Open clusters: III. Fundamental parameters of B stars in NGC 6087, NGC 6250, NGC 6383 and NGC 6530. B type stars with circumstellar envelopes.
(EDP Sciences, 2018-02)
Context. Stellar physical properties of star clusters are poorly known and the cluster parameters are often quite uncertain.Aims. Our goals are to perform a spectrophotometric study of the B star population in open clusters ...
An efficient Particle Swarm Optimization approach to cluster short texts
(Elsevier, 2014-05)
Short texts such as evaluations of commercial products, news, FAQ’s and scientific abstracts are important resources on the Web due to the constant requirements of people to use this on line information in real life. In ...
The Mass of the Most Massive Star in Stellar Clusters Determined from 25 Million MASSCLEAN Monte Carlo Simulations
(2013)
Is there a maximum universal stellar mass, or might the maximum stellar mass in a cluster be tied to the mass of the associated cluster? Direct measurements of the maximum stellar mass of hundreds of young stellar clusters ...
Análisis de rendimiento de un clúster HPC y, arquitecturas manycore y multicorer
(2017)
Currently the tendency to obtain a large amount of computing, is through parallel computing, a clear example lies in the fact that the fastest computers in the world are clusters for high performance computing, formed by ...
Clustering using PK-D: A connectivity and density dissimilarity
(Pergamon-Elsevier Science Ltd, 2016-06)
We present a new dissimilarity, which combines connectivity and density information. Usually, connectivity and density are conceived as mutually exclusive concepts; however, we discuss a novel procedure to merge both ...
Fuzzy C-Means Clustering with Histogram based Cluster Selection for Skin Lesion Segmentation using Non-Dermoscopic Images
Purpose – Pre-screening of skin lesion for malignancy is highly demanded as melanoma being a life-threatening skin cancer due to unpaired DNA damage. In this paper, lesion segmentation based on Fuzzy C-Means clustering ...
An Alternative View of the Convergence Issue of Growth Empirics
(Wiley, 2011-09)
In this paper we study the dynamics of economic growth for 140 countries during the period 1951-2003. The variables representing economic performance are levels and growth rates of per capita GDP. Using the concept of ...
