Each group is described by its centroid and mean orientation.
Right: Recombination of segments s and s generates a new segment s with edge orientation which changes the total dislocation density and mean orientation.
Following that, various statistical and geometric measures are calculated from the discretized segments, including distribution of turning angles and mean orientation vectors.
The small-angle X-ray scattering studies showed that the degree of anisotropy and mean orientation angles of clay platelets in blend matrix were altered significantly after frequency and temperature sweep tests.
The mean orientation recorded under overcast skies in the local geomagnetic field was for all three species directed south to southeast (Fig. 1B, Fig. 2B, Fig. 3B; Table 2).
On average both B/Y and R/G populations showed mild orientation selectivity for achromatic gratings (mean orientation index for B/Y cells, 0.144 ± 0.130, n = 9; mean for R/G cells, 0.105 ± 0.081, n = 29; P = 0.81, Wilcoxon paired rank-sum test).
means direct orientation; - reverse orientation of the AuxREP&S elements.
In this manner, more negative mean orientation difference scores indicate a relative tendency to orient toward an upcoming left turn during later trials, and more positive path efficiency scores indicate higher path efficiency during later trials.
Mean orientation of the lines is N37.5°W.
The distribution is arranged to set the mean orientation = 90°, corresponding to the mean orientation of the lineation.
The magnitude of the mean orientation vector indicates the directedness of an insect's path.
