  • Ceramic macromembrane for tangento-axial micro- and ultrafiltration water systems 

    Cusidó Fàbregas, Joan Antoni; Cremades Oliver, Lázaro Vicente; Sitjar Cañellas, Rafael (2016-02-01)
    Article
    Accés obert
    An innovative proposal of tangento-axial filtration based on the concept of macromembrane (large size) is presented in the context of micro- and ultrafiltration ceramic membranes. The macromembrane is made of Al2O3–TiO2 ...
  • Dynamical models of a wire scanner 

    Barjau Condomines, Ana; Herranz Álvarez, Juan Francisco; Dehning, Bernd (2016-10-01)
    Article
    Accés restringit per política de l'editorial
    The accuracy of the beam profile measurements achievable by the current wire scanners at CERN is limited by the vibrations of their mechanical parts. In particular, the vibrations of the carbon wire represent the major ...
  • Estimation of muscular forces from SSA smoothed sEMG signals calibrated by inverse dynamics-based physiological static optimization 

    Romero Sánchez, Francisco; Alonso Sánchez, Francisco Javier; Gragera, C.; Lugrís Armesto, Urbano; Font Llagunes, Josep Maria (2016-12-01)
    Article
    Accés restringit per política de l'editorial
    The estimation of muscular forces is useful in several areas such as biomedical or rehabilitation engineering. As muscular forces cannot be measured in vivo non-invasively they must be estimated by using indirect measurements ...
  • Traumatic brain injury in pedestrian–vehicle collisions: Convexity and suitability of some functionals used as injury metrics 

    Sánchez Molina, David; Arregui Dalmases, Carlos; Velázquez Ameijide, Juan; Angelini, Massimo; Kerrigan, Jason; Crandall, Jeff R. (2016-11-01)
    Article
    Accés obert
    Background and Objective: Abrupt accelerations or decelerations can cause large strain in brain tissues and, consequently, different forms of Traumatic Brain Injury (TBI). In order to predict the effect of the accelerations ...
  • Aplicación de la emisión acústica como método para anticipar el fallo de tejidos colaginosos (1ª parte) 

    García Vilana, Silvia; Martínez González, Eva; Sánchez Molina, David; Arregui Dalmases, Carlos; Velázquez Ameijide, Juan; Llumà Fuentes, Jordi; Rebollo Soria, María Carmen (2016-07-01)
    Article
    Accés obert
    Se usa un montaje experimental basado en Emisión Acústica (EA) para detectar la energía elástica liberada durante el proceso de tracción y rotura de tejidos colaginosos. Se localizan las señales y se cuenta el número de ...
  • Dynamic response of a double-deck circular tunnel embedded in a full-space 

    Clot Razquin, Arnau; Arcos Villamarín, Robert; Romeu Garbí, Jordi; Pàmies Gómez, Teresa (2016-10-01)
    Article
    Accés restringit per política de l'editorial
    A three-dimensional dynamic model for calculating the ground-borne vibrations generated by harmonic loads applied on the interior floor of a double-deck circular tunnel is developed. The response of the system is obtained ...
  • Influence of the controller design on the accuracy of a forward dynamic simulation of human gait 

    Pàmies Vila, Rosa; Pätkau, Olga; Dòria Cerezo, Arnau; Font Llagunes, Josep Maria (2017-01)
    Article
    Accés restringit per política de l'editorial
    The analysis of a captured motion can be addressed by means of forward or inverse dynamics approaches. For this purpose, a 12 segment 2D model with 14 degrees of freedom is developed and both methods are implemented using ...
  • An energy flow study of a double-deck tunnel under quasi-static and harmonic excitations 

    Clot Razquin, Arnau; Romeu Garbí, Jordi; Arcos Villamarín, Robert (2016-10)
    Article
    Accés restringit per política de l'editorial
    This paper presents a comparison between the vibration energy flow radiated by a double-deck tunnel and the one radiated by a simple tunnel when both are excited by constant or by harmonic moving loads. For both cases, the ...
  • Assessment of environmental noise and its effect on neonates in a Neonatal Intensive Care Unit 

    Romeu Garbí, Jordi; Cotrina, Laura; Perapoch, Josep; Linés, Marcos (2016-10-01)
    Article
    Accés obert
    A method for analyzing the influence of noise on newborns is proposed. The method consists of defining three different types of time interval (quiet, noisy and nursing) and, for each period, environmental noise levels, ...
  • The use of rapid prototyping techniques (RPT) to manufacture micro channels suitable for high operation pressures and uPIV 

    Farré Lladós, Josep; Casals Terré, Jasmina; Voltas Aguilar, Jordi; G. Westerberg, Lars (2016)
    Article
    Accés obert
    This paper aims to present a new methodology to manufacture micro-channels suitable for high operating pressures and micro particle image velocimetry (µPIV) measurements using a rapid-prototyping high-resolution 3D printer. ...
