Firstly, coif4 wavelet is adopted to scale decompose ECG signals containing noises, secondly, the soft and hard threshold value quantify high-frequency coefficients of every scale, finally, the wavelet reconstructs high-frequency coefficients of every scale which are quantified by the threshold value to get ECG signals being filtering. Experiments show that Wavelet Transform has well real-time and good filtering effect, and it has more obvious advantages more than traditional methods.","PeriodicalId":331155,"journal":{"name":"2009 WRI World Congress on Software Engineering","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131698712","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 Grid Harvest Service, GHS, is one of non-dedicated computing grid scheduling systems; it has been widely used in Grid research field. The contribution of GHS is providing appropriate prediction for long-term applications different from AppLes which is designed for short-term predictions. GHS maps metatasks using the Min-Min algorithm in a uniform log-term application. Min-Min is a highly efficient algorithm in an uniform workload environment that leads to load unbalance and low performance when the workload is not uniform. In order to solve the problem, a novel task scheduling algorithm is proposed in this work, which is an adaptive task scheduling algorithm based on Min-Min and Max-Min (A-MM). A-MM merges the high efficiency of traditional Min-Min scheduling with load balance of traditional Max-Min scheduling. The simulation and experimental result show that A-MM has better performance and scalability than the Min-Min of GHS.","PeriodicalId":331155,"journal":{"name":"2009 WRI World Congress on Software Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129035142","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}

Web service composition is the hotspot research in the field of Web services. Because the validity is a key requirement in the description of Web service composition, a formal language XYZ/ADL is introduced which describe the composition from the view of architecture. In this paper, we define a mapping from XYZ/ADL to a more practical approach of Web service composition BPEL4WS which is difficult to verify the validity of the composition. First, define the conversion of XYZ/E to BPEL4WS, analyze the similarity between the design elements in XYZ/ADL and activities in BPEL4WS, and then do the conversion of XYZ/ADL to BPEL4WS.","PeriodicalId":331155,"journal":{"name":"2009 WRI World Congress on Software Engineering","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128778208","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 complication of decompile was increased through block cryptosystems that convert the output of the opaque predicates into the corresponding judge conditions.","PeriodicalId":331155,"journal":{"name":"2009 WRI World Congress on Software Engineering","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125569714","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 standard independent component analysis algorithm require that the number of sensors is more than or equal to that of sources, so it is impossible to apply independent component analysis to single channel image denoising directly. In this paper, a single channel image denoising algorithm is proposed by constructing a noise image to as another observation signal for single channel noise reduction based on independent component analysis, thereby noise and original image can be separated through independent component analysis. Simulation result shows that much better denoising effect and signal-noise ration can be obtained by using this algorithm.","PeriodicalId":331155,"journal":{"name":"2009 WRI World Congress on Software Engineering","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126362240","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}
