  • Hawaiian duck (Anas wyvilliana) behavior and response to wetland habitat management at Hanalei National Wildlife Refuge on Kaua'i

    Creator:
    Malachowski, Christopher P.
    Abstract:
    The endangered Hawaiian Duck (koloa maoli; Anas wyvilliana), a non-migratory and island-endemic species, experienced a significant population decline during the twentieth century due to factors such as habitat loss, overharvest, introduced mammalian predators, and hybridization with introduced feral Mallards (A. platyrhynchos). A key objective for Hawaiian Duck recovery is to...

  • Movement Ecology and Population Dynamics of the Endangered Hawaiian Duck (Anas wyvilliana)

    Creator:
    Malachowski, Christopher P.
    Abstract:
    Fundamental objectives in the field of conservation biology involve understanding the processes that influence small and declining populations and applying that knowledge to develop appropriate monitoring strategies and targeted management and conservation actions. Critical first steps in determining the relative role of factors that drive population declines involves estimation of...

  • Mahler's order functions and algebraic approximation of p-adic numbers

    Creator:
    Dietel, Brian Christopher
    Abstract:
    If P is an integer polynomial denote the degree of P by ∂(P) and let H(P) be the maximum of the absolute value of the coefficients of P. Define Λ(P)=2[superscript ∂(P)]H(P) and for a fixed prime p let C[subscript p] denote the completion of the algebraic closure of the p-adic...

  • Xenobiotic biotransformation in aquatic organisms

    Creator:
    Schlenk, Daniel K.
    Abstract:
    Aquatic animals are exposed to a variety of natural and anthropogenic xenobiotics. Biotransformation of xenobiotics was examined in three aquatic animals: a primitive mollusc (chiton); a shellfish which is an important human food source (oyster); and, a lower vertebrate model for toxicological studies (rainbow trout). Since digestive glands of Cryntochiton...

  • The optimization of thin film p-CuO/n-ZnO heterostructures for use in selective gas detection

    Creator:
    Dandeneau, Christopher S.
    Abstract:
    Since bulk p-CuO/n-ZnO heterocontacts were first proposed for gas detection, rapid development has taken place in improving the overall functionality of these structures. While bulk heterocontacts have been shown to exhibit desirable sensitivity and selectivity characteristics, these devices suffer from innate diffusion and ZnO/CuO connectivity drawbacks that limit their effective...

  • A 3-D Tomographic Model of the P-wave Velocity Structure of the Central Cascadia Forearc

    Creator:
    Kenyon, Christopher Bradford
    Abstract:
    Signals from the R/V Langseth’s tuned airgun array were recorded on an array of 33 EarthScope FlexArray seismometers deployed in the Oregon Coast Range from 43.5° to 45°N as part of the 2012 Ridge2Trench experiment to image the structure of the Juan de Fuca plate. This segment of the Juan...

  • Evaluation of collaborative filtering and content based filtering recommenders in jTutors (an online intelligent tutoring system)

    Creator:
    Appasamy, Bharatwaj
    Abstract:
    Software engineers often need help with discovering and learning how to use APIs. For example, software engineers who are starting to learn Java, and they want to implement a certain feature in a program, they might want to reuse existing APIs in order to save time versus rewriting it themselves...

  • Detecting bad smells in spreadsheets

    Creator:
    Asavametha, Atipol
    Abstract:
    Spreadsheets are a widely used end-user programming tool. Field audits have found that 80-90% of spreadsheets created by end users contain textual and formula errors in spreadsheets. Such errors may have severe negative consequences for users in terms of productivity, credibility, or profits. To solve the problem of spreadsheet errors,...

  • Helping end-user programmers find and fix performance problems in visual code

    Creator:
    Chambers, Chris
    Abstract:
    End-user programmers often struggle to create programs that run quickly and effectively, which can be a major deterrent in completing their tasks as desired. Current research has primarily focused on catching user mistakes, such as errors or misused formulas. However, end users deal with issues other than just correctness. In...

  • Mapping Software Development Tool Design to Information Foraging Theory

    Creator:
    Nabi, Md Tahmid-un
    Abstract:
    The design of programming tools is slow and costly. To ease this process, we have developed a design pattern catalog aimed at providing guidance about how to design tools for developers. This guidance is grounded in Information Foraging Theory (IFT), which empirical studies have shown to be useful for understanding...
