Current methods don't make full use of censor information, and only use the positions or sequence of censors, not the exact times. In the paper, a modified method has been used to combine non-parametric and parametric features, and made fully use of the censor information. Thus, more accurate and practical results were obtained. An engineering calculating example shows the fine performance of the method and the results are practical.","PeriodicalId":207692,"journal":{"name":"2010 The 2nd Conference on Environmental Science and Information Application Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122161119","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}

Monitoring and early warning are the main means to effectively reduce the harm of landslide disaster. Different from the traditional method of monitoring, differential interferometry synthetic aperture radar (D-InSAR) measuring technique has the advantage of detecting and penetrating earth surface in all weather conditions and in all time, obtaining continuous and large-area deformation information. Taking the Jinpingzi Landslide of Jinshajiang valley as the research object. The monitoring technique of three orbits difference, the basic method of D-InSAR, is used to obtain surface deformation value. Research results show that the deformation value of Landslide boundaries is larger than the surrounding area, and the D-InSAR technology is a feasible approach for monitoring landslide.","PeriodicalId":207692,"journal":{"name":"2010 The 2nd Conference on Environmental Science and Information Application Technology","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121363659","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}

(2) The adsorption process of NH4+ on aged refuse is spontaneous and exothermic. Temperature is conducive to the spontaneous adsorption but adsorption decreased.

The results show that the eccentricity of the diversion wall will improve on the low water flow areas behind wall and eliminate sludge deposition. With the increase in the eccentric value diversion, the second low-velocity flow area behind radial wall will be formed. Comparing different the velocity curve of eccentricity in the oxidation ditch, the eccentricity of the diversion wall should be set up between the 0.3m∼0.4m.

The region of interest (ROI) of a host image was selected by an image energy function, and the fragile watermark was embedded in ROI through quantizing the middle coefficients. Based on visual masking, the robust watermark was embedded in non-ROI. While the extraction of robust watermark needed the secret key and the seams, the fragile watermark extraction just needed the seams. The experimental results illustrate that the fragile watermark is weak against many kinds of attack, which can be used to determine whether the ROI is attacked, and that the robust watermark can resist image processing operation, adding noise, JPEG and RML.","PeriodicalId":207692,"journal":{"name":"2010 The 2nd Conference on Environmental Science and Information Application Technology","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124742616","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}
