In order to get the optimum working point that minimize the trade-off between the quality of the reconstructed signal, the time consumption and the hardware complexity when applying the perturbation signal to the system under test, the interaction between pertinent parameters is determined. These parameters are the number of the samples, the sampling frequency and the noise's level. The number of samples (N) is directly related to the memory's size of the hardware used in the measurement, the sampling frequency (Fs) is associated to the clock and the noise's level is affiliated to the algorithm or the measurement hardware. To achieve a good signal's reconstruction, the ratio (Fs/f) should be lower than (~2*N) and the window's size which is proportional to (N, Fs/f) as large as possible.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122917930","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}

However, the measurement of the amount delivered can only be done in one way: isolate the components first; then meter, weigh or measure the volume for each individual component. This measuring procedure often stalls the production rate. This work implements a noninvasive, real time monitoring system to measure the flow concentration and velocity distributions of a two-phase (liquid-gas) flow. The system uses the combination of a specially designed twin-plane segmented Electrical Capacitance Tomography (ECT) sensor with 16 portable electrodes and the cross-correlation method as the velocity measurement technique. The measured values or data from the ECT sensor will be manipulated to reconstruct the cross sectional image of the pipeline by computer programming. These images are then cross-correlated to obtain the velocity profile of the multiphase flow. The visualization results deliver information regarding the flow regime, superficial velocity and concentration distribution in two-phase flow rate measurement system. The information obtained is able to improve: the process equipment's design, verification of existing computational modeling and simulation techniques. This technique has the possibility to promote an excellent opportunity to build methods for measuring the velocity field in multiphase flow by using noninvasive technique and cross-correlating.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"642 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133986601","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}

This paper proposes two robust algorithms based on maximum a-posteriori probability (MAP) and minimum mean-squared error (MMSE) estimators to recover wideband block-sparse spectrum and then detect the spectrum holes in compressive spectrum sensing (CSS). In each iteration of the referred Block-sparse Orthogonal Matching Pursuit based on iterative MAP (BOMP-IMAP) algorithm, one index of block is firstly identified to expand the estimated support. And then, wideband block-sparse spectrum can be recovered through approximating the MAP estimator. Finally, the residual is updated and put into next iteration. In order to approximate the MMSE estimator, the Random BOMP-IMAP (RandBOMP-IMAP) algorithm utilizes a randomized block identification of BOMP-IMAP algorithm to generate multiple solutions, which is followed by the fusion of them to obtain the final approximation. Numerical simulation results concerning probability of detection and detection time under certain noise level or measurement number validate the superiority of the proposed algorithms.","PeriodicalId":424006,"journal":{"name":"2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125071116","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}
