Precise indications of this are found in the registers of the Inquisitors, Bernard of Caux, Jean de St Pierre, Geoffroy d ' Ablis, and others.

Precise credit is at times difficult or contentious because scientific language and standards of proof changed, so whether medieval statements are equivalent to modern statements or sufficient proof, or instead similar to modern statements and hypotheses is often debatable.

Several significant general aviation companies are based at Bend Airport, including Precise Flight, which develops oxygen systems, speed brakes, landing lights and other modifications for general aviation aircraft, Epic Aircraft and Cessna.

*" The Precise Ethnographer " – Ethnographers often create the illusion that field notes are data and reflect what " really " happened.

Precise determination of these two properties with chemical, X-ray diffraction, or petrographic analysis are required for identification.

Precise figures on the ethnic composition of Belgium are impossible to obtain, for the language question is so controversial that the Belgian census has not included data on linguistic composition of communes since 1947.

Precise comparisons of the efficacy of competing paradigms are frequently made more difficult because of new and differing terminology applied to similar ( but not identical ) entities and processes together with numerous implementation distinctions across languages.

Precise technical terms and their definitions are formally recognised, documented, and taught by educators in the field.

Precise dates are sometimes a matter of debate amongst historians.

Precise figures on faction membership do not exist, but the best estimates of the numerical strength of the major factions are provided below.

Precise details of this trek are recorded in the published diaries of the expedition's non-African " officers " ( e. g. Major Edmund Musgrave Barttelot, Captain William Grant Stairs, Mr. A. J.

Precise representations of distinct individuals demonstrate that people are more accurate in estimating amounts and distinguish amount differences, when the numbers are relatively smaller.

Precise measurements are maintained on this tree by ENTS.

Precise dating of many of the early civilizations is difficult because there are few text sources.

Precise measurements of the relative positions of the inner planets can be made by radar and by telemetry from space probes.

Precise navigation would enable United States submarines to get an accurate fix of their positions prior to launching their SLBMs.

Precise knowledge of the positions of aircraft would permit a reduction in the normal procedural separation standards, which in turn promised considerable increases in the efficiency of the airways system.

: Precise instructions ( in language understood by " the computer ") for a fast, efficient, " good " process that specifies the " moves " of " the computer " ( machine or human, equipped with the necessary internally contained information and capabilities ) to find, decode, and then process arbitrary input integers / symbols m and n, symbols + and =

Precise metric odometers have a precision of 1 / 100 or 1 / 1000 km, 10 or 1 metre ( s ) respectively.

Precise mathematical labeling of afterload and preload is a challenge since both maximum measurements ( volume / tension ) occur simultaneously in late systole.

Precise use of adjectives, similes, metaphors to create images / pictures in the mind e. g. their noses were met with the acrid smell of rotting flesh.

The kissing circles in this problem are sometimes known as Soddy circles, perhaps because Soddy chose to publish his version of the theorem in the form of a poem titled The Kiss Precise, which was printed in Nature ( June 20, 1936 ).

Kriging is a group of geostatistical techniques to interpolate the value of a random field ( e. g., the elevation, z, of the landscape as a function of the geographic location ) at an unobserved location from observations of its value at nearby locations.

His observations were made with very simple instruments, an ordinary plumb-line being used for measuring the angles of elevation of the stars.

interpolates the value of a random field ( e. g. the elevation of the landscape as a function of the geographic location ) at an unobserved location from observations of the random field at nearby locations.

Her writings are remarkable, according to Fontenelle, " for the tone of amiable virtue that reigns throughout ," and, according to Louis Simon Auger, " for the purity of the style and the morality, the elevation of the sentiments, the fineness of the observations and the ideas.

Additionally, observations demonstrate that the Uxbridge wedge, which sits at an elevation of 335 m, was produced by an ice-confined sedimentation pattern in a lake which water level was controlled by the Campbellville outlet.

In the relatively short time since these early observations, Venus has been observed at additional wave lengths in the range from 0.8 to 10.2 cm, and Jupiter has been observed over the wave-length range from 3.03 to 68 Aj.

Results from this approach amply confirm the direct observations: about three years are required, there being a possible slight difference between males and females in the time required.

Contrary to observations with ethers, no apparent change of the reactivity of the chain ends takes place over considerable periods of time in benzene as solvent.

It is instrumental for keeping time, in that UTC is basically the atomic time synchronized to Earth's rotation by means of exact observations.

Informally, it is the similarity between observations as a function of the time separation between them.

In 2006 and 2007, J. D. Monnier and his coworkers produced an image of Altair's surface from 2006 infrared observations made with the MIRC instrument on the CHARA array interferometer ; this was the first time the surface of any main-sequence star, apart from the Sun, had been imaged.

However neither of those observations became accepted by British economists at the time.

Two other satellites made observations at the time of the impact: the Ulysses spacecraft, primarily designed for solar observations, was pointed towards Jupiter from its location 2. 6 AU away, and the distant Voyager 2 probe, some 44 AU from Jupiter and on its way out of the Solar System following its encounter with Neptune in 1989, was programmed to look for radio emission in the 1 – 390 kHz range.

ET, in turn, can now be seen ( in light of modern results ) as close to the average mean solar time between 1750 and 1890 ( centered on 1820 ), because that was the period during which the observations on which Newcomb's tables were based were performed.

Partly because the observations were at the very limits of instrumental capabilities at the time, astronomers remained skeptical for several years about this and other similar observations.

( where " the times of observation are in Universal time, not corrected to Newtonian time ", and 0. 0748B represents an irregular fluctuation calculated from lunar observations ).

The availability of atomic clocks, together with the increasing accuracy of astronomical observations ( which meant that relativistic corrections were at least in the foreseeable future no longer going to be small enough to be neglected ), led to the eventual replacement of the ephemeris time standard by more refined time scales including terrestrial time and barycentric dynamical time, to which ET can be seen as an approximation.

This SI second referred to atomic time was later verified by Markowitz ( 1988 ) to be in agreement, within 1 part in 10 < sup > 10 </ sup >, with the second of ephemeris time as determined from lunar observations.

ECMWF has pioneered an innovative approach known as reanalysis, which involves feeding weather observations collected over decades into a NWP system to recreate past atmospheric, sea-and land-surface conditions over specific time periods to obtain a clearer picture of how the climate has changed.

Time-series data sets contain observations over time ; for example, inflation over the course of several years.

Cross-sectional data sets contain observations at a single point in time ; for example, many individuals ' incomes in a given year.

Multi-dimensional panel data sets contain observations across time, cross-sectionally, and across some third dimension.
