Generating all graph coverings by permutation voltage assignments
Discrete Mathematics, 1977 AbstractThis paper introduces the permutation voltage graph construction, which is a generalization of Gross's ordinary voltage graph construction. It is shown that every covering of a given graph arises from some permutation voltage assignment in a symmetric group and that every regular covering (in the topological sense) arises from some ordinary ...

Graph Convolutional Network Based Fault Detection and Identification for Low-voltage DC Microgrid [PDF]
Journal of Modern Power Systems and Clean Energy, 2023 This paper presents a novel fault detection and identification method for low-voltage direct current (DC) microgrid with meshed configuration. The proposed method is based on graph convolutional network (GCN), which utilizes the explicit spatial ...

Some voltage graph-based LDPC tailbiting codes with large girth [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 The relation between the parity-check matrices of quasi-cyclic (QC) low-density parity-check (LDPC) codes and the biadjacency matrices of bipartite graphs supports searching for powerful LDPC block codes. Algorithms for searching iteratively for LDPC block codes with large girth are presented and constructions based on Steiner Triple Systems and short ...

A contribution to the theory of voltage graphs
Discrete Mathematics, 1986 AbstractVoltage graphs, one of the main tools for constructing graph embeddings, appear to be useful in various areas of graph theory and combinatorics.The present paper concerns several problems in voltage graph theory such as equivalence and regularity of coverings generated by (permutation) voltage graphs, automorphism groups and some other things.

Characteristic polynomials of graph bundles having voltages in a dihedral group
Linear Algebra and its Applications, 2001 AbstractIn this paper, we compute the characteristic polynomial of a graph bundle when its voltages lie in a dihedral group, as the first attempt to compute the characteristic polynomial of a graph bundle (also, of a graph covering) having voltages in a nonabelian group.

The medial graph and voltage- current duality
Discrete Mathematics, 1992 AbstractThe theories of current graphs and voltage graphs give powerful methods for constructing graph embeddings and branched coverings of surfaces. Gross and Alpert first showed that these two theories were dual, that is, that a current assignment on an embedded graph was equivalent to a voltage assignment on the embedded dual.

Approach for modelling of broadband low‐voltage PLC channels using graph theory [PDF]
IET Communications, 2018 Broadband power line is an important way of communication in low-voltage distribution networks because a power line is everywhere nowadays. However, due to the heterogeneity of a practical power-line network and various loads connected to its termination
