Definitions for "Hysteresis"
A lagging or retardation of the effect, when the forces acting upon a body are changed, as if from velocity or internal friction; a temporary resistance to change from a condition previously induced, observed in magnetism, thermoelectricity, etc., on reversal of polarity.
the lagging of strain behind stress during deformation.(sc) This term is generally associated with the semiconductor industry. This term is generally associated with the rubber industry.
The phenomenon in magnetic materials where the flux density (B) lags the magnetising force (H).
The mechanical energy loss that always occurs under cyclic loading and unloading of a spring, proportional to the area between the loading and unloading load-deflection curves within the elastic range of a spring.
Shift in calibration of transducer when on "return" from actuation load.
The ability of FPF to maintain original characteristics after flexing. Lower hysteresis values, or less IFD loss are desirable. Indentation Force Deflection (IFD) - IFD is generally measured as the force (in pounds) required to compress a 50-square-inch circular indentor foot into a four inch thick sample, typically 15 inches square or larger, to a stated percentage of the sample's initial height. Common IFD values are generated at 25 and 65 percent of initial height. Note: Previously called "ILD (Indentation Load Deflection)."
Hysteresis is any situation in which the value of one variable depends upon whether the other has been increasing or decreasing.
For a system with an analog input and digital output, the output value is dependent on both the input value and output state such that there is an input range over which the output can be high or low.
The difference in the output state of a mechanical system with respect to input history; a component of bi-directional repeatability. When the Dojen is loaded in one direction, the needle bearings, grease and steel components are deflected. When the load is removed, the components must first relax, as with any spring, before motion is reversed.
The energy lost in a complete cycle of deformation and retraction.
Refers to the percent energy lost per cycle of deformation or 100% minus the resilience percent. Hysteresis is the result of inter-molecular friction and is manifested by conversion of mechanical energy to heat. See viscoelastic effect.
Actions and reactions: not all energy applied to a tyre becomes totally absorbed by the latter, there is always an energy loss, that transforms into "heat". When dealing with an elastic material like rubber.
A bias resulting from the reversal of direction.
Hysteresis is based on crystalline polarization effects and molecular friction and occurs when reversing direction. Hysteresis is not to be confused with backlash.
The delay between the switching action of a control and the effect. Can be enforced to prevent rapid short-term reversals in the control's state.
property of a measuring instrument whereby its response to a given stimulus depends of the sequence of preceding stimuli. For example dependence of reading on whether pressure is rising or falling.
the ability for two pieces of paper to have different moisture content at equilibrium conditions based on the previous relative humidity exposure
the occurrence of a different value in the potential difference after the concentration of the test solution has been changed and then restored to its original value. This systematic error is generally in the direction of the concentration of the previous solution. Thus, if the electrodes are washed with water between each sample measurement, successive readings of the same solution can be expected to become progressively lower for cations and higher for anions.
The positioning error between forward scan and backward scan. A closed-loop control is an ideal solution for the problem. Capacitance sensors are normally used in nPoint's nanopositioners to provide feedback signals. It is a non-contact displacement measurement technique, which is hysteresis free.
A characteristic of materials, sensors and sometimes instruments to make their behavior dependent on the immediate history to which they have been subjected. Typically the final settling point is different when approached from above to when it is approached from below
Hysteresis is a measurement of an electrical component's change in performance as a result of continued operation. When a component is operated for the first time (for example, a temperature sensor reading temperature from cool to warm), it will follow a particular curve. When you then move the system in the opposite direction (say, change the temperature back to cool), the component will follow a similar curve back to its original state, but slightly displaced from the original curve, like so: More details
(1) Physiology. A delay of effect. (2) Devices. A programmable feature in some demand pacemakers which allows programming of a hysteresis escape rate lower than the programmed base rate. The pulse generator will be inhibited if the intrinsic rate equals or exceeds the hysteresis escape rate; should the intrinsic rate fall below the hysteresis escape rate, there is one cycle of pacing at the escape rate followed by pacing at the programmed base rate until the pacemaker is again inhibited by a sensed event. Hysteresis is accomplished by a timing mechanism which prolongs the pacing interval following a sensed beat.
A deviation from setpoint caused by friction and parts clearance. Impulse Line - See control line.

The effect on the stage-discharge relation at a gauging station subject to variable water surface slope where, for the same gauge height, the discharge on a rising stage differs from that on a falling stage.
The maximum difference between two set points typically associated with control.
The difference between the step positions when moving CW and the step positions when moving CCW. A step motor may stop slightly short of the true position, thus producing a slight difference in position CW to CCW.
Temperature sensitivity between turn on and turn off points on on-off control. Prevents chattering.
