    • Bohr phenomena for Laplace-Beltrami operators 

      Turgay Kaptanolu H. (2006)
      We investigate a Bohr phenomenon on the spaces of solutions of weighted Laplace-Beltrami operators associated with the hyperbolic metric of the unit ball in ℂN. These solutions do not satisfy the usual maximum principle, ...
    • Expectation maximization based matching pursuit 

      Gurbuz, A.C.; Pilanci, M.; Arikan, O. (2012)
      A novel expectation maximization based matching pursuit (EMMP) algorithm is presented. The method uses the measurements as the incomplete data and obtain the complete data which corresponds to the sparse solution using an ...
    • Extraction of primary and secondary frequency control from active power generation data of power plants 

      Ozer, B.; Arikan, O.; Moral, G.; Altintas, A. (Elsevier Ltd, 2015)
      Frequency control is a vital component of a secure and robust power grid and it ought to be closely monitored. Frequency control consists of two main components; primary and secondary control and their contributions are ...
    • A recursive way for sparse reconstruction of parametric spaces 

      Teke O.; Gurbuz, A.C.; Arikan, O. (IEEE Computer Society, 2015)
      A novel recursive framework for sparse reconstruction of continuous parameter spaces is proposed by adaptive partitioning and discretization of the parameter space together with expectation maximization type iterations. ...
    • SAR image reconstruction by expectation maximization based matching pursuit 

      Ugur, S.; Arikan, O.; Gürbüz, A. C. (Academic Press, 2015)
      Synthetic Aperture Radar (SAR) provides high resolution images of terrain and target reflectivity. SAR systems are indispensable in many remote sensing applications. Phase errors due to uncompensated platform motion degrade ...
