  • Mean fronts and frontogenesis near the Asian east coast

    Creator:
    Marlia, J. Christopher
    Abstract:
    The association of frontal formation, development, and movement with large scale baroclinity is well documented. This investigation deals with the mean large-scale baroclinic zones near the Asian East Coast for the last two weeks of February 1975. Two deep, large-scale baroclinic zones are found to be situated along the axis...

  • The marine air penetration of the southern Willamette Valley and its effect upon agricultural field fires

    Creator:
    Sielaff, Carl Ogden
    Abstract:
    This research consists of two related yet distinct studies: an observational study of the surface character of the penetration of marine air into the southern Willamette Valley and a climatological study of the summertime air masses of northwestern Oregon. For the observational study, temperature and estimated wind data were gathered...

  • Optimal inspection policies for a partially observable process with hazardous inspections

    Creator:
    Chou, Chung-kuang
    Abstract:
    An inspection model is considered in which inspections are hazardous to the device being monitored. The model is formulated as a partially observable Markov decision process. Previous research has determined the optimal ongoing inspection policies for a previously inspected device. In this thesis, the optimal inspection initiation policies are investigated...

  • Analysis of dichotomous response models for low-dose carcinogenic risk estimation

    Creator:
    Tabesh, Taraneh
    Abstract:
    Several dichotomous-response models of carcinogenesis are discussed and their implications for low-dose risk estimation are examined. In addition, a pharmacokinetic model incorporating non-linear kinetics is studied and the results are investigated with respect to multiple-pollutant exposures. None of these models appears to suggest the existence of "thresholds". The analysis of...

  • A hazardous-inspection model with costly repair

    Creator:
    Yang, Minghui
    Abstract:
    An inspection-repair model is developed that presumes inspection is hazardous to the system being inspected. The form of the optimal inspection-repair policy is determined for different ranges of the model's parameters. The model is formulated as a partially observable Markov decision process with finite numbers of states and actions. The...

  • Characterization and removal of unstable proteins from grape juice and wine

    Creator:
    Hsu, Juinn-chin
    Abstract:
    Improved sensitive techniques were developed for the determination of soluble proteins in grape, juice and wine. These techniques which permitted direct sample analysis without prior dialysis or concentration, were used for: 1) characterization of heat unstable proteins, 2) evaluating the effect of bentonite fining and ultrafiltration (UF) on the soluble...

  • Ultrafiltration of fruit juice and wine

    Creator:
    Flores Gaytan, Jose Humberto
    Abstract:
    The possible effect of oxidation [processing with or without sulfur dioxide (±S0₂)] and of pre-ultrafiltration treatment of juices with enzymes and fining agents on flux, and on juice color, composition and stability was investigated. White Riesling juice was ultrafiltered with a Romicon system operated with a nominal molecular weight cut-off...

  • Malate and tartrate in Oregon grapes

    Creator:
    Norton, Kerry M.
    Abstract:
    In western Oregon the titratable acidity of grapes at harvest may in some seasons be higher than desirable for making quality wine, due to the retention of malic acid. The purposes of this study were 1) to investigate the effects of a vineyard cultural practice, cluster exposure at veraison by...
