Hence, to improve on this fairness for all UEs irrespective of location, the harmonic mean metric is hereby proposed.
Park and Park [70] extend the works Sun and Sun [61] by considering the interactions of any three aggregated arguments instead of any two to develop generalized fuzzy weighted Bonferroni harmonic mean (GFWBHM) operator and generalized fuzzy ordered weighted Bonferroni harmonic mean (GFOWBHM) operator.
p] means are reduced to ordinary arithmetic, geometric, and harmonic mean, respectively.
While the arithmetic and geometric means are ill-suited--mathematically undefined--to the kind of change in prices suggested by these scenarios, the harmonic mean converges to 2[p.
Since the generalized contra harmonic mean is monotonically increasing and hence we have
The kernel estimators (using all combinations of reference and cross-validated bandwidth selection, and fixed and adaptive bandwidths) were compared to the harmonic mean estimator for the ability to reproduce the original distribution.
Specifically, the harmonic mean is the only one that provides an accurate relationship to the actual time required to execute the benchmark programs.
In MBES, instead of using the average throughput as the conventional approaches, the harmonic mean technique [20] is used to smooth the slight fluctuation of estimating available bandwidth in the stable state area.
From which we find that DF is equal to the harmonic mean of x and y.
The conventional way of treating varying population size in population genetic models has been to use the harmonic mean of population sizes over time as an approximation (Wright 1938; Karlin 1968; Whitlock 1992).
Assuming that other factors are approximately constant over time, then a simpler approach is to use the harmonic mean of N to estimate the average [N.
If variation in N among species within a higher taxon reflects the history of any one species, then all species will eventually be bottlenecked to the smallest N and the harmonic mean is better.
