Joint importance of multistate systems [PDF]
Computers & Industrial Engineering, 2005 Importance measures in reliability engineering are used to identify weak areas of a system and signify the roles of components in either causing or contributing to proper functioning of the system. Traditional importance measures for multistate systems mainly concern reliability importance of an individual component and seldom consider the utility ...

Robustness of Delayed Multistable Systems [PDF]
, 2019 In this chapter sufficient conditions for input-to-state stability (ISS) of delayed systems are presented using Lyapunov-Razumikhin functions. It is shown that ISS multistable systems are robust with respect to delays in the feedback path. First, the approach is illustrated by establishing the ISS property for the model of a non-linear pendulum, then ...

Time-dependent control of ultracold atoms and Bose-Einstein condensates in magnetic traps [PDF]
, 1997 With radiofrequency fields one can control ultracold atoms in magnetic traps. These fields couple the atomic spin states, and are used in evaporative cooling which can lead to Bose-Einstein condensation in the atom cloud.

Epilepsy as a manifestation of a multistate network of oscillatory systems
Neurobiology of Disease, 2019 The human brain, largely accepted as the most complex biological system known, is still far from being understood in its parts or as a whole. More specifically, biological mechanisms of epileptic states and state transitions are not well understood. Here,
