    • A parametric-space-based scan-line algorithm for rendering of bicubic surfaces 

      Pueyo Sánchez, Xavier; Brunet Crosa, Pere (1987)
      Article
      Accés obert
      A novel scan-line algorithm for displaying bicubic surfaces is presented. Patches are decomposed on regions of constant sign of the z component of the normal before the scan process. Most of the computations are done in ...

    • An alternative procedure to obtain the mortality rate with non-linear functions: Application to the case of the Spanish population 

      Postigo Boix, Marcos; Agüero Calvo, Ramón; Melus Moreno, José Luis (Public Library of Science (PLOS), 2019-10-15)
      Article
      Accés obert
      This paper presents an alternative calculation procedure to calculate the mortality rate, exploiting the data available in the Eurostat demography database for Spain. This methodology has been devised based on two of the ...

    • Fitting a two-joint orthogonal chain to a point set 

      Díaz-Báñez, José Miguel; López, Mario A.; Mora Giné, Mercè; Seara Ojea, Carlos; Ventura, Inmaculada (2011-04)
      Article
      Accés obert
      We study the problem of fitting a two-joint orthogonal polygonal chain to a set S of n points in the plane, where the objective function is to minimize the maximum orthogonal distance from S to the chain. We show that this ...

    • Spectral processing techniques for efficient monitoring in optical networks 

      Locatelli, Fabiano; Christodoulopoulos, Konstantinos; Svaluto Moreolo, Michela; Fàbrega Sánchez, Josep Maria; Nadal Reixats, Laia; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2021-07-01)
      Article
      Accés obert
      Having ubiquitous optical monitors in dense wavelength-division multiplexing (DWDM) or flex-grid networks allows the estimation in real time of crucial parameters. Such monitoring would be even more important in disaggregated ...
