SDN enabled space-terrestrial integrated network architecture of railway system by Yinglei TENG, Xin LI, Jian WANG, Bogen CAI, Mei SONG

“…In view of the current situation that it is difficult to guarantee the safe and reliable transmission of data with the poor geographical environment in the single standard train communication network,the communication needs of each business of the railway system were investigated and a space-terrestrial integrated network architecture based on software defined network (SDN) and network functions virtualization (NFV) was proposed.By focusing on the controller to manage the physical facilities,the architecture realized decoupling application and physical infrastructure.The design of the architectural details and the requirements of the agreement for the architecture in the functional requirements and the information flow were discussed.In the end,the performance comparison between the space-terrestrial integrated network and other single-system network coverage was given,problems remaining to be solved and some feasible solutions faced by the space-terrestrial integrated network were briefly discussed.…”

AN INCIPIENT FAULT DIAGNOSIS METHOD FOR ROLLING BEARING BASED ON MCKD AND LMD by SUN Wei, LI XinMin, JIN XiaoQiang, HUANG JianPing, ZHANG XianHui

“…Aiming at the problem that the Local mean decomposition（LMD） method is difficult to draw early weak fault,a fault diagnosis method for the roller bearing based on maximum correlated kurtosis deconvolution（MCKD） and LMD was proposed.Firstly,the fault signal was de-noised and meantime periodic impact components were enhanced by MCKD method,Then,that result is decomposed by LMD to get PF,the correlation coefficient between the PF and the signal is used as the standard of judgment,so that the redundant low-frequency PF can be rejected.Finally,the effective PF is selected to analyze the spectrum and extract the fault feature.The experiment of the simulation data and the actual roller bearing fault diagnosis data show that the method can effectively extract the feature frequency information of incipient fault and has a certain reliability.…”

Research on adaptive rate control algorithm for H.264 based on R-Q model by Xin-zi ZHENG, Bing-qing LUO, Zhi-xin SUN

“…The foundation theory of rate control theory in H.264 video coding standard was analyzed.The latest research work about rate control algorithm were summarized.On the basis of analysis.A novel frame-level rate control algorithm was proposed.Firstly,in order to reduce the inter-dependency between RDO (rate-distortion optimization) and rate control,a kind of two-stage rate control algorithm was presented.Secondly,to provide more accurate prediction of the frame complexity,instead of the MAD (mean absolute difference),bits information in the RDO-based mode decision process was employed to predict the frame complexity.Thirdly,a self-adaptive exponential R-Q model was proposed.The proposed rate control algorithm overcomes the disadvantages in the rate control precision and encoding performance of former algorithms.…”
