    Fabrication of Three-Dimensionally Independent Microchannels Using a Single Mask Aimed at On-Chip Microprocessor Cooling 

    Gantz, Kevin Francis (Virginia Tech, 2007-11-28)
    A novel fabrication process is presented which allows for three-dimensionally independent features to be etched in silicon using SF6 gas in a deep reactive ion etcher (DRIE) after a single etch step. The mechanism allowing ...

    The Design, Fabrication, and Modeling of a Piezoelectric Linear Motor 

    Vaughan, Mark Edward (Virginia Tech, 2001-12-19)
    The focus of this research was to create a linear motor that could easily be packaged and still perform the same task of the current DC motor linear device. An incremental linear motor design was decided upon, for its ...

    Lateral and Posterior Dynamic Bending of the Mid-Shaft Femur: Fracture Risk Curves for the Adult Population 

    Kennedy, Eric Allen (Virginia Tech, 2004-04-22)
    The purpose of this study was to develop injury risk functions for dynamic bending of the human femur in the lateral-to-medial and posterior-to-anterior loading directions. A total of 45 experiments were performed on human ...

    The Music Muse 

    Wilson, Leslie (Virginia Tech, 1996-11-01)
    Ever wonder why two people can sing the same note with the same loudness, but sound completely different? Middle C is middle C no matter who sings it, yet for some reason Lucianno Pavarotti1s middle C sounds richer and ...

    Transient Model of Heat,Mass,and Charge transfer as well as Electrochemistry in the Cathode Catalyst Layer of a PEMFC 

    Genevey, Daniel Bruno (Virginia Tech, 2001-12-17)
    A transient model of the cathode catalyst layer of a proton exchange membrane fuel cell is presented. The catalyst layer structure can be described as a superposition of the polymer membrane, the backing layer, and some ...

    Approximations for Nonlinear Differential Algebraic Equations to Increase Real-time Simulation Efficiency 

    Kwong, Gordon Houng (Virginia Tech, 2010-05-05)
    Full-motion driving simulators require efficient real-time high fidelity vehicle models in order to provide a more realistic vehicle response. Typically, multi-body models are used to represent the vehicle dynamics, but ...

    Thermophysical Properties and Microstructural Changes of Composite Materials at Elevated Temperature 

    Goodrich, Thomas William (Virginia Tech, 2009-11-19)
    Experimental methods were developed and used to quantify the behavior of composite materials during heating to support development of heat and mass transfer pyrolysis models. Methods were developed to measure specific heat ...
