Comparison of undulation difference accuracies using gravity anomalies and gravity disturbances
Bulletin Géodésique, 1980Errors in the outer zone contribution to oceanic undulation differences computed from a finite set of potential coefficients based on satellite measurements of gravity anomalies and gravity disturbances are analyzed. Equations are derived for the truncation errors resulting from the lack of high-degree coefficients and the commission errors arising ...

Mechanical Stabilization in Robotic Bionic Eyes with Gravity and Disturbance Compensations
2019 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2019The vibration of the robot during the movement brings various irregular motion disturbances to the robot’s head, these vibration results into unstable images captures by the head-mounted vision system and therefor the vision system cannot accurately perceive the environment.

Capillary gravity waves caused by a moving disturbance: Wave resistance
Physical Review E, 1996The dispersive property of capillary gravity waves is responsible for the complicated wave pattern generated at the free surface of a calm liquid by a disturbance moving with a velocity V greater than the minimum phase speed ${\mathit{c}}^{\mathrm{min}}$=(4g\ensuremath{\gamma}/\ensuremath{\rho}${)}^{1/4}$ (\ensuremath{\rho} is the liquid density ...

Contributions to geophysics & geodesy: a journal of geophysics, geodesy, meteorology and climatology, 2004
Four types of topographical corrections to gravity disturbance (to actual gravity) are investigated, distinguished by the density (real or constant-model) and by the lower boundary (geoid or reference ellipsoid) of the topographical masses. Each type produces a specific "topo-corrected gravity disturbance", referred to as "NT", "NTC", "NET", and "NETC".

Nonaxisymmetric disturbances in compound liquid jets falling under gravity
Physical Review E, 2016The disintegration of a compound thread of fluid can be utilized in a wide variety of applications including the production of compound droplets or capsules. In this paper we investigate the linear instability of a compound inviscid liquid jet falling under gravity in a surrounding gas with respect to nonaxisymmetric waves.

Rotational disturbance in laser-interferometric gravity gradiometry
Physica ScriptaAbstract Laser interferometers have been used for precise measurements of gravity and related effects. These include experiments to search for a fifth force and absolute ballistic gravimeters, which use a Michelson-type laser interferometer to measure the acceleration of a free-falling test mass.

Generation of internal gravity waves by vortex disturbances in a shear flow
Izvestiya, Atmospheric and Oceanic Physics, 2014A mechanism of internal gravity wave generation by eddy perturbations in a horizontal flow with a vertical shear has been investigated. It is assumed that a shear flow is localized in the atmospheric boundary layer with neutral stratification, over which there is a semibounded stratified layer moving at a constant velocity.

Integral formulas are derived for the determination of geopotential coefficients from gravity anomalies and gravity disturbances over the surface of the Earth. First order topographic corrections to spherical formulas are presented. In addition new integral formulas are derived for the determination of the external gravity field from surface gravity.
