Fastbus is a standard parallel bus system for high speed and/or large-scale data acquisition and processing. It is built up from back-plane segments housed in crates, linked together by cable segments for intercrate communication. Each segment supports multiprocessors, and independent segment operation permits a high degree of parallelism. Handshake bus protocols that are uniform over the system ensure reliability, and both high and low speed devices can be accomodated. A synchronous mode provides for data block transfers at maximum speed. The fundamental structure of Fastbus and details of its basic operations are presented.

A four-stage model of the execution of dataflow graphs, the processing structure model, is presented. Each stage has its own responsibility and offers a well-defined interface to other stages. The processing structure model presents a framework for understanding, analyzing and supporting the execution of dataflow programs in a distributed system. The distributed aspects of the processing affect one or two of the four stages depending on how the stages are arranged. The model has been simulated and experimentation has been done concerning the assignment of dataflow nodes (i.e. tasks) to computer systems. Initial results from the experimentation are presented.

This paper present a discussion of design issues for interactive user interfaces. Aspects such as the user's model, command languages, input-output devices, the information display and user's requirements are surveyed. Emphasis is placed on new hardware and software technology that reduces the number of procedures that a user must remember and do in order to use a system effectively. Some aspects related to user interface evaluation are also discussed.

A PET microcomputer is used to acquire data from a Reticon (a photodiode array) at the rate of 45.45 kHz in each diode scan. The mechanism is discussed in detail. An automatic spectral calibration procedure is described for a Jarrell-Ash (model 78–460) spectrometer. An in-depth semiquantitative discussion about improving the signal-to-noise ratio is also presented.

Would it be appropriate to consider the application of an expert system in your particular problem domain? What are the major components of expert systems and what is their range of applicability? Do they have unique capabilities and, if so, why are they so different from traditional software systems? Are development and implementation methods for expert systems non-standard? What drawbacks, advantages and limitations can be exposed? Where have they come from and where are they going? In this paper an attempt is made to throw light on the above and other relevant matters pertaining to expert systems.

A simply constructed interface for real-time instrument control and data acquisition has been developed that operates independently, allowing time-shared use of a laboratory minicomputer. Although primarily intended for automatic control of a Du Pont 650B electron spectrometer, the interface design is sufficiently general that it can be used in a number of applications.
