We extend Ukkonen's online suffix tree construction algorithm to support frequency queries, by adding count fields to the internal nodes of the tree, as suggested in [8]. Thi...
We consider the routing for a special type of communication requests, called a multicast, consisting of a fixed source and a multiset of destinations in a wavelength division mult...
Regular tree queries (RTQs) are a class of queries considered especially relevant for the expressiveness and evaluation of XML query languages. The algorithms proposed so far for ...
This paper presents an approach to generate audio based learning material dynamically from Wikipedia articles for m-Learning and ubiquitous access. It introduces the so called ’...
We address the problem of online route discovery for a class of graphs that can be embedded either in two or in three dimensional space. In two dimensions we propose the class of ...
