In order to research the scattering characteristics of moving targets, a simulation method applied with quasi-static theory is proposed. Firstly, the CAD model of target is established and then the all-space static RCS database for this target is set up by electromagnetics software. Secondly, the flight track is established so that the real-time posture change can be described. The attitude angles...
A novelty method of face recognition combined with the fusion of local 2DGabor mean values and 2DPCA dimension deduction based on subspace analysis is proposed. Firstly, each facial image in the training sample set is divided according to the five special face regions and then the features of five key regions are extracted through 2DGabor wavelet, mean values are calculated from feature vectors gained...
Main defects about the slow speed of information exchange and the poor capabilities of the emergency response in the current ISCS (Integrated Supervisory Control System) of URT are described in this paper. Then an ISCS model with multi-layer transport hub based on Cyber Control software is constructed in laboratory. Combined with the characteristics of current ISCS networks, a multiple direction information...
As the development of technology and Internet, electronic publishing shows great strength in taking place of the traditional way, for its unique advantages. People are getting used to the electronic publishing and that brings huge space for its development.
Electronic publishing has been highly developed because of the clipping pace of the modern technology. And there is always the opinion that electronic publishing will take the place of the traditional way totally and be the perfect way to bring out knowledge. But as a study on its development, the scientists have successfully explored its deficits and worked on how to correct and further developed...
