Kinect cloud normals: towards surface orientation estimation
… multitude of scenes and an approach to determine surface normals from these images. The goal of this endeavor is to provide a dataset of RGB images and surface normal estimates for each image so that the latter may serve as the ground truth for both training and evaluation of algorithms estimating …

Surface Orientation Dependent Corrosion Damage and Temperature Dependent Mechanical Property Degradation of Sensitized AA5083-H116 Alloys
… levels. Accelerated corrosion on different surface orientations led to different corrosion mechanisms (parallel IGC vs. perpendicular IGC). While 5083-H116 material corroded on the rolled surface led to a uniform exfoliation damage on 150°C sensitization exposure, the 100°C rolled surface …

An investigation of the surface finishing action and resulting surfaces produced by the Cascade Finishing process
… Process with respect to its ability to improve surface finish. Although mainly used to deburr and clean castings and machined parts, the process was able to greatly improve the surface finish under the right operating conditions. Six major topics were investigated: The nature of the surface …

Single- and few-layer graphene by ambient pressure chemical vapor deposition on nickel
… and the graphene can be transferred from the Ni surface to dielectric substrates in order to integrate them to graphene device prototypes. Uniform single layer graphene can be grown with the same process by using single crystalline Ni with a (111) surface orientation. Raman spectroscopy and …

A study of fast, robust stereo-matching algorithms
… window to locally deform according to the surface orientation of the imaged point. The algorithm then performs correlation in multiple dimensions to simultaneously determine the most probable depth and tilt. The 2D surface orientation search may be made more efficient and robust by …

Higher order asymptotic inference in remote sensing of oceanic and planetary environments
… consider the problems of (1) planetary terrain surface slope estimation, (2) Lambertian surface orientation and albedo resolution and (3) passive source localization in a fluctuating waveguide containing random internal waves. In these and other applications, measurements are typically corrupted …

STM Studies of Oxygen Etching of Silicon Surfaces
… oxygen etching behavior of the following silicon surface orientations: (001), (111), (113), (5 5 12) and (112). Most etching was performed at sample temperatures between 650 °C and 800 °C, at pressures of 3.3×10-7 and 1.5×10-7 Torr, and at an exposure of 200 L. Surface orientation strongly …
