  • An empirical study on the process of mechanical design

    Creator:
    Stauffer, Larry A.
    Abstract:
    An information processing model of the problem-solving performance of mechanical designers is presented for four design tasks: conceptual assembly design, layout component design, detail component design, and catalog selection. These tasks are organized into six kinds of segments called episodes, which describe the goal structure of the designer while performing...

  • A computer-based design history tool

    Creator:
    Chen, Ai-hua
    Abstract:
    In current practice, design documentation often fails to support the activities of design understanding, communication, and redesign. A Design History Tool has been developed to improve current design documentation. This tool is a computerized design history that represents and plays back important information generated during the process of designing a...

  • The design capture system : capturing back-of-the-envelope sketches

    Creator:
    Hwang, Teng-shang
    Abstract:
    A system which allows the computer to capture sketches made by a mechanical designer is described. The system not only recognizes basic features as they are sketched, but it also reasons the spatial relationships between features and builds a high level abstract representation (feature model) of the artifact. The temporal...

  • Experimental and analytical characterization of bidirectional reflectance data for engineering materials

    Creator:
    Zaworski, Joseph Robert
    Abstract:
    Bidirectional reflectance is a fundamental property used for the analysis of radiative heat transfer. It is a form of reflectivity in which the spectral and directional dependencies of both the beam incident on a surface and the beam reflected from the surface are specified. A new system has been designed...

  • Data-Driven Environmentally Sustainable Product Design: A Shift Toward Increased use of Sustainable Design Activities in the Early Design Phase

    Creator:
    Ferrero, Vincenzo J.
    Abstract:
    Modern product design drives the boundaries of innovation by encompassing complex Design-for-X objectives, and the inclusion of multidimensional stakeholders. This growing complexity in product design has left design teams unequipped, as classical design theory is bounded by designer experience, expertise, and cognition. One novel approach to tackling product complexity is...

  • Characterizing Linkages Between the Climate, Cryosphere, and Impacts on Run-of-River Hydropower in Data-Sparse Mountain Environments

    Creator:
    Mosier, Thomas M.
    Abstract:
    In many regions of the world, a significant portion of the surface water originates in mountain headwaters where the timing and magnitude of streamflow is largely dictated by the seasonal storage of precipitation as snowpack and long-term storage as glaciers. Accumulation, persistence, and melt of snow and ice are functions...

  • Multi-modal sensing data fusion for machining and additive manufacturing

    Creator:
    Fu, Xianzhe
    Abstract:
    With the increased demand for high-quality products, reliable and robust process monitoring has become a key capability for modern manufacturing systems. Through sensors installed in the machinery, the real-time information was measured to assess the state of the processes. The measured data can be used to infer the mechanical, material,...

  • Empirical Characterization and Data-Driven Optimization of Water-Energy Systems

    Creator:
    Elhashimi, Mohammed A.
    Abstract:
    The accelerated development in water-energy systems calls for advanced modeling and optimization tools to improve technologies’ performance. Water desalination is a manifestation of water-energy system that is challenged by different operational constraints. The scarcity and uneven distribution of freshwater around the world makes water desalination an indispensable process to address...

  • Compact integrated microchannel combustor, recuperator and heat exchanger For hydrogen storage applications

    Creator:
    Ghazvini, Mohammad
    Abstract:
    A novel microscale combustor-heat exchanger (μCHX) for hydrogen storage applications is presented in this dissertation. The design of the μCHX is motivated by its application to two particular systems for automotive use- those that utilize metal hydrides (MH) and cryo-adsorbents (CA) to store hydrogen. Thermal energy needs to be supplied...

    Hsiao, Entsung
    Abstract:
    This thesis presents the results of an experimental and analytical study of single-port buoyant turbulent jets discharged into shallow water. The experimental results include the measured downstream dilution, centerline concentration and trajectory. Independent parameters considered were Froude number, submerged depth, discharge angle and velocity ratio. Results indicate that decreasing the...
