    Optimal control of phytoplankton–fish model with the impulsive feedback control

    Considering how to exploit the lake resource reasonably, we propose a phytoplankton–fish model with the impulsive feedback control and investigate the sufficient conditions for the existence of the order-1 per...

    Nonsynchronous bifurcation of SIRS epidemic model with birth pulse and pulse vaccination

    In this paper, we construct an SIRS epidemic model with birth pulse and pulse vaccination at the different fixed moment. The stability of the infection-free periodic solution is obtained by using the Poincaré ...

    Bifurcation and chaos of biochemical reaction model with impulsive perturbations

    In this paper, a biochemical model with the impulsive perturbations is considered. By using the Floquet theorem for the impulsive equation and small-amplitude perturbation skills, we see that the boundary-periodi...

    The effect of pulsed harvesting policy on the inshore–offshore fishery model with the impulsive diffusion

    In this paper, we propose the inshore–offshore fishing model with impulsive diffusion and pulsed harvesting at the different fixed time. The existence and globally asymptotical stability of both the trivial pe...

    Nonlinear modelling of chemostat model with time delay and impulsive effect

    In this paper, a chemostat model with periodically pulsed input and time delay is considered. We show that there exists a microorganism-free periodic solution, which is globally attractive when the period of i...

    A new shell casting process based on expendable pattern with vacuum and low-pressure casting for aluminum and magnesium alloys

    A new shell casting process, with the adoption of the foam pattern of lost foam casting (LFC) as prototype and the combination of the thin shell fabrication technology of investment casting and vacuum and low-...

    Chemical chaos in enzyme kinetics

    In this paper, the effect of impulsive perturbation on enzyme kinetics is investigated. The impulsive perturbation is affected by introducing periodic constant input. The dynamical behavior of system is simula...
