This paper presents a cellular automaton model without step back for pedestrian dynamics considering the human behaviors which can make judgments in some complex situations. simulate movement with different walk velocities through update at time-step intervals. Two kinds of boundary conditions including periodic and open counter flow are considered, their dynamical characteristics discussed. Simulation results show that condition there three phases patterns, i.e., freely moving phase, lane...
This paper investigates the challenges faced in designing an integrated information platform for emergency response management and uses Beijing Olympic Games as a case study. The research methods are grounded action research, participatory design, situation-awareness oriented design. completion of more than two-year industrial secondment six-month field studies ensured that full understanding user requirements had been obtained. A service-centered architecture was proposed to satisfy these...
Skin burn induced by thermal radiation or heat source is one of the common but severe, injuries in firefighting and some industry work exposed to intensive radiation. In this article, a multi-layer skin model on mass transfer presented article investigate effects blood perfusion, water diffusion, vaporization tissue temperature after removing source. The numerical results are good agreement with previous experimental results. A parametric study carried out geometrical parameters, initial...
The thermal performance of firefighters' protective clothing entrapping multiple air gaps and exposed to low heat fluxes has been studied using a newly designed bench-scale test apparatus. Different gap sizes (0, 2 5 mm), entrapped positions within the fabric system between outer shell, moisture barrier, liner, respectively, were investigated at three levels radiation (2, 10 kW/m ) over prolonged period. effect size its position on transfer in multilayer are interpreted terms theoretical...
The study of crowd behavior is essential for the safe organization mass events. However, precise quantitative empirical data are insufficient due to lack event scenarios suitable observation. In this paper, during a in which many people go through door and then pass bridge studied by new method based on flow field visualization algorithm widely used fluid experiments. Two important movement phases, laminar stop-and-go waves bottleneck area, investigated. results show that velocity profile...
