Pattern discovery plays an important part in the graph analysis process. Good examples are the detection of communities in social networks or the clustering into pathways of metabolic networks. ...
However, elements may be shared by several clusters, making the patterns entangled. When mining such data, experts are usually interested in both each individual cluster and their overlaps. ...
The first one consists in clicking on an element of the network and then displaying only the hulls associated to the clusters the element belongs to. ...

The straight polygon divides the space into polygons recursively and each polygon can be viewed as grouping of a subset of the dots. The number of polygons generated is O(n). ...
It then applies the straight polygon transformation to an initial polygon derived from the spanning tree. ...

The classical trajectories of single particle motion in a Wodds-Saxon and a modified Nilsson potential are studied for axial quadrupole deformation. ...
Both cases give rise to chaotic behaviour when the deformation in the Woods-Saxon and the l**2 term in the modified Nilsson potential are turned on. ...
For the Hamilton function of Eq.( 1 ) an appropriate choice of p θ can likewise lead to polygon orbits such as a triangle, square, pentagon, but also a five star, and so forth. ...

A small bandwidth leads to overfitting, and the resulting SVDD classifier overestimates the number of anomalies. ...

Our main contributions include a clustering algorithm tailored towards forming logical groups while respecting roads, a polyline simplification algorithm that maintains boundary facades, and a LOD process ...
Instead of the traditional vertex/polygon/edge decimation or merging, we aggregate meshes into "logical" clusters and simplify and texture each cluster separately. ...
