Sensitivity analysis of random linear dynamical systems using quadratic outputs
Roland Pulch, Akil Narayan
In uncertainty quantification, a stochastic modelling is often applied, where parameters are substituted by random variables. We investigate linear dynamical systems of ordinary di…
Time and Frequency Domain Methods for Basis Selection in Random Linear Dynamical Systems
John D. Jakeman, Roland Pulch
Polynomial chaos methods have been extensively used to analyze systems in uncertainty quantification. Furthermore, several approaches exist to determine a low-dimensional approxima…
Sparse Representations for Uncertainty Quantification of a Coupled Field-Circuit Problem
Roland Pulch, Sebastian Schöps
We consider a model of an electric circuit, where differential algebraic equations for a circuit part are coupled to partial differential equations for an electromagnetic field par…
Frequency domain integrals for stability preservation in Galerkin-type projection-based model order reduction
Roland Pulch
We investigate linear dynamical systems consisting of ordinary differential equations with high dimensionality. Model order reduction yields alternative systems of much lower dimen…
