Analysis of surface roughness of glass-ionomer cements and compomer
(Blackwell Publishing, 2003-07-01)
The purpose of this study was to evaluate the surface roughness of two glass-ionomer cements (Vitremer and Chelon-Fil), and one compomer (Dyract) when submitted to different finishing/polishing procedures at different ...
Scale-sensitive Fractal Analysis of the Surface Roughness of Bloomed Chocolate
(WILEY, 2006)
The surface roughness of stored chocolate bars was studied by scanning laser microscopy and area-scale fractal analysis. Topographic data were expressed by the statistical average roughness (Sa), by two parameters from ...

Roughness and surface material effects on nucleate boiling heat transfer from cylindrical surfaces to refrigerants R-134a and R-123
(ELSEVIER SCIENCE INC, 2009)
This paper presents results of an experimental investigation carried out to determine the effects of the surface roughness of different materials on nucleate boiling heat transfer of refrigerants R-134a and R-123. Experiments ...
Development of a new Lagrangian vortex method for evaluating effects of surfaces roughness
(2019-03-01)
The main contribution of this paper is to develop a new methodology to include effects of surface roughness on aerodynamic of bodies. The numerical approach simulates the mechanism of vortex shedding of a rough circular ...
Um novo método para avaliar os coeficientes de rugosidade e áreas de vale de superfícies adquiridas por scanner a laser
(Universidade do Vale do Rio dos Sinos, 2021-05-05)
Quality evaluation of a material’s surface is performed through roughness analysis of surface samples. Several techniques have been presented to achieve this goal, including geometrical analysis and surface roughness ...

Impact of rough potentials in rocked ratchet performance
(Elsevier B.V., 2018)
We consider thermal ratchets modeled by overdamped Brownian motion in a spatially periodic potential with a tilting process, both unbiased on average. We investigate the impact of the introduction of roughness in the ...
