The systems of linear algebraic equations have an important role in the field of science and engineering. This modification has been developed by using the procedure of Gauss-Seidel method and the concept of substitution techniques. Developed modification of Gauss-Seidel method is a fast convergent as compared to Gauss Jacobi’s method, Gauss-Seidel method and successive over-relaxation (SOR) method. It works on the diagonally dominant as well as positive definite symmetric systems of linear algebraic equations. Its solution has been compared with the Gauss Jacobi’s method, Gauss-Seidel method and Successive over-Relaxation method by taking different systems of linear algebraic equations and found that, it was reducing to the number of iterations and errors in each problem.</p>2024-01-10T00:00:00+00:00Copyright (c) 2024 Babylonian Journal of Mathematicshttps://mesopotamian.press/journals/index.php/BJM/article/view/512On commutativity of alternative rings with [xy^n x±yx^n y,x]=0 2024-09-10T16:48:14+00:00Abubakar Salisu abubakarsalisu8989@gmail.comShu’aibu Salisu abubakarsalisu8989@gmail.comMustapha Mannir Gafai abubakarsalisu8989@gmail.com<p>Let R be a n-torsion free with identity 1 ,In this article we investigate and prove the commutativity of alternative ring of the property(p_1 ), (p_2) and(p_3 ) under suitable constraints.</p> <p> (p_1 ) [xy^n x±yx^n y,x]=0</p> <p> (p_2 ) [xy^n x±yx^n y,y]=0 </p> <p> (p_3) [x(〖xy)〗^2+(〖xy)〗^2 x,x] = 0. ∀ x,y ∈R.</p> <p> </p>2024-05-21T00:00:00+00:00Copyright (c) 2024 Babylonian Journal of Mathematicshttps://mesopotamian.press/journals/index.php/BJM/article/view/451Some Results on Commutativity for Alternative Rings With 2, 3-Torsion Free.2024-07-17T07:36:11+00:00Abubakar Salisuabubakarsalisu@fedpolydaura.edu.ngMustapha Mannir Gafai abubakarsalisu8989@gmail.comShu’aibu Salisu ssalisu94@gmail.com<p><strong>ABSTRACT</strong></p> <p>In this article, we establish and proof some theorem on commutativity of alternative ring with 2, 3 –torsion free satisfy the following properties (Identities): </p> <p> (P<sub>1</sub>) [x<sup>2</sup>y<sup>2</sup>+y<sup>2</sup>x<sup>2</sup>,x]=0</p> <p>(p<sub>2</sub>) [x(xy)<sup>2</sup>+(xy)<sup>2</sup>x,x]=0</p> <p>(p<sub>3</sub>) [x(x<sup>2</sup>y<sup>2</sup>),x]=0</p> <p>(p<sub>4</sub>) [x(xy),x]=0 for every x,y in R.</p> <p><strong>Keywords: </strong>.</p>2024-03-25T00:00:00+00:00Copyright (c) 2024 Babylonian Journal of Mathematicshttps://mesopotamian.press/journals/index.php/BJM/article/view/280A Survey of MCDM-Based Software Engineering Method2024-02-07T20:15:23+00:00sahar Mohammedyousifsahar4@uoanbar.edu.iqAbdulrahman Kareem Oleiwiyousifsahar4@uoanbar.edu.iqThaaer kh.Asmanyousifsahar4@uoanbar.edu.iqHadeel M Salehyousifsahar4@uoanbar.edu.iqAlaa Mohammad Mahmoodyousifsahar4@uoanbar.edu.iqIsa AVCIyousifsahar4@uoanbar.edu.iq<p>Multi-criteria decision making (MCDM) is an operation research subfield (OR). Decision-making is primarily a process involving various actors, including individuals, groups of individuals, institutions, and the state. As a discipline, multi-criteria decision-making is relatively new Many researchers have devoted their time to developing new MCDM models and techniques since the 1950s and 1960s, when the foundations of modern multi-criteria decision-making methods were laid. Research and development in the area have intensified recently and appear to be developing tremendously. Few attempts have been made to systematically convey the theoretical foundations and advancements of multi-criteria decision-making systems, despite the widespread and intense development. The framework for evaluating judgments and the methodological options are still up for debate. In this paper reviews of MCDM/MADM technologies will be included describing their scenarios. Making a decision that is more appropriate than others to solve a particular problem is the goal of decision-making (DM), so this study presents a review of the advantages and disadvantages of different decision-making techniques, specifically in the field of software engineering.</p>2024-02-18T00:00:00+00:00Copyright (c) 2024 Babylonian Journal of Mathematicshttps://mesopotamian.press/journals/index.php/BJM/article/view/245UTLIZATION OF GENERALIZED HEAT FLUX MODEL ON THERMAL TRANSPORT OF POWELL-EYRING MODEL VIA OHAM WITH HEAT GENEARTION ASPECTS2024-01-26T07:29:59+00:00Esha Rafiqueesharafique77@gmail.comNida Ilyasnidaalyas8887@gmail.comMuhammad Sohailmuhammad_sohail111@yahoo.com<p>The focus of this work is on the flow of a spinning Powell-Eyring nanofluid in the boundary layer in three dimensions using magnetohydrodynamics (MHD). The research simulates mass transfer processes and heat transfer processes using non-Fick's mass flux theory and non-Fourier heat flux theory, respectively. Heat transport phenomena are analyzed by the integration of non-linear heat generation/absorption and thermal radiation properties. The boundary layer method is employed to solve a system of nonlinear partial differential equations (PDE) in the mathematical formulation. These equations are converted into nonlinear ordinary differential equations (ODES), and then the optimal OHAM with convergence control parameters is used to solve them. The impact of various physical movement circumstances on concentration and temperature profiles is visually represented through the generation of diagrams. This study provides important new understandings for both applied and scholarly research on complex heat transfer and fluid dynamics mechanisms in the context of three-dimensional MHD boundary layer flows of rotating Powell-Eyring nanofluids.</p>2024-02-20T00:00:00+00:00Copyright (c) 2024 Babylonian Journal of Mathematicshttps://mesopotamian.press/journals/index.php/BJM/article/view/507Restricted visible submodules and fully restricted visible module 2024-09-03T18:45:19+00:00Mahmood S.

Khantufailmarwat@uetpeshawar.edu.pk<p>In this paper, we present modified variational iteration algorithm-I for the numerical solution of Burger's equations. In this recently developed technique, an auxiliary parameter is introduced which speed up the convergence rate of the series solutions. The suggested technique gives approximate and exact solutions with easily computable terms to linear and nonlinear PDEs without the Adomian polynomials, small perturbation, discretization or linearization.<br>In order to assess the precision, reliability and compactness, results of the proposed procedure are compared with the variational iteration method, which reveals that the MVIA-I exceptionally productive, computationally attractive and has more accuracy than the others methods. Two numerical test problems are given to judge the behaviour of the modified algorithms and absolute errors are used to evaluate the accuracy of the method. Numerical results are carried out for different values of the parameters.</p>2024-03-25T00:00:00+00:00Copyright (c) 2024 Babylonian Journal of Mathematics
