Eigenvalue estimates on bakry–Émery manifolds
(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
(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
(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 ...
