Dynamic evolution of interface roughness during friction and wear processes [PDF]

, 2014
Dynamic evolution of surface roughness and influence of initial roughness (Sa=0.282 to 6.73 µm) during friction and wear processes has been analyzed experimentally.

Surface roughness of Baltic sea ice [PDF]

Journal of Geophysical Research: Oceans, 1997
Small‐, medium‐, and large‐scale measurements of sea ice surface roughness were carried out in the Baltic Sea over a 3‐year period. A clear relationship was found between the rms height and correlation length of Baltic sea ice. In most cases the surface correlation function was close to exponential.

Towards Control of Autonomous Surface Vehicles in Rough Seas

IFAC-PapersOnLine, 2020
Abstract This paper addresses the problem of controlling an Autonomous Surface Vehicle (ASV) in rough sea-states, with a view towards minimising wave-induced forces, whilst maintaining headway. This is a challenging control application since, and as is derived in the paper, the interaction between the vessel and the wave disturbance is nonlinear and ...

Impact of the surface roughness on the electrical capacitance [PDF]

, 2006
A new hybrid approach consists to use the advantages of both systems namely the high geometric aspects of the electrodes of the ultracapacitor and the high dielectric strength of polymer materials used in dielectric capacitors.

An Improved Semi-Empirical Model for Radar Backscattering from Rough Sea Surfaces at X-Band [PDF]

Journal of the Korean Institute of Electromagnetic Engineering and Science, 2018
We propose an improved semi-empirical scattering model for X-band radar backscattering from rough sea surfaces. This new model has a wider validity range of wind speeds than does the existing semi-empirical sea spectrum (SESS) model.

Surface roughness of Titan's hydrocarbon seas

Earth and Planetary Science Letters, 2017
Abstract We derive fields of solutions for the surface properties (roughness and permittivity) of the liquid hydrocarbon bodies Ligeia, Kraken and Punga Mare on Titan by applying the Radar Statistical Reconnaissance (RSR) technique to the Cassini RADAR observations in altimeter mode during the northern early summer. At the time of observation, Kraken

Analysis of surface roughness in relation to soil loss and runoff at high rainfall intensities. [PDF]

, 2002
The decay of roughness is an important factor governing surface processes such as infiltration and soil erosion. Thus the decay of surface roughness under different surface conditions was investigated and related to quantitative amounts of soil loss ...

Arctic Sea Ice Surface Roughness Estimated from Multi-Angular Reflectance Satellite Imagery

Remote Sensing, 2018
Sea ice surface roughness affects ice-atmosphere interactions, serves as an indicator of ice age, shows patterns of ice convergence and divergence, affects the spatial extent of summer meltponds, and affects ice albedo.

Mapping Arctic Sea-Ice Surface Roughness with Multi-Angle Imaging SpectroRadiometer

Remote Sensing, 2022
Sea-ice surface roughness (SIR) is a crucial parameter in climate and oceanographic studies, constraining momentum transfer between the atmosphere and ocean, providing preconditioning for summer-melt pond extent, and being related to ice age and ...
