Reliability Confidence Indicator

2020 Annual Reliability and Maintainability Symposium (RAMS), 2020
The capability of a product to meet the expected reliability targets is extremely difficult to measure during the product development phases. Unlike weight, power consumption, or any other physical or performance parameters, there are no standard defined means to measure the status of the reliability during the various phases of the product development.

Fuzzy Indices of Document Reliability

2007
This paper presents a first step toward the formalization of the concept of document reliability in the context of Information Retrieval (and Information Filtering). Our proposal is based on the hypothesis that the evaluation of the relevance of a document can also depend on the concept of reliability of a document.

Process capability indices and product reliability

Microelectronics Reliability, 2001
Abstract This paper discusses process capability indices— C p and C p k , their underlying assumptions, and the relationships between process capability indices and product reliability. An actual case is presented to demonstrate this relationship.

Principles of Defining Reliable Change Indices

Journal of Clinical and Experimental Neuropsychology, 2000
In this article, several salient measures for determining reliable change are scrutinized. The classic null hypothesis method is compared with more recent procedures based on interval estimation of the true change, including Kelley's formula. The latter category of methods are shown to entail serious drawbacks. If Kelley's formula is expanded to a null

Evaluation of reliability and reproducibility of dental indices

Journal of Clinical Periodontology, 1993
Abstract Evaluation of periodontal therapy involves the use of several oral indices to describe the health status of hard and soft tissues. It was the objective of the present study to evaluate the reliability and reproducibility of some of these indices.

Indices, Institutions and Economic Growth: In Search of Reliable Indicators (Recount) [PDF]

SSRN Electronic Journal, 2014
The ratings of economic and political institutions are well-known and widely used in the Social Science literature. These ratings are heavily relied on Experts' evaluations with subjective ordinal ranking (i.g., from -10 to 10 points). Such evaluations can be occasionally driven by ideological considerations.

Are theophylline “levels” a reliable indicator of compliance?

Journal of Allergy and Clinical Immunology, 1989
Clinicians frequently rely on serum theophylline concentrations (STCs) as an indicator of compliance for asthma medications. Most patients with good compliance do not have excessive fluctuations during routine STC monitoring. However, our experience is that in certain patients, persistently low or erratic STCs may be a sign of abnormal theophylline ...

Quadric reliability indices

Reliability Engineering, 1987
Limit state models based on multi-dimensional rotational paraboloids and hyperboloids are described, and approximate closed form solutions obtained for the associated failure probability and corresponding reliability index. The solutions presented depend only on the number of variables, minimum distance of the limit state surface from the origin and ...

Reliability with wear indicator

Filtration + Separation, 2018
When a filter belt needed changing at a sewage treatment plant, it was given a GKD belt press with a wear indicator. This belt offered better performance than its predecessors and delivered by significantly increasing the plant's reliability and meeting high expectations.

Validity and reliability of self-monitoring indices

Brain Injury, 2008
This research concerns the measurement of self-monitoring in people who were diagnosed with traumatic brain injury (TBI), learning disability (LD) and emotional disorder (ED). Two measures of self-monitoring were evaluated: (1) the correlation between participants' self-predicted and observed standardized sub-test scores (R) on 17 WAIS-III 1 sub-tests ...
