Adaptive Reduced Order Modelling of Discrete-Time Systems with Input-Output Dead Time
Art J. R. Pelling, Ennes Sarradj
While many acoustic systems are well-modelled by linear time-invariant dynamical systems, high-fidelity models often become computationally expensive due the complexity of dynamics…
Snapshot-driven Rational Interpolation of Parametric Systems
Art J. R. Pelling, Karim Cherifi, Ion Victor Gosea +1
Parametric data-driven modeling is relevant for many applications in which the model depends on parameters that can potentially vary in both space and time. In this paper, we prese…
On a lower-order framework for jet noise prediction based on one-dimensional turbulence
Sparsh Sharma, Marten Klein, Heiko Schmidt +1
Noise prediction requires the resolution of relevant acoustic sources on all scales of a turbulent flow. High-resolution direct numerical and large-eddy simulation would be ideal b…
Sparse l1 Regularisation of Matrix Valued Models for Acoustic Source Characterisation
Laurent Hoeltgen, Michael Breuß, Gert Herold +1
We present a strategy for the recovery of a sparse solution of a common problem in acoustic engineering, which is the reconstruction of sound source levels and locations applying m…
