The area moment of inertia can be computed by dividing the cross-section into area elements, dA, and multiplying each area by the square of their distance, y, from the neutral axis (dotted line).
Therefore, the error matrix in terms of estimated area proportions, where accuracy can be computed directly, was calculated using Eq. 1 (Table 3).
By placing the object inside a rectangle and then throwing darts at the rectangle, the area of the odd shape can be computed by taking the area of the rectangle and multiplying it by the percentage of darts falling within the rectangle.
In addition to flood incident reports, valuable hydraulic data such as the extent and depths of inundated areas and flow rate estimates can be computed using messages, photos and videos produced by citizens.
By dividing it up into a correspondingly infinite number of triangles, its area, as for any regular polygon, can be computed as half the product of the apothem (in this case identical with the radius of the circle), and the perimeter.
Suppose that the distance of the block center to the image center O is R1, the block is a square in size a × a, then the overlapped area (public pixels) between □ABCD and □EFGH can be computed as: S P K N G L D = 1 2 ( A K ¯ + L G ¯ ) 1 + 1 cos θ ⋅ a - 1 2 ⋅ | ( A K ¯ | 2 + L G ¯ | 2 ) ⋅ tan θ, (14).
Once the co-segmentation is complete, changes in cell area or gene expression over the interval between two time points can be computed and visualized as a heatmap.
An overall marginality coefficient can be computed over all EGVs, so that the marginalities of different species within a given study area can be directly compared.
The needed average values can be computed by summing over the individualized values calculable for study subjects inside the spatial study area during the same time period.
