Abstract. In this paper, we present self-avoiding walks as a novel technique to linearize" a triangular mesh. Unlike space- lling curves which are based on a geometric embeddi...
This paper proposes a prefix-tree structure, called CPS-tree (Compact Pattern Stream tree) that efficiently discovers the exact set of recent frequent patterns from high-speed dat...
We present iClusterDL, a self-organising overlay network that supports information retrieval and filtering functionality in a digital library environment. iClusterDL is able to han...
