  • Sources of flow maldistribution in microreactor-assisted synthesis of ceria nanoparticles

    Creator:
    Tseng, Chih-Heng
    Abstract:
    Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...

  • Investigation of Thermal Degradation in Structural Alloys for Nuclear Power Systems

    Creator:
    Teng, Fei
    Abstract:
    The thermal degradation of structural materials is considered to be a key factor for evaluating the lifetime of current nuclear power plants. Ni-based and Fe-based alloys, such as 690, 625, 304, and 316, are widely used in nuclear industry as structural components due to the extraordinary corrosion resistance and mechanical...

  • Predicting deep water breaking wave severity

    Creator:
    Hovland, Justin
    Abstract:
    Ocean Wave Energy Converters (WECs) operating on the water surface are subject to storms and other extreme events. In particular, high and steep waves, especially breaking waves, are likely the most dangerous to WECs. A method for quantifying the breaking severity of waves is presented and applied to wave data...

  • Smooth Trajectory Generation for Machine Tools and Industrial Robots

    Creator:
    Tajima, Shingo
    Abstract:
    This thesis presents accurate and time-optimal smooth reference trajectory generation techniques for manufacturing equipment such as high-speed machine tools (MT) and industrial robots (IR). Typical machining tool-paths for MTs and IRs are defined as a series of discrete linear moves. Although Point-to-Point (P2P) feed motion can be generated by interpolating...

  • An information modeling framework and desktop application to compose unit manufacturing process models for sustainable manufacturing assessment

    Creator:
    Smullin, Matteo M.
    Abstract:
    The demand from consumers for more sustainable products, and the need to comply with government regulations motivates manufacturers to evaluate their operations for opportunities to reduce environmental impact and improve economic competitiveness. Manufacturers have actively improved the sustainability performance of their products through the use of sustainability assessment methods and...

  • Sustainability assessment during early product development : the manufacturing case and the use case

    Creator:
    Seyedmahmoudighomi, Seyedhamed
    Abstract:
    The research explored in this thesis helps provide a better understanding of efforts that have been undertaken to more precisely calculate environmental impacts and human health risks, such as energy consumption, carbon footprint, and toxicity, to support environmental sustainability assessment of products. The work is comprised of two research objectives,...

  • Privacy-Sensitive Robotics

    Creator:
    Rueben, Matthew R.
    Abstract:
    This dissertation focuses on personal privacy in human-robot interaction, which we call "privacy-sensitive robotics." Our understanding of "privacy" is very broad, including not just information privacy but also physical, psychological, and social privacy. We begin by surveying the scholarly literature on privacy and talking about why it applies to interactions...
