Distinguishing quasiperiodic dynamics from chaos in short-time series.

We propose a procedure to distinguish quasiperiodic from chaotic orbits in short-time series, which is based on the recurrence properties in phase space. The histogram of the return times in a recurrence plot is introduced to disclose the recurrence property consisting of only three peaks imposed by Slater's theorem. Noise effects on the statistics are studied. Our approach is demonstrated to b...

real‑time detection of precursors to epileptic seizures: non‑linear analysis of system dynamics

we propose a novel approach for detecting precursors to epileptic seizures in intracranial electroencephalograms (ieeg), which is based on the analysis of system dynamics. in the proposed scheme, the largest lyapunov exponent of the discrete wavelet packet transform (dwpt) of the segmented eeg signals is considered as the discriminating features. such features are processed by a support vector ...

The colour of noise in short ecological time series data.

The statistical properties of ecological time series data and general trends therein have historically been of great interest to ecologists. In recent years, there has been a focus on establishing the relative importance of 'memory' in these data. The classic study by Pimm & Redfearn (1988 Nature, 334, 613-614) has been extremely important in establishing within the ecological community the ide...

Chaos Analysis for Ekg Time Series Data

Our project aims at testing various measures of chaos in time series data from an electrocardiogram (EKG). We examine data from three types of patients who we assume to produce varying EKG dynamics. We use time-delay embedding and calculate correlation dimensions to determine if the data is chaotic or random. Our results indicate that there is some evidence of deterministic chaotic behavior in ...
