This work proposes a methodology based on the Discrete Wavelet Transform to improve in-vitro blood vessels visualization. It also addresses the segmentation of the regions of interest through morphological operations in improved contrast images. Results show that it is possible to visualize the blood vessels even at 700$mu$m below an epidermis phantom.","PeriodicalId":132588,"journal":{"name":"2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116042150","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}

Therefore, a fast quantitative detection of cracks periodically is essential to guarantee the operation safety of the high-speed rail track. Electromagnetic Nondestructive testing (NDT) technique is one of the effective methods for quantitative crack characterization in conduction metals. For high-speed Electromagnetic NDT, because of the relative motion between the rail and detection device, motion induced eddy current (MIEC) is generated in the surface of the rail, which causes the magnetic field distribution inside the rail more complicated due to the dragging effect, and the literatures focus on the investigation on the optimal detection position is rare. Hence, to obtain the optimal detection sensitivity and strength, it is essential to investigate the optimal detection position in electromagnetic NDT for crack characterization in high speed. This paper perform a deep investigation on the optimal detection position in direct current (DC) electromagnetic NDT by numerical simulation, and the influence of detecting position on the detecting signal at different speeds is investigated. The results show that the DC Electromagnetic NDT can be used for quantitative crack depth characterization, and the optimal detection position with strongest detection signal and high sensitivity for crack depth characterization is located near the inner edge of the excitation coil on the opposite side of the direction of the probe motion. According to the findings in this paper, the high-speed DC electromagnetic NDT method can be applied to other moving metal components crack characterization, such as rotating metal components and pipelines.","PeriodicalId":132588,"journal":{"name":"2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121977218","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 presents a novel scanning double-beam laser interferometer (DBLI) to measure the thickness piezoelectric coefficient with a high accuracy. Compared to previous DBLI solutions, we employ a closed-loop phase shift compensation via an electro-optical modulator to stabilize the random phase drift as well as to compensate the harmonic sample-induced phase shift. As a consequence, the setup robustness is enhanced and the measured displacement is no more sensitive to sample reflectivity or source and detector signal gains, which allows to use the DBLI as scanning.","PeriodicalId":132588,"journal":{"name":"2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123582251","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, most of them are based on the prior knowledge that the resonance’s location is known. Since real BTT test usually takes more than ten hours, it’s unrealistic to Figure out every resonance from the measured raw data manually. Furthermore, BTT data analysis suffers from its inherent under-sampled and non-uniform shortcoming. In this paper, we present a simple yet effective method for BTT-based blade health monitoring. The method starts with an automatic resonance recognition, where cross-correlation and Savitzky Golay filter are used to locate the resonance region. Then an adaptively reweighted least-squares periodogram algorithm is designed to identify parameters of the resonant vibration. The effectiveness of the algorithm was tested using both simulation and real test data.","PeriodicalId":132588,"journal":{"name":"2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128528226","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 obtain more quantitative and key information of the flame from images of conductivity and permittivity distributions, a calibration method is necessary for studies on different combustors. In this paper, the ion probe sensor is proposed as a means of verification for electrical tomography in flame monitoring. From the impedance data of the ion probe, the local conductivity and permittivity can be calculated. Both an ion probe sensor and an electrical tomography system were experimented on an alcohol lamp. The ion probe experiment results are that the conductivity increased from $2times 10^{-6}$ to $9times 10^{-6} rm{{S}/{m}}$, while the relative permittivity increased from 1 to 4 in the flame. The ranges of electrical tomography images are that conductivity from 0 to $6times 10^{-6} rm{{S}/{m}}$ and relative permittivity from 1 to 4.5, which are consistent with the data acquired from the ion probe.","PeriodicalId":132588,"journal":{"name":"2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115301334","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 static experiment of the gas-water two-phase medium was carried out. The results showed that the sensor can detect the change of gas-water two-phase medium with 0-10% water volume fraction.
