  • An enhanced swing differential Colpitts CMOS VCO for low-voltage operation

    Creator:
    Farahbakhshian, Farhad
    Abstract:
    An enhanced swing differential Colpitts VCO (ESDC-VCO) dramatically improves the swing of a Colpitts VCO by allowing the signal to swing below ground and above the supply voltage. Fabricated in a 1P8M 0.13 um CMOS process, the ESDC-VCO operates at 4.9GHz with a 0.475-V supply and consumes 2.7mW. The measured...

  • Computational Fluid Dynamics Modeling of the Density Evolution Inside of the Helium-3 Enhanced Negative Reactivity Insertion (HENRI) System

    Creator:
    Balderrama Prieto, Silvino Alejandro
    Abstract:
    The testing of nuclear fuel under reactivity-initiated accident (RIA) conditions is paramount for the better understanding of the fuel’s behavior during this transient accident events. The Transient Reactor Test (TREAT) facility is a nuclear reactor that will be capable of recreating the thermal-hydraulic and neutronic boundary conditions representative of RIA...

  • Dynamic and Dual Streaming Methods for H.264 Video and Parallel Performance Modeling

    Creator:
    Johnson, Taylor N.
    Abstract:
    Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless...

  • Electronic Properties of Passive Films on Carbon Steel Rebar in Simulated Concrete Pore Solutions

    Creator:
    Williamson, Jon W.
    Abstract:
    In the highly alkaline environment of concrete, carbon steel rebar is protected against corrosion by a passive oxide/oxyhydroxide film. Understanding the characteristics of this passive film, and how it depassivates, is the key for mitigating problems associated with steel corrosion in concrete. Although a large number of electrochemical and analytical...

  • Discrete trap modeling of thin-film transistors

    Creator:
    Yerubandi, Ganesh Chakravarthy
    Abstract:
    A discrete trap model is developed and employed for elucidation of thin-film transistor (TFT) device physics trends. An attractive feature of this model is that only two model parameters are required, the trap energy depth, E[subscript T], and the trap density, N[subscript T]. The most relevant trends occur when E[subscript...

  • Secrecy of massive MIMO systems under antenna failure

    Creator:
    Assiri, Mohammad
    Abstract:
    As the fifth generation of mobile communication systems (5G) is being deployed, massive multiple-input multiple-output (MIMO) serves as one of its enabling technologies where reliable and ultra low latency communications are achieved while being power and spectrum efficient. This thesis studies the security aspect of massive MIMO system from the...

  • Routerless Network-on-chip

    Creator:
    Alazemi, Fawaz
    Abstract:
    Traditional bus-based interconnects are simple and easy to implement, but the scalability is greatly limited. While router-based networks-on-chip (NoCs) offer superior scalability, they also incur significant power and area overhead due to complex router structures. In this thesis, a new class of on-chip networks, referred to as Routerless (RL) NoCs,...

  • Exploring IMU Attitude and Position Estimation for Improved Location in Indoor Environments

    Creator:
    Zhang, Shengkai
    Abstract:
    Wearable sensors with an inertial measurement unit (IMU) are popular for indoor positioning and activity pattern detection. The IMUs can be connected to a wireless transmission module, allowing users to monitor and process motion-related parameters remotely. Because of the complexity and uncertainty of signals in indoor environments, a radio frequency...

  • A study of micro-scale, fractal-like branching flow networks for reduced pumping power and improved temperature uniformity

    Creator:
    Alharbi, Ali Y.
    Abstract:
    A first generation, one-dimensional predictive model is proposed for designing heat sinks with fractal flow networks. A three-dimensional computational fluid dynamics (CFD) model is analyzed as a means for validating the model and identifying areas for improvement. Two separate CFD models were developed. One was analyzed with conjugate heat transfer...

    Creator:
    Sheokand, Anoop
    Abstract:
    Real time indoor positioning awareness systems aim to add localization capabilities to upcoming wireless technologies that are quickly becoming an important feature for indoor environment. RF-based impulse-radio ultra-wideband (IR-UWB) is a promising technology for in-door positioning systems due to obstacle penetration capabilities, immunity to multi-path and fading, and high resolution....
