The standard ampere is most accurately realized using a watt balance, but is in practice maintained via Ohm's Law from the units of electromotive force and resistance, the volt and the ohm, since the latter two can be tied to physical phenomena that are relatively easy to reproduce, the Josephson junction and the quantum Hall effect, respectively.

Null-A, or non-Aristotelian logic, refers to the capacity for, and practice of, using intuitive, inductive reasoning ( compare fuzzy logic ), rather than reflexive, or conditioned, deductive reasoning.

In practice, anyone who creates tangible or intangible objects, such as consumer products, processes, laws, games and graphics, is referred to as a designer.

Coupled with the Amiga's ability to use a Genlock, this allowed for the Laserdisc video to be overlaid with computer graphics and integrated into presentations and multimedia displays, years before such practice was commonplace.

However, due to large-scale fan complaints that this ' flipping ' has changed the finished product from the original ( e. g. A flipped manga image will keep the speech translations legible, while any graphics such as the wording on clothes or buildings will be reversed and confusing ), this practice has largely diminished.

In practice its main competitors were chipset-integrated graphics solutions, such as Intel's 845G and Nvidia's own nForce 2, but its main advantage over those was multiple-monitor support ; Intel's solutions did not have this at all, and the nForce 2's multi-monitor support was much inferior to what the MX series offered.

While the protocol itself has features for reading and writing of video streams from and to video adapters, in practice today only the functions < tt > XvPutImage </ tt > and < tt > XvShmPutImage </ tt > are used: the client program repeatedly prepares images and passes them on to the graphics hardware to be scaled, converted and displayed.

It is never actually used in practice computationally, but is conceptually useful in understanding other concepts in vision and graphics.

In November 2002, NVIDIA started the practice of featuring realistic female characters in graphics card technology demos, by releasing Dawn for its GeForce FX card.

Computer graphics: principles and practice.

tp bennett has three core divisions of architecture, interiors and planning supported by specialist practice areas in strategy, research and graphics.

Visual sociology also requires the development of new forms — for example, data driven computer graphics to represent complex relationships e. g., changing social networks over time, the primitive accumulation of capital, the flow of labor, relations between theory and practice.

As this could cause a serious fire when the switch was released it became common practice for part or all of the bottom of the basically circular cowling fitted to most rotary engines to be cut away, or fitted with drainage slots.

Among them are reducing Friday practice sessions ; banning active suspension, launch control and ceramic composite brakes ; extending the lifespan of engines ; and reducing testing sessions.

In practice though, many input method engines use a tabular lookup method for all table based input systems, including for Wubi.

Thirdly, although this engine used positive steam pressure to push water up out of the engine ( with no theoretical limit to the height to which water could be lifted by a single high-pressure engine ) practical and safety considerations meant that in practice, to clear water from a deep mine would have needed a series of moderate-pressure engines all the way from the bottom level to the surface.

The Vega production cars ( Facel FV, later and more famously the HK500 ) appeared in 1954 using Chrysler V8 engines, at first a DeSoto Hemi engine ; the overall engineering was straightforward, with a tubular chassis, double wishbone suspension at the front and a solid driven axle at the back, as in standard American practice.

There is a common legend that in 1713 a cock boy named Humphrey Potter, whose duty it was to open and shut the valves of an engine he attended, made the engine self-acting by causing the beam itself to open and close the valves by suitable cords and catches ( known as the " potter cord "); however the plug tree device ( the first form of valve gear ) was very likely established practice before 1715 and is clearly depicted in the earliest known images of Newcomen engines by Henry Beighton 1717 ( believed by Hulse to depict the 1714 Griff colliery engine ) and by Thomas Barney ( 1719 ) ( depicting the 1712 Dudley Castle engine ).

Boulton and Watt's practice was to help mine-owners and other customers to build engines, supplying men to erect them and some specialised parts.

For example: In the early days of jet transportation, crushed walnut shells were used to scour the compressor airfoils clean, but when engines with air cooled vanes and blades in the turbine started being manufactured, this practice was stopped because the crushed shells tended to plug up the cooling passages to the turbine, resulting in turbine failures due to overheating.

It is common practice for Vee engines to be described with " V #" notation, where # is how many cylinders it has:

These engines were intended to give an output of at 1, 000 rpm but in practice had a continuous output rating of only at 900 rpm.

For business jets, the rear-engined universal configuration pioneered by the turbojet-powered early Learjet 23, North American Sabreliner, and Lockheed JetStar is common practice on smaller bizjet aircraft as the wing is too close to the ground to accommodate underslung engines.

In stationary steam engines, traction engines and marine engine practice, the shortcomings of valves and valve gears were among the factors that lead to compound expansion.

This probably explains why radial gears were largely superseded by Walschaerts-type gears in railway practice but continued to be used in traction and marine engines.
