Victor F. Dailyudenko

Background

Victor F. Dailyudenko was born on August 24, 1959. He was Belarusian and was associated professionally with Minsk and the research institutions of the National Academy of Sciences of Belarus. His parents were Nina and Feodor.

Education

Dailyudenko studied at Belarussian State University, where he completed a degree in radiophysics and electronics in 1981. He subsequently pursued graduate research in mathematics and computational physics at the same university, completing a Doctor of Philosophy degree in 1987. His later scholarly designation was candidate of physical and mathematical sciences.

Career

Dailyudenko began his research career in 1981 at the Institute of Informatics Problems, working on computer analysis of nonlinear time series and data storage. His research addressed chaotic dynamics, attractor reconstruction, fractal analysis, delayed-feedback systems, and the processing of experimental and biomedical signals. From 2002 to 2011 he served as a senior researcher working on complex systems with nonlinear feedback and active media. His work combined analytical and numerical methods, including Lyapunov-exponent calculations, local and integrated instability estimates, topological analysis of phase trajectories, and computational methods for extracting dynamical characteristics from time series. Applications included electrocardiographic signals, telemetry data, aerodynamic processes, active media, and models of stochastic minelike objects.

Achievements

• Investigated chaotic behavior in systems with delayed feedback, identified different forms of instability, and studied the influence of delay time on temporal intermittency.

• Developed analytical approaches to averaging local functional matrices to improve the calculation of characteristic exponents.

• Developed a method for modeling the dynamics of topological instability in attractors reconstructed from time series, including estimation of optimal embedding dimensions.

• Established the validity of fractal-analysis procedures through numerical calculations on multidimensional fractal attractors and real time series, including digitized electrocardiogram signals.

• Developed robust algorithms for fractal analysis of nonlinear and chaotic time series.

• Investigated self-organization processes in active media, particularly activator-inhibitor systems.

• Developed topological and locally asymptotic methods for reducing the computational effort and data requirements of attractor and time-series analysis.
