Figure 5
(a) Plot of NC values resulting from the criterion in equation (8)[link] for selected choices of c (3 ≤ c ≤ 6) versus the NC values determined by inspection of the NRCN(R) curves. (b) Variation in average and skewness of NC deviations for NC values determined according to equation (8)[link] relative to NC values determined visually from the NRCN(R) curves depending on the choice of the coefficient c. Both graphs refer to the analysis of the 64 cases mentioned in the text, where the proposed value of NC is sensitive to the choice of c, while the visual inspection appeared unambiguous.
