The determinant of the distance matrix of graphs with blocks at most bicyclic
(Elsevier Science Inc., 2021-04-01)
Let G be a connected graph on n vertices and D(G) be its distance matrix. The formula for computing the determinant of this matrix in terms of the number of vertices is known when the graph is either a tree or a unicyclic ...

Evaluation of the particle geometry and interphase influence on the filler-matrix debonding process
(IOP Publishing, 2019-06-14)
Incorporation of rigid fillers into polymer matrices represents a widely used technique to obtain improved performance. The mechanical behavior finally obtained is closely related to a wide range of involved factors (filler ...
Improved bounds for the inverses of diagonally dominant tridiagonal matrices
(Elsevier Science Inc, 2018-08)
We obtain new bounds for the entries of the inverse of a diagonally-dominant tridiagonal matrix which improve the best previous ones, due to H.-B. Li et al. We apply our bounds to the tridiagonal matrices arising in the ...
A Comparison Study on Criteria to Select the Most Adequate Weighting Matrix
(Universidad Nacional de Salta. Facultad de Ciencias Económicas, Jurídicas y Sociales. Instituto de Estudios Laborales y del Desarrollo Económico, 2017-06)
The practice of spatial econometrics revolves around a weighting matrix, which is often supplied by the user on previous knowledge. This is the so called W issue and, probably, the aprioristic approach is not the best ...
