  • Design considerations for fast-settling operational amplifiers

    Creator:
    Yang, Howard C.
    Abstract:
    The design considerations for fast-settling operational amplifiers (opamps) differ significantly between sampled-data switchedcapacitor (SC) and conventional continuous-time applications. In SC circuits, the shape of the output voltage waveform of an opamp is of no consequence provided that the output settles to within a specified tolerance of its steady-state value prior...

  • Honored values and valued objects : the Society for Creative Anachronism

    Creator:
    Turner, Althea L.
    Abstract:
    In this dissertation, I posited the need to understand how an invented community (the Society for Creative Anachronism) constructs symbolic meaning in material objects and value systems. Using ethnographic methods, I focused on the Knights and their regalia as this is the most widely accepted material symbolism. People go to...

  • Education of American research astronomers, 1876-1941

    Creator:
    Hall, Robert Dale, 1947-
    Abstract:
    The education (particularly graduate education) of Americans who were active in astronomical research between 1876 and 1941 is assessed for its effectiveness in preparing the astronomers for careers in research. This period contains three dynamic changes: the growth of American astronomy in becoming the world's leading community of astronomers, the...

  • Boundaries of research : civilian leadership, military funding, and the international network surrounding the development of numerical weather prediction in the United States

    Creator:
    Harper, Kristine C.
    Abstract:
    American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...

  • Case Study : Description of a Corporate University's Operational Factors

    Creator:
    Ewer, Gary
    Abstract:
    Corporate universities (CUs) have been in existence in the United States since the early 1900s. They are increasingly providing educational and developmental opportunities for workers; however, there is little empirical research on these types of organizations. This study examined a specific electrical distributor's CU using a theoretical framework as a...

  • Understanding how Vietnamese make career decisions in the United States

    Creator:
    Do, Vinh The
    Abstract:
    This research explores the lived experiences and career decision making styles of three Vietnamese refugees in the United states. Since this study involves the lived experience of the participants pertaining to their everyday activities (i.e. living, making decision, and working in the United States), the phenomenological approach (Van Manen, 1990;...

  • Fashion media's role in the debate on millinery and bird protection in the United States in the late nineteenth and early twentieth centuries

    Creator:
    Scarborough, Amy D.
    Abstract:
    The purpose of this study was to explore the possible relationship among fashion media, the social responsibility agenda of the Audubon Society, and the use of birds in millinery in the late nineteenth and early twentieth centuries. Both the content analysis method and the historic method were used to gain...

  • Correlated level shifting as a power-saving method to reduce the effects of finite DC gain and signal swing in opamps

    Creator:
    Gregoire, B. Robert
    Abstract:
    This thesis presents methods to reduce the effects of finite opamp DC gain, output voltage swing limitations in opamps, and component mismatches. The primary contribution of this thesis is a new switched-capacitor method named correlated level shifting (CLS). CLS enables true rail-to-rail operation by storing an estimate of the desired...

    Creator:
    Richards, Linda Marie
    Abstract:
    The atomic age was enacted by many scientists as a way to realize health and human rights. Human rights were conceived in this context as rights to economic development, science education, and nuclear medicine. The United States Atomic Energy Commission (AEC) acted hand in hand with UN agencies and educators...
