Abstract : Ubiquitous high-speed communication is desirable, may be even essential for acceptable quality of life, productivity of business and so on. According to this demand, Power-Line Communication (PLC) arises in this field as a feasible broadband connection. The backbone of this system is of course the PLC modem which its design is a challenging task, as it covers several layers of the Open System Interconnection (OSI) standard.
Abstract : Zygapophyseal joints (or facet joints), are a plane synovial joint which located between the articular facet processes of the vertebral arch. These joints are considered freely movable; the degree of possible motion varies according to the individual structural design and facet planes. Ten dried vertebrae were used for each cervical, thoracic and lumbar regions (220 vertebrae). AutoCAD program finds measurement for the surface area, the curvature, and the angle of the facet processes in each region for the vertebral column.
Abstract : Today and after a lot of research had been concentrated to employing the electrical bioimpedance property to extract many related physiological events. one of these directed research had introduced a very amazing technology of measuring the cardiac output with features have never been seen elsewhere in any traditional CO measuring techniques, the powerful of this new technique comes from it is being non-invasive ,clinically satisfied precision, easy to perform, long term applicable, cost effective, portable, risk free, fast CO assessment.
