Abstract: Pattern recognition was used on images of contacting three-dimensional sand particle assemblies to detect foreground sand grains that exhibit full-particle projections. Once identified, the roundness and sphericity of those ...

Abstract: AbstractA simple new test for determining the particle size distribution (PSD) for the full ASTM sand size range (0.075–4.75 mm) is introduced. It utilizes the recording of water pressures during sedimentation of ...
