      Coors, Volker; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2003)
      Delphi is a new geometry-guided predictive compression scheme for squeezing the connectivity of a triangluar mesh. The mesh is traversed using the Edgebreaker state machine. Instead of creating the Edgebreaker clers sequence ...
    • Deriving Software Usage Patterns from Log Files 

      Guzdial, Mark (Georgia Institute of Technology, 1993)
      Log files (discrete recordings of user actions during software use) offer the ability to collect human-computer interaction data on a number of users, over time, while the users are engaged in typical tasks in typical ...
    • Description of Computer Science Higher Education in Sub-Saharan Africa: Initial Explorations

      Many countries in Sub-Saharan Africa (SSA) are in need of technology innovators who are equipped to leverage technologies in locally relevant domains such as health, government and education. To create skilled graduates ...
    • Design and Implementation of a Multimedia Opera 

      Oliverio, James; Pair, Jarrell (Georgia Institute of Technology, 1998)
      While the traditional notion of "opera" describes a production that incorporates musical elements with other art forms and media, the conceptual and technical considerations required to mount an electronic multimedia opera ...
    • The Design and Implementation of the MASTERMIND Toolkit (MMTK) 

      Stirewalt, R. E. Kurt (Georgia Institute of Technology, 1997)
      The MASTERMIND project is concerned with the design, integration, and automatic generation of interactive systems from declarative models. One model describes the tasks a user will perform as a protocol of end user actions ...
    • The Design and Use of a Generic Context Server 

      Salber, Daniel; Abowd, Gregory D. (Georgia Institute of Technology, 1998)
      Although context awareness is a key component for perceptual user interfaces, we lack generic infrastructure for developing context aware applications. We propose a generic infrastructure based on context servers that ...
    • Designing a Cognitive Aid for the Home: A Case-Study Approach 

      Paradise, Jessica; Mynatt, Elizabeth D.; Williams, Cliff; Goldthwaite, J. R., III (John R.) (Georgia Institute of Technology, 2004)
      Cognitive impairments play a large role in the lives of surviviors of mild traumatic brain injuries who are unable to return to their prior level of independence in their homes. Computational support has the potential to ...
    • Designing and processing parametric models of steady lattices 

      Gupta, Ashish; Kurzeja, Kelsey; Rossignac, Jarek; Allen, George; Kumar, Pranav Srinivas; Musuvathy, Suraj (2018)
      Our goal is to facilitate the design, analysis, optimization, and additive manufacturing of a specific class of 3D lattices that may comprise an extremely large number of elements. We target curved lattices that exhibit ...
    • Designing for Civil Conversations: Lessons Learned from ChangeMyView 

      Jhaver, Shagun; Vora, Pranil; Bruckman, Amy (Georgia Institute of Technology, 2017-12-12)
      Research has shown that people all over the world, and particularly Americans, are divided over many issues – from immigration and gun control to economic and foreign policy. Information bubbles further contribute to these ...
