Gradients and subgradients of buffered failure probability [PDF]
Operations Research Letters, 2021 Gradients and subgradients are central to optimization and sensitivity analysis of buffered failure probabilities. We furnish a characterization of subgradients based on subdifferential calculus in the case of finite probability distributions and, under additional assumptions, also a gradient expression for general distributions.

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.

Bounding Failure Probability with the SIVIA Algorithm [PDF]
Book of Extended Abstracts for the 32nd European Safety and Reliability Conference, 2022 The accuracy of Monte Carlo simulation methods depends on the computational effort invested in reducing the estimator variance. Typically reducing such variance requires invoking Monte Carlo with as many samples as one can afford. When the system is complex and the failure event is rare, it can be challenging to establish the correctness of the failure

Influence of rock mass spatial variability on probability of tunnel roof wedge failure
Rock and Soil Mechanics, 2021 In tunnel design and construction, the stability evaluation of tunnel roof wedge usually adopts traditional deterministic analysis methods, which cannot appropriately reflect the spatial variability of rock mass.
