Opis:
Red Tech. BD, an online based business company intended to spread their business over whole Rajshahi District. As there is no cost for manufacturing the only factor that can maximize the profit is the product transportation cost. Determination of the optimum & reliable transportation medium was the first challenge. A suitable destination for distributing the products in the selected location has been chosen carefully on the basis of demand & minimum rent of warehouse. First, the mathematical model has been formed & then it has been solved by a program written in ‘C’ programming language. The program can show the result of the optimum amount of supply with the corresponding destination together in a single output. Verification of the program or ‘code’ has been done with the help of hand calculation. The company can determine the supply unit with destination to minimize the transportation cost before every shifting of products from warehouse to the destination.

Opis:
An analytical Study of double diffusive MHD flow of a chemically reacting alumina nanofluid past an infinite flat plate is made. Laplace transform method is employed to determine the solution of the governing equation and its analysis showed that increase in both Reynolds number and Prandtl number bring about an increase in the rate of heat transfer coefficient. Skin friction is shown to reduce as the Reynolds number increases. Increase in Reynolds number and Schmidt number, increases the mass transfer coefficient of alumina nanofluid. Generally, comparison is made with other work and an appreciable trend is observed.

Opis:
The solutions of the Schrӧdinger equation with Manning-Rosen plus a class of Yukawa potential (MRCYP) have been presented using the Pekeris-like approximation and parametric Nikiforov-Uvarov (NU) method. The bound state energy eigenvalues and the corresponding un-normalized eigen functions are obtained in terms of Jacobi polynomials. Also, inversely quadratic Yukawa, Yukawa, Manning-Rosen and coulomb potentials have been recovered from the mixed potential and their Eigen values obtained. The Numerical results are computed for some values of n at l = 0 with α = 0.01, 0.1, 2 and 5 using python 3.6 programming, and these results could be applied to molecules moving under the influence of MRYP potential as negative energy eigenvalues obtained indicate a bound state system.
