  • Acoustic-stimulated relaxation of GaAs₁₋хPх LEDs electroluminescence intensity 
    Konoreva, O.V.; Lytovchenko, M.V.; Malyi, Ye.V.; Olikh, Ya.M.; Petrenko, I.V.; Pinkovska, M.B.; Tartachnyk, V.P. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2016)
    The effect of ultrasonic (US) treatment on electroluminescence of initial and irradiated with 2-MeV electrons (Φ = 8.24·10¹⁴ e/cm²) GaAs-GaP LEDs grown on solid solution base was studied. It was found that luminescence ...
  • An advanced necessary test for convergent number series and some consequences 
    Mironenko, L.P.; Petrenko, I.V. (Искусственный интеллект, 2013)
  • A new representation of Lagrange’s theorem in differential calculus 
    Mironenko, L.P.; Petrenko, I.V. (Искусственный интеллект, 2014)
    It is found a new representation of the mean value Lagrange’s theorem in the differential calculus. Any function increment can be expressed through the derivatives in the ending points of a given closed interval. Mean ...
  • Classification of the necessary tests of convergence in the theory of numerical series 
    Mironenko, L.P.; Petrenko, I.V.; Vlasenko, A.Yu. (Искусственный интеллект, 2013)
    The paper suggests three types of the necessary tests for the convergence of numerical series with positive terms. It is shown that these tests are consequences of the limit test of comparison with respect to the ...
  • Degradation of electrooptical characteristics of serial GaP light-emitting diodes, caused by fast electrons 
    Konoreva, O.V.; Lytovchenko, M.V.; Malyi, Ye.V.; Petrenko, I.V.; Pinkovska, M.B.; Tartachnyk, V.P.; Shlapatska, V.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2015)
    The study of electrical and optical characteristics of GaP LEDs irradiated with electrons (E = 2 MeV, Ф = 0…10¹⁵ cm⁻²) was performed. Especial interest was focused on appearing of S-type instability in current-voltage ...
  • Low doses effect in GaP light-emitting diodes 
    Hontaruk, O.M.; Konoreva, O.V.; Malyi, Ye.V.; Petrenko, I.V.; Pinkovska, M.B.; Radkevych, O.I.; Tartachnyk, V.P. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2016)
    The paper is devoted to the electrophysical characteristics study of serial red and green GaP light-emitting diodes (LEDs) irradiated with low α-particles doses (Φ ≤ 10¹² cm⁻²). It was stated that radiation features of ...
  • Mironenko’s limit test for numerical and power series 
    Kaida, S.V.; Petrenko, I.V.; Mironenko, L.P. (Искусственный интеллект, 2014)
    The report describes the derivation and application of Mironenko’s test for series with positive terms. Mironenko’s test has the same limitations that have d'Alembert's ratio test and Cauchy's radical test. But in practical ...
  • Parametric equations of a plane and the problem of description of plane curves in space R³ 
    Petrenko, I.V.; Mironenko, L.P. (Искусственный интеллект, 2013)
    The aim of this article is the application of the parametric equations of the plane for the description of plane curves in space R³. It is found a simple way of parameterization of the plane, which allows you to enter a ...
