  • Group scheduling in electronics manufacturing with integration of internal and external setup times

    Creator:
    Yazdani Sabouni, Mohammad Taghi
    Abstract:
    This research considers a combinatorial optimization scheduling problem in the assembly of printed circuit boards (PCBs) in electronic manufacturing. For the first time in this research, the preparation process, which is typically called kitting operation, is paid attention to and is performed along with the assembly operation, described in this...

  • Sequencing using Surrogate Values on Paced Assembly Lines

    Creator:
    Alfaiz, Faisal S.
    Abstract:
    On a paced mixed-model assembly line various product variants are assembled in the same sequence of serially arranged workstations that make up the line. The goal is to assemble the products with the lowest cost possible while meeting demand requirements. Since the work content of product variants may differ at...

  • The dynamic shear moduli of blubber for selected large whale species

    Creator:
    Summers, Michael P.
    Abstract:
    Whale blubber is the insular tissue layer located between the dermis and the superficial fascia layer which sheathes the whale's musculature. It is made up of a lipid matrix ramified with strong, structural collagen and elastic fiber bundles, but little is known of its mechanical properties. Knowing these properties adds...

  • 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...

  • Light soaking in metal-halide perovskites

    Creator:
    Watts, C. Lowell
    Abstract:
    Despite climate change requiring the cutback of fossil fuel consumption, the world continues to increase its energy demands each year. To meet the ambitious goals outlined during the Paris Agreement in 2015, which set a goal to limit global warming to 1.5°C [1], changes in energy production methods are necessary....

  • Study of the Effects of Chain Whip Length and Bar Length on the Characteristics of Chain Shot

    Creator:
    Shannon, Eric R.
    Abstract:
    Timber harvesters are high powered industrial grade rigs used to fell, delimb, and cut to size large trees. Hydraulic motors power sprockets that drive chains around a guide bar that get extended through logs during cuts. As technological advances allow for higher speeds a phenomenon called “chain shot” has...

  • An investigation into the electrochemical removal of unwanted residual material protrusions from parts

    Creator:
    Bingham, Bruce C.
    Abstract:
    Manuscript I: The removal of residual casting material from gating has traditionally been performed by abrasive grinding techniques. However, high amounts of belt wear can occur when working with high strength alloys, especially those typically seen in the aerospace industry. An alternative machining process called electrochemical machining (ECM) uses electrolysis...

  • The Applicability of Linear Elastic Fracture Mechanics to Compressive Damage of the Carbon Fiber Reinforced Plastic Matrix

    Creator:
    Carpenter, Kevin T.
    Abstract:
    With the widespread replacement of aluminum with composite materials, particularly in aircraft structures, the lack of comprehensive understanding of these materials is unsettling. The complex nature of these materials, with respect to isotropic aluminum, makes the prediction of their mechanical response equally complex. The failure of carbon fiber reinforced plastic...

  • 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....

  • Design, analysis, and validation of composite c-channel beams

    Creator:
    Koski, William C.
    Abstract:
    A lightweight carbon fiber reinforced polymer (CFRP) c-channel beam was previously designed using analytical theory and finite element analysis and subsequently manufactured through a pultrusion process. Physical testing revealed the prototype did not meet the bending and torsional stiffness of the beam model. An investigation revealed that the manufactured prototype...
