Therefore, the probability of the packet passing through is a weighted average of all sub-flows multiplied by the corresponding dropping probabilities: $$\begin{aligned} p_{P}(t) \ =\ \frac{\Sigma _{i=0}^{n} w_{i}(t)(1-p_{i}(t))}{\Sigma _{i=0}^{n} (w_{i}(t))} \...
The formula for calculating the area of a triangle is (length * height)/2. Thus, the syntax of the formula for finding the area of a triangle in Excel would become: =(<cell with length>*<cell with height>)/2 Eg. Let us consider the length and height in columns A and B as in ...

This study takes the research area as the data support and fuses the features by means of weighted average. The formula is as follows: (5) where cfi, Wi represent the eigenvector value of class i of POI and microblog check-in; n represents the number of eigenvector values of each ...
Landscape metricFormulaDescription Mean of patch area AREA_MN=∑i=1naijN aijis the area of a certain patch type, and N is the number of patches. The average area of a patch with the same type, and its value affects the type and abundance of species within the patches. Area-weighted me...
As a final step of the process, ECL is obtained as a weighted average of ECL1,…,ECLk, estimated by relying on alternative scenarios. For CECL, if only one scenario is used, ECL is estimated as part of the previous step: ECL computation for each scenario. All these components are furth...
