Clustering technique for conceptual clusters [PDF]

open access: yesProceedings of the 11th edition of the International Workshop on Smalltalk Technologies, 2016
Clustering aims to classify elements into groups called classes or clusters. Clustering is used in reverse-engineering to help to understand legacy software. It is also a tech-nic used in re-engineering to propose gatherings of software entities to engineers who can then accept them or not. This paper presents a Pharo implementation of an iterative and

Intra-cluster Globular Clusters in a Simulated Galaxy Cluster [PDF]

open access: yesThe Astrophysical Journal, 2018
Abstract Using a cosmological dark matter simulation of a galaxy-cluster halo, we follow the temporal evolution of its globular cluster population. To mimic the red and blue globular cluster populations, we select at high redshift two sets of particles from individual ...

Emergence Patterns of Rare Arable Plants and Conservation Implications

open access: yesPlants, 2020
Knowledge on the emergence patterns of rare arable plants (RAP) is essential to design their conservation in Europe. This study hypothesizes that is possible to find functional groups with similar emergence patterns within RAP with the aim of ...

Cluster lenses [PDF]

open access: yesThe Astronomy and Astrophysics Review, 2011
Clusters of galaxies are the most recently assembled, massive, bound structures in the Universe. As predicted by General Relativity, given their masses, clusters strongly deform space-time in their vicinity. Clusters act as some of the most powerful gravitational lenses in the Universe.
