Journal ArticleDOI
A survey of preventive maintenance models for stochastically deteriorating single-unit systems
TL;DR: This article includes optimization models for repair, replacement, and inspection of systems subject to stochastic deterioration and a classification scheme is used that categorizes recent research into inspection models, minimal repair models, shock models, or miscellaneous replacement models.
Book
Applied Probability and Stochastic Processes
TL;DR: This book presents applied probability and stochastic processes in an elementary but mathematically precise manner, with numerous examples and exercises to illustrate the range of engineering and science applications of the concepts.

TL;DR: In this paper, the authors proposed an approach for regulatory purposes to reach a decision that RTT, developing as a result of CPN exacerbation in rats, has no relevance for human risk assessment.
Journal ArticleDOI
Ethylene oxide cancer risk assessment based on epidemiological data: application of revised regulatory guidelines.
TL;DR: The results of an updated meta-analysis of the findings from 10 unique EO study cohorts from five countries, including nearly 33,000 workers, and over 800 cancers are presented, indicating that EO does not cause increased risk of cancers overall or of brain, stomach or pancreatic cancers.
Journal ArticleDOI
Development of an inhalation unit risk factor for hexavalent chromium
TL;DR: A unit risk factor (URF) was developed for hexavalent chromium (CrVI) based on excess lung cancer mortality in two key epidemiological studies of chromate production workers, which resulted in a final URF for CrVI of 2.3E-03 per μgCrVI/m(3).
