We reduce the approximation factor for Vertex Cover to 2 − Θ( 1√ log n ) (instead of the previous 2 − Θ(log log n log n ), obtained by Bar-Yehuda and Even [2], and by Moni...
Abstract. We investigate a general paradigm for constructing arbitraryinput-length (AIL) MACs from fixed-input-length (FIL) MACs, define the waste as the relevant efficiency para...
The tier aspect model addresses Aspect Oriented Programming (AOP) in the context of database applications. It is a new technique of separation of concerns through tiers implemented...
Wireless network research still lacks methods to integratively evaluate the performance that can be expected from application layer protocols. The user behavior is predominantly a...
