  • Energy-efficient routing for delay-constrained data traffic in linear wireless sensor networks

    Creator:
    Alesaimi, Hani
    Abstract:
    Linear wireless sensor networks (LWSN) are special class of wireless sensor networks where sensor nodes are deployed in a straight line. Monitoring industrial pipelines, railroads, tunnels, power lines, and borders are applications of LWSNs. Wireless sensors are tiny devices with limited energy resources; therefore, efficient energy routing in LWSNs is...

  • Development of two-variable maximum power point tracking control for ocean wave energy converters utilizing a power analysis and data acquisition system

    Creator:
    Amon, Ean A.
    Abstract:
    Ocean wave energy shows great potential as a developing form of renewable energy. However, challenges arise in maturing this technology to achieve cost-effective energy conversion. Development and testing of wave energy converters can be problematic due to the harsh environment in which they are operated. To promote development of this...

  • Low-Power 12-bit Quasi-Passive Segmented DAC Implemented in 130nm CMOS Technology

    Creator:
    Pierce, Alexander G.
    Abstract:
    This thesis work proposes a low-power 12-bit digital-to-analog converter (DAC) designed in a 130nm process. The DAC to be presented is of a segmented design where the architecture is split into pipelined and thermometer coded segments. This allows for high linearity and low distortion while maintaining high speed and low...

  • Channel estimation and data detection for mobile MIMO OFDM systems

    Creator:
    Gao, Jie
    Abstract:
    Designing spectral efficient, high-speed wireless links that offer high quality- of-service and range capability has been a critical research and engineering challenge. In this thesis, we mainly address the complexity and performance issues of channel estimation and data detection in multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems over...

  • Timing jitter and phase noise in electronic oscillators

    Creator:
    Zhang, Chengwei
    Abstract:
    In the first part of this dissertation, low frequency l/f or flicker noise in the frequency range of Hz to kHz has been identified and demonstrated to be described by temperature fluctuations in heat conduction in bipolar transistors operated at higher power densities. This noise phenomenon is not described by...

  • Structured representation of composite software changes

    Creator:
    Chabra, Aarti
    Abstract:
    In a software development cycle, programs go through many iterations. Identifying and understanding program changes is a tedious but necessary task for programmers, especially when software is developed in a collaborative environment. Existing tools used by the programmers either lack in finding the structural differences, or report the differences as...

  • Performance timing for keyframe animation

    Creator:
    Terra, Sílvio César Lizana
    Abstract:
    This thesis presents a novel technique for retiming keyframe-based animation. We call our approach Performance Timing. Keyframing is a standard technique for generating computer animation that typically requires artistic ability and a set of skills for the software package being used. From our experience observing novice animators and their work,...

  • DC/AC Stability of In-Ga-Zn-O Thin-Film Transistors

    Creator:
    Zhou, Fan
    Abstract:
    The electrical stability of amorphous indium-gallium-zinc oxide (a-IGZO) thinfilmtransistors (TFTs) is investigated for flat-panel display applications. Althoughproducts incorporating a-IGZO TFT backplanes are already commercially available,e.g., iMac with 5K retina display, technical challenges need to be addressed for nextgenerationapplications, e.g., active-matrix organic light-emitting diode displays.Device stability is one crucial issue. The...

  • Low-power high-linearity digital-to-analog converters

    Creator:
    Kuo, Ming-Hung
    Abstract:
    In this thesis work, a design of 14-bit, 20MS/s segmented digital-to-analog converter (DAC) is presented. The segmented DAC uses switched-capacitor configuration to implement 8 (LSB) + 6 (MSB) segmented architecture to achieve high performance for minimum area. The implemented LSB DAC is based on quasi-passive pipelined DAC that has been...

  • Investigation and comparison of generators for dynamic operation in ocean buoys

    Creator:
    Schacher, Anthony Clinton
    Abstract:
    A significantly untapped renewable energy source exists in the world's oceans. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world. Ocean energy extraction is an old concept, and it is currently seeing the benefit of advancing...
