  • 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...

  • Preserving the Planar Dynamics of a CompliantBipedal Robot with a Yaw-Stabilizing Foot Design

    Creator:
    Abate, Andrew M.
    Abstract:
    The ATRIAS agile humanoid robot, along with a number of other spring-mass walking machines, currently have two instabilities: one resulting from inertial forces on the torso which cause the robot to spin like a top, and another resulting from stiff ground collisions which cause chattering of the point-contact toes. This...

  • 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...

  • Determination of cutting forces with asymmetric wedged blades

    Creator:
    Phan, Andrew Vinh
    Abstract:
    Cutting operations using blades appear in several different industries such as food processing, surgical operations, gardening equipment, and so forth. As our society continues to increase our technological prowess, there is an ongoing need to better understand the underlying causes of simple tasks such as cutting so that cutting operations...

  • Investigation of volumetric coupling effects on particle-laden turbulent flows at dilute to moderate loadings

    Creator:
    Cihonski, Andrew John
    Abstract:
    Particle-laden turbulent flows are of great importance in many industrial applications and are sufficiently complex to require multiple methods of study to provide a better understanding of the dominant physical mechanisms present in these processes. This work on large-eddy simulation of particle-laden flows seeks to help provide the building blocks...

  • 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...

  • 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...

  • 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...

  • 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...

    Creator:
    Duvall, Andrew Kenichi
    Abstract:
    The population of minority groups is on the rise in the US, yet still minorities are not proportionally represented in Science, Technology, Engineering, and Mathematics (STEM). Of these minorities there are 4 races/ethnicities that are vastly under represented: Blacks, Hispanics, American Indians/Native Alaskans, and Hawaiians/Pacific Islanders. For the US to...
