Hysteresis

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.

Hysteresis

In economics, a situation or indicator that persists despite evidence that it should not. For example, the unemployment rate tends to remain high even after GDP growth has resumed, in part because business owners are afraid that growth will turn negative again even if they have no rational reason for believing so. One may think of hysteresis as an economy's collective memory. See also: Lagging indicator.

Weights of 4, 3, 2, and 1 were assigned to the bulk density, hysteresis loss, hardness, and tensile strength correspondingly, as ranked by their importance.
While there has been a significant amount of study on eddy current losses in magnets of PM synchronous machines, an in-depth study on hysteresis loss is not available.
Higher values of tan ([delta]) show higher hysteresis loss in UDPCs compared to FGPCs having any ascending/descending stacking sequence.
Apart from the magnitude, this is the reason why [P.sub.H] = 0.4 MW/kg was experimentally observed for the cobalt ferrite nanoparticles, despite the conventional prediction of no hysteresis loss under the experimental conditions.
Interestingly, tension set and hysteresis loss of FVP-filled and unfilled fluororubber vulcanizates do not change appreciably on incorporation of FVP.
Hysteresis loss was determined up to the second cycle by stretching dumb-bell test pieces to a strain level of 100% in the Zwick UTM.
Key statement: A rubber composition for a tire tread including 100 parts by weight of a diene-based rubber and 5 to 150 parts by weight of carbon black having a nitrogen adsorption specific area N2SA ([m.sup.2]/g) of 80 to 150 and satisfying a relationship between a TINT (%) and dibutyl phthalate absorption DBPA (ml/100 g) of TINT (%)>1.4 DBPA (ml/100 g) and capable of increasing the frictional force without impairing the hysteresis loss.
The hysteresis loss was calculated by the ratio of the area of the loop between the loading and unloading curves to the area under the stress-strain curve used.
Key statement: A rubber composition for an inner liner improving air retention property of a tire, lowering hysteresis loss and further preventing crack growth is provided.
Hysteresis loss at 100% elongation was measured at 25[degrees]C by subtracting the area under the force-retraction curve from the area under the force-deformation curve (up to 100% elongation).
Together with the high coupling efficiency of VP Si 363, this strongly reduced silica network leads to a very low hysteresis loss of the compound.
As the applied field is increased and approaches the value of the coercive field polarization reversal occurs giving rise to a large dielectric nonlinearity and hysteresis loss. At large fields the value of the spontaneous polarization tends to saturate.
