Cable networks have evolved from offering broadcast services to providing high rate two-way data services. In the next step, cable operators intend to use Voice over IP (VoIP) to provide cable telephony services. In a cable network the users are connected to the headend through a cable modem. The headend is responsible for allocating upstream bandwidth to the various cable modems. Each cable mo...

Despite the recent developments in structural health monitoring, there remain great challenges for accurately, conveniently, and economically assessing the in-service performance of the main cables for long-span suspension bridges. A long-term structural health monitoring technique is developed to measure the tension force with a conventional sensing technology and further provide the in-servic...

Before commencing excavation or other work where power or other cables may be buried, it is important to determine the location of cables to ensure that they are not damaged. This paper describes a method of power-cable detection and location that uses measurements of the magnetic field produced by the currents in the cable, and presents the results of tests performed to evaluate the method. Th...

broadband data networks, access networks, network monitoring & management, hybrid fiber coaxial network technology Hybrid fiber-coaxial (HFC) technology is emerging as one of the means of delivering high-speed data services to the home. Cable operators worldwide are deploying HFC networks to enable subscriber accesses to the World Wide Web, to Email, Chat rooms, and other data services at speed...

Temperature cables restrained from lateral movement, were measured as a function of grain height, cable location and surface coating. For the restrained conditions, the cable forces were one to nine times those previously measured for unrestrained cables. The large load increase on the restrained cables is believed to be caused by the flow profile which existed at each of the three different ca...

cables have always been under consideration as a structural element because of important features such as large strength to weight ratios and long spans. their equilibrium analysis is an important issue in this regard. but this analysis involves highly nonlinear equations arising from large deformations and material nonlinearity. different methods have been under use for numerical analysis of s...

Nowadays, shovels play an important role in production of open pit mines and their failures result in significant production loss and considerable increase in maintenance costs. Therefore, reliability and risk analysis can help to improve production, productivity and reduce production costs. In this study, reliability of electric cable shovel of Chadormalu iron ore mine in Iran was investigated...

planning robot trajectory is a complex task that plays a significant role in design and application of robots in task space. the problem is formulated as a trajectory optimization problem which is fundamentally a constrained nonlinear optimization problem. open-loop optimal control method is proposed as an approach for trajectory optimization of cable parallel manipulator for a given two-end-po...

The Trans Bay Cable (TBC) is a ±200-kilovolt (kV), 400 MW 85-km long High Voltage Direct Current (DC) buried transmission line linking Pittsburg, CA with San Francisco, CA (SF) beneath the San Francisco Estuary. The TBC runs parallel to the migratory route of various marine species, including green sturgeon, Chinook salmon, and steelhead trout. In July and August 2014, an extensive series of ma...

Broadband access technologies of DSL and Cable Modem (CM) are now widely deployed by competing telecom and cable TV network operators respectively. Fiber-based FTTP (FTTH, FTTB, etc.) will be the ultimate access solutions. This paper will examine the broadband access network evolution options for FTTP over cable TV’s HFC networks and discuss its competitiveness when compared with telecom networ...
