Wikipedia
Coupling

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.

The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.

Coupling (UK TV series)

Coupling is a British television sitcom written by Steven Moffat that aired on BBC2 from 12 May 2000 to 14 June 2004. Produced by Hartswood Films for the BBC, the show centres on the dating, sexual adventures, and mishaps of six friends in their late twenties and thirties, often depicting the three women and the three men each talking among themselves about the same events, but in entirely different terms.

The series was inspired by Moffat's relationship with producer Sue Vertue, to the extent that they gave their names to two of the characters. Coupling is an example of the "group-genre", an ensemble show that had proven popular at the time. Critics compared the show to the American sitcoms Friends and Seinfeld.

The critical reaction was largely positive, and the show was named "Best TV Comedy" at the 2003 British Comedy Awards. The show debuted to unimpressive ratings, but its popularity soon increased and by the end of the third series the show had achieved respectable ratings in the UK. The series began airing on PBS stations and on BBC America in the United States in late 2002 and quickly gained a devoted fanbase there as well. The show is syndicated around the world. Short-lived American and Greek adaptations were briefly produced in 2003 and 2007 respectively. In a 2004 poll to find Britain's Best Sitcom, Coupling came 54th.

Coupling (probability)

In probability theory, coupling is a proof technique that allows one to compare two unrelated random variables(distributions) X and Y by creating a random vector W whose marginal distributions correspond to X and Y respectively. The choice of W is generally not unique, and the whole idea of "coupling" is about making such a choice so that X and Y can be related in a certain way we desire.

Coupling (computer programming)

In software engineering, coupling is the manner and degree of interdependence between software modules; a measure of how closely connected two routines or modules are; the strength of the relationships between modules.

Coupling is usually contrasted with cohesion. Low coupling often correlates with high cohesion, and vice versa. Low coupling is often a sign of a well-structured computer system and a good design, and when combined with high cohesion, supports the general goals of high readability and maintainability.

Coupling (physics)

In physics, two systems are coupled if they are interacting with each other. Of special interest is the coupling of two (or more) vibratory systems (e.g. pendula or resonant circuits) by means of springs or magnetic fields, etc. Characteristic for a coupled oscillation is the effect of beat.

The concept of coupling is particularly important in physical cosmology, in which various forms of matter gradually decouple and recouple between each other.

Coupling is also important in physics for the generation of plasmas. In electrical discharges, the coupling of an exciting field and a medium creates plasmas. The quality of the coupling of an exciting field of given frequency to a charged particle depends on resonance.

Coupling (disambiguation)

Coupling is a connection or joint between two things.

Coupling may also refer to:

  • Coupling (physics), when two systems are interacting with each other
    • Rotational–vibrational coupling, occurring when rotation frequency of an object is close to or identical to a natural internal vibration frequency
    • Angular momentum coupling, the combining of quantized angular momentum (e.g., the interaction between two nuclei in nuclear magnetic resonance)
    • Quantum coupling, when quantum states in one of the systems will cause an instantaneous change in all of the bound systems
  • Coupling (computer programming), the degree to which each program module relies on each one of the other modules
  • Coupling (electronics), the transfer of a signal from one medium or circuit block to another
  • Coupling ( genetics), a type of genetic linkage
  • Coupling (piping), a short length of pipe or tube to connect two pipes or tubes together
  • Coupling (probability), a proof technique in probability theory
  • Railway coupling, a mechanism for connecting railway rolling stock
  • Azo coupling, often called "coupling", an electrophilic substitution reaction

  • Hose coupling, a piece on the end of a hose to connect it to extra hoses or hose appliances
  • Coupling track, a term in music recording for a B-side track
  • Joint encoding, an audio compression technique in which the redundancy of information between audio channels is reduced; also commonly known as channel coupling or stereo coupling
  • Mating or the act of sexual intercourse
  • Coupling, the distance formed by the lumbar vertebrae of a horse's back.
Coupling (electronics)

In electronics and telecommunication, coupling is the desirable or undesirable transfer of energy from one medium, such as a metallic wire or an optical fiber, to another medium.

Coupling is also the transfer of electrical energy from one circuit segment to another. For example, energy is transferred from a power source to an electrical load by means of conductive coupling, which may be either resistive or hard-wire. An AC potential may be transferred from one circuit segment to another having a DC potential by use of a capacitor. Electrical energy may be transferred from one circuit segment to another segment with different impedance by use of a transformer. This is known as impedance matching. These are examples of electrostatic and electrodynamic inductive coupling.

Coupling (piping)

A coupling (or coupler) (used in piping or plumbing) is a very short length of pipe or tube, with a socket at one or both ends that allows two pipes or tubes to be joined, welded ( steel), brazed or soldered ( copper, brass etc.) together.

Alternatively it is a short length of pipe with two female National pipe threads (NPT) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female British standard pipe threads.

If the two ends of a coupling are different (e.g. one BSP threaded and one NPT threaded), then it is usually referred to as an adapter. Another variation is one plain socket and one threaded socket. Yet another variation would be 3/4" NPT to 1/2" NPT.

When the two ends use the same connection method but are of a different size, the terms reducing coupling or reducer are used.

Coupling (U.S. TV series)

Coupling is a 2003 American remake of the British television sitcom of the same title, which aired on NBC.

Coupling (Greek TV series)

Coupling is a 2007 Greek remake of the British television sitcom of the same title which aired on ANT1.

The show was directed by Stephanos Kodomari, and written by Tina Kampitsi. The series started being broadcast on November 15, 2007 at 23:00. The series was then dropped by ANT1 in February 2008 due to low ratings.
