Abstract. We give an affirmative answer to Brendle’s and Hruˇs´ak’s question of whether the club principle together with h > ℵ1 is consistent. We work with a class of ax...
Data mining algorithms use various Trie and bitmap-based representations to optimize the support (i.e., frequency) counting performance. In this paper, we compare the memory requi...
Temporal Constraint Satisfaction Problems (TCSP) is a well known approach for representing and processing temporal knowledge. Important properties of the knowledge can be inferred...
In this paper, we propose a novel Geographic Multicast routing Protocol (GMP) for wireless sensor networks1 . The proposed protocol is fully distributed and stateless. Given a set...
Answering aggregate queries like sum, count, min, max over regions containing moving objects is often needed for virtual world applications, real-time monitoring systems, etc. Sin...
