چکیده

The theoretic ground of a local-topological method for defining a minimal attractor embedding dimension on the basis of matrix decomposition is proposed. The investigation of digital electrocardio signals using local-topological analysis of chaotic attractor trajectories is carried out. The computer confirmation of the theoretical results is presented.

Model Based Method for Determining the Minimum Embedding Dimension from Solar Activity Chaotic Time Series

Predicting future behavior of chaotic time series system is a challenging area in the literature of nonlinear systems. The prediction's accuracy of chaotic time series is extremely dependent on the model and the learning algorithm. On the other hand the cyclic solar activity as one of the natural chaotic systems has significant effects on earth, climate, satellites and space missions. Several m...

Attractor Based Analysis of Centrally Cracked Plate Subjected to Chaotic Excitation

The presence of part-through cracks with limited length is one of the prevalent defects in the plate structures. Due to the slight effect of this type of damages on the frequency response of the plates, conventional vibration-based damage assessment could be a challenging task. In this study for the first time, a recently developed state-space method which is based on the chaotic excitation is ...

Analysing the Chaotic Motion of a Driven Pendulum

We analyse the chaotic motion of a periodically driven damped pendulum. Time series of the angular velocity are sampled and investigated numerically. Parameters of the driving force and the damping are reconstructed from the velocity by numerically adapting the equation of motion. The delay time required to embed the attractor in a space of delay coordinates is derived from an extension of the ...

Distinguishing and recognition of pathological speech based on estimation of control parameter of chaotic attractor

This paper investigates the approach for revealing pathological speech signal based on estimating specific geometric structure of Lorenz attractor in a chaotic regime. Analysis of the Lorenz attractor on the basis of proposed nonlinear decomposition into matrix series is developed. This analysis permits to estimate the values of characteristic parameters (including control one) of Lorenz attrac...
