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

Synchronization of Time Delay Neutrosophic Stochastic System [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
This paper examines the asymptotic mean square solidness of a turbulent synchronization to time de lay neutrosophic stochastic framework. The Lyapunov solidness hypothesis is utilized to plan a neutrosophic-based stochastic framework with time postpone ...

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.

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 ...

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.

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.
