  • A paradigmatic framework for flight safety

    Creator:
    Routledge, Garry L.
    Abstract:
    Statistically, travel by air is one of the safest forms of transportation. Yet we continue to experience aviation tragedies. Do we fully understand flight safety or is there another way of looking at the problem? In this work a new way of approaching the question of flight safety is developed,...

  • Weak-supervision Time-series Analysis

    Creator:
    You, Zeyu
    Abstract:
    Efficient time-series analysis can impact multiple application domains such as motif discovery in gene analysis or music data, extracting spectro-temporal patterns in acoustic scene analysis, or annotating and classifying electrical bio-signals (such as ECG, EEG, and EMG) for medical applications. Time-series analysis involves a variety of tasks. To predict future...

  • Performance evaluation and design of multiple time series based forecasting systems

    Creator:
    Chen, Kuei-Lin
    Abstract:
    The study evaluates performances of three multiple time series (MTS) forecasting methods; investigates possible improvements in MTS forecasting operations, and proposes a multiple time series based forecasting system. Time series considered are finite, linear, covariance stationary, and discrete. Specific objectives for the thesis were: (a) conducting comparative studies of MTS...

  • A dietary and morphometric analysis of sceloporine (Iguanidae) lizard populations

    Creator:
    White, Robert Lewis, II
    Abstract:
    Analyses of sympatric and allopatric populations of Sceloporus occidentalis and S. graciosus from central Oregon indicate a high degree of similarity in diet. Relative abundance, the equivalent number of equally common taxa (E), and the probability of similarity (SIMI) were used in the analyses. Shifts in diet between populations of...

  • Seedling recruitment of hairy nightshade and other summer annual weeds in irrigated row crops

    Creator:
    Peachey, Ronald Edward
    Abstract:
    This study evaluated the effects of tillage system, rotational tillage sequences, and winter seed burial depth on weed seedling recruitment in irrigated cropping systems. Notill (NT) planting of vegetable crops reduced emergence of hairy nightshade by 77 to 99% and Powell amaranth emergence from 50 to 87% compared to conventional...

  • Extensions for paired comparisons models

    Creator:
    Kolsky, James D.
    Abstract:
    The Thurstone-Mosteller and Bradley-Terry Models are commonly used to rank items from paired comparisons experiments in which one item in each pair "wins," and to assess the importance of time-independent explanatory variables on such rankings. The first part of this thesis clarifies the use of probit and logistic regression models...

  • Estimation of the order of an autoregressive time series : a Bayesian approach

    Creator:
    Robb, Loretta J.
    Abstract:
    Finite order autoregressive models for time series are often used for prediction and other inferences. Given the order of the model, the parameters of the models can be estimated by least squares, maximum likelihood, or the Yule-Walker method. The basic problem is estimating the order of the model. A number...

  • Knowing your customers : ontological gathering and analysis techniques

    Creator:
    Nix, Anthony A.
    Abstract:
    This research presents a methodology to analyze customer needs and direct the gathering of customer needs that both span the need space and are independent. An ontological categorization, the fundamental research contribution of this work, is created to support both aims of the overall methodology. Providing designers with a customer...
