    Some of the arguments that have been given both for and against the use of natural languages in question-answering and programming systems are discussed. Several natural language based computer systems are considered in assessing the current level of system development. Finally, certain pervasive difficulties that have arisen in developing natural language based systems are identified, and the app... View full abstract»

    Request is an experimental Restricted English QUESTion-answering system that can analyze and answer a variety of English questions, spanning a significant range of syntactic complexity, with respect to a small Fortune-500-type data base. The long-range objective of this work is to explore the possibility of providing nonprogrammers with a convenient and powerful means of accessing information in f... View full abstract»

  • Conceptual Graphs for a Data Base Interface

    A data base system that supports natural language queries is not really natural if it requires the user to know how the data are represented. This paper defines a formalism, called conceptual graphs, that can describe data according to the user's view and access data according to the system's view. In addition, the graphs can represent functional dependencies in the data base and support inference... View full abstract»

  • Bicubic Patch Surfaces for High-Speed Numerical Control Processing

    Publication Year: 1976, Page(s):358 - 367
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (556 KB)

    Parametric bicubic patch surfaces have been used for some time in manufacture and design. It is convenient to have such surfaces available as standard numerical control surfaces using the APT programming language. A major drawback is that they are costly to use for data processing of numerical control programs. If, however, nonparametric bicubics are used, computer time, and hence cost, can be red...

  • Column Access of a Bubble Lattice: Column Translation and Lattice Translation

    Publication Year: 1976, Page(s):368 - 375
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (567 KB)

    The use of a regular array, or lattice, of magnetic bubbles for the storage of information requires two kinds of functions: the read-write functions involving the generation and discrimination of bubbles with different wall structures, and the access functions involving the insertion and removal of bubbles at selected locations in the lattice. In a column-accessed bubble lattice device, accessing ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (862 KB)

    A high-resolution technique is described for the experimental fabrication of Permalloy patterns for magnetic bubble circuits having linewidths as small as 3000 Å The system includes a computer-controlled electron beam, automatic registration, a modified field-stitching method, and exposure control to compensate for proximity effects. Patterns are formed either by electroplating or by evapor... View full abstract»

  • Design of a Swinging Arm Actuator for a Disk File

    Publication Year: 1976, Page(s):389 - 397
    Cited by:  Papers (8)  |  Patents (16)

    An integral disk enclosure that incorporates a novel head-positioning actuator concept is used in the IBM System/32 and in recently announced terminal controllers, such as the Retail Store Controller and the Communication Controller. Based on a swinging arm rather than the conventional linear carriage, the actuator presented the designers with opportunities to create a simplified mechanism and to ... View full abstract»

  • Fast Beamforming with Circular Receiving Arrays

    The Fast Fourier Transform (FFT) can be applied to circular arrays receiving wideband sonar radiation. As with conventional beamforming, the FFT serves in the first stage to divide the spectrum into narrow frequency bands. Then the array element responses of each band are analyzed in a second stage of FFTs for the Fourier components (modes) of the array excitation function for the respective band....

  • Structure and Magnetic Anisotropy of Amorphous Gd-Co Films

    Publication Year: 1976, Page(s):409 - 411
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (351 KB)

    It is found that the structure of amorphous Gd-Co films, as revealed by x-ray diffraction, is correlated with the magnitude of bias voltage present during the sputter deposition. Films sputter deposited with zero bias voltage typically show one broad peak in an x-ray diffraction spectrum, and films sputter deposited with −100 volts bias show two broad peaks with a shoulder between them. The... View full abstract»
