      Eigenvalue estimates on bakry–Émery manifolds 

      Charalambous, N.; Lu, Z.; Rowlett, J. (Springer Verlag, 2015)
      We demonstrate lower bounds for the eigenvalues of compact Bakry– Émery manifolds with and without boundary. The lower bounds for the first eigenvalue rely on a generalized maximum principle which allows gradient estimates ...

      Minimizing outage probability for a class of MIMO channels 

      Charalambous, Charalambos D.; Ioannou, I. (2009)
      In this paper we investigate the outage probability of Multiple-Input Multiple-Output (MIMO) channels, when the probability distribution of the channel gains is not completely known to the transmitter and receiver. The ...

      Non-stationary texture segmentation using an AM-FM model 

      Pattichis, Marios S.; Christodoulou, Christodoulos I.; Pattichis, Constantinos S.; Bovik, Alan Conrad (1997)
      We present a novel method for segmenting non-stationary textures. Our approach uses a multidimensional AM-FM representation for the texture, and provides the FM features to an SOFM-LVQ neural network system that performs ...
