    Extracting the light trapped in a waveguide, or the opposite effect of trapping light in a thin region and guiding it perpendicular to its incident propagation direction, is essential for optimal energetic performance in ...
  • Analysis and synthesis of textures through the inference of Boolean functions 

    Domínguez Pumar, Manuel; Torres Urgell, Lluís (1997-05)
    Article
    Accés restringit per política de l'editorial
    This work deals with Boolean functions of non-linear and linear basis. The Boolean random functions of non-linear basis were proposed by Serra (1988,1989). These functions are generated through a Poisson point process upon ...
