Hierarchy construction schemes within the Scale set framework
Segmentation algorithms based on an energy minimisation framework often
depend on a scale parameter which balances a fit to data and a regularising
term. Irregular pyramids are defined as a stack of graphs successively reduced.
Within this framework, the scale is often defined implicitly as the height in
the pyramid. However, each level of an irregular pyramid can not usually be
readily associated to the global optimum of an energy or a global criterion on
the base level graph. This last drawback is addressed by the scale set
framework designed by Guigues. The methods designed by this author allow to
build a hierarchy and to design cuts within this hierarchy which globally
minimise an energy. This paper studies the influence of the construction scheme
of the initial hierarchy on the resulting optimal cuts. We propose one
sequential and one parallel method with two variations within both. Our
sequential methods provide partitions near the global optima while parallel
methods require less execution times than the sequential method of Guigues even
on sequential machines

Refurbishing Voyager 1 & 2 Planetary Radio Astronomy (PRA) Data
Voyager/PRA (Planetary Radio Astronomy) data from digitized tapes archived at
CNES have been reprocessed and recalibrated. The data cover the Jupiter and
Saturn flybys of both Voyager probes. We have also reconstructed
goniopolarimetric datasets (flux and polarization) at full resolution. These
datasets are currently not available to the scientific community, but they are
of primary interest for the analysis of the Cassini data at Saturn, and the
Juno data at Jupiter, as well as for the preparation of the JUICE mission. We
present the first results derived from the re-analysis of this dataset.Comment: Accepted manuscript for PRE8 (Planetary Radio Emission VIII
conference) proceeding
Trends and challenges in funding and governance of universities in Europe
Higher education Institutions in the 21st century face grand global challenges, while at the same time many stakeholders have increasing expectations of universities. In Europe universities have been equally facing a complex financial situation in which conventional models of funding have been transformed and continue to evolve. This paper addresses some of the trends observed in the last decade connected to university funding and governance in relation to these global challenges and what kind of reforms are needed at system and institutional level to address the
