Validation, Uncertainty Quantification and Uncertainty Reduction for a Shock Tube Simulation

18th AIAA Non-Deterministic Approaches Conference, 2016
While we rely on simulations to predict the response of complex systems, we recognize that the models that underlie these simulations are never perfect. Comparison of simulations with experiments is an important tool for exposing limitations of models, and providing insights into which models need improvement.

Dimensionality reduction can be used as a surrogate model for high-dimensional forward uncertainty quantification

open access: yesReliability Engineering and System Safety
We introduce a method to construct a stochastic surrogate model from the results of dimensionality reduction in forward uncertainty quantification. The hypothesis is that the high-dimensional input augmented by the output of a computational model admits ...

Quantification and Reduction of Uncertainties in 3D Stress Models

2020
<p>The undisturbed stress state of a potential site for nuclear waste disposal is of key importance for the assessment of long-term stability of the geotechnical installations and for seismic hazard assessment. In particular, the stability of pre-existing faults within and near a repository can only be evaluated with the ...

Use of Emulator Methodology for Uncertainty Reduction Quantification

SPE Latin America and Caribbean Petroleum Engineering Conference, 2014
Abstract In petroleum engineering, simulation models are used in the reservoir performance prediction and in the decision making process. These models are complex systems, typically characterized by a vast number of input parameters. Usually the physical state of the reservoir is highly uncertain, and thus the appropriate parameters of ...
