  • Mechanical design history content : the information requests of design engineers

    Creator:
    Kuffner, Tom A.
    Abstract:
    This thesis reports on research conducted to determine the information which should be included in a mechanical design history. This is part of a larger research effort aimed at developing a computer tool for storing and replaying mechanical design history information. Three question-asking protocols were conducted to determine what information...

  • 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...

  • Model based visualization of vibrations in mechanical systems

    Creator:
    Jitpraphai, Thanat
    Abstract:
    To visualize vibrations in mechanical systems, e.g., machine tools, their movements are measured by means of suitable sensors. The signals from these sensors are processed and displayed as animated pictures on a computer screen. Accelerometers have been chosen as the most suitable sensors for this purpose. Their main advantages include...

  • 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...

  • A study of thermal stratification in the cold legs during the subcooled blowdown phase of a loss of coolant accident in the OSU APEX Thermal Hydraulic Testing Facility

    Creator:
    Wachs, Daniel M.
    Abstract:
    The phenomena of interest in this work is the thermal stratification which occurs during the early stages of a loss of coolant accident (LOCA) in the OSU APEX Thermal Hydraulic Test Facility, which is a scaled model of the Westinghouse AP600 nuclear power plant. Thermal stratification has been linked to...

  • Computer assisted design of planar workholders

    Creator:
    Chancharoen, Ratchatin
    Abstract:
    There are many situations in which contact between two bodies is at a single point so there can be no tensile (force). This form of contact only provides a single degree of restraint, and is defined as a unidirectional point contact. The analysis of Reuleaux shows that four suitably placed...

  • An experimental/analytical investigation of buoyant jets in shallow water

    Creator:
    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...

  • An Engineering Decision Support System (EDSS) with alternative-criterion pair evaluations

    Creator:
    Herling, Derald E.
    Abstract:
    An Engineering Decision Support System, EDSS, was developed using Bayesian mathematics which incorporates knowledge and confidence components observed in alternative-criterion pair decision making. The separation of knowledge and confidence has been previously unaccounted for in decision-making methods. EDSS provides decision support to individuals or teams which must make choices between...

  • Laminar microchannel cooling of integrated circuits

    Creator:
    Lienau, Jeffrey Jay
    Abstract:
    Liquid cooled, laminar microchannel heat sinks were earlier proposed by Tuckerman for cooling high heat generating integrated circuits and high power microwave generation systems using photoconductive switches. A method of computationally analyzing the heat sinks is presented which produces the desired temperature and velocity distributions within the heat sinks. The...
