تعريف to hysteresis في الإنجليزية الإنجليزية القاموس.

hysteretic

A property of a system such that an output value is not a strict function of the corresponding input, but also incorporates some lag, delay, or history dependence, and in particular when the response for a decrease in the input variable is different from the response for an increase. For example, a thermostat with a nominal setpoint of 75° might switch the controlled heat source on when the temperature drops below 74°, and off when it rises above 76°

The maximum difference in output for any given input (within the specified range) when the value is approached first with increasing, and then with decreasing, input signals Caused by energy absorption in the elements of the measuring instrument Usually expressed as a percentage of full-scale range

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

The failure of a property that has been changed by an external agent to return to its original value when the cause of the change is removed

The mechanical energy loss that always occurs under cyclical loading and unloading of a spring, proportional to the are between the loading and unloading load-deflection curves within the elastic range of a spring

The maximum difference between output readings for the same measured point, one point obtained while increasing from zero and the other while decreasing from full scale The points are taken on the same continuous cycle The deviation is expressed as a percent of full scale

Difference between the critical points on heating and cooling due to tendency of physical changes to lag behind temperature changes

on reversal of polarity

lag between an effect or response and the force that caused it (Physics); phenomenon in which a material's reaction to change is related its past reaction to the same type of stimulus

When an electrode system is returned to a solution, equilibrium is usually not immediate This phenomenon is often observed in electrodes that have been exposed to the other influences such as temperature, light, or polarization

the tendency of a magnetic substance to remain in a certain magnetic condition

In a valve with loose linkages, the air signal to the valve will have to change by an amount equal to the hysteresis before the valve stem will move Once the valve has begun to move in one direction it will continue to move if the air signal keeps moving in the same direction When the air signal reverses direction, the valve will not move until the air signal has changed in the new direction by an amount equal to the hysteresis

the irreversible magnetic flux density-versus-magnetic field strength (B-versus-H) behavior found for ferromagnetic and ferrimagnetic materials I

The property of a material wherein its condition at any instant depends upon its preceding condition; the failure of the magnetism to retrace its path as the field H varies

Describes the dependence of a physical system on its previous history For instance, the change in sediment concentration in a stream as a result of a storm

Used to characterize a lagging effect Firms may fail to enter markets that appear attractive, or firms that are once invested in a market may persist in operating at a loss The effect is characteristic of investments with high entry and exit costs along with high uncertainty

Non-uniqueness in the relationship between two variables as a parameter increases or decreases Also called deadband, or that portion of a system's response where a change in input does not produce a change in output

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) "

The temperature difference between a phase transformation upon heating and cooling In NiTi alloys, it is generally measured as the difference between Ap and Mp

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

As a parameter is increased, the behavior makes a sudden jump at a particular value of the parameter But as the parameter is then decreased, the jump back to the original behavior does not occur until a much lower value In the region between the two jumps, the system, is bistable

1 Any of several effects resembling a kind of internal friction, accompanied by the generation of heat within the substance affected

the lagging of an effect behind its cause; especially the phenomenon in which the magnetic induction of a ferromagnetic material lags behind the changing magnetic field

The phenomenon of a quartz resonator not to repeat the same frequency-temperature excursion over any cycle of environment temperature or slew rate Believed to be related to mechanical stress, doubly rotated crystal orientations offer improvements of greater than 10 to 100 over singly rotated cuts

Also called deadband That portion of a measuring system’s response where a change in input does not produce a change in output

The difference noted in a sensor's output as a response to first an increasing, and then a decreasing, input signal of the same value If Yi is the value of the output with an increasing input of value X, and Yd is the value of the output with decreasing input of value X, then the hysteresis can be defined as the maximum absolute value of the difference (Yi - Yd) for any value of X This is frequently expressed as a percentage of the sensor's full scale range and usually is included as a component of total sensor error

The ability of foam to maintain original support characteristics after flexing Hysteresis is the percent of 25% IFD loss measured as a compression tester returns to the normal (25% IFD) position after measuring 65% compression Lower hysteresis values, or less IFD loss are desirable Current research indicates that hysteresis values may provide a good indication of overall flexible foam durability Low hysteresis in conventional foam is equal to less IFD loss

Lagging of the magnetization of ferromagnetic material (see ferromagnetism), such as iron, behind variations of the magnetizing field. When such a material is placed in a coil of wire carrying an electric current, the magnetic field so created forces atoms in the material to align with the field. This increases the total magnetic field to a maximum when all the atoms are aligned, though the total field lags behind the magnetizing field. When the intensity of the magnetizing field is decreased to zero, some field remains in the material, and if the magnetizing field is reversed the total magnetization also reverses but again lags behind. The complete cycle, known as a hysteresis loop, dissipates energy in the form of heat as the magnetization is reversed

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

the irreversible magnetic flux density-versus-magnetic field strength (B-versus-H) behavior found for ferromagnetic and ferrimagnetic materials; a closed B-H loop is formed upon field reversal

The maximum difference in output, at any pressure value within the specified range, when the value is approached first with increasing and then decreasing pressure
