AbstractPurpose -The purpose of this paper is to introduce a new methodology to implement periodic and anti-periodic boundary conditions in the element free Galerkin method (EFGM). Design/methodology/approach -This paper makes use of the interpolating moving least squares (IMLS) in the EFGM to implement periodic and anti-periodic boundary conditions. This fact allows imposing periodic and anti-periodic boundary conditions in a way similar to the one used by the finite element method. Findings -EFGM generally uses the moving least squares to obtain its shape functions. So, these functions do not possess the Kronecker delta property. As a consequence, the imposition of essential, as well as periodic and anti-periodic boundary conditions needs other techniques to do it. When EFGM makes use of IMLS the shape functions satisfy the Kronecker delta property. As consequence the periodic boundary conditions implementation can be done in a direct way, similar to the FEM. Originality/value -IMLS provides a new way of periodic boundary conditions implementation in EFGM. This kind of implementation provides an easy and direct way in comparison to usual existing methods. With this technique EFGM can now easily take advantage of electrical machines symmetry.
The meshless element-free Galerkin method (EFGM) is used to solve partial differential equations responsible for obtaining the electromagnetic fields generated by a transmission line. For this purpose, a 2D model based in a real transmission line is constructed and simulated. The results obtained by EFGM have good accuracy and they are compared against analytical solution and Finite Element Method in order to verify the effectiveness, advantages and disadvantages of the method.
This work applies the linear optimization theory to the minimum cost flow problem of voice traffic management in a real mobile telecommunication network. A voice traffic assignment method between core network elements is proposed to achieve the optimum trade-off between cost and transmission capacity in graph routes. In this sense, the Simplex Method is aplied to perform flow optimization and verify the optimal traffic distribution among network nodes. Finally, results for different costs scales are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
