论文摘要
储层计算是预测湍流的有力工具，其简单的架构具有处理大型系统的计算效率。然而，其实现通常需要完整的状态向量测量和系统非线性知识。我们使用非线性投影函数将系统测量扩展到高维空间，然后将其输入到储层中以获得预测。我们展示了这种储层计算网络在时空混沌系统上的应用，该系统模拟了湍流的若干特征。我们表明，使用径向基函数作为非线性投影器，即使只有部分观测并且不知道控制方程，也能稳健地捕捉复杂的系统非线性。最后，我们表明，当测量稀疏、不完整且带有噪声，甚至控制方程变得不准确时，我们的网络仍然可以产生相当准确的预测，从而为实际湍流系统的无模型预测铺平了道路。
Metro systems are part of major transportation systems for big cities. Evacuation is a key challenge for metro systems in case of fire or terrorist attacks. In case of evacuation, wheelchair-assisted evacuees might take a longer time. In order to understand the effect of assisted and non-assisted evacuees on evacuation, a simulation is conducted in this study. Platform evacuation and train evacuation simulation are done. A train load survey is conducted to understand the number of evacuees inside a train. Two different layouts of stations are considered, underground island-type platforms and elevated platforms. Simulation of wheelchair-assisted and non-assisted evacuees is done. Design of experiment is used to create full factorial and fractional factorial designs to take input of different factors in simulation. The main factors affecting the total evacuation time are calculated using the design of experiment. It is found that wheelchair-assisted evacuees take longer time than non-assisted evacuees in both underground and elevated station platforms. It is also found that efforts are needed to increase the speed of the non-assisted evacuees also.
