Abstract: The ordinal patterns of time series provide a variety of information about the dynamic characteristics of the underlying process. With the ordinal symbolic approach, recently, a permutation-based Hill's diversity index has been proposed as a… read more here.

DOI: 10.3390/e21111079
Abstract: Extracting effective features from ship-radiated noise is an important way to improve the detection and recognition performance of passive sonar. Complexity features of ship-radiated noise have attracted increasing amounts of attention. However, the traditional definition… read more here.
