    • Unbalanced interval-valued OWA operators 

      Miguel Turullols, Laura de Upna; Bustince Sola, Humberto Upna; Barrenechea Tartas, Edurne Upna; Pagola Barrio, Miguel Upna; Fernández Fernández, Francisco Javier Upna (Springer Berlin Heidelberg, 2016)   Artículo / Artikulua  OpenAccess
      In this work, we introduce a new class of functions defned on the interval-valued setting. These functions extend classical OWA operators but allow for diferent weighting vectors to handle the lower bounds and the ...
    • Wideband backscattering reduction at terahertz using compound reflection grating 

      Orazbayev, Bakhtiyar Upna; Rodríguez Ulibarri, Pablo Upna; Beruete Díaz, Miguel Upna (Optical Society of America, 2017)   Artículo / Artikulua  OpenAccess
      Backscattering reduction is usually achieved by using either absorbers or diffractions gratings at the expense of a narrow bandwidth. In this paper, we propose a different strategy based on a metallic compound reflection ...
