  • Robustness in a distributed storage server for engineering design data with versions

    Creator:
    Ecklund, Denise J.
    Abstract:
    Traditional database management systems have been deemed unsuitable for use in the Computer Aided Engineering environment Object-oriented data models with project management features have been proposed as an alternative. The Distributed Hypothetical Storage System is intended to serve as the underlying storage mechanism for an object-oriented data model. The storage...

  • 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...

  • 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...

  • 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...

  • Development of a real-time digital computing facility in chemical engineering

    Creator:
    Fukui, Stanley Chikashi
    Abstract:
    An advanced laboratory interfacing capability was developed for the Real-Time Digital Computer Laboratory in the Chemical Engineering Department. A stationary interfacing unit located beside the computer mainframe and two small remote units were designed, developed and thoroughly tested. These interfacing units permit experiments with a wide variety of analog and...

  • Computer aided tolerance analysis and process selection for AutoCAD

    Creator:
    Pamulapati, Sairam V.
    Abstract:
    The fundamental objective of a design engineer in performing tolerance technology is to transform functional requirements into tolerances on individual parts based on existing data and algorithms for design tolerance analysis and synthesis. The transformation of functional requirements into tolerances must also consider the existing process capabilities and manufacturing costs...

  • A computer-assisted qualitative data analysis framework for the engineering management domain

    Creator:
    Saeedi, Amirali
    Abstract:
    Qualitative data analysis (QDA) is a time consuming and, potentially unreliable research activity. In qualitative research, a number of tasks must be repeated for every new research case, even if each case is closely related or is in the same area of study. Existing QDA applications provide users with a...

  • 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...

  • Nodal methods for calculating nuclear reactor transients, control rod patterns, and fuel pin powers

    Creator:
    Cho, Byung-Oh
    Abstract:
    Nodal methods which are used to calculate reactor transients, control rod patterns, and fuel pin powers are investigated. The 3-D nodal code, STORM, has been modified to perform these calculations. Several numerical examples lead to the following conclusions: (1) By employing a thermal leakage-to-absorption ratio11 (TLAR) approximation for the spatial...

  • Urban military operation mobility model

    Creator:
    Kang, Ho Sung
    Abstract:
    A Mobile Ad-hoc NETwork (MANET) is collection of wireless mobile nodes without a network infrastructure or centralized administration. Although MANETs can be used in many applications, such as mobile Internet, military communication, and disaster relief networks, a number of challenges remain. These include routing, medium access control, security, scalability, energy...
