CLUSTER ALGEBRAS AND CLUSTER CATEGORIES
These are notes from introductory survey lectures given at the Institute for Studies in Theoretical Physics and Mathematics (IPM), Teheran, in 2008 and 2010. We present the definition and the fundamental properties of Fomin-Zelevinsky’s cluster algebras. Then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generator...
متن کاملSatellite Cluster Command and Control
For many applications a distributed cluster of cooperating satellites offers distinct advantages over satellites functioning alone. These include optimization of mission performance and increased fault tolerance. Although there are many benefits, commanding and controlling a large cluster of cooperating satellites poses several challenges. These include how satellites in the cluster maintain kn...
متن کاملCoordinated Control of Tethered Satellite Cluster Systems
We propose the concept of Tethered Satellite Cluster Systems, which keep and change the constellation with the tension/length control of tethers. The purpose of the system is the formation flight to perform the observation, communication and rendezvous-docking missions. The system is applied to tethered service satellites, which perform the missions, for example an automatic casting, capture, r...
متن کاملCluster Command & Control (C3) Tools Suite
The computation power of PC clusters running the Linux operating system rivals that of supercomputers of just a few years ago at a fraction of the purchase price. However, the lack of good administration and application tools represents a hidden operation cost that is often overlooked when proposing a cluster. This paper presents a number of command line tools developed at Oak Ridge National La...
متن کاملCluster Analysis for Multivariable Process Control
be profitable to industry in the long term, but also creates an academic interest in the field of multivariable control. a search window is placed, whose lower and upper limits [lower, upper] are [C(x j)-a(x j) , C(x j) + a(x j)] for j = 1 ... N (1) where C(x j) is the centre of the search window on the x j axis a(x j) is the predefined length interval on the x j axis. The centre of gravity (c....
