Beyond Order: Perspectives on Leveraging Machine Learning for Disordered Materials
Advanced Engineering Materials, EarlyView.This article explores how machine learning (ML) revolutionizes the study and design of disordered materials by uncovering hidden patterns, predicting properties, and optimizing multiscale structures. It highlights key advancements, including generative models, graph neural networks, and hybrid ML‐physics methods, addressing challenges like data ...

Identification of Failure Rates
Calcutta Statistical Association Bulletin, 2003In this paper, we give an identity based on conditional mean to determine the failure rate of a distribution. Some well-known characterizations are deduced as special cases. We also present various applications of the identity. By extending this to the bivariate case, we obtain a class of distributions with a specified form of failure rate. Finally we

Relationship Between System Failure Rate and Component Failure Rates
Technometrics, 1963A simple sufficient condition is given for a system to have an increasing failure rate when the identical components comprising it have an increasing failure rate. Systems which function if and only if at least k of the n components function (“k out of n” systems) satisfy this condition.

Failure rate — a unified approach
Journal of Applied Probability, 1976Aging, of biological and mechanical systems, is well described as ‘deterioration of the power to withstand destruction.’ The failure-rate concept is the mathematical way of describing aging. Failure rates have been defined for discrete and continuous time and used extensively, particularly in actuarial science and reliability.

On Mixture Failure Rates Ordering [PDF]
Communications in Statistics - Theory and Methods, 2006 Mixtures of increasing failure rate distributions (IFR) can decrease at least in some intervals of time. Usually, this property can be observed asymptotically as t → ∞. This is due to the fact that the mixture failure rate is “bent down” compared with the corresponding unconditional expectation of the baseline failure rate, which was proved previously ...

The rate of occurrence of failures
Journal of Applied Probability, 1997In this article, we assume that the state of a system forms a continuous-time Markov chain or a higher-dimensional Markov process after introducing some supplementary variables. A formula for evaluating the rate of occurrence of failures for the system is derived.

Gasunie buys and sells gas. This paper is about calculating the failure rate of the gas transport system of Gasunie in the Netherlands. The pipes in the network are connected at certain stations which may operate at degraded levels due to technical problems.

In our everyday life, we are frequently much more interested in the reliability of used goods than new ones. When someone buys a clock, the consumer has a warranty from the store ensuring that he can replace the clock with a new one or have it repaired if the clock fails within a certain period of time.

On the behavior of the failure rate and reversed failure rate in engineering systems
Journal of Applied Probability, 2020AbstractIn this paper the behaviour of the failure rate and reversed failure rate of an n-component coherent system is studied, where it is assumed that the lifetimes of the components are independent and have a common cumulative distribution function F.
