A new denoising method for heart sound signal based on wavelet transform is proposed. First of all, the information signal is transformed by multi-scale wavelet. The wavelet coefficients of each scale indicate a distribution sequence of probability according to the corresponding wavelet entropy threshold to find the maximum entropy of wavelet on certain interval, and the interval is recognized as the leading range of noise. And then, a fixed threshold denoising method is used to adaptively enhance the judgment about absolute value with larger attenuation wavelet coefficients, which can reduce the high frequency sound signal loss and improve the heart sound signal to noise ratio. The denoising simulation experiment is carried out to test the performance. The result shows that the proposed method can improve the output signal to noise ratio of heart sound signal, reducing the influence of noise on the extraction of heart sound signal, and therefore, the noise elimination algorithm has stronger anti-interference ability and superior performance.","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121260556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this paper is to carry out safety analysis on Regional Data Center (RDC) and the core trackside equipment of CTCS-1 to identify potential hazards and generate Safety Design Demand (SDD) to provide safety guidance for system design. In view of the complicated interaction among the subsystems of CTCS-1, System-Theory Process Analysis (STPA) is adopted and appliedin the system. Taking the sending of Temporary Speed Restriction (TSR) from RDC to the On-board Equipment (OBE) as an example, the safety analysis is carried out by following the STPA process to identify the related systemic unsafe factors and the related requirements and generate SDD. Based on the SSD identified in the STPA, this paper carries out the modelling and verification for the safety critical component of CTCS-1 system via the UPPAAL model checker. The analysis results show that the STPA is suitable to discover the key factors and safety hazards of train control system and the preventive measures can be adopted to prevent the design defects and safety hazards in the early stages of system design.","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125034137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A tail frequency model that based on the crucial characteristic points of fish is proposed for detecting the tail frequency of the fish in real-time. Firstly, the target image is detected through image processing algorithm, and the binary image of the fish target area is obtained; then, according to the physical and tail characteristics of fish, the coordinate of centroid, tail point, head and other key points are obtained. The geometric model of the fish tail angle is established. Finally, the change rule of the tail frequency of the fish is obtained by the analysis of the fish tail angle in the continuous video frame. The experiments show that the fish tail characteristics in the single image can be effectively obtained and the fish tail frequency in pH = 7 (normal water quality), pH = 5 (abnormal water quality), pH = 3 (water quality deterioration) are consistent with the observed change rule of the tail frequency. The fish tail frequency characteristics can be effectively identified by the proposed model, and the theoretical basis and experimental method are provided for further studying about biological water quality.","PeriodicalId":267944,"journal":{"name":"2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC)","volume":"22 13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116553260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
