Chemically reacting Magnetohydrodynamics (MHD) boundary layer flow of heat and mass transfer past a low-heat-resistant sheet moving vertically downwards

  A theoretical study has been conducted to investigate the steady Magnetohydrodynamics (MHD) boundary layer flow past a low-heat-resistant sheet moving vertically downwards. The fluid is considered viscous, incompressible and electrically conducting. The non-linear coupled differential equations are solved numerically by applying Runge-Kutta integration scheme coupled with Newton-Raphson shooting technique....

The dual exponential mapping on dual rotations

  Dual numbers are introduced by Clifford in the mid-nineteenth century and they are  systematically applied to  kinematics by Study (1903) and Kotelnikov (1895). Any point  on  the dual unit sphere (DUS) corresponds to a straight line in  QUOTE  (real three space), and vice versa. By this way, there is a one to one correspondence between the dual curves on DUS and the one...
