Table 3.
The expected values of the model parameters are taken from ultrasonic measurements performed on a flat and parallel block of Lexan. These expected values are compared to the means and standard deviations of the Monte Carlo samples computed using Bayesian probability theory for the data acquired on a block of Lexan with a step discontinuity.
