The environment of information dissemination is represented by complex network. The information here can represent viruses in the network, advertisements, hot topics, public opinions , rumors and so on. A new mathematical model describing the propagation process of information in the complex network is proposed using multi-agent simulation and discrete event simulation methods. The model is developed...
Qualitative reasoning uses incomplete knowledge to compute a description of the possible behaviors for dynamic systems. For standard QSIM algorithm frequently results in a large number of incomprehensible behavioral descriptions and the simulation for complex systems frequently is intractable, model decomposition methods are used to decompose the complex system model into simple sub-models. Qualitative...
Evacuation simulation can greatly ease the cost of money and material in fire case by using computer. Integrating ABM and GIS technology can not only recurrent the evacuation process, but also analyse optimal evacuation route, optimize the supermarket layout by GIS spatial analysis functions. A model is used to determine the action rules of evacuation staff, simulate the evacuation process on Agent...
A simplified simulation approach has been introduced for gated field emitters. F-N equation fitted with experimental field emission characteristic is used to calculate the characteristics of a double-gated field emitters. By assuming the cathode is a flat thin film, the anode current and gate current are simulated. The validity of the simulation is evaluated by experimental results.
According to a theories of electromagnetism, the electric field and heat generation density distribute affected by the electrode immersion depth was studied in process of electroslag remelting (ESR). The self-adapting meshing method was adopted. The result show that different electrode immersion depth lead to obvious dissimilarity for the electric field and heat generation density distribute. Based...
This paper presents the lateral position control of a moving web using a steering guide system in roll-to-roll (R2R) printed electronics. In typical R2R printed electronics processes, a web like plastic film runs through a long drying section where the lateral displacement of web is affected by the airflow in the dryer. In order to eliminate the lateral error, a steering guide can be used. We developed...
