Numerical Simulation of Shock and Detonation Waves Propagation in Various Media

Simulation is the imitation of the operation of a real-world process or system. The act of simulating something first requires that a model be developed; this model represents the key characteristics, behaviors and functions of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time.

Various, or Various Production, is an English dubstep/electronic music duo formed in 2002. The group blends samples, acoustic and electronic instrumentation, and singing from a revolving cast of vocalists. Its members, Adam and Ian, purposefully give very little information about the group or themselves, and tend to do little in the way of self-promotion. Nevertheless, the group began winning critical acclaim with its single releases in 2005 and 2006, with singers Rachel Thomas Davies and Nicola Kearey. Their full-length for XL, The World is Gone, arrived in July 2006. They have released a large number of vinyl EPs and 7" records, as well as digital exclusives for Rough Trade, iTunes, and Boomkat. They have released remixes of a large variety of artists (sometimes uncredited) such as Thom Yorke, Adele, Virus Syndicate, Dave Cloud, Cat Power, Emma Pollock and Ian Brown and participated with one track on the Vexille Movie Soundtrack.
