In this paper, we have investigated the spatial patterns in heterogeneous biological system by using a simple Turing model. Periodic external forcing is considered as the inhomogeneity. The formation mechanism has been analyzed. A variety of complex patterns including superlattice patterns can be induced. It is found that the intensity and the period of the external forcing play an important role...
In order to saving storage resource, a method of multicast duplicating based on ping pang switching mechanism is presented, switching the output role with the backup role of storage queue successively, guaranteeing the seamless switch of successive duplicate processes of the same packet, as well as the processes between two different successive packets, improving the efficiency of duplicating multicast...
Realizing the safe and economic operation of electric power system has great meaning to the development of country's economy, so the electric power technicians and scholars always pay much attention to the electric power market, security economic dispatch problem. Along with the development of power market, the safety and cost control faces many new problems: first, because of the asymmetry of the...
