Once it occurs, it often results in group bodied injuries and major economic losses, and the social impact is serious. Due to the disturbance of the surrounding soil caused by the shield construction, uneven settlement on the ground and protective measures were not developed in time and then evolved into high-accident, high-caused collapse accidents. In addition to the engineering geological conditions in the shield construction, the tunneling speed, cutterhead torque, soil warehouses pressure, simultaneous grouting amount, simultaneous grouting pressure, and other parameters in the shield construction are also the main factors affecting ground settlement. This paper analyzes the grey connection degree between the settlement monitoring of a metro shield construction and the shield construction parameters in a certain city. It is concluded that the most important factor causing ground settlement is the pressure of the earth storage, and corresponding preventive measures are proposed for the subsequent tunnel shield construction. It is instructive to reduce surface subsidence and prevent it from becoming a collapse accident.","PeriodicalId":6673,"journal":{"name":"2018 IEEE International Conference of Safety Produce Informatization (IICSPI)","volume":"4 1","pages":"16-19"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87972951","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}

In the Faculty of Engineering and the Built Environment, University of Johannesburg, South Africa, the Department of Electrical Engineering Science applied the continuous assessment in the past five years in order to achieve better study performance while the Departments of Mechanical Engineering Science and Civil Engineering Science are still using the traditional summative assessment. It is necessary to analyse the performance of these two different assessment methods to find which method is better or more stable. In this paper, the traditional summative assessment and the continuous assessment are investigated and compared based on the pass rate of the modules/subjects of these three departments. The histograms and Wilcoxon signed-rank test are used to analyse the differences of these two assessment methods. From the statistical results of this case study, the pass rate of the traditional summative assessment is more stable than the continuous assessment. Finally the unexpected performance of the continuous assessment is investigated.","PeriodicalId":6673,"journal":{"name":"2018 IEEE International Conference of Safety Produce Informatization (IICSPI)","volume":"46 1","pages":"531-535"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80434967","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}

Background subtraction method is one of the most commonly used methods for moving object detection, in which moving objects in image sequences are detected by comparison of the background model with the current frame. In the process of moving object detection, there are many challenges, such as the interference of clutter background, the influence of illumination, noise and shadow. In this paper, a novel Gaussian mixture model background subtraction method based on wavelet blocks is proposed for the challenge of object detection. This method can not only reduce the influence of illumination, noise and shadow, but also adapt to the dynamic change of natural scene. The contribution lies in the following aspects: (1) A Gaussian background modeling method with less running time is proposed in the background modeling stage. The background is reconstructed based on Gaussian mixture model (GMM) of the mean images of image blocks, aiming to simplify the calculations so as to improve the speed of the corresponding operations. (2) In the foreground detection stage, a wavelet-based de-noising method with the semi-soft threshold function is applied to de-noise the object images of the foreground. Experimental results show that the computational complexity is reduced, while the adaptability and performance are improved by using the proposed method. It was more efficient and robust than traditional approaches.","PeriodicalId":6673,"journal":{"name":"2018 IEEE International Conference of Safety Produce Informatization (IICSPI)","volume":"1 1","pages":"6-10"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91526482","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}
