A model for cascading failures with the probability of failure described as a logistic function. [PDF]
Sci Rep, 2022 AbstractIn most cascading failure models in networks, overloaded nodes are assumed to fail and are removed from the network. However, this is not always the case due to network mitigation measures. Considering the effects of these mitigating measures, we propose a new cascading failure model that describes the probability that an overloaded node fails ...

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

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

Failure probability of regional flood defences
E3S Web of Conferences, 2016 Polders in the Netherlands are protected from flooding by primary and regional flood defence systems. During the last decade, scientific research in flood risk focused on the development of a probabilistic approach to quantify the probability of flooding

The Decoding Failure Probability of MDPC Codes [PDF]
2018 IEEE International Symposium on Information Theory (ISIT), 2018 Moderate Density Parity Check (MDPC) codes are defined here as codes which have a parity-check matrix whose row weight is $O(\sqrt{n})$ where $n$ is the length $n$ of the code. They can be decoded like LDPC codes but they decode much less errors than LDPC codes: the number of errors they can decode in this case is of order $Θ(\sqrt{n})$.

Comparison of the collapse frequency and failure probability of buildings
Acta Polytechnica CTU Proceedings, 2022 In a previous study, the collapse frequencies and associated mortalities of buildings were compiled based on various publications. The investigation showed a considerable scattering of collapse frequencies depending on the countries.
