope with hysteresis, where one aims to cancel out the hysteresis effect...
