      We discuss the linear dispersive properties of finite one-dimensional photonic band-gap structures. We introduce the concept of a complex effective index for structures of finite length, derived from a generalized dispersion ...
    • Communicating neural network knowledge between agents in a simulated aerial reconnaissance system 

      Quirolgico, Stephen; Canfield, Kip; Finin, Timothy; Smith, James A. (IEEE, 1999-10-03)
      In order to maintain their performance in a dynamic environment, agents may be required to modify their learning behavior during run-time. If an agent utilizes a rule-based system for learning, new rules may be easily ...

      Cost, R. Scott; Finin, Tim; Labrou, Yannis; Luan, Xiaocheng; Peng, Yun; Soboroff, Ian; Mayfield, James; Boughannam, Akram (IEEE, 1999-10-03)
      Jackal is a Java-based tool for communication using the KQML agent communication language. Some features that make it extremely valuable to agent development are its conversation management facilities, flexible, blackboard ...
    • Relational Clustering Based on a New Robust Estimator with Application to Web Mining 

      Nasraoui, Olfa; Krishnapuram, Raghu; Joshi, Anupam (IEEE, 1999-10-24)
      Mining typical user profiles and URL associations from the vast amount of access logs is an important component of Web personalization. In this paper, we define the notion of a ""user session" as being a temporally compact ...
    • On Mining Web Access Logs 

      Joshi, Anupam; Joshi, Karuna; Krishnapuram, Raghu (1999-10-24)
