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…
