Approximating data with parametric B-splines for computer aided design | This 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-splines | 1985-12 |

Applicative updating and provisional computation in functional programming | Large 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; computers | 1983-06 |

Feature-based reverse engineering of mechanical parts: revision | Reverse engineering of mechanical parts requires extraction of information about an instance of a particular part sufficient to replicate the part using appropriate manufacturing techniques. This is important in a wide variety of situations, since functional CAD models are often unavailable or unusa... | 1995-11-06 | |

Analysis of Functional Programs using Attribute Grammars | An 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.

Extraction of Micro-Terrain Features | Micro-terrain features are topographic structures relavent to the behavior of a simulation, but with a horizontal extent significantly less than the resolution of the base-level terrain data covering the area in which these structures occur. Thus, these features are not directly extractable from ele... | 1998-08 | |

Parametric approximation to surfaces | The use of B-splines for the approximation of functions and data is well established. Issues such as parametrization, knot placement and reparametrizaton are important in determining the B-spline representation for the data.
