  • D₊₊ : Structural Credit Assignment in Tightly Coupled Multiagent Domains

    Creator:
    Rahmattalabi, Aida
    Abstract:
    Autonomous multiagent teams can be used in complex exploration tasks to both expedite the exploration and improve the efficiency. However, use of multiagent systems presents additional challenges. Specifically, in domains where the agents' actions are tightly coupled, coordinating multiple agents to achieve cooperative behavior at the group level is difficult....

  • Acceleration of Long-Range Ordering in NiCrFe Alloys Via Proton Irradiation

    Creator:
    Evered, Cole E.
    Abstract:
    This work explores the hypothesis that proton irradiation is a feasible alternative to simulate accelerated thermal aging for Ni2Cr long-range ordered phase formation within NiCr and NiCrFe alloys. In this study, various model alloys and commercial alloys 690 and 690+P (0.01 wt.% P) were subject to 2 MeV proton irradiation...

  • The Processing and Microstructures of 309L Stainless Steel Clad onto Carbon Steel with Wire-fed Directed Energy Deposition

    Creator:
    Bozeman, Scott C.
    Abstract:
    Directed energy deposition and laser cladding technologies are suitable advanced manufacturing techniques for applying corrosion-resistant claddings to large carbon steel components. In this work, we clad 309L stainless steel wire onto carbon steel substrates and examine the effects of cladding parameters (laser power and travel speed) on metallurgical bonding, composition,...

  • Initial Designs for Improving Conversations for People Using Speech Synthesizers

    Creator:
    Nguyen, Duy M.
    Abstract:
    This thesis aims to determine the impact that Augmentative and Alternative Communication (AAC) devices have on social interactions, and then improves the AAC user experience through a user focus design process. AAC devices enable people who cannot speak to communicate with others. Unfortunately, they are tedious to use and make...

  • Robots Against Infectious Diseases : A Technologically Grounded, Human-Centered Exploration

    Creator:
    Kraft, Kory
    Abstract:
    Robots have the potential to protect health care workers, provide patient care, and ultimately save lives in infectious disease outbreaks. Nevertheless, infectious disease outbreak scenarios present unique technological and social challenges for robotics. This work explores what robots can and should do in the fight against infectious diseases. We present...

  • Exploring the Ductility Minimum of Niobium C103 at Intermediate Temperatures using Triaxial Tensile Specimens

    Creator:
    Wood, Thomas N., II
    Abstract:
    This work explores the mechanical properties of single-phase niobium alloy C103 from room temperature to 600°C for the purpose of expanding safe uses of the material into new applications. The study utilizes a symmetrically notched triaxial tensile specimens to manipulate the internal stress field in order to observe the changes...

  • Heat Treatment Effects on the Mechanical Properties and Microstructure of CPM-M4 Tool Steel

    Creator:
    Fast, Cody P.
    Abstract:
    Variations in heat treatments have significant effects on the microstructure of tool steels. For CPM-M4 tool steel, the changes in microstructure and mechanical properties were observed based off of variations in temperature. Five heat treatments with constant exposure time and variable austenitizing and tempering temperatures were performed on samples of...

  • A shared-autonomy heavy-lift assistive robot for manufacturing

    Creator:
    Finley, Taylor M.
    Abstract:
    Automating pick-and-place operations for large steel castings in a foundry is challenging, particularly from a perception point of view. Accurately estimating the identity and orientation of a given part is an open and complex problem, especially if that part sits in a bin of very similar parts. The problem is...

  • Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

    Creator:
    Bowen, Michael S.
    Abstract:
    Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

    Creator:
    Koziol, Adam
    Abstract:
    The monolithic (plate type) Uranium 10 wt.\% Molybdenum (U-10Mo) fuel system is promising for a variety of applications, most notably for the replacement of highly enriched uranium (HEU) fuels with low enriched uranium (LEU) fuel in United State High Performance Research Reactors (U.S. HPRRs). Phase transformations and secondary phase formation...
