Uncertainty Propagation of Initial Conditions in Thermal Models
Alexandra Bünger, Roland Herzog, Andreas Naumann +1
The operation of machine tools often demands a highly accurate knowledge of the tool center point's (TCP) position. The displacement of the TCP over time can be inferred from therm…

Adaptive rational Krylov methods for exponential Runge--Kutta integrators
Kai Bergermann, Martin Stoll
We consider the solution of large stiff systems of ordinary differential equations with explicit exponential Runge--Kutta integrators. These problems arise from semi-discretized se…
