  • Energy efficient communication across on-chip wires in digital CMOS

    Creator:
    Postman, Jacob
    Abstract:
    For the past half century, CMOS process scaling has followed Moore's law, approximately doubling transistor density every 18 months. While locally routed wires have generally scaled with transistor size, longer wires have scaled at a slower rate and in some cases have grown larger as chip size and complexity have...

  • The Architecture of a Reusable Built-In Self-Test for Link Training, IO and Memory Defect Detection and Auto Repair on 14nm Intel SOC

    Creator:
    Querbach, Bruce
    Abstract:
    The complexity of designing and testing today's system on chip (SOC) is increasing due to greater integrated circuit (IC) density and higher IO and memory frequencies. SOCs for the mobile phone and tablet market have the unique challenge of short product development windows, at times less than six months, and...

  • Fundamental studies of atomic diffusion by computer simulation of atomic processes on the giga event scale and multiple PC's in parallel

    Creator:
    Zhang, Qiongshan
    Abstract:
    The classic treatment of diffusion by Einstein and by Chandrasekhar assumed conservative boundary conditions; mobile species were neither created nor destroyed on the sample surface. It is normal to assume that vacancies and host interstitials are created and annihilated on incoherent interfaces or free surfaces; i.e., these are assumed to...

  • Nonlinear control of high performance aircraft

    Creator:
    Bean, Ronnie A.
    Abstract:
    This thesis presents the design of various controllers for a highly maneuverable, high performance aircraft, namely the modified F-18. The aircraft was required to perform high angle-of-attack maneuvers, for which the aircraft behaves in as a highly nonlinear system. An adaptive PID controller was used to control the aircraft through...

  • Substrate noise coupling analysis in 0.18um silicon germanium (SiGe) and silicon on insulator (SOI) processes

    Creator:
    Pham, Hui En
    Abstract:
    Analysis of substrate noise coupling has been performed for a 0.18¹m lightly doped silicon germanium BiCMOS process. Techniques to minimize noise coupling in the chip and board design are presented, as well as methods for accurate modeling for substrate noise coupling simulations. Measurements from a test chip were taken to...

  • Accurate and efficient simulation of synchronous digital switching noise in system on a chip

    Creator:
    Habal, Husni
    Abstract:
    A new method is presented to compress switching information in large digital circuits. This is combined with an efficient approach of generating the noise signatures of cells in a digital library that results in an accurate and efficient approach for estimating the noise generated in digital circuits. This method provides...

  • Conditionally Gaussian processes in stochastic control theory

    Creator:
    Kolodziej, Wojciech Jan
    Abstract:
    An application of the theory of conditionally Gaussian random processes to filtering and stochastic control problems is presented here. The results due to Liptser and Shiryayev are proved to hold in the multidimensional case under somewhat relaxed conditions, when compared to the original ones. Such a generalization is required from...

  • Functional expansions in bilinear system analysis

    Creator:
    Karanam, Veerabhadra Rao
    Abstract:
    Bilinear systems, encountered in many important applications of engineering, biological and socio-economic systems, represent the logical step in complexity between the linear systems which are inadequate in the modeling of various dynamic processes and the difficult realm of nonlinear systems. This dissertation studies two functional expansions in bilinear system analysis-...

  • A remotely operated, autonomous wave energy converter system

    Creator:
    Lewis, Timothy M.
    Abstract:
    The potential for electric energy generation from ocean waves is substantial and much research is being conducted on the conversion process as a renewable, grid-connected, power source. Some of the same attributes that make wave energy harvesting attractive as a grid-connected source also make it attractive as a remote, or...

  • Compartmental analysis of the immune system

    Creator:
    Lawrence, Karen
    Abstract:
    A compartmental model of the immune system is simulated. Chapter I discusses the importance of such a model, reviews past immune system models, and summaries the immunological theory the model is based upon. In Chapter II, the compartmental representation of the immune system is developed from immunological and physiological theory....
