An Experimental Study on Microarray Expression Data from Plants under Salt Stress by using Clustering Methods
Current Genome-wide advancements in Gene chips technology provide in the “Omics (genomics, proteomics and transcriptomics) research”, an opportunity to analyze the expression levels of thousand of genes across multiple ...
Hybrid evolutionary algorithm for the Capacitated Centered Clustering Problem
(Pergamon-Elsevier B.V. Ltd, 2011-05-01)
The Capacitated Centered Clustering Problem (CCCP) consists of defining a set of p groups with minimum dissimilarity on a network with n points. Demand values are associated with each point and each group has a demand ...

The HST/ACS Coma Cluster Survey. IV. Intergalactic Globular Clusters and the Massive Globular Cluster System at the Core of the Coma Galaxy Cluster
(2011)
Intracluster stellar populations are a natural result of tidal interactions in galaxy clusters. Measuring these populations is difficult, but important for understanding the assembly of the most massive galaxies. The Coma ...
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 ...
Open clusters in the third galactic quadrant - II. The intermediate age open clusters NGC 2425 and NGC 2635
(EDP SCIENCES, 2006-01)
We analyse CCD broad band (UBV(RI)(C)) photometric data obtained in the fields of the poorly studied open clusters NGC 2425 and NGC 2635. Both clusters are found to be of intermediate age thus increasing the population of ...
