  • Multiple Instance Multiple Label Learning with Limited Supervision

    Creator:
    Nguyen, Tam
    Abstract:
    In weak supervision learning, label information can be provided at different levels of granularity. For example, in multi-instance multi-label learning, samples are organized into bags and labels for each class are provided at the bag level. For small datasets, this approach offers means of reducing the labeling efforts. However, in...

  • Part-based and Uncertainty-Aware Few-shot Object Segmentation in Images

    Creator:
    Nguyen, Khoi D.
    Abstract:
    This dissertation addresses few-shot object segmentation in images. The goal of segmentation is to label every image pixel with a class of the object occupying that pixel, where the class may represent a semantic object category or instance. In few-shot segmentation, training and test datasets have different classes. Every new...

  • Partial network coding with cooperation : a study over multi-hop communications in wireless networks

    Creator:
    Poocharoen, Panupat
    Abstract:
    The imperfections of the propagation channel due to channel fading and the self-generated noise from the RF front-end of the receiver cause errors in the received signal in electronic communication systems. When network coding is applied, more errors occur because of error propagation due to the inexact decoding process. In...

  • Convergence Analysis Framework for Fixed-Point Algorithms in Machine Learning and Signal Processing

    Creator:
    Vu, Trung
    Abstract:
    Iterative algorithms are simple yet efficient in solving large-scale optimization problems in practice. With a surge in the amount of data in past decades, these methods have become increasingly important in many application areas including matrix/tensor recovery, deep learning, data mining, and reinforcement learning. To optimize or improve iterative algorithms,...

  • Seismic wave attenuation of the crust and upper mantle in the Himalaya and South-Central Tibetan Plateau

    Creator:
    Monigle, Patrick W.
    Abstract:
    Recent geophysical and geological investigations of the Tibetan plateau have given rise to conflicting models of plateau growth and deformation, where the presence and extent of partial melt in the crust could be a determining factor. Here we investigate the attenuation structure of the crust and upper mantle, as attenuation...

  • Community Ecology and Population Genomics of Rhizopogon in the Madrean Sky Island Archipelago

    Creator:
    Piña Páez, Carolina G.
    Abstract:
    Anthropogenic induced climate change is predicted to alter distribution of existing plant populations. As plants migrate over space and time, populations often fragment and contract, affecting basic elements of population dynamics (e.g., population size, gene flow, genetic diversity, etc.). Little is known, however, how these impacts on plant species will...

  • Systemically Delivered Magnetic Hyperthermia for Cancer Treatment

    Creator:
    Albarqi, Hassan Ahmad M.
    Abstract:
    Despite advances in treatment, cancer remains among the leading causes of death in the world. Progress in the treatment of metastatic cancers was seen with chemotherapy and radiotherapy, however, the major drawbacks of conventional cancer therapies are limited efficacy and severe side effects. Magnetic fluid hyperthermia (MFH) is a new...

  • Graphite intercalation with fluoroanions by chemical and electrochemical methods

    Creator:
    Özmen Monkul, Bahar
    Abstract:
    New acceptor-type graphite intercalation compounds (GICs) containing perfluoroalkyl anions have been synthesized by using both chemical and electrochemical methods and characterized by elemental and thermogravimetric analyses. Investigation into these graphite intercalation compounds can provide novel materials and a detailed understanding of their properties. GICs of composition Cx[FB(C₂F₅)₃]·δF are prepared for...

  • Addressing the Risks of Nanoscale Polymers: Exposure, Behavior, and Toxicity

    Creator:
    Stine, Jared
    Abstract:
    Nanoscale polymers (including nanoplastics) are widely present through commerce and make their way into the environment. As the improper disposal of plastic waste leads to continued accumulation and degradation of plastic pollution, the presence of plastic particles less than 1 micron (μm) in size (nanoplastics) will increase. Heightened concern over...

  • Development and characterization of novel hydrogels for nucleus pulposus replacement

    Creator:
    Bader, Rebecca A.
    Abstract:
    Hydrogels have been proposed as candidates for nucleus pulposus replacement due to their similarity in mechanical behavior to the native tissue when subjected to transient or static loading; however, given the viscoelastic nature of soft biological tissues, the lack of dynamic testing is a significant inadequacy in the studies performed...
