Nonlinear dynamical analysis of GNSS data: quantification, precursors and synchronisation

open access: yesProgress in Earth and Planetary Science, 2018
The goal of any nonlinear dynamical analysis of a data series is to extract features of the dynamics of the underlying physical and chemical processes that produce that spatial pattern or time series; a by-product is to characterise the signal in terms ...

Effect of the Long-Term Mean and the Temporal Stability of Water-Energy Dynamics on China’s Terrestrial Species Richness

open access: yesISPRS International Journal of Geo-Information, 2017
Water-energy dynamics broadly regulate species richness gradients but are being altered by climate change and anthropogenic activities; however, the current methods used to quantify this phenomenon overlook the non-linear dynamics of climatic time-series

Gear Fault Recognition based on Local Detail Spectrum

open access: yesJixie chuandong, 2018
Unlike the normal recurrence quantification analysis( RQA) which pay attention to the distribution of different kinds of lines such as diagonal lines,vertical lines and horizontal lines,a new perspective to study recurrence plot( RP) is developed and the

Energy-efficient recurrence quantification analysis

open access: yes
Recurrence quantification analysis (RQA) is a widely used tool for studying complex dynamical systems, but its standard implementation requires computationally expensive calculations of recurrence plots (RPs) and line length histograms. This study introduces strategies to compute RQA measures directly from time series or phase space vectors, avoiding ...
