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 ...

Voltage relaxation curve‐based state of charge estimation method with reduced measurement time
Electronics Letters, 2023 This paper proposes a method for estimating a battery's State of Charge using voltage relaxation curves. This method offers advantages over the conventional State of Charge estimation methods by reducing the measurement time of the Open Circuit Voltage ...

Desynchronization: Synthesis of asynchronous circuits from synchronous specifications [PDF]
, 2006 Asynchronous implementation techniques, which measure logic delays at run time and activate registers accordingly, are inherently more robust than their synchronous counterparts, which estimate worst-case delays at design time, and constrain the clock ...

Discrete Mathematics, 1974 AbstractA possible way to obtain a complicated graph imbedding in a surface is to derive it as a covering of a simpler imbedding by assigning “voltages” to the edges of the simpler imbedding. Although this new method is but the dual of the current graph construction,it has independent importance in practical applications, illustrated here by a ...

The boundaries of dipole graphs and the complete bipartite graphs K_{2,n}
, 2013 We study the Seifert surfaces of a link by relating the embeddings of graphs by using induced graphs. As applications, we prove that every link $L$ is the boundary of an oriented surface which is obtained from a graph embedding of a complete bipartite ...

Conservation laws and open systems on higher-dimensional networks [PDF]
, 2008 We discuss a framework for defining physical open systems on higher-dimensional complexes. We start with the formalization of the dynamics of open electrical circuits and the Kirchhoff behavior of the underlying open graph or 1-complex.
