Building a framework is difficult. On the one hand, the framework needs to beflexible enough to cater to a wide variety of needs; on the other hand, it needs tobe solid enough that it doesn’t fall prey to the beast of complexity—the urge tomake it t
如果笔记本电脑被盗，能找回来的几率是非常小的。不过有了Prey，就可以给你的笔记本加上防盗追踪的功能。Prey是一个跨平台的软件，可以运行在Windows / Mac OS / Ubuntu / Linux操作系统上。 在安装prey后，如果小偷用你的笔记本上网，那么具有笔记本防盗功能的prey会自动把IP位址、桌面截图、座标位置等信息发到你的信箱里，而且能通过摄像头拍到小偷的猥琐长相。 使用方法见附件的文档说明。
Many species of owl, including the barn and barred owl, use both visual and bi-aural location to search for prey around dusk and at night. Their bi-aural location system has a maximum sensitivity between 3-6kHz although the hearing of the owl has an
The dynamical properties of a stochastic non-autonomous ratio-dependent predator– prey system are studied by applying the theory of stochastic differential equations, Itˆo’s formula and the method of Lyapunov functions. First, the existence, the uniq
Effect of prey refuge on the dynamics and equilibrium density of，马智慧，李自珍，In this paper, we use an analytical approach to study the dynamics of the simplest forms of refuge using by prey. Here we incorporate prey refuge in a widely known continuous mo
A mathematical model of a three species prey-predator system with impulsive control and Holling functional response，刘少英，Pei Yongzhen，In this paper, we investigate a three species prey-predator system with impulsive prey harvest and Holling type II fu
