Migration method in domain of seismic techniques is effective to locate and reshape the objects. Kirchoff migration method is based on electromagnetic wave equation. It is an accurate calculation method. Kirchoff migration method has widely adaptabilities with different horizontal and vertical velocity of electromagnetic wave, and the computation time is acceptable. In this paper, migration imaging principle is been introduced at first, then Kirchoff migration method is been discussed. By dealing with GPR simulation and experiment image, it shows that the Kirchoff Migration method used in GPR imaging is effectiveness and stability.","PeriodicalId":132465,"journal":{"name":"2012 International Conference on Computer Science and Electronics Engineering","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129104528","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}

Based on removing high frequency noise in wavelet analysis, the PCA algorithm is used to process the EEG signals to reduce the data dimension. Then, the DEBSS algorithm is adapted to separate the EEG signals which data dimension has been reduced. The main interference is identified and removed by using cross-correlation coefficient and related non-linear parameters to analyze the independent components. Finally, through reconstructing the remaining independent components, the EEG signals without main interference will be obtained. The experimental results show that this method can eliminate the main interference of multi-channel EEG signals rapidly and effectively, meanwhile, it is stable and has strong scalability.","PeriodicalId":132465,"journal":{"name":"2012 International Conference on Computer Science and Electronics Engineering","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123619992","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}

GIS raster data has amount of data, so when a large number of users access, traditional file mapping and network database, etc will have problems such as server overload, lower sharing efficiency. Cloud computing is undoubtedly the best ideas to solve storage and display of huge amount of raster data. At present, managing and display raster data on the public cloud platform have developed methods and techniques, in which Google Earth is one of the best. But using public cloud to manage massive raster data within the enterprise, it will bring security issues such as leakage of confidential data, so we need to build private clouds under LAN environment for enterprises. This paper, first, discussed the internal private cloud framework and the design of distributed file system under the LAN environment, and analyzed how to storage image pyramids for raster data in the distributed file system, and then proposed the Map/Reduce technology based on G/S mode, to achieve load balancing strategy for data download. Studies show that the private cloud framework in this paper, the grid download ability continuously improved, as the data nodes increases, it can meet internal management and shared purpose of raster data, the research results have a theoretical value and practical significance.","PeriodicalId":132465,"journal":{"name":"2012 International Conference on Computer Science and Electronics Engineering","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114536882","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 basic idea is that firstly get a coarse estimation by using the peak of a period gram and then gain an accurate estimation by using a new interpolation formula about the two lines beside the pea. Next, using the frequency as guide frequency, to control the frequency of the sine signal produced by the NCO (Numerically Controlled Oscillator). And finally achieve the goal of carrier synchronization through the adaptive algorithm of the PLL. With the method of real-time and precise estimation of carrier, it can reduce the tracking time in low signal-to-noise rate and high dynamic condition. The results show that it can effectively achieve the expectations of carrier quickly capture and carrier accurate tracking.","PeriodicalId":132465,"journal":{"name":"2012 International Conference on Computer Science and Electronics Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114768898","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 this paper, a new framework of the next generation power communication transmission network based on Packet Transport Network (PTN) and Optical Transport Network (OTN) is proposed. Furthermore, strategies for interconnection and evolution of the current and future transmission network are discussed. The conclusion is that the PTN and OTN based network can solve the problems of traditional MSTP and DWDM network, so it is a suitable scheme for the next generation power communication transmission network.","PeriodicalId":132465,"journal":{"name":"2012 International Conference on Computer Science and Electronics Engineering","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114858449","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}
