An approach is presented for the solution of the discrete conveyor model for service time distributions which are general but bounded and where there is no storage at work stations and no recirculation. The model is described by states with the Markovian property and solutions may be derived for...

This paper is a review of the use of contextual information in statistical image analysis. After defining what we mean by 'context', we describe the Bayesian approach to high-level image analysis using deformable templates. We describe important aspects of work on character recognition and...

Orthodox trade theory rests on a number of unrealistic assumptions which include, among others, constant returns to scale in production and perfect competition in product and factor markets. This has led many commentators to express strong skepticism about the policy conclusions flowing from the...

The paper re-examines the issue of the appropriate unit for measuring output in cost utility analysis and the technique that will measure it. There are two main themes. The first is that utility, as it is often conceived and quantified, is not an appropriate basis for measurement. Consequently,...
