    Application of Linear Programming on Cost Minimization of Pig Feeds (A Case Study of MOV Farms)
    (Earthline Publisher, India, 2023-07-02) T.O. Aliu; M.G. Gbolagade; A.D. Adeshola
    This paper discusses cost minimization for pig diet formulation. A linear programming model was formulated for minimum cost and maximum shelf life feed quality. Linear programming technique via MATLAB was employed to obtain solution using real life data collected from MOV Farms, Ilorin. The results, attained at the 7 th iteration gave an optimal value of the objective function obtained as #94 , 226 per 100 kg, with the corresponding values 1.5714, 0.6929, 2.8929, 0 and 0 for x 1 (pig weaner), x 2 (pig growers), x 3 (pig finishers), x 4 (pregnant sow), x 5 (lactating sow) recorded respectively. Hence, the cost of pig feeds formulation can be optimized effectively

    J. Nig. Soc. Phys. Sci. 5 (2023) 1368 Journal of the Nigerian Society of Physical Sciences Approximate solution of space fractional order diffusion equations by Gegenbauer collocation and compact finite difference scheme K. Issa∗, A. S. Olorunnisola, T. O. Aliu, A. D. Adeshola Department of Mathematics and Statistics, Kwara State University, Malete, Kwara State, Nigeria. Abstract In this paper, approximation of space fractional order diffusion equation are considered using compact finite difference technique to discretize the time derivative, which was then approximated via shifted Gegenbauer polynomials using zeros of (N − 1) degree shifted Gegenbauer polynomial as collocation points. The important feature in this approach is that it reduces the problems to algebraic linear system of equations together with the boundary conditions gives (N + 1) linear equations. Some theorems are given to establish the convergence and the stability of the proposed method. To validate the efficiency and the accuracy of the method, obtained results are compared with the existing results in the literature. The graphical representation are also displayed for various values of β− Gegenbauer polynomials. It can be observe in the tables of the results and figures that the proposed method performs better than the existing one in the literature

    Numerical investigation of nonlinear radiative flux of non-Newtonian MHD fluid induced by nonlinear driven multi-physical curved mechanism with variable magnetic field
    (Journal of the Nigerian Society of Physical Sciences (JNSPS), 2023) K.M. Sanni; A.D. Adeshola; T.O. Aliu
    This paper discusses two-dimensional heat flow of an incompressible non-Newtonian hydromagnetic fluid over a power-law stretching curved sheet. The energy equation of the flow problem considers a radiative flux influenced by viscous dissipation and surface frictional heating. Lorentz force and Joule heating are taken in the consequence of applied variable magnetic field satisfying solenoidal nature of magnetism. The governing equations are reduced to boundary-layer regime using dimensionless quantities and the resulting PDEs are converted into ODEs by suitable similarity variables. The flow fields; velocity and temperature are computed numerically by implementing Keller-Box shooting method with Jacobi iterative technique. Error analysis is calculated to ensure solutions’ convergence. Interesting flow parameters are examined and plotted graphically. Results show that velocity is increased for large number of fluid rheology and opposite effects are recorded for increasing curvature, Lorentz force, and stretching power. Flow past a flat and curved surfaces are substantial in validation of this present work.
