Low-Observability Distribution System State Estimation by Graph Computing with Enhanced Numerical Stability

open access: yesEng
In distribution systems, limited measurement configurations and communication constraints often result in a low success rate of data acquisition, posing challenges to both system observability and the real-time performance required by state estimation ...

Factors in random graphs

open access: yesRandom Structures & Algorithms, 2008
AbstractLet H be a fixed graph on v vertices. For an n‐vertex graph G with n divisible by v, an H‐factor of G is a collection of n/v copies of H whose vertex sets partition V (G).In this work, we consider the threshold thH(n) of the property that an Erdős‐Rényi random graph (on n points) contains an H‐factor.

Factorizations of regular graphs

open access: yesJournal of Combinatorial Theory, Series B, 1992
Let G be a k-regular graph of order 2n such that \(k\geq n\). \textit{A. J. W. Hilton} [J. Graph Theory 9, 193-196 (1985; Zbl 0624.05050)] proved that G contains at least \(\lfloor k/3\rfloor\) edge-disjoint 1-factors. Hilton's theorem is improved in this paper that G contains at least \(\lfloor k/2\rfloor\) edge-disjoint 1-factors.
