   Natural Alternatives For One Dimensional Median Filtering

   Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: C.H. Rohwer M. Wild

   For practical purposes median smoothers have often been considered the basic components for the construction of simple non-linear smoothers for removing impulsive noise before any subsequent linear signal extraction from a sequence. Alternatives exist that are computationally convenient, conceptually simpler...

   A Transition from Total Domination in Graphs to Transversals in Hypergraphs

   Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: MichaelA. Henning Anders Yeo

   A set S of vertices in a graph G without isolated vertices is a total dominating set of G if every vertex of G is adjacent to a vertex in S. The total domination number of G is the minimum...
