Carter, John B. | Evaluating the potential of programmable multiprocessor cache controllers | The next generation of scalable parallel systems (e.g., machines by KSR, Convex, and others) will have shared memory supported in hardware, unlike most current generation machines (e.g., offerings by Intel, nCube, and Thinking Machines). However, current shared memory architectures are constrained b... | Programmable multiprocessor cache controllers; Scalable parallel systems; Shared memory | 1994 |

Hansen, Charles D. | Fast stereoscopic images with ray-traced volume rendering | One of the drawbacks of standard volume rendering techniques is that it is often difficult to comprehend the three-dimensional structure of the volume from a single frame; this is especially true in cases where there is no solid surface. Generally, several frames must be generated and viewed sequent... | Volume rendering; Ray tracing; Stereoscopic images; Reprojection | 1994 |

Parker, Steven G.; Johnson, Christopher R. | Interactive manipulation of contour data using the layers program | The "layers" program is useful for visualizing and editing large sets of contour data.

Stringfellow, Gerald B.; Sadwick, Laurence P. | Low pressure pyrolysis of alternate phosphorus precursors for chemical beam epitaxial growth of InP and related compounds | The most widely used phosphorous source in chemical beam epitaxy (CBE) is phosphine (PH3). However, because it is highly toxic, alternatives to phosphine have been sought for the growth of phosphorous-containing compounds. We have investigated the pyrolysis rates and reaction products, in low pres... | Chemical Beam Epitaxy; CBE | 1994 |

Bruderlin, Beat | Moving into higher dimensions of geometric constraint solving | In this paper, we present an approach to geometric constraint solving, based on degree of freedom analysis. Any geometric primitive (point, line, circle, plane, etc.) possesses an intrinsic degree of freedom in its embedding space which is usually two or three dimensional. Constraints reduce the deg... | Geometric constraint solving | 1994 |

Hansen, Charles D. | Parallel volume rendering using binary-swap compositing | Existing volume rendering methods, though capable of very effective visualizations, are computationally intensive and therefore fail to achieve interactive rendering rates for large data sets. Although computing technology continues to advance, computer processing power never seems to catch up to th... | 1994 | |

Freire, Juliana | Parallelizing tabled evaluations | SLG is a table-oriented resolution method that extends SLD evaluation in two ways. It computes the well-founded model for logic programs with negation with polynomial data complexity,and it terminates for programs with the bounded-term-size property.
