The macroscopic relative motion solid-liquid interface widely exists in the contact motion pairs of machine tools and other mechanical equipment. In order to accurately obtain the tangential contact stiffness and damping parameters, the Savkoor asperity ...

Tangential Velocity Measurement Using Interferometric MTI Radar [PDF]
An Interferometric Moving Target Indicator radar can be used to measure the tangential velocity component of a moving target. Multiple baselines, along with the conventional radial velocity measurement, allow estimating the true 3-D velocity vector of a target.

Effects of Tangential Velocity in the Reactive Relativistic Riemann Problem [PDF]
Abstract Type I X-ray bursts are thermonuclear burning events that occur on the surfaces of accreting neutron stars. Burning begins in a localized spot in the star’s ocean layer before propagating across the entire surface as a deflagration. On the scale of the entire star, the burning front can be thought of as discontinuity.

MEAN-LINE FLOW MODEL OF VISCOUS LIQUIDS IN A VORTEX PUMP
The axial, radial and tangential velocity profiles of six fluids were extracted from computational fluid dynamics simulation results at points in a pump chamber 1 mm distant from the blades in a vortex pump at the specific speed of 76.

Experimental investigation on free surface vortices driven by tangential inlets [PDF]
Particle Image Velocimetry (PIV) measurements have been carried out in order to analyze the structure of free surface vortices in a promoting geometry with two tangential inlets. Velocity fields associated to the free surface vortex have been obtained at

Perceptual judgments of duration of parabolic motions
In a 2-alternative forced-choice protocol, observers judged the duration of ball motions shown on an immersive virtual-reality display as approaching in the sagittal plane along parabolic trajectories compatible with Earth gravity effects.

TANGENTIAL VELOCITY OF THE DARK MATTER IN THE BULLET CLUSTER FROM PRECISE LENSED IMAGE REDSHIFTS [PDF]
We show that the fast-moving component of the “Bullet Cluster” (1E0657-56) can induce potentially resolvable redshift differences between multiply lensed images of background galaxies.

Galactic rotation curves in modified gravity with non-minimal coupling between matter and geometry [PDF]
We investigate the possibility that the behavior of the rotational velocities of test particles gravitating around galaxies can be explained in the framework of modified gravity models with non-minimal matter-geometry coupling. Generally, the dynamics of

The Tangential Velocity Estimation Algorithm for Space-borne SAR
Abstract This article presents a discussion of one of the important areas of application of synthetic aperture radars (SAR) – the moving target indication (MTI) mode. The principle of trajectory signal processing in MTI systems is based on the estimation of the Doppler frequency or phase shift of the echo signals due to the movement of ...
