Measurement of reverberation time using Time Delay Spectrometry (TDS)

open access: yesArchives of Acoustics, 2014
In the series of papers printed in the Journal of Audio Engineering Society in late sixties and early seventies, Richard C. Heyser introduced a revolutionary measurements technique which he named Time Delay Spectrometry (TDS) [1-6].

Time-Delay Interferometry and Clock-Noise Calibration

open access: yes, 2018
The Laser Interferometer Space Antenna is a joint ESA-NASA space-mission to detect and study mHz cosmic gravitational waves. The trajectories followed by its three spacecraft result in unequal- and time-varying arms, requiring use of the Time-Delay ...

Finite Time Stability of 2D Fractional Hyperbolic System with Time Delay

open access: yesJournal of Function Spaces, 2022
In this work, a class of two-dimensional fractional hyperbolic differential linear system (2D-FHDLS) with time delay is investigated. By using generalized Gronwall’s inequality, sufficient conditions for the finite time stability (FTS) of two-dimensional

Time-delay compensator design

open access: yes2017 11th Asian Control Conference (ASCC), 2017
The problem of designing linear time-invariant stabilizing time-delay compensators for a class of linear timeinvariant retarded time-delay systems is considered. To solve this problem, an approach, based on the continuous pole placement algorithm, is proposed. A design example is also presented to demonstrate the proposed approach.

The Effect of Screen Time on Delays in Language and Speech Developmental Children: Meta-Analysis

open access: yesJurnal Ilmu dan Teknologi Kesehatan
Language is a communication tool that humans often use. In the current globalisation era, finding and exchanging information takes effort. This is of course because of progress in the era of globalization, everything has become more accessible and easier

A Cumulative-signals-based Method for Time Delay Estimation

open access: yesMeasurement Science Review, 2019
An original method for time delay estimation is presented. It is based on changing input signals into cumulative ones, followed by determination of inflection points of cumulative curves, and estimation of time delay as time difference of these points ...

Evidence that conflict regarding size of haemodynamic response to interventricular delay optimization of cardiac resynchronization therapy may arise from differences in how atrioventricular delay is kept constant. [PDF]

open access: yes, 2014
Aims: Whether adjusting interventricular (VV) delay changes haemodynamic efficacy of cardiac resynchronization therapy (CRT) is controversial, with conflicting results.

Dimensional reduction of nonlinear time delay systems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
Whenever there is a time delay in a dynamical system, the study of stability becomes an infinite-dimensional problem. The centre manifold theorem, together with the classical Hopf bifurcation, is the most valuable approach for simplifying the infinite ...

Particle impact location detector [PDF]

open access: yes, 1974
Detector includes delay lines connected to each detector surface strip. When several particles strike different strips simultaneously, pulses generated by each strip are time delayed by certain intervals. Delay time for each strip is known.
