Many sensor network applications, such as object tracking and disaster monitoring, require effective techniques for event detection. In this paper, we propose a novel event detect...
With the total energy consumption of computing systems increasing in a steep rate, much attention has been paid to the design of energy-efficient computing systems and applications...
An important class of queries is the LIKE predicate in SQL. In the absence of an index, LIKE queries are subject to performance degradation. The notion of indexing on substrings (...
