Curvature sensor for the measurement of the static corneal topography and the dynamic tear film topography in the human eye [PDF]

open access: yes, 2005
A system to measure the topography of the first optical surface of the human eye noninvasively by using a curvature sensor is described. The static corneal topography and the dynamic topography of the tear film can both be measured, and the topographies ...

A flank modification method for spiral bevel gears based on mismatch topography adjustment

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
In order to improve the meshing performance or correct contact area of spiral bevel gears, a new method of tooth surface topography modification is proposed in this paper.

Statistical representation of mountain shading [PDF]

open access: yes, 2004
International audienceShadows cast by the mountains themselves have a strong influence on the surface energy balance of mountainous regions. If the influence of shadows is to be included on sub-grid scales in a surface energy balance model, a statistical

Effects of Topography on Seismic-Wave Propagation: An Example from Northern Taiwan [PDF]

open access: yes, 2009
Topography influences ground motion and, in general, increases the amplitude of shaking at mountain tops and ridges, whereas valleys have reduced ground motions, as is observed from data recorded during and after real earthquakes and from numerical ...

On the More Complex Wavelength Dependency of Airy Isostasy in Icy Shells of Ocean Worlds

open access: yesGeophysical Research Letters, 2023
The topography of ocean worlds is often used to infer ice shell thicknesses by assuming topography is compensated by a basal root. We systematically test the stability of isostatically compensated topography in ice shells. At short horizontal wavelengths,

An Experimental Investigation of Steel Surface Topography Transfer by Cold Rolling

open access: yesMicromachines, 2020
Automobile and household appliance panels require steel strips with extremely high-quality surfaces. Therefore, an in-depth study of the surface topography transfer of the steel strip during the rolling process is of considerable significance for ...

Flow of evaporating, gravity-driven thin liquid films over topography [PDF]

open access: yes, 2006
The effect of topography on the free surface and solvent concentration profiles of an evaporating thin film of liquid flowing down an inclined plane is considered.

Greenland Ice Sheet Surface Topography and Drainage Structure Controlled by the Transfer of Basal Variability

open access: yesFrontiers in Earth Science, 2018
Ice flow can transfer variations in basal topography and basal slipperiness to the ice surface. Recent developments in this theory have made it possible to conduct numerical experiments to predict mesoscale surface topographical undulations and surface ...

Efficient Image-Space Extraction and Representation of 3D Surface Topography

open access: yes, 2015
Surface topography refers to the geometric micro-structure of a surface and defines its tactile characteristics (typically in the sub-millimeter range).

Imaging Pulsed Laser Deposition oxide growth by in-situ Atomic Force Microscopy [PDF]

open access: yes, 2017
To visualize the topography of thin oxide films during growth, thereby enabling to study its growth behavior quasi real-time, we have designed and integrated an atomic force microscope (AFM) in a pulsed laser deposition (PLD) vacuum setup.
