The trend towards higher performance mechanical systems has naturally led to the need to design such systems in an optimal fashion. Lighter components and higher operating speeds both demand a level of design a step above that provided conventionally. This paper describes a research effort aimed at developing the methodology for such system design. The methodology is based on accurate computer ...

In this paper we specify five abstract algorithms for the parallel execution of production systems on the DAD0 machine. Each algorithm is designed to capture the inherent parallelism in a variety of different production system programs. Ongoing research aims to substantiate our conclusions by empirically evaluating the performance of each algorithm on the DAD02 prototype, presently under constr...

This paper examines two facial composite systems that present multiple faces during construction to more closely resemble natural face processing. We evaluated a ‘parallel’ version of PRO-fit, which presents facial features in sets of six or twelve, and EvoFIT, a system in development, that contains a holistic face model and an evolutionary interface. The PRO-fit parallel interface turned out n...

Abs&oct--To improve the performance of forward chaining production systems, a new parallel execution model is proposed, where multiple production rules are Bred in parallel in each production cycle. This paper provides solutions for three major problems in parallel rule firing. The interference analysis, which detects cases where a parallel firing result is different from the result of any sequ...

Let A and B be two groups of up to n elements distributed on the rst row of an n n reconng-urable mesh, and CA;B a subset of the cartesian product A B satisfying some unknown condition C. Only one broadcasting step is needed in order to compute CA;B's elements. However, the problem of moving CA;B's elements to the rst row in optimal time (so that they can be further processed) is not trivial. T...
