  • Wind turbulence input model for horizontal axis wind turbines

    Creator:
    Lin, Shuh-ren
    Abstract:
    In order to estimate wind turbine residL2;characteristics in the presence of atmospheric turbulence, the important atmospheric sources for the force excitations felt by the wind turbine system must be identified and characterized. The goal of this research is to develop the wind turbulence input model for horizontal axis wind turbines....

  • Stochastic analysis of a nonlinear ocean structural system

    Creator:
    Lin, Huan
    Abstract:
    Stochastic analysis procedures have been recently applied to analyze nonlinear dynamical systems. In this study, nonlinear responses, stochastic and/or chaotic, are examined and interpreted from a probabilistic perspective. A multi-point-moored ocean structural system under regular and irregular wave excitations is analytically examined via a generalized stochastic Melnikov function and Markov...

  • Parametric uncertainties in reliability analysis of bridge structures

    Creator:
    Hamutcuoglu, Osman Murat
    Abstract:
    Probability-based reliability methods have placed an increased emphasis on realistic simulation of structural behavior in bridge engineering. Uncertainty is present in every aspect of structural analysis. Aleatory uncertainties in the loading and load-carrying capacities, and epistemic uncertainties in mathematical idealization of bridge systems are the major contributors to uncertain structural...

  • Nonlinear adaptive control of highly maneuverable high performance aircraft

    Creator:
    Cho, Sul
    Abstract:
    This thesis presents an effective control design methodology using a one-step-ahead prediction adaptive control law and an adaptive control law based on a Lyapunov function. These control law were applied to a highly maneuverable high performance aircraft, in particular, a modified F/A-18. An adaptive controller is developed to maneuver an...

  • Design, analysis and evaluation of bridge superstructures for live loads

    Creator:
    Turan, O. Tugrul
    Abstract:
    Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...

  • Derivation and automatic generation of Kane's dynamical equations for mechanical manipulators

    Creator:
    Nie, Tinglin
    Abstract:
    To design and precisely control a manipulator requires developing an efficient dynamic model of the system. The present work demonstrates how this can be accomplished by employing Kane's dynamical equations. First, a detailed manual derivation of the equations of motion for a particular robot is presented in such way that...

  • Application of controlled thermal expansion in diffusion bonding for the high-volume microlamination of MECS devices

    Creator:
    Pluess, Christoph
    Abstract:
    Diffusion bonding has been widely used within microlamination architectures for the fabrication of Micro Energy and Chemical Systems (MECS). MECS are microsystems with the ability to process bulk amounts of fluid within highly-parallel microchannel arrays capable of accelerated heat and mass transfer. Thus far, diffusion bonding of the microchannel arrays...

  • A study of compression loading of composite laminates

    Creator:
    Berbinau, Pierre J.
    Abstract:
    The compressive behavior of continuous fiber composites is not as well understood as their tensile behavior because research and industrial applications have until recently focused on the latter. Furthermore, most theoretical and experimental studies on the compression of composites have examined the case of unidirectional specimens with fibers along the...
