This paper investigates the reliable stabilization problem for a class of nonlinear networked control systems (NCSs) under variable sampling with variant state and network delays. An equivalent continuous-time uncertain fuzzy system with both state and input time varying delays, subject to possible actuator faults, is derived based on the Takagi-Sugeno (T-S) model and the input delay method. In...

Recurrent fuzzy neural networks (FNNs) have been widely applied to dynamic system processing problems. However, most recurrent FNNs focus on the use of type-1 fuzzy sets. This paper proposes a Mamdani-type recurrent interval type-2 FNN (M-RIT2FNN) that uses interval type-2 fuzzy sets in both rule antecedent and consequent parts. The reason for using interval type-2 fuzzy sets is to increase net...

The present investigation deals with study of thermoelastic damping and frequency shift of Kirchhoff plate resonators by using generalized thermoelasticity theory of dual-phase-lag model. The basic equations of motion and heat conduction equation are written with the help of Kirchhoff-Love plate theory and dual phase lag model. The analytical expressions for thermoelastic damping and frequency ...

The fixed-lag smoothing problem with a partial lag is the problem in which the presence of the smoothing lag is allowed only in a part of estimation channels. This paper studies the effect of a partial smoothing lag on the achievable H ∞ performance in the continuous-time case. In particular, the limit of the achievable performance is established and the saturation of the achievable performance...

The time-lag method, using a gas permeation experiment, is currently the most popular method for determining the membrane properties: diffusivity coefcient and permeability coefcient, and from which the solubility coefcient can be calculated. In this investigation, the impact of systematic, random (noise), resolution and extrapolation errors associated with gas permeatio...

Sleep loss and circadian disruption-a state of misalignment between physiological functions and imposed sleep/wake behavior-supposedly play central roles in the etiology of shift work-related pathologies [1-4]. Circadian entrainment is, however, highly individual [5], resulting in different chronotypes [6, 7]. Chronotype in turn modulates the effects of working times: compared to late chronotyp...

Although we expect managers to use the capabilities of business analytics systems to search for solutions and improve firm performance, we do not have a good understanding of the factors that motivate managers to undertake such search. Drawing on attribution and control theories, we propose a theory that explicates the performance conditions under which managers undertake search activities. Spe...

Travel fatigue is associated with long haul flights, and jet lag is experienced when flights entail transmeridian travel. Symptoms are linked with disturbance of the body’s circadian rhythms. Exercise performance may be affected until the body clock is adjusted to the new time zone. Methods of speeding up the adjustment include pharmacological and behavioral methods. Emphasis is placed on behav...

Night shift work and rapid transmeridian travel result in a misalignment between circadian rhythms and the new times for sleep, wake, and work, which has health and safety implications for both the individual involved and the general public. Entrainment to the new sleep/wake schedule requires circadian rhythms to be phase-shifted, but this is often slow or impeded. The authors show superimposed...
