ANALYSIS OF SURFACE ROUGHNESS OF BLACK ALDER AS FUNCTION OF VARIOUS PROCESSING PARAMETERS [PDF]

open access: greenPro Ligno, 2012
The objective of this study was to analyse thesurface quality of black alder (Alnus glutinosa)samples as function of sanding processes based onfour grits sizes, namely 60, 80, 100 and 120. Thesanding process was performed parallel,perpendicular and at 45

Fractal model of shear-induced rough fracture flow by cross-scale description of its geometry

open access: yes矿业科学学报, 2023
The Beishan area in Gansu province is the main pre-selected site for deep geological disposal of high-level radioactive waste, it therefore bears implications for the study of fracture seepage characteristics of granite caused by shear failure.

New measuring method for single pitch deviation of hobbed gears (Using measured helix form data conditioned with Gaussian filter)

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Improving quality of hobbed gears must yield high accuracy of ground gears. This can be achieved by measuring hobbed gears accurately. Pitch deviations are most crucial in grinding processes with a worm type grinder.

Influence of self-affine roughness on Parsons-Zobel plots for electrical double layers [PDF]

open access: yes, 2004
In this paper we investigate the dependence of Parsons-Zobel plots on characteristic self-affine roughness parameters of the metal electrode in electrical double layers. Among the roughness amplitude w, the correlation length ξ, and roughness exponent H,
