Seafloor observation system using the underwater telecommunication cable is one of the most reliable ways to secure high-speed data transmission and continuous power feeding to underwater devices. In this paper a new scientific submarine cable system will be presented that were proposed by the technical committee organized by IEEE OES (Institute of Electrical and Electronics Engineers, Oceanic ...

The purpose of this paper is to analyze the case of the U.S. Pivot and to suggest an appropriate model including entry strategies and success factors for QPS of Cable TV. The telecommunication companies have been operating QPS including IPTV service, which enables them to cross over broadcasting areas. Due to this circumstance, the Cable TV operators are now concerned and are planning to add QP...

A finite element solution based on equevalent elements is proposed for the static and dynamic analysis of tallhigh tensioned cable antennas. To reduce high number of degrees of freedom in space frame body of a structure, a simple equivalent beam element is defined for each simulative substructure. This numerical procedure is applicable to analyze complex three dimensional assemblies of substruc...

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...

Telecommunication networks have evolved over time as a result of technological advances, and network topologies and equipment have become increasingly complex. Expert systems are being successfully applied to the management of telecommunication networks. However, applying expert systems to network design is another especially beneficial yet still not very common approach. In this paper we propo...

Telecommunication networks have evolved in time thanks to the advances produced by the new technologies and especially, Internet. Expert systems are being applied in management of telecommunication networks because of the necessity of satisfying the demands of the several services of telecommunication. Expert systems applied to their design are an especially interesting and currently little-use...

Traditionally telemetering systems are based on telephone and similar voice-grade channels. Today new channels such as radio or distribution line carrier (DLC) open new possibilities. The most discussed telecommunication channel is the data highway. It is formed by the combination of cable and of optical fibre networks. In many countries the utilities themselves are involved in the development ...
