  • Measurement of pesticide spray drift with a specifically designed lidar system 

    Gregorio, Eduard; Torrent, Xavier; Planas, Santiago; Solanelles, Francesc; Sanz Cortiella, Ricardo; Rocadenbosch Burillo, Francisco; Masip, Joan; Ribes Dasi, Manel; Rosell Polo, Joan Ramon (2016-04-08)
    Article
    Open Access
    Field measurements of spray drift are usually carried out by passive collectors and tracers. However, these methods are labour- and time-intensive and only provide point- and time-integrated measurements. Unlike these ...

    Font Bach, Oriol; Bartzoudis, Nikolaos; Pascual Iserte, Antonio; Payaró Llisterri, Miquel; Blanco, Luis; López Bueno, David; Molina Pena, Marc (Wiley-Blackwell, 2015)
    Article
    Open Access
    Interference is a major obstacle in radio communications, especially when opportunistic frequency reuse is an inherent requirement for maximising spectral ef¿ciency in heterogeneous networks. A typical example is encountered ...

    Article
    Restricted access - publisher's policy
    In this work the active tomographic imaging of biological bodies which exhibits a high dielectric contrast is studied. Two approaches based on the Born approximation are presented: a differential reconstruction method which ...
  • A General approach for the calculation of intermodulation distortion in cavities with superconducting endplates 

    Mateu Mateu, Jordi; Collado Gómez, Juan Carlos; Menéndez, O; O'Callaghan Castellà, Juan Manuel (2003-01)
    Article
    Open Access
    We report on a general procedure to calculate intermodulation distortion in cavities with superconducting endplates that is applicable to the dielectric-loaded cavities currently used for measurement of surface resistance ...
  • General electromagnetic simulation tool to predict the microwave nonlinear response of planar, arbitrarily-shaped HTS structures 

    Parrón Granados, Josep; Collado Gómez, Juan Carlos; Mateu Mateu, Jordi; Rius Casals, Juan Manuel; Duffo Ubeda, Núria; O'Callaghan Castellà, Juan Manuel (2001-03)
    Article
    Open Access
    This work describes a simulation tool being developed at UPC to predict the microwave nonlinear behavior of planar superconducting structures with very few restrictions on the geometry of the planar layout. The software ...
  • Nonlinear Analysis of Disk Resonators: Application to Material Characterization and Filter Design 

    Mateu Llevadot, Jordi; O'Callaghan Castellà, Juan Manuel (2001-05)
    Article
    Open Access
    A procedure for the numerical prediction of the microwave nonlinear behavior (intermodulation products, degradation of quality factors, etc.) of TM010 disk resonators has been developed. The procedure is based on relating ...
  • Direct identification of extended defects as vortex pinning centers in melt textured YBa/sub 2/Cu/sub 3/O/sub 7/-Y/sub 2/BaCuO/sub 5/ composites 

    Puig Molina, Teresa; Obradors i Berenguer, Francesc Xavier; Martinez, B; Sandiumenge, F; O'Callaghan Castellà, Juan Manuel; Rabier, J (1999-06)
    Article
    Open Access
    Single domain YBa/sub 2/Cu/sub 3/O/sub 7/-Y/sub 2/BaCuO/sub 5/ melt textured ceramic composites have revealed a very rich microstructure, which has usually impeded, by using standard measurements, to evaluate the contribution ...
  • Numerical Optimization of Hybrid Dielectric/HTS Resonator for Surface Impedance Evaluation of HTS Films 

    Collado Gómez, Juan Carlos; Gonzalo, D; Rozan, E; O'Callaghan Castellà, Juan Manuel (1999-06)
    Article
    Open Access
    This work describes an alternative to the traditional dielectric resonator topology used for measuring surface impedance in high temperature superconducting (HTS) films. A gap is introduced above the dielectric so that ...
