The influence of physical damping on the numerical stability of time integration analysis is an open question since decades ago. In this paper, it is shown that, under specific very general conditions, physical damping can be disregarded when studying the numerical stability. It is also shown that, provided the specific conditions are met, analysis of structural systems involved in extremely hi...

The methods to solve the stochastic MINLP problems fall into two categories: numerical integration method and sample average method. The numerical integration method utilizes numerical integration techniques to calculate the multi-dimensional integrals, such as the Gaussian Quadratures/Cubatures method. The Monte Carlo simulation is one of the most widely used sample average methods. Acevedo an...

in this paper operational matrix of bernstein polynomials (bps) is used to solve bratu equation. this nonlinear equation appears in the particular elecotrospun nanofibers fabrication process framework. elecotrospun organic nanofibers have been used for a large variety of filtration applications such as in non-woven and filtration industries. by using operational matrix of fractional integration...
