Correlation method of processing the image of the surface microrelief to determine its roughness
Физика волновых процессов и радиотехнические системыBackground. The analysis of the results of the use of various machines and mechanisms in the national economy has shown that the roughness of the microrelief of their working surfaces largely determines the reliability and durability of their operation ...

Assessing soil surface roughness decay during simulated rainfall by multifractal analysis [PDF]
Nonlinear Processes in Geophysics, 2008 Understanding and describing the spatial characteristics of soil surface microrelief are required for modelling overland flow and erosion. We employed the multifractal approach to characterize topographical point elevation data sets acquired by high ...

Microrelief Associated with Gas Emission Craters: Remote-Sensing and Field-Based Study
Remote Sensing, 2018 Formation of gas emission craters (GEC) is a new process in the permafrost zone, leading to considerable terrain changes. Yet their role in changing the relief is local, incomparable in the volume of the removed deposits to other destructive cryogenic ...

Resistance of Overland Flow on Complex Microrelief [PDF]
AIP Conference Proceedings, 2011 Resistance problem of the overland flow on complex microrelief is intricated. The difficulty in evaluating the resistance mainly comes from the variety of flow status and the complex composition of the resistance. Finding out the correlation between resistance components and influence factors is believed valuable to this problem.

Determining Optimal Parameters of Regular Microrelief Formed on the End Surfaces of Rotary Bodies
Algorithms, 2021 The analytical dependences for determining the overlap area of V-shaped grooves of partially regular microrelief shifted by an angular pitch of 0.5° are established. The V-shaped grooves are formed on the end surface of the rotary body by vibration.
