Planetary nebula axial ratios have been used to investigate the intrinsic structures of sources having elliptical or circular morphologies, using methods previously applied to elliptical galaxies. The results appear to indicate that most such nebulae have intrinsic axial ratios β in the range 0.92→0.75, and that gradients of surface brightness with axial ratio are most consistent with oblate sh...

Nonmagnetostrictive CoFeSiB alloy wires were subjected to cold drawing processing followed by annealing under tension, in order to induce the formation of circular magnetic anisotropy. The axial (M Z – HZ) and circular (M f – Hf) hysteresis loops indicate the existence of induced transverse anisotropy, with the magnitude of the anisotropy field being dependent on the processing conditions, whil...

Superhydrophobicity can arise from the ability of a submerged rough hydrophobic surface to trap air in its surface pores, and thereby reduce the contact area between the water and the frictional solid walls. A submerged surface can only remain superhydrophobic (SHP) as long as it retains the air in its pores. SHP surfaces have a short underwater life, and their longevity depends strongly on the...

This research work is focused on the nonlinear modeling and control of a hydrostatic thrust bearing. In proposed work, mathematical model formulated for bearing system that includes effects uncertainties, unmodelled dynamics, nonlinearities. Depending type inputs, divided into three subsystems. Each subsystem has same output, i.e., fluid film thickness with different types input, viscosity, sup...
