Anomaly Detection in Offshore Wind Turbine Structures using Hierarchical Bayesian Modelling

no code implementations29 Feb 2024 S. M. Smith, A. J. Hughes, T. A. Dardeno, L. A. Bull, N. Dervilis, K. Worden

Population-based structural health monitoring (PBSHM), aims to share information between members of a population.

Anomaly Detection

On the hierarchical Bayesian modelling of frequency response functions

no code implementations12 Jul 2023 T. A. Dardeno, K. Worden, N. Dervilis, R. S. Mills, L. A. Bull

In this paper, a combined probabilistic FRF model is developed for a small population of nominally-identical helicopter blades, using a hierarchical Bayesian structure, to support information transfer in the context of sparse data.

Hierarchical Bayesian Modelling for Knowledge Transfer Across Engineering Fleets via Multitask Learning

1 code implementation26 Apr 2022 L. A. Bull, D. Di Francesco, M. Dhada, O. Steinert, T. Lindgren, A. K. Parlikad, A. B. Duncan, M. Girolami

Utilising an interpretable hierarchical Bayesian approach and operational fleet data, domain expertise is naturally encoded (and appropriately shared) between different sub-groups, representing (i) use-type, (ii) component, or (iii) operating condition.

Asset Management Multi-Task Learning +1

On risk-based active learning for structural health monitoring

no code implementations12 May 2021 A. J. Hughes, L. A. Bull, P. Gardner, R. J. Barthorpe, N. Dervilis, K. Worden

A primary motivation for the development and implementation of structural health monitoring systems, is the prospect of gaining the ability to make informed decisions regarding the operation and maintenance of structures and infrastructure.
