Human factors are among the main elements affecting the reliability of nondestructive examinations (NDE). In a man-machine system, human reliability is affected by many factors (performance shaping factors) whose influence on reliability cannot be easily expressed quantitatively. This paper identifies and ranks 59 perform-ance shaping factors by using a fuzzy reasoning method and proposes a pro...

Increasing demand for automatic large area surveillance has made methods estimating direction of arrival (DOA), especially acoustic methods, an interesting topic. In these systems false alarms and faults are a disturbing factor. This paper presents a reliability criterion and a new method to diminish these errors. In very low signal-to-noise ratio conditions there are seldom any means to improv...

Online knowledge repositories typically rely on their users or dedicated editors to evaluate the reliability of their content. These evaluations can be viewed as noisy measurements of both information reliability and information source trustworthiness. Can we leverage these noisy evaluations, often biased, to distill a robust, unbiased and interpretable measure of both notions? In this paper, w...

In many practical situations, one may be interested in knowing the extent to which the system will survive an interval of duration after it has been run for a long time. In such situation, the limiting interval reliability may be used as an appropriate measure for system effectiveness. Also, since it is difficult to obtain closed form expressions for the interval reliability, except for few sim...

In this paper, we consider Harary graphs as candidate solutions for the design of a physical network topology that achieves a high level of reliability using unreliable network elements. Our network model, which is motivated by the use of all-optical networks for high-reliability applications, is one in which nodes are invulnerable and links are subject to failure in a statistically independent...

purpose: the sport anxiety scale-2 (sas-2) is a tool by which we can measure the level of trait competitive anxiety. the original form included 15 questions and three subscales included: somatic, worry, and concentration distraction. the aim of this study was to examine of validity and reliability of persian version of sport anxiety scale-2 in children and teenager athletes. methodology: 358 qu...

the competitive state anxiety inventory (csai-2) is the most widely used instrument to measure competitive anxiety in the literature. the aim of this study was to examine the factorial validity and reliability of persian version of competitive state anxiety inventory-2 regarding intensity, direction, and frequency dimensions. the original form included 27 questions and 3 subscales including som...

This study is a reliability generalization meta-analysis that reviews 5 of the most frequently used continuous measures of adult attachment security: the Adult Attachment Scale, Revised Adult Attachment Scale, Adult Attachment Questionnaire, Experiences in Close Relationships, and Experiences in Close Relationships-Revised. A total of 313,462 individuals from 564 studies provided 1,629 internal...

Uncertain variable is defined as a measurable function from an uncertainty space to the set of real numbers for describing subjective uncertain phenomena, which is employed to characterize the element, component and system lifetimes in this paper. Within the framework of uncertainty theory, reliability measure and percentile lifetime are defined to measure the system reliability in this paper. ...

We present a multimodal open-set speaker identification system that integrates information coming from audio, face and lip motion modalities. For fusion of multiple modalities, the so called product rule with a novel adaptive reliability based weighting structure is employed. The proposed adaptive product rule is more robust in the presence of unreliable modalities, provided that the employed r...
