Bursty topic detection method for microblog based on time series analysis by Min HE, Jie2 XU, Pan1 DU, Xue-qi1 CHENG, Li-hong WANG

“…Detecting bursty topics from microblogs was an important task to understand the current events attracting a large number of internet users.However,the existing hods suitable for news articles cannot be adopted directly for microblogs.Because microblogs have unique characteristics compared wi formal texts,including diversity,dynamic and noise.A detection method for microblog bursty topic was proposed based on time series analysis,which was an op-timization method of momentum model.The candidate bursty features were extracted by momentum model.The time se-ries of feature's momentum were modled by frequency domain analysis theory and stock trend analysis theory.The fre-quently pseudo-bursty features were filtered according to analysis results of frequency-domain characteristics.The inter-mittently pseudo-bursty features were filtered according to the novelty analysis result through stock trend theory.The bursty topics were finally emerged with combination of effective bursty features.The experiments are conducted on a real Sina microblog data set.It show that the proposed method improves the precis and F-measure remarkably compared with the momentum modle.…”

THERMAL DEFORMATION BEHAVIOR AND FLOW STRESS MODEL OF EH40 STEEL by JIN HeRong, DUAN ChangXin, DAI Chao

“…By analyzing the curve,we find that deformation temperature and strain rate all have important effects on the dynamic recrystallization and dynamic recovery of EH40 plate steel,increasing the deformation temperature or reducing the strain rate is conducive to the occurrence of dynamic recrystallization during deformation,which contributes to grain refinement of the material. A hyperbolic sine model with ZeneHollomon parameters is adopted,the thermal deformation equation,activation energy of thermal deformation,and mathematical model of Z parameters were obtained. …”
