Abstract: The purpose of this paper is to present a simplified model of inductively coupled plasma (ICP). The study of the effect of parameters such as current and number of turns in the coil is simulated using Comsol Multiphysics 3.5 by applying the fluid dynamic models that are generally appropriate for the investigation of inductively coupled plasmas.

Abstract: With advance of high speed computer networks, multimedia, transmission technology, an amount of information is being communicated in digital form .Numerous watermarking techniques have been developed to protect images with high security performance. For the proposed method, shifting is applied for embedding stage, add to that our contribution in this method involved the threshold concept to improve the visual quality, embedding capacity, data loss of the host image. The performance of the proposed watermarking schemes have been evaluated by using the watermarked images of size 512×512(standard images) and also applied (medical images), and the watermark (payload) is of the same size as the host image. Simulation results demonstrate that the proposed algorithm generates high performances in the visual quality, PSNR,SSIM between original image and watermarked image, and the hiding capacity compared to the previous works.
