      Active Contamination Detection in Water-Distribution Systems 

      Vrachimis, Stelios G.; Lifshitz, Ron; Eliades, Demetrios G.; Polycarpou, Marios M.; Ostfeld, Avi (2020)
      In this paper, we propose a novel methodology for altering the area monitored by water quality sensors in water distribution systems (WDS) when there is suspicion of a contamination event. The proposed active contamination ...

      Real-time state estimation and fault diagnosis of water distribution systems 

      Vrachimis, Stelios G. (Πανεπιστήμιο Κύπρου, Πολυτεχνική Σχολή / University of Cyprus, Faculty of Engineering, 2020-08)
      Οι σύγχρονες κοινωνίες αρχίζουν να συνειδητοποιούν τη σημασία του πόσιμου νερού λόγω της λειψυδρίας σε πολλά μέρη του κόσμου ως αποτέλεσμα του αυξανόμενου ανθρώπινου πληθυσμού και της κλιματικής αλλαγής. Η βιομηχανία ...
