The NIST RoboCrane is a cable-suspended robot with the potential to reduce the disadvantages of conventional cranes. One weakness of the RoboCrane is the need for at least three fixed rigid support points for the six overhead cable connections. In many potential applications, these rigid support points are simply not available. This article presents a new RoboCrane support concept based on rigi...

Cable theory was introduced for neurons by Wilfrid Rall more than half a century ago, and is widely used today for modeling the voltage and current flow in neuronal and dendritic structures. This theory was derived assuming that the extracellular medium is either inexistent, or modeled as a resistor. For modeling neurons in more realistic situations, where the extracellular medium has more comp...

High voltage XLPE power cable is a very important part of power system. The degree of electric-tree aging in the cable can be estimated effectually by measuring partial discharge. An on-line partial discharge monitor system of XLPE power cable was developed based on the virtual instrument designing conception. This system has the advantage of wide analog bandwidth, excellent anti-interference a...

The Federal Communications Commission (FCC) initiated a proceeding in 2002 to examine whether and to what extent cable operators should be limited in the number of subscribers they can serve. This paper reports on the performance of experimental (laboratory) markets designed to be similar in structure and practice to the market where cable operators negotiate affiliate fees with various program...

(1) and c is the speed of light in vacuum. Estimate the time-average power P (i.e., the radiation) that escapes from the end of the cable using vector (or scalar) Huygens-Kirchhoff diffraction theory for the case that the cable is excited with a TEM wave with λ b. Compare the cases of a coaxial cable by itself, and one with its outer conductor attached to a ground plane such that the radiation ...

This research examines how the South Korean cable television industry has developed. The research reviews a brief history of the South Korean broadcast television system and examines the U.S. cable television system to provide better understanding of the development of the South Korean cable television. The research explains policies, laws, industrial structure, and three issues of localism, co...

This paper presents empirical results of cable noise reduction techniques as demonstrated in a TEM cell operating with radiated fields from 2 200 MHz. It is the second part of a two-paper series. The first paper discussed cable types and shield connections. In this second paper, the effects of load and source resistances and chassis connections are examined. For each topic, well established the...

We demonstrate the successful transmission of Data Over Cable Service Interface Specification (DOCSIS) signals in the 600 MHz and 5.5 GHz frequency bands. Both signals are generated simultaneously using an optical harmonic up-conversion of the DOCSIS signal provided by a cable modem termination system (CMTS). The optical signal is transmitted over 10 km SSMF. After photo-detection, the wireline...

The FCC is now engaged in resolving whether to require cable system operators who provide cable modem service to residential users to furnish cable transmission capacity to unaffiliated Internet Service Providers. To resolve this controversy, the FCC has expressed a desire " to develop an analytical approach that is, to the extent possible, consistent across multiple platforms. " This comment m...

Today’s undersea cable systems are increasingly complex and part of a much larger network topology that spans the continents. Operational efficiency can be significantly enhanced by integrating the undersea paths seamlessly into the overall network architecture. This implies that it is desirable to have one control plane for both the terrestrial and undersea parts of the network, one network ma...
