  • Arc distribution and motion during the vacuum arc remelting process as detected with a magnetostatic approach

    Creator:
    Woodside, Rigel
    Abstract:
    Currently, the temporal arc distribution across the ingot during the vacuum arc remelting (VAR) process is not a known or monitored parameter. It is has previously been shown that arcs can spatially constrict during VAR, and this constriction can lead to undesired defects in the material. Additionally, correct accounting for...

  • Vacuum evaporated dielectrics in MOS structures

    Creator:
    Delzer, Dennis Richard
    Abstract:
    Vacuum evaporated dielectrics for use in MOS structures were studied in this research project. Dielectric films were deposited on substrates by electron bombardment evaporation of sapphire and quartz source materials. These deposited films were studied using infrared spectroscopy, index of refraction, density, and dielectric constant measurements. Etching tests were also...

  • John Archibald Wheeler : a study of mentoring in modern physics

    Creator:
    Christensen, Terry M.
    Abstract:
    This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

  • Exploring the structural dynamics of human understanding : an historico-philosophical analysis of the problem of meaning in Heidegger and Bohr

    Creator:
    Tattersall, Mason
    Abstract:
    This dissertation explores the structural dynamics of human understanding and particularly the concept of meaning and its connections to concepts of ultimate ground, necessity and contingency, language, and perception. It focuses on the history of the concept of meaning in early twentieth-century European physics and philosophy, through an analysis of...

  • High-linearity switched-capacitor circuits in digital CMOS technologies

    Creator:
    Yoshizawa, Hirokazu
    Abstract:
    In this thesis, novel design techniques have been proposed for implementing high-linearity SC circuits in a standard digital CMOS process. They use nonlinear MOSFET capacitors instead of linear double-poly capacitors. To reduce their nonlinearities, a bias voltage is applied to keep MOSFET capacitors in their accumulation regions. For further reduction...

  • Random dopants and low-frequency noise reduction in deep-submicron MOSFET technology

    Creator:
    Miller, Drake A.
    Abstract:
    The future of mixed-signal, memory, and microprocessor technologies are dependent on ever increasing analog and digital integration, higher cell densities, and demand for more processing power. As a result MOSFET device dimensions continue to shrink to meet these demands. A side effect of device scaling is increased variability at each...

  • The role of ethanol and certain ethyl esters in the fruity flavor defect of Cheddar cheese

    Creator:
    Bills, Donald D.
    Abstract:
    During the course of ripening, Cheddar cheese frequently develops a flavor defect described as fruity. Recent work has indicated that the use of certain starter cultures ultimately results in the development of the defect as the cheese ages. The flavor compounds responsible for the defect, however, have not been elaborated....

  • Flavor chemistry of irradiated milk fat

    Creator:
    Khatri, Lakho Lilaram
    Abstract:
    Increasing interest has been shown in the irradiation sterilization and irradiation pasteurization of foods, but problems of off-flavors and odors are still unsolved, especially in the case of dairy products. From the flavor chemistry point of view, milk lipids are very highly susceptible to irradiation effects. Therefore, this investigation was...

  • Karl Jordan : a life in systematics

    Creator:
    Johnson, Kristin Renee
    Abstract:
    Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the...
