    ABSTRACT Linked data have made significant progress over the last few years and many kinds of datasets are transformed into this format at a highly increasing rate, contributing to the openness, connectivity and re-use of web data. However, this progress is not the case for a popular sport like basketball, at least as far as the raw statistics is concerned. This kind of data contains valuable information that can be used by fans, teams and coaches, statisticians and other scientists. In this work, statistical data from Euroleague are transformed into linked data, thereby filling the relevant gap in the LOD Cloud, while ways of exploitation of them are presented, from fascinating applications for the fans, like the Euroleague Timeline, to cases of complex processing, analysis and visualization of data through software like R

    Towards a Stable Numerical Evolution of Strongly Gravitating Systems in General Relativity: The Conformal Treatments

    We study the stability of three-dimensional numerical evolutions of the Einstein equations, comparing the standard ADM formulation to variations on a family of formulations that separate out the conformal and traceless parts of the system. We develop an implementation of the conformal-traceless (CT) approach that has improved stability properties in evolving weak and strong gravitational fields, and for both vacuum and spacetimes with active coupling to matter sources. Cases studied include weak and strong gravitational wave packets, black holes, boson stars and neutron stars. We show under what conditions the CT approach gives better results in 3D numerical evolutions compared to the ADM formulation. In particular, we show that our implementation of the CT approach gives more long term stable evolutions than ADM in all the cases studied, but is less accurate in the short term for the range of resolutions used in our 3D simulations.Comment: 17 pages, 15 figures.

    TECHNOLOGY-CHANGE CHANGES: IMPLICATIONS FOR UNIVERSITIES AND R&D-SECTOR

    Abstract: Technology change and the resulting increase in labour's productivityis the major contribution of bourgeoisie. Yet, as the path and the velocity of technology's evolution changes, the phenomenon induces systemic modifications challenging the very nature of capitalism itself. This in turn alters the role of the R&D and academic institutions in the modern society. The present paper contributes to this discussion. We follow a theoretical framework that combines epistemological and economic growth theories in order to suggest the induced changes. Next we discuss the modern role of academia and R&D. We conclude by presenting hypotheses for further research and discussing the induced policy implications
