Full textSingle European Act, Maastricht, Amsterdam, Nice, Lisbon, enlargements… Over a 25-year period, the major revisions of the European Union treaties followed one another at an intensive pace. If that series is necessary for a progressive process of integration, it also illustrates the challenge of reforming the Union. The purpose of this study is to determine the level of rigidity of the European Union Treaties by searching the legal causes, obstacles and consequences of the (in)adaptability of the treaties. Rigidity originates from the constitutionalisation process of the treaties, which consolidated their formal and substantial protection through the emergence of limits to the revision power. The rigidity of the treaties is further increased by that of the ordinary revision procedure, which is based on two notions that may appear antinomic: the respect of the Member States sovereignty (through the plurality of the national mechanisms of ratification), and the willingness of democratisation (through the emergence of European mechanisms of legitimacy). In order to facilitate the adaptability of the treaties, the Member States established simplified procedures, which complement and derogate to the general procedure. As they do not significantly differ from the ordinary revision procedure, they are not efficient; a reconsideration of the rigidity of the treaties can then be observed through the development of an implicit revision of their provisions as well as a cooperation between Member States, the intensity of which is differentiated, and which may grow beside the Union’s institutional framework. Therefore, the pursuit of efficient ways to relax the rigidity of the treaties is necessary to maintain both their position within the legal order and the unity of the European integration process within the framework of the European Union

Full textUndertaken with the LAUM, this work aims at first tocharacterize non linear distortions relative to electrodynamicloudspeakers with a view to miniaturizing units designed in thelaboratory. Furthermore, a special point about the advantages and drawbacks resulting from voltage or current driving has been investigated. After a brief review about the prominent definitions used in thefield of electro-acoustics, the main properties and specificitiesof transducers are discussed while considering at first linear devices. Considering a generic transducer of the state of theart, the main parameters are given in terms of transfer functions. Then, a current-driving policy is discussed whiletaking account of the actual power operational amplifier properties. Furthermore, the rejection of the mechanical resonance is investigated without any kind of alteration of theideal infinity of the Control Drive Index value. Specific filtering structures are calculated regarding a given transducer and considered either in feedforward or feedback arrangements within the circuitry. After such a first order analysis non linear behaviours areconsidered. At first a straightforward typology of non linearsystems is presented so as to highlight the most importantdefinitions. Then, a special analytical approach is given,allowing us to analyse the harmonic generation from a currentdriven loudspeaker with a mono frequency regime. Such anapproach is extended and generalized by way of original numerical models designed with Simulink®, PSpice® and SLPSsoftware, considering bi tonal stimuli signals. Then, such anapproach is considered with transducers and amplifiers of thestate of the art, allowing us to validate the whole relevantrationale. Thus, the micro speakers actually developed in thelaboratory should be investigated and optimized in the shortrun, considering their relevant electronic conditioning policy

Full textDespite their differences, the constitutional legal order, the EU legal order and the ECHR legal order, in progress, are strictly bound. However, this kind or relation is not equal to a fusion. Thus, the relationship of the three orders should be studied through the notions of interdependence and competition. Interdependence is manifest if one takes into account the role of the Constitution as the major vector in the building of Europe, ensuring the integration and the implementation of European rights in the national legal order. Hence, the Hellenic Constitution responds to the European rationale and both European legal orders contribute in the enrichment of the national legal order. Likewise, competition is manifest as the national constitutional order is seized by the European orders and its weaknesses appear as conflict sources with them. Therein, a forced transformation of the domestic law is apparent in order to adapt to the European conditions. This conflict situation gives rise to the research of an institution-based solution. A systematic approach of European influences in the national legal order is used in order to reinforce the authority of the Constitution and to restructure the procedural system. While the complexity of the aforementioned orders appears undoubtful, one should stress the institutional and procedural means that allow to favour complementarity and to mitigate competition between these orders

Full textDrying shrinkage induced cracking is an essential mechanism to be considered in the durability study of cement-based materials and structures. The present thesis is devoted to experimental investigation and numerical modeling of this mechanism by putting the emphasis on the influences of inclusion stiffness and size. The thesis is composed of two parts.The first part is devoted to experimental study. A series of concrete samples are first casted with artificial inclusions of different rigidities. These samples are subjected to different levels of drying in order to evaluate cracks induced by the drying shrinkage. The dried samples are then examined by using the non-destructive X-ray micro-tomography imaging method. Three-dimensional (3D) distributions of induced cracks in the dried samples are identified, including their location and shape. The influence of inclusion rigidity on the shrinkage induced cracking process is clearly demonstrated. It is found that the shrinkage-induced cracking is strongly enhanced by the stiffness difference between the inclusion and cement paste. Secondly, samples casted with glass balls of different sizes are considered. By using a similar experimental procedure, the influences of inclusion size on the drying shrinkage induced cracking process are investigated.In the second part, a numerical method based on the peridynamics theory is proposed. The formulation and implementation of the numerical method are first presented and discussed. Its efficiency in modelling the initiation and propagation of multiple cracks in heterogeneous materials is then demonstrated. The proposed method is further applied to the description of cracking process induced by drying shrinkage and temperature change in concrete composites containing different types of inclusions. The emphasis is put on the effects of inclusion stiffness and size on cracking patterns. A series of numerical simulations are performed. Comparisons between numerical results and experimental observations are presented
Schiano, Fabrizio. "Bearing-based localization and control for multiple quadrotor UAVs." Thesis, Rennes 1, 2018. http://www.theses.fr/2018REN1S009/document.
Full textThe aim of this Thesis is to give contributions to the state of the art on the collective behavior of a group of flying robots, specifically quadrotor UAVs, which can only rely on their onboard capabilities and not on a centralized system (e.g., Vicon or GPS) in order to safely navigate in the environment. We achieve this goal by giving a possible solution to the problems of formation control and localization from onboard sensing and local communication. We tackle these problems exploiting mainly concepts from algebraic graph theory and the so-called theory of rigidity. This allows us to solve these problems in a decentralized fashion, and propose decentralized algorithms able to also take into account some typical sensory limitations. The onboard capabilities we referred to above are represented by an onboard monocular camera and an inertial measurement unit (IMU) in addition to the capability of each robot to communicate (through RF) with some of its neighbors. This is due to the fact that an IMU and a camera represent a possible minimal, lightweight and inexpensive configuration for the autonomous localization and navigation of a quadrotor UAV

Full textElectrostatic complexation process involving polyelectrolyte and nanoparticles of opposite charge are receiving an increasing interest in view of their implications in numerous domains. In this thesis, we are particularly interested in the role of ratio LP/R on the formation of complexes. To realize the variation of this parameter, we have chosen five model Systems by the combination of four polyelectrolytes of différent rigidity and three oppositely charged nanoparticles of different sizes, including the positively charged AuNPs synthesized by ourselves. For each System, we have in the first place studied the macroscopic behaviors of complexes formed at different concentration ratio of PEL and NPs, which were recorded in the phase diagrams. Then, the structures of so formed complexes were studied by a combination of cryo-TEM, small-angle neutron, X-ray, and light scattering (size, fractal dimension Df). We have in particular revealed for Lp/R ~1 the formation of well-defined single-strand nanorods and also of randomly branched complexes (Df between 1. 5 and 3) respectively in the two monophasic domains (excess of nanoparticles or of PEL chains). Besides the ratio LP/R, the salt effect was also studied by comparing salt-free System with the one in presence of additional salt, and we proved that the addition of salt can screen the repulsive charges of complexes which results in rapid phase separation and more compact complex structure. Moreover, we have observed unexpectedly the formation of AuNPs nanoparticles- Hyaluronan chains metacrystals

Full textThis thesis is positioned in the context of the tension between the organizational purpose as intentionally defined by the top manager and internalized by the management, and the mobilization or not of the singularities of operational employees to contribute to the alignment on the expected effects. More precisely, our work aims to explore the link, and the underlying tensions, between the consideration of singularities, linked to professional and personal background, in learning, and the real alignment of the uses of new information systems (IS) in the presence of an operational novelty (unanticipated, unexpected). The literature review has led us to gradually raise several tensions: between robust, structuring and new operational information systems; between user and organizational singularities in the alignment of uses against the new; between user and organizational singularities in learning to overcome the new and contribute to alignment. Our reflection has gradually shifted towards a questioning not dealt with in the literature, apart from insights into the educational sciences: how, and in what tensions, does the organisation take into account the singularities of users in the design and implementation of learning make it possible to overcome the unprecedented with efficiency in order to contribute to the alignment of the uses of new IS with the expected organisational and managerial effects? Our exploratory process continued in the field guided by subquestions that constitute our questioning. The data collection by semi-directive interviews was carried out with different targets (company manager, manager, human resources manager, trainer, user). The qualitative analysis provided additional insights. The results confirm the interest of focusing on individual singularities but also the lack of consideration in the organisation, in the tensions linked to the vision of the new unanticipated, of alignment, of the individual, of learning, in the tension between control and autonomy. Is it a denial of the individual? of the real novelty? of an organized learning vision, intended to acquire skills according to reference frames, and not the development of the ability to "face"? of a vision of alignment aiming at compliance with the prescribed and not "doing it in addition"?
