    • d-Choquet integrals: Choquet integrals based on dissimilarities 

      Bustince Sola, Humberto Upna; Mesiar, Radko; Fernández Fernández, Francisco Javier Upna; Galar Idoate, Mikel Upna; Paternain Dallo, Daniel Upna; Altalhi, A. H.; Pereira Dimuro, Graçaliz Upna; Bedregal, Benjamin Upna; Takáč, Zdenko (Elsevier, 2020)   Artículo / Artikulua
      The paper introduces a new class of functions from [0,1]n to [0,n] called d-Choquet integrals. These functions are a generalization of the 'standard' Choquet integral obtained by replacing the difference in the definition ...

    • Efficient SSP low-storage Runge-Kutta methods 

      Roldán Marrodán, Teodoro Upna; Higueras Sanz, Inmaculada Upna (2019)   Artículo / Artikulua  OpenAccess
      In this paper we study the efficiency of Strong Stability Preserving (SSP) Runge-Kutta methods that can be implemented with a low number of registers using their Shu-Osher representation. SSP methods have been studied ...

    • Fair competition design 

      Arlegi Pérez, Ricardo Upna; Dimitrov, Dinko (2018)   Documento de trabajo / Lan gaiak  OpenAccess
      We study the impact of two basic principles of fairness on the structure of competition systems and perform our analysis by focusing on sports competitions. The first principle states that equally strong players should ...

    • Local properties of strengthened ordered directional and other forms of monotonicity 

      Sesma Sara, Mikel Upna; Miguel Turullols, Laura de Upna; Mesiar, Radko; Fernández Fernández, Francisco Javier Upna; Bustince Sola, Humberto Upna (Springer, 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this study we discuss some of the recent generalized forms of monotonicity, introduced in the attempt of relaxing the monotonicity condition of aggregation functions. Specifically, we deal with weak, directional, ordered ...

    • Mixture functions and their monotonicity 

      Špirková, Jana; Beliakov, Gleb Upna; Bustince Sola, Humberto Upna; Fernández Fernández, Francisco Javier Upna (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      We consider mixture functions, which are a type of weighted averages for which the corresponding weights are calculated by means of appropriate continuous functions of their inputs. In general, these mixture function need ...

    • Optimal monotonicity-preserving perturbations of a given Runge–Kutta method 

      Higueras Sanz, Inmaculada Upna; Ketcheson, David I.; Kocsis, Tihamér A. (Springer, 2018)   Artículo / Artikulua  OpenAccess
      Perturbed Runge–Kutta methods (also referred to as downwind Runge–Kutta methods) can guarantee monotonicity preservation under larger step sizes relative to their traditional Runge–Kutta counterparts. In this paper we study ...

    • Strong stability preserving properties of composition Runge-Kutta schemes 

      Higueras Sanz, Inmaculada Upna; Roldán Marrodán, Teodoro Upna (Springer, 2019)   Artículo / Artikulua  OpenAccess
      In this paper Strong Stability Preserving (SSP) properties of Runge Kutta methods obtained by com- posing k different schemes with different step sizes are studied. The SSP coefficient of the composition method is obtained ...
