Based on an instantaneous linear mixing model, independent component analysis algorithm is used for separating interfering signals from observed signals. The influences of energy storage circuit elements such as capacitance are analyzed via numerical and experimental simulations. It is shown that, for circuits in which energy storage circuit elements perform less significant effects, relatively satisfied separation results of interfering signals can be obtained. On the other hand, in cases that energy storage circuit elements have significant effects, the separation results will deteriorate. Moreover, when a known input signal is enclosed in the observed mixtures, the separation results for interfering signals will be obviously improved.","PeriodicalId":404630,"journal":{"name":"Proceedings of 2013 2nd International Conference on Measurement, Information and Control","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128164755","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 calculation of normal working condition and malfunction condition of orifice plate, the relationship between deviation value of the orifice plate discharge coefficient and deposition degree have been concluded by CFD software. In order to implement online diagnosis, another detecting point is installed on downstream of the pressure detecting point of flange. The differential pressure ratio of factor (k) has been calculated which reflects the degree of distortion in flow field caused by deposition. Through analysis of simulation data, empirical formula about factor k with deposition degree Yu has been drawn. Through the formula, online diagnosis of deposition and correction of the measured value can be realized. Real flow experiments verify the effectiveness of the method and its practicability in engineering.","PeriodicalId":404630,"journal":{"name":"Proceedings of 2013 2nd International Conference on Measurement, Information and Control","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126859534","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}
