  • Functional analysis to inform early design decisions for novel systems with substantial operations and maintenance costs

    Creator:
    Algarra, Nathan
    Abstract:
    Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...

  • Realized regulatory complexity : unveiling the hidden effect of regulation structure on product architecture

    Creator:
    Robinson, David Myles
    Abstract:
    Government regulation is an established policy tool for inducing technological innovation in a market. For example, many environmental regulations prescribe performance requirements that industry complies with by innovating aspects of the product design. These design innovations might include updated components, new functionality, or a revised product architecture. However, the effect...

  • Development and validation of acoustic measurement techniques for void fraction in concentric annular geometries

    Creator:
    Tost, Brian C.
    Abstract:
    This work investigates the acoustic velocity of gas-liquid mixtures in vertical, co-current flow in a concentric annulus. Acoustic velocity shows promise as a detection parameter for the presence and amount of gas in a liquid flow because of its high sensitivity to gas void fraction in a gas-liquid mixture. However,...

  • Learning from optimization for bipedal robots

    Creator:
    Yu, Fangzhou
    Abstract:
    Legged robots have consistently captured our collective imagination through various forms of media, from Hollywood films, anime, and viral Youtube videos of robots accomplishing incredible feats of acrobatics. These robots have the potential to navigate our environments, capable of completing tasks that would otherwise require human intervention. However, developing controls...

  • Optical sensing and metrology for on-machine surface inspection in manufacturing processes

    Creator:
    Lee, Eddie T.
    Abstract:
    Optical sensing technologies are pivotal in the manufacturing process, specifically in defect detection, tool condition estimation, and monitoring. The research aims to enhance the accuracy, efficiency, and reliability of manufacturing metrology by employing optical sensing technologies, such as laser profilometers and image processing techniques. The dissertation proposes intelligent and flexible...

  • Mining Temporal Patterns for Prediction: A Mixed-Integer Programming Approach

    Creator:
    Mansourifard, Farzaneh
    Abstract:
    In the past two decades, the advancement in data collection and storage have led to the accumulation of complex datasets. Consequently, various industries have sought data-driven solutions to predict and detect anomalies. Temporal patterns have emerged as potential features in prediction models that could improve the performance of the identification...

  • Modeling hop kilning with respect to energy consumption and drying kinetics

    Creator:
    Thomas, Matthew W.
    Abstract:
    Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

  • Toward Machine Learning-Enabled Adaptivity for Humorous Robots

    Creator:
    Gray, Carson C.
    Abstract:
    Social robots benefit from a sense of humor, which requires the ability to recognize and adapt to human responses during playful interactions. Past work on humorous robots has classified audience responses with audio-based and preliminary visual-based methods following the joke punchline. Building on this progress, we conducted a survey of...

  • Discovery, Processing and Characterization of New Copper and Hafnium-based Metallic Glass Alloys

    Creator:
    Saini, Jaskaran S.
    Abstract:
    Metallic glasses (MGs), also called amorphous metals, are metals or metallic alloys trapped in a disordered glassy state. Their amorphous nature and absence of features such as crystal lattices and defects (dislocations, grain boundaries etc.) endows them with a host of properties that far surpass those of common crystalline materials....

  • Additive Manufacturing of FeCrCoCuNi High Entropy Alloy via Laser Powder Bed Fusion and Nickel Aluminum Bronze via Laser Directed Energy Deposition

    Creator:
    Doyle, Ryan P.
    Abstract:
    High Entropy Alloys (HEA) exhibit unusual properties and are gaining interest as new materials for challenging applications in the aerospace, hypersonic and medical fields. The application of HEAs have been limited by the development of powder production at scale. A recently developed process of plasma spheroidization by 6K, inc. has...
