Targeted sample size of 50 was calculated based on a power analysis for the above repeated measures analysis using G*Power 3.1 software, estimating a medium effect size, α = .05, power = 0.8, two groups, two measurements, correlation between measures = 0.5, and nonsphericity correction = 1.
Even though the dry porous sand at the site made the measurements difficult and the earthing impedance measurements were made four years and longer after system installation and current measurements, correlation was also found between the measured impedance and the measured current distribution.
In contrast to earlier amplitude fluctuation measurements, correlation time lags across an intercontinental baseline may reach several tens of seconds.
Based on the measurements correlation equations were developed to calculate the convective heat-transfer coefficient for any corrugation ratio, which allows us to simplify the design of local ventilation devices.
When using the GE and WB abundance measurements, correlation coefficients have absolute values of less than 0.05 and P-values are greater than 0.22.
This adapted model shows a good agreement between modelled values and actual measurements (correlation coefficient for daily means > 0.80).

With these new measurements, correlations of bubble properties can be developed to reliably scale-up bubbling fluidized beds with vertical internals.
Including all measurements, correlations between data pairs were established using linear regression analysis and are expressed as the square of Pearson's correlation coefficients (r).
An extended random decrement method, which considers the measurement correlation, was first employed to reduce the measured dynamic responses of the building.
A multilevel model is established to simultaneously account for measurement correlation within the same test section and roughness evolution correlation within the same experimental site.
However, this assumption may not hold in practice, due to the unavoidable measurement correlation existing in most real-world applications.
