The Johann Radon Institute for Computational and Applied Mathematics (RICAM) of the Austrian Academyof Sciences (OeAW), Austria’s leading non-university research and science institution in AppliedMathematics, focuses on basic research in applied mathematics, and within the Institute mathematicians fromall around the globe collaborate on common core areas in mathematical modeling, simulation, […]
Read moreby Julia Niebsch Climate models are used to make predictions about the future development of the climate. These models use a variety of factors like aerial CO2 levels, sea temperatures and forestation to determine possible outcomes of the ongoing climate crisis. These physical and chemical processes can be described through […]
Read moreby Julia Shatokhina Optical coherence tomography (OCT) is a powerful interferometric technique providing non-invasive 3D imaging of sub-surface structures with resolutions on the micrometer scale. Significant developments of the OCT techniques in the recent decades were observed especially in biomedical applications. Thus, in ophthalmology the OCT imaging technique has revolutionized […]
Read moreby Stefan Raffetseder Using measurements of multiple guide stars in different directions inan Adaptive Optics system leads to the problem of atmospheric tomogra-phy. Usually, this problem is solved by an inverse matrix operation, whichrequires O (n2) operations. Since the new generation of ground-based tele-scopes have a diameter of 30m and […]
Read moreby Andreas Binder, Onkar Jadhav, and Volker Mehrmann, in: Journal of Mathematics in Industry, Volume 11 (8), 2021 Abstract This paper presents a model order reduction approach for large scale high dimensional parametric models arising in the analysis of financial risk. To understand the risks associated with a financial product, […]
Read moreby Michael Reichelt, Markus Windisch, Günter Offner, and Sarah Santner inETNA, Volume 54, pp. 355-369, 2021 Abstract The well-known Reynolds equation is typically used to compute the pressure distribution for elasto-hydrodynamic contacts of parts, as, for instance, in radial slider bearings. In order to resolve local pressure phenomena like edge […]
Read morenew accepted paper by Michael Kolmbauer, Günter Offner, Ralf Uwe Pfau, and Bernhard Pöchtrager Abstract This work is devoted to the efficient simulation of large multi-physicalnetworks stemming from automated modeling processes in system simulation soft-ware. The simulation of hybrid, battery and fuel cell electric vehicle applications re-quires the coupling of […]
Read moreSolving large linear systems in real-time applications by Bernadett Stadler In many practical examples solving large linear systems in real-time is the key issue. This is the case, e.g., for our ROMSOC project “Real Time Computing Methods for Adaptive Optics”, where we are dealing with a rapidly changing atmosphere of […]
Read moreby Onkar Jadhav I adore mathematics. There is mathematics everywhere: from how much pocket money I should save per day to buy that expensive toy as a kid to solving real-world problems as an adult. It is not just that mathematics helps solve problems; it is fun and intriguing as […]
Read moreWithin their program “Femtech Praktikum”, the Austrian Research Promotion Agency offers cofunding of internships at research companies to female students of natural or technical sciences. From November 2019 to April 2020, Judith Barth from Kepler University was such an intern at MathConsult, researching on constructing generating vectors of rank-1 lattice […]
