  • Spectral Analysis of Upper Ocean Surface Wave Structure using χSOLO Floats in the Bay of Bengal

    Creator:
    Ball, Matthew S.
    Abstract:
    Surface waves play a vital role in air-sea interactions, and being able to easily measure them in-situ validates and improves predictive models. Here, we diagnose surface wave properties in the Bay of Bengal using modified vertical SOLO II profiling floats, which are regularly used as part of the Argo ocean...

  • The Disinformation Dozen and Media Misinformation on Science and Vaccinations

    Creator:
    Mabrey, Benjamin E.
    Abstract:
    The COVID-19 pandemic has shed a light on the need for people to trust in medical science. With the need for 70% of Americans to be vaccinated to achieve herd immunity but 30% have reported vaccine hesitancy, now more than ever do we need to redouble our efforts to ensure...

  • The effects of marine biodiversity loss on coastal economics

    Creator:
    McAbery, Emma
    Abstract:
    The oceans are one of humanity’s greatest resources, providing food, raw materials, livelihoods, and protection. More than 3 billion people around the world rely on marine life as a source of protein as well as their livelihood. Seafood is one of the highest traded commodities globally and many major cities...

  • Characterization of Two Aerobic Bacteria from Canada Goose Microflora by Whole Genome Sequence Analyses

    Creator:
    Larkin, Abigail M.
    Abstract:
    The Canada goose (Branta canadensis) monogastric gut is proposed to contain aerobic spore-forming bacteria that produce non-toxin substances that may promote anti-inflammatory immune responses. It is hypothesized that the aerobic bacteria found in samples of Canada goose microflora could have probiotic effects in other avian species or used for commercial...

  • Development of a passive micro-ball valve

    Creator:
    Wangwatcharakul, Worawut
    Abstract:
    A novel design, material, and fabrication method are presented to fabricate a passive micro-ball valve. Microvalves are critical components in microflow control devices used to control the fluid flows in microchannels. These microflow control devices can be integrated with microsensors to form micro analysis systems. Glass/silicon-based fabrication is complicated and...

  • Predicting music emotion with social media discourse

    Creator:
    Beery, Aidan J.
    Abstract:
    Predicting the average affect of a piece of music is a task which has been of recent interest in the field of music information retrieval. We investigate the use of sentiment analysis on online social media conversations to predict a song’s valence and arousal. Using four music emotion datasets -...

  • The Biology and ecology of weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana)

    Creator:
    Tarasoff, Catherine
    Abstract:
    Weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana) infest Kentucky bluegrass seed fields of eastern Oregon. Weeping alkaligrass is an introduced species from Eurasia, whereas Nuttall’s alkaligrass is native to semi arid environments of western North America. These species are often referred to collectively as ‘alkaligrass’; however, for farmers...

  • The impact dynamics of a tennis ball striking a hard surface

    Creator:
    Wang, Jin-cherng
    Abstract:
    The purpose of this research was to study the impact phenomena of a tennis ball striking a hard surface. Stroboscopic photography was used to collect the ball's impact images from seven angles of incidence, ranging from -23 degrees to -70 degrees with zero, top and back initial spin respectively. Through...

  • Automated Tradeoff Analysis of Cost Versus Machinability for Design Feedback

    Creator:
    Grier, Alan Thomas
    Abstract:
    As CAD tools become more sophisticated, engineers are able to more easily create complex part geometries with minimal mass given strength and stiffness requirements. However, these complex part geometries can be difficult to subtractively manufacture, which consequently increases manufacturing cost and production time. This thesis presents a method independent of...
