  • Submerged jet impingement boiling thermal management

    Creator:
    Cardenas, Ruander
    Abstract:
    Technologies such as avionics and power electronics are driving the demand for thermal management schemes towards high heat fluxes and low surface temperatures. Typically, these applications require the dissipation of heat fluxes in the rage of 100-1000 W/cm² while maintaining surface temperatures lower than about 85 °C. Phase-change heat transfer...

  • Study of the Effects of Chain Whip Length and Bar Length on the Characteristics of Chain Shot

    Creator:
    Shannon, Eric R.
    Abstract:
    Timber harvesters are high powered industrial grade rigs used to fell, delimb, and cut to size large trees. Hydraulic motors power sprockets that drive chains around a guide bar that get extended through logs during cuts. As technological advances allow for higher speeds a phenomenon called “chain shot” has...

  • Amorphous TiO₂ : A Thin Film Synthesis Route to Stabilization of Metastable TiO₂ Brookite

    Creator:
    Haggerty, James E. S.
    Abstract:
    Structure-specific synthesis processes are of key importance to the growth of polymorphic functional compounds such as TiO₂, where material properties strongly depend on structure as well as chemistry. The robust growth of the brookite polymorph of TiO₂, a promising photocatalyst, has been difficult in both powder and thin-film forms due...

  • Nonlinear terahertz spectroscopy of carbon nanomaterials and semiconductor nanostructures

    Creator:
    Paul, Michael Jason
    Abstract:
    This thesis will cover my work relating to the developing field of terahertz (THz) science and technology. It will present experimental and theoretical studies investigating the optical and electrical properties of various material systems using novel THz imaging and spectroscopy techniques. Due to its low photon energy, THz imaging and...

  • Model of student understanding of probability in modern physics

    Creator:
    Wattanakasiwich, Pornrat
    Abstract:
    This study aimed to investigate students' models of probability in a modern physics context. The study was divided into three phases. The first phase explored student pre-knowledge about probability before modem physics instruction. The second phase investigated student understanding of concepts related to probability such as wave-particle behavior, the uncertainty...

  • Modeling Flow and Transport at Pore Scale with Obstructions

    Creator:
    Umhoefer, Joseph G.
    Abstract:
    In this thesis we study mathematical and computational models for phenomena of flow and transport in porous media in the presence of changing pore scale geometries. The differential equations for the flow and transport models at Darcy scale involve the coefficients of permeability, porosity, and tortuosity which depend on the...

  • A thin codimension-one decomposition of the Hilbert Cube

    Creator:
    Phon-On, Aniruth
    Abstract:
    For cell-like upper semicontinuous(usc) decompositions G of finite dimensional manifolds M, the decomposition space M/G turns out to be an ANR provided M/G is finite dimensional ([Dav07], page 129 ). Furthermore, if M/G is finite dimensional and has the Disjoint Disks Property (DDP), then M/G is homeomorphic to M ([Dav07],...

  • Monte Carlo simulations of magnetic semiconducting Superlattices

    Creator:
    Scott, Silas Menlo
    Abstract:
    Computer simulations invoking the Metropolis Algorithm and Monte Carlo techniques were constructed to model the behavior ofvarious systems of magnetic semiconductors. Among the systems modeled were bulk type II FCC antiferromagnets and simple cubic thin films and superlattices. Studies of bulk antiferromagnets revealed dependence of Neel Temperature on nearest neighbor...

  • Nonlinear Terahertz Spectroscopy and imaging of Carbon Nanomaterials

    Creator:
    Lee, Byounghwak
    Abstract:
    This dissertation presents nonlinear terahertz (THz) properties of carbon nanomaterials investigated by time-resolved high-field THz spectroscopy. In order to determine THz characteristics of nanomaterials, we performed THz power spectrum measurement, THz raster imaging, THz time-domain spectroscopy (THz-TDS) and time-resolved pump-probe experiment on two different types of single layer graphene and...

  • Local Accessibility of Objective, Classical Reality

    Creator:
    Kincaid, Joshua J.
    Abstract:
    The fact that measuring a quantum system reduces it to apparently classical behavior, eliminating the interference patterns that are a hallmark of quantumness, cries out for an explanation. That explanation has been provided by the recognition of decoherence,whereby the interference is destroyed by the very interaction that acquires information.We begin...
