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.

Physics Letters A, 2004 We propose a new approach to calculate recurrence plots of multivariate time series, based on joint recurrences in phase space. This new method allows to estimate dynamical invariants of the whole system, like the joint Renyi entropy of second order.

Conceptual recurrence plots: Revealing patterns in human discourse
IEEE Transactions on Visualization and Computer Graphics, 2012 Human discourse contains a rich mixture of conceptual information. Visualization of the global and local patterns within this data stream is a complex and challenging problem.

Time-Series Analysis Using Third-Order Recurrence Plots [PDF]
, 2023 Higher-order recurrence plots may enable us to reveal more structure than what is possible with traditional recurrence plots (RPs). While RPs attempt to detect recurrence relations by pair-wise comparison of time-delayed embeddings, given a time series ...

Quantification analysis of fuzzy recurrence plots
, 2022 The method of fuzzy recurrence plots has been introduced as an extension of the method of recurrence plots to display recurrences of the reconstructed phase-space trajectories of dynamical systems as grayscale images.

Characterization of ground motions using recurrence plots
Geofísica Internacional, 2013 Los modelos matemáticos tradicionales relacionados con el análisis de los terremotos son lineales y en algunos casos son incapaces de predecir determinados comportamientos, porque los datos que modelan pueden ser altamente no lineales y complejos.

The Vegetation–Climate System Complexity through Recurrence Analysis
Entropy, 2021 Multiple studies revealed that pasture grasslands are a time-varying complex ecological system. Climate variables regulate vegetation growing, being precipitation and temperature the most critical driver factors.

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 ...

Multiple Sensors Data Integration for Traffic Incident Detection Using the Quadrant Scan
Sensors, 2022 Non-recurrent congestion disrupts normal traffic operations and lowers travel time (TT) reliability, which leads to many negative consequences such as difficulties in trip planning, missed appointments, loss in productivity, and driver frustration ...
