Abstract. The feed water system is one of the most important system for nuclear power plant. Based on an analysis for the working principles of the AP1000 plant main feed water system, a novel fault Petri net model and fault diagnosis method are proposed. The main feed water flow low alarm is a serious fault for the feed water system, Petri net theory is adopted to establish the fault model for this fault signal. Through the consequence and account for this model, fault reasons and reasons probability for the main feed water flow low have been obtained. Application shows that, the fault Petri net has more advantages than the fault tree in qualitative analysis and quantitative calculation. And this method is a new route for the nuclear plant systems’ fault diagnosis.
IntroductionKnee osteoarthritis (KOA) is a frequent degenerative condition. Patients with KOA have employed mind-body therapies frequently, and their efficacy has been established. The main purpose of our study is to compare the effects of different mind-body therapies on patients with KOA.Material and methodsOnly randomized controlled trials (RCTs) were gathered through searches in the Cochrane Library, PubMed, EBSCO, Web of Science, Medline, and Embase to investigate the effects of various mind-body therapies on effect in KOA patients. The Cochrane bias risk assessment tool was used to assess the methodological quality of the included studies, and the data analysis program was then used to analyze the data in accordance.ResultsThe study used an overall sample size of 859 from a total of 17 RCTs. In addition, a total of 13 different mind-body therapies were included in our study. According to the network meta-findings, analysis's patients' scores on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) can be significantly improved by Baduanjin (SUCRA:98.3%), the Time Up and Go (TUG) Test can be significantly decreased by balance training (SUCRA:99.4%), the 36-Item Short Form Health Survey questionnaire's mental health component can be significantly improved by MBSR (SUCRA:87.9%), and balance training can significantly improve patients’ physical health component of SF-36 (SUCRA:90.3%).ConclusionsAccording to the Network's Ranking Plot, Bajuanjin or Balance Training and MBSR can offer patients with KOA higher benefits for motor function or quality of life than other mind-body therapies. The medical staff can choose different mind-body therapies according to the patient's actual condition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
