Front-back confusions when sources and listeners rotate

Journal of the Acoustical Society of America, 2015
Tonal stimuli presented from directly in-front or directly in-back of a stationary listener are often miss-located in that sounds presented from in-front are occasionally perceived as being in-back of the listener; and often sounds presented in-back of a listener are perceived as being in-front.

Suppressing Convective Instabilities in Propagating Fronts by Tube Rotation

The Journal of Physical Chemistry, 1996
Density gradients caused by thermal and solutal gradients often cause double-diffusive and/or Taylor instabilities in propagating fronts. These instabilities manifest themselves as “fingering” that can affect the front shape and velocity and, in extreme cases, destroy the front.

[Rotated-chipping phacoemulsification in front of capsule].

[Zhonghua yan ke za zhi] Chinese journal of ophthalmology, 2003
The study was designed to investigate the clinical effects of rotated-chipping phacoemulsification in front of capsule.Phacoemulsification using rotated-chipping technique in front of capsule with intraocular lens implantation was performed with medium energy and high vacuum on 50 eyes.Rotated-chipping technique was successfully completed in 46 of 50 ...

Multiseed stimulated rotational Raman scattering for wave-front control

Journal of the Optical Society of America B, 1991
We apply a new technique, multiseed stimulated rotational Raman scattering, to the wave-front control of Raman-converted light when the Raman gain–length product is large enough to produce significant conversion beyond the first-Stokes order. For rotational Raman scattering, such as that which dominates in atmospheric propagation, the polarizations of ...

Does the Earth's rotation influence the location of the shelf sea fronts?

Journal of Geophysical Research: Oceans, 1994
Two alternative hypotheses which attempt to explain the position of the shelf sea fronts are (1) control by the energetics of tidal and wind mixing and (2) limitation of the penetration of tidal stresses by the effects of rotation. A turbulence‐closure (T/C) point model has been used to investigate the interaction of these two constraints and predict ...

Time-varying stiffness analysis on rotating shaft with elliptical-front crack

International Journal of Industrial and Systems Engineering, 2014
The aim of this paper is to investigate the difference of time-varying stiffness characteristics between a semi-elliptical front crack and a straight front crack of shaft-element in order to obtain a more accurate and realistic cracked-rotor model for rotating machinery system.

On rotating plane-fronted waves and their Poincaré-invariant differential geometry

Journal of Mathematical Physics, 1979
After reviewing the rotating plane-fronted wave type solutions of the scalar wave equation and Maxwell’s vacuum equations in flat space (we point out that there are Yang–Mill analogs as well), we study their Poincaré-invariant geometry by discussing their characteristic differential invariants and a noninertial curvilinear coordinate system canonically

On a front between two rotating flows with application to the Flores Sea

Dynamics of Atmospheres and Oceans, 1982
Abstract The horizontal shape of the front between two water masses, which subcritically approach each other from different sides of a wedge of land, is considered using a simple model. It is shown that the angle of the wedge of land is critical to the behaviour of the solution and that for a finite Bernoulli head difference between the flows, no ...

Rotation dependent ion fluxes in front of resonant magnetic perturbation coils

Nuclear Fusion, 2012
Abstract Ion fluxes to the first wall of TEXTOR are modulated during application of a fast rotating resonant magnetic perturbation (RMP) field. The modulation in front of the RMP coils matches the magnetic topology modelled in vacuum approximation for low relative rotation of f rel = −0.2 kHz between the RMP field and ...

A model of rotating convective rolls in water over a freezing front

Journal of Crystal Growth, 1981
Abstract A model of unsteady convective flows ahead of a moving ice-water interface is suggested. It explains the formation of helical clouds in ice during the freezing of water that contains impurities.
