Redundancy Elimination on RDF Graphs in the Presence of Rules, Constraints, and Queries
Based on practical observations on rule-based inference on RDF data, we study the problem of redundancy elimination on RDF graphs in the presence of rules (in the form of Datalog r...

Soft-input soft-output single tree-search sphere decoding
Soft-input soft-output (SISO) detection algorithms form the basis for iterative decoding. The computational complexity of SISO detection often poses significant challenges for prac...

Efficient lattice-reduction-aided MMSE decision-feedback equalization
Since optimum diversity behavior can be achieved, equalization based on lattice basis reduction is of special interest for transmission over MIMO channels. Although the per-symbol...

Scheduling Multiple Divisible Loads
In this paper we study the scheduling of multiple divisible loads on a star network of processors. We show that this problem is computationally hard. Special cases solvable in pol...
