Kinematic parameters and membership probabilities of open clusters in the Bordeaux PM2000 catalogue
(EDP SCIENCES S A, 2010)
Aims. We derive lists of proper-motions and kinematic membership probabilities for 49 open clusters and possible open clusters in the zone of the Bordeaux PM2000 proper motion catalogue (+ 11 degrees <= delta <= + 18 ...
Intra-cluster globular clusters around NGC 1399 in Fornax?
(EDP Sciences, 2008-01)
We investigate whether the globular clusters (GCs) in the recently published sample of GCs in the Fornax cluster by Bergond and coworkers are indeed intra-cluster objects. Methods. We combine their catalogue of radial ...
Spiral-like structure at the centre of nearby clusters of galaxies
(EDP SCIENCES S A, 2010)
Context. X-ray data analysis have found that fairly complex structures at cluster centres are more common than expected. Many of these structures have similar morphologies, which exhibit spiral-like substructure. Aims. It ...
Novel Clustering Method Based on K-Medoids and Mobility Metric
The structure and constraint of MANETS influence negatively the performance of QoS, moreover the main routing protocols proposed generally operate in flat routing. Hence, this structure gives the bad results of QoS when ...
Improving hierarchical document cluster labels through candidate term selection
(2012-09-03)
One way to organize knowledge and make its search and retrieval easier is to create a structural representation divided by hierarchically related topics. Once this structure is built, it is necessary to find labels for ...
Big bang methodology applied to atomic clusters
(2011)
An implementation of a novel strategy for cluster geometry optimization, using a stochastic method, is applied. This algorithm is based on the spirit of Big Bang theory. The strategy consists on a three-step procedure; a ...
Citizen criminality assessment in lima city using the grey clustering method
(Institute of Electrical and Electronics Engineers Inc., 2017-08)
Citizen criminality has become an important social problem in Lima city, due to the fact that the number of crimes has increased. In this study, we conducted a citizen criminality assessment using the grey clustering method, ...
Multispectral images segmentation using new fuzzy cluster centroid modified
(Institute of Electrical and Electronics Engineers Inc., 2017)
The presence of outliers, noise, corrupt pieces of data and great quantity of samples in a multispectral image, makes the segmentation analysis work tedious. The fuzzy clustering approach, specially, is susceptible to ...
