  • Use of BC-523a liquid scintillator for simultaneous neutron spectroscopy and gamma counting with the implementation of a neutron history reconstruction algorithm

    Creator:
    Frey, Wesley D.
    Abstract:
    Real-time, high efficiency neutron spectroscopy has, historically, been a persistent challenge in the field of radiation detection and, for the most part, has gone unsolved. The most promising method to resolve this challenge, is the boron-capture technique using an organic scintillation system (BC-523a). Detectors that utilize this method possess an...

  • Essays on the effect of product recalls and mergers on firm performance

    Creator:
    Yan, Wenfeng
    Abstract:
    This dissertation investigates the effect of endogenous and exogenous events on firm behavior and performance. These are fundamental questions in economics. The contribution of this study is threefold. First, it provides estimates of the impact of mergers on railroad efficiency, which has important antitrust implications. Second, it provides new estimates...

  • A perceived-risk curriculum for at-risk learners

    Creator:
    Kash, Laurel Renee
    Abstract:
    Although perceived-risk curriculum, that is, where the learner experiences effects of eustress (positive stress), has been used in Arts or outdoor activities, it has not been used in school classrooms. Milkman’s 1996 studies of after-school Project Self Discovery demonstrated that at-risk students lessened their adverse risky behaviors, such as substance...

  • Structure-Property Relationships of Disordered Electronic Materials : From Crystalline to Amorphous

    Creator:
    Surta, Todd Wesley, Jr.
    Abstract:
    Two perovskite materials (Bi0.5(A)0.5)(Sc0.5Nb0.5)O3, where A = K+ and Na+ were synthesized phase pure for the first time. Their structures were determined by indexing synchrotron X-ray diffraction data and subsequent combined Rietveld refinement on neutron and synchrotron X-ray diffraction data revealing significant disorder on the A-sites of these materials. A...

  • Algorithms for massive biological datasets

    Creator:
    Bryant, Douglas W. (Douglas Wesley)
    Abstract:
    Within the past several years the technology of high-throughput sequencing has transformed the study of biology by offering unprecedented access to life's fundamental building block, DNA. With this transformation's potential a host of brand-new challenges have emerged, many of which lend themselves to being solved through computational methods. From de...

  • The behavior of economic agents and market performance

    Creator:
    Gokhale, Jayendra
    Abstract:
    This dissertation addresses issues concerning the behavior of firms, which has significant effects on performance. In the first study, we empirically investigate the effect of the reduction in number of firms on price competition in the U.S. macro-brewing industry. The number of macro brewing firms decreased from 766 in 1935...

  • The language of mathematics : a functional definition and the development of an instrument of measure teacher perceived self-efficacy

    Creator:
    Gray, Virginia
    Abstract:
    Mathematics is permeated with language; it appears in the form of new words and some old words with new meanings. There are new symbols to be able to read and consume; much information is presented in tabular or graphic form, and finally the language in a mathematics class has its...

  • Understanding and improving error-correcting output coding

    Creator:
    Kong, Eun Bae
    Abstract:
    Error-correcting output coding (ECOC) is a method for converting a k-classsupervised learning problem into a large number L of two-class supervised learningproblems and then combining the results of these L evaluations. Previous researchhas shown that ECOC can dramatically improve the classi cation accuracy of supervisedlearning algorithms that learn to classify...

  • Machine Learning Methods for Computational Sustainability

    Creator:
    Liu, Liping
    Abstract:
    Maintaining the sustainability of the earth’s ecosystems has attracted much attention as these ecosystems are facing more and more pressure from human activities. Machine learning can play an important role in promoting sustainability as a large amount of data is being collected from ecosystems. There are at least three important...
