A Cluster Analysis Method for Grouping Means in the Analysis of Variance
, 1974It is sometimes useful in an analysis of variance to split the treatments into reasonably homogeneous groups. Multiple comparison procedures are often used for this purpose, but a more direct method is to use the techniques of cluster analysis.

In this chapter, we shall show several spatial point patterns in a hypothetical area of a square 10 km on each side to understand what “clustering” or “a cluster” means and to get a basic idea of how to approach detection of clustering or clusters.

Clusters and Cluster Reactions
1996Atomic clusters [1,2] constitute a new class of matter intermediate between atoms/molecules and solids. Clusters of any elements can be produced by initially vaporizing [3] the target through an intense laser and allowing the plume to cool in a supersonic expansion chamber.

Intrinsic anisotropy of clusters in cluster-cluster aggregation
Journal of Physics A: Mathematical and General, 1986The anisotropy ratio between the largest and the smallest eigenvalues of the radius of gyration tensor Rij2 has been analytically investigated and numerically estimated for three different cluster-cluster aggregation processes. This ratio is of the order of 4.5 for a two-dimensional projection of a three-dimensional cluster grown by cluster-cluster ...

To Cluster or Not to Cluster: A Hybrid Clustering Protocol for WSN
2019 IEEE Jordan International Joint Conference on Electrical Engineering and Information Technology (JEEIT), 2019Clustering protocols in wireless sensors networks (WSN) have dominated as a tailored routing protocols to harvest and route data from sensorsS nodes to the sink station. A lot of clustering protocols have been proposed in the literature. However, does clustering algorithms work correctly in all cases? In other words, is it necessary for the nodes to be

Cluster headache and cluster variants
Current Treatment Options in Neurology, 2003Patients must be cognizant of the time course of the cluster headache periods to optimally tailor their therapy. Steroids provide the fastest onset of prophylactic effect. Once steroids are initiated, it remains difficult to wean patients off of them, and that is why it is always recommended to associate another prophylactic agent from the onset with ...

Dynamic cluster-size distribution in cluster-cluster aggregation: Effects of cluster diffusivity
Physical Review B, 1985The dynamics of the diffusion-limited model of cluster-cluster aggregation is investigated in two and three dimensions by studying the temporal evolution of the cluster-size distribution ${n}_{s}$(t), which is the number of clusters of size s at time t.

THE APPLICATION OF CLUSTER ANALYSIS IN STRATEGIC MANAGEMENT RESEARCH: AN ANALYSIS AND CRITIQUE
, 1996Cluster analysis is a statistical technique that sorts observations into similar sets or groups. The use of cluster analysis presents a complex challenge because it requires several methodological choices that determine the quality of a cluster solution.
