Efficient Evaluation of Reliability-Oriented Sensitivity Indices [PDF]
Journal of Scientific Computing, 2019 The role of simulation keeps increasing for the reliability analysis of complex systems. Most of the time, these analyses can be reduced to estimating the probability of occurrence of an undesirable event, also called failure probability, using a stochastic model of the system.

Reliable Anti-Cancer Drug Sensitivity Prediction and Prioritization
Scientific Reports, 2023 Abstract The application of machine learning (ML) to solve real-world problems does not only bear great potential but also high risk. One fundamental challenge in risk mitigation is to ensure the reliability of the ML predictions, i.e., the model error should be minimized, and the prediction uncertainty should be estimated.

Reliability sensitivity analysis based on multi-hyperplane combination method
Defence Technology, 2014 For a nonlinear limit state function, the first-order reliability method (FORM) may cause large errors in the computation of not only the reliability index or failure probability but also the reliability sensitivity.

Research on Structural reliability and reliability sensitivity of EMU pantograph
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Due to the uncertainty of the contact state between the pantograph and the power grid when the EMU is running at high speed, as well as the influence of road conditions and environment, the external load applied to the pantograph and the material properties of the pantograph have certain randomness, thus affecting the current ...

Global sensitivity analysis in stability problems of steel frame structures
Journal of Civil Engineering and Management, 2016 Slender steel frame structures are characterised by a number of imperfections which may reduce their load carrying capacity drastically. This article studies the effects of these imperfections on the load carrying capacity of a single storey steel plane ...
