WebA flow net is a graphical representation of two-dimensional steady-state groundwater flow through aquifers.. Construction of a flow net is often used for solving groundwater flow … WebThe current-flow betweenness of a vertex v is defined as the amount of current that flows through v in this setup, averaged over all vertex pairs s and t. The current-flow betweenness of a vertex v is the average of the current flow over all source–target pairs: where n (n − 1)/2 is a normalizing constant, and I v(st) is the current flow ...

WebNormalized flow betweenness Normalize the raw flow betweenness by the total maximum flow among third parties (including v); this leads to the following normalized flow betweenness measure: Variant by Koschutzki et al. where 0/0 flow ratios are treated as 0 (as in shortest-path betweenness). WebAbstract. We consider variations of two well-known centrality measures, betweenness and closeness, with a different model of information spread. Rather than along shortest paths only, it is assumed that information spreads efficiently like an electrical current. We prove that the current-flow variant of closeness centrality is identical with ...
