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 ...
Factors that cause genotype by environment interaction and use of a multiple-trait herd-cluster model for milk yield of Holstein cattle from Brazil and Colombia
(2004-08-01)
Descriptive herd variables (DVHE) were used to explain genotype by environment interactions (G x E) for milk yield (MY) in Brazilian and Colombian production environments and to develop a herd-cluster model to estimate ...

First CCD UBVI photometric analysis of four moderately young open clusters in the third galactic quadrant
(Wiley Blackwell Publishing, Inc, 2010-10)
We present CCD photometry in the Johnson UBV and Kron-Cousins I systems down to V~ 22.0 for the open clusters NGC 2311, Trumpler 6, NGC 2432 and BH 54 and their surrounding fields. Trumpler 6 and BH 54 have never been ...
New aspects of the elastic net algorithm for cluster analysis
(SPRINGER LONDON LTD, 2011)
ASteCA: Automated Stellar Cluster Analysis
(Edp Sciences, 2015)
We present the Automated Stellar Cluster Analysis package (ASteCA), a suit of tools designed to fully automate the standard tests applied on stellar clusters to determine their basic parameters. The set of functions included ...
An algorithm based on density and compactness for dynamic overlapping clustering
(Elsevier Ltd., 2013)
Analysis of genetic association using hierarchical clustering and cluster validation indices
(Academic Press Inc Elsevier Science, 2017-10)
It is usually assumed that co-expressed genes suggest co-regulation in the underlying regulatory network. Determining sets of co-expressed genes is an important task, based on some criteria of similarity. This task is ...
On the role of PES data in the identification of metal-metal charge transfer bands in clusters of clusters
(Elsevier Science Publ. B.V., 1993)
The clusters of M2[O2CCCo3(CO)9]4-n[O2CR]n, where M is Cr, n= O; where M is Mo, n = 0,1, R is CH3; where M is W, n=0; exhibit allowed transitions with absorvance maxima that correlate with the lowest ionization energy of ...
Validation of a pre-clustering strategy for a recommender system
(Florianópolis, SC, 2019-12-06)
In this work we used a proof of concept to validate a pre-clustering strategy using firmographics data in order to improve the performance of Neoway's recommender system. The context of recommender systems is discussed, ...
