  • Integrated Evaluation of Drinking Water Purification: A Mixed-Method Laboratory and Field Assessment of a Biomass-Powered Water Treatment Technology

    Creator:
    Burleson, Grace Ellen
    Abstract:
    The global water crisis is defined as one of the major threats facing humankind over the next decade with over 1 in 10 people lacking access to clean drinking water worldwide. An estimated 1.2 million people pasteurize their drinking water by using boiling as an indicator. Pasteurization is the process...

  • Design, analysis, and validation of composite c-channel beams

    Creator:
    Koski, William C.
    Abstract:
    A lightweight carbon fiber reinforced polymer (CFRP) c-channel beam was previously designed using analytical theory and finite element analysis and subsequently manufactured through a pultrusion process. Physical testing revealed the prototype did not meet the bending and torsional stiffness of the beam model. An investigation revealed that the manufactured prototype...

  • Further Development of MPM and its Applications in Modeling Wood-Adhesive Bonds

    Creator:
    Hammerquist, Chad C.
    Abstract:
    This work is a culmination of a series of published works related to the use of the Material Point Method (MPM) in modeling wood adhesive bonds. The use of wood as construction material has the potential to play a small role in the solution to the current CO2 and climate...

  • Vertical Axis Pendulum Wave Energy Converters : Investigating Control Strategies and the Deployment of a Scaled Generic Prototype

    Creator:
    Boren, Blake C.
    Abstract:
    Vertical Axis Pendulum Wave Energy Converters (VAPWECs) are thought to be both effective and robust at converting ocean wave energy into usable electricity. Seeking to build upon and investigate such potential, this work examines the merits of actively controlling a generic VAPWEC's pendulum for the purpose of increasing the converter's...

  • On the modeling and control of horizontal pendulum wave energy converters

    Creator:
    Boren, Blake C.
    Abstract:
    Presented is an investigation into the modeling, active control design, and simulation of a generic horizontal pendulum wave energy converter, known as a PWEC. A description is provided of the dominant attributes PWECs have, showcasing their promising potential as wave energy converters. Seeking to further promote this potential, an active...

  • The experimental characterization of membrane behavior in two-phase gas extraction

    Creator:
    Cappello, Nicholas C.
    Abstract:
    Understanding the behavior of hydrophobic membranes is important for applications where separating a gas from a liquid-gas mixture is beneficial. For example, in-situ vapor extraction can be used in microscale heat sinks to improve heat transfer and flow stability. In this study, gas is experimentally evaluated flowing through flexible polytetrafluoroethylene...

  • Numerical study of droplet formation with nozzle dynamics and multiple droplet impingement

    Creator:
    Sangplung, Saangrut
    Abstract:
    Droplet formation from a flexible nozzle plate driven by a prescribed-waveform excitation of a piezoelectric is numerically investigated using a computational fluid dynamics (CFD) model with the VOF method. The droplet generator with a flexible nozzle plate, which is free to vibrate due to the pressure acting on the plate,...

  • Towards reliable and survivable ocean wave energy converters

    Creator:
    Brown, Adam C.
    Abstract:
    Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...

  • The fracture toughness of medium density fiberboard and other fiber bridging composites

    Creator:
    Matsumoto, Noah T.
    Abstract:
    In many composites, fiber bridging develops as part of the fracture process. Fiber bridging invalidates many toughness evaluation methods such as the ASTM E399 and complicates the identification of crack length, which is a necessary parameter in energy methods. In order to measure the toughness of fiber bridging composites, an...

  • Passive dynamics and their influence on performance of physical interaction tasks

    Creator:
    Kemper, Kevin C., II
    Abstract:
    For robotic manipulation tasks in uncertain environments, research typically revolves around developing the best possible software control strategy. However, the passive dynamics of the mechanical system, including inertia, stiffness, damping and torque limits, often impose performance limitations that cannot be overcome with software control. Discussions about the passive dynamics are...
