• Backbone formation in military multi-layer ad hoc networks using complex network concepts 

      Papakostas D., Basaras P., Katsaros D., Tassiulas L. (2016)
      Modern battlefields are characterized by increasing deployment of ad hoc communications among allied entities. These networks can be seen as a complex multi-layer ad hoc network, where each layer may be an independently ...
    • Noninteracting control for helicopter in straight horizontal flight 

      Koumboulis, F. N.; Skarpetis, M. G.; Griparis, M. K. (1998)
      Pitch angle and forward velocity are decoupled via a static state feedback law for the case of helicopter in straight horizontal flight. The set of stability derivatives for which decoupling is satisfied, is explicitly ...
    • Rotary gust rejection for helicopters 

      Koumboulis, F. N.; Skarpetis, M. G.; Griparis, M. K. (1998)
      For the case of helicopters in straight horizontal flight, the effects of a rotary gust to the forward velocity and the downward velocity of the helicopter are rejected. The rotor commands appear to be independent, i.e. ...
