Reliability Engineering & System Safety, 2023 This paper addresses the challenge of performing importance sampling in high-dimensional space (several hundred inputs) in order to estimate the failure probability of a physical system subject to randomness. It is assumed that the failure domain defined

St. Petersburg Paradox and Failure Probability [PDF]
Physical Review Letters, 2020 The St. Petersburg paradox provides a simple paradigm for systems that show sensitivity to rare events. Here, we demonstrate a physical realization of this paradox using tensile fracture, experimentally verifying for six decades of spatial and temporal data and two different materials that the fracture force depends logarithmically on the length of the

Depression mediates physical activity readiness and physical activity in patients with heart failure
ESC Heart Failure, 2021 Aims Although physical activity (PA) and exercise are essential for patients with heart failure (HF), adherence to the recommended guidelines is low. Not much is known about the mediating effect of HF patients' mental state with their readiness for PA ...

Acta Polytechnica CTU Proceedings, 2022 The performance of concrete tunnel structures during and after fire is not well understood. This is an obstacle to the adoption of risk-based approaches for fire safety design of tunnel structures.

Failure Probability Under Parameter Uncertainty [PDF]
Risk Analysis, 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. This abstract situation applies, for example, to environmental risks with infrastructure controls; to supply chain ...

Improved active learning probabilistic approach for the computation of failure probability
, 2021 This paper presents a cost-effective probabilistic approach to be used in engineering applications. The proposed approach consists of an improved Kriging-based method aiming at reducing to a minimum the number of evaluations of the true performance ...

The Cross-Dike Failure Probability by Wave Overtopping over Grass-Covered and Damaged Dikes
Water, 2021 A probabilistic framework is developed to calculate the cross-dike failure probability by overtopping waves on grass-covered dikes. The cross-dike failure probability of dike profiles including transitions and damages can be computed to find the most ...
