Diopter adjustment, английский
Adjusts the optical viewfinder`s magnification factor to suit the eyesight of the user. look for a knob or dial next to or beneath the viewfinder`s eyepiece. not all cameras have this feature.

Dioptometer, английский
Dioptra, ae, f, латинский
Dioptre, английский
A unit of measurement of the refraction of a lens (note: the us spelling is diopter.) comment: a one dioptre lens has a focal length of one metre; the greater the dioptre, the shorter the focal length.
Dioptre adjustment, английский
This adjusts the optical viewfinder’s magnification factor to suit the eyesight of the cameras user. there should be a knob or dial near the viewfinders eyepiece, however, not all cameras have this feature.

Prism, английский
- Triangular shaped glass or other transparent material. when light is passed through a prism, its wavelengths refract into a rainbow of colors. this demonstrates that light is composed of color and indicates the arrangement of colors in the visible spectru

- In dioptrics, is a geometrical solid bounded by three parallelograms, whose bases are equal triangles.

- A credit card fraud monitoring system. it was developed in part from the application of knowledge discovery in databases (kdd) techniques see also: knowledge discovery in databases. probabilistic context free grammar (pcfg) these are grammars that are developed from large databases of text. the grammars attach probabilities to the various productions in the grammar. if the grammars are developed using supervised learning (i.e., a tagged text corpus), the probabilities can be directly estimated by counting the various productions and perhaps smoothing or otherwise post-processing the results. for an unsupervised corpus, some form of estimation and maximization strategy needs to be employed.
Prism glass, английский
Prism pairs, английский
Combinations of two prisms, mostly used for dispersion compensation

Holding company for cardiff railway company
Prism segment, английский
A straight-top glass bifocal lens with the “base in” prism ground in the segment portion only. prism thinning (equi-thin)– the reduction of inherent thickness in the upper portion of certain type of mutifocal lenses by grinding equal basedown prism in each lens of a pair; the lower portions in certain type lenses tend to be thinner than the upper portions. thickness and weight are reduced due this procedure causing a more pleasing pair of spectacles.
Prismatic, английский
Prismatic billet molding, английский
A common norman molding consisting of a series of prisms, with alternate rows staggered.
Deflection, английский
- The deference between a tire's unloaded or free radius and the loaded radius.
- Vertical distance between the chord and the skyline, measured at midspan; frequently expressed as a percentage of the horizontal span length (22).
- The displacement of a structural member or system under load.
- Отклонение
- The ricochet of a ball after it hits a player.
- The tendency of a ship from her true course; the departure of the magnetic needle from its true bearing, when influenced by iron or the local attraction of the mass. in artillery, the deviation of a shot from the direction in which it is fired. the term is usually reserved to lateral deviations, especially those resulting from irregular causes—those constant ones due to the regular motion of rifled projectiles coming under either of the designations “constant deflection,” “derivation,” borrowed from the french, or “drift,” from the americans. these latter, according to the direction usually given to the rifling in the present day, all tend away to the right, though they include some subordinate curves not yet distinctly determined.
- [1] gunnery term for the angle between the line-of-sight to the target and the line-of-sight to which the gun must be pointed to compensate for movement, wind, etc. [2] deviation of a compass needle caused by local magnetic influence, especially on a ship.
- A change in the intended course of a borehole produced intentionally or unintentionally by various conditions encountered in the drill hole or by the operational characteristics of the drilling equipment used. also called deviation.
- Отклонение от прямого направления отклонение магнитной стрелки; отклонение стрелки (приборов)
- See static tire deflection,
Centimeter, английский
- Сантиметр
- In the metric system, a measure of length equal to a hundredth part of a meter, or 0.3937+ in.; abbreviated cm; an inch equals 2.54 cm. central air-conditioning system an airconditioning system in which the air is treated by equipment at one or more central locations outside the spaces served, and conveyed to and from these spaces by means of fans and pumps through ducts and pipes. central air-handling unit an air-handling unit in which treated air is distributed to a number of spaces by means of ductwork.

Prescription laboratories, английский
Transforms semifinished lenses into finished lenses and then edges and glazes into frames. prism ( ? ) – a wedged-shaped piece of lens material, using a symbol ?, that bends light, but does not refract light, in the direction of its base. prism grinding is incorporated into spectacle lenses to help relieve eyestrain caused by weak eye muscles and/or to make the optical and mechanical centers coincide.
