This paper presents a chaotic analysis method based on adjacent data dependence, which is based on the distance change between adjacent data. The method converts complex one-dimensional raw data columns into new adjacent distance value sequences to avoid phase space reconstruction. In this paper, several typical chaotic models are analyzed to illustrate the effectiveness of the proposed method. Finally,...
In this paper, we propose a new role analyzing paradigm for social networks enlightened by topic modeling, which can be adopted as a primitive building block in various security related tasks, such as hidden community finding, important person recognizing and so on. We first present the social network under analyzing as a heterogeneous network constructed by both the users and the subjects discussed...
Topic modeling is a popular text mining technique for extracting latent semantics from text. It can be widely applied in intelligence analyzing, anti-terrorist, and various other security related tasks. Most existing topic models only focus exclusively on the text literally, and disregard rich contextual, cultural, and language background, hindering the understanding and discovering of the key clues...
With the increasingly serious situation of global warming, governments all over the world have adopted various carbon emission policies to strengthen the carbon regulation to enterprises and supply chains. This paper builds a supply chain (two-echelon supply chain, one producer and one retailer) carbon emissions model based on the theory of System Dynamics. We introduce the carbon emission polices...
The exploitation of coastal beach plays a great role in promoting the development of local economy. The employment of different development modes of coastal beach will in different degrees influence local resources, environment, ecosystem stability, economic and social development and so on. Therefore, the choice of a scientific and rational model is particularly important to the exploitation of coastal...
Dynamic characteristic of a cracked rotor has been theoretically studied by many researchers. In this paper, the virtual prototype model of the rigidity-supported rotor system with a transverse crack is built by dynamic simulation software ADAMS. Furthermore, the vibration characteristics are studied by time and frequency domain analysis based on virtual prototyping simulation through setting different...
Rotor unbalance is the main vibration excitation source of rotating machinery accounting for 60~70% of the total machine fault. In this paper, unbalance fault and dynamic balancing are simulated by the virtual prototyping technology based on the unbalance mechanism and balancing theory. The single-face and double-face dynamic balancing are studied. The results validate the correctness and feasibility...
This paper presents a component management system framework of component library in credit evaluation domain(CL-I). In order to share component resource among different component libraries, this paper proposes a general interoperable model based on software adapter. Facet classification schema is used for the classification representation of credit evaluation component and the term space for faceted...
