Because noise may degrade the quality and the intelligibility of speech, various enhancement technologies are applied in speech processing systems. The speech enhancement method in AMR is based on masking properties of the human auditory system, which performs a comb filter before the open loop pitch analysis. During the entire processing course, the filter is employed. While for the unvoiced part, it may degrade speech quality. In view of the energy of the speech, the paper improves this step by using perceptual weighting filter on voiced speech so as to strengthen pitch and harmonic components and suppress the noise because of its periodicity character. The experiment results indicate that the method can improve the quality and intelligibility of the speech while take less computation load.","PeriodicalId":268670,"journal":{"name":"2009 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126410057","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}

To solve the data integration problem in current business systems, a dynamic data integration model based on SOA is proposed. This model which is dynamic and application oriented extends data source to application oriented, component oriented or even service oriented new data source. The model provides a service oriented architecture model for the integration of heterogeneous and heterotypic data and data sharing. Thus data from each business system can easily be integrated and shared. Cross-platform integration of data resource is realized.","PeriodicalId":268670,"journal":{"name":"2009 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123008578","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}

Scholars believe that the establishment of strong customer relationship should be an important means for an enterprise to gain competitive advantage. Enterprises hope the customers can take the largest benefits from the relationship. Customer sex types have significant correlation with relationships, different sex types customers have different benefits preference. This paper firstly explores the basic dimensions of relationship benefits in services markets based on literature review for the past years, then analyzes the relationship benefits preference of different sex type customers. Finally, this paper proposes a relationship benefits management strategy. The findings of this paper are directions for future research and managerial implications.","PeriodicalId":268670,"journal":{"name":"2009 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125711948","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}

Those traditional music charts do not work well with the popularity of musical recordings nowadays because of huge impact of internet over music industry. A new kind of music charts is more and more popular, by which we call it as search charts or hit charts. In this paper, we choose this special music hit charts to study. First we took a series of analysis on the characteristics of music hit charts. Those characteristics of music hit charts are special thanks to the online user behaviors. Then we proposed a novel music categorization method on the basis of online user behaviors. The criterion of our method is to judge the popularity of each song with the variance of hits. In traditional commercial charts, music charts is influenced with economy. Our studies weaken the economy's influence over music popularity.","PeriodicalId":268670,"journal":{"name":"2009 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"627 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116733511","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}
