The formal displacement of the geocentric principle far from being Copernicus' primary concern, was introduced only to resolve what seemed to him intolerable in orthodox astronomy, namely, the ' unphysical ' triplication of centric reference-points: one center from which the planet's distances were calculated, another around which planetary velocities were computed, and still a third center ( the earth ) from which the observations originated.

As a result, about one third of the volume of the transient crater is formed by the ejection of material, and the remaining two thirds is formed by the displacement of material downwards, outwards and upwards, to form the elevated rim.

This relation, however, is a psychological one in contrast to the physical relation implied by Wien's displacement law, according to which the spectral peak is shifted towards shorter wavelengths ( resulting in a more blueish white ) for higher temperatures.

A single-bit transmission error then corresponds to a displacement from a valid corner ( the correct message and checksum ) to one of the m adjacent corners.

Her displacement was 380 tons, and she was armed with one 90 mm Hontoria gun, four 57 mm Nordenfelt guns, two 37 mm Hotchkiss cannons and 3 Schwarzkopf torpedo tubes.

Eritrea suffered from significant economic and social stress, including massive population displacement, reduced economic development, and one of Africa's more severe land mine problems.

As was observed after other disasters involving destruction and loss of life and their media depictions, such as those of the 2001 World Trade Center Attacks or Hurricane Katrina — and has been recently observed in the 2010 Haiti earthquake, it is also important not to pathologize the reactions to loss and displacement or disruption of governmental administration and services, but rather to validate these reactions, to support constructive problem-solving and reflection as to how one might improve the conditions of those affected.

Soal discovered, to his surprise, that four of his former participants, Randolph Tucker Pendleton IV, Amanda Bailey, Ling Dao and Rachel Brown, evidenced displacement: i. e., their responses significantly corresponded to targets for trials one removed from which they were assigned.

The visual scene change is essentially one of change of perspective and / or displacement of objects such as the horizon, which takes some time to build up to discernible amounts after the initial acceleration which caused the displacement.

The displacement of volume for one revolution is first determined.

In 2006 Turkmenistan had eight merchant marine vessels of more than 1, 000 tons displacement, of which four were cargo ships, two were oil tankers, one was for refrigerated cargo, and one was a combination ore and oil ship.

Momentum transfer pumps in conjunction with one or two positive displacement pumps are the most common configuration used to achieve high vacuums.

The displacement of mercury which took place when the cell was short-circuited, only took place very slowly when an ebonite plate, covered with a sheet of copper of high resistance, was inserted between one of the poles of the cell, and the corresponding electrode of the electrometer ; but when sparks were produced by a machine, the mercury was rapidly thrown into the capillary tube owing to the sudden diminution in the resistance of the plate.

The Japanese regulations for calculating displacements for engine ratings use the volume displacement of one rotor face only, and the auto industry commonly accepts this method as the standard for calculating the displacement of a rotary.

A calculation of this form dictates that a two rotor Wankel displacing 654 cc per face will have a displacement of 1. 3 liters per every rotation of the eccentric shaft ( only two total faces, one face per rotor going through a full power stroke ) and 2. 6 liters after two revolutions ( four total faces, two faces per rotor going through a full power stroke ).

Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium — that is, with little or no associated mass transport.

The displacements are said to be out of phase by one quarter of a cycle because the horizontal maximum displacement ( toward the left ) is reached one quarter of a cycle before the vertical maximum displacement is reached.

and one for the D-field ( called the electric displacement ):

The marimba is a non-transposing instrument with no octave displacement, unlike the xylophone which sounds one octave higher than written and the glockenspiel which sounds two octaves higher than written.

The original carrier for the plague-infected fleas thought to be responsible for the Black Death was the black rat, and it has been hypothesized that the displacement of black rats by brown rats led to the decline of bubonic plague.

It can be thought of as a modified Cartesian plane, with the real part of a complex number represented by a displacement along the x-axis, and the imaginary part by a displacement along the y-axis.

For most balance and gait disorders, some form of displacement exercise is thought helpful ( for example walking, jogging, or bicycling but not on a treadmill or stationary bicycle ).

Although complex and controversial, the main factor in the eastern gray squirrel's displacement of the red squirrel is thought to be its greater fitness and, hence, a competitive advantage over the red squirrel on all measures.

The " 465 " sticker on the air cleaner did not denote engine displacement as many thought, it denoted the torque rating.

Thickness noise is dependent only on the shape and motion of the blade, and can be thought of as being caused by the displacement of the air by the rotor blades.

It is good to be able to compute displacement so that changes in it resulting from boring and stroking can be computed.

Actually, the engine displacement formula is the standard formula for computing the volume of a cylinder of any type with an added factor that represents the number of cylinders in the engine.

A cylinder's compression ratio is computed by comparing the cylinder's volume, or its displacement, with the total volume of the cylinder and its combustion chamber.

Cylinder volume is determined in exactly the same manner as for the displacement formula: Af.

The actual mean of 1.07 being about halfway between 0 of complete correlation and 2.0 of no correlation, it is evident that there is a pretty fair degree of similarity in the behavior even of particular individual items of meaning as regards long-term stem displacement.

The color of amethyst has been demonstrated to result from substitution by irradiation of trivalent iron ( Fe < sup > 3 +</ sup >) for silicon in the structure, in the presence of trace elements of large ionic radius, and, to a certain extent, the amethyst color can naturally result from displacement of transition elements even if the iron concentration is low.

The maximum amount of the aberrational displacement of a star is approximately 20 arcseconds in right ascension or declination.

Modern figures give a proper motion of 7 arcseconds / year, distance 30 light years, so the displacement is 3 arcminutes and a half.

The term " ethnic cleansing " was used as an alternative to " genocide " to denote not just ethnically motivated murder but also displacement, though critics charge there is no difference.

There are two parts to Einstein's theory: the first part consists in the formulation of a diffusion equation for Brownian particles, in which the diffusion coefficient is related to the mean squared displacement of a Brownian particle, while the second part consists in relating the diffusion coefficient to measurable physical quantities.

From this expression Einstein argued that the displacement of a Brownian particle is not proportional to the elapsed time, but rather to its square root.

The vector joining the positions of a particle in the undeformed configuration and deformed configuration is called the displacement vector, in the Lagrangian description, or, in the Eulerian description.

A displacement field is a vector field of all displacement vectors for all particles in the body, which relates the deformed configuration with the undeformed configuration.

It is convenient to do the analysis of deformation or motion of a continuum body in terms of the displacement field, In general, the displacement field is expressed in terms of the material coordinates as

An example of a double displacement reaction is the reaction of lead ( II ) nitrate with potassium iodide to form lead ( II ) iodide and potassium nitrate:

The basic principle of displacement chromatography is:

Impact-crater formation is therefore more closely analogous to cratering by high explosives than by mechanical displacement.
