About a quarter of Hardy's poems carry an appended date line, usually the year of completion, but sometimes inclusive years ( `` 1908 - 1910 '' ) or two separate dates when Hardy worked on the poem ( `` 1905 and 1926 '' ) or an approximate date ( `` During the War '' ).

The history of Carlism can be usefully divided into four different stages, whose dates are only approximate ( thus the overlap is intentional ):

* Titian ( some dates approximate )

As such, dates in the following lists are approximate means.

Wendy Doniger, based on her study of indologists, assigns approximate dates to the various Puranas.

The 7 undisputed letters ( and their approximate dates ) are: 1 Thessalonians ( c. 51 AD ), Philippians ( c. 52-54 AD ), Philemon ( c. 52-54 AD ), 1 Corinthians ( c. 53-54 AD ), Galatians ( c. 55 AD ), 2 Corinthians ( c. 55-56 AD ) and Romans ( c. 55-58 AD ).

The following list was adapted from The Licchavi Kings, by Tamot & Alsop, and is approximate only, especially with respect to dates.

While it is known that radiometric dating methods can only provide approximate dates ( see also this discussion of radiocarbon dating ), the uncertainty associated with each method is known and limited.

However, viewers have been able to use dates and times displayed during the show and post-Race interviews to determine where these extended Pit Stops occur and their approximate length.

With the large number of states moving their election dates up to Mini-Tuesday for the 2008 election cycle, pundits have largely shied away from using the term again, instead choosing to reappropriate the term " Super Tuesday " to better represent the primaries held on that approximate date.

All dates are approximate.

A list of names with the approximate dates they headed the school is as follows:

Here the approximate extent of the thema of Macedonia is presented, located mostly in western Thrace

* Chinese poet Li Po is presented before the emperor and given a position in the Imperial court ( approximate date ).

So while a Likert scale is indeed ordinal, if well presented it may nevertheless approximate an interval-level measurement.

Recent evidence of the city's existence and approximate location was presented as the result of a decade-long research project based on Malay manuscripts, cartographical and topographical surveys, aerial inspections and assessments of local folklore.

The only factors that are personally set by the choreographer are the movements themselves, the number of the dancers, and the approximate total duration of the dance.

The `` approximate '' is important, because even after the order of the work has been established by the chance method, the result is not inviolable.

These data are not of the precision obtainable by the methods previously mentioned, but the vast number of approximate values available will be useful in many areas.

This, however, can only be considered approximate, as the diameter of the pulley was increased by the build-up of tape and the tape was occasionally removed from the pulley during the runs.

The discovery of CP violation helped to shed light on this problem by showing that this symmetry, originally thought to be perfect, was only approximate.

Other bilinear transforms can be used to warp the frequency response of any discrete-time linear system ( for example to approximate the non-linear frequency resolution of the human auditory system ) and are implementable in the discrete domain by replacing a system's unit delays with first order all-pass filters.

* Some curves that seem simple, such as the circle, cannot be described exactly by a Bézier or piecewise Bézier curve ; though a four-piece cubic Bézier curve can approximate a circle ( see Bézier spline ), with a maximum radial error of less than one part in a thousand, when each inner control point ( or offline point ) is the distance horizontally or vertically from an outer control point on a unit circle.

The treatment of larger molecules that contain a few dozen electrons is computationally tractable by approximate methods such as density functional theory ( DFT ).

Large molecules can be studied by semi-empirical approximate methods.

The total energy is determined by approximate solutions of the time-dependent Schrödinger equation, usually with no relativistic terms included, and by making use of the Born – Oppenheimer approximation, which allows for the separation of electronic and nuclear motions, thereby simplifying the Schrödinger equation.

Often, ray tracing methods are utilized to approximate the solution to the rendering equation by applying Monte Carlo methods to it.

The Horse Cavalry Detachment of the U. S. Army's 1st Cavalry Division is made up of active duty soldiers, still functions as an active unit, trained to approximate the weapons, tools, equipment and techniques used by the United States Cavalry in the 1880s.

If a throw lands out of bounds, unless defined by the hole, the thrower has the option of playing from the previous lie, or playing from the approximate spot where the disc crossed into the out-of-bound territory.

Thus query optimization typically tries to approximate the optimum by comparing several common-sense alternatives to provide in a reasonable time a " good enough " plan which typically does not deviate much from the best possible result.
