Discrete element modeling of explosion-induced fracture extension in jointed rock masses

The explosion process of explosives in a borehole applies a very high pressure on its surrounding rock media. This process can initiate and propagate rock fractures, and finally, may result in the rock fragmentation. Rock fragmentation is mainly caused by the propagation of inherent pre-existing fractures of the rock mass and also from the extension of the newly formed cracks within the intact ...

Kursk Explosion

On 12 August 2000 two explosions damaged the Russian submarine, the Kursk. The largest event was well recorded at seismic networks in northern Europe, which we then modeled. We developed a hybrid method based on generalized ray theory that treats an explosive source embedded in a fluid and recorded along continental paths. Matching record sections of observations with synthetics, we obtain an e...

Population explosion.

Correspondence It would appear that four bodies are concerned , the driver, the public, the insurance companies, and the doctors. The first three might be taken together, for I understand that the insurance companies are no more concerned with the elderly driver as an insurance risk than with anyone else; in fact if the amount of premium required is a criterion he is considered to be less of a ...

Optimal Flood Mitigation over Flood Propagation Approximations

Globally, flooding is the most frequent among all natural disasters, commonly resulting in damage to infrastructure, economic catastrophe, and loss of life. Since the flow of water is influenced by the shape and height of topography, an effective mechanism for preventing and directing floods is to use structures that increase height, e.g., levees and sandbags. In this paper, we introduce the Op...
