Modelling Ground Temperatures for the Climate Model LPJmL4

by 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 […]

Mathematics for Ophtalmology

by 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 […]

Atmospheric Tomography at Keck Telescope

by 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 […]

A multigrid method for elasto-hydrodynamic contact simulations of radial slider bearing

by 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 […]
