POMDP inference and robust solution via deep reinforcement learning: An application to railway optimal maintenance
Giacomo Arcieri, Cyprien Hoelzl, Oliver Schwery +3
Partially Observable Markov Decision Processes (POMDPs) can model complex sequential decision-making problems under stochastic and uncertain environments. A main reason hindering t…
A Nonlinear Damped Metamaterial: Wideband Attenuation with Nonlinear Bandgap and Modal Dissipation
Bao Zhao, Henrik R. Thomsen, Xingbo Pu +6
In this paper, we incorporate the effect of nonlinear damping with the concept of locally resonant metamaterials to enable vibration attenuation beyond the conventional bandgap ran…
Assessment of alternative covariance functions for joint input-state estimation via Gaussian Process latent force models in structural dynamics
Silvia Vettori, Emilio Di Lorenzo, Bart Peeters +1
Digital technologies can be used to gather accurate information about the behavior of structural components for improving systems design, as well as for enabling advanced Structura…
A metric for assessing and optimizing data-driven prognostic algorithms for predictive maintenance
Antonios Kamariotis, Konstantinos Tatsis, Eleni Chatzi +2
Prognostic Health Management aims to predict the Remaining Useful Life (RUL) of degrading components/systems utilizing monitoring data. These RUL predictions form the basis for opt…
VpROM: A novel Variational AutoEncoder-boosted Reduced Order Model for the treatment of parametric dependencies in nonlinear systems
Thomas Simpson, Konstantinos Vlachas, Anthony Garland +2
Reduced Order Models (ROMs) are of considerable importance in many areas of engineering in which computational time presents difficulties. Established approaches employ projection-…
Graph Neural Networks for Aerodynamic Flow Reconstruction from Sparse Sensing
Gregory Duthé, Imad Abdallah, Sarah Barber +1
Sensing the fluid flow around an arbitrary geometry entails extrapolating from the physical quantities perceived at its surface in order to reconstruct the features of the surround…
