Coal mine fire and human escape simulation

Coal mine fire and human escape simulation system is developed based on 3D Max and EON software for the purpose of coal mine safety training.The models,such as miners,roadways,typical equipments,fire and smoke are all constructed in 3D Max.The roadway models derived from real data,functions of each part are determined for the roadway based on the data,and then corresponding tunnel typical equipments are added.Emergency refuge system model is not only an important system model,but also an important destination for fire simulation and human escape.The roaming of the miners through the roadways,the interactive functions between users and computer,the fire process of beginning,spreading,and destroying,the human escape interaction are simulated in EON virtual reality software after these models have been input into it.Besides,collision detection based on hierarchical bounding volumes is also utilized.Simulation results suggest that this strategy can produce realistic virtual state and fire effect.While as part of the coal mine safety simulation and training System(CMSSTS),this work is far from what we expected,and there is more intensive work that should be done.

遣返成为引渡外的追逃方式研究

遣返在制度设计上不是追逃措施,但利用遣返程序追逃具有便捷、高效的特性。引渡虽是制度性的追逃措施,但引渡程序追逃具有冗长、复杂等特性。实践中,遣返被作为引渡之外的追逃方式,利用遣返程序追逃不破坏引渡条约。为弥补利用遣返程序追逃的缺陷并完善该追逃程序,应对被遣返逃犯以罪名特定原则适用法律以保障被遣返人的人权,并加强国家间法律文书的互认以进一步精简遣返追逃程序。
