This report details the sky coverage simulations carried out for the Keck Next Generation Adaptive Optics (NGAO) system. This work was carried out to meet the objectives stated in WBS Element Number: 3.1.2.2.10 Number and Type of Low Order WFS TS. As well as investigating the number of Natural Guide Star (NGS) Shack-Hartmann wavefront sensors (WFS), this report considers the number of modes to ...

To study the natural convection and entropy generation of a semicircular cavity containing heat source under magnetic field, based on single-phase lattice Boltzmann method, closed model with in upper (Case 1) lower 2) is proposed. The filled CuO-H2O nanofluid, hot placed center cavity. effects Rayleigh number, Hartmann number field inclination average Nusselt are studied. results show that incr...

This paper examines the MHD convection slip fluid flow with radiation and heat deposition in a channel in a porous medium. The dimensionless governing equations were solved using the perturbation technique to obtained the analytical expressions of velocity, temperature and concentration profiles of the fluid with expression of Skin friction, mass and heat transfer in terms of Shear stress, Nuss...

The present work deals with the influence of magnetic field on Newtonian fluid sandwiched between two porous cylindrical pipes which are filled micropolar fluids. Fluid motion is occurring along z*-axis and an applied taken in direction perpendicular to motion. On applying appropriate boundary conditions, velocity profiles, microrotations, flow rate, shear stresses obtained for corresponding re...

Do we desire something because it has value? Or is the value of a thing a consequence of the fact that it is desired? To adopt the former alternative is to involve oneself in the task of providing a theory of value which would make value a property things have as it were prior to their serving as objects of desire. Theories of this sort have been developed inter alia by Meinong, Nicolai Hartman...

In this paper, we study the flow of two immiscible fluids namely, couple stress fluid and Jeffrey in a porous channel. Instead classical no-slip conditions on boundaries, used slip boundary conditions, which are more realistic meaningful. addition, inclined magnetic field effects flow. The flowing adjacent to each other region I II, respectively, horizontal nondimensionalized governing equation...

This paper concerns the second law analysis of a viscoelastic fluid over a stretching sheet subject to a transverse magnetic field with heat and mass transfer. The velocity, temperature and concentration profiles are obtained analytically using Kummer’s functions. The effects of the magnetic and viscoelastic parameters on both the longitudianl and the transverse velocities are investigated. The...
