  • Influence of building orientation on the flexural strength of laminated object manufacturing specimens 

    Olivier, Djamila; Travieso Rodriguez, Jose Antonio; Borrós Gómez, Salvador; Reyes Pozo, Guillermo; Jerez Mesa, Ramón (Springer, 2017)
    Article
    Accés obert
    This study aims to define the best building orientation for components produced via the Laminated object manufacturing (LOM) technique to enhance their flexural performance. Results of previous research show that components ...
  • Roughness evolution of previously milled samples along a polishing test 

    Buj Corral, Irene; Vivancos Calvet, Joan (2016-04-03)
    Article
    Accés restringit per política de l'editorial
    In the present work results about roughness evolution along a polishing operation with corundum disks of size Norton 400 are presented. Hardened steel and hardened stainless steel samples were previously subjected to ...
  • Residual stresses induced by honing processes on hardened steel cylinders 

    Buj Corral, Irene; Vivancos Calvet, Joan; Setien, Iñaki; San Sebastian Ormazabal, Maria (2016-06-01)
    Article
    Accés restringit per política de l'editorial
    In the present paper, residual stresses induced by honing processes on hardened steel cylinders were determined. Cubic boron nitride (CBN) abrasives were employed. Both surface measurements and depth profiles were obtained ...
  • A comparative study of elastic motions in trajectory tracking of flexible RPR planar manipulators moving with high speed 

    Firoozabadi, Amirhossein Eshaghiyeh; Ebrahimi, Saeed; Font Llagunes, Josep Maria (2016-05-20)
    Article
    Accés restringit per política de l'editorial
    The study of inertial forces effects at high speeds in flexible parallel manipulators, which generate undesired deviations, is a challenging task due to the coupled and complicated equations of motion. A dynamic model of ...
  • 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 ...
