Rotation around the vertical pivot axis is called rotation.

Supercells and tornadoes rotate cyclonically in numerical simulations even when the Coriolis effect is neglected .< ref name =" Origin of Updraft Rotation in Supercells ">< ref name =" Rotation and Propagation of Simulated Supercells "> Low-level mesocyclones and tornadoes owe their rotation to complex processes within the supercell and ambient environment .< ref name =" Tornado Development and Decay within a Supercell ">

Kerr Rotation is a rotation in the angle of transmitted light, and Kerr Ellipticity is the ratio of the major to minor axis of the ellipse traced out by elliptically polarized light on the plane through which it propagates.

A change in Kerr Rotation is most easily recognized in linearly polarized light, which can be separated into two Circularly polarized components: Left-Handed Circular Polarized ( LCP ) light and Right-Handed Circular Polarized ( RCP ) light.

The longer " true " sidereal period is called a stellar day by the International Earth Rotation and Reference Systems Service ( IERS ).

The IERS Reference Meridian ( IRM ), also called the International Reference Meridian, is the reference meridian used as the prime meridian ( 0 ° longitude ) by the International Earth Rotation and Reference Systems Service ( IERS ).

Rotation matrices depend on the axis around which a point is to be rotated.

Rotation is inward and counterclockwise in the northern hemisphere as opposed to inward and clockwise in the southern hemisphere due to the coriolis force.

Rotation of ammunition is a term used with reference to guns.

The International Earth Rotation and Reference Systems Service ( IERS ), formerly the International Earth Rotation Service, is the body responsible for maintaining global time and reference frame standards, notably through its Earth Orientation Parameter ( EOP ) and International Celestial Reference System ( ICRS ) groups.

Rotation causes a distortion from this spherical shape ; a common measure of the distortion is the flattening ( sometimes called ellipticity or oblateness ), which can depend on a variety of factors including the size, angular velocity, density, and elasticity.

Rotation of a planet causes it to approximate an oblate ellipsoid / spheroid with a bulge at the equator and flattening at the North and South Poles, so that the equatorial radius is larger than the polar radius by approximately where the oblateness constant is

Monitoring of the polar motion is now done by the International Earth Rotation Service.

Job Rotation is also believed to have the ability to decrease the amount of boredom and monotony experienced by employees who work the same position for extended periods of time.

Rotation in the outer core is supplied by the Coriolis effect caused by the rotation of the Earth.

Finally, the utilization of Job Rotation may have the effect of reducing a workforce because of the cross-training involved ; a company may not need to hire additional staff to cover positions and may possibly layoff current employees no longer considered necessary.

Kerr Rotation and Kerr Ellipticity are changes in the polarization of incident light which comes in contact with a gyromagnetic material.

The observations allow the determination of a measure of the Earth's angle with respect to the ICRF, called the Earth Rotation Angle ( ERA, which serves as a modern replacement for Greenwich Mean Sidereal Time ).

Rotation of the head causes a flow of fluid, which in turn causes displacement of the top portion of the hair cells that are embedded in the jelly-like cupula.

The organization was formerly known as International Earth Rotation Service until 2003 when it formally changed its name to its present form, in which the organization chose to retain the acronym IERS.

Rotation of the servo in the other direction causes torque to be applied to a linkage and cam which causes friction with the braking material.

Rotation of the head causes a flow of fluid, which in turn causes displacement of the top portion of the hair cells that are embedded in the jelly-like cupula.

The reflected light has a change in Kerr Rotation and Kerr Ellipticity which is measured by an analyzer and corresponds to either a logical 0 or 1.

* Treatise on the Rectilinear Motion and Rotation of Bodies ( Cambridge, 1784 ), which gives some interesting experiments, by means of which mechanical truths can be ocularly exhibited and demonstrated, and describes the machine, since named after Atwood, for verifying experimentally the laws of simple acceleration of motion.

Rotation raises or lowers the tension hoop relative to the rim, which increases or decreases the pitch of the drum by increasing or decreasing the tension of the drum head.

* Rotation forest-in which every decision tree is trained by first applying principal component analysis ( PCA ) on a random subset of the input features.

The SVD decomposes M into three simple transformations: a Rotation matrix | rotation V < sup >*</ sup >, a scaling ( geometry ) | scaling Σ along the rotated coordinate axes and a second rotation U. Σ is a diagonal matrix containing in its diagonal the singular values of M, which represent the lengths σ < sub > 1 </ sub > and σ < sub > 2 </ sub > of the Ellipse # Elements of an ellipse | semi-axes of the ellipse.

The International Earth Rotation and Reference Systems Service ( IERS ) specifies both years to 12 significant digits by referring to an article which specifies both in terms of a Julian millennium of 1000 Julian years.

In 2007 seven members of the RCH were deployed to Afghanistan as part of Joint Task Force Afghanistan ( JTF AFG ) Rotation 4, which included approximately 2330 Canadian Forces members from the Quebec region.

Besides his masterpiece, he wrote L ' Art défensif supérieur à l ' offensif ( 1793 ; in reply to attacks made upon his earliest work, La Fortification perpendiculaire, of which in later editions it forms part ); Mémoire historique sur la fonte des canons ( Paris, 1758 ), and other works on the same subject ; ( London, 1777 ); Rotation des boulets ( Acad., 1755 ); and Relations du siège de Saint-Jean-d ' Acre ( Paris, 1789 ).
