    The purpose of the work described was to explore the utility of the Smalltalk/V object-oriented language in prototyping an application that would form just one module of a potentially much more extensive and complex system, a complete VLSI design system. The author also wanted to investigate issues arising from the fact that the application itself and the development methodology would have to anti... View full abstract»

    It is frequently necessary to machine a contour which has been defined by discreet co-ordinate information. Traditionally, this had been achieved by contour-fitting procedures such as mathematical, parametric or B-splines. A technique has been established for fitting circular arcs to such data to give smooth curves. This article describes how that technique may be used on a PC to generate numerica...

  • Structured knowledge engineering: a Yourdon-based approach to the analysis and design of KBS

    Publication Year: 1991, Page(s):61 - 68

    The tasks of analysing and designing knowledge-based systems (KBS) are put into a structured framework. In order to do this, a structured lifecycle for knowledge-based systems is introduced, as well as some tools that allow both the taking of a structured approach and the production of appropriate structured models of the knowledge domain. The authors look first at the process of KBS design to com... View full abstract»

    Reports on the design and implementation of a computer-aided sheet nesting system (CASNS) for the nesting of two-dimensional irregular-shaped sheet-metal blanks on a given sheet stock or coil stock. The system is designed by considering several constraints of sheet-metal stamping operations, such as bridge width and grain orientation, and design requirements such as maximising the strength of the ...
