The research deals with profit maximization of a Textile Industry by Linear Programming (LP). Linear Programming, an operation research technique is widely used in finding solutions to complex managerial decision problems. ...

In this thesis, the fundamental concepts of nanofluids and literature survey have been discussed, and two-dimensional time-dependent natural convection flow and heat transfer inside the semi-circular enclosure charged by ...

The usage of mathematical models of physical systems are increasing day by day in various disciplines of science and engineering for simulation, optimization, or control. Descriptor systems is a special kind of formation ...

Viscous incompressible fluid in a steady two-dimensional natural convection flow considering viscous dissipation along a uniformly heated vertical wavy surface in presence of internal heat absorption and variable viscosity ...

In this study, we seek to apply a system of nonlinear ordinary differential equa- tions to analyze how the dynamics of primary infection affect the proliferation of Diphtheria. We prove existence, uniqueness, positivity, ...

Natural ventilation is an effective system to reduce the consumption of energy required to condition buildings and to improve the quality of indoor air. Buildings will construct such a way that can use natural energy more ...

In this research, a numerical analysis has been carried out on combined convection in a lid driven trapezoidal enclosure with sinusoidal wavy bottom surface filled with hybrid nanofluid composed of equal quantities of Cu ...

Magnetohydrodynamic mixed convection fluid flow and heat transfer in a partially heated rectangular enclosure with elliptic block has been investigated numerically in this study. The left wall of the enclosure has been ...

Free convection of Magnetohydrodynamic (MHD) fluidin a cavity with a heated cone has been investigated in this work. It is carried out in two parts. First, only the MHD fluid is considered. Secondly, nanoparticles are ...

In this thesis, a large scale linear programming problem consisting several parameters such as labor cost, raw material cost, machine and other cost have been formulated. Then the formulated problem has been solved by using ...
