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 ...

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

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.

Batch Delays Versus Customer Delays

Bell System Technical Journal, 1983
For a large class of contention schemes with messages transmitted by subdividing them into packets, we show that the delay distribution of a message is the same as that for an individual packet. We conclude this from analyzing queueing systems with batch arrivals, where batch sizes have a geometric distribution and the queue discipline is indifferent ...

Delays and more delays

2015
In the wake of NASA’s announcement that Lt. Col. John H. Glenn, Jr. would be the first American to orbit the Earth, with a tentative launch date set for 20 December 1961, an excited expectation began to ripple across the United States, with people eager to follow the progress of this historic event.

Delay and delay-derivative dependent stability analysis for linear time delay systems with a cyclical delay

ISA Transactions
This study investigates the stability analysis of linear systems with cyclical delays, where the delay interval is partitioned into subintervals that exhibit alternating cycles of monotonic increase and decrease. The Lyapunov-Krasovskii functionals (LKFs) are constructed by integrating two-loop functional frameworks based on delay product terms, which ...

On Delay of the Delayed Choice Experiment

Chinese Physics Letters, 2015
Following a suggestion by Wheeler, several delayed choice experiments have been performed. However, in those experiments one fact has always been ignored: that due to the fact that the single photon is nonlocal in time, the outcome will change if one changes the time to switch the experimental configuration within the photon's wavepacket.

Dynamics of the Logistic Equation with Delay and Delay Control

International Journal of Bifurcation and Chaos, 2014
Asymptotic methods investigate the dynamic properties of the logistic equation with delay and delay control. The possibility to effectively control the characteristics of the relaxation cycle has been illustrated. We introduce a new method of studying the dynamics, provided that the ratio of the delayed control is large enough.

Trainable Delays in Time Delay Neural Networks for Learning Delayed Dynamics

IEEE Transactions on Neural Networks and Learning Systems
In this article, the connection between time delay systems and time delay neural networks (TDNNs) is presented from a continuous-time perspective. TDNNs are utilized to learn the nonlinear dynamics of time delay systems from trajectory data. The concept of TDNN with trainable delay (TrTDNN) is established, and training algorithms are constructed for ...
