Complex Dynamics of Piecewise Linear Model of the Van der Pol Oscillator Under External Periodic Force

The electronic model of Van der Pol oscillator with piecewise linear V-I--characteristics of nonlinear element is proposed. It is carried out the experimental investigations of behaviour of the Van der Pol oscillator under external periodic force. The parameter plane "the amplitude of external force -- the frequency of external force" for the dynamical regimes of the oscillator is experimentally plotted. It is shown in experiments and numerical simulations that transition to chaos in the oscillator takes place through the period doubling cascade. It is revealed that the internal structure of the synchronization tongues has the characteristic view as for the crossroad area.

Using of Phenomenological Piecewise Continuous Map for Modeling of Neurons Behaviour

A piecewise continuous map for modeling bursting and spiking behaviour of isolated neuron is proposed. The map was created from phenomenological viewpoint. The map demonstrates oscillations, which are qualitatively similar to oscillations generating by Rose-Hindmarsh model. The synchronization in small ensembles of the maps is investigated. It is considered the different number of elements in the ensemble and different connectivity topologies.

Generating high-dimensional chaotic signals by the sum

The method of generating of high-dimensional oscillations on the basis of summing of low-dimensional chaotic signals of noncoupled dynamical systems is investigated. It is shown that the correlation dimension of attractor reconstructed from such oscillations is equal to the sum of dimensions of the original signals. The possibilities for obtaining of homogeneous high-dimensional chaotic attractor are numerically demonstrated with the original signals of R{ö}ssler system.

The creation of high-dimensional oscillations from low-dimensional systems

The complication of chaotic oscillation under its transformation by linear inertial process is discussed. It is shown that such complication is begun from large scales of attractor and is pure dynamical process.

On reconstruction of chaotic attractor from time series represented as "clusters"

The method of reconstruction of an attractor from a set of short time series ({\it clusters}) is proposed and discussed. This method is most useful for correlation dimension estimation of experimental data.
