  • Separation factors at sublimation refining of some lanthanides 
    Кravchenko, А.I. (Вопросы атомной науки и техники, 2020)
    It is shown that the application of ideal separation factor in calculations of sublimation refining of Sm, Eu, Tm, and Yb has confined character: in considered base–impurity systems a difference between effective (β) and ...
  • Separation of electroencephalogram low-frequency components on the basis of the stochastic resonance effect 
    Kharchenko, O.I.; Lonin, Yu.F.; Zabrodina, L.P.; Kartashov, V.M. (Вопросы атомной науки и техники, 2021)
    The paper describes the method for electroencephalogram (EEG) analysis based on the stochastic resonance (SR) effect. The numerical computation has provided the separation of low frequency components that fall within the ...
  • Separation of negative hydrogen ions from penning discharge with metal-hydride cathode

  • Separation of Variables and Contractions on Two-Dimensional Hyperboloid 
    Kalnins, E.; Pogosyan, G.S.; Yakhno, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    In this paper analytic contractions have been established in the R→∞ contraction limit for exactly solvable basis functions of the Helmholtz equation on the two-dimensional two-sheeted hyperboloid. As a consequence we ...
  • Separation of Variables and the Geometry of Jacobians 
    Hurtubise, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    This survey examines separation of variables for algebraically integrable Hamiltonian systems whose tori are Jacobians of Riemann surfaces. For these cases there is a natural class of systems which admit separations in a ...
  • Separation of variables in the two-dimensional wave equation with potential 
    Zhdanov, R.Z.; Revenko, I.V.; Fushchych, W.I. (Український математичний журнал, 1994)
    The paper is devoted to solution of a problem of separation of variables in the wave equation utt−uxx+V(x)u=0. We give a complete classification of potentials V(x) for which this equation admits a nontrivial separation of ...
  • Separation on velocities of the particles trapped in self-consistent Malmberg-Penning trap 
    Tarasov, I.K.; Maslov, V.I.; Tarasov, M.I.; Volkov, E.D. (Вопросы атомной науки и техники, 2005)
    Coherent structures and conditions of their occurrence in holding configurations have recently attracted the attention of many physicists working on nuclear fusion and nonlinear processes in plasma. Here we discuss the ...
  • Separation problem for a family of Borel and Baire G-powers of shift measures on R 
    Zerakidze, Z.; Pantsulaia, G.; Saatashvili, G. (Український математичний журнал, 2013)
    The separation problem for a family of Borel and Baire G-powers of shift measures on R is studied for an arbitrary infinite additive group G using the technique developed in [Kuipers L., Niederreiter H. Uniform distribution ...
  • Sequential implantations of deuterium and helium ions into tungsten-coated composite structures 
    Azarenkov, N.A.; Bobkov, V.V.; Tishchenko, L.P.; Starovoitov, R.I.; Kovtunenko, Yu.I.; Logachev, Yu.E.; Gamayunova, L.A. (Вопросы атомной науки и техники, 2016)
    The trapping and thermal desorption of deuterium and helium implanted into tungsten-coated composite structures were studied. The amount of accumulated deuterium and helium, and the shape of thermal desorption spectra were ...
  • Sergei Nikolaevich Chernikov. Memoirs 
    Plotkin, B. (Algebra and Discrete Mathematics, 2012)
    Dedicated to the 100th anniversary of the birth of Sergei Nikolaevich Chernikov.
