Institute for Information Transmission Problems. Russian Academy of Sciences. Senior Researcher, Leading Researcher, Principal Researcher, Deputy Head of the Sector of Mathematical Methods in the Control Theory. Description of work: Investigation of stability of asynchronous systems. New notions of stability in classes of desynchronization were introduced and methods of investigation stability of asynchronous systems were developed. Investigation of influence of controllability-type properties on transients in asynchronous systems. Applications of the stability theory of asynchronous systems for analysis of dynamics of datagram networks. Investigation of influence of temporal/spatial discretization on dynamics of continuous systems. Investigation of stability of asynchronous neural networks. Investigation of the problem of generalized spectral radius of a family of linear operators.

Research Institute of Remote Control Systems. "NPO ASU Moskva". Senior Researcher. Description of work: Investigation of stability of phase and frequency desynchronized systems. Development of symbolic dynamics technique for studying of stability of frequency desynchronized systems. Modeling of the air pollution in the Moscow region.



National Cardiology Research Center. Russian Academy of Medical Sciences, Moscow. Senior Engineer, Junior Researcher, Senior Researcher, Leading Researcher, Head of Group of computer real-time diagnostic of heart rhythm in coronary care units, Head of Group of image processing. Description of work: Electrocardiogram parameters estimating. Designing of automated computer system for real-time diagnostic in coronary care units. Developing of new algorithms for fast smoothing of electrocardiograms and fast elimination of artifacts, based on "median filtering principle". Designing of median-filtering-based reliable algorithms for determining electrocardiogram wave parameters (QRS-complexes and P-wave) and edge detection in radioisotope images. Topological classification of singularities. New necessary and sufficient conditions for topological classification of singularities for sub-definite mappings. Application of the developed methods to investigation of Hopf bifurcation problem.



Institute for Control Problems. Academy of Sciences of the USSR, Moscow. Postgraduate student. Description of work: Investigation of bifurcation effects accompanying the loss of equilibrium of autonomous/periodic differential/difference equations. It was found that in general situation the loss of stability is accompanied by bifurcation of long periodic solutions with periods growing to infinity at the moment of branching. This phenomenon was named phenomenon of subfurcation. Later the simple explanation of subfurcation phenomenon was given by V.Arnold (but only for sufficiently smooth case).



Institute of Mathematics of the Voronezh State University, Voronezh. Engineer. Description of work: Analysis of vibrostability conditions for 2nd order differential equations.
