Influence of surface sealing on color stability and roughness of composite submitted to ultraviolet-accelerated aging
(Wiley-Blackwell, 2017-05-01)
Aim: In the present study, we evaluated the influence of surface sealing on color stability and surface roughness of a composite resin after accelerated artificial aging. Methods: Thirty-two specimens of a composite were ...
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 ...
Vortex state in a mesoscopic flat disk with rough surface
(Elsevier B.V., 2012-09-01)
In this paper we study some superconducting properties of a flat disk by taking into account the roughness of the surface. Also, the sample is surrounded by a thin layer of a metallic material and submitted to and external ...
Impact of surface roughness on the self-assembling of molecular films onto gold electrodes for label-free biosensing applications
(2021-05-10)
The properties of molecular films assembled over gold electrode surfaces are prone to reflect fabrication characteristics. Here we show the importance of controlling electrode surface characteristics of a gold interface ...

(Informa Healthcare, 2015-04-01)
Objective. This study aimed to investigate the surface roughness of composite resins subjected to thermal cycles procedure. Materials and methods. Two microfill, four microhybrid and four nanofill composites were used. The ...
Weight loss and changes in surface roughness of denture base and reline materials after simulated toothbrushing in vitro
(Wiley-Blackwell, 2012-06-01)
Objective: To evaluate the weight loss and the surface roughness of acrylic resins after simulated brushing tests.Material and methods: Ten specimens of each material (Tokuyama Rebase II-TR, New Truliner-NT, Ufi Gel Hard-UH ...
Artificial neural networks for machining processes surface roughness modeling
(Springer London Ltd, 2010-08-01)
In recent years, several papers on machining processes have focused on the use of artificial neural networks for modeling surface roughness. Even in such a specific niche of engineering literature, the papers differ ...
Multiscale Analysis of Topographic Surface Roughness in the Midland Valley, Scotland
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
Surface roughness is an important geomorphological variable which has been used in the Earth and planetary sciences to infer material properties, current/past processes, and the time elapsed since formation. No single ...
