Hamming index of graphs with respect to its incidence matrix

open access: yesIndonesian Journal of Combinatorics, 2022
Let B(G) be the incidence matrix of a graph G. The row in B(G)corresponding to a vertex v, denoted by s(v) is the string which belongs to ℤm2, a set of m-tuples over a field of order two.

Formation of Moments Influence Matrix in Frame Based on Graph of its Design Scheme [PDF]

open access: yesMATEC 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 ...

Can Defect Prediction Be Useful for Coarse-Level Tasks of Software Testing?

open access: yesApplied Sciences, 2020
It is popular to use software defect prediction (SDP) techniques to predict bugs in software in the past 20 years. Before conducting software testing (ST), the result of SDP assists on resource allocation for ST.

On some regular and singular problems of Birkhoff interpolation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
Here we investigate the pure (0,1,…,r−2,r)-interpolation problem on the zeros of (1−x2)Pn(α)(x)=(1−x2)Pn(α,α)(x), α>−1, where Pn(α,α)(x) is the Jacobi polynomial of degree n with β=α.
