      Distributed diagnosis using predetermined synchronization strategies in the presence of communication constraints 

      Keroglou, C.; Hadjicostis, Christoforos N. (IEEE Computer Society, 2015)
      We consider distributed fault diagnosis in a discrete event system modeled as a nondeterministic finite automaton that is observed at multiple observation sites through distinct natural projection maps. The majority of ...

      Distributed Fault Diagnosis in Discrete Event Systems via Set Intersection Refinements 

      Keroglou, C.; Hadjicostis, Christoforos N. (2018)
      We extend and verify diagnosability for a class of set intersection refinement strategies, which can be used for distributed state estimation and fault diagnosis in nondeterministic finite automata that are observed at ...

      Synchronization and control methods for advancing the grid side converter of Renewable Energy Sources 

      Hadjidemetriou, Lenos C. (Πανεπιστήμιο Κύπρου, Πολυτεχνική Σχολή / University of Cyprus, Faculty of Engineering, 2016-05)
      Η αύξηση στην τιμή καθώς και το περιβαλλοντικό αντίκτυπο των ορυκτών καυσίμων έχουν εγείρει το ενδιαφέρον για τις Ανανεώσιμες Πηγές Ενέργειας (ΑΠΕ), ειδικά όσο αφορά τις ανεμογεννήτριες και τα φωτοβολταϊκά συστήματα. Η ...

      Synchronization-based fault detection in discrete event systems 

      Athanasopoulou, E.; Hadjicostis, Christoforos N. (2004)
      In this paper we study fault detection in systems that can be modeled as finite state machines (FSMs). We aim at detecting faults that manifest themselves as permanent changes in the next-state transition functionality of ...
