BackgroundPersonalized hemodynamic models can accurately compute fractional flow reserve (FFR) from coronary angiograms and clinical measurements (FFRbaseline), but obtaining patient-specific data could be challenging and sometimes not feasible. Unde

What is ab initio in nuclear theory?

Autor: Ekström, Andreas, Forssén, Christian, Hagen, G., Jansen, G. R., Jiang, Weiguang, Papenbrock, T.

Publikováno v: Frontiers in Physics vol.11(2023)

Ab initio has been used as a label in nuclear theory for over two decades. Its meaning has evolved and broadened over the years. We present our interpretation, briefly review its historical use, and discuss its present-day relation to theoretical unc

SIAM/ASA Journal on Uncertainty Quantification, ASA, American Statistical Association, 2019, 7 (4), pp. 1323-1348. ⟨10.1137/18M1216389⟩

International audience; Crude and quasi Monte Carlo (MC) sampling techniques are common tools dedicated to estimating statistics (expectation, variance, covariance) of a random quantity of interest.We focus here on the uncertainty quantification fram

Fast Uncertainty Quantification in Low Frequency Electromagnetic Problems by an Integral Equation Method Based on Hierarchical Matrix Compression

Autor: Federico Moro, Luca Di Rienzo, Riccardo Torchio, Lorenzo Codecasa

Publikováno v: IEEE Access, Vol 7, Pp 163919-163932 (2019)

A parametric model order reduction method combined with a polynomial spectral approximation is applied for the first time to a Volume Integral Equation method accelerated by a low-rank matrix compression technique. Such an approach allows for drastic

Displacement uncertainties with multiview correlation schemes

Autor: François Hild, Stéphane Roux

Publikováno v: Journal of Strain Analysis for Engineering Design
Journal of Strain Analysis for Engineering Design, SAGE Publications, 2020, 55 (7-8), pp.199-211. ⟨10.1177/0309324720927102⟩

International audience; Multiview correlation is based on the use of explicitly parameterizing surfaces whose deformation is to be measured. In the present analyses, the surfaces are modeled as triangular facets (for local approaches), and with finit
