This article investigates the influence of cross-diffusion on the viscous fluid flow over a porous sheet stretching exponentially by applying the convective thermal conditions. Velocity slip at the boundary is considered. The numerical solutions to the governing equations are evaluated using successive linearisation procedure and Chebyshev collocation method. It is observed from this study that...

In cointegrating regressions, available estimators and test statistics are nuisance parameter dependent. This paper addresses this problem as an identi…cation failure. We focus on set estimation of long-run coe¢ cients (denoted ). We check whether and to what degree popular estimation methods, speci…cally the Maximum Likelihood of Johansen (1995), Fully Modi…ed OLS [Phillips and Hansen (1990); ...

In the present analysis, the Dufour and Soret effects on unsteady heat-mass transfer of a viscous incompressible Powell-Eyring fluids flow past an expanding/shrinking permeable sheet are reported. The fluid boundary layer develops over the variable sheet with suction/injection to the non-uniform free stream velocity. Under the symmetry group of transformations, the governing equations along wit...

We study Soret-Dufour and radiation effects on unsteady viscous incompressible MHD flow along semi infinite inclined permeable moving plate with variable temperature and mass diffusion embedded in a porous medium numerically, by taking into account the effect of viscous dissipation. The dimensionless governing equations of flow field are solved numerically by Crank-Nicolson finite difference me...

The present article exploits a novel application of AI-based Levenberg–Marquardt scheme with backpropagated neural network (LMS–BPNN) to analyze the double-diffusive free convection nanofluid flow model (DDFC-NFM) over an inclined plate in existence Brownian motion and thermophoresis properties embedded porous medium. governing PDEs representing DDFC-NFM are transformed into system nonlinear OD...

Abstract Here the assessment of entropy generation with Soret and Dufour impact in flow MHD Prandtl fluid along an unsteady stretching surface has been measured. Nonlinear mixed convection convective conditions for heat/mass transfer are imposed at surface. The outcome viscous dissipation radiation is considered heat features. obtained system nonlinear PDEs converted to ODEs by consuming dimens...

A wide range of tests for heteroskedasticity have been proposed in econometrics and statistics.1 Although a few exact tests are available (e.g. Goldfeld-Quandt’s F -test, its extensions and Szroeter’s procedures),2 common heteroskedasticity tests are asymptotic which may not control size in finite samples. So a number of recent studies have tried to improve the reliability of these tests using ...
