  • From running birds to walking robots : optimization as a unifying framework for dynamic bipedal locomotion

    Creator:
    Hubicki, Christian M.
    Abstract:
    Bipedal locomotion is a complex phenomenon to understand and control, making it difficult for legged robots to achieve the speed, agility, efficiency, and robustness of their animal counterparts. This thesis argues for the use of numerical optimization to investigate and implement bipedal control as it applies to biology, dynamical models,...

  • Analysis of the Effects of Combustion Products on Forced Ignition and Turbulent Flame Propagation

    Creator:
    Bonebrake, Jonathan M.
    Abstract:
    Practical combustion devices frequently rely upon forced ignition of turbulent fuel/oxidizer mixtures that also contain the product species of combustion. Examples of this include engines that use exhaust gas recirculation (EGR), inter-turbine burners in aircraft engines, and other systems the utilize staged combustion. In this work, the effects of major...

  • 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...

  • Gathering information rich customer needs for inclusive product design

    Creator:
    Armstrong, Jessica
    Abstract:
    This work explores a framework for the gathering and analysis of information rich customer needs, with the goal of informing inclusive product design practice. The goal is to be able to provide information and experience to designers so that they can better understand the needs of exceptional users and include...

  • A framework for assessing and improving the resilience of complex engineered systems during the early design process

    Creator:
    Mehrpouyan, Hoda
    Abstract:
    As modern systems continue to increase in size and complexity, they pose significant safety and risk management challenges. System engineers and much of the government research efforts are focused on understanding the attributes and characteristics that emerge from the interactions of components and subsystems. As a result, the objective of...

  • Risk- and Reliability-Based Design Optimization in Offshore Renewable Energy Systems

    Creator:
    Clark, Caitlyn E.
    Abstract:
    Offshore wind and wave energy have the potential to be significant sources of future global electricity production, reduce carbon emissions, decrease dependence on energy importation, and stimulate economic growth in coastal and remote areas. Fixed-foundation and floating offshore wind and wave energy technologies are at different stages of development, but...

  • Generalized Preconditioning to Accelerate Simulations with Large Multiphase Chemical Kinetics Models

    Creator:
    Walker, Anthony S.
    Abstract:
    Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...

  • Resilient Design for Complex Engineered Systems in the Early Design Phase

    Creator:
    Keshavarzi, Elham
    Abstract:
    There are many uncertainties that complex engineered systems will face throughout their lifecycles due to changes in internal and external conditions. It is desirable for complex engineered systems to be resilient against various uncertainties. The ability to overcome such uncertainties should be embedded into the system from the beginning. However,...

  • Providing Informative Feedback for Learning in Tightly Coupled Multiagent Domains

    Creator:
    Rockefeller, Golden C.
    Abstract:
    Autonomous agents that sense, decide, act, and coordinate effectively with each other are critical in many real-world domains such as autonomous driving, search and rescue missions, air traffic management, and underwater or deep space exploration. All such domains share a key difficulty: though high-level mission goals are clear to system...

  • Vehicle routing and scheduling with delivery and installation

    Creator:
    Kim, Kyoung Cheol
    Abstract:
    For manufacturing and service industries to stay competitive in this rapidly changing, globalized world, one of the most important operations, and one that many businesses struggle to plan and manage efficiently, is material handling. There has been a large amount of research on various vehicle routing problems (VRPs) in recent...
