      Leakages are a relevant issue in water distribution networks with severe effects on costs and water savings. While there are several solutions for detecting leakages by analyzing of the minimum night flow and the pressure ...
    • An ensemble approach to estimate the fault-time instant 

      Alippi, Cesare; Boracchi, Giacomo; Puig Cayuela, Vicenç; Roveri, Manuel (2013)
      Conference report
      Open Access
      Since systems are prone to faults, fault detection and isolation are essential activities to be considered in safety-critical applications. In this direction, the availability of a sound estimate of the time instant the ...
    • Model- vs. data-based approaches applied to fault diagnosis in potable water supply networks 

      Cugueró, Miquel Àngel; Quevedo Casín, Joseba Jokin; Alippi, Cesare; Roveri, Manuel; Puig Cayuela, Vicenç; García Valverde, Diego; Trovò, F (2016-05-10)
      Article
      Open Access
      In this paper, the problem of fault diagnosis in drinking water transport networks (DWTNs) is addressed. Two different fault diagnosis approaches are proposed to deal with this problem. The first one is based on a ...
    • Temporal/spatial model-based fault diagnosis vs. hidden Markov models change detection method: application to the Barcelona water network 

      Quevedo Casín, Joseba Jokin; Alippi, Cesare; Cugueró Escofet, Miquel Àngel; Ntalampiras, Stavros; Puig Cayuela, Vicenç; Roveri, Manuel; García Valverde, Diego (2013)
