This paper presents an applicable health monitoring method for Li-ion batteries based on profust reliability theory. The word “profust” derives from “probability” and “fuzzy-state”, which means that the profust reliability theory is a kind of fuzzy reliability theory based on probability assumption and fuzzy-state assumption. It defines a concept of transition from fuzzy success to fuzzy failur...
BACKGROUND A reliable and valid global staging scale has been lacking within dementia care. OBJECTIVE To develop an easy-to-use multi-dimensional clinical staging schedule for dementia. METHODS The schedule was developed through: i) Two series of focus groups (40 and 48 participants, respectively) in Denmark, France, Germany, Netherlands, Spain, Switzerland, and UK with a multi-disciplinary...
BACKGROUND Systematic reviews of the relationship between non-manipulated factors (e.g. low empathy) and offending are becoming more common, and it is important to consider the methodological quality of studies included in such reviews. AIMS To assess aspects of the reliability and validity of the Cambridge Quality Checklists, a set of three measures for examining the methodological quality o...
This paper introduces the process for, and the result of, the selection of performance influencing factors (PIFs) for the use in human reliability analysis (HRA) of emergency tasks in nuclear power plants. The approach taken in this study largely consists of three steps. First, a full-set PIF system is constructed from the collection and review of existing PIF taxonomies. Secondly, PIF candidat...
PURPOSE To evaluate inter- and intra-rater reliability for the interpretation of MTI Photoscreener photographs taken in a population of Native American preschool children with a high prevalence of astigmatism. METHODS Photographs of 369 children were rated by 11 nonexpert and 3 expert raters. Photographs for each child were scored as pass, refer, or retake. Nonexpert raters scored photos on t...
It is very important to select critical operations in software reliability testing and software safety testing. In this paper, a framework for selecting critical operations based on Analytic Hierarchy Process (AHP) is proposed. The hierarchies of goals, criteria and alternative programs are introduced separately. A preliminary application is practiced to show the method’s application process an...
Indexes of interrater reliability and agreement are reviewed and suggestions are made regarding their use in counseling psychology research. The distinction between agreement and reliability is clarified and the relationships between these indexes and the level of measurement and type of replication are discussed. Indexes of interrater reliability appropriate for use with ordinal and interval s...
The dot-probe task is often considered a gold standard in the field for investigating attentional bias to threat. However, serious issues with the task have been raised. Specifically, a number of studies have demonstrated that the traditional reaction time (RT) measure of attentional bias to threat in the dot-probe task has poor internal reliability and poor test-retest reliability. In addition...
This paper addresses the reliability analysis for a real-world apparel manufacturing system by using fuzzy mathematics. The studied apparel manufacturing system is a precise handicraft profession which involves a great amount of labor-intensive processes. To consider human performance, the apparel manufacturing system is constructed as a fuzzy multistate network, termed apparel manufacturing ne...
