An approach to extract watersheds and watercourses, as well as their corresponding valleys and hills, from images with subpixel precision is proposed. The critical points of the t...
Abstract: In several rule-based applications using graph transformation as underlying modeling technique the following questions arise: How can one be sure that a specific sequence...
Numerous recent papers have found important relationships between network structure and risks within networks. These results indicate that network structure can dramatically affec...

Abstract. We study the lattice structure of sets (monoids) of surjective hyper-operations on an n-element domain. Through a Galois connection, these monoids form the algebraic coun...
This paper is devoted to the following incremental problem. Initially, a graph and a distinguished subset of vertices, called initial group, are given. This group is connected by ...
