A Generic Information and Consent Framework for the IoT

The Internet of Things (IoT) raises specific issues in terms of information and consent, which makes the implementation of the General Data Protection Regulation (GDPR) challenging in this context. In this report, we propose a generic framework for information and consent in the IoT which is protective both for data subjects and for data controllers. We present a high level description of the framework, illustrate its generality through several technical solutions and case studies, and sketch a prototype implementation

Bayesian Inference from Composite Likelihoods, with an Application to Spatial Extremes

Composite likelihoods are increasingly used in applications where the full likelihood is analytically unknown or computationally prohibitive. Although the maximum composite likelihood estimator has frequentist properties akin to those of the usual maximum likelihood estimator, Bayesian inference based on composite likelihoods has yet to be explored. In this paper we investigate the use of the Metropolis--Hastings algorithm to compute a pseudo-posterior distribution based on the composite likelihood. Two methodologies for adjusting the algorithm are presented and their performance on approximating the true posterior distribution is investigated using simulated data sets and real data on spatial extremes of rainfall

Aux marges méridionales de la Franche-Comté, un "pays" un peu oublié: la Petite Montagne

Dans l'ensemble du massif jurassien, la Petite Montagne occupe une place à part. Son originalité, elle la doit certes à la diversité et à la richesse de son milieu naturel, mais aussi à l'organisation du peuplement et des activités humaines. Jadis florissant, ce petit pays connaît, depuis des décennies, une crise économique et sociale dont on voit mal l'issue, malgré les nombreux efforts déployés pour lui redonner vie

Des crues et des hommes: le cas de la Savoureuse dans le Territoire de Belfort

Les crues constituent des épisodes majeurs dans la dynamique des cours d'eau. À l'échelle d'une vie humaine, elles apparaissent comme des événements exceptionnels par leur rareté, leur soudaineté et l'ampleur des volumes d'eau mis en jeu ; la brutale montée des flots s'accompagnant souvent de débordements. Dans des espaces densément peuplés, les inondations prennent alors l'allure de catastrophes provoquant des dégâts matériels et mettant en péril les vies humaines. Aussi, de tout temps, les hommes ont tenté, avec des fortunes diverses, de se préserver contre de tels risques

Proto-TGO formation in TBC systems fabricated by spark plasma sintering

Thermal barrier coatings (TBC) are commonly used in modern gas turbines for aeronautic and energy production applications. The conventional methods to fabricate such TBCs are EB-PVD or plasma spray deposition. Recently, the spark plasma sintering (SPS) technique was used to prepare new multilayered coatings. In this study, complete thermal barrier systems were fabricated on single crystal Ni-based superalloy (AM1®) substrate in a one-step SPS process. The lifetime of TBC systems is highly dependent on its ability to form during service a dense, continuous, slow-growing alumina layer (TGO) between an underlying bond coating and a ceramic top coat. In the present paper, we show that such kind of layer (called proto-TGO in the following) can be in situ formed during the SPS fabrication of TBC systems. This proto-TGO is continuous, dense and its nature has been determined using TEM-EDS-SAD and Raman spectroscopy. This amorphous oxide layer in the as-fabricated samples transforms to α-Al2O3 during thermal treatment under laboratory air at 1100 °C. Oxidation kinetics during annealing are in good agreement with the formation of a protective α-Al2O3 laye
