Geomatics, Natural Hazards & Risk, 2020 Considering the critical importance of the quality of input data for landslide susceptibility, we investigate the performance improvements that can be achieved by different globally available digital elevation models (DEMs) using different state-of-the ...

Earth and Space Science, Volume 11, Issue 12, December 2024.Abstract Satellite‐derived global digital elevation models (DEMs) are essential for providing the topographic information needed in a wide range of hydrological applications. However, their use is limited by spatial resolution and vertical bias due to sensor limitations in observing bare terrain.

Monitoring bulk material pressure on bottom of storage using DEM
Open Engineering, 2019 This article focuses on the experimental verification of a mathematical derivation of Janssen’s theory, which describes the distribution of pressures within the bulk material and pressure distribution on the walls of storage facilities.

River, Volume 3, Issue 4, Page 426-437, November 2024.Abstract The present study aimed to delineate a robust watershed boundary and extract its morphometric parameters in the Karnaphuli watershed, Bangladesh, using different digital elevation models (DEMs). Two DEMs, the shuttle radar topographic mission (SRTM) and the terra advanced spaceborne thermal emission and reflection radiometer (ASTER), were ...

3‐D impulse‐based level‐set method for granular flow modeling
International Journal for Numerical Methods in Engineering, Volume 125, Issue 17, 15 September 2024.Abstract We explore the viability of modeling dynamic problems with a new formulation of an impulse‐based Level‐Set DEM (LS‐DEM). The new formulation is stable, fast, and energy conservative. However, it can be numerically stiff when the assembly has substantial mass differences between particles.

International Journal for Numerical Methods in Engineering, Volume 125, Issue 5, 15 March 2024.Abstract The level‐set‐discrete‐element‐method (LS‐DEM) was developed to overcome the shape limitation of traditional discrete element method. LS‐DEM's shape generality relies on a node‐based surface discretization of grain boundary, and it has been used to shed new light of a variety of granular mechanics applications with realistically shaped grains ...

Wortassoziationen: Ein interkultureller Vergleich zwischen dem Deutschen, dem Arabischen und dem Französischen [PDF]
Zeitschrift für Interkulturellen Fremdsprachenunterricht, 2015 Die kontrastive Semantik stellt nach wie vor erhebliche Unterschiede zwischen semantischen Merkmalen der Begriffe in verschiedenen Sprachen fest. Diese Unterschiede werden durch die lexikalische Oberfläche der Sprache nicht zum Vorschein gebracht. Mittels eines Wortassoziationsexperiments werden in dieser Untersuchung die konzeptuellen Unterschiede ...
