    • Growth in the number of references in engineering journal papers during the 1972-2013 period 

      Úcar Marqués, Iñaki; López Fernandino, Felipe; Rodríguez Ulibarri, Pablo Upna; Sesma Sánchez, Laura Upna; Urrea Micó, Verónica; Sevilla Moróder, Joaquín Upna (Springer, 2014)   Artículo / Artikulua  OpenAccess
      The number of references per paper, perhaps the best single index of a journal’s scholarliness, has been studied in different disciplines and periods. In this paper we present a four decade study of eight engineering ...
    • Polarization diversity scheme for BOTDA sensors based on a double orthogonal pump interaction 

      Urricelqui Polvorinos, Javier Upna; López Fernandino, Felipe; Sagüés García, Mikel Upna; Loayssa Lara, Alayn Upna (IEEE, 2015)   Artículo / Artikulua  OpenAccess
      We introduce a Brillouin optical time domain analysis (BOTDA) sensor deploying a novel polarization diversity technique based on the use of two orthogonal pump pulses which simultaneously interact with a phase modulated ...
