Abstract :

This paper develops a solution procedure of Neutrosophic Optimization (NSO) to solve optimum welded beam design with inexact co-efficient and resources. Interval approximation method is used here to convert the imprecise co-efficient which is a triangular neutrosophic number to an interval number. We transform this interval number to a parametric interval valued functional form and then solve this parametric problem by NSO technique. Usually interval valued optimization consist of two level mathematical programs, but a parametric interval valued optimization in neutrosophic environment is direct approach to find the objective function, this is the main advantage. In this paper we have considered a welded beam design with cost of welding as objective and the maximum shear stress in the weld group, maximum bending stress in the beam, buckling load of the beam and deflection at the tip of a welded steel beam as constraints .Numerical example is given here to illustrate this structural model through this approximation method.

Abstract :

This paper investigates multi–objective Neutrosophic Optimization (NSO) approach to optimize the cost of welding and deflection at the tip of a welded steel beam, while the maximum shear stress in the weld group, maximum bending stress in the beam, and buckling load of the beam have been considered as constraints. The problem of designing an optimal welded beam consists of dimensioning a welded steel beam and the welding length so as to minimize its cost, subject to the constraints as stated above. The purpose of the present study firstly to investigate the effect of truth, indeterminacy and falsity membership function in neutrosophic optimization in perspective of welded beam design and secondly is to analyse the results obtained by different optimization methods like fuzzy, intuitionistic fuzzy so that the welding cost of the welded steel beam become most cost effective with minimum deflection. Specifically based on truth, indeterminacy and falsity membership function, a multi objective NSO algorithm has been developed to optimize the welding cost, subjected to a set of constraints. It has been shown that NSO is an efficient method in finding out the optimum value in comparison to other iterative methods for nonlinear welded beam design in imprecise environment till investigated. Numerical example is also given to demonstrate the efficiency of the proposed NSO approach.

Abstract :

In this paper we introduce a new class of closed maps namely **gs-closed maps which settled in between the class of *gs-closed maps18 and the class of gs-closed maps8. We also introduce and study new class of homeomorphisms called **gs-homeomorphisms and **gs*-homeomorphisms. Further we show that the set of all **gs*-homeomorphisms form a group under the operation composition of maps.

A Study of Magnetohydrodynamic Flow of Conducting Walter’s Visco-Elastic Fluid in a Long Uniform Rectangular Channel

Abstract :

The aim of the present paper is to study the magneto hydrodynamic flow of conducting Walter’s visco-elastic fluid in a long uniform straight channel of rectangular cross-section under the influence of time varying pressure gradient and uniform magnetic field applied perpendicularly to the flow of fluid. The exact solution for the velocity of fluid has been obtained by using integral transform technique. Some particular cases of pressure gradient have been discussed in detail. Also we have discussed the case when magnetic field is withdrawn. Besides, the corresponding viscous flow problem has been derived as a limiting case when the relaxation time parameter tends to become zero.

Abstract :

An accurate edge dominating set D of a graph G = (V,E) is an accurate connected edge dominating set, if < D > is connected. The accurate connected edge domination number (G) cae  is the minimum cardinality of an accurate connected edge dominating set. In this paper, we initiate a study of (G) cae  in terms of vertices, edges, cut vertices and different parameters of G . Further we characterize the accurate connected edge domination number in cartesian product and corona of graphs.
