  • Mechanical design under changing customer requirements case study : BugID

    Creator:
    Fagan, Chris R.
    Abstract:
    Customer requirements and engineering specifications will influence the direction of the design in any product, so it is crucial to make the requirements as stable as possible so quality designs can be produced on time within a budget. It would be optimal for requirements and specifications to remain constant but...

  • Low-power dynamic CMOS circuits in high-performance memory arrays

    Creator:
    Patwary, Md. Ataur R.
    Abstract:
    Dynamic CMOS circuits are commonly used in high-performance memory arrays to implement wide-NOR logic functions for their read and search operations. This is because dynamic circuits have significantly higher speed and lower area compared to static circuits for performing similar operations. Register File (RF) arrays are located at the top...

  • The dynamic shear moduli of blubber for selected large whale species

    Creator:
    Summers, Michael P.
    Abstract:
    Whale blubber is the insular tissue layer located between the dermis and the superficial fascia layer which sheathes the whale's musculature. It is made up of a lipid matrix ramified with strong, structural collagen and elastic fiber bundles, but little is known of its mechanical properties. Knowing these properties adds...

  • A photoactivable microfluidic device for heavy metal ion extraction

    Creator:
    Nammoonnoy, Jintana
    Abstract:
    The development of microfluidic devices for heavy metal extraction is presented in this dissertation. Various research areas, covering subjects from photochromic compound syntheses to microchip fabrication techniques are explored to develop microfluidic devices capable of extracting heavy metal ions from drinking water. Through integration of the beneficial characteristics of both...

  • Processing effects on the ductility of chromium-vanadium alloys

    Creator:
    Murdock, Hailey M.
    Abstract:
    The next generation of high temperature structural alloys must exhibit exceptional resistance to fracture, creep, oxidation, and fatigue at high temperatures. Chromium is being considered due to its high melting point (>1800°C), relatively low density (~7.2 g/cc), high temperature strength, and oxidation resistance. Limiting the use of chromium is its...

  • Effect of ambient environment on the fracture and fatigue properties of Zr-based bulk metallic glasses

    Creator:
    Philo, Sarah L.
    Abstract:
    The effect of ambient environment on the fatigue behavior of two Zr-Ti-Cu-Ni-Be bulk metallic glasses (BMGs) is examined in the present study. The first metallic glass, Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅, was tested to establish the presence of an environmental effect in the fatigue growth curve measured in ambient air. Fatigue growth curves produced...

  • Developing Design Model for Cellulose Nanocomposites

    Creator:
    Shir Mohammadi, Meisam
    Abstract:
    Today nano scale materials are being used for wide range of applications. One promising topic in nano scale materials is using them for reinforcement of different polymeric materials to reach desirable stiffness properties. The stiffness of these materials is mostly found experimentally because the nanocomposite community lacks a decent analytical...

  • Analysis and modeling of monolithic on-chip transformers on silicon substrates

    Creator:
    Mayevskiy, Yevgeniy
    Abstract:
    Passive components, including spiral inductors and transformers, fabricated on silicon-based substrates are placing an increasing demand on radio-frequency integrated circuit (RFIC) design. Performance of the RFIC suffers from several non-ideal effects that must be taken into account in order to create a successful design. In particular, monolithic transformers can be...

  • Dissipation and wavepacket collision in carbon nanotube waveguides

    Creator:
    Saranam, Venkata Rajesh
    Abstract:
    Carbon nanotubes (CNTs) superior mechanical, electrical and thermal properties make them attractive components in nanomechanical devices. Their large aspect ratio and low density makes them ideal candidates for high frequency resonators in numerous applications including wireless communication, and mass and chemical sensors. One reason why CNTs have been slow to...

  • Rapid bidirectional power flow of supercapacitor bank energy storage through grid-tied inverters for improved renewables integration

    Creator:
    Bostrom, Arne
    Abstract:
    The variable output of renewables such as wind and solar causes fluctuations of power flow that can adversely affect power system operation, especially at high levels of penetration. The coordination of multiple energy storage solutions can mitigate integration challenges by providing a buffer from variable renewables. This thesis presents the...
