  • Azamat, Daiana (Nazarbayev University School of Science and Technology, 2019-05-06)
    This thesis consider three type of epidemiological models: SIR, SIS and SIRS with nonlinear incidence rate and piecewise constant delay of generalized type. In this paper the total population size is varied with time elapse. ...
  • Begzhigitov, Madi (Nazarbayev University School of Science and Technology, 2019-04-29)
    It is important to estimate the natural frequencies of the structural elements in the design of mechanical or electromechanical structures. There is a wide use of single lumped-parameter spring-mass models in the industry ...
  • Tabarek, Rysbergen (Nazarbayev University School of Science and Technology, 2019-04-19)
    In this thesis we propose and study an efficient iterative multigrid method for the time independent modified mild slope equation with and without energy dissipation term. The algorithm relies on a multigrid method ...
  • Yerzhigit, Bauyrzhan (Nazarbayev University School of Science and Technology, 2019-04-29)
    With the recent interest in knots, it is interesting to study their complexification. We have chosen to study Legendrian knots as they have the property that we can reconstruct the original knot from its projection. This ...
  • Yeleussinova, Meruyert (Nazarbayev University School of Science and Technology, 2019-05-03)
    This work deals with an application of pulse vaccination for a varying size of the population of time-delayed 𝑆𝐼𝑅𝑆 epidemic model. The dynamics of the infectious disease depends on the threshold value, 𝑅0, known as ...
  • Zharas, Banu (Nazarbayev University School of Science and Technology, 2019-05-01)
    In recent years, the study of synchronization of coupled oscillators have been the subject of intense research interest, leading to many new and unexpected phenomena. Our research is first focused on the analysis of a ...
