  • Quantification of total and plastic 3D strain fields within micro-damaged polyurethane foam

    Creator:
    Sutton, Matthew T.
    Abstract:
    Local material damage that occurs within cellular solids, such as polymer foams and trabecular bone, and precedes local fractures of the cell struts or walls is called micro-damage. The accumulation of micro-damage within cellular solids is often undesirable, although it is thought to be vital to the development and health...

  • Experiential-based learning in engineering project management within a global economy

    Creator:
    Miles, Evan S.
    Abstract:
    Introduction Over the past century, great technological advances have enabled high-speed communication and transportation across the globe. This technology trend combined with the needs of continuous expansion of market place has motivated major corporations not to restrict their business activities to within a single principality. Engineering design activities can take...

  • Navigation and coordination of autonomous mobile robots with limited resources

    Creator:
    Knudson, Matthew D.
    Abstract:
    The use of autonomous robots in complex exploration tasks is rapidly increasing. Indeed, robots can provide speed and cost effectiveness in many tasks, as well as allow operation in environments that are hostile to humans. In this dissertation we: 1) provide two adaptive navigation algorithms; 2) develop a coordination mechanism;...

  • Applying hierarchical and adaptive control to coordinating simple robots

    Creator:
    Knudson, Matthew D.
    Abstract:
    Coordinating multiple robots to achieve a complex task requires solving two distinct control problems: the high-level control problem of ensuring that each robot aims to perform a useful task (e.g., coordination) and the low-level control problem of ensuring that each robot actually performs the correct actions to achieve its task...

  • Learning from action not taken in multiagent systems

    Creator:
    Khani, Newsha
    Abstract:
    Coordination in large multiagent systems in order to achieve a system level goal is a critical challenge. Given the agents' intention to cooperate, there is no guarantee that the agent actions will lead to good system objective especially when the system becomes large. One of the primary difficulties in such...

  • Optimal soaring by a small autonomous glider

    Creator:
    Kyle, Jason A.
    Abstract:
    Extending the flight time of an autonomous unmanned air vehicle by soaring is considered. A suboptimal controller is developed and successful static soaring is demonstrated with a 6 degree of freedom glider model. Altitude gain rates of between ¼ and ½ m/s are achieved with this simple implementation. A hybrid...

  • Quantitative comparison of full field strains experimentally measured and analytically predicted for aluminum foams

    Creator:
    Rutschman, Scott A.
    Abstract:
    Metallic foams have become widely available and have unique properties that make them attractive for use in a variety of engineering applications. Due to their complex structure, the behavior of foams under complex loading conditions is a subject of continued research. Digital volume correlation is a technique wherein full-field strains...

  • Spatio – temporal temperature variations during droplet impingement evaporation : effects of nanofluid and nano-structured surface

    Creator:
    Graber, Christof
    Abstract:
    Droplet and spray impingement cooling are typically used in high heat flux thermal management. In this thesis, droplet impingement and evaporation heat transfer characteristics are determined from measured spatially- and temporally- varying fluid and surface temperatures. Unique to this study is the documentation of the effects of using a nanofluid...

  • A hierarchical neuro-evolutionary approach to small quadrotor control

    Creator:
    Shepherd, Jack F., III
    Abstract:
    Quadrotors are unique among Micro Aerial Vehicles in providing excellent maneuverability (as opposed to winged flight),while maintaing a simple mechanical construction (as opposed to helicopters). This mechanical simplicity comes at a cost of increased controller complexity. Quadrotors are inherently unstable, in the sense that they are essentially unflyable by a...

  • Mixed reactant single chamber fuel cell, using products generated from the electrolysis of an aqueous electrolyte

    Creator:
    Jost, William C.
    Abstract:
    A Mixed Reactant Single Chamber (MRSC) Fuel Cell is a relatively recent concept in the field of fuel cell engineering originally developed in the late 1950’s. Typical fuel cells have separated reactants (a separated fuel and oxidizer) that react on their usually non-selective electro-catalytic materials. A mixed reactant fuel cell...
