CB-MLE: Time-Delay Estimation Method for SISO Delay Systems

IEEE Access, 2018
A time-delay estimation method is proposed for single-input single-output (SISO) delay systems. A copula is constructed from uniformly sampled input-output data to build the relationship between the input and output of the system.

Time development of a wave packet and the time delay [PDF]

, 1997
A one-dimensional scattering problem off a $\delta$-shaped potential is solved analytically and the time development of a wave packet is derived from the time-dependent Schr\"odinger equation.

Time Delay Signature Extraction of Optical Time-Delay Chaos Systems From Short and Noisy Time Series

IEEE Photonics Journal
The optical chaos communication (OCC) can provide physical layer security for high-speed data transmission. In these OCC systems, the time delay signature (TDS) serves as a crucial encryption key.

Fully Data‐Driven Time‐Delay Interferometry with Time‐Varying Delays

Annalen der Physik, 2023
AbstractRaw space‐based gravitational‐wave data like laser interferometer space antenna's (LISA) phase measurements are dominated by laser frequency noise. The standard technique to make this data usable for gravitational‐wave detection is time‐delay interferometry (TDI), which cancels laser noise terms by forming suitable combinations of delayed ...

Survey of time preference, delay discounting models [PDF]

Judgment and Decision Making, 2013
The paper surveys over twenty models of delay discounting (also known as temporal discounting, time preference, time discounting), that psychologists and economists have put forward to explain the way people actually trade off time and money.

Time-Delay Estimation Improves Active Disturbance Rejection Control for Time-Delay Nonlinear Systems

Machines
Lately, active disturbance rejection control (ADRC), a model-independent controller, has become popular for combating various forms of uncertain disturbances incurred in industrial applications.

Solid state variable time delay [PDF]

, 1970
Variable time delay line does not require use of a magnetic field to control a time delay, and can both amplify and delay a signal. Device is inexpensive and space saving, it does not require mecanically moving components, eliminating detrimental ...

On the time delay in binary systems [PDF]

, 2005
The aim of this paper is to study the time delay on electromagnetic signals propagating across a binary stellar system. We focus on the antisymmetric gravitomagnetic contribution due to the angular momentum of one of the stars of the pair.

Delay Estimation from noisy time series

, 1997
We propose here a method to estimate a delay from a time series taking advantage of analysis of random walks with delay. This method is applicable to a time series coming out of a system which is or can be approximated as a linear feedback system with ...
