  • Computationally efficient block diagonalization for downlink multiuser MIMO-OFDM systems

    Creator:
    El Amrani, Samia
    Abstract:
    One of the key challenges in downlink multiuser multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems is the mitigation of the multi-access interference when different users share the same subcarriers. In this work, the block diagonalization (BD) algorithm for inter-user interference pre-cancelation is extended to MIMO-OFDM systems. However, in...

  • 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...

  • A Wireless Energy Harvester for Powering Event-driven Internet-of-things Applications and Battery Charging

    Creator:
    Sadagopan, Kamala Raghavan
    Abstract:
    The need for sustainably powering unobtrusive internet-of-things applications has led to an interest in energy harvesting. Particularly, the proliferation of wireless communication and devices in the 2.4 GHz Industrial Scientific c Medical (ISM) band creates an opportunity to leverage commonly used devices for RF powering. This dissertation presents a low-quiescent-power...

  • Alternating-current thin-film electroluminescent device optical excitation experiments

    Creator:
    Cleary, Bradford A.
    Abstract:
    This thesis investigates two methods of optical excitation of alternating-current thin-film electroluminescent (ACTFEL) devices. The two experimental methods investigated in this thesis are the photo-induced charge (PIQ) and luminescence (PIL), and the subthreshold-voltage induced transferred charge (VIQ) techniques. PIQ/PIL experiments utilize an above-bandgap laser pulse to investigate the transport properties...

  • Analysis and optimal sizing of an energy storage system for wind farm applications

    Creator:
    Yen, Zuan Z.
    Abstract:
    Modern wind energy is the technology of choice with a short payback period for increasing renewable energy portfolios. Bonneville Power Administration (BPA), a United States power authority in the Pacific Northwest expects to increase their wind energy capacity from 2,000 megawatts to 6,000 megawatts within the next five years. Currently...

  • On the state and parameter estimation of stochastic bilinear systems : a sub-optimal filtering approach

    Creator:
    Shadman-Valavi, Ali
    Abstract:
    Bilinear systems due to their variable structure properties offer more versatility in modelling of nonlinear processes than linear systems. The state estimation problem for a continuous bilinear system with a continuous observation model is studied and the results are extended to the case where the observations are of a discrete...

  • A new comptutational method for constrained nonlinear programming

    Creator:
    Bhatia, Surendra P. S.
    Abstract:
    In this dissertation, a new computational method for equality constrained nonlinear programming is developed. Specifically, problems of minimizing a nonlinear objective function f(x) subject to constraints h(x) = 0, where f is a scalar valued, x is an n-vector and h is a m-vector with m < n is considered....

  • Validation of Wave Energy Converter Models and the Development of Control Strategies in WEC-Sim

    Creator:
    So, Ratanak
    Abstract:
    When the term renewable energy is mentioned in a conversation, wind, solar, and hydro energy typically come to mind. However, there is one major resource that has remained mostly untapped: wave energy. Wind and solar power technologies are well established around the world but they cannot generate electricity all the...

  • A methodology to reduce the strain on hydro turbines using advanced life extending control of multiple energy storage systems

    Creator:
    Brosig, Sean G.
    Abstract:
    Over the last 20 years, there has been rapid growth in the amount of installed wind power in the Pacific Northwest, specifically in the Columbia River Gorge. The variable and non-dispatchable nature of this resource requires that it be balanced in some form by other sources on the grid. In...
