The analysis of a worldwide database of daily discharge and the calculation of the pairwise statistical dependence, via the Kendall’s tau and Spearman’s rho, between peak, volume, and duration of flood events, selected with a threshold-based approach and a criterion of temporal independence ...
scaling (to zero mean and unit variance), 10-fold cross validation, and probability calculation. The probability is calculated by fitting a logistic distribution using maximum likelihood to the decision values of all binary classifiers, and computing the a-posteriori class probabilities for the multi-...
An exact measure of average peak-to-peak amplitude would require the measurement of every wave and the calculation of their average. To do this manually it is necessary to have a set of rules so that there is no ambiguity about which waves to include and which to ignore. This method is ...
In addition, the most ideal grid operation in accordance with the conditions determined by calculation and decision mechanisms with big data processing capacity will be provided. In these systems, a large number of components, which are located at different points, are of very different character ...
One calculation by climate scientists, in an attempt to quantify the impact of this loss of albedo, have stated that the warming impact will be equivalent to all the fossil fuels burned since the early 1990’s. A second factor concerns the latent heat of ice. A great deal of heat is ...
The Post-fire Composite Hazard Ranking will be used as the basis for targeting small watersheds for post-fire treatments. The results of this calculation were ranked from 1 (lowest Post-fire Composite Hazard) to 5 (highest Post-fire Composite Hazard) to create the Post-fire Composite Hazard ...
It is a chilling calculation, because it is a figure 41% lower than the current and 57% less than the 10,000 million expected in 50 years. Now we begin to understand what being a finch in Daphne Mayor at the end of a wet year. Fig. 12. Representation of the global ecological foot...
It would need to have the reverse energy calculation included to have real meaning. This reverse calculation being the energy from renewables needed to capture carbon and make the basis for all these products, like Haru Oni is making synthetic fuels (except they haven’t got the carbon capture...
Calculation of power in the general linear model scenario is slightly more complicated as it requires distribution assumptions and approximations. To do so define Cohen's f2 to bef2:=R21−R2=mN−pF=(Cβˆ)T(C(1N−pXTX)−1CT)−1(Cβˆ)σˆ2.where R2 is the partial coeffic...
• We identify several critical methodological and calculation flaws in that paper. • We discuss such flaws in detail and rebut Ferroni and Hopkirk’s conclusions. • We provide revised EROI calculations with both conventional and extended boundaries. https://www.sciencedirect.com/science/arti...
