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 AND INHOMOGENEITIES

The Ninth Marcel Grossmann Meeting, 2002
Gravitational leasing plays an important role in studing the cosmological parameters, since propagation of light rays in curved spacetime is intrinsically connected to the structure of the universe. In particular,it depends also on the clumps of matter that it encounters on its way from the source to the observer...

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.

Errors in time delay measurements

pure and applied geophysics, 1971
Simple delay and sum of sensors in a seismic array is an effective method for noise suppression. However, unless we have precise steering delays, much of the signal energy is lost during the beam forming process too. We have investigated possible error sources in time delay measurements, using a computerized cross-correlation procedure.
