简介:以便评估水分发系统的地震可靠性并且相应地做康复决定,估计管道损坏状态并且基于管子漏模型进行功能的分析是必要的。当地震发生了时,水分发系统不停地与漏服务。由与漏在管道的中心增加一个虚拟节点,压力驱动的分析的一条有效途径为模仿许多低相对情形被开发,并且一个水力的漏模型也被造与地震损坏执行水供应网络的水力的分析。然后,mean-first-order-second-moment方法被用来分析水分发系统的地震有用性。根据评价分析,被破坏或突现地在重漏被孤立并且修理的管子,它改进了水供应网络的能力并且将为提高系统的地震可靠性组成基础。水分发系统上的地震可靠性和康复决定分析的建议途径被表明通过案例研究有效。

简介:圆形的电的阻抗断层摄影术(EIT)的一个直觉的2D模型有小尺寸电极的传感器基于分析功能的理论被建立。模型的Thevalidation从Laplace方程的答案用结果被证明。建议在上到到敏感的有病条件的性质的电极优化和解释,矩阵基于模型被提供,它考虑电极距离并且能通过保角的转变与任何简单连接区域被概括到传感器。图象重建算法基于模型被实现用从在TianjinUniversity开发的EIT系统收集的试验性的数据显示出模型的可行性。在有一种人的像胸的配置的模拟,电的传导性分布基于模型的保角的转变用等位的背设计(EBP)和Tikhonovregularization(TR)被重建。算法对联机图象重建基于模型合适,重建的结果在尺寸和位置两个都好。
简介:蛋白质符合构造上的水的影响被在不同的水系统模仿模型蛋白质溶解酵素的分子的动力学调查。有有六戒指的水的水模型和溶解酵素水簇系统建模的TIP3P的溶解酵素水系统被评估。另外,在溶解酵素附近的溶剂的光线的分发功能是计算的。在溶解酵素附近的水分子的分发类似于水簇的,这被发现。二面的角度的分析和溶解酵素的二硫化物契约证明溶解酵素的符合构造严重地在溶解酵素水系统与那相比在溶解酵素水簇系统被损坏。这差别能被归因于在溶解酵素和水簇之间的分子间的氢契约的更大的数字的形成。是与分析一致水簇能在溶解酵素的热变性作用的过程改变变性作用的度。
