Uncertainty Quantification of Microstructural Properties due to Experimental Variations

Experimental Investigation of Bed Variations due to Circular Culvert Jet with Different Angles

Downfall flows from different outlet hydraulic structures such as culverts and jetsthrowingtothe erodible downstream bed cause scour hole and changes in the downstream bed topography. Therefore,by performing some physical modeling tests on culvert jet flow under different angles, changes in the downstream bed topography under the effect of different parameters such as flow rate, depth of the ta...

Quantification of Uncertainty Due to Subgrid Heterogeneity in Reservoir Models

Due to the lack of data, a reservoir engineer needs to calibrate unknown petrophysical parameters based on production history. However, because the observations cannot constrain all the subsurface properties over a field, production forecasts for reservoirs are essentially uncertain. In general, many parameters of the model must be adjusted in the historymatching process, and the amount of comp...

Quantification of Experimental Uncertainty in Design Analysis

Uncertainty, being an integral part of any test, experiment or manufacturing process, can be declared as the foremost runner to be analyzed in design analysis. Uncertainty analysis coupled with probability of failure for a component or system gives us enough fuel to ride on towards the optimization process. However, Experimental uncertainty is also a kind of uncertainty which is ignored in mode...

Uncertainty Quantification and Model Validation under Epistemic Uncertainty due to Sparse and Imprecise data

This paper develops a methodology for uncertainty quantification and model validation in the presence of epistemic uncertainty due to sparse and imprecise data. Three types of epistemic uncertainty regarding input random variables – interval data, sparse point data, and probability distributions with parameter uncertainty – are considered. When the model inputs are described using sparse point ...
