Crossword clues for hysteresis
The Collaborative International Dictionary
Hysteresis \Hys`te*re"sis\, n. [NL., fr. Gr. ? to be behind, to lag.] (Physics) 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.
Douglas Harper's Etymology Dictionary
1805, from Greek hysteresis "a coming short, a deficiency."
Wiktionary
n. 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°.
WordNet
n. 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
Wikipedia
Hysteresis is the time-based dependence of a system's output on present and past inputs. The dependence arises because the history affects the value of an internal state. To predict its future outputs, either its internal state or its history must be known. If a given input alternately increases and decreases, a typical mark of hysteresis is that the output forms a loop as in the figure.
Such loops may occur purely because of a dynamic lag between input and output. This effect disappears as the input changes more slowly. This effect meets the description of hysteresis given above, but is often referred to as rate-dependent hysteresis to distinguish it from hysteresis with a more durable memory effect.
Hysteresis occurs in ferromagnetic materials and ferroelectric materials, as well as in the deformation of some materials (such as rubber bands and shape-memory alloys) in response to a varying force. In natural systems hysteresis is often associated with irreversible thermodynamic change. Many artificial systems are designed to have hysteresis: for example, in thermostats and Schmitt triggers, the principle of hysteresis is applied to avoid unwanted frequent switching. Hysteresis has been identified in many other fields, including economics and biology.
In economics, hysteresis refers to the possibility that periods of high unemployment tend to increase the rate-of-unemployment-below-which-inflation-begins-to-accelerate, commonly referred to as the natural rate of unemployment or non-accelerating inflation rate of unemployment ( NAIRU). The term is based on the physical phenomenon of hysteresis in magnetic materials.
Usage examples of "hysteresis".
We assume a kind of inertia, or hysteresis effect, or special conservation law for time travel.
Normally, eddy current and hysteresis losses in the transformers would keep the station toast-warm.
When you apply those from the power source, you'll get eddy current heating inside the rock from hysteresis effects.
Gillette claims to have done slow-motion microphotography that shows hysteresis actually works, and, in an Esquire magazine article on this subject some years ago, a spokesman for Bic, one of Gillette's chief competitors, admitted his firm couldn't prove hysteresis didn't work.
