In telecommunication and computer engineering , the queuing delay or queueing delay is the time a job waits in a Queue data structure queue until it can be executed. It is a key component of network delay . This term is most often used in reference to router computing router s. When Packet information technology packet s arrive at a router, they have to be processed and transmitted. A router can only process one packet at a time. If packets arrive faster than the router can process them such as in a burst transmission the router puts them into the queue also called the Buffer computer science buffer until it can get around to transmitting them. The maximum queuing delay is proportional to buffer size. The longer the line of packets waiting to be transmitted, the longer the average waiting time is and when the buffer fills the router must drop packets. When the transmission protocol uses the dropped packets symptom of filled buffers to regulate its transmit rate, as the Internet s TCP does, bandwidth is fairly shared at near theoretical capacity with minimal network congestion delays. Absent this feedback mechanism the delays become both unpredictable and rise sharply, a symptom also seen as freeways approach capacity metered onramps are the most effective solution there, just as TCP s self regulation is the most effective solution when the traffic is packets instead of cars . This result is both hard to model mathematically and quite counterintuitive to people who lack experience with mathematics or real networks. Failing to drop packets, choosing instead to buffer an ever increasing number of them, produces bufferbloat . In Kendall s notation , the M M 1 K queuing model, where K is the size of the buffer, may be used to analyze the queuing delay in a specific system.

Delay composition , also called delay charge or delay train , is a pyrotechnic composition , a sort of pyrotechnic initiator , a mixture of oxidizer and fuel that burns in a slow, constant rate that should not be significantly dependent on temperature and pressure. Delay compositions are used to introduce a cough delay into the firing train , e.g. to properly sequence firing of fireworks , to delay firing of ejection charge s in e.g. model rockets, or to introduce a few seconds of time between triggering a hand grenade and its explosion . Typical delay times range between several milliseconds and several seconds. A popular delay charge is a tube of pressed black powder . The mechanical assembly prevents the outright detonation of the charge. While delay compositions are principally similar to other fuel oxidizer compositions, larger grain sizes and less aggressively reacting chemicals are used. Many of the compositions generate little or no gas during burning. Typical materials used are Fuels silicon , boron , manganese , tungsten , antimony , antimony trisulfide , zirconium , zirconium &ndash nickel alloy, zinc , magnesium , etc. Oxidizers lead oxide s, iron oxide s, barium chromate , lead chromate , tin IV oxide , bismuth III oxide , barium sulfate for high temperature compositions , potassium perchlorate usually used in small amount together with other oxidizers , etc. Additives to cool down the flame and slow down the reaction can be employed inert materials or coolants like titanium dioxide , ground glass, chalk , sodium bicarbonate , etc. are common.

In telecommunication s, delay encoding is the encoding of binary numeral system binary data to form a two level Signalling telecommunication signal where a a 0 causes no change of signal level unless it is followed by another 0 in which case a transition to the other level takes place at the end of the first bit period and b a 1 causes a transition from one level to the other in the middle of the bit period. Propagation delayDelay encoding is used primarily for encoding radio signals because the frequency spectrum of the encoded signal contains less low frequency energy than a conventional non return to zero NRZ signal and less high frequency energy than a biphase signal. Delay encoding is an encoding using only half the bandwidth for biphase mark code biphase encoding but features all the advantages of biphase encoding To be rewritten It is guaranteed to have transitions every other bit, meaning that decoding systems can adjust their clock DC threshold continuously . One drawback is human readability e.g. on an oscilloscope . Delay encoding is also known as Miller encoding named after Armin Miller, its inventor . US Pat. 3,108,261 Some RFID cards, in particular EPC UHF Gen 2 RF cards, use a variant called Miller sub carrier coding . ref http rfidusa.com superstore pdf UHF System Overview.pdf UHF Gen 2 System Overview , p. 19.

The resultant binary subcarrier is itself either Amplitude shift keying ASK or Phase shift keying PSK modulated on another carrier.

Construction delays in residential and light construction are often the result of miscommunication between contractors, subcontractors, and property owners. These types of misunderstandings and unrealistic expectations are usually avoided through the use of detailed critical path method critical path schedules, which specify the work, and timetable to be used, but most importantly, the logical sequence of events which must occur for a project to be completed. Delays in construction projects are frequently expensive, since there is usually a construction loan involved which charges interest, management staff dedicated to the project whose costs are time dependent, and ongoing inflation in wage and material prices. However, in more complex projects, problems will arise that are not foreseen in the original contract, and so other legal construction forms are subsequently used, such as change orders, lien waivers, and addenda. In construction projects, as well in other projects where a schedule is being used to plan work, delays happen all the time. It s what is being delayed that determines if a project, or some other deadline such as a milestone, will be completed late. Before analyzing construction delays, a clear understanding of the general types of delays is necessary. There are four basic ways to categorize delays Critical or Non Critical Excusable or Non Excusable Concurrent or Non Concurrent Compensable or Non Compensable Before determining the impact of a delay on the project, one must determine whether the delay is critical or non critical. Additionally, all delays are either excusable or non excusable. Both excusable and non excusable delays can be defined as either concurrent or non concurrent. Delays can be further broken down into compensable or non compensable delays. Economic historian Robert E. Wright argues that construction delays are caused by bid gaming, change order artistry, asymmetric information , and post contractual market power . Until those ... more details
A delay line oscillator is a form of electronic Oscillation oscillator that uses a delay line as its principal timing element. The circuit is set to oscillate by Inverter logic gate inverting the output of the delay line and feeding that signal back to the input of the delay line with appropriate amplification. The simplest style of delay line oscillator, when properly designed, will oscillate with period exactly two times the delay period of the delay line. Additional outputs that are correlated in frequency with the main output but vary in phase can be derived by using additional taps from within the delay line The delay line may be realized with a physical delay line such as an LC circuit LC network or a transmission line . In contrast to a Phase shift oscillator in which LC components are lumped, the capacitances and inductances are distributed through the length of the delay line. A ring oscillator uses a delay line formed from the gate delay of a cascade of logic gate s. The timing of a circuit using a physical delay line is usually much more accurate. It is also easier to get such a circuit to oscillate in the desired Overtone mode . The delay line oscillator may be allowed to free run or it may be gated for use in Asynchronous circuit asynchronous logic . Since the optical cavity is a delay line, a laser can be regarded as a special case of the delay line oscillator.

A digital delay line is a discrete element in digital filter theory, which allows a signal to be delayed by a number of samples. If the delay is an integer multiple of samples digital delay lines are often implemented as circular buffer s. This means that integer delays can be computed very efficiently. The delay by one sample is notated math mathrm z 1 math and delays of math N math samples is notated as math mathrm z N math motivated by the role the z transform plays in describing digital filter structures. If a delay is not an integer of a sample additional filters are applied to account for the fraction of delay different from an integer. Hence delay lines with non integer delay are called fractional delay lines . ref Citation last Laakso first Timo I. author link last2 V lim ki first2 Vesa author2 link last3 Karjalainen first3 Matti last4 Laine first4 Unto K. publication date January 1996 date January 1996 title Splitting the unit delay tools for fractional delay filter design periodical IEEE Signal Processing Magazine edition volume 13 issue 1 pages 30 60 publication place place publisher id isbn doi 10.1109 79.482137 oclc url accessdate 2007 08 22 ref Digital delay lines are widely used building blocks in methods to simulate room acoustics , musical instruments and digital audio effects . ref Citation last Smith first Julius O. author link last2 Lee first2 Nelson author2 link publication date August 12 2007 date August 2007 title Computational Acoustic Modeling with Digital Delay url http ccrma.stanford.edu realsimple DelayDelay lines.html accessdate 2007 08 21 ref Digital waveguide synthesis shows how digital delay lines can be used as sound synthesis methods for various musical instruments such as string instruments and wind instruments .

For Small Scale channel modeling, the power delay profile of the channel is found by taking the spatial average baseband impulse respone of a multipath channel.that is h sub b sub t sup 2 sup over a local area. ref Rap91a ref References Reflist DEFAULTSORT Power Delay Profile Category Radio frequency propagation energy stub telecommunications stub ... more details
In telecommunication , receiver attack time delay is the time interval from a the instant a step rf Signalling telecommunication signal , at a level equal to the receiver threshold of sensitivity electronics sensitivity , is applied to the receiver input to b the instant the receiver output amplitude reaches 90 of its steady state value. If a squelch Telecommunication circuit circuit is operating, the receiver attack time Propagation delaydelay includes the time for the receiver to break squelch.
