| 9 | A Hazard Assessment Method for Potential Earthquake-Induced Landslides – A Case Study in Huaxian County, Shaanxi Province显示文摘The hazard assessment of potential earthquake-induced landslides is an important aspect of the study of earthquake-induced landslides. In this study, we assessed the hazard of potential earthquake-induced landslides in Huaxian County with a new hazard assessment method. This method is based on probabilistic seismic hazard analysis and the Newmark cumulative displacement assessment model. The model considers a comprehensive suite of information, including the seismic activities and engineering geological conditions in the study area, and simulates the uncertainty of the intensity parameters of the engineering geological rock groups using the Monte Carlo method. Unlike previous assessment studies on ground motions with a given exceedance probability level, the hazard of earthquake-induced landslides obtained by the method presented in this study allows for the possibility of earthquake-induced landslides in different parts of the study area in the future. The assessment of the hazard of earthquake-induced landslides in this study showed good agreement with the historical distribution of earthquake-induced landslides. This indicates that the assessment properly reflects the macroscopic rules for the development of earthquake-induced landslides in the study area, and can provide a reference framework for the management of the risk of earthquakeinduced landslides and land planning. | LIU Jiamei GAO Mengtan WU Shuren WANG Tao WU Jian | 2016 | Acta Geologica Sinica(English Edition)2016，90，2： | 8 |

| 15 | Demodulation Based on Harmonic Wavelet and Its Application into Rotary Machinery Fault Diagnosis显示文摘The harmonic wavelet transform(HWT) and its fast realization based on fast Fourier transform(FFT) are introduced. Its ability to maintain the same amplitude-frequency feature is revealed. A new method to construct the time-frequency(TF) spectrum of HWT is proposed, which makes the HWT TF spectrum able to correctly reflect the time-frequency-amplitude distribution of the signal. A new way to calculate the HWT coefficients is proposed. By zero padding the data taken out, the non-decimated coefficients of HWT are obtained. Theoretical analysis shows that the modulus of the coefficients obtained by the new calculation way and living at a certain scale are the envelope of the component in the corresponding frequency band. By taking the cross section of the new TF spectrum, the demodulation for the component at a certain frequency band can be realized. A comparison with the Hilbert demodulation combined with band-pass filtering is done, which indicates for multi-components, the method proposed here is more suitable since it realizes ideal band-pass filtering and avoids pass band selecting. In the end, it is applied to bearing and gearbox fault diagnosis, and the results reflect that it can effectively extract the fault features in the signal. | MAO Yongfang QIN Shuren QIN Yi | 2009 | Chinese Journal of Mechanical Engineering2009，22，3： | 5 |

| 18 | IMPROVED METHOD FOR HILBERT INSTANTANEOUS FREQUENCY ESTIMATION显示文摘In the mechanical fault detection and diagnosis field,it is more and more important to analyze the instantaneous frequency (IF) character of complex vibration signal.The improved IF estimation method is put forward aiming at the shortage of traditional Hilbert transform.It is based on Hilbert transform in wavelet domain.With the help of relationship between the real part and the imaginary part obtained from the complex coefficient of continuous wavelet transform or the analyti- cal signal reconstructed in wavelet packet decomposition,the instantaneous phase function of the subcomponent is extracted.In order to improve the precise of IF estimated out,some means such as Linear regression,adaptive filtering,resampling are applied into the instantaneous phase obtained, then,the central differencing operator is used to get desired IF.Simulation results with synthetic and gearbox fault signals are included to illustrate the proposed method. | BO Lin LIU Xiaofeng QIN Shuren | 2007 | Chinese Journal of Mechanical Engineering2007，20，6： | 3 |
| 19 | Hidden Two-Stream Collaborative Learning Network for Action Recognition显示文摘The two-stream convolutional neural network exhibits excellent performance in the video action recognition.The crux of the matter is to use the frames already clipped by the videos and the optical flow images pre-extracted by the frames,to train a model each,and to finally integrate the outputs of the two models.Nevertheless,the reliance on the pre-extraction of the optical flow impedes the efficiency of action recognition,and the temporal and the spatial streams are just simply fused at the ends,with one stream failing and the other stream succeeding.We propose a novel hidden two-stream collaborative(HTSC)learning network that masks the steps of extracting the optical flow in the network and greatly speeds up the action recognition.Based on the two-stream method,the two-stream collaborative learning model captures the interaction of the temporal and spatial features to greatly enhance the accuracy of recognition.Our proposed method is highly capable of achieving the balance of efficiency and precision on large-scale video action recognition datasets. | Shuren Zhou Le Chen Vijayan Sugumaran | 2020 | Computers, Materials & Continua2020，，6： | 3 |
| 20 | Gabor Order Tracking Filtering Technology in Rotary Machinery显示文摘Order analysis is one of the most important technique means of condition monitoring and fault diagnosis for rotary machinery.The traditional order analyses usually employ the Vold-Kalman filtering,however this method is confined to the expensive hardware equipments.This paper starts from Gabor transform and applies the Gabor time-frequency filtering to vibration signal.The order component's time-frequency coefficients are extracted by mask operation.The order component is reconstructed from the obtained coefficients.The following four key technologies,such as smoothing rotary speed curve,defining filtering band width,constructing the mask operation matrix and reconstructing signal component,are also deeply discussed.Moreover,the technique to smooth the rotary speed curve based on polynomial approximation,the method to determine filtering band width,the arithmetic to constitute mask array and the iterative algorithm to reconstruct signal based on minimum mean square error are specifically analyzed.The 4th order component is successfully gained by using the methods that Gabor time-frequency filter,and the validity and feasibility of this method are approved.This method can solve the problem of order tracking filter technologies which used to depend on hardware and efficiently improve the accuracy of order analysis. | LI Ning QIN Shuren MAO Yongfang YANG Jiongming | 2010 | Chinese Journal of Mechanical Engineering2010，23，5： | 3 |
