Recording single cells from alert rats currently requires a cable to connect brain electrodes to the acquisition system. If no cable were necessary, a variety of interesting experiments would become possible, and the design of other experiments would be simplified. To eliminate the need for a cable we have developed a one-channel radiotelemetry system that is easily carried by a rat. This syste...

This paper analyzes inter-firm alliances for providing the home computer user with an innovative new telecommunications service: a high-speed connection to the Internet. After providing an overview of the Internet access provider industry, it discusses the split of competencies needed to deliver this new service, between monopolistic infrastructure (cable and local telephone) companies and entr...

The paper presents a Special Protection Scheme solution for the central Zagreb transmission system. The Central Zagreb transmission system is characterized by a highly meshed network with combined overhead and cable sections and a special operation of the 110 kV cable link between two power plants important for the city’s heat and electricity supply. The Special Protection Scheme is developed u...

The development of Smart Grid, Digital Substation concepts, is characterized by the complication of protection and automation systems, which requires the development and implementation of new algorithms of work. In this article there considered a new approach to the organization of automatic reclosing of high-voltage overhead-cable power lines transmissions in metropolitan areas, based on the r...

Partial discharge (PD) events happen inside the power cables and cable terminations with the insulation degradation. The PD detection can effectively supply the information of cable status. According to the electrical and electromagnetic emission of PD activities, high-frequency transformer (HFCT) and ultrahigh-frequency (UHF) methods are employed to detect the PD signals. Besides, a portable P...

The wiring of buildings is an emotive subject. Hitherto the unchallenge domain of PVC, the status quo is under threat from many directions. Change is in the air and from all points of view the questions are daunting. PVC is by far the largest wire and cable segment (in Europe 700 kta of compound) and building wire is approximately 50% of this volume. Industrial power cables (e.g. 1 kv) is the s...

The cable television industry evolved from make-shift configurations of antennae and wires serving fewer than one hundred customers in 1950, to an industry serving 50 million subscribers and generating revenues of almost $18 billion by 1990 [30, 31]. Although entrepreneurial ingenuity and technological innovation provided the foundation for this extraordinary growth, the Federal Communications ...

workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎however, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...
