  • Student views on science and the scientific process : studying changes made in a redesigned non-major introductory science course

    Creator:
    Price, Matthew F.
    Abstract:
    The purpose of this study was to understand how instruction in an introductory nonmajor astronomy course at Oregon State University affects how non-science majors view science and the scientific process. The study used research-based methods to design a reform-based lecture/lab course and implement it for students. Two top-level questions were...

  • Preliminary framework for the run-ahead predictive simulation software (RAPSS)

    Creator:
    Makinson, Kevin A.
    Abstract:
    The Run-Ahead Predictive Simulation Software (RAPSS) is an architecture designed for faster-than-real-time decision support for operators of complex networks. To enable further development of the RAPSS methodology, the necessary proof of principle is illustrated in two applications: decision support for shift technical advisors in nuclear power plant control rooms (RAPSS-STA),...

  • Optical, electronic, and thermodynamic properties of layered mixed anion compounds

    Creator:
    Vielma, Jason Michael
    Abstract:
    Mixed anion compounds that form ZrCuSiAs-type crystal structures exhibit remarkable properties such as superconductivity at low temperatures, hole conduction with optical transparency in the visible region, and exciton absorption at room temperature. In this thesis, properties of a selected group of materials out of the very large set of mixed...

  • An extension of the quantum theory of scattering to the non-asymptotic regime using Bohmian trajectories

    Creator:
    Stenson, Jared R.
    Abstract:
    Quantum mechanics provides a conventional theory of scattering that is limited in at least two ways: it focuses exclusively on the asymptotic regime and, in a more general sense characteristic of all quantum descriptions, provides no concrete account of individual particle evolution in spacetime. This is particularly true during the...

  • 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...

  • Optoelectronic properties of organic semiconductor materials : from bulk to single molecule

    Creator:
    Shepherd, Whitney E. B.
    Abstract:
    The behavior and application of organic semiconductor materials depend strongly on their molecular structure, and molecular interactions. Several studies of intermolecular interactions in functionalized polyacene materials are presented. The degree and onset of aggregation of a functionalized anthradithiophene derivative was studied as a function of concentration in two different host...

  • Community Colleges Creating Academic Programming for Rural Areas

    Creator:
    Garcia-Chitwood, Jean
    Abstract:
    Community colleges serve various populations as part of their missions. Many community colleges serve the people who live in rural communities and are challenged with fewer financial resources. The term rural is not easily defined, and many variables need to be considered when creating academic programming for rural populations. There...

  • 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],...

  • 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...

  • Experimental Investigation of the Transition to Natural Convection in HTGR Applications using the Oregon State SFSETF

    Creator:
    Fishler, Joshua D.
    Abstract:
    High Temperature Gas Reactors (HTGRs) are positioned to disrupt local and global markets via their unique ability to produce carbon-free process heat, high efficiency power generation, and passively safe operational features. However, significant impediments still exist to delay deployment of this particular technology, including a lack of experimental data, verified...
