A delay-dependent H∞ variable structure control is presented for uncertain singular time-delay systems. System with mismatched norm-bounded uncertainties and mismatched norm-bounded external disturbances are considered. In terms of linear matrix inequalities (LMIs), we give a delay-dependent sufficient condition for the existence of switching surfaces, on which sliding mode dynamics is regular,...

The dual-process component of Terror Management Theory (TMT) proposes that different types of threats lead to increases in death-thought accessibility (DTA) after different delay intervals. Experimental studies of terror management threats' effect on DTA were collected and coded for their use of explicitly death-related (vs. not explicitly death-related) threats, and for their use of delay and ...

A scheduling problem that includes different hardware delays experienced by the secondary users (SUs) while switching to different frequency bands in a centralized cognitive radio network (CRN) is formulated. A polynomial-time suboptimal algorithm is proposed to reduce the scheduling problem. The impact of varying switching delay, number offer quencies, and number of SUs is evaluated. The simul...

We address the problem of estimating the average switching activity of combinational circuits under random input sequences. Switching activity is strongly affected by gate delays, and for this reason we use a variable delay model in estimating switching activity. Unlike most probabilistic methods that estimate switching activity, our method takes into account correlation caused at internal gate...

Bitstream switching is an effective way to deal with bandwidth variation in transmitting multimedia over time−varying channels. A number of bitstream switching mechanisms have been proposed to reduce the potential error drift introduced by bitstream switching, often without explicitly taking into account the impact of the switching on the bandwidth and delay requirements in their performance an...

Weconsider the task assignment problem to heterogeneous parallel serverswith switching delay, where servers can be switched off to save energy. However, switching a server back on involves a constant server-specific delay. We will use one step of policy iteration from a starting policy such as Bernoulli splitting, in order to derive efficient task assignment (dispatching) policies that minimize...

This paper mainly tends to utilize Razumikhin-type theorems to investigate p-th moment stability for a class of stochastic switching nonlinear systems with delay. Based on the Lyapunov-Razumikhin methods, some sufficient conditions are derived to check the stability of stochastic switching nonlinear systems with delay. One numerical example is provided to demonstrate the effectiveness of the re...
