WebThe relative standard deviations (RSDs) were calculated to be in the range of 0.94%–2.08% for five repeated experiments. The limits of quantification (LOQs), based on signal-to-noise ratio (S/N) of 10, ranged from 0.12 to 3.53 µg/L, and the limits of detection (LODs), based on S/N of 3, ranged from 0.04 to 1.06 µg/L, which is very low by using GC–MS. The coefficient of variation (CV) is defined as the ratio of the standard deviation to the mean , It shows the extent of variability in relation to the mean of the population. The coefficient of variation should be computed only for data measured on scales that have a meaningful zero (ratio scale) and hence allow relative comparison of two measurements (i.e., division of one measurement by the other). The coefficient of variation may not have any meaning for data on an interval …
WebApr 10, 2024 · Fig. 9 shows the comparison results of the fractional core fission rates and their relative standard deviations (RSDs). One can see that both the dynamic weight window and the scale factor ensure relatively constant RSDs in an off-critical system by maintaining the ratio of the neutron weight to the weight bounds of the implicit capture in each time bin.
