  • Hybrid visualization of asymmetric tensor fields : glyphs and hyperstreamlines

    Creator:
    Palke, Darrel
    Abstract:
    Asymmetric tensor fields are useful for understanding fluid flow and solid deformation. They present new challenges, however, for traditional tensor field visualization techniques such as hyperstreamline placement and glyph packing. This is because the physical behavior of tensors inside real domains where eigenvalues are real is fundamentally different from the...

  • The Variable Speed Wave Equation and Perfectly Matched Layers

    Creator:
    Kim, Dojin
    Abstract:
    A perfectly matched layer (PML) is widely used to model many different types of wave propagation in different media. It has been found that a PML is often very effective and also easy to set, but still many questions remain. We introduce a new formulation from regularizing the classical Un-Split...

  • Examining equity in out-of-pocket expenditures and utilization of healthcare services in Malawi

    Creator:
    Mwandira, Ruth
    Abstract:
    Best international health practice requires that all people benefit equally from health care services regardless of their socio-economic status and that healthcare payments be based on ability to pay. Although recent household surveys in Malawi show progress in a number of health indicators population averages, many inequalities in health outcomes...

  • Disparities in Health Outcomes and Health Care Access : A Quantitative Intersectional Approach

    Creator:
    Alvarado, Carla S.
    Abstract:
    Health disparity scholars and researchers call to expand the conceptualization of health disparities research beyond the predominant and long-standing race-based analyses. The call requests the inclusion of frameworks and theories that reflect the complex, multi-level and multifactorial social processes that yield health disparities. Intersectionality is a theoretical framework that is...

  • Interactive player tracking for videos in American football

    Creator:
    Bawaskar, Amit
    Abstract:
    This thesis presents an interactive software tool for tracking a moving object in a video. In particular, we focus on the problem of tracking a player in American football videos. Object tracking is one of the fundamental problems in computer vision. It is one of the most important components in...

  • On feature relevance feedback methods : incorporating labeled user features

    Creator:
    Oberst, Ian
    Abstract:
    In text classification, labeling features is often less time consuming than labeling entire documents. In situations where very little labeled training data is available, feature relevance feedback has the potential to dramatically increase classification performance. We review previous work on incorporating feature relevance feedback in the form of labeled features...

  • Supporting the learning process of open source novices : an evaluation of code and project history visualization tools

    Creator:
    Park, Yunrim
    Abstract:
    Active participation and collaboration of community members are crucial to the continuation and expansion of open source software projects. Researchers have recognized the value of community in open source development and studied various aspects of it including structure of communities, motivations for participation, and collaboration among members. However, the majority...

  • Novel approaches to promoting end-user programming

    Creator:
    Bahmani, Faezeh
    Abstract:
    End-user programming has become widespread. The increasing size of this population and the prevalence of barriers that they face has sparked the development of approaches that promote end-user programing by helping them overcome barriers and teaching them programming. Despite the fact that these approaches have done well in achieving those...

  • Assessing equity in health system finance and health care utilization : the case of Chile, and a model to measure health care access

    Creator:
    Núñez Mondaca, Alicia Lorena
    Abstract:
    Chile has experienced great success in terms of economic growth in the last decades. This growing economy brings changes in the Chilean health care system. Its health care system was primarily funded by state sources until 1981, when a major reform was introduced that established new rules for the health...

    Wade, Emily C.
    Abstract:
    Industrial reprocessing of irradiated nuclear fuel (INF) is one of the most complex procedures performed on a large scale; the process is intricate due to the mix of radionuclides present in INF. As a global trend for nuclear power and reprocessing continues, research is geared toward optimizing the extraction of...
