Abscissa and ordinate a parametric equation. Used in this way, the abscissa can be thought of as a coordinate-geometry analog to the independent variable in a mathematical model or experiment (with any ordinates filling a role analogous to dependent variables). Abscissa and ordinate In mathematics, the abscissa (; plural "abscissae" or "abscissæ" or "abscissas") and the ordinate are respectively the first and second coordinate of a point in a coordinate system. The abscissa of a point is the signed measure of its projection on the primary axis, whose absolute value is the distance between the projection and the origin of the axis, and
Biased random walk on a graph total number of the shortest paths between all pairs of nodes that pass through the node formula_14. In fact the walker prefers the nodes with higher betweenness centrality which is defined as below: Based on the above equation, the recurrence time to a node in the biased walk is given by: Variety of applications by using biased random walks on graphs have been developed; control of diffusion, advertisement of products on social networks, explaining dispersal and population redistribution of animals and micro-organisms, community detections, wireless networks, search engines and so on.
