Kergosien, Nina. "Instrumentation de plaque composite de type aéronautique pour le contrôle santé intégré." Electronic Thesis or Diss., Ecully, Ecole centrale de Lyon, 2024. http://www.theses.fr/2024ECDL0008.
SHM systems are currently being developed to check the integrity of aircraft composite materials. These systems will help optimize maintenance by enabling real-time monitoring of structural condition, or spot-checking of parts that are difficult to access using conventional NDT methods. Composite materials offer the possibility of integrating a SHM system directly into the material. In this way, the instrumentation is protected from the environment and surface bonding issues are resolved. The aim of this thesis is to determine the effects of integrating piezoelectric transducers into the core of an aeronautical laminated CFRP composite on their Lamb-wave emission and reception abilities, in order to demonstrate the advantages and disadvantages for the design of a defect detection SHM system. Thin PZT transducers proved to be the most suitable ones for integration, as they can withstand the processing conditions of an autoclave-processed composite (7 bar and 180°C). They are also capable of transmitting and receiving guided waves, which are propagating in the plates. Moreover, the integration method was adapted to preserve the integrity of the PZTs and to optimize their ability to transmit waves in a composite. In order to assess the effectiveness of the integration, electromechanical impedance measurements were made a fast checking process. Characterization of qA0 mode wavefield transmitted by embedded PZT was carried out experimentally. Surface-bonded and embedded PZT were excited at frequencies between 30 and 200 kHz, while out-of-plane displacements were measured with a laser vibrometer. The ability of the embedded PZT to detect a simulated magnet-type defect are also studied in pitch-catch tests, and compared with the behavior of surface-bonded PZT to the composite surface. A dynamic finite element modelling study was then conducted to highlight the physical phenomena induced by the integration of a PZT in the composite core. The direction of the plies in contact with the embedded PZT, the depth of integration and the coupling of the PZT with the composite are influencing the ultrasonic transduction mechanism. Furthermore, it appears that the stresses induced by the PZT actuator cannot be simplified by the pin-force model usually used to load a PZT on an isotropic material surface in flaw detection models. These stresses are not radially oriented and depend on the PZT electrode considered, as well as on the wave generation frequencies

Licitra, Floriana. "Pathophysiological and molecular characterization of a mouse model of ARCA2, a recessive cerebellar ataxia associated to Coenzyme Q10 deficiency." Thesis, Strasbourg, 2013. http://www.theses.fr/2013STRAJ096/document.
ARCA2 is a form of recessive ataxia characterized by a slow progression of the ataxic phenotype, cerebellar atrophy and mild deficit in Coenzyme Q10. ARCA2 was recently found associated with mutations in the ADCK3 gene that encodes a putativemitochondrial kinase homologous to the yeast Coq8 and the bacterial UbiB proteins, which are required for Coenzyme Q biosynthesis. In order to elucidate the pathophysiology of ARCA2, a constitutive knockout mouse for Adck3 was generated.Adck3-/- mice reproduce many ARCA2 symptoms such as slow progression of the ataxic phenotype and mild Coenzyme Q deficit, suggesting that Adck3-/- mice are a good model to study ARCA2. Strikingly, a morphological and functional impairmentwas found in cerebellar Adck3-/- Purkinje cells, whereas a mild mitochondrial defect was observed in the skeletal muscle of Adck3-/- mice. Interestingly, transcriptomic analyses revealed alteration in a number of molecular pathways implicating ADCK3in novel cellular processes

Karaki, Muath. "Composition operators on model spaces." Doctoral thesis, Université Laval, 2015. http://hdl.handle.net/20.500.11794/25834.
This thesis concerns the study of composition operators on model spaces. Let φ be an analytic function on the unit disc into itself and let θ be an inner function, that is a holomorphic function bounded by 1 such that the radial limits on the unit circle are of modulus 1 almost everywhere with respect to Lebesgue measure. With this function θ, we associate the model space Kθ, defined as the set of functions f ∈ H2, which are orthogonal to the subspace θH2. Here, H2 is the Hardy space on the unit disc. These subspaces are important in operator theory because they are used to model a large class of contractions on Hilbert space. The first problem which we are interested in concerns the compactness of the composition operator Cφ as an operator on H2 into H2. Recently, Lyubarskii and Malinnikova have obtained a nice criterion for the compactness of these operators which is related to the Nevanlinna counting function. This criterion generalizes the classical criterion of Shapiro. In the first part of the thesis, we generalize this result of Lyubarskii-Malinnikova to a more general class of subspaces, known as de Branges-Rovnyak spaces or some subspaces of them. The techniques that are used are particular Bernstein type inequalities of these spaces. The second problem in which we are interested in this thesis concerns the invariance of Kθ under Cφ. We present a group structure on the unit disc via the automorphisms which fix the point 1. Then, through the induced group action, each point of the unit disc produces an equivalence class which turns out to be a Blaschke sequence. Moreover, the corresponding Blaschke products are minimal solutions of the functional equation ψ∘φ=λψ , where λ is a unimodular constant and φ is an automorphism of the unit disc. These results are applied in the invariance problem of the model spaces by the composition operator.

ARCA2, a rare form of recessive ataxia, is characterized by early onset progressive ataxia, cerebellar atrophy and a mild Coenzyme Q10 deficiency. Most of the patients show additional neurological signs such as epilepsy and exercise intolerance. Mutations in the COQ8A gene lead to ARCA2. COQ8A is suggested as being an unorthodox protein kinase like, with a regulatory role in CoQ biosynthesis, in mammals. To better understand ARCA2, a constitutive Coq8a knock-out (KO) mouse model was generated, which recapitulates most of the patient’s symptoms. Here we report the use of cellular models and the affected tissues to uncover the molecular signature of COQ8A loss and CoQ deficit. Despite CoQ deficit in the muscle, no mitochondrial bioenergetics defect was uncovered. In parallel, we have identified, by RT-qPCR, a key set of genes that are dysregulated in cerebellum, very early on in the pathology. We are currently investigating these pathways to uncover the link with COQ8A function. Altogether, our experiments will shed light on the early molecular events that lead to ARCA2 and may help draw a link between COQ8A function, CoQ pools and the symptoms observed in patients
