  • Influence of expansive soils on structures in the Eugene area

    Creator:
    Bonell, John Alexander
    Abstract:
    Expansive soils in Eugene, Oregon present a problem to residents, consultants, contractors, and the city government. During the years 1977 to 1979, the nature and extent of the problem was identified, including an outline of the local occurrence of expansive soils and possible engineering solutions to the most often encountered...

  • Interactions of wind-driven and tidally-driven circulation in the Oregon coastal ocean

    Creator:
    Osborne, John J.
    Abstract:
    Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations). The...

  • Life-Cycle and Playability Analysis of Natural Turfgrass and Synthetic Infill Playing Surfaces Under Field Conditions

    Creator:
    Daviscourt Brian L.
    Abstract:
    The perception of a long-term cost advantage of synthetic infill turf systems relative to natural grass systems has contributed to a rise in their popularity in the USA. However, few comprehensive cost assessments of natural grass and synthetic infill systems exist. There are also no studies looking at interactions between...

  • 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...

  • A study of the effect of the rotor coil couplings of a synchronous machine on its predicted transient response

    Creator:
    Nehrir, Mohammad Hashem
    Abstract:
    The effect of the mutual inductances between the rotor coils of a synchronous machine on its defined reactances and predicted transients are investigated. Two linearized models of the machine are considered. One uses the Laplace-Transform approach, with minimum number of assumptions on the inter-coil couplings, in developing a model for...

  • 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 brushless doubly-fed, stand-alone generator systems

    Creator:
    Gorti, Bhanuprasad V.
    Abstract:
    This thesis introduces a Brushless Doubly-Fed Machine (BDFM), stand-alone generator system. Development of a BDFM current-forced model, along with the analysis of air gap power distribution between the two stator windings and the rotor circuit, pave the way for the characterization and analysis of stand-alone generator systems. The main disadvantage...

  • Frequency-domain, parameter estimation for a brushless, doubly-fed machine

    Creator:
    Ramchandran, Ashok
    Abstract:
    A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages of conventional induction and synchronous types of electrical machines by its unique architecture. The validation of BDFM designs in an actual test environment requires the estimation of the BDFM model parameters from actual experimentation. Accurate values for the parameters...

  • A signal-processed antenna system and the simulation of the effects of balanced-mixer frequency conversion

    Creator:
    Spencer, Kenneth Edward
    Abstract:
    In this paper a signal-processed antenna and receiver system is proposed and analyzed. In addition, a simulation of the balanced-mixer portion of the processing system is made on a hybrid computer to find the bandwidth limitations for the total system. The system utilizes both the amplitude and phase information of...

  • Microstrips on gold-doped silicon substrates

    Creator:
    Lai, Cheng-wen
    Abstract:
    The power dissipation of microstrip transmission-line on gold-doped silicon substrates was investigated. The gold-doping was applied to a regular n-type silicon substrate with resistivity of 5 to 10 ohm-cm. Insertion-loss tests were employed to measure the power dissipation of the microstrips. Power dissipation somewhat less than that for intrinsic silicon...
