Time delay estimation [PDF]

open access: yesIEEE Transactions on Acoustics, Speech, and Signal Processing, 1981
This paper presents a tutorial review of work in time delay estimation. A derivation of the ML estimator for time delay is presented together with an interpretation of that estimator as a special member of a class of generalized cross correlators. The performance of the estimator is given for both high and low signal to noise ratio cases.

Caching with Time Windows and Delays

open access: yesSIAM Journal on Computing, 2022
We consider two generalizations of the classical weighted paging problem that incorporate the notion of delayed service of page requests. The first is the (weighted) Paging with Time Windows (PageTW) problem, which is like the classical weighted paging problem except that each page request only needs to be served before a given deadline.

Time-Delay and Fractional Derivatives

open access: yesAdvances in Difference Equations, 2011
This paper proposes the calculation of fractional algorithms based on time-delay systems. The study starts by analyzing the memory properties of fractional operators and their relation with time delay.

Photoionization Time Delays [PDF]

open access: yes, 2015
The material presented in this chapter is based on important advances realized in “attophysics” which make feasible to follow the motion of electrons in atoms and molecules with attosecond-level time resolution. In this context, time-delays have been recently determined in the process of photoionization by extreme-ultra-violet (XUV) pulses and the ...

Synchronization of Time Delayed Systems by Common Delay Time Modulations [PDF]

open access: yesISRN Applied Mathematics, 2011
We investigate the synchronization phenomenon between two identical time delayed systems with the common time delay, modulated by a chaotic or random signal. The phenomenon is verified by the conditional Lyapunov exponent. The relation between the present form of synchronization with generalized one is also discussed.

Practical stability of time‐varying positive systems with time delay

open access: yesIET Control Theory & Applications, 2021
This paper considers the problem of practical stability for time‐varying positive systems with time delay. For both non‐linear time‐varying positive systems and linear time‐varying positive (LTVP) systems with time delay, sufficient conditions on ...

Numerical Simulation on Selection of Optimal Delay Time for Precise Delay Blasting

open access: yesShock and Vibration, 2021
In the traditional presplitting blasting, the presplit holes are generally uniformly initiated, which causes local damage to the retained rock mass while forming the damping ditch.
