    Nine cooperating rule-based systems, collectively called AUTOCREW which were designed to automate functions and decisions associated with a combat aircraft's subsystems, are discussed. The organization of tasks within each system is described; performance metrics were developed to evaluate the workload of each rule base and to assess the cooperation between the rule bases. Simulation and comparati... View full abstract»

    Degradation of antenna performance by reflector surface distortion, which lowers gain and increases sidelobe levels, is addressed. Distortion compensation concepts based on the applications of properly matched array feeds are presented. Results of conceptual developments, numerical simulations, and measurement verifications are presented in support of this approach, with particular attention to th... View full abstract»

    Reactive control, a recently emerged paradigm for guiding robots in unstructured and dynamic environments, and related work are reviewed. Pertinent telerobotics research for intelligent navigation is briefly surveyed. A scheme-based reactive control system that allows teleoperators to direct a mobile platform without undue concern for local obstacle avoidance is described. By using an analog of th...
