Emulation and Approximation of a Flexible Delay Line by Parallel Non-Overtaking Delay Lines
—In this paper we propose to construct an flexible delay line with maximum delay d by parallel non-overtaking delay lines. We show that for a fixed number of non-overtaking del...

Approximating the top-m passages in a parallel question answering system
We examine the problem of retrieving the top-m ranked items from a large collection, randomly distributed across an n-node system. In order to retrieve the top m overall, we must ...
