  1. A Gentle Introduction to Uncertainty Quantification

    19 Aug 2016 | | Contributor(s):: Ilias Bilionis

  2. Efficient Exploration of Quantified Uncertainty in Granular Crystals

    16 Mar 2016 | | Contributor(s):: Juan Camilo Lopez

    This work presents a way of quantifying uncertainty in granular crystals in a computationally efficient way. To accomplish this, a low dimensional response surface is approximated through the method of active subspaces. Within this framework, special structure within the inputs is exploited to...

  9. Quantifying the Influence of Conformational Uncertainty in Biomolecular Solvation Using a L1 Minimization with Basis Rotation Algorithm

    16 Dec 2015 | | Contributor(s):: Guang Lin

    Biomolecules exhibit conformation fluctuations near equilibrium states, inducing uncertainty in various biological properties. We have developed a L1 minimization with basis rotation algorithm to quantify this uncertainty using a generalized polynomial chaos expansion on collective variables...

  10. Quantifying Uncertainties in Physical Models

    28 Aug 2017 | | Contributor(s):: Ilias Bilionis

    Increasing modeling detail is not necessarily correlated with increasing predictive ability. Setting modeling and numerical discretization errors aside, the more detailed a model gets, the larger the number of parameters required to accurately specify its initial/boundary conditions, constitutive...
