Qui est étranger dans l’Union européenne ?

L’Union européenne, construction de ses États membres et des peuples, élabore la citoyenneté européenne comme une “communauté de droits”. Expression démocratique d’un vouloir vivre ensemble, l’Europe se doit de préciser les statuts civils et civiques de ses ressortissants et de protéger, par un statut juridique “aussi proche que possible”, les ressortissants des pays tiers. Ainsi, l’évolution du droit communautaire dissout les distinctions entre ses bénéficiaires, et la citoyenneté européenne..

Proof of concept of energy harvesting from aeroacoustic noise

This paper reports the testing of a new mechanism converting energy radiated from an acoustic source, i.e. a small cavity created on an aircraft outside skin and inducing high frequency oscillations of airflow passing over it. This acoustic noise is then converted into electrical energy. We have submitted in a wind tunnel a set of cavities to an airflow varying the Mach number, creating high sound levels. In a second set of experiments, we have submitted passive microphones to high acoustic levels and stored in capacitors the electrical energy collected at the microphone output. Finally, directions for future work are identified

Rackham: An Interactive Robot-Guide

International audienceRackham is an interactive robot-guide that has been used in several places and exhibitions. This paper presents its design and reports on results that have been obtained after its deployment in a permanent exhibition. The project is conducted so as to incrementally enhance the robot functional and decisional capabilities based on the observation of the interaction between the public and the robot. Besides robustness and efficiency in the robot navigation abilities in a dynamic environment, our focus was to develop and test a methodology to integrate human-robot interaction abilities in a systematic way. We first present the robot and some of its key design issues. Then, we discuss a number of lessons that we have drawn from its use in interaction with the public and how that will serve to refine our design choices and to enhance robot efficiency and acceptability

"Migrants, States, and EU Citizenship's Unfulfilled Promise"

A constant aim of EU citizenship, and indeed the entire project of European integration, has always been to lower barriers and create a common space. If the complete elimination of national borders remains elusive, their importance has been diminished in striking ways by the development of EU citizenship and the ban against nationality based discrimination. Yet the barriers to free movement have been lowered in differential ways. Most citizens of EU member states now enjoy residence, employment and other rights throughout Europe. The extension of some rights to some categories of citizens of some new member states is admittedly sometimes subject to transition periods, but these expire. By contrast, third country nationals -- individuals who do not hold citizenship of one of the member states, even though they may have resided for many years, or even been born in Europe -- remain largely excluded from the benefits of EU citizenship. Various initiatives over the years have opened up limited rights for third country nationals. But the difficulty of enacting these rights, and current moves to more restrictive immigration and naturalization policies, highlight the continuing exclusivity of EU citizenship: immigrants migrate to national polities, and they become European only by virtue of incorporation into national states. This means that EU citizenship's transformative potential remains unrealized.Glendon College (York University
