  • Alternative mechanisms of stochasticity in maps with discontinuities 
    Naydenov, S.V.; Tur, A.V.; Yanovsky, A.V.; Yanovsky, V.V. (Вопросы атомной науки и техники, 2001)
    The maps with discontinuities dynamic chaos research is made. The borders of stability and bifurcation of cycles cutting are obtained. The structure of the stable cycles tree is determined. A new mechanism of spontaneous ...
  • Geometric models of statistical physics: billiard in a symmetric phase space 
    Naydenov, S.V.; Yanovsky, V.V. (Вопросы атомной науки и техники, 2001)
    The billiard problem of statistical physics is considered in a new geometric approach with a symmetric phase space. The structure and topological features of typical billiard phase portrait are defined. The connection ...
  • Influence of melt convection on the dynamics and capture inclusions for growing oxide crystals by HDC 
    Naydenov, S.V.; Nizhankovskiy, S.V.; Tan′ko, A.V.; Grin′, L.A.; Baranov, V.V. (Functional Materials, 2015)
    The main properties of motion of gas-vapor bubbles and impurity inclusions in hydrodynamic flows are considered. It is founded the criteria for the formation of the defective areas for crystal growth of oxide crystals by ...
  • Polymorphous billiard as a new type of billiards with chaotic ray dynamics 
    Naydenov, S.V.; Maslovsky, Yu.N.; Yanovsky, V.V. (Вопросы атомной науки и техники, 2007)
    A new type of chaotic billiards is introduced. Unlike the known ones, it contains scattering as well as focusing regions of the boundary and has no neutral components. The dumbbell-like from polymorphous billiards family ...
  • Polymorphous billiard with chaotic beams dynamics 
    Naydenov, S.V.; Maslovsky, Yu.N.; Yanovsky, V.V. (Functional Materials, 2006)
    A new type of billiard is introduced - the one with chaotic beams dynamics. The dynamics of dumbbell-like polymorphous billiards family is studied. The chaotic behaviour of the beams and their uniform stationary distribution ...
  • The highly efficient gamma-neutron detector for control of fissionable radioactive materials 
    Ryzhikov, V.D.; Grinyov, B.V.; Onyshchenko, G.M.; Piven, L.A.; Naydenov, S.V.; Lysetska, O.K. (Functional Materials, 2014)
    Comparative measurements and analysis of detection efficiency of fast and thermal neutrons from ²³⁹Pu-Be source by heavy oxide scintillators (Z≥50) confirmed high detection efficiency (∼ 40-50 %). The most probable mechanism ...
