  • Characterization and mitigation of train vibrations in a laboratory facility

    Creator:
    Atanasov, Atanas A.
    Abstract:
    Excessive environmental vibrations can have deleterious effects in a variety of animals. Despite the potentially detrimental effects vibrations may have on animal health and experimental results, they remain poorly understood in the animal laboratory setting. This study investigates the consequences of excessive train vibrations on the breeding success of laboratory...

  • Experimental Classification of Intralaminar Matrix Compression Damage Propagation in Carbon Fiber Reinforced Polymers

    Creator:
    Daniels, Mitchell Alan
    Abstract:
    Composites often are able to carry more load after damage due to the structure of laminates. In addition, damage can be difficult to detect in composites compared to homogeneous materials. Understanding the behavior of composite material after damage is vital for composite structural design. Currently, experimental methods exist for classifying...

  • Characterizing Linkages Between the Climate, Cryosphere, and Impacts on Run-of-River Hydropower in Data-Sparse Mountain Environments

    Creator:
    Mosier, Thomas M.
    Abstract:
    In many regions of the world, a significant portion of the surface water originates in mountain headwaters where the timing and magnitude of streamflow is largely dictated by the seasonal storage of precipitation as snowpack and long-term storage as glaciers. Accumulation, persistence, and melt of snow and ice are functions...

  • Proportional integral derivative control of an oil-heated fractal-like branching microchannel desorber

    Creator:
    Davis, Keith R.
    Abstract:
    A PID controller was designed to control the performance of an oil-heated fractal-like branching microchannel desorber for use in an ammonia-absorption refrigeration system. Both the amount and concentration of ammonia refrigerant generated at the desorber can be controlled by choosing the rectified circulation ratio as the controlled variable in a...

  • Model predictive control for sagittal plane locomotion

    Creator:
    Maunder, Cary R.
    Abstract:
    A distinct characteristic of legged locomotion is its periodic nature. This periodic motion, in the form of a periodic orbit, has been the target of many walking and running control strategies. The spring loaded inverted pendulum (SLIP) has become a popular model of sagittal plane locomotion, exhibiting behavior characteristic of...

  • Reduced order modeling of legged locomotion in the horizontal plane

    Creator:
    Wickramasuriya, Gamika Arun
    Abstract:
    Sprawled-posture insects exhibit a remarkable ability to rapidly run in a stable manner over complex terrain, a feat that has yet to be equaled by man-made legged robots. Recent experimental results suggest that these insects may employ a hierarchical control structure, in which locomotion performance emerges from a combination of...

  • A performance comparison of chainsaw bar lubricants

    Creator:
    Suryan, Levi J.
    Abstract:
    Chainsaws, an indispensable tool for modern forestry operations, rely on bar lubricant to prevent rapid wear of the chain and bar. Choice of bar lubricant must balance performance, cost, and biological impact. Many bar lubricants are available, but little published work exists that conclusively ranks the performance of these choices....

  • Synthetic Lubricant Performance in Enclosed Gearbox Applications at Extreme Temperature

    Creator:
    Marr, Carter J.
    Abstract:
    The goal of this paper is to evaluate how synthetic lubricants perform in an enclosed gearbox application when compared with a proven mineral oil. This is in an effort to improve gearbox efficiency with the desired effect of lower emissions from of improved energy output from power generation. Four liquid...

  • Learning approaches for the early detection of kickback in chainsaws

    Creator:
    Arnold, Drew D.
    Abstract:
    Among the many safety hazards facing chainsaw operators, the phenomenon known as kickback is the most dangerous. Kickback occurs when the chain at the tip of the chainsaw is caused to stop abruptly, and transfers the energy of the cutting chain to motion of the saw. The saw will rotate...

  • Dynamics and stability of lateral plane locomotion on variable inclines

    Creator:
    Bonnono, Scott A.
    Abstract:
    An actuated, bipedal model is developed to investigate lateral plane locomotion dynamics and stability on inclines. Both the point mass case and rigid body case are considered. Variations in the force-free leg length are determined via inverse dynamics to explicitly and implicitly match prescribed lateral and fore-aft force profiles, respectively....
