    • Discount Learnability Evaluation 

      Santos, Paulo J.; Badre, Albert (Georgia Institute of Technology, 1995)
      Learnability evaluation has traditionally required expensive and time-consuming techniques. Practitioners have refrained from performing extended learnability evaluation due to its prohibitive costs. We propose a discount ...
    • Discovery Visualization and Visual Data Mining 

      Ribarsky, William; Katz, Jochen; Jiang, Frank; Holland, Aubrey (Georgia Institute of Technology, 1999)
      This paper describes discovery visualization, a new visual data mining approach that has as a key element the heightened awareness of the user by the machine. Discovery visualization promotes the concept of continuous ...
    • Distributed Mediation of Imperfectly Sensed Context in Aware Environments 

      Dey, Anind K.; Mankoff, Jennifer C.; Abowd, Gregory D. (Georgia Institute of Technology, 2000)
      Current context-aware services make the assumption that the context they are dealing with is correct. However, in reality, both sensed and interpreted context is often imperfect. In this paper, we describe an architecture ...
    • Distributed Multi-AUV Coordination in Naval Mine Countermeasure Missions 

      Sariel, Sanem; Balch, Tucker; Stack, Jason (Georgia Institute of Technology, 2006)
      In this paper, we evaluate performance of our coordination framework, for Naval Mine Countermeasure (MCM) missions on the ALWSE-MC simulator. Our coordination framework integrates a distributed task allocation scheme, ...
    • Do Algorithm Animations Aid Learning? 

      Byrne, Michael Dwyer; Catrambone, Richard; Stasko, John T. (Georgia Institute of Technology, 1996)
      Two experiments examined the general claim that animations can help students learn algorithms more effectively. Animations and instructions that explicitly required learners to predict the behavior of an algorithm were ...
    • Does Multimedia Information Help People Learn? 

      Najjar, Lawrence Joseph (Georgia Institute of Technology, 1995)
      Multimedia is being used increasingly to provide computer-based instruction. While people generally believe that multimedia information helps people learn better than "monomedia" information, empirical support for this ...
    • Domisilica: Providing Ubiquitous Access to the Home 

      Mankoff, Jennifer C.; Abowd, Gregory D. (Georgia Institute of Technology, 1997)
      The Domisilica project is exploring future computing environments centered around the home. We envision a future in which objects in the home, such as appliances and rooms, are enhanced with computational capabilities that ...
    • Dual Coding as a Possible Explanation for the Effects of Multimedia on Learning 

      Najjar, Lawrence Joseph (Georgia Institute of Technology, 1995)
      This paper examines the possibility of using Paivio's (1971, 1991; Clark & Paivio, 1991) dual coding theory as an explanation for the effects of multimedia on learning. The paper describes dual coding theory, then examines ...
    • Dynamic Door Displays 

      Nguyen, David H.; Tullio, Joseph; Drewes, Tom; Mynatt, Elizabeth D. (Georgia Institute of Technology, 2000)
      Traditionally, office doors have been used as display surfaces for communicating a variety of information between door owners and visitors. While flexible, doors also burden their owners with the task of maintenance and ...
    • Dynamic Simulation of Splashing Fluids 

      O'Brien, James F.; Hodgins, Jessica K. (Georgia Institute of Technology, 1994)
      In this paper we describe a method for modeling the dynamic behavior of splashing fluids. The model simulates the behavior of a fluid when objects impact or float on its surface. The forces generated by the objects create ...
    • Dynapack: Space-Time Compression of the 3D Animations of Triangle Meshes with Fixed Connectivity 

      Ibarria, Lorenzo (Lawrence); Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2003)
      Dynapack exploits space-time coherence to compress the consecutive frames of the 3D animations of triangle meshes of constant connectivity. Instead of compressing each frame independently (space-only compression) or ...
    • EasySLAM 

      Fathi, Alireza; Cunningham, Alex; Paluri, Balmanohar; Ni, Kai; Dellaert, Frank (Georgia Institute of Technology, 2010)
      EasySLAM is a robust, accurate, efficient and easy-to-use visual SLAM framework which uses the unique properties of planar landmarks to navigate robots in societal settings. Due to the use of landmarks which can be ...
    • Edge-Sharpener: Recovering Sharp Features in Triangulations of Non-adaptively Re-meshed Surfaces 

      Attene, Marco; Falcidieno, B. (Bianca); Rossignac, Jaroslaw R.; Spagnuolo, Michela (Georgia Institute of Technology, 2003)
      3D scanners, iso-surface extraction procedures, and several recent geometric compression schemes sample surfaces of 3D shapes in a regular fashion, without any attempt to align the samples with the sharp edges and corners ...
    • Edgebreaker on a Corner Table: A Simple Technique for Representing and Compressing Triangulated Surfaces 

      Rossignac, Jaroslaw R.; Safanova, Alla; Szymczak, Andrzej (Georgia Institute of Technology, 2001)
      A triangulated surface S with V vertices is sometimes stored as a list of T independent triangles, each described by the 3 floating-point coordinates of its vertices. This representation requires about 576V bits and provides ...
    • Edgebreaker: A Simple Compression for Surfaces with Handles 

      Rossignac, Jaroslaw R.; Lopes, Helio; Safanova, Alla; Tavares, Geovan; Szymczak, Andrzej (Georgia Institute of Technology, 2002)
      The Edgebreaker is an efficient scheme for compressing triangulated surfaces. A surprisingly simple implementation of Edgebreaker has been proposed for surfaces homeomorphic to a sphere. It uses the Corner-Table data ...
