Surface roughening, surface melting and crystal quality
Faraday Discussions, 1993The modelling of crystal surfaces, both in equilibrium and during growth, is now at a stage where the relation between surface structure and crystal quality are accessible for future studies. The classical point of view is that the roughening transition marks the transition from step growth to rough growth with qualitative changes in the growth rate ...

Surface quality assessment of subdivision surfaces on programmable graphics hardware
Proceedings Shape Modeling Applications, 2004., 2004We propose a method of subdivision surface quality assessment by reflection lines on programmable graphics hardware (GPU). Using reflection lines is effective for surface quality assessment because the shapes of these lines are changed according to a slight variance of surface shapes.

Meaningful Surface Roughness and Quality Tolerances
International Optical Design Conference and Optical Fabrication and Testing, 2010Meaningful surface quality and roughness tolerances can be derived based on physics and requirements rather than history and inertia. This paper describes how to develop such specifications for these annoying parameters.

Surface Water Quality Assessment by Environmetric Methods
Environmental Monitoring and Assessment, 2006This environmetric study deals with the interpretation of river water monitoring data from the basin of the Buyuk Menderes River and its tributaries in Turkey. Eleven variables were measured to estimate water quality at 17 sampling sites. Factor analysis was applied to explain the correlations between the observations in terms of underlying factors ...

SURFACE ENGINEERING: PROVING THE QUALITY
Surface Engineering, 1993Surface engineering is an enabling technology which can provide specialist surface properties while preserving the important structural features of the substrate. It can also save energy, reduce wear and corrosion, and, importantly, conserve rare materials by localising specialist properties at the surface rather than their needing to obtain ...

Quality of the Surface Waters in the Parma Valley of Italy
International Journal of Environmental Studies, 1987Over the last three decades, the quality of the Val Parma water courses has undergone a drastic deterioration that can be linked to industrial and demographic transformation which have occurred there. From 1951 to 1981 there was a 360% increase in the pollution load by human activities with most of that increase occurring between 1961 and 1971. In 1976
