Deflection (chess)
Deflection in chess is a tactic that forces an opposing piece to leave the square, rank or file it occupies, thus exposing the king or a valuable piece. It is typically used in the context of a combination or attack, where the deflected piece is critical to the defence. Deflection may be used as a gambit to cause an opponent's piece to move to a less suitable square. Deflections are often used as part of a combination which may involve other types of chess tactics as well. If the deflected piece happens to be an overworked piece then the opponent's defense instantly crumbles, making victory imminent to the one who employed the deflection.

Khet (game)
Khet is a chess-like abstract strategy board game that uses lasers, and was formerly known as Deflexion. Players take turns moving Egyptian-themed pieces around the playing field, firing their low-powered laser diode after each move. Most of the pieces are mirrored on one or more sides, allowing the players to alter the path of the laser through the playing field. When a piece is struck by a laser on a non-mirrored side, it is eliminated from the game. Under its original name, the game was a Mensa Select Award winner. Its name was changed on September 15, 2006. The new game retains the same rules of gameplay, but has a different design, including a new color scheme and a new box design. Under the new name, the game was one of five finalists for the 2007 Toy of the Year award. History Professor Michael Larson and two students, Del Segura and Luke Hooper, designed the game as a class project at Tulane University. (Professor Larson is now at the University of Colorado.)

Deflection (ballistics)
Deflection shooting is a technique of shooting ahead of a moving target, also known as leading the target, so that the projectile will "intercept" and collide with the target at a predicted point. This technique is necessary when the target will have significantly displaced its position during the time the projectile would take to reach the target, which can become the case over very long distances (e.g. a long sniper shot), due to fast moving targets (e.g. aerial dogfight against an opposing aircraft, or anti-aircraft fire against passing aircraft), hunting a running animal, or while using relatively slow projectiles (e.g. a bolt shot from a crossbow, or a basketball thrown to a running teammate). Gyro gunsights developed for aircraft of the Second World War displayed a reticle that compensated for target lead. Modern fighter aircraft have automated deflection sights, where a computer calculates lead and projects the solution onto a head-up display (HUD). The visual assistan ...

Deflection (engineering)
In structural engineering, deflection is the degree to which a part of a long structural element (such as Beam (structure), beam) is deformation (mechanics), deformed laterally (in the direction transverse to its longitudinal axis) under a Structural load, load. It may be quantified in terms of an angle (angular displacement) or a distance (linear displacement (geometry), displacement). A longitudinal deformation (in the direction of the axis) is called ''elongation (mechanics), elongation''. The deflection distance of a member under a load can be calculated by Integral, integrating the function that mathematically describes the slope of the deflected shape of the member under that load. Standard formulas exist for the deflection of common Beam (structure), beam configurations and load cases at discrete locations. Otherwise methods such as virtual work, Direct integration of a beam, direct integration, Castigliano's method, Macaulay's method or the direct stiffness method are use ...

Deflection (physics)
Deflection is a change in a moving object's velocity, hence its trajectory, as a consequence of contact (collision) with a surface or the influence of a non-contact force Field (physics), field. Examples of the former include a ball bouncing off the ground or a bat; examples of the latter include a Cathode ray, beam of electrons used Cathode ray tube, to produce a picture, or the General relativity#Light deflection and gravitational time delay, relativistic bending of light due to gravity. Deflective efficiency An object's deflective efficiency can never equal or surpass 100%, for example: *a mirror will never Reflection (physics), reflect exactly the same amount of light cast upon it, though it may concentrate the light which is reflected concave mirror, into a narrower beam. *on hitting the ground, a ball previously in Free fall, free-fall (meaning no force other than gravity acted upon it) will never bounce back up to the place where it first started to descend.

Deflexion (linguistics)
Deflexion is a diachronic linguistic process in inflectional languages typified by the degeneration of the inflectional structure of a language. All members of the Indo-European language family are subject to some degree of deflexional change. This phenomenon has been especially strong in Western European languages, such as English, French, and others. Deflexion typically involves the loss of some inflectional affixes, notably affecting word endings ( markers) that indicate noun cases, verbal tenses and noun classes. This is part of a process of gradual decline of the inflectional morphemes, defined as atomic semantic units bound to abstract word units (lexemes). Complete loss of the original subset of affixes combined with a development towards allomorphy and new morphology is associated in particular with creolization, i.e. the formation of pidgins and creole languages. Directly related to deflexion is the languages becoming less synthetic and more analytic in nature. Howe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deflection (psychology)
Psychological projection is a defence mechanism of alterity concerning "inside" ''content'' mistaken to be coming from the "outside" Other. It forms the basis of empathy by the projection of personal experiences to understand someone else's subjective world. In its malignant forms, it is a defense mechanism in which the ego defends itself against disowned and highly negative parts of the self by denying their existence in themselves and attributing them to others, breeding misunderstanding and causing interpersonal damage. Projection incorporates blame shifting and can manifest as shame dumping. Projection has been described as an early phase of introjection. Historical precursors A prominent precursor in the formulation of the projection principle was Giambattista Vico. In 1841, Ludwig Feuerbach was the first enlightenment thinker to employ this concept as the basis for a systematic critique of religion. The Babylonian Talmud (500 AD) notes the human tendency toward projecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deflection Routing
Deflection routing is a routing strategy for networks based on packet switching which can reduce the need of buffering packets. Every packet has preferred outputs along which it wants to leave the router, and when possible, a packet is sent along one of these outputs. However, two or more packets may want to leave along the same output (which is referred to as a ''contention among packets''), and then only one of the packets may be sent along the link, while the others are sent along available outputs, even though the other links are not preferred by the packets (because, for instance, those links do not yield shortest paths). Depending on the rate of incoming packets and the capacity of the outgoing links, deflection routing can work without any packet buffering. Of course, it is always possible to simply drop packets in a network with a best-effort delivery strategy.

Deflection Yoke
A deflection yoke is a kind of magnetic lens, used in cathode ray tubes to scan the electron beam both vertically and horizontally over the whole screen. In a CRT television, the electron beam is moved in a raster scan on the screen. By adjusting the strength of the beam current, the brightness of the light produced by the phosphor on the screen can be varied. The cathode ray tube allowed the development of all-electronic television. Electromagnetic deflection yokes are also used in certain radar displays. Magnetic compared to electrostatic deflection Another way of deflecting an electron beam is to put two pairs of electrodes inside the CRT, after the electron gun structure. Electrostatic deflection is common in oscilloscope displays, because it is easier to drive deflection plates at high frequencies, compared to driving the large inductance of a deflection yoke. Compared with electrostatic deflection, magnetic deflection has fewer obstructions inside the tube and so allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrostatic Deflection
Electrostatics is a branch of physics that studies slow-moving or stationary electric charges. Since classical antiquity, classical times, it has been known that some materials, such as amber, attract lightweight particles after triboelectric effect, rubbing. The Greek language, Greek word (), meaning 'amber', was thus the Root (linguistics), root of the word ''electricity''. Electrostatic phenomena arise from the forces that electric charges exert on each other. Such forces are described by Coulomb's law. There are many examples of electrostatic phenomena, from those as simple as the attraction of plastic wrap to one's hand after it is removed from a package, to the apparently spontaneous explosion of grain silos, the damage of electronic components during manufacturing, and photocopier and laser printing, laser printer operation. The electrostatic model accurately predicts electrical phenomena in "classical" cases where the velocities are low and the system is macroscopic so ...
