  • Spherical mirror resonators and optical mode selection

    Creator:
    Adrion, Robert Foisy
    Abstract:
    This is a review paper based on recent literature in the areas of spherical mirror resonators and optical mode selection. The Fabry-Perot interferometer with spherical mirrors has been widely used as a laser resonator. The modes of oscillation, diffraction losses and resonance condition are determined for the confocal resonator, i.e....

  • Analysis of the D. C. electric field for a pipeline in a three layered earth

    Creator:
    Brandenstein, Albert Edward
    Abstract:
    This paper develops an equation, from an heuristic set of assumptions, which describes the axial current, leakage current, resultant electric field, and resultant earth potential occurring when a pipeline buried within a resistive earth is subjected to a distributed, primary, axial, electrostatic field produced from a high-voltage, direct-current (HVDC) power...

  • Analysis and synthesis of exponentially tapered, nonuniform transmission line impedance transformers

    Creator:
    David, Frank Kolar
    Abstract:
    The exponentially tapered, nonuniform transmission' line, applied as an impedance transformer, is analyzed and modified. The analysis develops an expression for the input reflection coefficient that has the magnitude and phase as distinct functions. This allows ease in comparing the approximate and exact solutions and in developing the S-parameters for...

  • Instrumentation system for high speed data sampling of electrical machinery

    Creator:
    Brisbine, Glen Edward
    Abstract:
    The objective of this thesis is to develop criteria for a data acquisition system for electrical machinery capable of sampling a signal every 0.2 msec with a desired accuracy of 0.1%. The system to be measured includes both AC and DC voltage and current signals from several points. The main...

  • Identification of synchronous machine parameters

    Creator:
    Shaban, Ali Omar
    Abstract:
    The synchronous machine is an essential component of a power system and determination of its parameters accurately is an important task in securing adequate modes of operation through certain control strategies. An estimation technique based on the Powell algorithm was evaluated for the identification of these parameters on the basis...

  • Applications of mathematical programming techniques in optimal power flow problems

    Creator:
    Li, Ruqi
    Abstract:
    In the past two decades, a great amount of attention has been paid to investigating the economic and safe operation of power systems using modern mathematical techniques. The classic economic dispatch problem, now often called the Optimal Power Flow problem, has been formulated as a mathematical optimization problem and has...

  • Effect of row cover and supplemental Ca fertilization on blossom-end rot in bell pepper (Capsicum annuum var. annuum, Grossom Group)

    Creator:
    Alexander, Shara E.
    Abstract:
    A 2-year trial was conducted at Oregon State University's Hermiston Agricultural Research and Extension Center to examine the effects of spunbonded row cover and supplemental calcium fertilization on blossom-end rot in two varieties of bell pepper. Blossom-end rot is a common cause of bell pepper yield losses, especially at the...

  • A second look at Alexander Pope and Newtonian science

    Creator:
    Reid, Tim S.
    Abstract:
    "This Long Disease, My Life": Alexander Pope and the Sciences by Marjorie Nicolson and G.S. Rousseau has been the standard work on Alexander Pope and Newtonian science ever since it was published in 1968. Literary scholars and biographers continue to be swayed by its influence. Unfortunately, the work they so...

  • Mitigation of Microbiological Water Quality by Last Irrigation-to-Harvest Intervals

    Creator:
    Emch, Alexander W.
    Abstract:
    Foodborne outbreaks involving fresh produce have been on the rise since the late 1990's. Pathogens such as Salmonella spp. and Escherichia coli are prevalent in agricultural environments and commonly travel between farms via irrigation water. The Food Safety Modernization Act (FSMA) has placed an increased emphasis on microbiological standards of...
