This paper proposed a recommended method of standard bibliography based on topic model which fused multi-feature. Firstly, the LDA topic model was used to analyze the standard resource which user concerned, then the user attention model was created by combined with the user's information, Secondly, by analyze the feature of standard bibliography documents in attribute, classification and association...
In order to guarantee the safety operation of the SCADA system under network attack condition, it is important to construct an intelligent model on SCADA system including reasoning and judgment in network attack and defense. This paper describes the network attack knowledge based on the theory of the factor expression of knowledge, and studies the formal knowledge theory of SCADA network from the...
Double valves system simulation model is established in AMESim environment, By comparing with experiment, The simulation model can accurately predict injection characteristics of the double valves system. The influence of the parameters such as piston diameter, cam velocity, piston matching clearance, SV valve lift, NCV valve lift, needle valve lift and injector diameter on the main fuel injection...
The characteristic variability in gate-all-around (GAA) Si nanowire (NW) metal–oxide–semiconductor field-effect transistors (SNWTs) is analyzed and experimentally investigated in this paper. First, the main variation sources in SNWTs are overviewed, with the detailed discussion on the specific sources of NW cross-sectional shape variation, random dopant fluctuation in NW source/drain extension regions...
This paper has done some research on how to scientifically find the order parameters which influenced the supply chain system's collaborative operation. Besides revealing the thinking process of supply chain collaboration management, we tried to use simulation technology to build intelligent process simulation model of supply chain collaboration management. On this background, Model Drive Decision...
This paper puts forward the architecture of integrated virtual equipment simulation system based on the ideas of advanced manufacturing technology, and analyses the key techniques to be implemented among the system module. Taking use of the development kits, such as Open Inventor and Visual Studio.net, we have carried out the system that have the functions, including virtual assembly simulation, engineering...
It is the foundation of developing virtual prototype to construct assembly model. On the basis of that the advantages and disadvantages of the existing assembly model are pointed out through studying on relational models separately, a new virtual assembly model based on scene graphics technology of extensible group node, which is suitable to personal computer, is brought forward. Using this new scene...
