Subspace-based dimension reduction for chemical kinetics applications with epistemic uncertainty
M. Vohra, A. Alexanderian, H. Guy +1
We focus on an efficient approach for quantification of uncertainty in complex chemical reaction networks with a large number of uncertain parameters. Parameter dimension reduction…

Sensitivity-driven adaptive construction of reduced-space surrogates
Manav Vohra, Alen Alexanderian, Cosmin Safta +1
We develop a systematic approach for surrogate model construction in reduced input parameter spaces. A sparse set of model evaluations in the original input space is used to approx…

Uncertainty Quantification in Non-Equilibrium Molecular Dynamics Simulations of Thermal Transport
Manav Vohra, Ali Yousefzadi Nobakht, Seungha Shin +1
Bulk thermal conductivity estimates based on predictions from non-equilibrium molecular dynamics (NEMD) using the so-called direct method are known to be severely under-predicted s…
