Multi-Mode Wave Propagation in Anisotropic Media

Phaseshift operators are presented that enable planewave propagation through media that are transversely anisotropic. These operators propagate planewaves in all three spatial dimensions for all three components, and they are developed to reside   more››

Gas Hydrates: Evaluating Their Technical Producibility

It is estimated that the amount of natural gas trapped in hydrates around the world is roughly two orders of magnitude more than the recoverable gas in conventional reservoirs. Activities are underway in relation to a number of hydrate accumulations:   more››

Some Mathematical Aspects of Earthquake Research

An earthquake is the motion produced when stress within the Earth builds up over a long period of time until it exceeds the strength of the rock, which then fails by breaking along a fault. Although catastrophic earthquakes are rare, earthquakes occu   more››
