Generally, the evaluation and assessment of the critical condition of rill formation are useful for a better understanding of soil erosion processes. The inherence characteristics of soils, which have much dynamic variations on the hillslopes and are affected by rill formation, are the soil critical shear stress and soil erodibility factors. This study aims to assess experimental rill incision ...

Abstract Recent advances in remote sensing techniques and computer algorithms allow accurate, abundant, high-resolution geometric information retrieval for rock mass characterization from 3D point clouds. The automatic application of the extracted local scale rockfall susceptibility assessment, where discontinuities characteristics play a major role rocky slope stability, requires step by logic...

The importance of the support function in representation, manipulation, and analysis of convex bodies can indeed be compared with that of the Fourier transform in signal processing. The support function, in intuitive terms, is the signed distance of a supporting plane of a convex body from the origin point. In this paper we show that, just as simple multiplication in the Fourier transform domai...

For the stability analysis of rock slope, it is very critical to obtain spatial geometric characteristics structural surfaces mass accurately and effectively. As for a high-steep slope an iron ore mine, in order solve problems inefficiency high risk traditional manual geological survey, survey evaluation was carried out by adopting unmanned aerial vehicle digital photogrammetry (UAV-DP) technol...

OBJECTIVE Longitudinal quantitative evaluation of cartilage disease requires reproducible measurements over time. We report 8 years of quality assurance (QA) metrics for quantitative magnetic resonance (MR) knee analyses from the Osteoarthritis Initiative (OAI) and show the impact of MR system, phantom, and acquisition protocol changes. METHOD Key 3T MR QA metrics, including signal-to-noise, ...

In June 2008, the Shenzhen landfill slope failed. This case is used as an example to study the deformation characteristics and failure mode of a slope induced by high water levels. An integrated monitoring system, including water level gauges, electronic total stations, and inclinometers, was used to monitor the slope failure process. The field measurements suggest that the landfill landslide w...
