Article accepted

Our contribution "Mixed-Integer Real-time Control of a Building Energy Supply System" (A. Burda, D. Bitner, F. Bestehorn, C. Kirches, M. Grotjahn) has been accepted for publication in IEEE Control Systems Letters.

The 7 Greatest Adventures in Mathematics: Navier-Stokes Equations

How does water flow over a rapids? How does air flow around a car body? Is it possible to compute this? Is there a basic mathematical model for this, just as there are Newton's laws for the motion of solid bodies? A basic model of fluid mechanics are the Navier--Stokes equations. They are more complicated than Newton's laws and for complex applications one has to approximate them or resort to experiments (e.g. in a wind tunnel).

Student workshop in cooperation with the IFAS

This Monday, a student workshop in cooperation with the IFAS (Institut für Flugantriebe und Strömungsmaschinen) took place on the Automotive Research Centre Niedersachsen. We welcomed 25 students aged from 10 to 16 years.
