2018 Introduction to thermal-mechanical lithosphere models with surface processes
04 Feb 2021 | Contributor(s): Louis Moresi, Romain Beucher
Surface processes including erosion, transport and sedimentation have the potential to strongly influence crustal and lithospheric deformation whether passively, through isostatic response, or more actively by affecting the thermal structure, the potential energy field, and / or the local stress...

2016 Uncertainty Quantification in Computational Models of Physical Systems
04 Feb 2021 | Contributor(s): Habib Najm
Models of physical systems typically involve inputs/parameters that are determined from empirical measurements, and therefore exhibit a certain degree of uncertainty. Estimating the propagation of this uncertainty into computational model output predictions is crucial for purposes...
