Dynamic Real-Time Optimistic Concurrency Control
In a recent study, we have shown that in real-time database systems that discard late transactions, optimistic concurrency control outperforms locking. Although the optimistic alg...

Integrating Semi-Join-Reducers into State of the Art Query Processors
Semi-join reducers were introduced in the late seventies as a means to reduce the communication costs of distributed database systems. Subsequent work in the eighties showed, howe...

Algebraic Techniques for Timed Systems
Performance evaluation is a central issue in the design of complex real-time systems. In this work, we propose an extension of socalled "Max-Plus" algebraic techniques to...

Whole-History Rating: A Bayesian Rating System for Players of Time-Varying Strength
Whole-History Rating (WHR) is a new method to estimate the time-varying strengths of players involved in paired comparisons. Like many variations of the Elo rating system, the whol...

Decentralized Schemes for Size Estimation in Large and Dynamic Groups
Large-scale and dynamically changing distributed systems such as the Grid, peer-to-peer overlays, etc., need to collect several kinds of global statistics in a decentralized manne...
