  • Improving motion estimation with evolvable search algorithms

    Creator:
    Dill, Martin D.
    Abstract:
    Until now the topic of motion estimation, as used in video compression, has been dominated by search methodologies which are modifications of an exhaustive search. This research takes a completely new approach by applying two evolvable search algorithms, the Genetic Algorithm and the Genetic Program, to the area of motion...

  • Finite element modeling of dielectric waveguides

    Creator:
    Vishakhadatta, Gannavaram D.
    Abstract:
    Dielectric waveguides are becoming important for their numerous applications in integrated optics. The study of dielectric waveguides by analytical techniques is not sufficient for many variations in waveguide shape, anisotropy, and inhomogeneity commonly encountered in waveguide materials. This work studies the finite element method as an accurate tool for the...

  • Modelling of on-chip spiral inductors for silicon RFICs

    Creator:
    Melendy, Daniel
    Abstract:
    In high-frequency circuit design, performance is often limited by the quality of the passive components available for a particular process. Specifically, spiral inductors can be a major bottle-neck for Voltage-Controlled Oscillators (VCOs), Low-Noise Amplifiers (LNAs), mixers, etc. For designers to correctly optimize a circuit using a spiral inductor, several frequency-domain...

  • Implementation of display control node for a distributed microcontroller network

    Creator:
    Xu, Yan, 1954-
    Abstract:
    As hardware becomes cheaper and cheaper, there is an increasing interest in the implementation of distributed control networks with microcontrollers. Such networks are usually inexpensive and of high performance. In this thesis work, a low-cost display control unit for COLAN, a control-oriented network, is designed. The system is based on...

  • High-performance low-power microprocessor circuits

    Creator:
    Hsu, Steven K.
    Abstract:
    This thesis will discuss two critical components of a digital system -- domino logic styles and flip-flops. In today's microprocessors, both domino logic and flip-flops are essential to high-performance and low-power design. Two new domino logic styles are presented and analyzed, Double Edge Triggered (DET) and Double Data Rate (DDR)...

  • Predictive control using feedback- : a case study of an inverted pendulum

    Creator:
    Barrett, Spencer Brown
    Abstract:
    Vision is a flexible, non-contact sensor that can be used for position feedback in closed-loop control of dynamic systems. Current vision systems for industrial automation provide low sample rates and large sample delays relative to other types of position sensors. Poor sample rates and sample delays are a result of...

  • The architecture of VIS multimedia extension

    Creator:
    Kwon, Young-Kyong
    Abstract:
    In the past, multimedia technology focused mainly on designing high quality audio and graphical imagery as well as providing adequate performance levels that the users demand for multimedia applications. However, the concept of multimedia has expanded into New-Media that involves variety use of multimedia data in consumer-oriented applications, such as...

  • Analysis and modeling of lossy planar optical waveguides and application to silicon-based structures

    Creator:
    Remley, Catherine A.
    Abstract:
    This work is concerned with the modeling and analysis of lossy planar dielectric optical waveguides. Loss mechanisms which affect propagation characteristics are reviewed, and various representations of the propagation constant in the lossy case are defined. Waveguide structures which are susceptable to absorption and/or to leakage loss, in particular silicon-based...

    Creator:
    Zhang, Haowei
    Abstract:
    An extremely important area that has enabled or will enable many of the digital video services and applications such as VideoCD, DVD, DVC, HDTV, video conferencing, and DSS is digital video compression. The great success of digital video compression is mainly because of two factors. The state of the art...

  • Real-time data quality assessment using linear prediction

    Creator:
    Rentola, Christopher T. W.
    Abstract:
    The U.S. Air Force models many naturally occurring phenomena. To validate such models, an automated data collection system is used. Since validation is dependent upon correct data, an inexpensive method to detect erroneous data was investigated. The method uses a Wiener filter to predict values one sample in advance. If...
