The Domatic Number of Regular Graphs
The domatic number of a graph G is the maximum number of dominating sets into which the vertex set of G can be partitioned. We show that the domatic number of a random r-regular g...

High-rate quasi-cyclic LDPC codes for magnetic recording channel with low error floor
— By implementing an FPGA-based simulator, we investigate the performance of high-rate quasi-cyclic (QC) LDPC codes for the magnetic recording channel at very low sector error ra...

Source-Based Minimum Cost Multicasting: Intermediate-Node Selection with Potentially Low Cost
Abstract. In this paper, we propose a novel heuristic algorithm for constructing a minimum cost multicast tree. Our work is based on a directed asymmetric network and shows an impr...

Dense Error Correction for Low-Rank Matrices via Principal Component Pursuit
Abstract--We consider the problem of recovering a lowrank matrix when some of its entries, whose locations are not known a priori, are corrupted by errors of arbitrarily large magn...

Optimal Column-Based Low-Rank Matrix Reconstruction
We prove that for any real-valued matrix X ∈ Rm×n , and positive integers r k, there is a subset of r columns of X such that projecting X onto their span gives a r+1 r−k+1 -a...
