Stickiness and recurrence plots: An entropy-based approach
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2023 The stickiness effect is a fundamental feature of quasi-integrable Hamiltonian systems. We propose the use of an entropy-based measure of the recurrence plots (RPs), namely, the entropy of the distribution of the recurrence times (estimated from the RP), to characterize the dynamics of a typical quasi-integrable Hamiltonian system with coexisting ...

Deep Transfer Learning for Vulnerable Road Users Detection using Smartphone Sensors Data
Remote Sensing, 2020 As the Autonomous Vehicle (AV) industry is rapidly advancing, the classification of non-motorized (vulnerable) road users (VRUs) becomes essential to ensure their safety and to smooth operation of road applications.

Reducing sojourn points from recurrence plots to improve transition detection: Application to fetal heart rate transitions [PDF]
, 2015 International audienceThe analysis of biomedical signals demonstrating complexity through recurrence plots is challenging. Quantification of recurrences is often biased by sojourn points that hide dynamic transitions.

Bearing fault diagnosis based on recurrence plots and local non-negative matrix factorizatio
Gong-kuang zidonghua, 2017 In view of non-stationary characteristics of bearing vibration signal and difficulty of extracting fault parameters in reality, a bearing fault diagnosis based on recurrence plots and local non-negative matrix factorization was proposed.

Nonlinear dynamics of giant resonances in atomic nuclei [PDF]
, 1998 The dynamics of monopole giant resonances in nuclei is analyzed in the time-dependent relativistic mean-field model. The phase spaces of isoscalar and isovector collective oscillations are reconstructed from the time-series of dynamical variables that ...

Recurrence plot statistics and the effect of embedding
, 2005 Recurrence plots provide a graphical representation of the recurrent patterns in a timeseries, the quantification of which is a relatively new field. Here we derive analytical expressions which relate the values of key statistics, notably determinism and

EPL (Europhysics Letters), 2016 Recurrence plots display binary texture of time series from dynamical systems with single dots and line structures. Using fuzzy recurrence plots, recurrences of the phase-space states can be visualized as grayscale texture, which is more informative for pattern analysis.
