Tarim Basin distributed widely two stages of Permian volcanic rocks. However, the location and timing of these rocks pinching out and the relationship between Ordovician carbonate hydrothermal reservoirs and fault activity remain unclear. The Shunnan (Shunnan here in after referred to as SN) 1 3-D well zone in the eastern Tarim Basin contains volcanic rocks, and the Ordovician layer contains a hydrothermal...

In recent years, with the popularity of crime prevention system, which plays a positive role in the field of crime prevention. But a number of security facilities are wasted due to no risk optimization of crime prevention system. This paper firstly establishes a risk optimization model on crime prevention system. Secondly, combinatorial optimization technology is used to calculate this model. Finally,...
