  • Involving older adults in the design and development of free/open source software

    Creator:
    Davidson, Jennifer L.
    Abstract:
    An age-wave is upon us where many older adults are reaching retirement. Technically experienced older adults have skills that could be directly applied to free/open source software (FOSS) communities, such as project management, programming, and/or knowledge of a rapidly growing end-user population. FOSS is a widely popular, low-cost way to...

  • Longitudinal Analysis of Collaboration in Forked Open Source Software Development Projects

    Creator:
    Azarbakht, Amirhosein "Emerson"
    Abstract:
    Social interactions are a ubiquitous part of our lives, and the creation of online social communities has been a natural extension of this phenomena. Free and Open Source Software (FOSS) development efforts are prime examples of how communities can be leveraged in software development, where groups are formed around communities...

  • Investigating the Effects of Design Quality in OSS Projects

    Creator:
    Mannan, Umme Ayda
    Abstract:
    Software systems are becoming an essential part of the lives of both individuals and organizations, and as a consequence, these systems are getting bigger and more complex. Because of this, the tasks of maintaining the quality in these complex software systems are becoming increasingly difficult. Furthermore, these systems are subject...

  • Environmental variability and system heterogeneity in terrestrial biogeochemical models

    Creator:
    Sierra, Carlos Alberto
    Abstract:
    Ecosystems are highly heterogeneous systems subjected to important levels of environmental variability; however, it is common in terrestrial biogeochemical models to assume homogeneous properties of the elements of the system or constant environmental conditions. For some processes, heterogeneity in these models is treated very simplistically, but there is not much...

  • Effect of pre-rigor ultrapressurization on bovine intramuscular connective tissue

    Creator:
    Gonzalez B., Carlos (Gonzalez Batista)
    Abstract:
    Samples of pre-rigor sternomandibularis muscle from ten steers were pressurized at 15,000 psi for two min at 35°C to investigate the effects of pressurization and incubation time on the thermal stability of collagen. Immediately after pressurization, pH of the treated samples (pH 5.71) was significantly lower (P < 0.05) than...

  • Machine learning for computer architecture design and optimization

    Creator:
    Penney, Drew
    Abstract:
    Machine learning applied to computer architecture has rapidly transitioned from a theoretical novelty to being a driving force behind design, control, and simulation in practically all components. These machine-learning-based methodologies are further notable for their scalability to increasingly complex design challenges, which has allowed these methodologies to surpass the prior...

  • 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...

  • The Deschutes Formation: evidence of extension-enhanced explosivity in the early High Cascades

    Creator:
    Pitcher, Bradley W.
    Abstract:
    The eruptive history of the Quaternary Cascades arc has been relatively well characterized. However, much less is known about the frequency and sizes of explosive eruptions produced by earlier stages of the arc. The Late Neogene Deschutes Formation of Central Oregon preserves a remarkable record of heightened pyroclastic activity during...

  • Semi-volatile organic compounds and developing organisms : accumulation in California mountain tadpoles in the field and fish embryo exposures in the laboratory

    Creator:
    Stanley, Kerri A.
    Abstract:
    The atmospheric transport and deposition of semi-volatile organic compounds (SOCs), including current and historic use pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), to mountain ecosystems may result in the exposure of tadpoles to these SOCs. This exposure has been implicated in amphibian population declines in California. Tadpoles encounter...

  • Distinguishing biological and physical controls on soil respiration

    Creator:
    Phillips, Claire L.
    Abstract:
    Soil respiration, or the combined CO₂ emissions from roots and soil microorganisms, constitutes one of the largest losses of carbon (C) from terrestrial ecosystems. The major drivers of soil respiration, which include soil moisture, temperature, and substrate quality, have been known for some time. Nevertheless, correlations between these drivers and...
