Model Estimation of Depression-focused Groundwater Recharge and its Variability in the Canadian Prairies
… (VSMB-DUS). Automated digital elevation model (DEM) analysis was used to identify topographical depressions across Alberta and Saskatchewan and to determine hydrologically relevant parameters. Hourly meteorological data of Alberta and Saskatchewan, along with land-use data collected from …

Measurement of particle interaction properties for the incorporation into Discrete Element Methods
… numerical tool, the Discrete Element Method (DEM), is a promising technique for predicting the dynamics of charge motion with in a mill. Particle interactions in DEM are calculated by contact force and force displacement laws at each particle contact. These contact events are characterized by …

Late Cenozoic uplift of southeastern Tibet
Recent field work and DEM analysis show that remnant, local areas of a low-relief land scape (or "erosion surface") are geographically continuous across the southeastern Tibetan Plateau margin and can be correlated in order to define the maximum envelope of topogra phy of the margin itself. This …

A distributed simulation environment for multibody physics
… procedure in the overall discrete element analysis pipeline. The computational cost of contact detection grows as a function of both the number of particles and the complexity of the geometric representation of each body. This thesis presents algorithms that significantly reduce the …

New data structure and process model for automated watershed delineation
DEM analysis to delineate the stream network and its associated subwatersheds are the primary steps in the raster-based parameterization of watersheds. There are two widely used methods for delineating subwatersheds. One of these is the Upstream Catchment Area (UCA) method. The UCA method employs a …

Retracing the 1910 Carruthers Royal Geographical Society Expedition to the Turgen Mountains of Mongolia – Reconstruction of a Century of Glacial Change
… lobes were surveyed by GPS. Finally, spatial analysis was conducted in the computer laboratory using a GIS to generate a „historic‟ elevation model from the 1910 map and compare it to a modern DEM generated from SRTM data. Map analysis software was employed to evaluate cartometric accuracy of …

MULTI-PHYSICS DESIGN AND ANALYSES OF LONG LIFE REACTORS FOR LUNAR OUTPOSTS
… Moon using a transient Discrete Element Method (DEM) analysis in lunar gravity. In addition, this research addresses the post-operation storage of the SCoRe and PeBR concepts, below the lunar surface, to determine the time required for the radioactivity in the used fuel to decrease to a low level …
