When Crisp Theory is Disrupted by Messy Reality

In so many human endeavors, there is often a large gulf between an idea and the execution of that idea, between a philosophical ideal about how something works (or should work) and the implementation of a solution based upon this ideal meant to solve some problem. Every person in the world experiences this in some […]

Moving to Austria to Do Mathematics

Source - https://bar.wikipedia.org/wiki/Datei:Wiener-Schnitzel02.jpg

My name is Kirk Soodhalter. I am currently a research scientist at the Johann Radon Institute for Computational and Applied Mathematics and a consultant mathematician at the firm Mathconsult in Linz, Austria. Prior to this, I worked for four years as an assistant professor in the Industrial Mathematics Institute at Johannes Kepler University in Linz. […]

Celebrating the Radon Transform

A century ago, the paper  “Über die Bestimmung von Funktionen durch ihre Integralwerte längs gewisser Mannigfaltigkeiten” has been published by Johann Radon in Berichte über die Verhandlungen der Königlich-Sächsischen Gesellschaft der Wissenschaften zu Leipzig. Mathematisch-Physische Klasse, Band 69, 1917, Seiten 262–277, which laid, by the Radon transform, the basis of computerized tomography. From Marc 27 to March 31, […]

MICADO – First Light Instruments for the European Extremely Large Telescope (E-ELT)

by Roland Wagner, RICAM Apart from METIS, our group in Linz is also involved in the development of MICADO, the Multi-AO Imaging Camera for Deep Observations of the E-ELT. The consortium behind MICADO is led by the Max Planck Institute for Extraterrestrial Physics  (MPE). What is MICADO? The name MICADO is well-known in a slightly […]

Mathematics can be tough

voestalpine Grobblech is one of the world’s leading producers of heavy plates that find their applications in extreme conditions. Tough, HIC- and wear resistant as well as roll bonded clad plates are the focus of their product mix. To control the thermomechanical conditions during the production in an appropriate way, is one of the key […]

METIS – First Light Instruments for the European Extremely Large Telescope (E-ELT)

by Andreas Obereder, RICAM and MathConsult After the sucessful research project Mathematical Algorithms for E-ELT Adaptive Optics , the Linz Adaptive Optics team is now involved the development of two first light instruments for the E-ELT  In this blog entry, we focus on our contribution to METIS, the Mid-infrared E-ELT Imager and Spectrograph.

100 Years of the Radon Transform

Next year will be the 100th anniversary of the publication of the paper “Über die Bestimmung von Funktionen durch ihre Integralwerte längs gewisser Mannigfaltigkeiten” by Johann Radon. On the occasion of this anniversary the Johann Radon Institute for Computational and Applied Mathematics (RICAM) is organizing a conference with the title: 100 Years of the Radon […]

Laura and Sophia awarded

Young Talents is a programme organized by the Austrian research promotion agency (“Forschungsförderungsgesellschaft” FFG) and funded by the Austrian ministry for traffic, innovation and technology.  Talents internships for pupils aim to encourage girls and boys to follow natural sciences, and engineering and technology. Pupils have the opportunity to have an internship in various companies and […]

RICAM – The Johann Radon Institute for Computational and Applied Mathematics

The Johann Radon Institute for Computational and Applied Mathematics (RICAM), an institute of the Austrian Academy of Sciences, was founded in 2003 by Heinz W. Engl. RICAM focuses on basic research in applied mathematics, and within the Institute mathematicians from all around the globe collaborate on common core areas in mathematical modeling, simulation, inverse problems […]

Atmospheric Tomography in Adaptive Optics

Turbulent air motion in the Earth’ atmosphere causes index of refraction fluctuations. In atmospheric tomography one aims at reconstructing this atmospheric turbulence from light wavefronts of bright astronomical objects or laser beacons from several directions that are measured on the ground. Atmospheric tomography is needed in tomographic Adaptive Optics (AO) systems in large ground-based telescopes. […]
