  • Static and dynamic testing of a recumbent bicycle's suspension components, and design of a damping coefficient-spring constant test machine

    Creator:
    Metaxides, Evangelos
    Abstract:
    The purpose of this study is to provide the necessary technical background and data for the development of a suspension system for a recumbent bicycle. For this reason, the customer requirements-design criteria for the development of the suspension system were set, and several static and dynamic tests were conducted on...

  • Vortex Generator Flow Control for an Upper-Surface Blown Aircraft Wing with an Extended Coanda Flap

    Creator:
    Kelly, Bryan R.
    Abstract:
    Integrated Distributed Electric Augmented Lift (IDEAL) applies upper-surface blowing in a novel way using an array of electric ducted fans (EDFs) to achieve electric short take-off and landing to meet the growing need for urban air transportation. Additional research on the use of vortex generators (VGs) to reduce flow separation...

  • SketchPad for Windows : an intelligent and interactive sketching software

    Creator:
    Gulur, Sudheendra S.
    Abstract:
    The sketching software developed in this thesis, is aimed to serve as an intelligent design tool for the conceptual design stage of the mechanical design process. This sketching software, Sketch Pad for Windows, closely mimics the traditional paper-and-pencil sketching environment by allowing the user to sketch freely on the computer...

  • 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...

  • An object oriented representation for mechanical design based on constraints

    Creator:
    McGinnis, Brian D.
    Abstract:
    A representation for the process of mechanical design, along with its computer implementation is presented and discussed. The representation consists of three fundamental concepts: design objects, constraints, and decisions. The design objects are the structures with which the physical artifacts of the design are described. A design object consists of...

  • Stakeholder evaluation of market based approaches towards managing the adverse impacts of commercial fishing on the marine environment

    Creator:
    Swart, Brycen
    Abstract:
    Over fishing, by-catch of non-target fish species, marine mammals, seabirds, and damage to benthic habitats remain serious problems in fisheries management. Management methods based on traditional command and control (CAC) approaches may meet with initial successes yet additional progress is often marginal, requiring managers to implement additional regulations to achieve...

  • Filling a rough-mill cutting order using a fuzzy logic controller

    Creator:
    Anderson, James D.
    Abstract:
    Because of their high cost, reducing the number of boards used to fill an order of dimension parts is an important goal in a lumber rough mill. FLCO (Fuzzy Logic Cutting Order) is a computer program that achieves this goal. Using the concepts of fuzzy logic control, FLCO provides a...

  • EDLAN, an educational local area network

    Creator:
    Yu, Hua
    Abstract:
    EDLAN is a simple, inexpensive local area network suitable for educational applications. In EDLAN, a number of personal computers are connected through an RS-485 global bus which carries the data transmission among the computers. CSMA/CD protocol is used to control the access of the global bus. The communications are controlled...

  • Creep of Gr/BMI composite laminates in compression

    Creator:
    Tyagi, Sanjeev R.
    Abstract:
    The main source of the time-dependent behavior of fiber-reinforced composites is their polymeric matrix, which causes concerns about their long term durability. Although for composites where organic fibers such as Graphite are used, the fibers are also a contributing factor. A composite material may exhibit an appreciable amount of creep,...

  • An evaluation of the use of tarif tables in second growth Douglas-fir

    Creator:
    Marshall, David D.
    Abstract:
    The Washington State Department of Natural Resources' Comprehensive Tree-Volume Tarif Tables are a set of preconstructed local volume tables. This can increase "on plot" efficiency since only diameters are necessary to obtain volumes after the proper table for the given diameter/height relationship is accessed. The tables are accessed and indexed...
