The transmission capacity and quality of transmitted image still an important parameters for the most hiding techniques in digital image transmission in private communication systems. In this paper we propose modification of spatial-domain hiding method for (Color/Gray) in (color) images hiding. In this method, the cover image (CI) is partitioned into number of squares blocks of equal sizes (m x m)...
This paper presents a dynamic absorber to reduce the torsional vibrations exhibited during start-up of systems driven by synchronous motors. The dynamic absorber is comprised of two inertia rings connected, via spring-like material, to both the driver side (motor) and the driven side (compressor). The stiffness and inertia properties of the absorber are optimally tuned to match the torsional natural...
