This paper investigates the influence of suction on flow, heat and mass transfer characteristics over a permeable shrinking sheet immersed in doubly stratified micropolar fluid. The model which consists partial differential equations is converted into set nonlinear using similarity transformations then solved bvp4c solver. Numerical results obtained are presented graphically for distributions v...

The effects of thermal and velocity slip on Newtonian fluid steady boundary layer stagnation-point flow heat transfer through a porous shrinking sheet with suction effect are investigated in the present research. By using similarity transformation, partial differential equation (PDE) is converted to an ordinary (ODE) solved shooting technique get numerical results. characteristics for various v...

Magnetohydrodynamics (MHD) stagnation point flow in a porous medium with velocity slip is investigated this study. The governing system of partial differential equations transformed into set non-linear ordinary by using the similarity transformation. Subsequently, are numerically solved shooting method MAPLE software. skin friction coefficient and local Nusselt number obtained presented graphic...

Sequence compression is one of the most promising tools for strengthening pseudo-random generators used in stream ciphers. Indeed, adding compression components can thwart algebraic attacks aimed at LFSR-based stream ciphers. Among such components are the Shrinking Generator and the Self-Shrinking Generator, as well as recent variations on Bit-Search-based decimation. We propose a general model...

kinetics of the chemical leaching of chalcocite from a low-grade copper ore in a ferric sulfate medium was investigated using the constrained least square optimization technique. the experiments were carried out for different particle sizes in both the reactor and column at constant eh, ph, and temperature. the leaching rate increased with increase in the temperature. about 50% of the cu recove...
