The regional research is conducted on the mechanical properties and performance of loess in slop northern Shaanxi Province, China. On precondition conforming to related technical regulations, equipment was purchased or selfdesigned machined conduct large-scale in-situ direct shear test participatory a high slope Through multiple field tests red soils four-level platform side engineering tunnel,...

The flow fields of direct numerical simulation turbulent channel are decomposed into large scales and small based on the interscale energy transfer spectra. former is characterized by streaks quasi-streamwise vortices even in outer layer, latter hairpin-like vortical structures that similar to original fields. We further investigated coherent associated with real-space transfer. formation small...

We provide a brief overview of the Discrete Element Method (DEM) for modeling large frictional contact problems in granular flow dynamics and quasi-static geomechanics applications. In terms of contact, DEM can be divided into two approaches: the Constraint Method (CM) or rigid-body approach, and the Penalty Method (PM) or soft-body approach. We give a detailed presentation of a DEM-PM contact ...

Abstract There is a need for small‐scale (gram) tests that accurately predicts large‐scale (kilogram) detonation performance of energetic materials. Many attempts have been made to create such tests, but they are either too narrow in scope [1–3] or fail demonstrate correlation with behavior [4–9]. When creating regulations relative safety and transportation, accurate crucial organizations as th...

The most research on the power consumption of 6T SRAM has been focused on the static power dissipation and the power dissipated by the leakage current. On the other hand, as the current VLSI technology scaled down, the sub-threshold current increases which further increases the power consumption. In this paper we have proposed 6T (8 X 8) SRAM cells using MCML technology which will reduce the le...

We study the Hausdorff Voronoi diagram of a set S of polygonal objects in the plane, a generalization of Voronoi diagrams based on the maximum distance of a point from a polygon, and show that it is equivalent to the Voronoi diagram of S under the Hausdorff distance function. We investigate the structural and combinatorial properties of the Hausdorff Voronoi diagram and give a divide and conque...

For the purpose of clarifying mechanism of local structure formations in magnetohydrodynamic (MHD) turbulence, energy transfers among various scales and positions of magnetic/kinetic energies in the course of roll-up processes of vortices are studied by direct numerical simulations (DNS) and orthonormalwavelet analysis. Initial shear layers are perturbed by three-dimensional random perturbation...

The morphology of the joint interface is described using geostatistical parameters such as the sill, range and slope of the initiaI part of the variogram. The methodology is also used to identify the scale effect and to determine the appropriate cutoff length of the sample which is representative for a direct shear test. The anisotropy characteristics of the interface are described using the si...
