Observability Analysis Using Extended Incidence Matrix
2010 Asia-Pacific Power and Energy Engineering Conference, 2010Power system state estimator uses the set of available measurements such as voltage and power in order to estimate the system state. Given a set of measurements and their locations, the network observability analysis will determine if a unique estimation can be found for the system state.

ABSTRACT Adopted for use in Shell Expro in 1989, the Incident Potential Matrix is a tool used to assess an incident in terms of ‘what might have happened’, the initial assessment being made by the immediate line supervisor and the appropriate category of ‘potential’ entered on the Incident Report Form. This may be reviewed and confirmed,

Matrix Rational Completions Satisfying Generalized Incidence Equations
Canadian Journal of Mathematics, 1965Let us consider the following problem. Let there be v elements x1 , . . . , xv and v sets S1, . . . , Sv such that every set contains exactly k distinct elements and every pair of sets has exactly λ distinct elements in common. To avoid trivial situations we shall in general assume that 0 < λ < k < v — 1.

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.

Link Prediction by Incidence Matrix Factorization
2016Link prediction suffers from the data sparsity problem. This paper presents and validates our hypothesis that, for sparse networks, incidence matrix factorization (IMF) could perform better than adjacency matrix factorization (AMF), which has been used in many previous studies.

Incidence matrix approach for calculating readiness levels
Journal of Systems Science and Systems Engineering, 2014Contemporary system maturity assessment approaches have failed to provide robust quantitative system evaluations resulting in increased program costs and developmental risks. Standard assessment metrics, such as Technology Readiness Levels (TRL), do not sufficiently evaluate increasingly complex systems.

Tree Enumeration from the Incidence Matrix
International Journal of Electrical Engineering & Education, 1987Cyclic tree generation via the outer product of vectors in determinant evaluation by Grassmann's algebra yields an algorithm for symbolic circuit analysis with a particularly simple test applicable to the enumeration of symbolic terms in both numerator and denominator of transfer functions of active circuits.

Matrix projective spaces and twistorlike incidence structures
Journal of Mathematical Physics, 2009We consider projective spaces constructed over (real or complex) matrix rings and study their topological separation properties. The method of construction results in non-Hausdorff spaces, where incidence properties associated with a Grassmann/flag interpretation of the spaces are neatly encoded in the lack of standard topological separation properties.

On the Generalized Inverse of an Incidence Matrix
Journal of the Society for Industrial and Applied Mathematics, 1965Abstract : The properties of the generalized inverse of an arbitrary incidence matrix are examined in connection with the properties of the corresponding directed graph. (Author)
