  • Robust fault detection of non-linear systems using set-membership state estimation based on constraint satisfaction 

    Tornil Sin, Sebastián; Ocampo-Martínez, Carlos; Puig Cayuela, Vicenç; Escobet Canal, Teresa (Elsevier, 2012-02)
    Article
    Open Access
    In this paper, the robust fault detection problem for non-linear systems considering both bounded parametric modelling errors and measurement noises is addressed. The non-linear system is monitored by using a state estimator ...
  • Enhanced equal frequency partition method for the identification of a water demand system 

    Escobet Canal, Antoni; Huber Garrido, Rafael M.; Nebot Castells, M. Àngela; Cellier, François E. (Sarjoughian,H.S.; Cellier, F.E.; Marefat, M.M.; Rozenblit, J.W. (eds.) Institute of Electrical and Electronics Engineers, 2000)
    Conference report
    Open Access
    This paper deals with unsupervised partitioning. A first goal of this paper is to present an enhancement to the Equal Frequency Partition (EFP) method that allows to reduce, to some extent, the main drawback of this classical ...
  • Gas film heat transfer as enhancement strategy for phase change materials 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (Wiley (John Wiley & Sons), 2019-10-16)
    Article
    Restricted access - publisher's policy
    In this work, consideration is given to an alternative strategy for phase change materials (PCMs) heat transfer enhancement with particular reference to horizontal plates. In contrast with current approaches in which heat ...
  • On the feasibility of ocean brine pool power stations 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-10-22)
    Article
    Restricted access - publisher's policy
    The demonstrated existence of vast brine pools in a number of places in the ocean basin around the world offers an interesting opportunity to the production of power from ocean, which has not been yet considered. The ...
  • An estimate for thermal osmotic heat storage using precipitation of common salts 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-09-09)
    Article
    Restricted access - publisher's policy
    In this brief note, a first assessment on the possibilities for thermal osmotic storage by harnessing the thermal dependence of the solubility of common salts as an alternative method to sensible heat storage is discussed. ...
  • The use of compliant surfaces for harvesting energy from water streams 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-09-13)
    Article
    Restricted access - publisher's policy
    The possibility for hydrokinetic energy harvesting from small water streams by using compliant surfaces is considered. The basis of the proposed idea is the deliberate bifurcation of a water stream into two streams separated ...
  • A first estimate for thermal osmotic long storage 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-09-15)
    Article
    Restricted access - publisher's policy
    In this brief note, a first assessment on the possibilities for thermal osmotic storage using the thermal precipitation of aqueous solutions as alternative to sensible heat storage is performed. In a recent study it was ...
  • Pumps condition assessment in water distribution networks 

    Soldevila, Adrià; Blesa Izquierdo, Joaquim; Fernández Canti, Rosa M.; Tornil Sin, Sebastián; Meseguer Amela, Jordi; Puig Cayuela, Vicenç (2018)

  • Slingshot resonance for ocean wave energy conversion 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (Springer, 2019-06-13)
    Article
    Restricted access - publisher's policy
    The slingshot effect and its application to converting ocean wave energy are discussed. It is shown that, owing to the large inertia transported by ocean waves and their periodicity, the slingshot effect can result in the ...
  • Hydrokinetic energy conversion using compliant surfaces 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-05-21)
    Article
    Restricted access - publisher's policy
    In this work, consideration is given for a novel technology based on the use of compliant surfaces (membranes) for hydrokinetic energy conversion (HEC) from residual waters where the use of traditional turbines is either ...
  • Solar thermal panels for small-medium scale air cleaners in major cities 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2019-03-01)
    Article
    Restricted access - publisher's policy
    Air quality in major cities is reaching worrisome levels across the planet owing to large-scale industrialization. As a result, air purification systems are becoming a fertile and emerging field for research. Here, ...
