Witryna26 lut 2024 · AIA 131 Å images at three times (two from before the impulsive phase, one from the impulsive phase). The image on the left-hand side shows a snapshot from the time interval that was analyzed in the present study. 40%, 70%, and 90% contours from a RHESSI CLEAN image are given in four energy bands: 7–8 keV (red), 13–14 keV … 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

Witrynathe energy release site. Mathematical models and data correlations for ideal blast waves (Baker, 1973) show that blast wave pressure and impulse both vary as distance divided by the one-third power of the blast wave energy. The nondimensionalized distance of a target from the energy release center is given by R = R(p 0/E)1/3 [C.1] WitrynaUniversity of Pretoria Witryna15 sie 2024 · Indeed, impulsive control dynamical systems are used for the mathematical simulation of processes which are subject to impulses during their … tts launch pad
