Predictive Sequential Life Testing

Biometrika, 1978
Sequential tests that are based on some unobservable parameter have been well investigated using both classical and Bayesian approaches; see, for example, Wald (1947) and Barnett (1972). In this paper we use the Bayesian predictive density function to constuct a sequential test that is based on some statistic of a future sample, and investigate the ...

Accelerated Life Test and Life Prediction of an Electromechanical Actuator

2019 International Conference on Artificial Intelligence and Advanced Manufacturing (AIAM), 2019
This paper gives an accelerated test method for electromechanical actuator (EMA) and predicts its life based on Wiener process degradation model. According to the historical fault data and the FMECA analysis, we obtain that the key weak links of the electromechanical actuators are the electromagnetic clutch and the tachogenerator.

Predicting the Dimensions of Life Satisfaction

Journal of Gerontology, 1976
Taking multidimensional life satisfaction as the basic premise of this study, a four-equation multiple regression model was constructed for its prediction. The set of regressors included some conventional biographical characteristics, a number of activity variables, and three indicators of retirement experience.

Life Prediction of Seals

1998
Abstract : The Air Force Research Laboratory requires a method for predicting the relative life of O-rings produced by different manufacturers. O-rings manufactured to the same MIL-spec from different manufacturers usually use different material formulations. Differences in formulations can result in different properties as the O-rings age.

Life Cycle Assessment and Service Life Prediction

Journal of Industrial Ecology, 2014
Summary Models of buildings in life cycle assessment (LCA) often use simple descriptions of operational energy, maintenance, and material replacement. The scope of many building LCAs is often limited and uses assumptions such as building lifetimes of 30 to 50 years.

Fatigue and Life Prediction

2005
Abstract This chapter summarizes the various kinds of gear wear and failure and how gear life in service is estimated and discusses the kinds of flaws in material that may lead to premature gear fatigue failure. The topics covered are alignment, gear tooth, surface durability and breakage of gear tooth, life determined by contact stress ...

Predictability in life and in science

Inquiry, 1961
It is a significant coincidence that social science tends to assume a universal human need for predictability, and also uses predictive power as the basic criterion of scientific truth. It is claimed here that man's need for predictability often is crossed by a need for uncertainty and chance.

Prediction of Quality of Life in Patients with Tinnitus

British Journal of Audiology, 2000
According to epidemiological studies of tinnitus prevalence, 0.5-1% of respondents report that tinnitus severely affects their ability to lead a normal life. In the present investigation quality of life and its association with tinnitus-related factors: psychological, psychosomatic and audiological, was studied based on a sample of 122 patients, who ...
