Grammar-based genetic programming for timetabling
Abstract— We present a grammar-based genetic programming framework for the solving the timetabling problem via the evolution of constructive heuristics. The grammar used for prod...

A Geometric Consequence of Residual Smallness
We describe a new way to construct large subdirectly irreducibles within an equational class of algebras. We use this construction to show that there are forbidden geometries of m...

MIMO UWB Systems Based on Linear Precoded OFDM for Home Gigabit Applications
Abstract— In this paper, we investigate the use of multipleinput multiple-output (MIMO) techniques with linear precoded orthogonal frequency division multiplexing (LP-OFDM) wavef...
