Telemanipulation with Time Delays

The International Journal of Robotics Research, 2004
In this paper we survey the development of the wave variable concept and examine wave-based teleoperation. We study the behavior of force reflecting systems under unknown but constant transmission delays, ranging from periods less than the human reaction time to several seconds.

TIME DELAY ESTIMATION

Journal of Time Series Analysis, 1988
AbstractThe problem considered is that of estimating the delays that arise when a waveform propagates across an array. Problems that arise in previous estimation techniques when the signal‐to‐noise ratio is low are reduced by introducing an improved weighting of frequencies into the formulae and by using finite parameter models to estimate this weight ...

The time-delay graph and the delayogram - new visualizations for time delay

IEEE Signal Processing Letters, 2005
For about 60 years, the spectrogram has been an excellent visualization tool for observing the acoustic and prosodic features of a speech signal. However, a visual tool has been lacking for information that is typically represented by the speech signal's phase.

Monitoring and Evaluation of Time Delay

International Journal of Human-Computer Interaction, 2005
In general, users act as if their behavior is controlled by a self-regulatory system (Carver & Scheier, 1998) during user-system interaction. The self-regulatory system is specified as a feedback control mechanism consisting of monitoring, evaluation, and action adjustment mechanisms. This article investigates whether perception processes take care

Time Delay in Random Scattering

SIAM Journal on Applied Mathematics, 1994
Summary: This work treats the time delay in scattering for the Schrödinger equation with a random potential. The time delay is related to the energy derivative of the phase shift. In the white noise limit, the phase shift and time delay satisfy a system of stochastic differential equations.

Stabilization by switching time-delay

Asymptotic Analysis, 2013
In this paper we consider some stabilization problems for the wave equation with switching time-delay. We prove exponential stability results for appropriate damping coefficients. The proof of the main results is based on D'Alembert formula, observability inequality and some energy estimates.

Time Delay

Remedial and Special Education, 1988
Students labeled mildly handicapped often fail to memorize and retain information such as math facts, sight words, and spellings when taught by traditional instructional procedures. Time delay, a nearly errorless instructional procedure, has been effective in teaching these behaviors to a variety of students.
