  • 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...

  • An approach to reduced-order modeling and feedback control for wave energy converters

    Creator:
    Shoori J., Hesam E.
    Abstract:
    Wave energy holds great promise to be part of the alternative energy portfolio that will provide independence from fossil fuels. As wave energy converter (WEC) technologies mature, designing effective control strategies to extract maximum energy, extend device life, coordinate WEC operation within an array, or mitigate negative impacts of a...

  • Characterization and mitigation of train vibrations in a laboratory facility

    Creator:
    Atanasov, Atanas A.
    Abstract:
    Excessive environmental vibrations can have deleterious effects in a variety of animals. Despite the potentially detrimental effects vibrations may have on animal health and experimental results, they remain poorly understood in the animal laboratory setting. This study investigates the consequences of excessive train vibrations on the breeding success of laboratory...

  • Condensing observation of locale and agents : a state representation

    Creator:
    Valenti, Brett A
    Abstract:
    Computing agents require state information to make coherent and useful decisions. A state representation is a numerical translation of the environment and conditions that are pertinent factors in an agent's decision making. Although many representations, when paired with clever learning algorithms, are able to coordinate and capture prey in specific...

  • Utilizing the thermodynamic properties of E85 to increase the specific efficiency of a high specific output single cylinder Formula SAE engine

    Creator:
    Duncan, Derek N.
    Abstract:
    Formula SAE is a collegiate engineering competition that has participants from around the globe. Of the 1000 points available throughout the event, 100 (10%) are dedicated to the fuel efficiency of the student built race cars. Competition rules allow either gasoline or E85, a mix of 85% ethanol and 15%...

  • Performance of a thermally activated cooling system and design of a microchannel heat recovery unit

    Creator:
    Seward, Ryan
    Abstract:
    The performance of a combined vapor-compression cycle/ORC is evaluated using waste-heat from a diesel generator. A flat plate microchannel heat exchanger is employed to provide energy exchange between the diesel exhaust stream and an oil loop, which provides energy to a boiler. This study finds an increased diesel duty corresponds...

  • Reverse engineering, modeling, and redesign of a vibratory conveyor

    Creator:
    Foglesong, Timothy J.
    Abstract:
    Some successful products are still developed and produced without the benefit of modern design techniques. One such product is a vibratory conveyor that has been developed largely through prototype iteration. The manufacturer has collaborated with Oregon State University to introduce model-based design into the development process. This research details a...

  • Turbulent Combustion Analysis of Large Hydrocarbon Fuels in a Reduced Pressure Environment

    Creator:
    Schorn, Nathan E.
    Abstract:
    The aviation industry is pushing for better fuels and gas turbine engines for several reasons: cost, emissions, and to a lesser extent high-altitude relights. One aspect that research has been focused on to help reduce costs, emissions and better understand high-altitude relights is studying the combustion behavior of the fuel...

  • Design of composite sandwich panels for a Formula SAE monocoque chassis

    Creator:
    Story, Robert D.
    Abstract:
    Physical testing of composite sandwich panels in three point bending is an increasingly important aspect of qualifying a composite monocoque for Formula SAE competition. Required stiffness and strength values have increased over the past three years, and more of the monocoque's laminates must be tested as well. As a result,...
