Analytic investigations on the susceptibility of nonlinear analog circuits to substrate noise

Widemann, C.; Stegemann, S.; John, Werner; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2013)

This work deals with the conducted susceptibility of nonlinear analog circuits with respect to substrate noise. The substrate coupling mechanism is modeled by a passive three-terminal network that is obtained by means of ...
A DEIM driven reduced basis method for the diffuse Stokes/Darcy model coupled at parametric phase-field interfaces

Stoter, Stein K.F.; Jessen, Etienne; Niedens, Viktor; Schillinger, Dominik (New York, NY [u.a.] : Springer Science + Business Media B.V., 2022)

In this article, we develop a reduced basis method for efficiently solving the coupled Stokes/Darcy equations with parametric internal geometry. To accommodate possible changes in topology, we define the Stokes and Darcy ...
Efficient modelling of IC conducted emission for power integrity analysis

Kazemzadeh, Reza; Ludwig, Stefan; Radić-Weissenfeld, Ljubica J.; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2009)

In this paper two methodologies to reduce the complexity of IC conducted emission models for Power Integrity analysis in ICs are presented. The methodologies differ concerning the applicability in simulation tools, complexity ...
Efficient passive network description of IC conducted emission models for model reduction

Ludwig, Stefan; Radić-Weissenfeld, Ljubica J.; Mathis, Wolfgang; John, W. (Göttingen : Copernicus GmbH, 2008)

This article adresses the model reduction of IC conducted emission models. A method to efficiently deal with the high number of independent sources in IC conducted emission models, which are a strong limitation for model ...
Model order reduction of linear time invariant systems

Radić-Weissenfeld, Ljubica J.; Ludwig, Stefan; Mathis, Wolfgang; John, W. (Göttingen : Copernicus GmbH, 2008)

This paper addresses issues related to the order reduction of systems with multiple input/output ports. The order reduction is divided up into two steps. The first step is the standard order reduction method based on the ...
Sensitivity-based Model Reduction for In-Process Identification of Industrial Robots Inverse Dynamics

Volkmann, Björn; Kaczor, Daniel; Tantau, Mathias; Schappler, Moritz; Ortmaier, Tobias (Piscataway, NJ, USA : IEEE 2020, 2020)

This paper presents a sensitivity-based approach for optimal model design and identification of the dynamics of a state-of-the-art industrial robot considering process-related restrictions. The possibility of parameter ...
Transformation of passive electrical networks with distributed PWL-sources using a Model Order Reduction

Ludwig, Stefan; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2009)

In modeling of distributed systems with distributed sources large networks with RLC-elements and independent sources arise. This high complexity leads to a high effort in simulations. Therefore model reduction can be used ...
