The effect of groove texture patterns on piston-ring pack friction
TL;DR: In this article, a numerical model was developed to investigate the effects of groove characteristics on the lubrication condition and friction at the interface between the piston ring and cylinder liners, and the model aims to solve the average Reynolds equation, which depends on the real surface topographies of the cylinder liner.

Characterization of concrete surface roughness and its relation to adhesion in repair systems
TL;DR: In this article, the relationship between surface geometry and adhesion in repair systems is analyzed using four measurement techniques, corresponding to different levels of observation: laser, mechanical profilometry, a microscopic method and a "sand" (macroscopic) method.

Claudiu Giusca,Claudiu Giusca,Richard Leach,Franck Helary,Tadas Gutauskas,Lakshmi Nimishakavi +5 more
TL;DR: This paper first introduces the international standards framework and then present current methods based on averaging and subtraction to isolate the measurement noise and residual flatness from the sample surface topography.

Template matching using the parametric template vector with translation, rotation and scale invariance
Yi-Hsien Lin,Chin-Hsing Chen +1 more
TL;DR: Experiments with Gaussian noise demonstrate that the proposed algorithm is robust to detect the target object with the changes of translation, orientation and scale, and is suitable for on-line template matching with scene translation, rotation and scaling.

Tribological characteristics of one-process and two-process cylinder liner honed surfaces under reciprocating sliding conditions
TL;DR: In this paper, the effect of surface texture on cylinder liners wear was investigated on a reciprocating tester and it was found that wear of two-process surfaces was lower than that of one process surfaces characterized by the same Sq parameter.
