    • Self-sensing concrete made from recycled carbon fibres 

      Segura Pérez, Ignacio; Faneca Llesera, Gerard; Torrents Dolz, Josep M.; Aguado de Cea, Antonio (2019-10)
      Article
      Accés obert
      The electrical and piezo-resistive responses of recycled carbon fibre (rCF)-reinforced concrete is analysed in this article. Two different PAN-based rCFs (monofilament rCF and fibrillated rCF sheets) incorporated into dry ...

    • Subsurface resistivity measurements using square waveforms 

      Gasulla Forner, Manuel; Jordana Barnils, José; Pallàs-Areny, Ramon; Torrents Dolz, Josep M. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-02-28)
      Article
      Accés obert
      This work analyzes the effect of inductive and capacitive coupling between the injecting circuit and the detecting circuit in resistive field surveys. Theoretical and experimental results demonstrate that if a square ...

    • Surveillance of steel fibre reinforced concrete slabs measured with an open-ended coaxial probe 

      Torrents Dolz, Josep M.; Juan Garcia, Pablo; Patau, Oriol; Aguado de Cea, Antonio (2009)
      Text en actes de congrés
      Accés obert
      Conventional concrete structures are nowadays being substituted by steel fibre reinforced concrete (SFRC) in some structural applications. Then, fibre dosage and distribution is a keyword for ensuring quality control of ...

    • The floating capacitor as a differential building block 

      Gasulla Forner, Manuel; Jordana Barnils, José; Pallàs-Areny, Ramon; Torrents Dolz, Josep M. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-02-28)
      Article
      Accés obert
      This paper analyzes the advantages and limitations of using the floating- (or flying-) capacitor technique as a building block with differential input and either differential or single-ended output to implement voltage ...

    • Uncertainty analysis in two-terminal impedance measurements with residual correction 

      Torrents Dolz, Josep M.; Pallàs-Areny, Ramon (Institute of Electrical and Electronics Engineers, 2001-05)
      Text en actes de congrés
      Accés obert
      Residual impedance correction in impedance analyzers when using an asymmetrical test fixture needs three reference measurements, usually open circuit, short circuit, and load (meaning an impedance close to the impedance ...
