  • The brinesiphon: a homolog of the thermosiphon driven by induced salinity and downward heat transfer 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2017-09-01)
    Article
    Accés restringit per política de l'editorial
    The basis of a novel method for passive solar water heating homologous to the thermosiphon but driven by induced salinity, which causes a fluid to circulate without the need for a mechanical pump and with inverse natural ...
  • Use of hydrodynamic cavitation for volatile removal compound 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2017-05-18)
    Article
    Accés restringit per política de l'editorial
    Hydrodynamic cavitation and its feasibility for volatile compound removal in enclosed channels is discussed in this paper. Very high Reynolds numbers are needed to rupture liquid by decreasing its pressure below its saturated ...
  • Leak localization in water distribution networks using a mixed model-based/data-driven approach 

    Soldevila Coma, Adrià; Tornil Sin, Sebastián; Blesa Izquierdo, Joaquim; Duviella, Eric; Fernández Canti, Rosa M.; Puig Cayuela, Vicenç (2016-10-01)
    Article
    Accés obert
    This paper proposes a new method for leak localization in water distribution networks (WDNs). In a first stage, residuals are obtained by comparing pressure measurements with the estimations provided by a WDN model. In a ...
  • Modeling and robust low level control of an omnidirectional mobile robot 

    Comasòlivas Font, Ramon; Quevedo Casín, Joseba Jokin; Escobet Canal, Teresa; Escobet Canal, Antoni; Romera Formiguera, Juli (2017-04-01)
    Article
    Accés restringit per política de l'editorial
    This paper presents the modeling and robust low-level control design of a redundant mobile robot with four omnidirectional wheels, the iSense Robotic (iSRob) platform, that was designed to test safe control algorithms. ...
  • Data analytics methodology for monitoring quality sensors and events in the Barcelona drinking water network 

    García Valverde, Diego; Creus Rodriguez, Ramon; Minoves Ruiz, Meritxell; Pardo, Xavier; Quevedo Casín, Joseba Jokin; Puig Cayuela, Vicenç (2017-01-01)
    Article
    Accés obert
    Water quality management is a key area to guarantee drinking water safety to users. This task is based on disinfection techniques, such as chlorination, applied to the drinking water network to prevent the growth of ...
  • Data Validation and reconstruction for performance enhancement and maintenance of water networks 

    Quevedo Casín, Joseba Jokin; Pascual Pañach, Josep; Espin, Santiago; Roquet, Jaume (2016-01-01)
    Article
    Accés obert
    In a real water network, a telecontrol system must periodically acquire, store and validate data gathered by sensor measurements in order to achieve accurate monitoring of the whole network in real time. For each sensor ...
  • Actuator multiplicative fault estimation in discrete-time LPV systems using switched observers 

    Rotondo, Damiano; López Estrada, Francisco Ronay; Nejjari Akhi-Elarab, Fatiha; Ponsart, J. C.; Theilliol, Didier; Puig Cayuela, Vicenç (2016-09-01)
    Article
    Accés restringit per política de l'editorial
    This paper proposes an observer for the joint state and fault estimation devoted to discrete-time linear parameter varying (LPV) systems subject to actuator faults. The major contribution of this work is that the observer ...
  • 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
    Accés obert
    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 ...
  • On teaching model-based fault diagnosis in engineering curricula 

    Costa Castelló, Ramon; Puig Cayuela, Vicenç; Blesa Izquierdo, Joaquim (2016-02-01)
    Article
    Accés obert
    This article presents an example of how a fault-diagnosis course has been included in an engineering curricula in a motivating way, in particular, in the automatic control and robotic master's degree program at UPC. This ...
  • Robust unknown input observer for state and fault estimation in discrete-time Takagi-Sugeno systems 

    Rotondo, Damiano; Witczak, Marcin; Puig Cayuela, Vicenç; Nejjari Akhi-Elarab, Fatiha; Pazera, Marcin (2016-01-01)
    Article
    Accés obert
    In this paper, a robust unknown input observer (UIO) for the joint state and fault estimation in discrete-time Takagi-Sugeno (TS) systems is presented. The proposed robust UIO, by applying the H-infinity framework, leads ...
