Dynamics of distributed sources is described by nonlinear partial differential equations. Lagrangian analytical solutions of these (and associated) equations are obtained and discussed in the context of the Lagrangian mod-eling-from the Lagrangian Invariants to dynamics. Possible applications of distributed sources and sinks to geophysical fluid dynamics and to gravitation are indicated. Singul...

In this article we present an algorithm for converting a network problem with several sources and several sinks including several transfer nodes and condition of supplying the demand of any sink from a particular source to the transportation problem.  Towards this end, and considering the very special structure of transportation algorithm, after implementing the shortest path algorithm or ...

We give algorithms to find the optimal disjoint paths around a rectangle. The set of disjoint paths connects a set of sources to a set of sinks (no fixed pairing between the sources and sinks) on the boundary of a rectangle where either the longest path length or the total path length is minimized. One algorithm finds the set of disjoint paths with the longest path length minimized in O(n log n...

Floodplain soils and reservoir sediments are known for their fine-grained structure rich organic-matter substances; therefore, they able to sorb metals other potential pollutants, which is characteristic of sink function [...]
