Abstract:
|
The Virtual Cement and Concrete Testing Laboratory (VCCTL) is a software system, being developed at the National Institute of Standards and Technology, that is to be used for evaluation and testing of new cement mixtures. This presentation will describe Bayesian statistical modeling of the virtual measurements which uses information from related physical measurements and models. The use of these statistical models, for validation of the software, and for computation of uncertainty estimates for the virtual measurements, will be described.
