IYER, VIJAY R. A Simulation Study of Wavelength Assignment and Reservation Policies with Signaling Delays. (Under the direction of Professor George N. Rouskas). This thesis studies the effect of non-negligible signaling delays on the performance of wavelength-assignment heuristics, wavelength reservation schemes, routing schemes, holding time (average being 1/μ) of the lightpaths and traffic lo...

a memory control for t-s fuzzy discrete-time systems with sto- chastic input delay is proposed in this paper. dierent from the common assumptions on the time delay in the existing literatures, it is assumed in this paper that the delays vary randomly and satisfy some probabilistic dis- tribution. a new state space model of the discrete-time t-s fuzzy system is derived by introducing some stocha...

In two experiments, the pattern of persistence of negative priming effects across delay intervals of 500 and 2,500 msec was assessed using a within-subjects, random sequencing of delays. Neill and Valdes (1992; Neill, Valdes, Terry, & Gorfein, 1992) have argued that a within-subject experimental design is required for decay of negative priming to be seen, in contrast to results reported elsewhe...

Bluetooth is currently emerging as one of the most promising personal wireless network technologies. The automation industry is also showing interest in using Bluetooth for more industrial applications. However, problems with unreliable links and time delays must be explicitly addressed in any wireless control application. This paper discusses two specific problems that may occur when using Blu...

The estimation problem is investigated for a class of stochastic nonlinear systems with distributed time-varying delays and missing measurements. The considered distributed time-varying delays, stochastic nonlinearities, and missing measurements are modeled in random ways governed by Bernoulli stochastic variables. The discussed nonlinearities are expressed by the statistical means. By using th...

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...

In this paper, we study the dynamics of COVID-19 in UAE with an extended SEIR epidemic model vaccination, time-delays, and random noise. The stationary ergodic distribution positive solutions is examined, which solution fluctuates around equilibrium deterministic case, causing disease to persist stochastically. It possible attain infection-free status (extinction) some situations, diseases die ...

Dynamical networks with time delays can pose a considerable challenge for mathematical analysis. Here, we extend the approach of generalized modeling to investigate the stability of large networks of delay-coupled delay oscillators. When the local dynamical stability of the network is plotted as a function of the two delays then a pattern of tongues is revealed. Exploiting a link between struct...

We here compare the limit performance asynchronous DS-CDMA systems based on different set of spreading sequences, namely chaos-based, ideal random, Gold codes and maximum-length codes. To do so we consider the Shannon capacity associated to each of those systems that is itself a random variable depending on the relative delays and phases between different users. The statistical features of such...

Like electroencephalographic (EEG) activity during reaction time tasks, EEG activity during tasks without overt responses may also consist of two components: stimulus-locked and -unlocked components. The extraction of such stimulus-unlocked components has been difficult owing to the unknown delays. Here, we propose a novel method to extract both of the two components from single-channel EEG epo...
