  • π-line reconstruction formulas in computed tomography

    Creator:
    Hass, Ryan Andrew
    Abstract:
    X-ray computed tomography is a noninvasive imaging modality capable of reconstructing exact density values of 3D objects. Computed tomography machines are deployed across the world to provide doctors with an image that reveals more detail than a standard x-ray image. We investigate algorithms based on exact computed tomography reconstruction formulas...

  • β relaxation and low-temperature aging in a Au-based bulk metallic glass: From elastic properties to atomic-scale structure

    Creator:
    Evenson, Z., Naleway, S. E., Wei, S., Gross, O., Kruzic, J. J., Gallino, I., Possart, W., Stommel, M., and Busch, R.
    Abstract:
    The slow β relaxation is understood to be a universal feature of glassy dynamics. Its presence in bulk metallic glasses (BMGs) is evidence of a broad relaxation time spectrum that extends to deep within the glassy state. Despite the breadth of research devoted to this phenomenon, its microscopic origin is...

  • ZinnJeffreyA1973.pdf

    Creator:
    Zinn, Jeffrey A.
    Abstract:
    Local property-owning residents maintain high levels of interest and awareness regarding a neighboring natural resource complex. Factors, however, such as proximity, personal interests, use patterns and economic considerations cause local inhabitants to have an inaccurate perception of the natural resource complex. The nature of local resident perception can be analyzed...

  • Zinc tin oxide thin-film transistor current mirror circuits

    Creator:
    Feller, Layannah Elizabeth
    Abstract:
    The central focus of this thesis is the design, fabrication and characterization of amorphous oxide semiconductor (AOS) thin-film transistor (TFT) current mirrors. The thin-film deposition and circuit fabrication methods used to realize zinc tin oxide (ZTO) TFT current mirrors are addressed in order to elucidate the processing challenges for this...

    Zhen, Le, Ford, Nicole, Gale, Debra K., Roesijadi, Guritno, and Rorrer, Gregory L.
    Abstract:
    A selective and label-free biosensor for detection of the explosive compound 2,4,6-trinitrotoluene (TNT) in aqueous solution was developed based on the principle of photoluminescence quenching of upon immunocomplex formation with antibody-functionalized diatom frustule biosilica. The diatom frustule is an intricately nanostructured, highly porous biogenic silica material derived from the shells...

  • Zeros of Replicable Functions

    Creator:
    Toomey, Benjamin J.
    Abstract:
    Following the work of Asai, Kaneko, and Ninomiya for Faber polynomials associated to the modular group, and Bannai, Kojima, and Miezaki's partial proof for the case of the Fricke group of level 2, we show that the zeros of certain modular functions for some low-level genus zero groups associated to...

  • Zero kinetic energy photoelectron spectroscopy of triphenylene

    Creator:
    Harthcock, Colin, Zhang, Jie, and Kong, Wei
    Abstract:
    We report vibrational information of both the first electronically excited state and the ground cationic state of jet-cooled triphenylene via the techniques of resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The first excited electronic state S₁ of the neutral molecule is of A₁' symmetry and...

    Zhang, Jie
    Abstract:
    In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...
