Development of an open source Debris Flow Simulator for “Sabo” (DFSS) [PDF]
E3S Web of Conferences, 2023 We report the development of an open source “Debris Flow Simulator for Sabo” (DFSS). DFSS consists of three models corresponding to three geomorphological regions (mountain hillside slopes, mountain-to-plain river channels, and lower plains).

Debris development in fretting contacts – Debris particles and debris beds [PDF]
Tribology International, 2020 In this study, the formation and destruction of compacted beds of oxidized debris particles are investigated. Fretting tests of steel specimens were conducted, employing a cylinder-on-flat geometry with displacement amplitude being varied. The debris was examined, both in the form of the debris beds and in the form of loose debris; together, these were

Orbital debris–debris collision avoidance [PDF]
Advances in Space Research, 2011 We focus on preventing collisions between debris and debris, for which there is no current, effective mitigation strategy. We investigate the feasibility of using a medium-powered (5 kW) ground-based laser combined with a ground-based telescope to prevent collisions between debris objects in low-Earth orbit (LEO).

Risk assessment in the North Caucasus ski resorts [PDF]
Natural Hazards and Earth System Sciences, 2016 Avalanches pose a significant problem in most mountain regions of Russia. The constant growth of economic activity, and therefore the increased avalanche hazard, in the North Caucasus region lead to demand for the development of large-scale avalanche ...
