Terrorism Knowledge Base
The MIPT Terrorism Knowledge Base (TKB) was an online portal containing information on terrorist incidents, leaders, groups, and related court cases. It was active from September 2004 to March 2008 and is now defunct, but the group profiles that were included in the knowledge base are now hosted by the National Consortium for the Study of Terrorism and Responses to Terrorism. The TKB was sponsored by the National Memorial Institute for the Prevention of Terrorism (MIPT), a non-profit organization funded by the United States Department of Homeland Security. A significant participant was Cyc, which encoded the knowledge base in mathematical logic, and allowed complex logical queries over the knowledge base. The TKB contained historical information on terrorism dating back to 1968, with over 29,000 incident profiles, 900 group profiles, and 1,200 leader biographies. The TKB contained several features to analyze terrorism data, including graphing tools, interactive maps, and statistical ...

Explosion Following The Plane Impact Into The South Tower (WTC 2) - B6019~11
An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be generated by a slower expansion that would normally not be forceful, but is not allowed to expand, so that when whatever is containing the expansion is broken by the pressure that builds as the matter inside tries to expand, the matter expands forcefully. An example of this is a Volcano, volcanic eruption created by the expansion of magma in a magma chamber as it rises to the surface. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. wikt:subsonic, Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes For an explosion to occur, there must be a rapid, forceful expansion of matter. There are numerous ways this can happen, both natura ...
