36 Analysis of Functional Programs using Attribute GrammarsAn attribute grammar combines the standard context-free grammar that defines the syntax of a programming language with attributes that define semantic aspects of the language. This information makes attribute grammars very useful for performing the semantic analysis of programs. Functional programmi...programming languages, functional programs; attributed grammar1985-08
37 Applicative updating and provisional computation in functional programmingLarge scale computing systems often consist of calculations which are repeated for many sets of input data. If the variance between the data sets is small, there may be portions of the computation which are not affected by the changes in the input values. The effort required for such systems can be ...recomputation; efficient recomputation; function graphs; computers1983-06
38 Approximating data with parametric B-splines for computer aided designThis thesis addresses some of the difficulties that can be encountered when approximation is used as a design tool. In many cases, it is most intuitive for a designer to specify points on or near a desired contour, and approximate them with a curve. Merely computing some approximation to a set of da...computer graphics; computer-aided design; approximation theory; B-splines1985-12
