However, if the business has a small number of extensions, then it should instead use the more exact Engset calculation, which reflects the fact that extensions already in use will not make additional simultaneous calls.

To help determine the probability of congestion occurring, operators should use the Erlang formulas or the Engset calculation.

Engset's equation is similar to the Erlang-B formula ; however it contains one major difference: Erlang's equation assumes an infinite source of calls, yielding a Poisson arrival process, while Engset specifies a finite number of

There are several Erlang formulae, including Erlang B, Erlang C and the related Engset formula, based on different models of user behavior and system operation.

He developed the Engset formula ( 1915 ) before the breakthroughs of

( For a large user population, the Engset and the Erlang-B calculations give the same result.

Tore Olaus Engset ( May 8, 1865 in Stranda – October, 1943 in Oslo ) was a Norwegian mathematician and engineer who did pioneering work in the field of telephone traffic queuing theory.

Engset got a M. Sc.

* Arne Myskja: The Engset Report of 1915.

Sometimes it is necessary to roughly calculate the square inch area of the opening but the calculation can usually be made with sufficient accuracy that it won't affect the final computation.

This calculation results in an enthalpy rise which is somewhat high because it assumes a mass flow equally distributed over the plug cross section whereas in reality the mass velocity is expected to be smaller in the regions of higher temperatures.

Although the Af calculation is obvious by analogy with that for gravitational field and osmotic pressure, it is interesting to confirm it by a method which can be generalized to include related effects.

The mass scale used in Table 5-1 was derived on the assumption that the motion of the glowing trail is related to the momentum transfer to the trail by the meteorite, permitting the calculation of the mass if the velocity is known ( Cook and Whipple, 1958 ).

Presumably, if the reverse is the case and the good effect is more certain than the evil result that may be forthcoming, not only must the good and the evil be prudentially weighed and found proportionate, but also calculation of the probabilities and of the degree of certainty or uncertainty in the good or evil effect must be taken into account.

The 1 / 4 abacus, which is suited to decimal calculation, appeared circa 1930, and became widespread as the Japanese abandoned hexadecimal weight calculation which was still common in China.

The use of the soroban is still taught in Japanese primary schools as part of mathematics, primarily as an aid to faster mental calculation.

" For some people, a program is only an algorithm if it stops eventually ; for others, a program is only an algorithm if it stops before a given number of calculation steps.

The 1976 definition of the astronomical unit was incomplete, in particular because it does not specify the frame of reference in which time is to be measured, but proved practical for the calculation of ephemerides: a fuller definition that is consistent with general relativity was proposed, and " vigorous debate " ensued until in August 2012 the International Astronomical Union adopted the current definition of 1 astronomical unit = 149597870700 meters.

Whenever any result is sought by its aid, the question will then arise — By what course of calculation can these results be arrived at by the machine in the shortest time?

For normal calculation a number zero is often needed, here most notably when calculating the number of years in a period that spans the epoch ; the end years need only be subtracted from each other.

The correctness of Varro's calculation has not been proven scientifically but is still used worldwide.

This calculation also includes an allowance for light-time correction, and is therefore analogous to the concept of planetary aberration.

This equation is incorrect for the calculation of drag in most cases.

* Dry basis, an expression of a calculation in which the presence of water is ignored

Sacrifice bunts ( sacrifice hits since 1954 ), which would lower a batter's on-base percentage, are not included in the calculation for on-base percentage, as bunting is an offensive strategy – often dictated by the manager – the use of which does not necessarily reflect on the batter's ability and should not be used to penalize him.

In mathematics, a binary operation on a set is a calculation involving two elements of the set ( called operands ) and producing another element of the set ( more formally, an operation whose arity is two ).

Since the focus of his book was calculation, Bede gave instructions for computing the date of Easter and the related time of the Easter Full Moon, for calculating the motion of the Sun and Moon through the zodiac, and for many other calculations related to the calendar.

" It is a rational calculation where states fight for their interests ( whether they are economic, security related, or otherwise ) once normal discourse has broken down.

Hawking's calculation suggested that the radiation which black holes emit is not related in any way to the matter that they absorb.

: Administrator: the administrator typically deals with subscriptions and withdrawals by investors and the formal calculation of the value of the assets, and performs related back office functions.

The first mention of equal temperament related to Twelfth root of two in the West appeared in Simon Stevin's unfinished manuscript Van de Spiegheling der singconst ( ca 1605 ) published posthumously three hundred years later in 1884 ; however, due to insufficient accuracy of his calculation, many of the numbers he obtained were off by one or two units from the correct values.

RFC 3611 VoIP metrics reports are intended to support real time feedback related to QoS problems, the exchange of information between the endpoints for improved call quality calculation and a variety of other applications.

A related issue is interest rate disclosure: Many suppliers of microcredit quote their rates to clients using the flat calculation method, which significantly understates the true Annual Percentage Rate.

Two long papers published in 1840 — one on attractions and Clairaut's theorem, and the other on the variation of gravity at the surface of the earth — also demand notice, as do his mathematical memoirs on the critical values of sums of periodic series ( 1847 ) and on the numerical calculation of a class of definite integrals and infinite series ( 1850 ) and his discussion of a differential equation relating to the breaking of railway bridges ( 1849 ), research related to his evidence given to the Royal Commission on the Use of Iron in Railway structures after the Dee bridge disaster of 1847.

The Asian Development Bank is currently reviewing different options concerning the technical aspects related to the ACU calculation, including the nature of the basket, the choice of fixed weights vs. fixed units, the selection of currencies to be included in the basket, the choice of weights, the criteria for their periodical revision, and other aspects as well.

Even Thiele's assumption that the years of captivity were measured from Nisan does not reconcile Ezekiel's chronology for the captivity of Jeconiah with a 586 date, and the calculation given above that uses the customary Tishri-based years yields the summer of 587, consistent with all other texts in Ezekiel related to Jeconiah's captivity.

First, it conducts fundamental research in the basic mechanisms of perception, inference, calculation and communication related to integrative thinking in business.

The sum-product algorithm is related to the calculation of free energy in thermodynamics.

* The current value of a company's assets likely differ than the historical cost financial statements used in the NAV calculation ( and financial statement values and related principles of accounting vary from

The definition of " modified AGI " varies according to the purpose for which the related calculation is being used.

The generated Hermite polynomial is closely related to the Newton polynomial, in that both are derived from the calculation of divided differences.

This is related to an activity rate which is a similar calculation used in Activity-based costing.
