Finite time stabilization of time-delay nonlinear systems with uncertainty and time-varying delay
In this paper, the problem of finite-time stability and finite-time stabilization for a specific class of dynamical systems with nonlinear functions in the presence time-varying delay and norm-bounded uncertainty terms is investigated. Nonlinear functions are considered to satisfy the Lipchitz conditions. At first, sufficient conditions to guarantee the finite-time stability for time-delay nonl...
متن کاملSimple reaction time as a function of time uncertainty.
An earlier study (3) showed that simple reaction time (RT) varies 'with S's uncertainty about time of stimulus occurrence. This time uncertainty is a function of both the mean duration of the time (foreperiod) between a warning signal and the stimulus and the variability within the series of foreperiods. Foreperiod variability adds uncertainty directly and mean foreperiod is important since S's...
متن کاملA Bayesian Sequential Sampling Model of Choice Reaction Time Incorporating Stimulus Onset/Duration Uncertainty
We propose a Bayesian sequential sampling model of choice reaction time (RT) which incorporates uncertainties about stimulus identity, onset, and duration. The model is the nowstandard random-walk/drift-diffusion model, with a thresholdbased response mechanism. The “substance” of the drift, however, is the posterior probability (belief) that a participant updates on a moment-to-moment basis dur...
متن کاملPredicting Fluid Intelligence by Components of Reaction Time Distributions from Simple Choice Reaction Time Tasks
Mean reaction times (RT) and the intra-subject variability of RT in simple RT tasks have been shown to predict higher-order cognitive abilities measured with psychometric intelligence tests. To further explore this relationship and to examine its generalizability to a sub-adult-aged sample, we administered different choice RT tasks and Cattell’s Culture Fair Intelligence Test (CFT 20-R) to n = ...
متن کاملEffect of Flashing Brake Lights on Drivers\' Brake Reaction Time and Release Gas Pedal Time
Objective: It is believed that drivers play a crucial role in accidents. Paying attention to brake lights, a driver may find out about danger and react. Rear-end collision accidents refer to the part of the accidents due to driver inattention or slow reaction. The aim of this study was to determine the effect of dynamic flashing brake lights (7 Hz) on drivers' brake reaction time using the driv...
