  • Energy management strategy for fuel cell-supercapacitor hybrid vehicles based on prediction of energy demand 

    Carignano, Mauro; Costa Castelló, Ramon; Roda Serrat, Vicente; Nigro, Norberto; Junco, Sergio; Feroldi, Diego Hernan (2017-08-31)
    Article
    Accés restringit per política de l'editorial
    Offering high efficiency and producing zero emissions Fuel Cells (FCs) represent an excellent alternative to internal combustion engines for powering vehicles to alleviate the growing pollution in urban environments. Due ...
  • Real-time 3D reconstruction of non-rigid shapes with a single moving camera 

    Agudo Martínez, Antonio; Moreno-Noguer, Francesc; Calvo, Begoña; Martinez Montiel, José Maria (2016)
    Article
    Accés obert
    This paper describes a real-time sequential method to simultaneously recover the camera motion and the 3D shape of deformable objects from a calibrated monocular video. For this purpose, we consider the Navier-Cauchy ...
  • A bayesian approach to simultaneously recover camera pose and non-rigid shape from monocular images 

    Moreno-Noguer, Francesc; Porta Pleite, Josep Maria (2016)
    Article
    Accés obert
    In this paper we bring the tools of the Simultaneous Localization and Map Building (SLAM) problem from a rigid to a deformable domain and use them to simultaneously recover the 3D shape of non-rigid surfaces and the sequence ...
  • Sensor localization from distance and orientation constraints 

    Porta Pleite, Josep Maria; Rull Sanahuja, Aleix; Thomas, Federico (2016)
    Article
    Accés obert
    The sensor localization problem can be formalized using distance and orientation constraints, typically in 3D. Local methods can be used to refine an initial location estimation, but in many cases such estimation is not ...
  • A 3D descriptor to detect task-oriented grasping points in clothing 

    Ramisa Ayats, Arnau; Alenyà Ribas, Guillem; Moreno-Noguer, Francesc; Torras, Carme (2016)
    Article
    Accés obert
    Manipulating textile objects with a robot is a challenging task, especially because the garment perception is difficult due to the endless configurations it can adopt, coupled with a large variety of colors and designs. ...
  • Nonlinear predictive control for durability enhancement and efficiency improvement in a fuel cell power system 

    Luna Pacho, Julio Alberto; Jemei, Samir; Yousfi-Steiner, Nadia; Husar, Attila Peter; Serra, Maria; Hissel, Daniel (2016)
    Article
    Accés obert
    In this work, a nonlinear model predictive control (NMPC) strategy is proposed to improve the efficiency and enhance the durability of a proton exchange membrane fuel cell (PEMFC) power system. The PEMFC controller is based ...
  • 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 ...
  • Nonlinear observation in fuel cell systems: a comparison between disturbance estimation and High-Order Sliding-Mode techniques 

    Luna Pacho, Julio Alberto; Usai, Elio; Husar, Attila Peter; Serra, Maria (2016-11-16)
    Article
    Accés obert
    This paper compares two Nonlinear Distributed Parameter Observers (NDPO) for the observation of a Proton Exchange Membrane Fuel Cell (PEMFC). Both NDPOs are based on the discretisation of distributed parameters models and ...
  • Action recognition based on efficient deep feature learning in the spatio-temporal domain 

    Husain, Syed Farzad; Dellen, Babette Karla Margarete; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Article
    Accés obert
    Hand-crafted feature functions are usually designed based on the domain knowledge of a presumably controlled environment and often fail to generalize, as the statistics of real-world data cannot always be modeled correctly. ...
  • A matrix-based approach to the image moment problem 

    Martínez Bauzà, Judit; Porta Pleite, Josep Maria; Thomas, Federico (2006-11)
    Article
    Accés obert
    An image can be seen as an element of a vector space and hence it can be expressed in as a linear combination of the elements of any non necessarily orthogonal basis of this space. After giving a matrix formulation of this ...
