A physical protection system (PPS) is used to protect a nuclear power plant (NPP) for preventing the nuclear material and critical infrastructure from theft, robbery, illegal transfer, and sabotage. An integrated platform for analysis and design (IPAD) of PPS was proposed by the authors’ previous work. By combining the functions of 3-D modeling of PPS with automatic 2-D design drawing generation,...
This paper proposes a new classification algorithm for quantitative investing multi-factor model. The proposed algorithm is derived from the Information Bottleneck (IB) clustering method. To achieve the goal of categorize stock objects into different class of price changes, two procedures are introduced into the original IB algorithm. By the aid of merging an unknown object into training samples,...
Based on modeling method of the train operation system by hybrid Petri nets, we define a train speed adjustment process model and analyze the adjustment process by two examples. Comparing with existed analysis, our analysis can describe two relationships quantitatively: one is the relationship between discrete events and continuous variables, another is the relationship among different variables in...
