• Modelling and optimal control of pneumonia disease with cost-effective strategies 

      Tilahun, Getachew Teshome; Makinde, Oluwole Daniel; Malonza, David (Informa UK Limited, trading as Taylor & Francis Group, 2017)
      We propose and analyse a nonlinear mathematical model for the transmission dynamics of pneumonia disease in a population of varying size. The deterministic compartmental model is studied using stability theory of differential ...
    • Modelling and optimal control of typhoid fever disease with cost-effective strategies 

      Tilahun, Getachew Teshome; Makinde, Oluwole Daniel; Malonza, David (Hindawi Publishing Corporation, 2017-09)
      We propose and analyze a compartmental nonlinear deterministic mathematical model for the typhoid fever outbreak and optimal control strategies in a community with varying population.The model is studied qualitatively ...
