Focus of power system engineers is currently directed to the impact of wind power on variation in frequency of system.
A statistical post-hoc analysis on 28-day hospital mortality was performed to assess the power of mortality variation among the years, and showed a power of less than 50%, so the variation of mortality over years should be interpreted with caution.
We found that the luminance contrast is the variable with the most explanatory power of the variation in foraging efficiency among fruit species.
Our findings shown here illustrate the power of natural variation approaches and support ELF3 as a negative regulator of ambient temperature signaling.
This method can be used to exploit the power of the variation in individual recombination frequency, to shed light on the regulatory system of recombination hotspots.
The second aim of our paper consisted on estimating the statistical power of the variation statistics, and our results are consistent with Diehr's [ 9].
The discriminating power of cpDNA variation was particularly low for the cultivated olive tree with one predominating haplotype, but more diversity was detected in wild populations.
We performed a power calculation in Quanto (Version 1.2.4, May 2009) (Gauderman & Morrison, 2006) to estimate the power of detecting variation in the mean normalized PiB uptake that can be explained by genetic factors.
Our study aims at 1) determining whether variation in utilization rates between health areas is higher than would be expected by chance, 2) estimating the statistical power of the variation statistics; and 3) evaluating the ability of different statistics to compare the variability among different procedures regardless of their rates.
The convergence of orbital variations would be "a very reasonable explanation" for the glacial boundary event, says paleoclimate modeler Thomas Crowley of Texas A&M University in College Station, as well as further support for the power of orbital variations to influence climate.
