2A shows a series of horizontal isocontour lines that depict how a positive bias up to +2 ng/L is associated with misclassification of data from the initial <2-ng/L category to the [greater than or equal to] 2-ng/L category.
The pattern of isocontour lines is similar to the pattern in Fig.
Isocontour lines of misclassification rates at the 52-ng/L threshold are very close to the pattern observed for the 26.
The three-dimensional borehole thermal resistances calculated under variations of the pipe spacing and the grout thermal conductivity were plotted on surface charts illustrating the distribution of resistances and the predicted value was emphasized with a continuous isocontour line (Figure 6).
3 shows that each isocontour connectivity of a bilinear function on a face is preserved for any possible triangular mesh generated from our decomposition rule.
3), the PL isocontour on each face is topologically correct.
For example, to determine the maximum percentage of 1-category dosing errors found under the 10% TEa condition, simply determine the isocontour line with highest dosing error that crosses the 10% TEa condition boundary (Fig.
Increasing bias had little effect on the rate of [greater than or equal to] 3-category dosing errors, which can be appreciated by observing that the error isocontour lines change little as a function of increasing bias.
Figures 17-19 show the mean flow streamlines and the isocontours of the kinetic energy of turbulence in the cross-planes normal to the main flow direction at three streamwise locations: x = 80 mm (corresponding to the separation region immediately behind the car body), 200 mm (coinciding with the "free" reattachment point) and 500 mm (situated in the far wake) obtained experimentally and computationally; see Fig.
The MP and mP streamwise mean velocity isocontours given in Fig.
Even if the model predicts the axis-switching phenomenon, the isocontours comparison reveals that the spatial distribution of the flow is not perfectly predicted by the model: the inner contours are tight and contraction/expansion in the MP/mP is more pronounced than in reality.
In these figures, isocontours of the scattered intensity are displayed in various shades of gray.
