The paper reports on specific work carried out using the initial graphics exchange specification (IGES) for data transfer between two proprietary minicomputer-based and microcomputer-based computer-aided design (CAD) systems. The purpose of this work was to pinpoint and highlight the problems that may, and can, arise through performing detailed reflection, transmission and closed-loop tests using ... View full abstract»

Electrical utilities constitute both an essential service and a very large business sector, with annual billings in excess of Pounds 11 billion in the UK alone. The article reviews the computers applications that are being installed to operate the vast geographically spread networks in a safe and efficient manner. Network operations seem to be an ideal candidate for an integrated information syste... View full abstract»

This paper introduces a new class of CAE analysis tool-electronic breadboarding. Electronic breadboarding is an extension to simulation with a much higher level of interactivity and with a focus on finding design problems, not just predicting results. A comparison of electronic breadboarding to traditional breadboard testing shows the pros and cons of both and synergy in using the two together to ... View full abstract»

Describes a method by which manufacturing constraints can be incorporated into the detailed design stage of a part through using CADCAM software. The method has been implemented in a software package which brings certain manufacturing constraints to the attention of a detail designer as a part is created on a CADCAM screen. By making the designer aware of these constraints, the part being designed... View full abstract»

A prototype system is described which characterises engineering graphics in a limited domain. This approach uses production rules to facilitate the use of pattern matching for part features and discernment between features. By emphasising feature recognition, an independence from the rules of orthographic projection is attained. This flexibility enables the system to handle additional part represe... View full abstract»
