Rolling contact fatigue is a unique mode of that components under cyclic loading experience. In this work, the impact induction hardening residual stresses in rolling lifetime investigated experimentally and numerically using Dang Van multiaxial criterion. Various stress fields from are simulated finite element method mapped into classical mono-contact model. The hardened on component has been ...

This article addresses the various mathematical and statistical properties of Burr type XII distribution (such as quantiles, moments, moment generating function, hazard rate, conditional mean residual lifetime, past deviation about median, stochasic ordering, stress-strength parameter, entropies, Bonferroni Lorenz curves order statistics) are derived. We discuss some exact expressions recurrenc...

In clinical trials of chronic diseases such as acquired immunodeficiency syndrome, cancer, or cardiovascular diseases, the concept of quality-adjusted lifetime (QAL) has received more and more attention. In this paper, we consider the problem of how the covariates affect the mean QAL when the data are subject to right censoring. We allow a very general form for the mean model as a function of c...

In this paper we suggest how to est,imate a mean lifetime in the presence of vague data, especially imprecise number of failures.

In many industrial and medical applications observations are censored either due to inherent limitations or cost/time considerations. For example, with many products their lifetimes are sufficiently long that it is infeasible to test all products until failure even using accelerated testing. As a result, often a limited stress test is performed and only a proportion of the true failure times ar...
