Trier and Heidelberg SIAM Chapter members

Five doctoral students of the Interdisciplinary Center for Scientific Computing (IWR) at Heidelberg University founded the Heidelberg Chapter of SIAM at the end of 2011. In the meantime, the group has grown to the largest German Student Chapter and celebrated its Opening Ceremony on March 29. With generous support of SIAM, IWR and the Heidelberg Graduate School HGS MathComp, the event was a bright success, attracting both participants from industry as well as renowned scientists of Heidelberg University.

Dörte Beigel and Andreas Sommer are excited: “We have expected about 50 participants to attend, finally it have been more than 70!” The two were responsible for the organization of the opening event. The remaining members of the executive board of the Heidelberg Chapter of SIAM, Kathrin Hatz, Holger Diedam and Dennis Janka, returned just in time from Hanoi, Vietnam, where they had given a lecture and support for foundation of a new SIAM student chapter.

Holger Diedam welcomed the invited guest speaker Jürgen Hairbucher from Intel, as well as the numerous attending guests, among them the co-founder of the IWR Prof. Jürgen Wolfrum and five representatives of the second German SIAM-Chapter of Trier University, and shortly summarized the activities of the newly founded Heidelberg Chapter: “The main goal of our Chapter is to foster the bilateral exchange of industry and academia, as well as strenghening the cooperation between young scientists worldwide.”

Prof. Rolf Rannacher, dean of the faculty of mathematics and computer science at Heidelberg University, gave a detailed introduction on the wide fields of application of mathematical methods developed at IWR, which range from sattelite orbit determination and optimization of chemical reaction networks to simulation of blood in human heart vessels and automated reconstruction of the cambodian Angkor Wat temple from 3d surface scans – to give just a few examples.

Guest speaker Jürgen Hairbucher, director of the Intel Open Lab Munich and jointly responsible for coordination of Intel’s research and development in the European Union, described Intel’s vision for 2020. The semiconductor giant runs a variety of research, including the areas energy efficiency, mobility and image processing, often in collaboration with universities.

Three selected talks describing the state-of-the-art reseach at IWR marked the ending of the scientific part of the opening ceremony. Dr. Mario Mommer gave a presentation on mathematical modeling and simulation of subdiffusion (transport in porous media), that occurs in living cells. Also dealing with medical applications, Dr. Thomas Wick illuminated in his talk the formation of cardio-vascular diseases as a result of disturbed blood circulation.

The audience award, if there had been one, would go to Simon Lenz. In his talk titled “Delay Effects in the Livescore of ‘Unser Star für Baku’ (USfB)”, he bridged the gap between science and everyday’s life in the most entertaining way (USfB was the 2012 TV show to determine Germany’s candidate for the Eurovision Song Contest that reaches 100-600 million viewers internationally; the ‘Livescore’ in USfB showed the current ranking of each candidate and was continuously updated by incoming votes). He figured out why the crowd-pleaser Roman Lob who finally won the German final almost failed in the first show despite a tremendous performance. “The mathematical analysis clearly shows that two major effects lead to the unwanted outcome: First, the technical delay between broadcasting the television signal and the incoming of votes, and second, the ‘laziness’ of the viewers that only called if their favorite was acutely in danger of being eliminated” explained Simon Lenz. As a result of this voting system, even an outstanding performer could easily fail, just because his supporters recognize too late that he is in danger being voted off the show. Obviously, also the producers of USfB noticed these problems and modified the voting system after the third show.


The Heidelberg Chapter of SIAM cordially invites all mathematically interested people in the Heidelberg Area to its Opening Ceremony on March 29. 

As our special guest, we are proud to announce Mr. Jürgen Hairbucher, Director of the Intel Open Lab Munich, who will give a talk about the interconnections between industry and academia.

The Intel Open Lab Munich, together with a sister lab in Ireland, coordinates the Research and Development activities of more than 1000 scientists across the European Union. 

We are also very happy to announce that Prof. Rolf Rannacher, Dean of the Faculty of Mathematics and Computer Science of Heidelberg University, will give an overview about research projects and applications at IWR in an introductory session.

The rich scope of research at IWR will be outlined in three selected talks of Chapter members (see schedule below). A subsequent reception with buffet and refreshments at the Common Room gives the opportunity for discussion.
