Texte intégralIn the Ionian Sea (central Mediterranean) the slow convergence between Africa and Eurasia results in the formation of a narrow subduction zone. The nature of the crust of the subducting plate remains debated and could represent the last remnants of the Neo-Tethys ocean. The origin of the Ionian basin is also under discussion, especially concerning the rifting mechanisms as the Malta Escarpment could represent a remnant of this opening. This subduction retreats toward the south-east (motion occurring since the last 35 Ma) but is confined to the narrow Ionian basin. A major lateral slab tear fault is required to accommodate the slab rollback.This fault is thought to propagate along the eastern Sicily margin but its precise location remains controversial.This PhD project focussed on the deep sedimentary and crustal structures of the eastern Sicily margin and the Malta Escarpment (ME). Two two-dimensional P wave velocity models were modelled by forward Modelling of wide-angle seismic data, acquired onboard the R/V Meteor during the DIONYSUS cruise in 2014.A 3D gravity model of the region was also performed to constrain the depth of the subducting slab bellow the Calabro-Peloritan backstops. The seismicity of the three structures identified in the velocity models (ME, Alfeo fault System, Ionian Fault System) permits to study their recent activity. The results image an oceanic crust within the Ionian basin as well as the deep structure of the Malta Escarpment, which presents characteristics of a transform margin. A deep and asymmetrical sedimentary basin is imaged south of the Messina strait and seems to have opened between the Calabrian and Peloritan continental terranes. In the western lobe of the Calabrian accretionary prism, the southern velocity model allows to observe the indentation of the internal clastic wedge into the external evaporitic wedge, thus showing the recent activity of this lobe. The interpretation of the velocity models suggests that the major STEP fault is located east of the Malta Escarpment, along the Alfeo Fault System

Texte intégralShape memory alloys (SMA) are metallic materials that have particular thermomechanical properties, including the shape memory effect. The study carried out during the thesis concerns the creation of two-way active systems using SMA wires exhibiting one-way memory effect. Three simple analog models, representing three classes of constructive solutions, have been developed. These models correspond to different types of mechanical coupling between one (or more) SMA wire(s) and a mechanical structure. For example, the simplest configuration is a single SMA wire coupled to a mechanical system consisting of a deformable monolithic structure. When the SMA is heated, the shape memory effect is activated, which causes the deformation of the structure. When cooling the SMA, the inherent rigidity of the structure causes a deformation in the opposite direction to that of the heating phase. Several demonstrators were also constructed and analyzed during the thesis. This study demonstrates the possibility of designing active structures driven by SMAs, which opens prospects for the control of deformations or stresses in structures

Texte intégralThe transport of microorganisms and biological fluids by means of cilia and flagella is an universal phenomenon found in almost all living beings. The aim of this thesis is to model, analyze and simulate mathematical fluid-structure interaction problems involving active structures, capable of deforming themselves through internal stresses, and a low Reynolds number fluid, modeled by Stokes equations. In Chapter 2, these active structures are modeled as elastic materials satisfying Saint Venant-Kirchhoff law for elasticity whose activity comes from the addition of an activity term to the second Piola-Kirchhoff stress tensor. Elasticity and Stokes equations are coupled on the fluid-structure interface and the mathematical study of the linearized problem discretized in time is realized. Then, the problem is formulated as a saddle-point problem which isused for numerical simulations. Chapter 3 focuses on the analysis of a quasi-static fluid-structure with an active structure, for which we show existence and uniqueness, for small data, of a strong solution locally in time. Chapter 4 presents a new fictitious domain method (the smooth extension method) for the numerical resolution of transmission problems. The method is first developed for a Laplace transmission problem and further extended to Stokes transmission and fluid-structure interaction problems

Texte intégralThe need of optical fiber telecommunication systems has been the driving force for the tremendous development of integrated optical circuits (IOCs) with a vast number of technologies which are up to now incompatible. However, the integration of elementary functionson a single wafer seems to be required to reduce the dimension and the cost for future complex IOCs. Ln this perspective, we propose in this report the realization of hybrid structures on glass. These latter consist of a passive or active thin guiding layer on a glass wafer containing an ion-exchanged channel waveguide. This work has mainly been devoted to the study and the realization of an hybrid optical amplifier by wafer bonding and ion-exchange techniques. First, a T1+/K+ ion-exchange process has been developed in a passive silicate glass with the aim of keeping a fiat glass surface. Then, an Er3+/Yb3+ codoped phosphate glass layer with a thickness below 10 μm has been formed by a low temperature wafer bonding process (<150°C) foIlowed by a polishing thinning procedure. The realized hybrid structure has been characterized and a promising gain coefficient of 3. 66 dB/cm has been reached which is comparable with the best published values for standard ion-exchanged optical amplifiers. This result has been improved thanks to the implementation of an Ag+/Na+ ion-exchange and a grinding/polishing process and net gain operation has been demonstrated. Other hybrid structures have also been studied : a glass surface- and polarization-insensitive embedded Bragg filter and an hybrid optical isolator. Finally, the necessary future works for the integration of aIl hybrid structures on a single wafer have been described

Texte intégralThe resistance of microorganisms to antibiotics is, in our days, one of the biggest problems in terms of public health. The research for new artificial and natural families of compounds throws us towards innovative methodologies leading to novel antibiotics.In the present work, we are invited to dive in the “new world” of 1,3-oxazoline-2-thiones (OXTs) synthesis, reactivity and biological activity. In fact, this unexplored heterocycle is a simple synthon readily obtained by condensation of thiocyanic acid with an _-hydroxycarbonyl species. When the heterocycle is anchored on a carbohydrate template, original structures are expected such as OZTs fused to five- or six-membered rings and OXTs C-C linked to sugars, with a broad potential in organic chemistry and bioorganic applications. We have then investigated the synthesis and reactivity of simple OXT and thionocarbamates fused or linked to carbohydrate templates, leading to the formation of new carbohydrate-fused oxazolidinones (OZOs) as well as pseudo-C-iminosugars and oxazoles. We have also explored the use of thioxo compounds as electrophiles in Pd-assisted cross-coupling methods, such as Suzuki and Stille reactions. A new modified Sonogashira cross-coupling reaction, in which copper (I) is used in catalytic amount, was developed and its feasibility was proven for a variety of substrates. Finally, our attention was focused on the biological potential of the new molecules. We have targeted a broad spectrum of antimicrobial activity for some OXTs and OZTs, to which was added a screening of glycosidases inhibition for the pseudo C-iminosugars
