  • Integration of vapor-solid grown ZnO nanowires through dielectrophoresis

    Creator:
    Ng, Vi-Vie
    Abstract:
    Work on individually constructed devices has demonstrated that nanowires (NWs) offer great promise for applications such as sensing and optoelectronics. Despite this work, reliable large scale alignment and integration of these individual nanostructures into a lithographically defined process remains a challenge. Dielectrophoresis (DEP) is a promising alignment method in which...

  • An aeroelastic analysis of the Darrieus wind turbine

    Creator:
    Meyer, Edward Earnest
    Abstract:
    The stability of small oscillations of the troposkeinshaped blade used on Darrieus wind turbines is investigated. The blade is assumed to be attached to a perfectly rigid rotor shaft and spinning in still air. Linear equations of motion are derived which include the effects of in-plane, out-of-plane, and torsional stiffness,...

  • Low power design techniques for high speed pipelined ADCs

    Creator:
    Lingam, Naga Sasidhar
    Abstract:
    Real world is analog but the processing of signals can best be done in digital domain. So the need for Analog to Digital Converters(ADCs) is ever rising as more and more applications set in. With the advent of mobile technology, power in electronic equipment is being driven down to get...

  • Initial state estimation for a gun launched projectile in a spatially varying magnetic field

    Creator:
    Chawla, Feni
    Abstract:
    Smart weapons promise to provide leap ahead capability with regard to accuracy and engagement range for medium and large caliber projectiles. One of the most critical components of a smart weapon system is its sensor suite that provides position, orientation, and velocity information as the projectile flies down range so...

  • Deformation-based seismic design models for waterfront structures

    Creator:
    Yang, Dong-Shan
    Abstract:
    Recent experience demonstrates that waterfront structures are vulnerable to earthquake damage. The poor seismic performance of these facilities has been primarily due to liquefaction of backfill and/or foundation soils and the lack of seismic design standards for waterfront structures. The seismic performance of waterfront structures is a key issue in...

  • Design considerations for a miniature atmospheric engine with a magnet-actuated autonomously-reciprocating in-cylinder regenerator for portable power production

    Creator:
    Yarger, David J.
    Abstract:
    Driven by the need for high energy-density power sources, demand has stimulated the development of small-scale engines. A small-scale engine with a fuel supply could replace batteries and utilize higher energy-density liquid hydrocarbon fuels; such an advance could deliver a new age of portable devices. Currently, operable small-scale engines exist;...

  • Dynamic modeling, control and linear theory of a projectile equipped with a rotating internal part

    Creator:
    Frost, Geoffrey W.
    Abstract:
    Dynamic modeling of the atmospheric flight mechanics of a projectile equipped with an uncontrolled internal rotating disk is investigated and a modified projectile linear theory is established. It is shown through modeling of this type of projectile that several coefficients of the epicyclic dynamics are altered, leading to changes in...

  • A 10 bit algorithmic A/D converter for a biosensor

    Creator:
    Rengachari, Thirumalai
    Abstract:
    This thesis presents a novel algorithmic A/D converter to be used in a biosensor. The converter is capable of a conversion rate of 1.5 bits/phase and hence the required conversion time is reduced. The proposed architecture is analyzed for non-ideal effects and compared with existing algorithmic A/D architectures. The converter...

  • Optimal design of traction drive continuously variable transmissions

    Creator:
    Lim, Kyoung Ho
    Abstract:
    The optimal design technique for minimum power loss in traction drive continuously variable transmissions is developed. The mathematical model is developed to evaluate the traction force and torque in traction drive contact. Kinematic analysis of general traction drive contact is conducted to find the best configuration for minimum power loss....
