The following monograph deals with the approximate stochastic behavior of a system consisting of a sequence of servers in series with finite storage between consecutive servers. The methods employ deterministic queueing and diffusion approximations w

We are concerned here with a service facility consisting of a large (- finite) number of servers in parallel. The service times for all servers are identical, but there is a preferential ordering of the servers. Each newly arriving customer enters th

A comparison is made between the rolling horizon strategy of traffic signal control at an isolated intersection and the strategy of switching the signal when a queue vanishes. It is shown that the former strategy has some undesirable consequences.

The assessment of the merits of a colour television system in fulfilling the principle of constant luminance must take into account the errors that can result from the use of a vestigial-sideband emission with envelope detection. Comparison is made b

Measurements of the visibility of small-magnitude luminance perturbations at various parts of the grey scale have been made using television displays. The purpose was to establish whether the measurements made by many workers using optical apparatus

The paper describes an investigation into three similar methods of reducing the bandwidth required for the transmission of television pictures. The three methods all involve the isolation of the essential brightness changes in the picture; these are
