  • 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...

  • Synthesis and evaluation of PEO-coated materials for microchannel-based hemodialysis

    Creator:
    Heintz, Keely
    Abstract:
    The marked increase in surface-to-volume ratio associated with microscale devices for hemodialysis leads to problems with hemocompatibility and blood flow distribution that are more challenging to manage than those encountered at the conventional scale. In this work, stable surface modifications with pendant polyethylene oxide (PEO) chains were produced on polycarbonate...

  • Alternative design considerations for a wave energy converter : a sustainability approach

    Creator:
    Collins, Erin
    Abstract:
    As the negative impacts of a fossil fueled electricity market are becoming more prevalent and destructive, the necessity for alternative energy techniques increases as well. However, before commercial implementation is underway, these alternatives must be assessed from three important perspectives: environmentally, economically, and socially, which are known as the three...

  • Incremental Forming of Polymers at Room Temperature

    Creator:
    Davar Panah, Mohammad Ali
    Abstract:
    Single Point Incremental Forming (SPIF) is a forming process in which a fully clamped sheet is formed by a hemispherical ended tool that moves along a predefined 3D toolpath. The sheet is formed in a series of local deformations to reach its desired shape. Double Sided Incremental Forming (DSIF) includes...

  • Uplift capacity and displacement of helical anchors in cohesive soil

    Creator:
    Young, Jessica
    Abstract:
    Helical anchors are a type of deep foundation element that can be installed quickly in almost any location and can accept the immediate application of operational loads. The use of helical anchors has expanded in recent decades from its established application in the power transmission industry to more traditional civil...

  • Cooling rate limitations in the diffusion bonding of large microchannel arrays

    Creator:
    Lingam, Gopi K.
    Abstract:
    A significant barrier to the diffusion bonding of large (i.e. 600 mm) microchannel devices is the large capital investment required to setup production. This large capital investment extends from long heating and cooling cycles leading to poor production capacities. Empirical studies in industry have shown that cooling rate is limited...

  • Materials and process design for powder injection molding of silicon nitride for the fabrication of engine components

    Creator:
    Lenz, Juergen H. (Juergen Herbert)
    Abstract:
    A new material system was developed for fabricating the combustion engine of an unmanned aerial vehicle. The material system consisted of a mixture of nanoscale and microscale particles of silicon nitride. Magnesia and yttria were used as sintering additives. The powders were mixed with a paraffin binder system. The binder-powder...

  • Utilizing smart manufacturing information in a job shop to support job selection and processing speed decisions

    Creator:
    Houck, Christopher
    Abstract:
    Creating schedules for the job shop manufacturing system is an extremely difficult task. Although researchers have devoted a lot of attention to generating optimal solutions, these solutions are static, thus they do not update as random events occur that disrupt the system. As smart manufacturing has grown, researchers have been...

  • Medical diagnosis : a functional model and diagnostic aid

    Creator:
    Zolfaghari, Kiumars
    Abstract:
    Improving the quality of the medical system has always been of great importance but has not always made the largest advances. A significant percentage of medical errors are due to wrong, missed, or delayed medical diagnosis. Diagnostic errors are among the most preventable categories of medical errors, but when an...

  • Dividing Complex Parts into Multiple Pieces for Advanced Joining and Additive Manufacturing

    Creator:
    Massoni, Brandon R.
    Abstract:
    Poor material utilization is inherent to conventional manufacturing processes, leading to high material waste and machining times. Additive manufacturing processes attempt to solve this issue by allowing production of near-net shapes, but the processes may be too expensive or infeasible. By leveraging both processes in a single part, the waste...
