Network Connectivity Identification Method based on Incidence Matrix and Branch Pointer Vector
2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2019Network connectivity identification is an important issue of topology analysis. Regarding how to identify the connected components in large-scale power systems, a new network connectivity identification method based on incidence matrix and branch pointer

Mutual incidence matrix of two balanced incomplete block designs
Journal of Combinatorial DesignsWe propose to consider a mutual incidence matrix $M$ of two balanced incomplete block designs built on the same finite set. In the simplest case, this matrix reduces to the standard incidence matrix of one block design.

An optimal planning model of the sectional switch and tie line for the distribution network is proposed considering the tradeoff between the system reliability and economy. First, the fault incidence matrices are established for the distribution network,

Generators of matrix incidence algebras [PDF]
Australas. J Comb., 2000 Let \(n\in\mathbb{N}\) and let \(K\) be a field. Let \(\leq\) be a partial order on \(\{1,2, \dots, n\}\). The paper contains a main theorem: Let \(A_n (\preceq)\) be the matrix incidence algebra consisting of those \(n\times n\) matrices \(A=(a_{i,j})\) with entries in \(K\), satisfying \(a_{i,j}=0\) whenever \(i\leq j\).

On the incidence matrix of a graph
IEEE Transactions on Circuits and Systems, 1976We give some new results on the rank of the incidence matrix of a graph when calculations are done over the real numbers and in the Boolean algebra with two elements.

DETERMINANT OF INCIDENCE MATRIX OF NIL-ALGEBRA
Communications of the Korean Mathematical Society, 2002Summary: The incidence matrices corresponding to a nil-algebra of finite index \(n\) can be used to determine the nilpotency. We find the smallest positive integer \(m\) such that the sum of the incidence matrices \(\sum_P \langle n,m \rangle^P\) is invertible.
