However, some inherent properties of SSDs result in different behavior for SSDs in comparison with Hard Disk Drives (HDDs). As an inherent property, the Bit Error Rate (BER) of SSDs increases, when the number of Program/Erase (P/E) cycles arises. This increment leads to two effects in an array of SSDs during its operation: (1) different BER on different SSDs of the system (SSD-variant BER), and (2) different BER in different time moments (time-variant BER). With respect to these two effects, the reliability evaluation of SSD-based RAIDs would be different from HDD-based RAlDs. This paper introduces a simulator called SOYA for evaluating the reliability of RAH) systems regarding different BER of SSDs. Both time-variant BER and SSD-variant BER have been considered in the evaluation process of this simulator. This simulator provides the ability to compare the reliability of SSD-based RAID systems considering arbitrary parameters in the evaluation such as disk failure rate, disk repair time, RAID-controller failure rate, RAID-controller repair time, and different levels of reliability. SOYA is the first SSD-based reliability simulator for SSD-bases RAID systems which can consider all the above-mentioned parameters together in its reliability evaluation.","PeriodicalId":164248,"journal":{"name":"2016 International Conference on System Reliability and Science (ICSRS)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122914697","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}

In a nuclear power plant, typically, electromagnetic relays are used to communicate shutdown signals between various parts of safety instrumentation. Relay contact welding is a failure mode of concern. An online technique to diagnose this failure mode has already been published by this author and her team. The aim of the paper is to show that the implementation of this technique is practical using a Relay Output Card (ROC) and to highlight reliability improvement. Printed circuit board (PCB) schematic of ROC is described. Markov model is established to determine unsafe state probability of the system. Reliability analysis proves that the diagnostic circuitry in ROC significantly reduces unsafe state probability. It is also demonstrated that failures in diagnostic circuitry have very less significance on the unsafe state (steady state) probability of the system. Sensitivity analysis has been carried out by varying the test interval and proof test interval.","PeriodicalId":164248,"journal":{"name":"2016 International Conference on System Reliability and Science (ICSRS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131560813","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}

These efforts are manifested by the vibration of the whole structure of the machine. For the collection of data necessary to analyze the origin of these efforts are often used vibration sensors, whose function is to transform mechanical energy into a proportionate and measurable electrical signal. In the present work, we limited our study to the search for the best position of the sensor and the measurement point of taking a significant vibration. For this, we considered nine measurements points regularly distributed over half the circumference (180°) of the driving motor of a motor-fan group mounted on flexible substrates, so measurement points that have a pitch equal to 22,5°. In this installation, we have identified three zones; A, B, and C there is seen that amortization is only provided and limited by zone B. The measurements made, have led us to confirm that the measurements points to this type group of motor-fan, will be performed on the horizontal plane and loins of the amortized zone B. In addition, we have taken for this analysis both measurement, one without unbalance and another with the presence of unbalance. In the end, the FFT calculation under Matlab software of the time signal data delevred by the sensor to an oscilloscope is used.","PeriodicalId":164248,"journal":{"name":"2016 International Conference on System Reliability and Science (ICSRS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131224853","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}

In this paper, classification of normal, wheeze, rhonchi, line and coarse crackles using breath sound signal recording is performed using signal processing and machine learning tools. Breath sounds were filtered from noise and segmented into breath cycles followed by feature extraction. AR Coefficients and Mel Frequency Cepstral Coefficients (MFCC) features were extracted from breath sound cycles. The extracted features are then classified using Support Vector Machine (SVM) classifier. A mean classification accuracy of 88.72% and 89.68% was reported for the features AR coefficients and MFCC features respectively. The individual classification accuracy for healthy (control subjects), wheeze, rhonchi, fine and coarse crackles are 93.75%, 87.50%, 91.66%, 87.50% and 91.66% respectively for the MFCC features. Similarly, the individual classification accuracy for healthy control, wheeze, rhonchi, fine and coarse crackles are 93.75%, 87.50%, 87.50%, 87.50% and 83.33% respectively for the AR coefficient features. The experimental result shows that the proposed method from an overall point of view can be considered as a reliable system to be used as a Computerized Decision Support System (CDSS).","PeriodicalId":164248,"journal":{"name":"2016 International Conference on System Reliability and Science (ICSRS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124870216","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}
