    • Bridging the ensemble Kalman filter and particle filters: the adaptive Gaussian mixture filter 

      Stordal, Andreas Størksen; Karlsen, Hans A.; Nævdal, Geir; Skaug, Hans J.; Vallès, Brice (Springer, 2010)
      The nonlinear filtering problem occurs in many scientific areas. Sequential Monte Carlo solutions with the correct asymptotic behavior such as particle filters exist, but they are computationally too expensive when working ...

    • CCZ-equivalence of bent vectorial functions and related constructions 

      Budaghyan, Lilya; Carlet, Claude (Springer, 2011-01-06)
      We observe that the CCZ-equivalence of bent vectorial functions over F2nFn2 (n even) reduces to their EA-equivalence. Then we show that in spite of this fact, CCZ-equivalence can be used for constructing bent functions ...
