Permutation entropy (PeEn) is a complexity measure that originated from dynamical systems theory. Specifically engineered to be robustly applicable to real-world data, the quantity has since been utilised for a multitude of time series analysis tasks. In ... see more

Analysis of survey data is a matter of significant concern as it plays a key role in organizational and behavioral research. Quantitative survey data possesses several distinct characteristics i.e., fixed small range of ordinal values, importance of respo... see more

Permutation entropy has become a standard tool for time series analysis that exploits the temporal and ordinal relationships within data. Motivated by a Kullback–Leibler divergence interpretation of permutation entropy as divergence from white noise, we e... see more

Customer Relationship Management (CRM) turns out to be a relevant source of competitive advantage in a highly competitive scenario, as in the video game’s industry. Thereby, the main objective of this study is to develop and validate a scale to assess pla... see more

A new parallel analysis method is proposed for determining the influence of tolerances on the dipole antenna parameters. The method is based on antennas characteristics: small tolerances, interindependence and monotone dependence of radiation pattern on o... see more

Background: Osteoporosis is a systemic skeletal disease characterized by low bone mineral density (BMD) and micro-architectural deterioration of bone tissue, leading to bone fragility and increased fracture risk. Since Panoramic image is a feasible and re... see more

Bloodstain pattern analysis has become a field of specialization in Forensic sciences and plays an important role in the reconstruction of events at a crime scene. Research, books, and articles have been published on the analysis and interpretation of blo... see more

This paper is devoted to change-point detection using only the ordinal structure of a time series. A statistic based on the conditional entropy of ordinal patterns characterizing the local up and down in a time series is introduced and investigated. The s... see more

Cloud computing services bring new capabilities for hosting and offering complex collaborative business operations. However, these advances might bring undesirable side-effects, e.g., introducing new vulnerabilities and threats caused by collaboration and... see more
