  • Dynamic Methods to Improve Streaming of H.264 HD Video Over 802.11 Wireless Networks

    Creator:
    Sinky, Mohammed H.
    Abstract:
    Wireless High Definition Video Transmission (WHDVT) over 802.11-based networks enjoys widespread deployment among today's multimedia solutions. Examples include Intel® Wireless Display and Apple Airplay®, to name a few. In these systems, peer-to-peer networks are established over which H.264-encoded video is transported wirelessly to be decoded and played back at the...

  • A methodology to enable wind farm automatic generation control

    Creator:
    Han, Hai-Yue
    Abstract:
    Over the last decade the increase in penetration of wind power and its variable nature has begun to add considerable stress to and threatened the stability of the nation's grid. In order to continue growth wind farms will need to have the ability to participate in the same grid frequency...

  • Design techniques for low power ADCs

    Creator:
    Yu, Wenhuan
    Abstract:
    This dissertation presents an incremental analog-to-digital converter (ADC) with digital digital-to-analog converter (DAC) mismatch correction. A theoretical time-domain analysis technique was developed to predict the noise performance of the incremental ADC, and a new optimization technique was proposed to minimize the output noise. In the calibration mode, the incremental ADC...

  • Behavior-based mobility prediction for fast handoffs in wireless LANs

    Creator:
    Wanalertlak, Weetit
    Abstract:
    Wireless Networks have been widely adopted into a major part of today's network infrastructure. They have become a popular technology to not only expand the coverage of wired networks but also to interconnect a large wireless network, i.e., wireless mesh networks. As they allow more flexible communication than traditional wired-networks...

  • Efficient VLSI architectures for MIMO and cryptography systems

    Creator:
    Li, Qingwei
    Abstract:
    Multiple-input multiple-output (MIMO) communication systems have recently been considered as one of the most significant technology breakthroughs for modern wireless communications, due to the higher spectral efficiency and improved link reliability. The sphere decoding algorithm (SDA) has been widely used for maximum likelihood (ML) detection in MIMO systems. It is...

  • Digital phase-locked loops for multi-GHz clock generation

    Creator:
    Kratyuk, Volodymyr
    Abstract:
    A digital implementation of a PLL has several advantages compared to its analog counterpart. These include easy scalability with process shrink, elimination of the noise susceptible analog control for a voltage controlled oscillator (VCO) and the inherent noise immunity of digital circuits. Several recent digital PLL (DPLL) implementations have achieved...

  • Cryptanalysis and enhancement of authentication protocols

    Creator:
    Kim, Minho
    Abstract:
    Authentication protocols play important roles in network security. A variety of authentication protocols ranging from complex public-key cryptosystems to simple password-based authentication schemes have been proposed. However, currently there is no fully secure authentication scheme that can resist all known attacks. When a user authentication is performed over an insecure...

  • Crystal Records of the Origin, Evolution, and Thermal Histories of Magmas

    Creator:
    Bradshaw, Richard W., 1985-
    Abstract:
    In volcanic systems, magma is generally stored in the shallow crust prior to eruption. The conditions of this storage directly impact whether the magma eventually erupts, or crystallizes within the crust to form a pluton. In this dissertation I present four studies that investigate the storage conditions of a number...

  • Assessment of resistance and inheritance to Barley Yellow Dwarf Virus disease (BYDV) in five wheat cultivars (Triticum aestivum L.)

    Creator:
    Tola, Jaime
    Abstract:
    Barley Yellow Dwarf Virus (BYDV) is a major disease of wheat. Unfortunately, unlike barley where the Yd2 gene provides adequate levels of resistance, the situation in wheat is more complex. This study was designed to provide information regarding: 1) evaluation of methods of measuring resistance among selected cultivars; 2) identification...

  • The Role of Submesoscale Features in Transporting Heat and Salt Across Ocean Fronts

    Creator:
    Sanchez-Rios, Alejandra
    Abstract:
    The focus of this dissertation is the analysis of submesoscale and finescale features measured at oceanic fronts and the role they play in the transport of heat and salt. Two different geographical areas were used to analyze this transport: one, an area on the western side of the North Atlantic...
