Anesthetic management of laboring parturients with Arnold-Chiari type I malformation poses a difficult challenge for the anesthesiologist. The increase in intracranial pressure during uterine contractions, coughing, valsalva maneuvers, and expulsion of the fetus can be detrimental to the mother during the process of labor and delivery. No concrete evidence has implicated high cerebral spinal fl...

In this paper, we develop a multigrid preconditioner for the discrete system of linear equations which results from the mixed formulation of the linear plane elasticity problem using the Arnold-Winther elements. This, in turn, can be reduced to the problem of finding a multigrid preconditioner for the form (·, ·)+(div ·,div ·) in the symmetric tensor space resulting from Arnold-Winther elements...

Image Steganography is the art of hiding the secret data into a cover image. The proposed method presents a steganographic method which is based on DWT-Arnold method, where DWT is used to convert the cover image into frequency domain and Arnold method is used for encoding the QR code of secret message. The quality of the image can be maintained by preserving the low frequency coefficients since...

The wake of two oscillating cylinders in a tandem arrangement is a nonlinear system that displays Arnold tongues. We show by numerical simulations that their geometry depends on the phase difference theta between the two oscillating cylinders. At theta = 0 there may be holes inside these intraresonance regions unlike the solid Arnold tongues encountered in single-cylinder oscillations. This imp...
