  • Condensation of a zeotropic mixture, R-454C, and its individual components, R-1234yf and R-32, in microfin tubes

    Creator:
    Matty, Ethan P.
    Abstract:
    This work compares the condensation heat transfer and pressure drop for zeotropic refrigerant R-454C and its individual components, R-32 and R-1234yf, in horizontal microfin tubes. One microfin tube has a 4 mm outer diameter, 0.18 mm wall thickness, and a surface area ratio of 1.56. The second tube has a...

  • One Service Robot’s Exploration of Entertainment Methods During COVID-19

    Creator:
    Tsai, Yao-Lin
    Abstract:
    The study focuses on how to use entertainment method approach to prompt people with best practices for COVID safety. During COVID times, there have been many robots deployed in public places such as social distancing enforcer or a robot that provide facial masks, but few investigations have been done to...

  • Integrated forward light scattering as a measure of aerosol mass concentration

    Creator:
    Tomine, Chris Shinya
    Abstract:
    A mathematical model was developed that relates the ratio, R, of two light flux measurements to the mass concentration, m, of the atmospheric aerosol particles between a source of parallel light (e.g., the sun) and the measuring system. R is defined as the ratio of the light fluxes passing through...

  • Microwave sintering of alumina-titanium cermets

    Creator:
    Wrzesinski, Wendell R.
    Abstract:
    The influence of microwave radiation on the fabrication of cermet materials has been investigated for alumina-titanium cermets with compositions ranging from 20 to 80 wt. % titanium. An industrial microwave oven was characterized and adapted to process cermet materials. Physical and mechanical property determinations were made as a function of...

  • Learning-based control and coordination of autonomous UAVs

    Creator:
    Bell, Adam R.
    Abstract:
    Uninhabited aerial vehicles, also called UAVs are currently controller by a combination of a human pilot at a remote location, and autopilot systems similar to those found on commercial aircraft. As UAVs transition from remote piloting to fully autonomous operation, control laws must be developed for the tasks to be...

  • The Design of a Multidisciplinary Capstone Course

    Creator:
    Rust, Nathan R.
    Abstract:
    The end goal of any educational program is to prepare a student for the challenges they will see after completion of their studies. In the realm of engineering, the pinnacle of this occurs during a student’s final Capstone course series, where students are asked to apply their various skills learned...

  • Automated Rapid Manufacturing Feedback for Design Considering Advanced Joining Processes

    Creator:
    Chan, Rothanak
    Abstract:
    As manufacturing advancements continue to develop, designers must be able to consider these technologies during the design process. Unfortunately, many of these new technologies, such as additive and advanced joining, have many nuances that require expert knowledge to effectively apply. Additionally, new design techniques, such as topology optimization, allow users...

  • Lateral pulse jet control of a direct fire atmospheric rocket using an inertial measurement unit sensor system

    Creator:
    Jitpraphai, Thanat
    Abstract:
    Impact point dispersion of a direct fire rocket can be drastically reduced with a ring of appropriately sized lateral pulse jets coupled to a trajectory tracking flight control system. The system is shown to work well against uncertainty in the form of initial off-axis angular velocity perturbations as well as...
