Time-Delay Interferometry [PDF]

open access: yesLiving Reviews in Relativity, 2014
Equal-arm detectors of gravitational radiation allow phase measurements many orders of magnitude below the intrinsic phase stability of the laser injecting light into their arms.

Time-delay polaritonics [PDF]

open access: yesCommunications Physics, 2020
AbstractNon-linearity and finite signal propagation speeds are omnipresent in nature, technologies, and real-world problems, where efficient ways of describing and predicting the effects of these elements are in high demand. Advances in engineering condensed matter systems, such as lattices of trapped condensates, have enabled studies on non-linear ...

Delay dependent stability of linear time-delay systems [PDF]

open access: yesTheoretical and Applied Mechanics, 2013
This paper deals with the problem of delay dependent stability for both ordinary and large-scale time-delay systems. Some necessary and sufficient conditions for delay-dependent asymptotic stability of continuous and discrete linear time-delay ...

Delay-dependent stability analysis for discrete-time systems with time varying state delay [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2011
The stability of discrete systems with time-varying delay is considered. Some sufficient delaydependent stability conditions are derived using an appropriate model transformation of the original system.

Ignition Delay Time Modeling in Wire-EDM

open access: yesJournal of Manufacturing and Materials Processing, 2023
This study presents a comprehensive investigation and modeling of the ignition delay time (td) in wire-EDM (WEDM). The research focuses on the influence of gap distance, discharge energy, and piece height on the stochastic distributions of td, providing ...

A survey of delay compensation and control based on continuum backstepping control algorithms for time-delay systems

open access: yes工程科学学报, 2022
In practical control systems, time delays inevitably occur when sensors need to measure and require the system’s data for decision making as well as when microcontrollers (or other devices) compute and implement control signal processes.

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 ...

Study on the Effective Region of Active Decoy Jamming to SAR Based on Time-delay Doppler-shift Method

open access: yesLeida xuebao, 2013
The active decoy jamming to SAR based on the Time-Delay Doppler-Shift (TDDS) method takes effect in certain region. Proper utilization of jamming ensuring decoy quality is based on the study of the effective region. After the mathematical analysis of the

Some applications of the Shapiro time delay [PDF]

open access: yesSerbian Astronomical Journal, 2023
Listening to echoes has long been a way to estimate distances, a technique whose backbone is the time delay. The gravitational field also creates a time delay, called Shapiro time delay, that helps us extract some information from the field and ...
