Reliability models of systems with common cause failure are developed through system-level load-strength interference analysis. Based on the statistic meaning of random load action and the failure mechanism of systems under repeated random load, the effect of multiple action of random load on reliability is studied. The probability cumulative distribution function and the probability density fu...

We report a rare case of common atrium and acute decompensated heart failure most likely precipitated by acute bacterial pericarditis leading to premature death, in a 25-year-old male footballer. The silent course of the disease for decades as well as the diagnostic and management pitfalls of this case illustrates the importance of early detection by echocardiography and urgent appropriate trea...

to delineate the incidence , epidemiology, etiology, and prognosis of acute renal failure (arf) and to compaed the findings with international data, we prospectively studied 2360 patients, admitted at shariati hospital during a four months period ending on jan, 6, 1996. one hundred and twenty-four (5.1%) patients meeting arf crieteria were encountered. the most common cause of arf was prerenal ...

-This paper provides a comprehensive survey on the state-of-the-art condition monitoring and fault diagnostic technologies for wind turbines. The Part I of this survey briefly reviews the existing literature surveys on the subject, discusses the common failure modes in the major wind turbine components and subsystems, briefly reviews the condition monitoring and fault diagnostic techniques for ...

In this paper, we identify an error in the proof of Theorem 1 in the paper Xia, L., Zhao, Q., and Jia, Q.S., “A Structure Property of Optimal Policies for Maintenance Problems with Safety-Critical Components”, IEEE Transactions on Automation Science and Engineering, 2008, 5(3): 519-531. Theorem 1 is the most important contribution of the above paper, which shows the optimality of the so-called ...
