  • Revision of cancellation at the edge approach for active noise barrier 

    Sohrabi, Shahin; Pàmies Gómez, Teresa; Romeu Garbí, Jordi (2020)
    Conference report

    In most of the investigations, the active noise barriers are configured placing both secondary sources and error sensors close to the edge of barriers, but it is unclear how far is this approach from the maximum theoretical ...
  • A Stiffness-fault-tolerant control strategy for an elastically actuated powered knee orthosis 

    Velasco-Guillen, Rodrigo J.; Grosu, Victor; Carmona Ortiz, Víctor A.; Vanderborght, Bram; Lefeber, Dirk; Font Llagunes, Josep Maria; Beckerle, Philipp (Institute of Electrical and Electronics Engineers (IEEE), 2020)

    Elastic actuators can provide safe human-robot interaction and energy efficient mobility. For this purpose they are ideal for wearable robotic applications. However, such actuators are subject to stiffness faults. We present ...
  • Exoskeleton design using subject-specific synergy-driven neuromusculoskeletal models 

    Arones, Marleny; Font Llagunes, Josep Maria; Fregly, Benjamin Jon (2020)
    Conference report

    Most assistive devices available today are unable to improve gait asymmetries due to the lack of knowledge on how to directly enforce kinematic symmetry in the formulation of cost functions. We designed a cost function to ...
  • Technology developments for an advanced L-band radiometer mission 

    Martín Neira, Manuel; Catalán Artigas, Albert; Corbella Sanahuja, Ignasi; Durán Martínez, Israel; Duffo Ubeda, Núria (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference lecture
    Open Access
    ESA’s Soil Moisture and Ocean Salinity (SMOS) mission was launched 2 Nov 2009 and, to date, is still in good health, providing valuable L-band observations of the Earth surface [1]. A number of products are obtained from ...
  • Investigate the effect of the active noise barrier on the reduction of noise level at the shadow zone and the neighboring building 

    Sohrabi, Shahin; Pàmies Gómez, Teresa; Romeu Garbí, Jordi (Institute of Noise Control Engineering, 2020)
    Conference report
    Restricted access - publisher's policy
    Barriers are among the most widely used strategy to control the ambient noise in the urban areas. However, the previous studies approve the inefficiency of the barriers to degrade low-frequency spectra noise. The technique ...
  • Efficiency of isolated concrete blocks applied in railway slab tracks as mitigation measures for railway-induced ground-borne vibration in tunnels 

    Arcos Villamarín, Robert; Liravi, Hassan; Ghangale, Dhananjay; Romeu Garbí, Jordi (Institute of Noise Control Engineering, 2020)
    Conference report

    This paper presents a study of the efficiency of isolated concrete blocks as vibration mitigation measures for railway-induced ground-borne vibration problems in subway metro tunnels. The study is performed numerically, ...
  • VIBWAY: A prediction toolbox for railway induced ground-borne vibrations 

    Noori, Behshad; Arcos Villamarín, Robert; Clot Razquin, Arnau; Cardona Gonyalons, Joan; Romeu Garbí, Jordi (Institute of Noise Control Engineering, 2020)
    Conference report
    Restricted access - publisher's policy
    This paper aims to introduce a computationally efficient and user-friendly toolbox, called VIBWAY, able to predict vibration levels that a future railway line, either at-grade or underground, will generate on its nearby ...
  • Experimental validation of a hybrid FE-SEA-experimental model 

    Clot Razquin, Arnau; Meggitt, J.W.R.; Langley, Robin; Moorhouse, Andy; Elliott, Andrew (Institute of Noise Control Engineering, 2020)
    Conference report
    Restricted access - publisher's policy
    Modern manufacturers usually need to know at a design stage if their products will meet certain vibro-acoustic requirements. In many cases the use of physical prototyping becomes significantly expensive, and engineers opt ...
  • Uncertainty assessment of a model to predict the vibration induced by train traffic in tunnels 

    Latorre Iglesias, Eduardo; Arcos Villamarín, Robert (Institute of Noise Control Engineering, 2020)
    Conference report
    Restricted access - publisher's policy
    The uncertainty assessment of ground-borne noise and vibration predictions is important to reduce risks when decisions are made based on simulation results. In addition, it provides robustness to the prediction framework ...
  • On the use of experimental ensembles in a hybrid deterministic-statistical energy analysis method 

    Clot Razquin, Arnau; Langley, Robin; Meggitt, J.W.R.; Moorhouse, Andy; Elliott, Andrew (2020)
    Conference report
    Restricted access - publisher's policy
    There is a clear need in modern industries for models that can predict the vibro-acoustic response of their manufactured products at the design stage. Models based on the hybrid deterministic-statistical method are a ...
  • A methodology for the assessment of underground railway-induced vibrations based on radiated energy flow computed by means of a 2.5D FEM-BEM approach 

    Ghangale, Dhananjay; Arcos Villamarín, Robert; Clot Razquin, Arnau; Romeu Garbí, Jordi (Springer, 2019)
