Spacers in the compact power distribution network are essential components for support, organization, and spacing of conductors. To improve reliability these have an optimized design, it is necessary to evaluate performance variation their geometric parameters. The analysis fundamental, considering that there several models available validated by electric utilities. Due various possible design ...

Climate modeling encompasses an enormous range of spatial and temporal scales. One of its great remaining challenges is bridging the scale gaps between global climate processes, basinscale and regional impacts, and smaller-scale ecosystem dynamics. Improving and accessing enhanced computational resources will help bridge this gap. Nonetheless, enhanced computer power alone is insufficient witho...

In this paper, a class of fourth-order nonlinear elliptic problem is investigated in a bounded convex domain X R. Under some assumptions, the existence and uniqueness of solution are proved via the Schaefer’s Fixed Point Theorem. Furthermore, conforming finite element approximation is applied and H-error estimate and L-error estimate are obtained. Finally, the numerical experiments are provided...

tooth/implant supported fixed prostheses may present biomechanical design problems, as the implant is rigidly anchored within the alveolus, whereas the tooth is attached by the periodontal ligament to the bone allowing movement. many clinicians prefer tooth/implant supported fixed prosthesis designs with rigid connectors. however, there are some doubts about the effect of attachment placement i...

in this paper, the propagation of the waves in the laminated composite plates which is subjected to low velocity impact is investigated using the finite element method. a rigid metallic projectile with spherical nose is considered and the impact of this projectile with laminated composite is studied in this study. considering a finite element model the governing equations of the problem is disc...

We consider the numerical solution of a singularly perturbed two-dimensional reactiondiffusion problem by a multiscale sparse grid finite element method. A Shishkin mesh which resolves the boundary and corner layers, and yields a parameter robust solution, is used. Our analysis shows that the method achieves essentially the same accuracy as the standard Galerkin finite element method, but does ...
