Mathews, V. John | Adaptive unsharp masking for contrast enhancement | ABSTRACT A new scheme o,f unsharp masking for image contrast enhancement is presented in this paper. An adaptive algorithm is introduced so that a sharpening action is performed only in locations where the image exhibits significant dynamics. Hence, the amplification of noise in smooth areas i... | | 1997 |

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 |

Horch, Kenneth W. | Are the extrinsic muscles better suited for signaling joint angles or finger tip location? | We used a biomechanical model of the human long finger to determine whether the extrinsic muscles are better suited for estimating the finger's joint angles or for estimating location of the finger tip. We found that two of the extrinsic muscles together could provide information sufficient to direc... | Extrinsic muscles; Metacarpophalangeal joint; Biomechanical models | 1997 |

Weinstein, David | Cache-rings for memory efficient isosurface construction | Processor speeds continue to increase at faster rates than memory speeds. As this performance gap widens, it becomes increasingly important to develop "memory-conscious" algorithms - programs that still optimize instruction count and algorithmic complexity, but that also integrate optimizations for ... | Processor speeds; Memory speeds; Computer memory; Cache-rings | 1997 |

Freire, Juliana | Combining scheduling strategies in tabled evaluations | Tabled evaluations ensure termination for Datalog programs by distinguishing calls to tabled subgoals. Given several variant subgoals in an evaluation, only the first (the generator) will use program clause resolution, the rest (consumers) must perform answer resolution using answers computed by th... | SLG; SLG-WAM; Tabling; Local scheduling; Batched scheduling | 1997 |

Stringfellow, Gerald B. | Compositional modulation and ordering in semiconductors | The science of materials as a specific discipline is a relatively modern development. Within this rather modern field, the study of semiconductor materials is an even more recent development. Modern textbooks on materials science focus primarily on the properties of metals and second on the properti... | Materials scientists; Controlled ordering | 1997 |

Parker, Steven G.; Hansen, Charles D.; Johnson, Christopher R. | Computational steering and the SCIRun integrated problem solving environment | SCIRun is a problem solving environment that allows the interactive construction, debugging, and steering of large-scale scientific computations. We review related systems and introduce a taxonomy that explores different computational steering solutions. Considering these approaches, we discuss why ... | Computational steering; Problem solving environment; SCIRun; Volume rendering | 1997 |

Furse, Cynthia M.; Gandhi, Om P. | Computations of SAR distributions for two anatomically-based models of the human head using CAD files of commercial telephones and the parallelized FDTD code | The Finite Difference Time Domain (FDTD) method is well suited for the computation of bio-electromagnetic effects and has become the method of choice for most researchers in this area. There does however remain some limitations on its use. Firstly the FDTD method requires large amounts of memory and... | Finite-difference time-domain method; FDTD; SAR distributions; CAD files | 1997 |

Riloff, Ellen M. | Corpus-based approach for building semantic lexicons | Semantic knowledge can be a great asset to natural language processing systems, but it is usually hand-coded for each application. Although some semantic information is available in general-purpose knowledge bases such as Word Net and Cyc, many applications require domain-specific lexicons that repr... | Corpus-based method; Semantic lexicons | 1997 |
