  • Distributed OpenCL : a platform for distributed, heterogeneous computing for domain scientists

    Creator:
    Dillon, William H.
    Abstract:
    It is possible to purchase, for as little as $10,000, a cluster of computers with the capability to rival the supercomputers of only a few years ago. Now, users that have little to no experience developing distributed applications or managing a cluster are in a position to do so. To...

  • 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...

  • Sensorless Localization for Robots and Wheelchairs

    Creator:
    Subramanian, Ashwin
    Abstract:
    Despite an increase in the number of people who rely on manual wheelchairs, there are still substantial economic barriers to affordable and accessible localization systems. As a result, there is a pressing need to build a versatile yet low cost localization system for manual wheelchairs. Such systems allow users to...

  • 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...

  • 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...

  • UWB Low Power RF System for Localization

    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....

  • An efficient frequency controlled PFM for DC-DC converters

    Creator:
    Pai, Jeff
    Abstract:
    As more features are being integrated into mobile platforms, the demand for long battery life during standby mode has been increasing. Light load efficiency becomes one of essential features in today's DC-DC converter. The most effective method to improve light load efficiency is to operate the DC-DC converter under pulse-frequency-modulation...
