This means that a traditional cluster such as agriculture should not be abandoned; it should be upgraded.
You might have pictured a distant galactic cluster, such as the Great Wall — perhaps 200 300 million light years away.
The country has also acquired the paraphernalia of a tech cluster, such as a celebratory blog (Arctic Startup) and a valley-related name (Arctic Valley).
In a very old cluster such as M67, which is 4.5 billion years old, all of the bright main-sequence stars have disappeared.
Designing cluster randomized trials in clinical studies often requires accurate estimates of intraclass correlation, which quantifies the strength of correlation between units, such as participants, within a cluster, such as a practice.
Using molecular dynamics computer simulation it has been shown how a large cluster such as fullerene can create an acoustic wave with sufficient energy to gently eject molecules which have been adsorbed to a surface.
In a cluster such as M3, 90 percent of the light is contained within a diameter of 100 light-years, but star counts and the study of RR Lyrae member stars (whose intrinsic brightness varies regularly within well-known limits) include a larger one of 325 light-years.
CHs are responsible for the management of the cluster such as scheduling of the medium access, dissemination of the control messages, and, the most important, data aggregation.
Of course those lucky, or strategic-minded, enough to have landed at the heart of a cluster such as Cambridge can still look further afield for advice and support.
Other methods based on cluster such as K-means have a similar problem and cost enormous computation time because of the need of calculation over the whole sample set, which makes it unrealistic for the real-time detection [30].
