摘要:

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, the test sample set size had to be increased from 100 to 160 meters.

摘要:

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 effort in this direction was made in the C. mmp design. Certain deficiencies of that approach, mainly related to its use of the interrupt mechanism, are avoided in a new approach which is based on an ‘eavesdropping’ state of the processor. The astonishingly simple solution only requires minor extensions of present-day processor designs.

摘要:

Queues which arise in certain computer applications and in synchronous communication on a limited number of channels can often be modelled as sampled queues. SampledG/D/cqueues 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 numerical results for the sampledM/D/ccase indicate that they are reasonably tight for moderate and largec.

摘要:

A synthesis procedure for the ρ-symmetric Boolean function is presented. The blocks of variables corresponding to the partition of the ρ-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.

摘要:

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.
