Star formation efficiency in galaxy clusters
(EDP SCIENCES S A, 2008)
Context. The luminous material in clusters of galaxies exists in two forms: the visible galaxies and the X-ray emitting intra-cluster medium. The hot intra-cluster gas is the major observed baryonic component of clusters, ...
EVOLUTION OF ADENINE CLUSTERING IN 5S RIBOSOMAL-RNA
(Tubingen Univ Press Attempto Verlag, 1992-12-01)
The frequency of adenine mononucleotides (A), dinucleotides (AA) and clusters, and the positions of clusters, were studied in 502 molecules of the 5S rRNA.All frequencies were reduced in the evolutive lines of vertebrates, ...
Barriers to environmental management in clusters of small businesses in Brazil and Japan: from a lack of knowledge to a decline in traditional knowledge
(Taylor & Francis Inc, 2012-06-01)
This study aimed to examine the main barriers to environmental management (EM) in two clusters of small businesses (SBs). A study of two clusters was performed: one cluster in Brazil (the leather/shoe sector) and one cluster ...
A divisive clustering method for functional data with special consideration of outliers
(Springer, 2017-08)
This paper presents DivClusFD, a new divisive hierarchical method for the non-supervised classification of functional data. Data of this type present the peculiarity that the differences among clusters may be caused by ...
Diagnostic tool to analyse colour-magnitude diagrams of poorly populated stellar concentrations
(WILEY-BLACKWELL, 2011)
The dynamical processes that lead to open cluster disruption cause its mass to decrease. To investigate such processes from the observational point of view, it is important to identify open cluster remnants (OCRs), which ...
Luminosity and mass functions of galactic open clusters, II: NGC 4852
(EDP Sciences, 2005-06)
We present wide-field deep UBVI photometry for the previously unstudied open cluster NGC 4852 down to a limiting magnitude I ∼ 24, obtained from observations taken with the Wide Field Imager camera on-board the MPG/ESO 2.2 ...
Evolving clusters in gene-expression data
(Elsevier Science IncNew YorkEUA, 2006)
Evolutionary fuzzy clustering of relational data
(ELSEVIER SCIENCE BV, 2011)
This paper is concerned with the computational efficiency of fuzzy clustering algorithms when the data set to be clustered is described by a proximity matrix only (relational data) and the number of clusters must be ...
Innovation in industrial clusters: A survey of footwear companies in Brazil
(2013-10-25)
The aim of this study is to characterize the relationships in innovation and business clustering processes in the productive chain of small and medium enterprises (SME) of Brazil. The object of study are SMEs the local ...
