Sentences with word «hysteresis»

In discussions of global change, the term tipping point has been used to describe a variety of phenomena, including the appearance of a positive feedback, reversible phase transitions, phase transitions with hysteresis effects, and bifurcations where the transition is smooth but the future path of the system depends on the noise at a critical point.

Researchers, led by Oak Ridge National Laboratory, clearly showed that both ferroelectric and non-ferroelectric materials could generate similar hysteresis loops in their electromechanical responses.

Or would melting of most of the cryosphere (given this input of just enough warming to cause that) ensure that we go into a long term extreme warming hysteresis event, leading to perhaps hydrogen sulfide outgassing and massive extinction?

Some other indicators point to a potential drag from a prolonged period of low headline inflation on the dynamics of wages and core prices, possibly reflecting hysteresis effects.

It has been improved in shift performance and reaction time by an optimized friction system and pistons with a lower hysteresis.

Little macro-models ain't an economy (btw, this is why we see hysteresis in unemployment figures).

«Wettability plays a key role in determining the equilibrium contact angles, contact angle hysteresis, and adhesion between a solid surface and liquid, as well as the retraction process of a liquid droplet impinged on the surface,» explained Doo Jin Lee, lead author, and a postdoctoral researcher in the Department of Materials and Engineering at Seoul National University.

The team measured hysteresis of the velocity of an active swarm in computer simulations and experiments on unicellular algae Euglena gracilis.

The team not only found full analogy of the active motion in a field to magnetic hysteresis but also managed to quantify the controllability of the swarm and identify the signatures of collective behavior of the active agents.

The bias - induced hysteresis loop that is observed in the electromechanical response has often been interpreted, and sometimes misinterpreted, as evidence of ferroelectricity.

Milton says that in addition to constant braking force, shape memory materials have a property called hysteresis, which in an ideal climbing rope «means the material will absorb a lot of energy, so that when it stretches, instead of bouncing to where you were before, you would fall, then it would retract slowly» instead of jerking you upward.
