We aim at characterizing graphical models for convolution splitting distributions. Only marginal independence have been studied through the well-known Rao–Rubin condition. We generalize this condition for conditional independence and deduce the desired characterizations.
In functional-structural plant models, inferring latent levels of organization from data while accounting for both connections between levels and within-individual heterogeneity is a challenging task. Here, we develop an approach based on multiple change-point models. It aims at partitioning a heterogeneous tree into homogeneous subtrees of consequent sizes. While multiple change-point models for...
. Aladin, the CDS interactive sky atlas is one of the important interoperability tools of the astronomy Web. Several recent improvements prepare it for use as a portal to the Phase A of the Astrophysical Virtual Observatory (AVO), as shown by its use as a testbed for the AVO-January 2003 demonstration (Quinn, P., 2002).
. The VOTable format is now an agreed upon XML standard for representing tabular data in the VO context. Tabular data are an important part of the data exchanged between all participants in the Virtual Observatory: such representations include data extracted from catalogues and surveys, calibration parameters and data, results of modelling applications, etc. An accurate description of what these data...
. The Image archive model described here has been developed within the scope of the IDHA (Images Distribuées Hétérogènes pour l’Astronomie) project. The IDHA project led by CDS, associates image processing scientists of LSIIT (Strasbourg), and astronomers of several French Institutes including TERAPIX from IAP, and Queen’s University (Belfast). IDHA goal is to describe the information content of image...
