Life Prediction of Notched Components

Journal of Engineering Materials and Technology, 1995
In this study, keyhole and smooth specimens, made from a low alloy pressure vessel steel (ASTM A-533 grade B), were subjected to monoaxial fatigue tests. The results show the influence of the stress concentration factor, Kt, on the number of cycles to failure, Nf.

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.

Shelf-life prediction

1987
The term ‘shelf life’ is generally understood to be the duration of that period, between packing a product and using it, for which the quality of the product remains acceptable to the product user. An attempt to predict this period from data on the product, the pack and the distribution and storage conditions is appropriate where alternative packaging ...

Predicting scientists’ participation in public life

Public Understanding of Science, 2012
This research provides secondary data analysis of two large-scale scientist surveys. These include a 2009 survey of American Association for the Advancement of Science (AAAS) members and a 2006 survey of university scientists by the United Kingdom’s Royal Society.

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.
