  • Stochastic properties of morphological filters

    Creator:
    Zhu, Feihong
    Abstract:
    Most of the existing research on mathematical morphology is restricted to the deterministic case. This thesis addresses the void in the results on the stochastic properties of morphological filters. The primary results include analysis of the stochastic properties of morphological operations, such as dilation, erosion, closing and opening. Two unbiased...

  • Consumer perceptions of apparel products in Internet shopping

    Creator:
    Kim, Mi-Jung
    Abstract:
    The purpose of the present study was to determine consumer perceptions of apparel products in Internet shopping. According to the existing literature, four categories of perceptions play primary roles for apparel shopping consumer decisions: apparel appearance, apparel comfort, fabric characteristics, and apparel fit. The present study aimed to observe how...

  • Two-grid a-priori and a-posteriori error analysis for coupled elliptic and parabolic systems with applications to flow and transport problems

    Creator:
    Klein, Viviane
    Abstract:
    We develop several a-priori and a-posteriori error estimates for two-grid finite element discretization of coupled elliptic and parabolic systems with a set of parameters P. We present numerical results that verify the convergence order of the numerical schemes predicted by the a-priori estimates. We present numerical results that verify the...

  • Renewal risk processes with stochastic returns on investments : a unified approach and analysis of the ruin probabilities

    Creator:
    Constantinescu, Corina D.
    Abstract:
    This thesis considers one of the classical problems in the actuarial mathematics literature, the decay of the probability of ruin in the collective risk model. The claim number process N(t) is assumed to be a renewal process, the resulting model being referred as the Sparre Andersen risk model. The inter-claim...

  • A performance study of multithreading

    Creator:
    Kwak, Hantak
    Abstract:
    As the performance gap between processor and memory grows, memory latency will be a major bottleneck in achieving high processor utilization. Multithreading has emerged as one of the most promising and exciting techniques used to tolerate memory latency by exploiting thread-level parallelism. The question however remains as to how effective...

  • Hybrid Multiscale Methods with Applications to Semiconductors, Porous Media, and Materials Science

    Creator:
    Costa, Timothy B.
    Abstract:
    In this work we consider two multiscale applications with tremendous computational complexity at the lower scale. First, we examine a model for charge transport in semicon- ductor structures with heterojunction interfaces. Due to the complex physical phenomena at the interface, the model at the design scale is unable to adequately...

  • Computing entropy for Z²-actions

    Creator:
    Pierce, Larry A.
    Abstract:
    For a certain class of Z²-actions, we provide a proof of a conjecture that the ratio of the Perron eigenvalues of the transfer matrices of the free boundary restrictions converge to the entropy of that action. Also, a novel method for computing the entropy of Z²-actions is conjectured.

  • Middle school teachers’ use of a formative feedback guide in mathematics problem solving instruction

    Creator:
    Strowbridge, Jessica
    Abstract:
    The purpose of this study was to address the implementation fidelity of one part of a professional development model developed by the Northwest Regional Educational Laboratory (NWREL). Specifically, this research investigates middle school teachers’ use of a formative feedback guide developed by NWREL staff, examining the reliability with which teachers...
