This paper deals with the singularly perturbed boundary value problem for a linear second order differential-difference equation of convection-diffusion type. In the numerical treatment of such type of problems, first we use Taylor’s approximation

In this paper, a time dependent singularly perturbed differential-difference convection-diffusion equation is solved numerically by using an adaptive grid method. Similar boundary value problems arise in computational neuroscience in determination of

Inconel 718 samples were printed with varying scan speed and laser power with volume energy density (VED) in the range of 52 J/mm3 to 75 J/mm3. Samples were then subjected to solution treatment and aging as per standards. Further, samples were charac
