  • Carmichael, Benjamin Daniel (University of Alabama Libraries, 2014)
    The mechanical response of a living cell is notoriously complicated. The complex, heterogeneous characteristics of cellular structure introduce difficulties that simple linear models of viscoelasticity cannot overcome, ...
  • Zargarani, Anahita (University of Alabama Libraries, 2016)
    The goal of this research is to investigate electrical circuits for piezoelectric energy harvesting, and proposing an electrical interface to enhance the output power of a piezoelectric energy harvester. Following this is ...
  • Wu, Molei (University of Alabama Libraries, 2016)
    In the development of powered lower-limb prostheses, providing sufficient power and torque to support amputees’ locomotion is a major challenge, considering prostheses’ weight and size limits. Furthermore, regulating the ...
  • Zheng, Hao (University of Alabama Libraries, 2017)
    The primary purpose of lower extremity prostheses is to restore the locomotive functions of amputees’ lost sections and joints. The objective of this dissertation is to develop energetically active transtibial (TT, also ...
  • Wynn, Logan (University of Alabama Libraries, 2014)
    A flexible, flag-like wind energy harvester made from metallized PVDF material is introduced. A mathematical model for the piezoelectric flag excited by wind flow is developed. The model is validated with experimental ...
  • Kavanaugh, Joshua Stephen (University of Alabama Libraries, 2015)
    The goal of this research is to investigate the feasibility and potential effectiveness of using vacuum-sealed, double-leaf partitions for applications in noise control. Substantial work has been done previously on double-leaf ...
  • Truitt, Andrew (University of Alabama Libraries, 2013)
    This study seeks to propose a novel approach to wind-based piezoelectric energy harvesting. A brief literature review of energy harvesting followed by a discussion of piezoelectric system dynamics is offered. Biomedical ...
  • McCarty, Rachael V. (University of Alabama Libraries, 2014)
    Atomic force microscopy (AFM) uses a scanning process performed by a microcantilever probe to create a three dimensional image of a nano-scale physical surface. The dynamics of the AFM microcantilever motion and tip-sample ...
  • Omidi, Ehsan (University of Alabama Libraries, 2015)
    Flexible structures are one of the most frequently used elements in different systems. They can be easily shaped to any desired form, they are light-weight, relatively inexpensive, and they have the required mechanical ...
  • Frey, Gary Owen (University of Alabama Libraries, 2015)
    The goal of this research is to model a piezoelectric flag as a membrane for the sake of energy harvesting. Typically, a flag is modeled as a beam, but it is modeled as a membrane in this study with the hopes of more ...
