Winter school “Applied mathematics: as useful as exciting”

Last week (02.03 – 06.03) took place in Kefermarkt the first winter school of the Austrian Study Foundation (Österreichische Studienstiftung). That was the fourth seminar organized by the Austrian Academy of Sciences (Österreichische Akademie der Wissenschaften) with the title “Applied mathematics: as useful as exciting”.

Selected pupils from schools around Austria had the possibility to learn and develop themselves applications of mathematics in everyday life. The four topics where: Financial mathematics, mathematical methods in Tomography, graph theory and mathematical modeling of sound.

Axel Kittenberger and Leonidas Mindrinos (University of Vienna) presented the fundamentals of the Radon transform, its properties and application to tomography. The students made 3D origami objects, image them with a system imitating an optical tomographic setup and then obtain the reconstructed pictures. Günter Auzinger (JKU Linz) addressed also the mathematics of sound propagation. The pupils had the opportunity to answer questions like: What makes the pitch of a musical instrument, what makes the sound and what does this mean for the human voice.

Front cover picture in “Inverse Problems”

 A figure from the research paper “Preconditioning Inverse Problems for Hyperbolic Equations with Applications to Photoacoustic Tomography” by Alexander Beigl, Otmar Scherzer, Jarle Sogn (JKU, Linz) and Walter Zulehner (JKU, Linz) got chosen for the front cover of the International Journal “Inverse Problems”. The picture appearing at the Volume 36, Number 1 of the journal presents initial source reconstructions from Photoacoustic Tomography data.

Presence in the celebration of University of Innsbruck 350th anniversary

Benedikt Pressl and Mia Kvåle Løvmo, members of the sub-project Imaging of Trapped Particles presented part of their work related to the SFB at the events “Campus Tage Technik” in April and “Fest der Wissenschaft” in June, as part of the 350th anniversary of the University of Innsbruck.

Scientists working at the Campus Technik presented aspects of their research (small presentations and experiments) to more than 1500 pupils. Benedikt was the coordinator and together with Mia, Franziska Strasser, Simon Moser, Alexander Jesacher, Lisa Bodner, Nicola Bregenzer and Martin Bawart gave hands-on experiments and exciting presentations about Optical tweezers and Lasers.

SFB goes to Banff, Canada

Otmar Scherzer was a member of the organizing committee of the “Reconstruction Methods for Inverse Problems” workshop in Banff, Canada, June 23-28, 2019. This workshop brought together researchers working on inverse problems coming from medical imaging, non destructive testing, computer vision and geophysics. The PI of sub-project “Quantitative Coupled Physics Imaging”, Peter Elbau and the post-doctoral researcher of the sub-project “Tomography with Uncertainties”, Ekaterina Sherina presented their recent work related to our SFB project.
