We consider the problem of identifying periodic trends in data streams. We say a signal a ∈ Rn is p-periodic if ai = ai+p for all i ∈ [n − p]. Recently, Erg¨un et al. [4] pr...
We consider a fundamental flow maximization problem that arises during the evaluation of multiple overlapping queries defined on a data stream, in a heterogenous parallel environm...
raction that a programming language provides influences the structure and algorithmic complexity of the resulting programs: just imagine creating an artificial intelligence engine ...
with this, the thread abstraction was introduced. While threads are handling events, or awaiting specific events, unrelated events can be handled by other threads. Unfortunately, ...
During the past ve years scientists discovered that modern UNIX workstations connected with ethernet and ber networks could provide enough computational performance to compete wit...
