  • An SEIRS epidemic model with stochastic transmission 

    Witbooi, Peter J. (Springer, 2017)
    For an SEIRS epidemic model with stochastic perturbations on transmission from the susceptible class to the latent and infectious classes, we prove the existence of global positive solutions. For sufficiently small values ...
  • An unconditionally stable nonstandard finite difference method applied to a mathematical model of HIV infection 

    Obaid, Hasim; Ouifki,Rachid; Patidar,Kailash (De Gruyter Open, 2013)
    We formulate and analyze an unconditionally stable nonstandard finite difference method for a mathematical model of HIV transmission dynamics. The dynamics of this model are studied using the qualitative theory of dynamical ...
  • Multiplication of Crowns 

    Witbooi, Peter J. (Instituto de Matematica de Bahia Blanca (INMABB-CONICET), 2013)
    It is known that the only nite topological spaces that are H-spaces are the discrete spaces. For a nite poset which is weakly equivalent to an H-space, a generalized multiplication may be found after suitable ...
  • Fifth order two-stage explicit Runge-Kutta-Nystrom method for the direct integration of second order ordinary differential equations 

    Okunuga, S.A.; Sofoluwe, A.B.; Ehigie, J.O.; Akanbi, M.A. (Academic Journals, 2012)
    In this paper a direct integration of second-order Ordinary Differential Equations (ODEs) of the form using the Explicit Runge-Kutta-Nystrom method with higher derivatives is presented. Various numerical schemes are derived ...
  • Numerical treatment of Kap's equation using a class of fourth order method 

    Akanbi, M.A.; Okunuga, S.A.; Sofoluwe, A.B. (Academic Journals, 2011)
    Kap's equation is a stiff initial value problem. This paper deals with the treatment of Kap's equation using a class of 4th order explicit Runge-Kutta method. Numerical computation was carried out using Microsoft Visual ...
  • An assessment of the age reporting in Tanzania population census 

    Mwambene, Eric; Susuman, A. Sathiya; Hamisi, Hamisi F.; Lougue, Siaka; Regassa, Nigatu; Ogujiuba, Kanayo (Academic Research Publishing, 2012)
    The objective of this paper is to provide data users with a worldwide assessment of the age reporting in the Tanzania Population Census 2012 data. Many demographic and socio-economic data are age-sex attributed. However, ...
