These data serve as the regularization for EIT algorithm. The measurements were carried out at 125 kHz on biological swine tissues. Plunge electrodes in four-terminal configuration and a computer-automated measurement system were used to acquire admitivity data. Measurements were taken on myocardial muscle (three different positions on epicardial surface), pectoral and intercostals muscles, adipose tissue, costal cartilage and lungs (cranial lobe, middle lobe and caudal lobe). Admitivity temporal variations synchronized with perfusion and ventilation rates were observed. Increased PEEP lead to increased time averaged admitivity in lung tissues. The collected data were used to increased image resolution on EIT.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130149120","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}

It adopts scan conversion approaches of lines and circles developed in raster graphics in SAFT so as to avoid the iterative computations in the traditional ultrasonic SAFT with ray tracing. Since this method is suitable for parallel implementation, a GPU-accelerated ultrasonic motion trajectory algorithm is also implemented with CUDA to achieve real-time ultrasonic imaging. Experiments show that the presented motion trajectory method is the most efficient approach for ultrasonic imaging of multi-layered objects among the existing reconstruction techniques, such as the phase shift migration and the traditional method that combines synthetic aperture focusing technique (SAFT) with ray tracing techniques. This new method speeds up the ultrasonic imaging procedure of multi-layer objects by two orders of magnitude with better effects than the traditional method.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128913965","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 aim is to detect ground motion near critical infrastructure during excavation is the vicinity. The required computation corresponds to an inverse boundary value problem with uncertain boundary values. The solution is formulated as a covariance weighted Hermite approximation problem. Additionally, a method of taking advantage of the properties of the over-constrained system to identify a defective sensor is presented. The correct functionality of the proposed method and its performance in terms of uncertainty is demonstrated with a Monte Carlo simulation.

The analysis of the propagation of error and uncertainty of load profiles in state estimation must be investigated, as state estimation in distribution is being experimentally deployed, and the use of any available source of data is under consideration. The findings should provide hints on the accuracy to be expected and on corrections to be applied to update classical pseudo-measurements.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124051576","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}

Whereas the major purpose of WirelessHART is the read-out of sensors with moderate real-time requirements, an increasing demand for integration of actuator applications can be observed. Therefore, it must be verified that the WirelessHART protocol gives sufficient support to real-time industry requirements. As a result, the delay of especially burst and command messages from actuator and sensor nodes to the gateway and vice versa must be analyzed. In this paper, we implemented a WirelessHART network scenario in WirelessHART simulator in NS-2 , simulated and analyzed its time characteristics under ideal and noisy conditions. We evaluated the performance of the implementation in order to verify whether the requirements of industrial process and control can be met. This implementation offers an early alternative to expensive test beds for WirelessHART in real-time actuator applications.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124096212","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}

But these methods had the defects such as needing standard carrier gas, regularly instrument calibration, low security, long analysis time and so on. For these reasons, an innovative method of using Fourier transform infrared (FTIR) instrument to detecting and analysis the transformer oil dissolved gas was proposed in this paper. This method has the features, such as maintenance free, no carrier gas in site, analysis time shortly (time constant below one second is possible). The detecting and analysis system was consisted by the oil sample continuous automatic collection device, oil dissolved gases separation equipment, gases analytical instruments (FTIR), data acquisition and processing module. The situation of the transformer in-site operation was simulated and a complete experimental system was set up in the laboratory. When we used the FTIR to analyze the gases on site for a long time and continuously, some key technologies (spectral baseline drift and distortion, dimension reduction and so on) needed to resolve. For the spectral baseline drift and distortion problem, the spectral baseline correction by piecewise dividing (SBCPD) baseline correction algorithm was used to preprocess the spectral data. For the problem of high-dimensional data characteristic variables selection in the spectral analysis, Tikhonov regularization algorithm was used to select spectral features variable. After the above step, the dimensions of the original spectrum was reduced from 10165 to 3~7, the computing workload was greatly reduced and the accuracy of the calculation results was improved. Finally, the sparse partial least squares algorithm was adopted to establish the quantitative analysis model of transformer dissolved gas analysis on-line monitoring system, and 7 kinds of mixed gases were analyzed. The results showed that the sparse partial least squares algorithm was superior to the traditional partial least squares algorithm. The feasibility of Fourier transform infrared spectroscopy for oil dissolved gas multi-component on-line detection and analysis system was preliminary verified by the simulation and experiment system in the laboratory.","PeriodicalId":331484,"journal":{"name":"2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126721534","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}
