This paper employs a 3D hp self-adaptive grid-refinement finite element strategy for the solution of a particular electromagnetic waveguide structure known as Magic-T. This structure is utilized as a power divider/combiner in communication systems as well as in other applications. It often incorporates dielectrics, metallic screws, round corners, and so on, which may facilitate its construction...

The objective of this work is to innovatively apply the boundary element method (BEM) as a general modeling strategy deal with complicated reservoir problems, especially those related heterogeneity and fracture systems, which are common challenges encountered in practice engineering. transient flow behaviors reservoirs containing multi-scale heterogeneities enclosed by arbitrarily shaped bounda...

In today’s competitive educational environment, the quality of undergraduate education is ever more recognised as a fundamental factor in gaining competitive advantage. The evaluation and improvement of the quality of undergraduate education in higher education is an important issue of on-going concern. The aim of this article is to focus on an automated management and evaluation system to effi...

the main purpose of this paper is to present a fuzzy multi-criteria decision making (fmadm) model for appropriate location selection of a health center. therefore, we identify sixteen criteria and sub-criteria for selecting a health center location. these criteria and sub-criteria have been obtained from literature reviews and practical interviews. this paper proposes a method which combines th...

. this paper presents the results of an experimental investigation on shear strength enhancement of reinforced concrete deep beams externally reinforced with fiber reinforced polymer (frp) composites. a total of six deep beam specimens of two different classes, as-built (unstrengthened) and retrofitted were tested in the experimental evaluation program. two composite systems namely carbon/epoxy...

A semi-analytical solution for the simulation of one-dimensional subsurface solute transport incorporating multiple nonequilibrium processes is presented. The solution is based on the theory Ž . w developed by Brusseau et al. 1992 Brusseau, M.L., Jessup, R.E., Rao, P.S.C., 1992. Modeling solute transport influenced by multiprocess nonequilibrium and transformation reactions. Water Ž . x Resourc...

block-flexure is the most common mode of toppling failure in natural and excavated rock slopes. in such failure, some rock blocks break due to tensile stresses and some overturn under their own weights and then all of them topple together. in this paper, first, a brief review of previous studies on toppling failures is presented. then, the physical and mechanical properties of experimental mode...
