Stoller, Leigh B. | Message passing support in the Avalanche widget | Minimizing communication latency in message passing multiprocessing systems is critical. An emerging problem in these systems is the latency contribution costs caused by the need to percolate the message through the memory hierarchy (at both sending and receiving nodes) and the additional cost of ma... | Avalanche widget; Message passing; Cache coherence; Message copying; Cache miss rates; Computer memory | 1996 |

Lindstrom, Gary E. | Migrating relational data to an OODB: strategies and lessions from a molecular biology experience | The growing maturity of OODB technology is causing many enterprises to consider migrating relational databases to OODBs. While data remapping is relatively straightforward, greater challenges lie in economically and non-invasively adapting legacy application software. We report on a genetics labora... | OODB; Relational data; Data migration | 1997 |

Fujimoto, Richard M. | Optimal performance of distributed simulation programs | This paper describes a technique to analyze the potential speedup of distributed simulation programs. A distributed simulation strategy is proposed which minimizes execution time through the use of an oracle to control the simulation. Because the strategy relies on an oracle, it cannot be used for ... | Distributed simulation programs | 1987 |

Davis, Al | An introduction to asynchronous circuit design | The purpose of this monograph is to provide both an introduction to field of asynchronous digital circuit design and an overview of the practical state of the art in 1997. In the early days of digital circuit design, little distinction was made between synchronous and asynchronous circuits. However,... | Asynchronous circuit design | 1997 |

Keller, Robert M. | Denotational models for parallel programs with indeterminate operators | Several approaches to networks of concurrently-operating modules involving indeterminacy are discussed. Techniques for representing the denotational semantics of such networks, and for verifying properties of them, are presented, including an oracle approach, an axiomatic approach, a data-type reduc... | Denotational models; Indeterminate operators | 1977 |

Breaderson, Dean J. | The I3Stick: an inexpensive, immersive, interaction device | Virtual environments require interaction devices that are intuitive and ergonomic, yet capable of many input parameters. Many devices satisfying these requirements can be expensive, difficult to manipulate, and often require the integration of large software libraries with existing applications. We ... | Virtual environments; I3Stick; Interaction devices | 1999 |

Mathew, Binu K.; Davis, Al; Fang, Zhen | A Gaussian probability accelerator for SPHINX 3 | Accurate real-time speech recognition is not currently possible in the mobile embedded space where the need for natural voice interfaces is clearly important. The continuous nature of speech recognition coupled with an inherently large working set creates significant cache interference with other... | Speech recognition; SPHINX 3; Speech recognizers | 2003-07-22 |

Hansen, Charles D. | Reconstruction and visualization of planetary nebulae | Abstract-From our terrestrially confined viewpoint, the actual three-dimensional shape of distant astronomical objects is, in general, very challenging to determine. For one class of astronomical objects, however, spatial structure can be recovered from conventional 2D images alone. So-called planet... | | 2005-09 |

Hansen, Charles D. | Proxy chain method and its application to scientific visualization | We present a method for combining multiple point-based constraints in haptic programming environments. Instead of using a single proxy point for haptic feedback, the method maintains a separate proxy for each constraint. The reaction force is computed by linking the proxies in a chain. Constraints a... | | 2006 |

Pickett, Forrest B. | Simulation of Cells | A self-timed cell set and library for the design of integrated circuits is presented. The cell set and library are two different cellular methods of designing integrated circuits. These have been incorporated to form a hybrid system which exploits the advantages provided by each. The cell set an... | Self-timed; Cell set | 1984 |

Bhanu, Bir | Segmentation of complex outdoor scenes | A new simpler approach to image segmentation via recursive region splitting and merging is presented. Unlike other techniques the kernel of splitting is based on a generalization of a two class gradient relaxation method and merging uses a statistical analysis of variance. | Image segmentation; Outdoor scenes; Recursive region splitting; Segmentation algorithm | 1985 |
