Data:
V.N.Sidorets was born
on July 22, 1956 in Kiev. He received his B.S. degree from the Physics
Faculty of the Kiev State University in 1978. He has been working
at the Paton Welding Institute, National Academy of Sciences of Ukraine
since 1980. Currently, he is senior research stuff of High Voltage
and Laser Equipment Department. He received his Candidate of Technical
Scienses degree (Ph.D) in 1992. He has published over 70 scientific
paper, including foreign patents. The papers are maily devoted to
simulation of electric arc, nonlinear electric circuits with arc,
its stability, periodic and chaotic oscillations which occur in this
circuits. Area of interests: simulation of electric arc, chaos in
nonlinear electric circuits with arc, techniques for nonlinear circuit
research.

Research & Development
Activity:
- The model
of dynamical electric arc was developed. This model describes the
statical and dynamical properties of arc and allows to simulate
the arc as the part of electric circuits. It can describe the arc
applied for welding: argon arc, CO2 arc, plasma arc,
arc moving in magnetic field, etc.
- Existance
of periodic and chaotic oscillations in electric circuits with arc
was proved. Its properties was studied by methods of bifurcation
theory, quality theory of ordinary differential equations, catastrophe
theory.
- The methods
and techniques for investigation of nonlinear systems was developed
including: Numerical solving of differential equations with displaying
on phase space; Finding the periodic solutions of differential equations
(stable and/or unstable); Calculation of multiplicators of periodic
trajectiories; Obtaining Poicare section of strange attractors;
Construction of bifurcation diagram; Construction of iteration maps;
Construction of bifurcation curves in parameter's plane.
