  • Finite elements analysis of circular cell bulkheads

    Creator:
    Kittisatra, Likhit
    Abstract:
    A mathematical model is developed for the analysis of circular cell bulkheads subjected to gravity loads of cell fill, backfill, lateral pressure, and surcharge load using the finite element method. The finite element circular cell model consists of axisymmetric triangular and/or quadrilateral ring elements for soil and cylindrical shell elements...

  • Behavior of a circular cell bulkhead during construction

    Creator:
    Khuayjarernpanishk, Thanasarn
    Abstract:
    A single cell in a 12 cell bulkhead was instrumented to observe its behavior and confirm design assumptions during construction. Vibrating wire strain gages were employed to measure horizontal strains in sheetpiling webs. These were converted to interlock force at eight locations and three elevations around the cell. The deformed...

  • Seedling recruitment of hairy nightshade and other summer annual weeds in irrigated row crops

    Creator:
    Peachey, Ronald Edward
    Abstract:
    This study evaluated the effects of tillage system, rotational tillage sequences, and winter seed burial depth on weed seedling recruitment in irrigated cropping systems. Notill (NT) planting of vegetable crops reduced emergence of hairy nightshade by 77 to 99% and Powell amaranth emergence from 50 to 87% compared to conventional...

  • Interpreting the circular dichroism of cyclic dimers of amino acids

    Creator:
    Bowman, Richard Leroy
    Abstract:
    Independent systems theory has been used to interpret the circular dichroism (CD) spectra in the vacuum uv of three cyclic dimers of amino acids. First, the theory for rotational strengths is developed in terms of degenerate and nondegenerate group functions. All terms to first order in perturbation theory are kept....

  • Circular dichroism spectroscopy and the conformational analysis of globular proteins in the native and denatured state

    Creator:
    Compton, Larry A.
    Abstract:
    A simple matrix method for the analysis of protein circular dichroism (CD) spectra is presented and used to compute the secondary structure of globular proteins in their native and denatured states. The method uses singular value decomposition and generalized inverse algorithms, and a basis set of CD spectra for proteins...

  • Multi-factor information theory models and their industrial applications

    Creator:
    Shirland, Larry Elwyn
    Abstract:
    This dissertation treats information theory and its applications to the general area of decision making. Specifically, three areas are covered; (1) information theory applied to Bayesian analysis, (2) estimation using multi-factor information channel models, and (3) information theory applied to Markov chain analysis. A major portion of this dissertation concerns...

  • Molecular origins of peptide entrapment in polyethylene oxide layers

    Creator:
    Wu, Xiangming
    Abstract:
    A more quantitative understanding of peptide entrapment and elution from otherwise protein-repellent polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. Here we describe criteria for peptide integration and structural change within the PEO brush, and discuss the reversibility of peptide...

  • Topologically-Guided Robotic Information Gathering

    Creator:
    McCammon, Seth
    Abstract:
    Information gathering tasks, such as terrestrial search and rescue, aerial inspection, and marine monitoring, require robotic unmanned systems to make decisions on how to travel within an environment to maximize or minimize a path-dependent information objective function. The distribution of information throughout the environment is the result of various processes,...
