  • 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...

  • Oscillators and phase locked loops for space radiation environments

    Creator:
    Vandepas, Martin
    Abstract:
    Circuits operating outside the earth’s atmosphere are more vulnerable to cosmic radiation and require special design consideration. The purpose of this work is to explore methods of mitigating the effect of radiation in phase locked loop (PLL) circuits. Several voltage controlled oscillators (VCOs) and two complete PLLs are designed and...

  • A methodology for efficient substrate noise estimation from large scale digital circuits in mixed signal SoC's

    Creator:
    Held, Martin A.
    Abstract:
    A methodology for rapid estimation of substrate noise generated by digital circuitry in mixed-signal circuits is presented. This methodology is incorporated into the Silencer! framework, and also provides for future improvements including pre-layout noise estimation. Measurements of a test chip fabricated in the TSMC o.25[mu]m heavily doped logic process validate...

  • Paths to Innovation: How Businesses Achieve Competitive Advantage

    Creator:
    Oster, Dylan
    Abstract:
    To detail common paths followed by companies to produce innovative products, I reviewed existing literature and conducted several semi-structured interviews with a variety of people from different companies and fields. Based on this research, I found that most (but not all) innovative products follow a few general paths. These paths...

  • Enhanced-accuracy oversampled data converters

    Creator:
    Ceballos, Jose Luis
    Abstract:
    Digital-to-analog converters (DACs) suffer from static and dynamic nonlinearity problems, which degrade their accuracy and performance. Mismatch errors in the analog components restrict the maximum achievable linearity. This thesis presents various techniques for correcting these errors. It describes a correction process for the nonlinear behavior of DACs, on three different...

  • Information theoretic approach to quantization and classification for signal processing, communications, and machine learning applications

    Creator:
    Thuan Nguyen D.
    Abstract:
    There are five main contributions of this dissertation. The first contribution is new closed-form expressions for channel capacity of a new class of channel matrices. The second contribution is the discovery of the structure for optimal binary quantizer and the associated methods for finding an optimal quantizer that maximizes mutual...

  • A Microgrid Design Case Study : Synchrophasor Placement and Development of a Protection Laboratory for the Oregon State University - Corvallis Campus

    Creator:
    Huo, Chen
    Abstract:
    In the past two years, Oregon State University (OSU) Corvallis campus suffered several power outages. The estimated cost of one of those outages was close to a million dollars worth of equipment and impact on research projects. Meanwhile, the campus grid operates with severely aging power assets. The reliability of...

  • Adaptive model reference control of highly maneuverable high performance aircraft

    Creator:
    Collins, David C. (David Charles), 1969-
    Abstract:
    This thesis presents an adaptive model reference controller for a highly maneuverable high performance aircraft, in particular, a modified F18. An adaptive controller is developed to maneuver an aircraft at a high angle of attack. Thus, the aircraft is required to fly over a highly nonlinear flight regime. The adaptive...

  • Network monitoring with focus on HTTP

    Creator:
    Schmid, Andreas
    Abstract:
    Since its introduction in the early 1990s, the quick growth of the World Wide Web (WWW) traffic raises the question of whether past Local Area Network (LAN) packet traces still reflect the current situation or whether they have become obsolete. For this thesis, several LAN packet traces were obtained by...

    Creator:
    Ramamurthy, Karthik
    Abstract:
    Standard methodologies exist for testing and characterizing digital circuits but the same cannot be said of analog circuits. Though much theoretical work has been done to model the linear and nonlinear aspects of analog circuits, a firm practical background for the design of testable analog cells has yet to be...
