This paper compared the landscape metrics derived from remote sensing data before and after Wenchuan earthquake. Firstly, two ASTER imageries acquired before and after earthquake were geo-referenced. Then, the two imageries were segmented and converted into vector files. Finally, six landscape metrics were computed using multi-resolution segmentation vector derived from the two imageries and the computation results before and after earthquake were compared. Comparing results, it concluded that the landscape metrics before and after earthquake are significantly different. After earthquake, the fine surface structure was destroyed due to numerous landslides and rockslides, so Perimeter Area Fractal Dimension and Splitting Index which represents shape complexity decreased. Perimeter Area Fractal Dimension and Splitting Index are more effective indexes to detect the land cover change before and after earthquake.","PeriodicalId":422513,"journal":{"name":"2009 First International Workshop on Education Technology and Computer Science","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129489481","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}

Firstly, in order to obtain the sub-band multi-wavelet coefficients, two multi-focus images are transformed by multi-wavelet. Then, the regional gradients of high-frequency sub-bands at the largest scale are calculated. Finally, the high-frequency multi-wavelet coefficients and low-frequency multi-wavelet coefficients of the fusion image are determined simultaneously by the principle which is called the direction consistency of regional gradients. This algorithm can avoid the inconsistency that the fusion multi-wavelet coefficients at the same point are extracted from the source image in the horizontal direction, and from the source image in the vertical direction. Experiments illustrated here indicate that the new algorithm not only retains the details and edge characteristics of the source images, but also enhances visibility and clarity of the fusion image.","PeriodicalId":422513,"journal":{"name":"2009 First International Workshop on Education Technology and Computer Science","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129494683","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}

It differs from the other existing systems mainly in that it adopts a novel marking mechanism. It combines static analysis with dynamic testing to analyze students’ programs. So it can evaluate not only the testing results but also the constructs of the programs. It can give reasonable marks to programs with syntactical or logical errors. AutoLEP has been used in the C programming course since 2004 at Harbin Institute of Technology. The advantages of using AutoLEP are that the students are assessed on what they have to do in practice, rather than on their theoretical knowledge, and that the marking load on the examiner is drastically reduced.","PeriodicalId":422513,"journal":{"name":"2009 First International Workshop on Education Technology and Computer Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129840188","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 overall average technical efficiency is estimated to be 0.51 for the coal industry of China. The empirical results suggest the average efficiency is low.
