    • ACDS: Adapting Computational Data Streams for High Performance 

      Isert, Carsten; Schwan, Karsten (Georgia Institute of Technology, 2000)
      Data-intensive, interactive applications are an important class of metacomputing (Grid) applications. They are characterized by large data flows between data providers and consumers, like scientific simulations and remote ...

    • Adaptable Mirroring in Cluster Servers 

      Gavrilovska, Ada; Schwan, Karsten; Oleson, Van (Georgia Institute of Technology, 2001)
      This paper presents a software architecture for continuously mirroring streaming data received by one node of a cluster-based server system to other cluster nodes. The intent is to distribute the server loads implied by ...

    • Adaptation and Specialization for High Performance Mobile Agents 

      Zhou, Dong; Schwan, Karsten (Georgia Institute of Technology, 1998)
      Mobile agents as a new design paradigm for distributed computing potentially permit network applications to operate across dynamic and heterogeneous systems and networks. Agent computing, however, is subject to ...

    • Adaptive and Automated Index Selection in Relational DBMS 

      Frank, Martin Robert; Omiecinski, Edward Robert; Navathe, Shamkant B. (Georgia Institute of Technology, 1994)
      We present a novel approach for a tool that assists the database administrator in designing an index configuration for a relational database system. A new methodology for collecting usage statistics at run time is ...

    • Adaptive MAC Protocol for a Cable Modem 

      Sala, Dolors; Limb, J. O. (John O.); Khaunte, Sunil Upendra (Georgia Institute of Technology, 1997)
      Cable plants were initially designed for one-way broadcast communication (from the head-end to the neighborhood). They are now being upgraded to provide an upstream path (from the home to the head-end). New challenges ...

    • Adding structure to unstructured peer-to-peer networks: the role of overlay topology 

      Merugu, Shashidhar; Srinivasan, Sridhar; Zegura, Ellen W. (Georgia Institute of Technology, 2003)
      Our work examines the role of overlay topology on the performance of unstructured peer-to-peer systems. We focus on two metrics of performance: (a) search protocol performance, a local gain perceived directly by a user ...

    • Advanced Polymorphic Worms: Evading IDS by Blending in with Normal Traffic 

      Kolesnikov, Oleg; Lee, Wenke (Georgia Institute of Technology, 2005)
      Normal traffic can provide worms with a very good source of information to camouflage themselves. In this paper, we explore the concept of polymorphic worms that mutate based on normal traffic. We assume that a worm ...

    • Alphabet Dependence in Parameterized Matching 

      Amir, Amihood; Farach-Colton, Martin; Muthukrishnan, S. (Georgia Institute of Technology, 1993)
      The classical pattern matching paradigm is that of seeking occurrences of one string in another, where both strings are drawn from an alphabet set ∑. A recently introduced model is that of parameterized pattern matching; ...

    • Alternative Object Organizations using Prototypes, Delegation and Split Objects 

      Astudillo R., Hernan; Shilling, John J. (Georgia Institute of Technology, 1993)
      Object-based (i.e. classless) models are very effective for elucidating requirements from users, and they support exploratory programming and rapid prototyping. On the other hand, class-based models are preferred to ...

    • Analysis and Testing of Programs with Exception-Handling Constructs 

      Sinha, Saurabh; Harrold, Mary Jean (Georgia Institute of Technology, 2000)
