    Computer-based fraud is an increasing crime with only one in twenty frauds resulting in a successful prosecution. In order to make systems secure the use of the public key cipher (PKC) system is being introduced. PKC has the advantage that the secret aspect of the process is wholly under the control of the person receiving the information. The use of PKC with a digital signature is discussed.< View full abstract»

    For many years TV broadcasting and private mobile radio (PMR) have been fighting over radio frequencies that both considered vital for their development. The VHF Band III has been given to the broadcasters and PMR services alternately and is now owned by PMR ser,vices. However the Government is considering reinstituting TV broadcasting in the VHF bands. The author discusses how mobile communicatio... View full abstract»

    The Docklands Light Railway, which opened in August 1987, is the first railway specifically designed for distributed-microprocessor control. The capability of light-rail vehicles to run around tight curves is fully exploited as is their ability to climb steep gradients. At present there are 11 vehicles, nine are in service and two are on standby. The operation of the railway depends on two automat... View full abstract»

    Designers of large structures such as oil rigs cannot afford to build a succession of prototypes so they use computers to analyse the structure. However, this takes time and this kind of computer can be very expensive. The author discusses the use of parallel processing, in particular the Inmos T800 transputer. This kind of processor is very powerful, fast and flexible and is also affordable.< View full abstract»

    Neural network computing uses the structure of neurons in the brain as a model for parallel-processing computers. There are numerous models which differ in detail but share common features including: the training of networks; simple computational elements with large numbers of interconnections; interconnection strengths are real-valued analogue quantities; and the network forms internal representa...
