QK-Means: A clustering technique based on community detection and K-Means for deployment of cluster head nodes
Wireless Sensor Networks (WSN) are a special kind of ad-hoc networks that is usually deployed in a monitoring field in order to detect some physical phenomenon. Due to the low dependability of individual nodes, small radio ...
Structure and kinetics of formation of APTS/GPTS-derived organic/inorganic hybrids
The structure and the kinetics of formation of APTS/GPTS-derived organic/inorganic hybrids were studied in situ by small-angle-X-ray scattering. The data were interpreted in terms of a process of primary particles formation ...
ASAClu: selecionando clusters diversos e relevantes
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Ciência da Computação (Campus SOROCABA)Câmpus Sorocaba, 2016-12-12)
No clustering algorithm is guaranteed to find actual groups in any dataset. To deal with this problem, many techniques apply various clustering algorithms to a dataset, generating a set of partitions and assessing them to ...
A new index for clustering validation with overlapped clusters
(Pergamon-Elsevier Science Ltd, 2016-08)
External validation indexes allow similarities between two clustering solutions to be quantified. With classical external indexes, it is possible to quantify how similar two disjoint clustering solutions are, where each ...
New measurements of radial velocities in clusters of galaxies-V
(EDP SCIENCES S A, 2010)
As a part of our galaxy-cluster redshift survey, we present a set of 79 new velocities in the 4 clusters Abell 376, Abell 970, Abell 1356, and Abell 2244, obtained at Haute-Provence observatory. This set now completes our ...
