    Global stability of a multi-group model with vaccination age, distributed delay and random perturbation by Jinhu Xu, Yicang Zhou

    Published 2015-05-01
    “…A multi-group epidemic model withdistributed delay and vaccination age has been formulated and studied.Mathematical analysis shows that the global dynamics of the model is determinedby the basic reproduction number $\mathcal{R}_0$:the disease-free equilibrium is globally asymptotically stable if $\mathcal{R}_0\leq1$,and the endemic equilibrium is globally asymptotically stable if $\mathcal{R}_0>1$.Lyapunov functionals are constructed by the non-negative matrix theory and a novel grouping techniqueto establish the global stability.The stochastic perturbation of the model is studied and it is provedthat the endemic equilibrium of the stochastic model is stochastically asymptotically stablein the large under certain conditions.…”

    MATHEMATICAL MODEL OF LOOSELY-COUPLED INERTIAL–SATELLITE AIR NAVIGATION COMPLEX by D. A. Sakharuk

    Published 2013-06-01
    “…The paper considers a mathematical model of loosely-coupled inertial-satellite navigation complex which has been developed in the class of linear discrete stochastic models. A specific feature of the considered algorithms for integration of navigation data is the possibility to use parametrical optimum evaluation of the linear Kalman filters constructed on the basis of equations. …”
