Evaluating Popular Statistical Properties of Incomplete Block Designs: A MATLAB Program Approach
Mathematics, 2021 Evaluating the statistical properties of a semi-Latin square, and in general, an incomplete block design, is vital in determining the usefulness of the design for experimentation.

Incidence hypergraphs: Injectivity, uniformity, and matrix-tree theorems [PDF]
Linear Algebra and its Applications, 2022 An oriented hypergraph is an oriented incidence structure that allows for the generalization of graph theoretic concepts to integer matrices through its locally signed graphic substructure. The locally graphic behaviors are formalized in the subobject classifier of incidence hypergraphs.

Asymptotics for Incidence Matrix Classes [PDF]
The Electronic Journal of Combinatorics, 2006 We define incidence matrices to be zero-one matrices with no zero rows or columns. We are interested in counting incidence matrices with a given number of ones, irrespective of the number of rows or columns. A classification of incidence matrices is considered for which conditions of symmetry by transposition, having no repeated rows/columns, or ...

The singular value decomposition method of improved incidence matrix for isomorphism identification of epicyclic gear trains [PDF]
Mechanical Sciences, 2022 The epicyclic gear train (EGT) is an advanced gear transmission mechanism, which is widely applied in drive systems. It is of great significance to eliminate the same structure in the type synthesis of EGTs.

Reliability assessment of island multi‐energy microgrids
Energy Conversion and Economics, 2021 Multi‐energy microgrids could result in more flexibility and increase reliability by interconnecting networks. Electricity and gas networks exhibit very different dynamic behaviours in response to a fault or failure.

, 1997 We consider the two-person zero-sum game in which the strategy sets for Players I and II consist of the vertices and the edges of a directed graph respectively. If Player I chooses vertex v and Player II chooses edge e, then the payoff is zero if v and e are not incident and otherwise it is 1 or -1 according as e originates or terminates at v.

Formation of Moments Influence Matrix in Frame Based on Graph of its Design Scheme [PDF]
MATEC Web of Conferences, 2021 A procedure is proposed for the automated construction of the bending moments influence matrix in the frame based on the graph of its discrete model. Forming the incidence matrix of the graph characterizing the topological structure of the design scheme ...
