    In this paper, a seafloor characterization technique to unravel the number of data classes using multibeam echo-sounding backscatter data has been demonstrated. An application of self-organizing maps (SOMs) to backscatter ...
  • Hassani, V.; Sorensen, A.J.; Pascoal, A.M. (Proceeding of 9th IFAC Conference on Control Applications in Marine Systems CAMS 2013, Osaka, Japan, September 17-20, 2013. ed. by: Kazuhiko, H., vol.9; 2013; 203-208)
    This paper addresses a filtering problem that arises in the design of dynamic positioning systems for ships and offshore rigs subjected to the influence of sea waves. The dynamic model of the vessel captures explicitly the ...

    The availability of reliable underwater positioning systems to localize one or more vehicles simultaneously based on information received on-board a support ship or an autonomous surface vessel is key to the operation of ...
  • Teixeira, F.C.; Pascoal, A.M. (Proceeding of 9th IFAC Conference on Control Applications in Marine Systems CAMS 2013, Osaka, Japan, September 17-20, 2013. ed. by: Kazuhiko, H., vol.9; 2013; 239-244)
    This paper proposes novel methods with the potential to improve the performance of navigation and tracking systems in underwater environments. The work relies on well-established methods of potential field inversion and ...

    This paper addresses a filtering problem that arises in the design of dynamic positioning systems for ships and offshore rigs subjected to the influence of sea waves. The vessel`s dynamic model adopted captures the sea ...
  • Rego, F.; Aguiar, A.P.; Pascoal, A.M. (Proceeding of 9th IFAC Conference on Control Applications in Marine Systems (CAMS 2013), Osaka, Japan, September 17-20, 2013. ed. by: Kazuhiko, H., vol.9; 2013; 262-267)
    We introduce an event driven communication logic for decentralized control of a network of robotic vehicles (agents). The strategy proposed is robust to packet losses and drives the vehicles to predefined paths while holding ...
  • Crasta, N.; Bayat, M.; Aguiar, A.P.; Pascoal, A.M. (Proceeding of 9th IFAC Conference on Control Applications in Marine Systems (CAMS 2013), Osaka, Japan, September 17-20, 2013. ed. by: Kazuhiko, H., vol.9; 2013; 227-232)
    We analyze the observability properties of an underwater vehicle (moving in 2D) performing single beacon navigation for two specic classes of maneuvers, whereby the vehicle measures its distance to a xed transponder located ...
