Differences Between Effective and Physical Roughness Parameter- A Headwater Mountain River Experiment
(IEEE, 2021)
One-dimensional hydrodynamic models (HM) are widely used in the hydraulic modeling of rivers and channels. The result obtained with this type of model depends largely on correct estimation the roughness parameter. The value ...
Effect of thermocycling on roughness of nanofill, microfill and microhybrid composites
(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 ...
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 THE SURFACE ROUGHNESS OF PARTICLEBOARDS AND THEIR PERFORMANCE TOWARDS COATING
(Universidad del Bío-Bío, 2010)
Effect of thermal and mechanical cycles on the hardness and roughness of artificial teeth
(2015)
In this study the effects of thermal and mechanical cycles on the hardness and roughness of artificial teeth were evaluated. Materials and Methods:Specimens were prepared and stored in distilled water at 37ºC for 48 hours ...
On the effect of the refinement of the roughness description in a 2D approach for a mountain river: A case study
(2021)
The prediction of water levels in rivers is important to prevent economical as well as human losses caused by flooding.
Hydraulic models are commonly used to predict those water levels and take actions to mitigate flooding ...
Interface roughness effects on coercivity and exchange bias
(Journal of Applied Physics, 2005)
Effects of different polishing procedures on the surface roughness and hardness of polyether ether ketone (PEEK)
(Facultad de Odontología. Universidad de Costa Rica, 2021)
