  • Uniform residence time in microreactor-assisted solution deposition of CdS thin-films for CIGS photovoltaic cells

    Creator:
    Hires, Clayton Lamar
    Abstract:
    Photovoltaic (PV) cells have long been an attractive alternative for the consumption of fossil fuels but current manufacturing practices suffer from poor energy efficiency, large carbon footprints, low material utilization, high processing temperatures and high solvent usage. A critical step in PV production is the deposition of CdS as a...

  • Highly digital power efficient techniques for serial links

    Creator:
    Inti, Rajesh
    Abstract:
    Low power, high speed serial transceivers are employed in a wide range of applications ranging from chip-to-chip, backplane, and optical interconnects. Apart from being capable of handling a wide range of data rates, the transceivers should have low power consumption (mW/Gbps) and be fully integrated. This work discusses enabling techniques...

  • 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...

  • An artificial neural network approach to laser-based direct part marking of data matrix symbols

    Creator:
    Jangsombatsiri, Witaya
    Abstract:
    Certain applications have recently appeared in industry where a traditional bar code printed on a label will not survive because the item to be tracked has to be exposed to harsh environments. Laser direct-part marking is a manufacturing process used to create permanent marks on a substrate that could help...

  • 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...

  • 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...

  • Comparison of time-domain and frequency-domain phase noise analyses

    Creator:
    Vytyaz, Igor
    Abstract:
    This thesis presents a comparison of time-domain and frequency-domain algorithms for phase noise calculation in oscillators. Floquet theory provides the mathematical foundation for these calculations and the numerical methods employ perturbation projection vectors (PPVs). The PPVs are an estimate of an oscillator's sensitivity to noise. The in-house circuit simulator SPICE3...

  • 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...

  • 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...
