  • Models and Modeling in Capstone Physical and Virtual Laboratory Projects

    Creator:
    Nefcy, Erick J.
    Abstract:
    The research presented in this dissertation focuses on the model generation and modeling processes of student teams that participate in capstone, undergraduate engineering physical and virtual laboratory projects. The Heat Exchange Laboratory Project, the Ion Exchange Laboratory Project, and the Virtual Chemical Vapor Deposition (CVD) Laboratory Project provide the context...

  • A study of ZnS:Mn electroluminescent phosphors grown by halide transport chemical vapor deposition

    Creator:
    Chen, Chia-Jen
    Abstract:
    A low pressure halide transport chemical vapor deposition (HTCVD) system to grow ZnS:Mn electroluminescent phosphors is characterized. Reactor parameters such as gas composition, gas flow rate, and source and substrate temperature are investigated. Crystal structure is investigated using x-ray diffraction, electron spin resonance, and transmission electron microscopy. Chemical characterization includes...

  • Evaluation of cathodic protection in reinforced concrete bridges

    Creator:
    Abooameri, Farid
    Abstract:
    Steel corrosion in reinforced concrete is a major concern to transportation agencies nationwide because of the expenses incurred for repair and ultimate shortening of bridge life. Cathodic protection (CP), as a remedy, has been applied to reinforced bridges in the US since 1974. However, application of this technique is largely...

  • Electrochemical modeling of cathodic protection systems applied to reinforced concrete structures

    Creator:
    Muehlenkamp, Erik B.
    Abstract:
    A numerical model for the cathodic protection of steel in reinforced concrete is developed. Parameters are set to represent a three-dimensional section of a bridge beam exposed to the atmosphere and coated with a thermally sprayed zinc anode. Both diffusion of oxygen and conduction of charge within the concrete are...

  • Technology to promote concept-based, active learning and enable education research

    Creator:
    Brooks, Bill J.
    Abstract:
    This dissertation centers on development of two web-based, in class learning tools, the AIChE Concept Warehouse (CW) and the Web-based Interactive Science and Engineering Learning Tool (WISE), and describes the investigation of student learning through their use. The intent of these tools is to promote deeper conceptual understanding in students...
