  • Jervis, Barrie; Belal, Suliman; Camilleri, Kenneth P.; Camilleri, Tracey; Fabri, Simon G.; Linden, David E. J.; Michalopoulos, Kostas; Zervakis, Michalis; Bigan, Cristin; Besleaga, Mircea (CIMED, 2007-07)
    The Independent Components (ICs) of P300 and CNV Evoked Potentials (EPs) have been found on a truly single trial basis using Independent Component Analysis (ICA) and cluster analysis. P300 data was obtained from ...
  • Cassar, Tracey A.; Camilleri, Kenneth P.; Fabri, Simon G.; Zervakis, Michalis; Micheloyannis, Sifis (Institute of Electrical and Electronics Engineers Inc., 2008)
    Parametric models are widely used for EEG data analysis. In this experimental study an autoregressive moving average (ARMA) model was used to extract spectral features within defined frequency bands which were ...
  • Camilleri, Tracey A.; Camilleri, Kenneth P.; Fabri, Simon G. (Elsevier Ltd., 2014)
    This work investigates the use of switching linear Gaussian state space models for the segmentation and automatic labelling of Stage 2 sleep EEG data characterised by spindles and K-complexes. The advan- tage of this ...

    Background: In this work we consider hidden signs (biomarkers) in ongoing EEG activity expressing epileptic tendency, for otherwise normal brain operation. More specifically, this study considers children with ...
  • Mifsud, Nathaniel; Grech, A. M.; Saliba, Michael; Fabri, Simon G. (VDI-Wissensforum-IWB-GmbH, 2006)
    In this work, we report on the mechanical design and development, the kinematic analysis, and the simulation of a new dexterous robot finger. The robot finger design is based on that of the human counterpart in size, ...
  • Fabri, Simon G.; Kadirkamanathan, Visakan (IFAC, 1998)
    A neural-adaptive control system for a class of discrete-time nonlinear plants is proposed. Neural networks and adaptation are required to ensure stability and asymptotic convergence of the tracking error, in spite of the ...
  • Bugeja, Marvin K.; Fabri, Simon G. (Institute of Electrical and Electronics Engineers, 2007)
    This paper presents a novel dual adaptive dynamic controller for trajectory tracking of nonholonomic wheeled mobile robots. The controller is developed entirely in discretetime and the and the robot’s nonlinear dynamic ...
  • Fabri, Simon G. (The European Control Association (EUCA), 2015)
    Dual control laws offer important advantages for adaptive systems. The majority of dual control publications consider only discrete-time systems. This paper proposes a novel dual adaptive controller for n th order, ...
  • Fabri, Simon G.; Kadirkamanathan, Visakan (Pergamon Press, 1998)
    A suboptimal dual adaptive system is developed for control of stochastic, nonlinear, discrete-time plants that are affine in the control input. The nonlinear functions are assumed to be unknown and neural networks are used ...
