It is proposed to install an underwater observing system off the coast of Seattle, Washington and Vancouver, British Columbia in order to allow long-term scientific study of the ocean. The area to be covered corresponds to the Juan de Fuca tectonic plate. Electric power will be provided via a cable similar to a submarine telecommunications cable, and communications will be via fiber optics in t...

The KM3NeT EU-funded consortium, pursuing a cubic kilometre scale neutrino telescope in the Mediterranean Sea, is developing technical solutions for the construction of this challenging project, to be realized several kilometres below the sea level. In this framework a proposed DC/DC power system has been designed, maximizing reliability and minimizing difficulties and expensive underwater acti...

This paper examines the advantages and disadvantages of cable cars in public transport within urban areas. The advantages of cable car transport compared to other modes of transport are its quiet operation with an environmentally-acceptable electric drive and the possibility of transporting passengers above the ground, which can provide additional transport dimensions within urban centers. Howe...

the load transfer mechanisms of cable bolts differ from those for normal rebar bolts. the cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. the tendon strength can be evaluated by the tensi...

Controlling the electric field distribution in HVDC cable accessories requires a tight knowledge of properties, particularly electrical conductivity insulating materials constituting system.

Residential or occupational exposures to electric or magnetic fields have been reported to be associated with health problems, particularly cancer and reproductive mishaps. Misconceptions about these alleged effects continue to be published in the medical and scientific literature. Invalid statements relating to these effects are challenged in this paper. Case reports and studies dealing with e...

Impulse over-voltages are very common phenomena in electric power systems. Switching impulses are created by switching surges or local faults while lightning impulses are due to lightning strikes to overhead lines. Both impulses can travel as waves in the system, damaging insulation components and equipment. This paper shows that there may well be a reduction in electric field strength of the i...
