Fiala, N.C.; Haemers, W.H. - Tilburg University, Center for Economic Research - 2003

In this paper, we begin the determination of all primitive strongly regular graphs with chromatic number equal to 5.Using eigenvalue techniques, we show that there are at most 43 possible parameter sets for such a graph.For each parameter set, we must decide which strongly regular graphs, if...

Impact functions on the citation network of scientific articles

la Peña, José A. de - In: Journal of Informetrics 5 (2011) 4, pp. 565-573

Scientometric models, which consider papers in a undifferentiated way, are blind to important features of the citation network. We propose an approach for the definition of a function PS, for any set of scientific articles S, which reflects global properties of the citation network associated to...

Calculating near-singular eigenvalues of the neutron transport operator with arbitrary order anisotropic scattering

Van den Eynde, Gert; Beauwens, Robert; Mund, Ernest - In: Mathematics and Computers in Simulation (MATCOM) 80 (2010) 11, pp. 2216-2230

discrete eigenvalues with opposite sign associated to this separation procedure. In the case of arbitrary order anisotropic … scattering, there can be many more of those plus–minus pairs of discrete eigenvalues. When in a subsequent step, the … is of utmost importance to be able to find all discrete eigenvalues in order to have a complete set. In this paper we …

Eigenfactor and article influence scores in the Journal Citation Reports

Jacsó, Péter - In: Online Information Review 34 (2010) 2, pp. 339-348

Purpose – This sequel to the earlier testing and evaluation of the five‐year Journal Impact Factor (JIF‐5) in the enhanced version of the Journal Citation Reports ( JCR ) (released in January and July 2009 for the 2007 and 2008 journal collections, respectively) seeks to assess and compare...
