Uncertainty quantification in mechanics: A unified Bayesian perspective
Sascha Ranftl, Malte Rolf, Gerhard A. Holzapfel +1
Uncertainty quantification (UQ) is essential to experimental mechanics, but has become particularly relevant in computational mechanics, manifesting in two fundamental problem type…
Geometric Uncertainty of Patient-Specific Blood Vessels and its Impact on Aortic Hemodynamics
Domagoj Bošnjak, Richard Schussnig, Sascha Ranftl +2
In the context of numerical simulations of the vascular system, local geometric uncertainties have not yet been examined in sufficient detail due to model complexity and the associ…
Stochastic Modeling of Inhomogeneities in the Aortic Wall and Uncertainty Quantification using a Bayesian Encoder-Decoder Surrogate
Sascha Ranftl, Malte Rolf-Pissarczyk, Gloria Wolkerstorfer +4
Inhomogeneities in the aortic wall can lead to localized stress accumulations, possibly initiating dissection. In many cases, a dissection results from pathological changes such as…
Bayesian Surrogate Analysis and Uncertainty Propagation
Sascha Ranftl, Wolfgang von der Linden
The quantification of uncertainties of computer simulations due to input parameter uncertainties is paramount to assess a model's credibility. For computationally expensive simulat…
Bayesian Analysis of Femtosecond Pump-Probe Photoelectron-Photoion Coincidence Spectra with Fluctuating Laser Intensities
Pascal Heim, Michael Rumetshofer, Sascha Ranftl +4
This paper employs Bayesian probability theory for analyzing data generated in femtosecond pump-probe photoelectron-photoion coincidence (PEPICO) experiments. These experiments all…
Femtosecond photoexcitation dynamics inside a quantum solvent
Bernhard Thaler, Sascha Ranftl, Pascal Heim +6
The observation of chemical reactions on the time scale of the motion of electrons and nuclei has been made possible by lasers with ever shortened pulse lengths. Superfluid helium…
