The problem of evaluating the state of systems that are open with respect to input and output for the purpose of creating a system for evaluating states when testing complex objects is considered. Solving the problem will make it possible to eliminate ambiguity in cases of insufficiency of the output parameters and where uncontrolled parameters exert an… (More)
On the basis of the study of electrocardiograms by nonlinear dynamics methods, we consider the possibility to reveal pathologies of patients with different heart failures. Two parameters were analyzed: the correlation dimension and embedding dimension of RR-intervals of electrocardiorgams. Some restrictions of this method and the ways of their solutions are… (More)
A new method of increasing to accuracy of the measurement microwave parameters devices of communication by six-port reflectometer are considered.
Great success and profit of the chaos suppression phenomenon in applications led to the widespread opinion that chaotic oscillations may always be stabilized by parametric perturbations. Nevertheless, in what cases the chaos can be suppressed by such a manner? In general, this question means that we should perturb the system strictly within the chaoticity… (More)
A method of measurement parameters of microwave devices of communication by six-port reflectometer is considered, the problem of the determination relations waves of the voltages when the signals from two generators passed through double six-port-reflectometer simultaneous influence on inputs of the measured two-port generator signals is solved.
A general model of the nonlinear interaction of two impulse systems was developed, which describes some types of cardiac arrhythmias. Phase locking phenomena were studied with consideration for refractoriness time. The phenomena of tongue splitting and the overlapping of the major synchronization regions were revealed. The results obtained make it possible… (More)
On the basis of the FitzHugh-Nagumo-type model we investigate the possibility of suppression of the spiral wave turbulence by weak pacemaker excitations. We consider different ways of media stabilization and study the dependence of the suppression efficiency on the excitation zone shape and media parameters. Also, we analyze the frequency of target waves in… (More)
Large-scale dynamical properties of complete chromosome DNA sequences of eukaryotes are considered. Using the proposed deterministic models with intermittency and symbolic dynamics we describe a wide spectrum of large-scale patterns inherent in these sequences, such as segmental duplications, tandem repeats, and other complex sequence structures. It is… (More)
