Mathematical models have been published to investigated the effect of impulsive releases of sterile mosquitoes on mosquito-borne disease transmissions [6, 28,29,30,31,32,33,34,35]. Yu and Li obtained the existence and uniqueness of a periodic solution based on two switching subpopulations. Zobacz więcej Let \omega (t)=(x_1(t),x_2(t),y(t)) be any solution of system (1). Then the wild-mosquito-eradication periodic solution (0,0,y^*(t)) is globally asymptotically stable provided R_0<1,where and \theta =\displaystyle … Zobacz więcej If R_0>1 holds, then the wild mosquitoes are uniformly persistent, which implies there exists a positive constant \varsigma such that the solution (x_1(t),x_2(t),y(t)) of system (1) satisfies \displaystyle \liminf _{t\rightarrow … Zobacz więcej In the first case, we will give the proof of local stability of the wild-mosquito-eradication periodic solution. The local stability of the wild-mosquito-eradication periodic solution … Zobacz więcej If no dispersal happens in each patch, then wild mosquitoes will become extinct for R_{01}<0 and R_{02}<0, where R_{01}=b_1\theta … Zobacz więcej WitrynaThus impulsive differential equations, that is, differential equations involving impulse effects, appear as a natural description of observed evolution phenomena of several …

WitrynaView history In classical mechanics, impulse (symbolized by J or Imp) is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the resultant direction. smart driver for windowsWitryna21 gru 2024 · This paper proposes a prey-predator system with impulsive release of predator populations in polluted water.
