  • A universal CMOS current-mode operational amplifier

    Creator:
    Botelho, Cindy
    Abstract:
    It has become customary in electrical engineering to think of signal processing in terms of voltage variables to the exclusion of current variables. This tendency has resulted in voltage signal processing circuits such as voltage-controlled voltage sources (VCVS) and voltage-mode operational amplifiers. However, the VCVS operational amplifier has several limitations...

  • History and analysis of the creation research society

    Creator:
    Elliott, William E.
    Abstract:
    The resurgence of creationism the past few years has been led by advocates of recent-creationism. These individuals, a minority among creationists in general, argue that the entire universe was created approximately 10,000 years ago in one six-day period of time. Recent-creationists support their position by appealing to the Genesis account...

  • Opamp characterization techniques

    Creator:
    Ramamurthy, Karthik
    Abstract:
    Standard methodologies exist for testing and characterizing digital circuits but the same cannot be said of analog circuits. Though much theoretical work has been done to model the linear and nonlinear aspects of analog circuits, a firm practical background for the design of testable analog cells has yet to be...

  • The Ibis, journal of the British Ornithologists' Union : a pre-synthesis portrait

    Creator:
    Johnson, Kristin Renee
    Abstract:
    In 1959 the British Ornithological journal, The Ibis, published a centenary commemorative volume on the history of ornithology in Britain. Over the previous few decades, the contributors to this volume had helped focus the attention of ornithologists on the methods, priorities, and problems of modem biology, specifically the theory ofevolution...

  • Southern Ocean Science and Society: Case Studies at the Nexus of Research, Education, and Policy

    Creator:
    Hann, Ashley M.
    Abstract:
    Even in remote environments, human and natural systems are connected. Pressing environmental and social changes warrant the field of science to not only continue to enhance understanding of the natural world, but also consider the socio-ecological implications of research in the coupled human-natural system. Additionally, a need exists for communication...

  • A chopper-stablized CMOS operational amplifier

    Creator:
    Ann, Seung-Han
    Abstract:
    The chopper-stabilized operational amplifier has good low frequency noise properties. Unfortunately a simple technique for simulation of the chopper-stabilized operational amplifier has not been available. This thesis describes the implementation of a differential amplifier using chopper stabilization and its circuit modeling for the SPICE simulation. This circuit has been designed...

  • The Hanford Laboratories and the growth of environmental research in the Pacific Northwest, 1943 to 1965

    Creator:
    Ellis, D. Erik
    Abstract:
    The scientific endeavors that took place at Hanford Engineer Works, beginning in World War II and continuing thereafter, are often overlooked in the literature on the Manhattan Project, the Atomic Energy Commission, and in regional histories. To historians of science, Hanford is described as an industrial facility that illustrates the...

  • Effects of a resistance exercise program on activities of daily living of elderly women

    Creator:
    DeVries, Christine L.
    Abstract:
    The purpose of this study was to determine if a 5-month progressive-resistance exercise program would affect measures of activities of daily living (ADLs) and functional stability in elderly women. All subjects were ambulatory women, 80 to 93 years old, who lived in assisted-care facilities. Eight exercise and 7 control subjects...

  • A comparison between anthropometric regression equations and hydrostatic weighing for predicting percent body fat of adult males with Down Syndrome

    Creator:
    Ovalle, Steven E. (Steven Edward)
    Abstract:
    The purpose of this study was to compare the accuracy of eight anthropometric regression equations with hydrostatic weighing for predicting the percent body fat of adult males with Down Syndrome (DS). Body fat percentages were predicted for 18 adult males with DS. Skinfold, circumference, and bioelectric impedance analysis data were...

    Creator:
    Sierra, Nelson
    Abstract:
    The purpose of this investigation was to determine the validity and reliability of the Nicholas Manual Muscle Tester (NMMT), a portable dynamometer, as a measure of the isometric strength in women with arthritis. Female subjects (N=13; 66 ± 13.89 yrs.) with arthritis were tested for isometric muscle strength on the...
