  • Automated Classification of Complex Oculomotor Behavior 

    Komogortsev, Oleg V. (2012-06-10)
    Complex oculomotor behavior in response to a simple step stimulus can include a variety of different types of saccadic patterns including combinations of normal saccades, simple/corrected/multi-corrected overshoots/undershoots, ...
  • Fast Target Selection via Saccade-driven Methods 

    Komogortsev, Oleg V.; Ryu, Young Sam; Koh, Do Hyong (2012-06-10)
    Three fast, saccade driven, target selection methods are explored. The first method selects a target at the beginning of a saccade with the objective of providing target selection in almost constant amount of time regardless ...
  • Coverings of Finite Sets by Random Covers, with Applications to the HELP Protocol 

    Ogden, Robert D. (2011-01-08)
    If we choose subsets of a finite set s at random, according to some specified distribution, how many subsets have to be chosen until s is covered? We solve this problem for distributions invariant under permutations of s ...
  • Requirements Management in an Agile-Scrum 

    Oyeyipo, Elizabeth O.; Mueller, Carl J. (2011-01-03)
    Producing high quality software products meeting the stakeholder's requirements is a major challenge in software engineering. Dynamically changing environments make changes to requirements in the software development process ...
  • The Intractability of Finite State Machine Test Sequences 

    Ihemelandu, Ngozi I.; Mueller, Carl J. (2011-01-01)
    Much of the high reliability and safety critical software applications use various forms of Finite State Machines (FSM) to describe their behavior. Testing software with state behavior presents a number of challenges to ...
  • Statistical Approach to Person Identification via Unique Properties of the Oculomotor Plant 

    Mechehoul, Mahmoud; Jayarathna, Sampath; Komogortsev, Oleg V. (2010-06-01)
    This paper presents a statistical approach that employs Hotelling's T-square test for the purpose of novel biometric identification based on unique static and dynamic properties of the oculomotor plant (OP) represented by ...
  • Clustering in the Cloud: Clustring Algorithms to Hadoop Map/Reduce Framework 

    Wang, Xuan (2010-05-04)
    Cloud computing has gained an increasing popularity over the years for its great potentials. It is a logical and forward-thinking solution for addressing key business demands. Cloud computing truly represents what enterprise ...
  • Classification Algorithm for Saccadic Oculomotor Behavior 

    Komogortsev, Oleg V.; Gobert, Denise; Dai, Zanxun (2010-05-04)
    This paper presents a detection algorithm that allows automatic classification of hypermetric and hypometric oculomotor plant behavior in cases when saccadic behavior of the oculomotor plant is assessed during the course ...
  • An Effort-based Framework for Evaluating Software Usability Design 

    Tamir, Dan; Mueller, Carl J.; Komogortsev, Oleg V. (2010-03-12)
    One of the major stakeholder complaints is the usability of software applications. Although there is a rich amount of material on good usability design and evaluation practice, software engineers may need an integrated ...
  • Biometric Identification via an Oculomotor Plant Mathematical Model 

    Komogortsev, Oleg V.; Jayarathna, Sampath; Aragon, Cecilia R.; Mahmoud, Mechehoul (2009-11-19)
    There has been increased interest in reliable, non-intrusive methods of biometric identification due to the growing emphasis on security and increasing prevalence of identity theft. This paper presents a new biometric ...
  • Qualitative and Quantitative Scoring and Evaluation of the Eye Movement Classification Algorithms 

    Komogortsev, Oleg V.; Jayarathna, Sampath; Koh, Do Hyong; Gowda, Sandeep Munikrishne (2009-09-16)
    This paper presents a set of qualitative and quantitative scores designed to assess performance of the various eye movement classification algorithms. The scores are designed to provide a foundation for the eye tracking ...
  • Facet-based Tetrahedralization Software 

    Hazlewood, Carol (1995-04-12)
