For this reason, there is an urge towards the characterization of surface roughness only on the top topography of pavements, still representing roughness at different length scales. Ueckermann et al. [17] used summit profile PSD in order to exclude the surface cavities of the pavement. However,...
The lake model with default parameters presented significant negative bias during the day and positive bias during the night on lake surface temperature. Calibrations of water absorption and extinction coefficients, surface roughness length, and eddy diffusion coefficient were carried out to correct this...
Nk is the cumulative number of tubes (i.e., pores) with diameters no smaller than a certain tube (i.e., pore) diameter k, kmax is the maximal tube diameter, Lo is the sample length along the direction of fluid flow, and Df and DT are the pore-area and tor- tuosity fractal dimen...
surface roughness as well as local composition and pre-existing defects has to be taken into account34. For the solving bonding of COC advantage is taken of the polymers solubility in Cyclohexane to reach entanglement of polymer chains on the bonding surface. Through the solvation, the polymer ch...
(Manuscript received 6 July 2000, in final form 21 February 2001) ABSTRACT Roughness height for heat transfer is a crucial parameter in estimation of heat transfer between the land surface and the atmosphere. Although many empirical formulations have been proposed over the past fewdecades, the ...
surface roughness to attain bond strength in concrete. The containment of straight wire steel fiber within the shear crack predominantly relies on the fiber length to establish adequate bond strength before potential pullout from the concrete28,54. Given its lower fiber bond factor, the use of ...
The thickness variation, lathe check depth, length and surface roughness of rubberwood veneers increased with increasing veneer thickness, whereas lathe check frequency decreased with increasing veneer thickness. In general, veneer thickness has more prominent effects on the properties of rubberwood veneer...
Taking three different tillage methods of farmland as the research object, the surface root mean square height (RMSH), correlation length (CL), and their ratio were selected as roughness parameters to explore the anisotropy of microtopography features in different directions. The measurement method ...
A knife with a blade angle of 2.5° was employed for the cutting test, extending the entire length along the sample diameter (see Fig. 1). The cutting was executed with a knife and measuring the head speed of 5 mm s−1. Maximum cutting force values were recorded during the test and...
