Purpose: Mesh technique is the standard for inguinal hernia repair because of less recurrence,   but it is inferior or equal to sutured technique in case of other post-operative complications   such as chronic pain. This clinical trial set out to compare these two techniques.   Materials and Methods: A total number of 322 cases of unilateral inguinal hernia in participants   older than 18 yea...

We propose an efficient mesh-less method for functional integral equations. Its convergence analysis has been provided. It is tested via a few numerical experiments which show the efficiency and applicability of the proposed method. Attractive numerical results have been obtained.

method previously employed by westoo for the determination of alkylmercury compounds was producing very wide picks during g.c. analyses. changing the column temperature, carrier gas flow and pressure did not supersede the problem. therefore change in packing materials was experienced. 5% dc-200 on gas-chrom did not work. a packing material used for chlorinated hydrocarbons w, 80-100 mesh. as th...

A new hybrid mesh generation method is proposed and applied to generate mesh for three-dimensional solids with open-ended tubular holes. Regions around the tubular holes are represented by hexahedral elements, and tetrahedral elements tessellate the rest of the domain. The procedure consists of three steps. Firstly, surfaces of tubular holes are recognized and discretized, and then the hexahedr...

a fundamental topic in computational fluid dynamics is the role of coordinate particularly for searching optimized coordinates. the objective of this study is the numerical modeling of supersonic flows using a new coordinate system i.e. unified coordinate system (ucs) uses moving mesh with motionless viewing window technique. ucs has an advantage over traditional coordinate systems (eulerian an...

Coupled two-dimensional (2D) morphodynamic and bank erosion models are gaining attentions in recent years. It has been shown that such models have advantages over the one-dimensional (1D) modeling approaches. In this paper, a previous 2D bank erosion model with the moving mesh method is extended to include the fixed mesh approach. Further, two practical streams with differing complexity are sim...

in this study, focuses on applying the hp-version for forward modeling. the eit forward solver is normally based on the conventional finite element method (hfem). in h-fem, the polynomial order p of the element shape functions is constant and the element size h, is decreased. to accurately simulate the forward solution with the hfem, a mesh with large number of nodes and elements is usually need...

An adaptive mesh refinement (AMR) method based on discretization matrix metric is described. The computational algorithm is implemented using OpenFOAM parallel library. This open C++ library provides data structures and routines to work with the finite volume method and adaptive mesh. The method was used for oil flow in final drive simulation. For more efficient use of computing resources, we d...
