When the period scale of nanostructure is more than the emitted wavelength, the transmittances decrease as the structure height increase.
An alternative, suggested here, is to introduce a sufficiently high upper truncation point to the flood distribution and modify the return period scale accordingly.
The truncation point is likely to be set as being above any physical upper bound and the return period scale will change only slightly over all practical return periods of operational interest.
The rightmost infinity tick point is therefore proposed, not as an operational measure, but rather to signal in flood plots that the return period scale does not extend indefinitely to the right.
The CV was evaluated by dividing the SD by the mean of the 21 time period scale scores.
These issues include the study design, analytical model, time period, scale of analysis, exposure variables and other factors associated with dengue transmission as illustrated below.
Similar to the original SCOPA-DC, [ 22] CV scores were not evaluated if the time period scale mean was below one.
One approach that is more suitable in terms of frequency spacing is the integer period DFT [ 21], and while this is able to identify the period expected from the NPS on a linear-period scale it too has problems.
Significance testing was not conducted if the sample size was less than 5. Longitudinal binary logistic regression using generalized estimating equations (GEE) [ 38] was used to assess the relationship between single-period scale scores and the probability of experiencing off-time.
For weak perturbation of the system by additive noise, [244] find that the heteroclinic cycle is approximated by a roughly periodic transition around the cycle whose approximate period scales as the logarithm of the noise amplitude.
