    The Northern Line of the London Underground boasts one of the world's longest railway tunnels, upwards of 50 stations, 170 train units and typically carries over 700000 passenger-journeys per day. A major disruption in the service-a suspected fire, or a passenger falling ill-can bring the line to a halt for up to an hour, and it can take many hours thereafter to restore normal timetables. Comprehe... View full abstract»

    The author describes how, this year, the Aegean island of Agios Efstratios will begin installing a field demonstration of a combined wind-turbine/diesel generating system. The author outlines this generating system and shows how the problem of energy storage requirements (to cover short-term fluctuations in wind speed) has been overcome by the adoption of a flywheel system.<> View full abstract»

    It is a peculiarity of electrical and electromagnetic equipment that it is capable of interfering with the operation of other such equipment at a distance. This mysterious property of electromagnetic radiation, which underlies radio and all its related technologies, needs to be carefully controlled if radio, telecommunications, electrical and electronic equipment is to coexist safely. Such control... View full abstract»

    The availability of cheap optical fibre and associated transceivers has encouraged the development of the next generation of computer networks. Most prominent among these is the fibre distributed-date interface (FDDI), which is expected to become a standard. The authors describe the principal advantages of the FDDI (namely its size and transmission rate) and outline the apparently bright future of... View full abstract»
