Feathering
Feathering is a technique used in computer graphics software to smooth or blur the edges of a feature. The term is inherited from a technique of fine retouching using fine feathers. Paintbrush feathering Feathering is most commonly used on a paintbrush tool in computer graphics software. This form of feathering makes the painted area appear smooth. It may give the effect of an airbrush or spraypaint. Color is concentrated at the center of the brush area, and it blends out toward the edges. Selection feathering Feathering is not only used on paintbrushes in computer graphics software. Feathering may also blend the edges of a selected feature into the background of the image. When composing an image from pieces of other images, feathering helps make added features look "in place" with the background image. For instance, if someone were to want to add a leaf to a photograph of grass using computer graphics software, he or she might use feathering on the leaf to make it blen ...

Leading
In typography, leading ( ) is the space between adjacent lines of type; the exact definition varies. In hand typesetting, leading is the thin strips of lead (or aluminium) that were inserted between lines of type in the composing stick to increase the vertical distance between them. The thickness of the strip is called leading and is equal to the difference between the size of the type and the distance from one baseline to the next. For instance, given a type size of 10 points and a distance between baselines of 12 points, the leading would be 2 points. The term is still used in modern page-layout software such as QuarkXPress, the Affinity Suite, and Adobe InDesign. Consumer-oriented word-processing software often talks of line spacing or, more accurately, interline spacing. Origins The word comes from lead strips that were put between set lines of lead type, hence the pronunciation "ledding" and not "leeding". The practice became popular in the eighteenth ...

Feathering (reentry)
Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: ''uncontrolled entry'', such as the entry of astronomical objects, space debris, or bolides; and ''controlled entry'' (or ''reentry'') of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass (ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Crewed space vehicles must be slowed to subsonic speeds be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feathering (propeller)
An aircraft propeller, also called an airscrew,Beaumont, R.A.; ''Aeronautical Engineering'', Odhams, 1942, Chapter 13, "Airscrews". converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type. The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials. Propellers are most suitable for use at subsonic airspeeds generally below about , although supersonic speeds were achieved in the McDonnell XF-88B experimental propeller-equipped aircraft. Supersonic tip-speeds are used in some aircraft like the Tupolev Tu-95, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feathering (clutch)
Clutch control refers to the act of controlling the speed of a vehicle with a manual transmission by partially engaging the clutch plate, using the clutch pedal instead of (or in conjunction with) the accelerator pedal. The purpose of a clutch is in part to allow such control; in particular, a clutch provides transfer of torque between shafts spinning at different speeds. In the extreme, clutch control is used in performance driving, such as starting from a dead stop with the engine producing maximum torque at high RPM. Overview With the clutch pedal completely pressed or a motorcycle's lever pulled entirely towards the driver, there is no direct link between the engine and the driveshaft, so no power can pass from the engine to the driveshaft and wheels. With the pedal entirely released, there is full contact between the engine and the driveshaft, via the clutch plate, which means that the engine can apply power directly to the driveshaft. However, it is possible to have the cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarring And Feathering
Tarring and feathering is a form of public torture and punishment used to enforce unofficial justice or revenge. It was used in feudal Europe and its colonies in the early modern period, as well as the early American frontier, mostly as a type of mob vengeance. The victim would be stripped naked, or stripped to the waist. Wood tar (sometimes hot) was then either poured or painted onto the person while they were immobilized. Then the victim either had feathers thrown on them or was rolled around on a pile of feathers so that they stuck to the tar. The image of a tarred-and-feathered outlaw remains a metaphor for severe public criticism. Early history The earliest mention of the punishment appears in orders that Richard I of England issued to his navy on starting for the Holy Land in 1189. "Concerning the lawes and ordinances appointed by King Richard for his navie the forme thereof was this ... item, a thiefe or felon that hath stolen, being lawfully convicted, shal have hi ...

Feathering (horse)
Feathering or feather is the long hair on the lower legs of some breeds of horse and pony. On some horses, especially draft breeds, the hair can almost cover the hooves. While nearly all horses will grow longer hair on the lower legs and back of the fetlocks at times, particularly in the winter, "feather" refers to the particularly long growth that is characteristic of certain breeds. Feathering is a characteristic trait of the many of the Mountain and moorland pony breeds of the United Kingdom as well as draught breeds such as the Clydesdale, Shire, Friesian, Ardennes horse The Ardennais or Ardennes is one of the oldest breeds of draft horse, and originates from the Ardennes area in Belgium, Luxembourg, and France. They are heavy-boned with thick legs and are used for draft work. Their history reaches back to A ... and Gypsy Vanner. The trait may appear in crossbreds of these breeds, though to date there has been little scientific study of the trait. References Ho ...

Fletching
Fletching is the fin-shaped aerodynamic stabilization device attached on arrows, bolts, darts, or javelins, and are typically made from light semi-flexible materials such as feathers or bark. Each piece of such fin is a fletch, also known as a flight or feather. A fletcher is a person who attaches fletchings to the shaft of arrows. The word is related to the French word , meaning 'arrow', via the ultimate root of Old Frankish . Description As a noun, ''fletching'' refers collectively to the fins or vanes, each of which individually is known as a fletch. Traditionally, the fletching consists of three matched half-feathers attached near the back of the arrow or shaft of the dart that are equally spaced around its circumference. Four fletchings have also been used. In English archery, the male feather, from a cock, is used on the outside of the arrow, while the other two stabilizing feathers are from a female, or hen. Traditional archery lore about feather curvature is that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
