In this paper, one investigates the dynamic behaviors of one-prey multi-predator model with Holling type II functional response by introducing impulsive biological control strategy (periodic releasing natural enemies at different fixed time). By using Floquet theorem and small amplitude perturbation method, it is proved that there exists an asymptotically(More)
In this paper, two integrated pest management models are investigated, which rely on release of infective pest individuals and of natural enemies in a constant amount, together with spraying of pesticides. It is proved that the susceptible pests can be eradicated if the release amount of infected pests is above some threshold or the pesticide effect is(More)
An impulsive delayed chemostat model with seasonality is formulated and analyzed. By introducing two thresholds, we obtain sufficient conditions for permanence of the system. It is shown that the conditions depend on time delay for the permanence of the model. Numerical results show that the system we considered has complex dynamics and the results we(More)
Although sex of prey is an important factor for the risk of predating, few articles consider the consequences of sexual favoritism and the corresponding effects on the impulsive predator-prey dynamics and its utility in biological control. This paper investigates the pest management strategy of a prey-predator system model with sexual favoritism. An(More)
We propose an enhancement to the method for lossless compression of hyperspectral images using two-stage prediction (IP3-BPS). The original IP3-BPS method used a two-stage predictor. The stage-1 predictor took advantage of spatial data correlation and formulated the derivation of a spectral domain predictor as a process of Wiener filtering. The stage-2(More)
