  • Designing a passenger lift and transfer device using 3D modeling and kinematic simulation techniques

    Creator:
    Koshti, Sushim
    Abstract:
    Transportation plays such an important role in daily living that, without it, a person might be totally homebound. The nation’s air travel system for persons with disabilities is an area of substantial dissatisfaction, with both passengers and the airline industry recognizing the need for improvement. One of the major concerns...

  • Engineering analysis of forces created in two tree intermediate supports during multi-span logging

    Creator:
    Fodge, Francis W.
    Abstract:
    An analysis of forces on two tree intermediate supports is presented. The analysis is in two parts: The maximum force that the support jack will experience. The movement and forces created in the two tree support by the skyline and carriage. The maximum force on the support jack occurs when...

  • Improved efficiency in medium-power flyback converters

    Creator:
    Ruttanapaibooncharoen, Surin
    Abstract:
    Switch-mode power supplies (SMPS's) not only convert energy, they also consume it. Typical operational efficiencies are approximately 25 to 60% for linear power supplies, and approximately 50-90% for switching power supplies. This means that products whose end-use electronics are dc, such as televisions and DVD players, could consume 50% less...

  • A high power emulation of a wind farm

    Creator:
    Lalla, Chelsea
    Abstract:
    As more wind farms are connected to the grid, the variable nature of wind energy begins to influence grid stability. Energy storage could help smooth the variable nature of wind energy. Laboratory demonstration and exploration of the interaction between different energy storage devices and wind energy could help improve and...

  • A method of selection of cable harvesting machines for Vermont

    Creator:
    Stirler, Dennis John
    Abstract:
    There is much interest in the State of Vermont in cable harvesting. Since there are no time studies available for cable harvesting with various machines in Vermont, it is necessary to arrive at production and cost levels by a different method. The method chosen for this paper is made up...

  • A novel control design for a wave energy converter

    Creator:
    Schacher, Alphonse A.
    Abstract:
    Ocean wave energy is rapidly becoming a field of great interest in the world of renewable energy. Significant advancements in design and technology are being made to make wave energy a viable alternative for our growing energy demands. The two major hurdles for ocean wave energy to make a significant...

  • A force plate for measuring contact forces during dependent transfers onboard aircraft

    Creator:
    Schafer, Christopher A.
    Abstract:
    The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...

  • Evaluation of the performance of a taut-moored dual-body direct-drive waveenergy converter through numerical modeling and physical testing

    Creator:
    Elwood, David E.
    Abstract:
    With energy prices rising and increasing concern about the influence of fossil fuels on climate change, wave energy systems are on the verge of commercial implementation. These first generation wave energy converters utilize either pneumatics or hydraulics to convert the mechanical energy of waves into electricity. For the last several...

  • Planning Under Uncertainty for Unmanned Aerial Vehicles

    Creator:
    Skeele, Ryan
    Abstract:
    Unmanned aerial vehicle (UAV) technology has grown out of traditional research and military applications and has captivated the commercial and consumer markets, showing the ability to perform a spectrum of autonomous functions. This technology has the capability of saving lives in search and rescue, fighting wildfires in environmental monitoring, and...
