    • Comparison of six almost unbiased ratio estimators 

      Dalabehera, M.; Sahoo, L.N. (Institut d'Estadística de Catalunya, 1994)
      Article
      Accés obert
      In this paper, we compare six almost unbiased ratio estimators with respect to bias and efficiency for (i) finite populations, and (ii) infinite populations in which the joint distribution of the characters under study is ...

    • Estimation of Significant Wave Height using the features of cygnss Delay Doppler Map 

      Bu, Jinwei; Hyuk, Park; Yu, Kegen; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Text en actes de congrés
      Accés obert
      Significant Wave Height (SWH) is a key parameter to characterize waves, which is typically used in sea state monitoring such as wave forecast to ensure ocean navigation safety. Satellite radar altimeter is probably the ...

    • Motion estimation using higher-order statistics 

      Sayrol Clols, Elisa; Gasull Llampallas, Antoni; Rodríguez Fonollosa, Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1996-06-30)
      Article
      Accés obert
      The objective of this paper is to introduce a fourth-order cost function of the displaced frame difference (DFD) capable of estimating motion even for small regions or blocks. Using higher than second-order statistics ...
