Stability of time-delay systems with impulsive control involving stabilizing delays

at - Automatisierungstechnik, 2020
This paper studies the stability of time-delay systems with impulsive control involving stabilizing delays. A Razumikhin-type inequality with delayed impulses is proposed, where the information of time delay existing in impulses is effectively fetched ...

The Spectrum of Delay Differential Equations with Large Delay

SIAM Journal on Mathematical Analysis, 2011
We show that the spectrum of linear delay differential equations with large delay splits into two different parts. One part, called the strong spectrum, converges to isolated points when the delay parameter tends to infinity. The other part, called the pseudocontinuous spectrum, accumulates near criticality and converges after rescaling to a set of ...

A generalized free-matrix-based integral inequality for stability analysis of time-varying delay systems

Applied Mathematics and Computation, 2019
This paper focuses on the delay-dependent stability problem of time-varying delay systems. A generalized free-matrix-based integral inequality (GFMBII) is presented.

Comparing Batch Delays and Customer Delays

Bell System Technical Journal, 1983
For a large class of queueing systems in which customers arrive in batches, Halfin (1983) showed that the delay distribution of the last customer in a batch to enter service coincides with the delay distribution of an arbitrary customer when the batch-size distribution is geometric. Halfin's result can be applied to study the performance of complicated

Exponential Stability of Delayed Systems with Average-Delay Impulses

SIAM Journal of Control and Optimization, 2020
In the paper, we investigate the exponential stability of nonlinear delayed systems with destabilizing and stabilizing delayed impulses, respectively.

Delayed puberty

Minerva Pediatrica, 2021
The onset of puberty may be late - in the latter part of the predicted normal range or truly delayed - beyond this range. The latest age to start is usually regarded as 13 years in girls and 14 years in boys. There may also be a delayed completion of puberty, 16 years in girls and 17 years in boys.

Delay calibration circuit for delay lines

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
A circuit for delay calibration of delay lines has been proposed. The proposed circuit is attractive for forwarded-clock links. Novel delay cell and a clock conditioning block reduce startup and false lock problems. The proposed wide-range calibration circuit has been realized in a 28nm CMOS process.

Precise Power Delay Profiling with Commodity Wi-Fi

IEEE Transactions on Mobile Computing, 2015
Power delay profiles characterize multipath channel features, which are widely used in motion- or localization-based applications. The performance of power delay profile obtained using commodity Wi-Fi devices is limited by two dominating factors.
