We build a simple model of secession crises where a majority of voters may wish to accommodate a minority in order to prevent a secession attempt. We first show the existence of a majority voting equilibrium, where the median voter is decisive and most prefers a government’s type that is biased in favor of the minority. We propose a measure of the secession risk at equilibrium, which depends upon the comparison of the willingness to secede by the minority and to accommodate by the majority. We show that focusing only on the willingness to secede, as previous literature has done, is misleading when studying the impact on the risk of secession of the size of the minority region, the probability that a secession attempt by the minority is successful, and the cultural heterogeneity in the country.

Au sein de l’Union européenne, le Luxembourg est le pays qui peut se targuer de la plus longue expérience d’intégration économique et politique – 170 ans. Au sortir de la Seconde Guerre mondiale, l’implication active du Grand-Duché dans ce processus fut le fruit d’un choix délibéré, motivé par sa situation géopolitique et économique, par sa nature de petit État et par une conviction profonde. Effectivement, le Luxembourg s’est toujours illustré comme médiateur et force de proposition pour l’Europe unie, que ce soit en tant qu’État, à travers ses personnalités, ou par l’action de diverses associations, dont la Fondation du Mérite Européen occupe une place de choix depuis un demi-siècle.

Le voyage des bénéficiaires de la protection internationale dans leur pays d'origine: défis, politiques et pratiques au Luxembourg

Cette note de synthèse présente les principaux résultats de l’étude réalisée en 2018 par le point de contact luxembourgeois du Réseau européen des migrations intitulée « Les bénéficiaires de la protection internationale qui voyagent dans leur pays d’origine: défis, politiques et pratiques ». Dans plusieurs Etats membres de l’Union européenne, les autorités ont détecté des bénéficiaires de protection internationale (ci-après bpi) ayant voyagé dans leur pays d’origine ou demandé un passeport à l’ambassade ou consulat de leur pays d’origine. Si ces actes ne représentent pas nécessairement un abus du droit à la protection internationale, ils pourraient, dans certains cas et dans certaines circonstances, amener les autorités à considérer que les raisons d’octroi de la protection internationale ont cessé d’exister : à savoir la crainte fondée de persécution dans le pays d’origine pour le réfugié ou le risque réel d’y subir des atteintes graves pour le bénéficiaire de la protection subsidiaire. L’étude vise à apporter un éclairage sur les défis liés à la détection de ce phénomène et s’intéresse aux éventuelles conséquences de ces actes sur le statut de protection internationale, en particulier la cessation du statut qui pourrait en résulter.

Making personal data anonymous is crucial to ensure the adoption of connected vehicles. One of the privacy-sensitive information is location, which once revealed can be used by adversaries to track drivers during their journey. Vehicular Location Privacy Zones (VLPZs) is a promising approach to ensure unlinkability. These logical zones can be easily deployed over roadside infrastructures (RIs) such as gas station or electric charging stations. However, the placement optimization problem of VLPZs is NP-hard and thus an efficient allocation of VLPZs to these RIs is needed to avoid their overload and the degradation of the QoS provided within theses RIs. This work considers the optimal placement of the VLPZs and proposes a genetic-based algorithm in a software defined vehicular network to ensure minimized trajectory cost of involved vehicles and hence less consumption of their pseudonyms. The analytical evaluation shows that the proposed approach is cost-efficient and ensures a shorter response time. [less ▲]

VPS-SLAM: Visual Planar Semantic SLAM for Aerial Robotic Systems

Indoor environments have abundant presence of high-level semantic information which can provide a better understanding of the environment for robots to improve the uncertainty in their pose estimate. Although semantic information has proved to be useful, there are several challenges faced by the research community to accurately perceive, extract and utilize such semantic information from the environment. In order to address these challenges, in this paper we present a lightweight and real-time visual semantic SLAM framework running on board aerial robotic platforms. This novel method combines low-level visual/visual-inertial odometry (VO/VIO) along with geometrical information corresponding to planar surfaces extracted from detected semantic objects. Extracting the planar surfaces from selected semantic objects provides enhanced robustness and makes it possible to precisely improve the metric estimates rapidly, simultaneously generalizing to several object instances irrespective of their shape and size. Our graph-based approach can integrate several state of the art VO/VIO algorithms along with the state of the art object detectors in order to estimate the complete 6DoF pose of the robot while simultaneously creating a sparse semantic map of the environment. No prior knowledge of the objects is required, which is a significant advantage over other works. We test our approach on a standard RGB-D dataset comparing its performance with the state of the art SLAM algorithms. We also perform several challenging indoor experiments validating our approach in presence of distinct environmental conditions and furthermore test it on board an aerial robot.

The 3-dimensional representation and inspection of complex data is a frequently used strategy in many data analysis domains. Existing data mining software often lacks functionality that would enable users to explore 3D data interactively, especially if one wishes to make dynamic graphical representations directly viewable on the web. In this paper we present vrmlgen, a software package for the statistical programming language R to create 3D data visualizations in web formats like the Virtual Reality Markup Language (VRML) and LiveGraphics3D. vrmlgen can be used to generate 3D charts and bar plots, scatter plots with density estimation contour surfaces, and visualizations of height maps, 3D object models and parametric functions. For greater flexibility, the user can also access low-level plotting methods through a unified interface and freely group different function calls together to create new higher-level plotting methods. Additionally, we present a web tool allowing users to visualize 3D data online and test some of vrmlgen's features without the need to install any software on their computer. [less ▲]
