    The effect of measurement errors on the performance of the pattern classifier is studied. It is shown that measurement errors affect the optimality of the decision rule, and can result in higher classification error probability. The results derived in the paper are applied to the problem of quality control of gas meters. It is shown that, to maintain the same quality level of lots of 300 meters, t... View full abstract»

  • Method for reducing memory conflicts caused by busy waiting in multiple processor synchronisation

    Publication Year: 1980, Page(s):85 - 87

    To implement synchronisation by process switching for multiple processors, more basic synchronisation means are needed which delay a process by busy waiting. This busy waiting may cause severe memory conflicts as a side effect. A considerable reduction of these memory conflicts can be acheived by testing a lock variable only at those instants when there is a fair chance of finding it unlocked. An ... View full abstract»

  • Sampled multiserver queues with general arrivals and deterministic service time

    Publication Year: 1980, Page(s):88 - 92

    Queues which arise in certain computer applications and in synchronous communication on a limited number of channels can often be modelled as sampled queues. Sampled G/D/c queues are considered, and simple bounds on the average waiting time are derived when the sampling interval is equal to, and half of, the service time. The asymptotic behaviour of these bounds and comparison with available numer... View full abstract»

  • Synthesis procedure for ¿-symmetric boolean functions

    Publication Year: 1980, Page(s):93 - 96
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (345 KB)

    A synthesis procedure for the ¿-symmetric Boolean function is presented. The blocks of variables corresponding to the partition of the ¿-symmetry are first mapped into new sets of variables. The function itself is then synthesised from these new variables. The procedure is systematic and leads to circuit realisations with smaller depths. The procedure is illustrated by examples.

  • Khar: a translator system for machine-oriented languages

    Publication Year: 1980

    The paper describes a highly portable translator system for machine-oriented languages, allowing the development of m. o. l. s for microprocessors and the ability to provide native compilers for these languages on small development or evalutaion systems. View full abstract»
