The formula, based on average annual rainfall as an index, can be easily applied to non-recording rain gauges. This paper further applies the mean value first-order second moment (MFOSM) method to estimate the uncertainty of the proposed regional IDF formula. From a stochastic viewpoint,...

To inspect the impact of economic uncertainty on economic growth in Pakistan, the data were collected from 2011M1 to 2020M5. The summary statistics for the related variables IPI and EPU are presented in Table 1. The mean value of both variables is close, which shows that there is a symmetr...
Finally, the node is split into two daughter nodes, so the mean square error is minimized. This way, randomness is introduced into the decision trees via predictors and via sample. (ii) The ensemble \(\left\{ {T_{i} ,{ }i = 1, \ldots ,M} \right\}\) of \(M\) decision ...
Fig. 12 presents the distribution of the decay heats calculated by each operating condition with a p-value. All cases followed the normal distribution (i.e., p-value > 0.05), and the mean values of the three distributions were the same as the nominal value. Download: Download high-res ...
19, or more general correction schemes described by Aykol and Wolverton23 and the recent “Coordination-Corrected Formation Enthalpy” (CCE) method of Friedrich et al.16. By fitting energy corrections to experimental data, such empirical DFT correction schemes can reduce the mean absolute errors (...
The uncertainty of real-time PCR measurements is primarily composed of two components, calibrator uncertainty and measurement process uncertainty; both these components are assumed to follow a normal distribution14,15. Therefore, measurement results are represented by the mean DNA concentration of each sa...
because the electron can make atransitionto another state, the initial state has a finite lifetime. The transition is a random process, and so different atoms in the same state have different lifetimes. If the mean lifetime is denoted as τ, the theory shows that the energy of the initial...
A commonly used performance evalu- ation system in object detection is mean average precision (mAP). In the mAP evaluation system, all the prediction boxes of the same category are sorted according to their confidence levels. Then, the intersection over union (IoU) of the prediction and the ...
The reference shape perimeter is calculated by the mean of the outer face lengths multiplied by the number of input dimensions. This creates a regular polygon, for which the apothem (line from centre to midpoint of each side) is given by Eq. (5). This is then used to calculate the ref...
