  • A Unit Manufacturing Process Characterization Methodology and Supporting Terminology for Sustainable Manufacturing Assessment

    Creator:
    Garretson, Ian C.
    Abstract:
    Manufacturing industry drives economic activity and growth around the world, but manufacturing activities consume large amounts of material, energy, and labor resources. Therefore, the impacts of manufacturing need to be accounted for and reduced. Direct benefits of manufacturing are products and income, which, in turn, influence the lives of people...

  • Advanced Computational Modeling Methods for Floating Offshore Wind Systems

    Creator:
    Devin, Michael C.
    Abstract:
    Floating offshore wind energy is anticipated to become a competitive source of renewable energy by the late 2020s, but the industry must reduce costs and uncertainties associated with the technology to do so. Identifying solutions to these problems frequently relies on computational modeling, which presents technical shortcomings limiting the versatility...

  • Percent Area Visual Obscuration of F1 Racecar Canopies

    Creator:
    Jennings, Alex
    Abstract:
    Considering human product interactions early and often in the engineering design process may improve product quality, facilitate user safety, reduce time to market, decrease or eliminate the need for costly physical prototypes, and reduce expensive late stage design changes. Currently, F1 race cars do not include a cockpit canopy to...

  • Pre-Prototyping Framework: An Early Design Prototyping Methodology for Human-Centered Products and Workplaces

    Creator:
    Ahmed, Salman
    Abstract:
    Prototyping is a crucial step in product design and development, but it is also known as the highest sunk cost. The top 20 Research and Development (R&D) department spends 142 billion dollars, yet 40 to 46 percent of this money goes into developing products that cannot even make to the...

  • Development of a Cartesian-grid-based solver for an oscillatory boundary layer over a rough wall

    Creator:
    Skitka, Joseph M.
    Abstract:
    Predominant models for predicting rates of sediment transport face acute shortcomings when applied to coastal boundary layers. This is due to a neglect of the web of stochastic variables governing the rate of sediment dislodgement. While stochastic models do exist, the parametric extent of their validity tends to be limited,...

  • 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...

  • Achieving Transparency in Human-Collective Systems

    Creator:
    Roundtree, Karina A.
    Abstract:
    Collective robotic systems are biologically-inspired and exhibit behaviors found in spatial swarms (e.g., fish), colonies (e.g., ants), or a combination of both (e.g., bees). Collective robotic system popularity continues to increase due to their apparent global intelligence and emergent behaviors. Many applications can benefit from the incorporation of collectives, including...

  • Development of Cu-based Thin Films for Optoelectronic Applications

    Creator:
    Angelos, Gregory S.
    Abstract:
    CIGS and CdTe based commercial thin-film solar cells (TFSCs) require an absorber thickness greater than 2 µm and 4 µm, respectively, to adequately absorb the solar spectrum. To efficiently extract photoexcited electrons, these TFSCs require relatively defect-free absorbers with high-minority carrier mobility (> 100 cm2V−1s−1) and long lifetime (> 10...

  • Application of digital image correlation in material parameter estimation and vibration analysis of carbon fiber composite and aluminum plates

    Creator:
    Chuang, Chih-Lan Jasmine
    Abstract:
    Identifying material parameters in composite plates is a necessary first step in a variety of structural applications. For example, understanding the material parameters of carbon fiber composite is important in investigating sensor and actuator placement on micro-air-vehicle wings for control and wing morphing purposes. Knowing the material parameters can also...

  • Evaluation of Heat and Mass Transfer Models for Sizing Low-Temperature Kalina Cycle Microchannel Condensers

    Creator:
    Fronk, Brian M. and Zada, Kyle R.
    Abstract:
    Waste heat driven ammonia/water Kalina cycles have shown promise for improving the efficiency of electricity production from low-temperature reservoirs (T < 150 °C). However, there has been limited application of these systems to utilize widely available, disperse, waste heat streams for smaller scale power production (1–10 kWe). Factors limiting increased deployment of these...
