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 In chess, a tactic is a sequence of moves that each makes one or more immediate threats ─ that is, a check, a material threat, a checkmating sequence threat, or the threat of another tactic ─ which culminates in the opponent being unable to ... 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.

Deflection (engineering)
In structural engineering, deflection is the degree to which a part of a structural element is displaced under a load (because it deforms). It may refer to an angle or a distance. The deflection distance of a member under a load can be calculated by 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 configurations and load cases at discrete locations. Otherwise methods such as virtual work, direct integration, Castigliano's method, Macaulay's method or the direct stiffness method are used. The deflection of beam elements is usually calculated on the basis of the Euler–Bernoulli beam equation while that of a plate or shell element is calculated using plate or shell theory. An example of the use of deflection in this context is in building construction. Architects and engineers select materials for various applications. [Baidu] |
Deflection (physics)
In 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. Examples of the former include a ball bouncing off the ground or a bat; examples of the latter include a beam of electrons used to produce a picture, or the 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 reflect exactly the same amount of light cast upon it, though it may concentrate the light which is reflected into a narrower beam. *on hitting the ground, a ball previously in 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. This transfer of some energy into heat or other radiation is a consequence of the theory of thermodynamics, where, for every such interaction, some energy m ...

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 (ballistics)
{{unreferenced, date=May 2008 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 only 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), 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 a ...

Electrostatic Deflection
Electrostatic deflection refers to a way for modifying the path of a beam of charged particles by the use of an electric field applied transverse to the path of the particles. The technique is called electro''static'' because the strength and direction of the applied field changes slowly relative to the time it takes for the particles to transit the field, and thus can be considered not to change (be static) for any single particle. Explanation The Lorentz force acts on any charged particle in an electrostatic deflection. Electrostatic deflection uses a special, simplified case of this general effect by limiting the field to an electric field. An electric field applies a force on a particle that is proportional to the strength of the field and to the charge on the particle. The direction of the applied force is the same as the direction of the electric field. For electrostatic deflection, the applied electric field is arranged so that it lies in the plane perpendicular to the ini ...

Khet (game)
Khet is a chess-like abstract strategy game, abstract strategy board game using lasers that was formerly known as Deflexion. Players take turns moving Ancient Egypt, 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 Un ...

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. Howeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deflection (psychology)
Psychological projection is the process of misinterpreting what is "inside" as coming from "outside". 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 untold interpersonal damage. A bully may project their own feelings of vulnerability onto the target, or a person who is confused may project feelings of confusion and inadequacy onto other people. 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 ...

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] |
