As the main means of monitoring and early warning of geological disaster, the slope stability analysis is an important part of the geological disaster prevention project. GIS plays an important role in the evaluation of slope stability due to its powerful functions for data processing and spatial analysis. This article discusses the key technology of GIS applied in the slope bolt support design...

Snow drifting is a typical natural disaster, and an increasing importance has been attached to its theory research and field observation for the sake of cold region engineering. Numerical simulation, as an efficient method of studying snow drifting, promises to be widely applied in this field. In this paper, the finite element method is used to simulate the wind velocity field. Selected upwind,...

A new algorithm is proposed for computing the embedding dimension and delay time in phase space reconstruction. It makes use of the zero of the nonbias multiple autocorrelation function of the chaotic time series to determine the time delay, which efficiently depresses the computing error caused by tracing arbitrarily the slop variation of average displacement (AD) in AD algorithm. Thereafter, ...

Ledakan menghasilkan kebakaran,begitu juga sebaliknya ledakan. Perbedaan antara berada rate of energy realease ...

Solid assembly meshing has all of the same “dirty geometry” induced issues as single part meshing but also has the difficulty associated with generating a conformal mesh between solids where solid-solid interfaces are not obvious. Mesh generators usually don’t have CAD assembly constraint information to identify interfacing solids and must therefore rely on geometric proximity to deduce these i...

The AVHRR compatible vegetation index derived from MERIS full resolution (FR) data is based on top of atmosphere radiances (ESA L2 data). This continuity index is developed using radiative transfer models for simulating the reflectance of the broad spectral channels of the NOAA – AVHRR and the small spectral bands of MERIS. A linear combination of MERIS channels describes each AVHRR channel. Th...
