Discovering the complex relationships between entities is one way of benefitting from the Semantic Web. This paper discusses new approaches to implementing -operators into RDF quer...
Let G be a nonsingular connected mixed graph. We determine the mixed graphs G on at least seven vertices with exactly two Laplacian eigenvalues greater than 2. In addition, all mi...

The set of all orientations of a planar graph with prescribed outdegrees carries the structure of a distributive lattice. This general theorem is proven in the first part of the p...
Revision history provides a rich source of information to improve the understanding of changes made to programs, but it yields only limited insight into how these changes occurred...
In the present paper, we introduce a multi-user interactive framework for solving complex optimization problems. The framework, called Co-UserHints, provides a visual computationa...
