Current mainstream techniques in structural reliability analysis use an iterative first-order reliability method that performs an indirect uncertainty evaluation by finding the most probable failure point. However, such an approach could lead to high computational time due to slower convergence, and in some cases, poor convergence that leads to unreliable results. In order to address the shortcomings, this paper applies a new high-order moment propagation technique (that was initially developed for the measurement uncertainty analysis) to structural reliability analysis problems aiming to obtain results that are simultaneously accurate and computational efficient. The proposed approach was implemented on a three-story elastic frame structure, and the presented results prove that the application of a technique from the field of measurement uncertainly can indeed be applied to complex problems in the structural reliability analysis in order to reduce the trade-off between accuracy and computational efficiency.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114640312","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}

Study of thermal loads in forming coil during repeated EMF process is necessary before its industrialization, and is instructive to coil design. In this paper, several groups of repeated discharges experiments with two different coils were carried out. Fluorescence fiber measurement was applied in the experiments to acquire the coil temperature, and it was proved to be a suitable and promising method in measuring the temperature of electrical equipment. A finite element simulation model of plate forming coil has been established based on COMSOL Multiphysics. The experiment results showed good accordance with the simulation. The results proved that the coil reached an equilibrium temperature after a short period of time. By analyzing the equilibrium temperature, the effect of the crowbar circuit was verified, and a simple method of estimating coil temperature rise in repeated EMF processes based on discharge energy was proposed.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116220595","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 Phasor Measurement Units (PMUs) meet these requirements by providing the measurements obtained from the voltage and current signals with an absolute time reference referred to the Coordinated Universal Time, typically provided by Global Positioning System receivers. For a practical usability of the data provided by PMUs, the measurement results should be accompanied by a suitable information about their quality, so that the system operator can definitely rely on them. In this paper, the behavior of commercial PMUs under loss and restoration of the GPS signal is analyzed and discussed by means of experimental tests. The performance of the devices in terms of Total Vector Error are correlated with the time quality information sent by PMUs, according to the standard IEEE C37.118.2, together with the measurements during the transients corresponding to synchronization issues. The reported analysis allows putting in evidence important considerations about measurement accuracy and trustworthiness during synchronization issues and, in this perspective, highlights what are good practices in PMU implementation.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122110211","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 advantage of an MIP receptor is that it presents a better stability out of the native environment, very good reproducibility, low cost and, furthermore, it can be directly deposited on the gold sensing layer, without modifying the metal surface by functionalizing procedures. PFOA (Perfluorooctanoate) and PFOS (Perfluorooctanesulfonate) are the most extensively investigated PFAs because human exposition can occur through different pathways, and the dietary intake seems to be their main route of exposure. The experimental results have shown that the developed optical chemical sensor makes it possible to detect the above compounds. Sensor's response is exactly the same for PFOA, PFOS or PFAs contaminants. The limit of detection (LOD) of the developed chemical sensor was about 0.2 ppb, a value that is lower than the maximum residue limit fixed by the European Union regulations. This optical chemical sensor could be used for remote sensing, taking advantage of the capability of the optical fiber.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"283 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122228395","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}
