The quantity of anything, as water, displaced by a floating body, as by a ship, the weight of the displaced liquid being equal to that of the displacing body.

Displacement compressor Displacement of a compressor

The total weight of the canoe, passengers and gear.

applies only to positive-displacement compressors. It is the net volume swept by the moving parts in a unit of time, usually one minute.

The process of extracting soluble substances from organic material and the like, whereby a quantity of saturated solvent is displaced, or removed, for another quantity of the solvent.

(n) The linear or angular distance moved by a part or mechanism. In cam design, a displacement diagram is used to chart the linear location of the follower relative to the angular position of the cam.

The apparent change in position of objects in an aerial photograph which project above (or below) scale datum. This is a geometric feature of photography that is normal and in many cases useful to the interpretation process.

a shift of criminal activity from one spatial location to another.

A Freudian term designating the process, or result, of redirecting an emotion or impulse from its original object to a more acceptable one. When a child who is angry at a friend expresses hostility toward a sibling, the anger is displaced. Displacement has been invoked along with condensation by psychoanalytically oriented semioticians and others to illuminate the way language works.

type of behaviour in which one transfers anger at one person to another person or object.

A defense mechanism, operating unconsciously, in which emotions, ideas, or wishes are transferred from their original object to a more acceptable substitute; often used to allay anxiety.

a) A defense mechanism whereby a motive that may not be directly expressed (such as sex or aggression) appears in a more acceptable form. See also defense mechanism. b) The principle of loss of items from short-term memory as too many new items are added. See also chunk, short-term memory.

Displacement and substitution are two closely related terms which are used to describe situations where the effects of an intervention on a particular individual, group or area are only realised at the extent of other individuals, groups or areas. Consider, for example, the case of a programme to provide employment subsidies. In a firm which benefits from this programme, subsidised workers may take the place of unsubsidised workers who would otherwise have been employed by that firm. This is known as substitution. Alternatively, a firm benefiting from the employment subsidies may win business from other firms which do not participate in the scheme. Thus, the jobs created in the participating firm may be partly or wholly offset by job losses in other firms. This is known as displacement.

Displacement transactions permit the lateral movement of gas through a transportation network. The configuration of many pipelines is such that it may not be apparent whether a given movement of gas is forward or backward from the point of receipt. It can be argued that all transportation service is performed by displacement as the physical delivery of the same molecules of gas is impossible. See BACKHAUL.

The project should not cause significant displacement of jobs or market share in any other UK business. At the risk of over-simplification, the host market should be sufficiently dynamic and capable of supporting the forecast increase in output without excessively compromising the performance of existing competitors. If the alternative is to locate the project outside the UK, displacement is less of an issue (if at all). With this argument, it is normally accepted that additional capacity is to be created regardless of project location. The competitive outcome will not change as a direct result of public subsidy and the alternative is less attractive to the UK economy. Similarly, increased exports and import substitution reduce the effect of any displacement issues on the application.

The substitution of less expensive energy generation for more expensive generation. Usually this means reducing or shutting down production at a high cost thermal plant and using cheaper thermal generation and/or hydroelectric power when it is available.

the characteristic of language marked by the ability to refer to objects and events that are not present. 327

The distance and direction that an object has moved in a given time period.

For Freud, a process by which energy that is blocked from being put into in an object is put into in another object.

when agents, objects or steps are anchored, this is an estimate of the difference between the anchored measure and the measure which would accord with the current data set.

Turning or ducking to move a valid target area from its normal position, replacing it with a non-valid area.

ESP responses to targets other than those for which the calls were intended.

turning or ducking to move the target area away.

turning or ducking to remove the target area from its normal position, resulting in the non-valid target being substituted for the valid target

The ability to communicate about events at times and places other than those of their occurrence; enables a person to talk and think about things not directly in front of him or her.

an event in which something is displaced without rotation

an event that changes horizons, expectations, profit or behavior

A basic feature of language; the ability to speak of things and events that are not present.

The act of displacing, or the state of being displaced; a putting out of place.

act of taking the place of another especially using underhanded tactics

The act or feeling of being removed or alienated from a place or people.

the act of uniform movement

A movement term that describes the moving of a part of a vehicle beyond its normal operating range, making space for the access and removal of trapped patients.

Any movement of a particle or a body as a whole.

A dislocation caused by a slipping of rock masses along a plane of fracture.

The amount of movement or slip across a fault plane.

Camera displacements are a feature of Large Format studio cameras that allow the relationship between the film plane and the lens plane to be altered in order to alter and control the perspective of the image. By using displacements it is possible for example to look up at a building and keep the vertical sides of the building parallel without having the keystone effect normally experienced with a camera.Digital cameras do not work well with significant displacements. The control of perspective is often best left to be accomplished in Photoshop
