Interactive image segmentation via minimization of quadratic energies on directed graphs
We propose a scheme to introduce directionality in the Random Walker algorithm for image segmentation. In particular, we extend the optimization framework of this algorithm to com...

Non-uniform clock mesh optimization with linear programming buffer insertion
Clock meshes are extremely effective at filtering clock skew from environmental and process variations. For this reason, clock meshes are used in most high performance designs. Ho...

Sum Capacity of One-Sided Parallel Gaussian Interference Channels
Abstract--The sum capacity of the one-sided parallel Gaussian interference channel is shown to be a concave function of user powers. Exploiting the inherent structure of the proble...

Coordinated beamforming with limited feedback in the MIMO broadcast channel
In this paper, we propose a new joint optimization of linear transmit beamforming and receive combining vectors for the multiple-input multiple-output (MIMO) broadcast channel. We ...

Multiplicative Nonnegative Graph Embedding
In this paper, we study the problem of nonnegative graph embedding, originally investigated in [14] for reaping the benefits from both nonnegative data factorization and the spe...
