    Profound social and economic changes have taken place since the first group of NACME Scholars began their careers in the late 1970s. Diversity in the work force is today a strategic national advantage. The papers in this issue, taken from recently published journals, reflect the many contributions by NACME Scholars to one important sector—research—over a wide range of fields. View full abstract»

    When multiphase alloys are rapidly heated, it is possible to cause melting of the interface between phases. This is called constitutional liquation if, during melting, the bulk composition is in a nonliquid region of the phase diagram but the tie-line between the liquating phases passes through a liquid region. The liquid produced during constitutional liquation can spread along grain boundaries a... View full abstract»

  • Parallel Image Processing with the Block Data Parallel Architecture

    Many digital signal and image processing algorithms can be speeded up by executing them in parallel on multiple processors. The speed of parallel execution is limited by the need for communication and synchronization between processors. In this paper, we present a paradigm for parallel processing that we call the block data flow paradigm (BDFP). The goal of this paradigm is to reduce interprocesso... View full abstract»

    This paper develops the analytical framework to compare the approximate performance of periodic hypersonic cruise trajectories with previously proposed hypersonic trajectory profiles for global reach. Specifically, range, ΔV, and payload-carrying capacity are evaluated for various trajectory types to illustrate the enhanced performance achieved by flying periodic hypersonic cruise trajector...

    High-frequency planar circuits experience large electromagnetic (EM) coupling in dense circuit environments. As a result, individual components exhibit performance degradation that ultimately limits overall circuit response. This paper addresses crosstalk in planar microstrip lines by evaluating micromachined packages as a means to reduce coupling. Microstrip lines with straight and meandering pat... View full abstract»

    Stability and invertibility of discrete time Polynomial ARMA models are studied in an `extended neighbourhood' to extend the local results obtained earlier. The analysis combines linear robust control and classical nonlinear system theories. Polynomial ARMA models are used as examples illustrating the theory. View full abstract»

  • Frequency Response Sensitivity Functions for Helicopter Frequency Domain System Identification

    Publication Year: 2000, Page(s):748 - 758
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1433 KB)

    This paper addresses some aspects of frequency domain based, state space system identification. A frequency response sensitivity function is developed, and applied to the problem of identifying a coupled rotor-fuselage helicopter model from simulated frequency sweep data. This function indicates how sensitive the frequency response of the model is, at every frequency of interest, to perturbations ... View full abstract»

  • A fuzzy linguistic model for the prediction of carpal tunnel syndrome risks in an occupational environment

    Publication Year: 2000, Page(s):759 - 769
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1252 KB)

    This research presents the development and evaluation of a fuzzy linguistic model designated to predict the risk of carpal tunnel syndrome (CTS) in an occupational setting. CTS has become one of the largest problems facing ergonomists and the medical community because it is developing in epidemic proportions within the occupational environment. In addition, practitioners are interested in identify... View full abstract»

  • Metabolic Effects on Recombinant Interferon-γ Glycosylation in Continuous Culture of Chinese Hamster Ovary Cells

    Asparagine linked (N-linked) glycosylation is an important modification of recombinant proteins, because the attached oligosaccharide chains can significantly alter protein properties. Potential glycosylation sites are not always occupied with oligosaccharide, and site occupancy can change with the culture environment. To investigate the relationship between metabolism and glycosylation site occup... View full abstract»
