The numerical application of a sequence transformation method proposed in a previous work is considered for the calculation of differential cross-sections corresponding to processes where long range interactions are ...

Punctual Padé approximants are considered as a summation method of the slowly convergent partial wave expansions associated with the scattering by long range potentials. The asymptotic behavior of the family of sequences ...

Previous theorems on the convergence of the [n,n + m] punctual Padé approximants to the scattering amplitude are extended. The new proofs include the cases of nonforward and backward scattering corresponding to potentials ...

In this paper, a three-dimensional numerical solution for the bending study of laminated composite doubly-curved shells is presented. The partial differential equations are solved analytically by the Navier summation for ...

In this article we develop a numerical scheme to deal with interfaces between touching numerical grids when solving the second-order wave equation. We show that it is possible to implement an interface scheme of “penalty” ...

Se ha definido la evaluación como la acción integrada en el proceso formativo, sistemático y continuo, de obtener información sobre el estudiante y la naturaleza y calidad de su aprendizaje, que permite juzgar alternativas ...

Composite columns, partially encased with concrete, present a better structural performance than bare steel columns. The concrete between the flanges, increases the fire resistance of the column, besides the strength and ...
