On the Complexity of Coordination [PDF]

Mathematics of Operations Research, 2003
Many results on repeated games played by finite automata rely on the complexity of the exact implementation of a coordinated play of length n. For a large proportion of sequences, this complexity appears to be no less than n. We study the complexity of a coordinated play when allowing for a few mismatches.

Suppression of Dissolution Rate via Coordination Complex in Tungsten Chemical Mechanical Planarization

Applied Sciences, 2022
Topography of tungsten should be assured at a minimum through chemical mechanical planarization (CMP) in the metal gate structures (e.g., buried gates, replacement metal gates) and via contact in the middle of line (MOL) process for sub−7 nm ...

Coordination Control of Complex Machines [PDF]

, 2014
Control and coordination are important aspects of the development of complex machines due to an ever-increasing demand for better functionality, quality, and performance. In WP6 of the C4C project, we developed a synthesis-centric systems engineering framework suitable for supervisory coordination of complex systems.
