      The standard forward kinematics analysis of 3-RPR planar parallel platforms boils down to computing the roots of a sextic polynomial. There are many different ways to obtain this polynomial but all of them include exceptions ...

      This paper proposes a nonlinear, output feedback, adaptive controller to increase the stability margin of a direct-current (DC), small-scale, electrical network containing an unknown constant power load. Due to their ...
    • Subset selection for multi-Gabor and non-orthogonal wavelets expansions 

      Rebollo-Neira, L; Fernández Rubio, Juan Antonio; Janer, L (IEEE Signal Processing Society, 1998)

      Accés obert
      Non-orthogonal wavelets and Gabor or multi-windows Gabor expansions involving well-localized synthesis/analysis functions are characterized by being redundant. This entails that the signal modeling is carried out through ...
