Modeling patterns of breakdown (or archetypes) of human and organizational processes in accidents using system dynamics
System dynamics Systems thinking Human factors Organizational processes Accident analysis Complexity
2012/4/12
Systems approaches to safety have received growing attention in modern accident investigation techniques (e.g., STAMP, Accimap) with the emphasis shifted to the organizational dynamics (or archetypes)...
Research on sound fields generated by laser-induced liquid breakdown
photoacoustic effect optical breakdown radiated sound pressure plasma column
2011/5/9
The sound field excited by laser-induced liquid breakdown is studied through theory and
experiment by using fundamental theories of acoustics. It is shown that there is a logarithmic
linear relation...

交通流Breakdown现象与交通扰动演化模型
交通流breakdown 交通扰动 breakdown概率 跟车行为 交通波动理论
2010/9/26
建立了用以间接证明交通流自发breakdown现象的交通扰动演化模型。基于跟车思想制定了“继承”和“改变”两种车辆行驶规则；基于交通波动理论刻画了车辆经历扰动的减速波和加速波，并结合到达车流的车头时距分布，建立了扰动演化模型。模型考虑了“迟滞”现象和“二次扰动”现象，采用蒙特卡罗方法进行数值模拟，对比了五种形式的breakdown概率，分析了模型中重要参数对计算结果的影响及原因
