  • 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...

  • Capacitive coupling compensation facilitating single-pole switching on six-phase transmission lines

    Creator:
    Al-Shehri, Abdallah M.
    Abstract:
    In this research, a novel shunt compensation scheme design procedure is developed for unbalanced, untransposed n-phase transmission lines. The main function of the scheme is to reduce the effect of the capacitive coupling on untransposed transmission lines to levels where successful single-pole switching is assured. The analysis procedure is carried...

  • 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...

  • On Avoiding Power-Seeking by Artificial Intelligence

    Creator:
    Turner, Alexander M.
    Abstract:
    We do not know how to align a very intelligent AI agent's behavior with human interests. I investigate whether—absent a full solution to this AI alignment problem—we can build smart {\ai} agents which have limited impact on the world, and which do not autonomously seek power. In this thesis, I...

  • Experimental taxonomy, 1930-1950 : the impact of cytology, ecology, and genetics on ideas of biological classification

    Creator:
    Hagen, Joel Bartholemew
    Abstract:
    During the years between 1930 and 1950 a number of attempts were made to introduce techniques and ideas from cytology, ecology, and genetics into the field of taxonomy. Advocates of this "experimental taxonomy" believed that cytological, ecological, and genetic techniques would provide a rigorous, objective methodology to replace the traditional...

  • Distribution, form, and signigicance of plant opal in Oregon soils

    Creator:
    Norgren, Joel A.
    Abstract:
    This study was undertaken to increase knowledge of opal phytoliths in plants and soils of Oregon, and thus encourage further use of phytoliths in future pedologic investigations. Content of plant opal in needles from ten common Oregon conifer species ranged from 0.2 to 7.9%. Western larch (Larix occidentalis) contained the...

  • Satellite structure in the gas-phase X-ray photoelectron spectra of planar unsaturated molecules

    Creator:
    Chambers, Scott Alexander
    Abstract:
    The satellite structure ("shake-up") present in the X-ray photoelectron spectra of several planar molecules containing double bonds has been investigated in the gas phase. This set consists of three five-membered heterocyclic molecules, ethylene and two of its fluorinated analogs, and benzene with three of its fluorinated analogs. In addition, core...

  • Signatures in the Subsurface - Big & Small Data Approaches for the Spatio-Temporal Analysis of Geologic Properties & Uncertainty Reduction

    Creator:
    Rose, Kelly Kathleen
    Abstract:
    Despite more than two centuries of exploration, including more than six million deep wellbores with depths exceeding 40,000 feet in some parts of the world, our ability to constrain subsurface processes and properties remains limited. Characteristics of the subsurface vary and can be analyzed on a variety of spatial scales....

  • Hybrid-Meshnet, a local area mesh network with distributed control

    Creator:
    Kang, Cheoul Shin
    Abstract:
    Hybrid-Meshnet is a communication subnet architecture for local area networks (LANs) designed to achieve a high degree of network performance and flexibility. These objectives are achieved by utilizing a dual channel structure. A token ring is used for short or prioritized data transmissions. A complimentary mesh network with arbitrary data...

  • Nonlinear control applied to power systems

    Creator:
    Vedam, Rajkumar
    Abstract:
    When large disturbances occur in interconnected power systems, there exists the danger that the power system states may leave an associated region of stability, if timely corrective action is not taken. Open-loop remedial control actions such as field-forcing, line-tripping, switching of series-capacitors, energizing braking resistors, etc., are helpful in reducing...
