Existing methods based on the Eulerian video magnification (EVM) technique are severely affected by motion (i.e., object movements). The proposed method can consider both scenarios of still and moving subjects to magnify the skin color changes over time. In the proposed method, we employed a wavelet decomposition process along with a denoising layer based on principal component analysis (PCA). PCA smoothed the frames and reduced the noise due to high-frequency fluctuations caused by motion (i.e., unwanted source of color changes in the skin). Finally, the video data was magnified to extract the heart rate information. As a result, subtle changes caused by blood flow were made clearly visible to the naked eye. We compared the heart rate estimation results obtained through our proposed method with the results produced by linear EVM. The experimental results indicate an improvement in the heart rate estimation accuracy in the presence of motion using the proposed method.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"45 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88898827","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}

For complex facilities, suitable condition monitoring systems are individually developed and designed to prevent unexpected plant shutdowns. For the development of a special condition monitoring system for a heavy-load multistage gearbox application, the creation of a realistic demonstrator is suitable. This allows for investigations especially on the rolling bearings installed in the planetary gear and can be used to test the suitability of different sensors. The measurements are conducted under consideration of different parameters and are evaluated by using different analysis methods. Thus, besides the demonstrator, a result of the present paper is an evaluation of various sensors from which recommendations can be derived for the establishment of a condition monitoring system in the examined case. The presented work is addressed to researchers and engineers in the field of condition monitoring of rotating machinery, especially planetary gears and roller bearings.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"4 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80890431","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 static memory cells of SRAM-based configuration memory present a high sensitivity to radiation effects. Due to the increasing interest in using these devices in radiation environments such as aerospace and high energy physics, the evaluation of their reliability through radiation tests is a key role in their validation. Radiation Testing consists in exposing the physical device to radioactive source or radiation beams and represents an accurate solution for evaluating the device sensitivity. However, this implies high costs both in terms of experimental setup and money due to the low availability of the required facilities. Among the possible solutions, neutron generator testing would represent an efficient solution even if challenging from the instrumentation needed for the experimental setup. In this work, we present a test instrumentation and methodology specific for cost-effective short-time neutron generator testing to efficiently evaluate FPGA radiation-induced soft error sensitivity.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"52 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77208900","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}

Indeed, thanks to its robustness and high performances in terms of low power consumption and long transmission range, it has been employed in a wide range of critical application scenarios. In this context, this paper analyses the usability of LoRa as solution for data transmission in icy environments. While the technical feasibility of radio transmission channel in ice has been widely demonstrated, this paper aims at demonstrating the effectiveness of a low cost transmitter developed using off-the-shelf components, when completely immersed in ice. Fields tests were performed by embedding a Low Power Wide Area Network (LoRaWAN) compliant node inside a 10 cm block of dry ice, positioned then in an environmental chamber, at a −10°C temperature. Preliminary tests demonstrate the operation of the transmitter in these operating conditions, while the achieved link margin suggests the usability of this technology even in case of notably thicker layers of ice.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"187 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77264514","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}

Such phenomena like the acoustic dispersion, the frequency dependent attenuation and the resonances are studied in this paper, based on synthesized signals, and their influence on the leak localization accuracy is discussed. Furthermore, a leak localization method combining the cross-correlation technique with temporal and spectral segmentation of the acoustic signals is proposed. This method is applied to measured (stochastic) leak signals from a pipeline in a laboratory setup. Experimental results show that the proposed method can efficiently determine the position of a leak in a pipeline, since the localization error in most cases is below 3%.","PeriodicalId":6772,"journal":{"name":"2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"5 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90415762","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}
