    • Dynamic observability method for durability assessment considering measurement noise 

      Peng, Tian; Casas Rius, Joan Ramon; Turmo Coderque, José (2020)
      Text en actes de congrés
      Accés obert
      Due to the inevitable degradation of material properties in structures in daily use, such as stiffness degradation due to cracking in concrete elements, their durability will definitely be influenced, and their serviceability ...

    • Ice thickness effects on Aquarius brightness temperatures over Antarctica 

      Pablos Hernández, Miriam; Piles Guillem, Maria; Gonzalez Gambau, Verónica; Camps Carmona, Adriano José; Vall-Llossera Ferran, Mercedes Magdalena (2015-04-01)
      Article
      Accés obert
      The Dome-C region, in the East Antarctic Plateau, is regarded as an ideal natural laboratory for calibration/validation of space-borne microwave radiometers. At L-band, the thermal stability of this region has been confirmed ...

    • Nonconforming discretization of the electric-field integral equation for closed perfectly conducting objects 

      Úbeda Farré, Eduard; Rius Casals, Juan Manuel; Heldring, Alexander (2014-08-01)
      Article
      Accés restringit per política de l'editorial
      Galerkin implementations of the method of moments (MoM) of the electric-field integral equation (EFIE) have been traditionally carried out with divergence-conforming sets. The normal-continuity constraint across edges gives ...

    • Role of sensors in error propagation with the dynamic constrained observability method 

      Peng, Tian; Nogal Macho, María; Casas Rius, Joan Ramon; Turmo Coderque, José (Multidisciplinary Digital Publishing Institute (MDPI), 2021-05)
      Article
      Accés obert
      The inverse problem of structural system identification is prone to ill-conditioning issues; thus, uniqueness and stability cannot be guaranteed. This issue tends to amplify the error propagation of both the epistemic and ...

    • Time-domain statistics of the electromagnetic bias in GNSS-reflectometry 

      Ghavidel, Ali; Camps Carmona, Adriano José (2015-09-01)
      Article
      Accés obert
      Global Navigation Satellite Systems-Reflectometry (GNSS-R) is an emerging remote sensing technique that uses navigation signals reflected on the Earth's surface as sources of opportunity for scatterometry and altimetry. ...
