    • Force plus graphics is not equal to vision plus haptics : towards usable haptic environments 

      Kirkpatrick, Arthur Edward (University of Oregon, 2000)
      Haptic environments are user interfaces incorporating a haptic display device, most commonly a point force device such as the PHANToM. Lederman and Klatzky's Exploratory Procedures work casts doubt on the usability of such ...
    • Support for model coupling: An interface-based approach 

      Bulatewicz, Tom (2006-06)
      There is an increasing need in the scientific community for the comprehensive simulation of complex, dynamic, physical systems. Often such simulations are built through model coupling, that is, the merging of existing, ...
    • A Novel Neural Network Analysis Method Applied to Biological Neural Networks 

      Dunn, Nathan A. (2006-08)
      This thesis makes two major contributions: it introduces a novel method for analysis of artificial neural networks and provides new models of the nematode Caenorhabditis elegans nervous system. The analysis method extracts ...
    • Gait animation and analysis for biomechanically-articulated skeletons 

      Wills, Eric David, 1977- (University of Oregon, 2008-03)
      Digital three-dimensional (3D) models are useful for biomechanical analysis because they can be interactively visualized and manipulated. Synthesizing and analyzing animal locomotion with these models, however, is difficult ...
    • Combating Phishing Through Zero-Knowledge Authentication 

      Knickerbocker, Paul, 1980- (University of Oregon, 2008-06)
      Phishing is a type of Internet fraud that uses deceptive websites to trick users into revealing sensitive information. Despite the availability of numerous tools designed to detect phishing, it remains a steadily growing ...
    • An "active vision" computational model of visual search for human-computer interaction 

      Halverson, Timothy E., 1971- (University of Oregon, 2008-12)
      Visual search is an important part of human-computer interaction (HCI). The visual search processes that people use have a substantial effect on the time expended and likelihood of finding the information they seek. This ...
    • Extending dynamic scripting 

      Ludwig, Jeremy R. (University of Oregon, 2008-12)
      The dynamic scripting reinforcement learning algorithm can be extended to improve the speed, effectiveness, and accessibility of learning in modern computer games without sacrificing computational efficiency. This dissertation ...
    • Algorithm capability and applications in artificial intelligence 

      Ray, Katrina (University of Oregon, 2008-12)
      Many algorithms are known to work well in practice on a variety of different problem instances. Reusing existing algorithms for problems besides the one that they were designed to solve is often quite valuable. This is ...
    • Knowledge support for parallel performance data mining 

      Huck, Kevin A., 1972- (University of Oregon, 2009-03)
      Parallel applications running on high-end computer systems manifest a complex combination of performance phenomena, such as communication patterns, work distributions, and computational inefficiencies. Current performance ...
    • Automated methods to infer ancient homology and synteny 

      Catchen, Julian M., 1978- (University of Oregon, 2009-06)
      Establishing homologous (evolutionary) relationships among a set of genes allows us to hypothesize about their histories: how are they related, how have they changed over time, and are those changes the source of novel ...
    • Measuring the Internet AS graph and its evolution 

      Boothe, Peter Mattison, 1978- (University of Oregon, 2009-09)
      As the Internet has evolved over time, the interconnection patterns of the members of this "network of networks" have changed. Can we characterize those changes? Have those changes been good or bad? What does "good" mean ...
    • Ontology databases 

      Le Pendu, Paea Jean-Francois, 1974- (University of Oregon, 2010-03)
      On the one hand, ontologies provide a means of formally specifying complex descriptions and relationships about information in a way that is expressive yet amenable to automated processing and reasoning. When data are ...
    • A software framework for simulation-based scientific investigations 

      Salman, Adnan M., 1965- (University of Oregon, 2010-03)
      This thesis provides a design and development of a software architecture and programming framework that enables domain-oriented scientific investigations to be more easily developed and productively applied. The key research ...
    • Image Processing as Applied to Medical Diagnostics 

      Thomas, Kristine A. (University of Oregon, 2010-06)
      Image processing is a powerful tool for increasing the reliability and reproducibility of disease diagnostics. In the hands of pathologists, image processing provides quantitative data from histological images which ...
    • Peer-to-peer streaming: Design and challenges 

      Magharei, Nazanin, 1979- (University of Oregon, 2010-12)
      Streaming multimedia content over the Internet is extremely popular mainly due to emerging applications such as IPTV, YouTube and e-learning. All these applications require simultaneous streaming of multimedia content from ...
    • Use of ontologies in information extraction 

      Wimalasuriya, Daya Chinthana (University of Oregon, 2011-03)
      Information extraction (IE) aims to recognize and retrieve certain types of information from natural language text. For instance, an information extraction system may extract key geopolitical indicators about countries ...
    • Virtual Environments for Human Centric Research 

      Masud, Md. Raihan (University of Oregon, 2011-06)
