Shortcut nitrification was reported to be technically feasible and economically favourable, especially when sewages with high ammonium concentrations or low C/N ratios are treated....
: This paper addresses the problem of maximizing the service lifetime of a distributed battery-powered sensor network in the context of the network interdiction problem under user-...
Abstract. We extend the common depth-first backtrack search for constraint satisfaction problems with randomized variable and value selection. The resulting methods are applied to ...
Abstract. Given a simple n-sided polygon in the plane with a boundary partitioned into subchains some of which are convex and colored, we consider the following problem: Which is t...
In this paper we consider the problem of nding a core of limited length in a tree. A core is a path, which minimizes the sum of the distances to all nodes in the tree. This proble...
