We set up a discrete space-time dynamical model of molecules with thermalised kinetic energy and repulsive cores, in an external potential. The model obeys the first and second laws of thermodynamics. The continuum limit, obtained using a MAPLE program, gives rise to coupled reaction-diffusion equations for the density and temperature fields. The system obeys Onsager symmetry and exhibits the S...

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 ...

Abstract In the present work a model of evolution composition transition zone between material and pre-applied coating under conditions intense short-term thermal impulse is proposed. The pulse times are assumed to be comparable relaxation heat mass fluxes. This led need account for finite rates propagation in model, leading hyperbolic transfer equations. phenomena thermodiffusion (Soret effect...

In many flow phenomenons of fluid with medium molecular weight, the energy flux is effected due to inhomogeneity concentration mass. This contribution considered as diffusion-thermo effect or Dufour effect. this research article addressed for magnetohydrodynamics (MHD) Jeffrey’s fractional past an exponentially accelerated vertical plate generalized thermal and mass transports through a porous ...
