      Three dimensional packaging is becoming a popular concept because of the numerous advantages it has to offer over the existing conventional technologies. System on Packages (SOP) is an example of three dimensional packaging. ...
    • Software Behavior: Automatic Classification and its Applications 

      Bowring, James Frederick; Rehg, James Matthew; Harrold, Mary Jean (Georgia Institute of Technology, 2003)
      A program's behavior is ultimately the collection of all its executions. This collection is diverse, unpredictable, and generally unbounded. Thus it is especially suited to statistical analysis and machine learning techniques. ...
    • Automatic Verification of Safety and Liveness for XScale-Like Processor Models Using WEB-Refinements 

      Manolios, Panagiotis; Srinivasan, Sudarshan Kumar (Georgia Institute of Technology, 2003)
