Effects of different polishing procedures on the surface roughness and hardness of polyether ether ketone (PEEK)
(Facultad de Odontología. Universidad de Costa Rica, 2021)
Roughness measurement of paper using speckle
(2011-09-02)
We present a method of measure of the roughness of the paper based on the analysis of a speckle pattern on the surface. Images of speckle over the surface of paper are captured by means of a simple configuration using a ...
Superficial effects of different finishing and polishing systems on the surface roughness and color change of resin-based CAD/CAM Blocks
(Facultad de Odontología. Universidad de Costa Rica, 2021)
Influence of the sign of the refractive index in the reflectivity of a metamaterial surface with localized roughness
(Springer, 2011-06)
To study the scattering properties of metamaterials, we generalize two scattering methods developed for conventional (non-magnetic) isotropic materials to the case of materials with arbitrary values (positive or negative) ...
Effect of concurrent geometry and roughness in interacting surfaces
(American Physical Society, 2015-02)
We study the interaction energy between two surfaces, one of them flat, the other describable as the composition of a small-amplitude roughness and a slightly curved, smooth surface. The roughness, represented by a spatially ...
Influence of roughness on the tribological behavior of a steel- steel couple lubricated with thread compound
(Planta Piloto de Ingeniería Química, 2019-07-31)
The purpose of this study is to determinate the influence of surface roughness on the tribological behavior of a lubricated steel against steel tribosystem. Tests were carried out at high pressure and slow sliding speed, ...
Effects of whitening dentifrices on the enamel color, surface roughness, and morphology
(Facultad de Odontología. Universidad de Costa Rica, 2023)
Degradation of the soil surface roughness by rainfall in two loess soils
(Elsevier Science, 2011-08)
The soil surface roughness is one of the main factors affecting wind erosion. Little is known about the influence of rains on the degradation rate of the soil surface roughness in different tillage systems and soil types. ...
Effect of Different Denture Base Cleansers on Surface Roughness of Heat Polymerised Acrylic Materials with Different Curing Process
(Facultad de Odontología. Universidad de Costa Rica, 2020)
