Abstract: The reliable transmission of information over noisy channels is one of the basic requirements of digital information and communication systems. Because of this requirement, modern communication systems rely heavily on powerful channel coding methodologies. Channel coding is often used in digital communication systems to protect the digital information from noise and interference and reduce the number of bit errors. In digital television the video and audio information is digitized and compressed using the Moving Picture Experts Group (MPEG) compression standard.

Abstract:The motion of a blind traveler in an unfamiliar environment is somewhat similar to that of a mobile robot. Both have the physical ability to perform the motion, but are dependent on a sensory system to detect obstacles in the

Abstract: Stress analysis using Finite Element Analysis for maxillary central incisor, mandibular central incisor and mandibular first molar human teeth were carried out in this work. AutoCAD (2007) program used to drawing two dimensional model of each tooth and then convert this two dimensional to three dimensional model. This Auto CAD structural model was imported to finite element software ANSYS (V. 10) program to get finite element model. 200N compression vertical loading was applied at two incisal points with different inclination.
