"Gradient-Enhanced Universal Kriging for Uncertainty Propagation in Nuclear Engineering"

B. A. Lockwood and M. Anitescu

VVUHPC 2010 Workshop, New Orleans, LA, . Also Preprint ANL/MCS-P1833-0111

Preprint Version: [pdf]

In this work, we investigate a surrogate for modeling the response of a simulated nuclear engineering system for use in uncertainty propagation. Building on our recent work using a gradient-enhanced regression approach, we examine the ability of a universal gradient-enhanced Kriging model to provide a means for inexpensive uncertainty quantification.
