Abstract

We describe an efficient method for stimulating the distributed response of complex asymmetrically branching networks which satisfy requirements of network self-consistency. Individual tree links may be dispersive and lossy. As a case in point we simulate the response of the human lung, and characterize the variations in pressure with frequency, path, and position. The effects of tree asymmetry are found to be significant above 100 Hz in the air-filled lung.

摘要

我们描述了一种有效的方法，用于刺激满足网络自洽性要求的复杂不对称分支网络的分布式响应。单个树状链路可能是色散的且有损耗的。作为一个例子，我们模拟了人类肺部的响应，并表征了压力随频率、路径和位置的变化。发现在充气肺中，树状不对称的影响在100Hz以上是显著的。
