Wavelet multifractal detrended fluctuation analysis of encryption and decryption matrices [PDF]

open access: yes, 2013
"In this paper, we study in detail the multifractal features of the main matrices of an encryption system based on a rule-90 cellular automaton. For this purpose we consider the scaling method known as the wavelet transform multifractal detrended ...

A New Look at Calendar Anomalies: Multifractality and Day-of-the-Week Effect

open access: yesEntropy, 2022
Stock markets can become inefficient due to calendar anomalies known as the day-of-the-week effect. Calendar anomalies are well known in the financial literature, but the phenomena remain to be explored in econophysics.

Categorization of Stringed Instruments with Multifractal Detrended Fluctuation Analysis

open access: yesCoRR, 2016
Categorization is crucial for content description in archiving of music signals. On many occasions, human brain fails to classify the instruments properly just by listening to their sounds which is evident from the human response data collected during our experiment.
