Abstract. We develop a simple combinatorial algorithm for computing the smallest enclosing ball of a set of points in high dimensional Euclidean space. The resulting code is in mos...
In this paper we present HOPI, a new connection index for XML documents based on the concept of the 2?hop cover of a directed graph introduced by Cohen et al. In contrast to most o...
Web cache technologies have been developed as an extension of CPU cache, by modifying LRU (Least Recently Used) algorithms. Actually in web cache systems, we can use disks and ter...
In order to navigate huge document collections efficiently, tagged hierarchical structures can be used. For users, it is important to correctly interpret tag combinations. In this ...
Anomaly detection in IP networks, detection of deviations from what is considered normal, is an important complement to misuse detection based on known attack descriptions. Perfor...
