Surface roughness measurement by means of speckle wavelength decorrelation
M. Giglio,S. Musazzi,U. Perini +2 more
TL;DR: In this article, the authors exploit speckle wavelength decorrelation techniques for the characterization of surface roughness up to a few microns, using an argon laser, a grating, two photodetectors, and a commercial cross correlator.

Digital Terrain Modeling and Industrial Surface Metrology: Converging Realms
TL;DR: In this article, the authors introduce industrial surface metrology, examines the field in the context of terrain modeling a.k.a. surface topography of manufactured components, exemplified by automobile-engine cylinders, is routinely modeled by variogram analysis, relief shading, and most other techniques of parameterization and visualization familiar to geography.

Interdependence of Amplitude Roughness Parameters on Rough Gaussian Surfaces
TL;DR: The numerical analysis of 17 standardized amplitude roughness parameters collected from 90000 computer-generated rough surfaces revealed so far undetected interdependencies among some of these parameters, namely the results show a strong linear relation between 12 amplituderoughness parameters.

Nano-metrology and terrain modelling - convergent practice in surface characterisation
TL;DR: In this paper, the authors introduce terrain modelling, discuss its similarities to and differences from industrial surface metrology, and raise the possibility of a unified discipline of quantitative surface characterisation, and exemplify a multivariate statistical procedure that may transfer to tribological applications of 3-D metrological height data.

Characteristic contact angles in the Aluminium/vitreous carbon system
TL;DR: In this paper, the authors identify the characteristic contact angles in the Al/C system at temperatures below 1,073 K and at temperatures above 1,273 K. This is the case for polycrystalline graphite substrates which are difficult to polish.

Measuring channel and gully cross-sections with an airborne laser altimeter
TL;DR: In this article, a laser altimeter, making 4000 measurements per second, was used to measure channel and gully morphology, and the laser measurements provided quick, accurate and readily obtained data on the cross-section and morphology of channels and gullies in relation to the adjacent landscape.

Application of Probability and Entropy Concepts in Pipe‐Flow Study
TL;DR: In this article, a new velocity distribution equation based on probability and entropy concepts is proposed as an alternative to the existing power law and universal law equations for pipeflow studies with only two parameters, which can represent the velocity distribution in the entire flow field in a pipe, regardless of whether the flow is laminar or turbulent.
