  • Effect of Loss of Vaccine Induced Immunity in the Transmission Dynamics of Childhood Disease 
    Mr I. G. Usman; S.T. Akinyemi; A. A. Ahiaba; Mr Y. Oyelowo (International Journal of Applied Science and Mathematical Theory, 2016-12-01)
    In this paper, a deterministic nonlinear model for the transmission dynamics of childhood disease is formulated and rigorously analyzed to explore the effect of loss of vaccine-induced immunity. The model was shown to ...
  • EFFECTS OF SENSITISATION AND EARLY TREATMENT ON FUTURE OUTBREAK OF LASSA FEVER IN NIGERIA 
    A. A. Ahiaba; Ibrahim M. O.; Ahiaba M. (Journal of Mathematical Sciences & Computational Mathematics, 2021-01)
    We exploit the dynamics of Lassa fever model with sex structure of the human population with the rat population. The objectives of the research were to: (i) solve for the equilibrium point of the disease free of the model; ...
  • OPTIMAL CONTROL OF LASSA FEVER QUARANTINE MODEL 
    Ibrahim M. O.; A. A. Ahiaba; S.T. Akinyemi (Journal of Mathematical Sciences & Computational Mathematics, 2021-01)
    In this paper, Optimal control is applied to a Quarantine Lassa fever model developed. The controls 𝑤1, 𝑤2 and 𝑤3 which represent Public education on lassa fever mode of transfer, use of Standard precautions in treatment ...
  • Series Solutions Using Variational Iteration, Differential Transform and Adomian Decomposition Methods. 
    A. A. Ahiaba; Ibrahim M. O. (International Journal of Academic Studies, 2018)
    In this research work, a proposed Lassa fever model is solved by the Differential transform method (DTM), Variational Iteration Method (VIM) and Adomian decomposition methods (ADM). Prior to approximate solutions to the ...
  • Stability Analysis for Gang Model 
    A. A. Ahiaba; Ibrahim M. O. (International Journal of Academic Studies, 2018-05-19)
    In this paper, criminal gang membership is treated as an infection that spreads through the host community by social contact. A mathematical model consisting of a system of coupled nonlinear ordinary differential equation ...
