Bearings are widely used in rotating machines. Its health status is a significant index to indicate whether machines run continually or not. Detecting the bearing faults timely is very important for the maintenance decision making. In this paper, a new fault diagnosis method based on envelope analysis and Euclidean Distance is developed. Envelope analysis is used to enable the fault frequencies...

Extracting features from original signals is a key procedure for traditional fault diagnosis of induction motors, as it directly influences the performance of fault recognition. However, high quality features need expert knowledge and human intervention. In this paper, a deep learning approach based on deep belief networks (DBN) is developed to learn features from frequency distribution of vibr...

On power system operation status monitoring, operating performance analysis and assessment is to ensure the safe operation of its important components. This paper presents a new type of data mining based on the fault mode analysis and the fast diagnostic reasoning algorithm. Fault appearance to be collected and cleaned up in a fault information dimension table, the relationship rule dimension t...

Previous studies in the United States and internationally suggest that low motorcycle conspicuity, or the inability of the motorcyclist to be seen by other road users, is an important factor associated with the risk of motorcycle crashes. However, there has been limited research on motorcycle conspicuity in the United States in the past two decades, while at the same time, there has been a rene...

In diagnostic testing faults detectable by test vectors are partitioned into groups. This partitioning is such that a fault is distinguishable from faults in all other groups, but is indistinguishable from those in its own group. Diagnostic fault coverage (DC) is defined as the number of fault groups divided by the total number of faults. We present a new diagnostic fault simulation algorithm t...

BACKGROUND Musculoskeletal injuries are a common cause of morbidity after road traffic injury (RTI) in motorizing countries. District hospitals provide front-line orthopedic care in Uganda and other sub-Saharan African nations. Improving care at the district hospital level is an important component of the World Health Organization's strategy for surgical and trauma systems strengthening, but th...
