  • Directional 60 GHz communication networks

    Creator:
    Yildirim, Ferhat (Ahmet Ferhat)
    Abstract:
    It is well known that multipath effects cause inter-symbol interference (ISI) for high-speed signaling and ultimately limit the achievable data rate at any frequency band. In this thesis, we study several different methods to tackle this issue and provide solutions for establishing efficient wireless links that can provide several Gbps...

  • Drop size distributions produced by turbulent pipe flow of immiscible liquids

    Creator:
    Collins, Stanley Browning
    Abstract:
    Drop size distributions produced by the turbulent pipe flow of dispersions of immiscible liquids were measured photographically. A mathematical model was developed which predicted both the shape of the experimentally observed distributions and the experimentally observed kinetics of the breakup process. The mutually saturated water and organic phases were pumped...

  • Epidemiology and population biology of Inonotus tomentosus as a pathogen of forests of British Columbia

    Creator:
    Lewis, Katherine JoAnn
    Abstract:
    The root disease fungus Inonotus tomentosus, common in the old growth boreal forests of British Columbia, poses a threat to the health of second growth forests established on sites with a previous history of root disease. Colonized stumps occur in groups of 1 to 6; the groups are clumped within...

  • Occult cloudwater deposition to a forest in complex terrain : measurement and interpretation

    Creator:
    Kowalski, Andrew S.
    Abstract:
    Occult deposition is the direct uptake of cloudwater by vegetation that comes into physical contact with wind-driven cloud droplets. This can be a significant pathway for hydrological and chemical fluxes from the atmosphere to some forests. Methods for estimating cloudwater fluxes to forests are reviewed. Previous studies have neglected the...

  • Crystallographic studies of Pyrenophora tritici-repentis ToxA

    Creator:
    Sarma, Ganapathy N.
    Abstract:
    Tan spot of wheat is an economically significant disease caused by the fungal pathogen, Pyrenophora tritici-repentis. Certain races of the fungus secrete Ptr ToxA (ToxA), a 13.2 kDa proteinaceous host-selective toxin that is responsible and sufficient to cause disease in susceptible wheat varieties. Disease symptoms develop only when the ToxA...

  • Optimization of seasonal irrigation scheduling by genetic algorithms

    Creator:
    Canpolat, Necati
    Abstract:
    In this work, we first introduce a novel approach to the long term irrigation scheduling using Genetic Algorithms (GAs). We explore the effectiveness of GAs in the context of optimizing nonlinear crop models and describe application requirements and implementation of the technique. GAs were found to converge quickly to near-optimal...

  • Macroeconomic fluctuations and economic growth : the case of Korea

    Creator:
    Yoon, Tae-Yong
    Abstract:
    The thesis presents a useful and effective blend of insights about macroeconomic business fluctuations and the effects of government expenditure in economic growth in Korea. In Chapter I, I show that the joint behavior of key Korean macroeconomic variables is consistent with traditional Keynesian interpretation of macroeconomic business fluctuations by...

  • Safety performance of curve advisory speed signs

    Creator:
    Avelar Moran, Raúl Eduardo
    Abstract:
    Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...

  • John Fiske's philosophy of science : the union of science and religion through the principle of evolution

    Creator:
    Lester, Jacob Franklin
    Abstract:
    Modern science was produced by a Christian society, and although science has had an effect on Christianity, it could not itself remain unaffected. In the second half of the nineteenth century, the subject of evolution was as much a religious as a scientific issue. The battle line was drawn and...
