排列熵及其在火灾试验数据中的应用

The permutation entropy and its applications on fire tests data

Flavia-Corina Mitroi-Symeonidis, Ion Anghel, Octavian Lalu, Constantin Popa

摘要:

基于室内火灾全尺寸实验数据,分析了室内火灾温度的有序/无序特性。在已知的排列/编码类型的熵用于分析时间序列,我们寻找那些更适合在火灾现象。文献的主要部分并不关注在全尺寸火灾实验中收集的数据的时间序列,因此我们不仅进行分析并报告结果,而且还讨论方法,算法,熵方法的新颖性和幕后细节。并讨论了复杂度计算中嵌入维数的选择问题。最后,提出了进一步的研究方向。

英文摘要:

Based on the data gained from a full-scale experiment, the order/disorder characteristics of the compartment fire temperatures are analyzed. Among the known permutation/encoding type entropies used to analyze time series, we look for those that fit better in the fire phenomena. The literature in its major part does not focus on time series with data collected during full-scale fire experiments, therefore we do not only perform our analysis and report the results, but also discuss methods, algorithms, the novelty of our entropic approach and details behind the scene. The embedding dimension selection in the complexity evaluation is also discussed. Finally, more research directions are proposed.
