Although comprehensive knowledge of cyber-physical systems (CPS) is becoming a must
for researchers, practitioners, system designers, policy makers, system managers, and …

The initialization of equation-based differential-algebraic system models, and more in
general the solution of many engineering and scientific problems, require the solution of …

Airframers realize that global optimization of the entire aircraft is the only remaining way to
achieve substantial improvements in the total aircraft package. Therefore, this thesis …

This paper is concerned with the tearing method according to François Cellier. Tearing is
used to reduce the dimension of algebraic loops, which inevitably arise in the modelling of …

Modelica is a multi-domain object-oriented modeling language designed for time-dependent
systems. The timedependent part is usually described with “ordinary differential equations” …

Um den Petri-Netz-Simulator zu ermöglichen, wurde das OpenModelica-Backend, der
mathematische Transformationsprozess, neu strukturiert und implementiert. Insbesondere …

A technique for the adaptive order reduction of large scale non-linear differential algebraic
equations (DAEs) is outlined in this report. The order reduction is adaptive, requiring no …

This article presents the results of research into the field of dynamic simulation of
mechanical and robotic systems. The main goal of the whole project is to achieve an efficient …

State-of-the-art Modelica implementations may fail in various ways when tearing is turned
on: Completely incorrect results are returned without a warning, or the software fails with an …

As an opportunity to show the evolution of the state of the art in modular physical modelling,
the model of a gripper for space robotics applications, already developed in the MOSES …
