Importance sampling in the evaluation and optimization of buffered failure probability [PDF]

, 2015
Engineering design is a process in which a system’s parameters are selected such that the system meets certain criteria. These criteria vary in nature and may involve such matters as structural strength, implementation cost, architectural considerations,

Development of simple estimation method for the influence of parameter uncertainty of probability distributions against evaluation result of probabilistic fracture mechanics

Nihon Kikai Gakkai ronbunshu, 2016
Probabilistic fracture mechanics (PFM) analysis is an evaluation method for the structural integrity of components containing a crack, with considering the random variability of the input physical parameters, such as crack growth rate.

Failure Probability Estimation Using Asymptotic Sampling and Its Dependence upon the Selected Sampling Scheme

Transactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2017
The article examines the use of Asymptotic Sampling (AS) for the estimation of failure probability. The AS algorithm requires samples of multidimensional Gaussian random vectors, which may be obtained by many alternative means that influence the ...

A CALCULATION METHOD OF EQUIVALENT FAILURE RATE OF VALVE CONSIDERING THE INFLUENCE OF NON-CRITICAL STATE

Jixie qiangdu, 2020
The present method of calculating equivalent failure probability did not take into account the influence of noncritical state of components on the reliability of valve system,which leads to insufficient reliability evaluation results.

Failure Probability Under Parameter Uncertainty [PDF]

, 2010
In many problems of risk analysis, failure is equivalent to the event of a random risk factor exceeding a given threshold. Failure probabilities can be controlled if a decisionmaker is able to set the threshold at an appropriate level.

Analytical method of incorporating failure probability to predict the fatigue life of ultra-high-performance concrete (UHPC)

Frontiers in Built Environment
This study predicted the fatigue life (N) of UHPC incorporated with different volume fractions (Vf = 0.0%, 0.5%, 1.0%, 1.5% and 2.0%) of steel fiber under flexural cyclic loading at various stress levels (S).

Point process approach to modeling and analysis of general cascading failure models

, 2017
A cascading failure is a failure in a system of interconnected parts in which the failure of a part can trigger the failure of successive parts. Although an initial and introductory approach for probabilistic modeling and analysis of the cascading ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...
