Sobh, Tarek M.; Henderson, Thomas C. | Prototyping environment for robot manipulators | Prototyping is an important activity in engineering. Prototype development is a good test for checking the viability of a proposed system. Prototypes can also help in determining system parameters, ranges, or in designing better systems. We are proposing a prototyping environment for electro-mechani... | Prototyping; Robot manipulators | 1993 |

Lindstrom, Gary E. | ETYMA: a framework for modular systems | Modularity, i.e. support for the flexible construction, adaptation, and combination of units of software, is an important goal in many systems. In most cases, however, systems achieve only a few aspects of modularity. The problem can be traced to the inflexibility, or the limited view of modularity ... | ETYMA; Modularity; Modular systems | 1994 |

Kessler, Robert R. | Persistence is hard, then you die! or compiler and runtime support for a persistent common Lisp. | Integrating persistence into an existing programming language is a serious undertaking. Preserving the essence of t h e existing language, adequately supporting persistence, and maintaining efficiency require low-level support from the compiler and runtime systems. Pervasive, low-level changes were ... | Persistence; Programming language; Lisp compiler; Persistent Lisp | 1994 |

Bruderlin, Beat | An interactive N-Dimensional constraint system | In this paper, we present a graph-based approach to geometric constraint solving. Geometric primitives (points, lines, circles, planes, etc.) possess intrinsic degrees of freedom in their embedding space. Constraints reduce the degrees of freedom of a set of objects. A constraint graph is created wi... | Geometric constraint solving | 1994 |

Sutherland, Karen T. | The stability of geometric inference in location determination | Geometric inference is widely used in computer vision, but very little attention has been given to the question of how geometric properties affect the resulting errors in the inferences made.
