This paper is a survey of the transmission techniques used in digital television (TV) standards worldwide. With the increase in the demand for High-Definition (HD) TV, videoon-demand and mobile TV services, there was a real need for more bandwidth-efficient, flawless and crisp video quality, which m[r]
Problem 7-113 A cable of length L is suspended between two points a distance d apart and at the same elevation. If the minimum tension in the cable is T min , determine the total weight of the cable and the maximum tension devel[r]
In this paper, the effects of wind velocity according to height above the ground on the rain-wind induced vibration (RWIV) of stay cables are investigated. RWIV of the cable is modeled using the linear theory of cable vibration and the central difference algorithm. The wind speed profile according t[r]
Cable Winches Vertical pulls require care when lowering cable so that the cable does not start paying off the reel too fast and falling out of control. A reel brake can help provide added tension. For lifting cables, a cable winch often is employed (see Figure[r]
