  • Evaluating the effectiveness of spare parts replenishment methods for warranty service satisfaction

    Creator:
    Bluett, Andrew H.
    Abstract:
    After a mobile communication device (MCD), such as a smartphone or tablet, has been sold to the public, the customer may find that there is a defect. Each MCD is sold with a warranty that covers the repair of manufacturing defects and is supported by the MCD manufacturer. A third...

  • Non-Myopic Distributed Coordination and Planning for Robotic Teams

    Creator:
    Smith, Andrew
    Abstract:
    As robotic systems become increasingly prevalent in our lives (e.g., by harvesting food, assisting with disaster response and defense, and transporting persons and our goods around the world) there is a growing need to ensure that they can cooperate to achieve their intended goals. Robotic cooperation in the real-world is...

  • Orb Web Vibrations: Modeling, Localization, and Measurement

    Creator:
    Otto, Andrew W.
    Abstract:
    The orb web is a multipurpose structure---serving as a home for its inhabitant spider, as a prey capture device, and as a physical extension of the spider’s sensing abilities. Biologists are particularly interested in the spider’s ability to locate prey trapped in its web by sensing the vibrations induced from...

  • Mechanical Design for Robot Locomotion

    Creator:
    Abate, Andrew M.
    Abstract:
    Robotic limbs have been shown to enable mobility in unstructured, real-world terrain; they allow robots to step around cluttered environments, scramble up hills, carry heavy loads, and even perform acrobatics. However, mechanical limbs cannot operate as a means for such dynamic locomotion if they are simply treated as general articulated...

  • Fiber Reinforced Composite Power-Mooring Cables Design and Manufacturing applied to Wave Energy Converters

    Creator:
    Miller, Andrew
    Abstract:
    The design and analysis of single point power-mooring cables applied to wave energy converters (WECs) is presented. WECs are mechanical devices designed and deployed to extract energy from waves in varying ways, and at varying distances from the shoreline. WEC devices operating on the water surface require mooring lines or...

  • Modeling and simulation of volume displacement effects in multiphase flow

    Creator:
    Cihonski, Andrew John
    Abstract:
    There are many options available when selecting a computational model for two-phase flows. It is important to understand all the features of the model selected, including when the model is appropriate and how using it may affect your results. This work examines how volume displacement effects in two-phase Eulerian-Lagrangian models...

  • The Influence of Fuel Characteristics on Smoldering Behavior through Porous Fuels

    Creator:
    Ross, Andrew H.
    Abstract:
    Smoldering can play a dangerous role in the ignition and spread of wildfires. Naturally occurring fuels consist of multiple layers of organic materials with varying particle sizes due to differences in decomposition stages with fuel depth, yet the influence of particle size on burning behavior is poorly understood. Previous research...

  • Evaluating Stiffness Metrics for Predicting the Cost of Chemical Kinetics Integration

    Creator:
    Alferman, Andrew Thomas
    Abstract:
    Simulations of combustion and reacting flows often encounter stiffness in the equations governing chemical kinetics. Explicit solvers for these ordinary differential equations offer low computational expense, but typically cannot efficiently handle stiff systems. In contrast, implicit methods demand greater expense but offer unconditional stability—as a result, most reactive-flow solvers rely...

  • Experimental characterization of saw chain cutting performance

    Creator:
    Otto, Andrew W.
    Abstract:
    Chainsaw users value cutting performance and safety. Knowledge of the forces exerted during sawing are necessary to understand and improve the cutting performance of saw chain. Additionally, cutting forces can be used to form metrics for evaluating performance tradeoffs when using a safety (i.e. low-kickback) saw chain versus a standard...

  • Template-based control of the bipedal robot ATRIAS

    Creator:
    Peekema, Andrew T.
    Abstract:
    This thesis details the derivation and application of template-based controls on a bipedal robot, as well as a description of the software framework that enabled experimentation. The software framework uses a combination of open-source tools including ROS, OROCOS, EtherCAT, and Xenomai to create a real-time environment for the controllers. The...
