Повний текст джерелаHydroformed flexible tubes are essential structures used in several industrial sectors such as the automotive sector, the aviation industry or energy production, such as the production of renewable energy in solar thermal energy farms where the panels must both be supplying fluid along and follow the direction of the sun. These structures serve as connecting parts between the rigid parts different mechanisms, primarily used for damping vibrations and acoustic emissions, and, as their name suggests, they also allow flexibility and pressure expansion, which considerably improves the fatigue strength. The mastery and prediction of the mechanical behavior of these structures are very important from a safety point of view and an economic point of view. Indeed, their accidental breakage can cause very serious consequences due to their use in sensitive areas such as the nuclear industry. In this context, this thesis was launched between Compiegne University of Technology and industrial BOA-group to create digital approaches to behavioral predictions and estimating the life braided hoses that take into account extreme conditions (temperature and pressure) and the forming parameters and properties of the materials used. In terms of use, these products are subject to thermomechanical charge-discharge cycles and vibrations can induce complex deformed piping of wear due to friction and damage by fatigue, The purpose of the study is to develop a numerical approach validated by the experience to certify products and improve the design. This approach will allow to estimate the lifetime of braided wavy taking into account: - the initial state of the product after forming and assembly, - thermomechanical stresses, is defined by the specification, or encountered in specific use cases, - vibrations encountered during use in real cases. The expected results are the life of the products from a calculation model of their behavior using the characteristics of the materials and interaction braid / tube

Повний текст джерелаIn the context of the development of efficient, low-cost and environmentally friendly photovoltaic devices, the synthesis of metal-oxide semiconductors such as SnO2, Zn2SnO4 and WO3 with various textures and morphologies have been developed in order to achieve nanoporous photoanodes for dye-sensitized solar cells. According to studies carried out by different characterization methods (SEM, TEM, XRD and BET), the resulting materials show interesting features for the expected application. Dye solar cells were then fabricated from photoanodes processed with these oxides and several parameters influencing their performance were optimized to improve the overall conversion efficiency. In particular, the beneficial effect of different treatments of the photoanodes (ie aqueous TiCl4 or water treatment) on the power conversion efficiency and the stability of the devices has been evidenced. Thus, state-of-the art or, even, record efficiencies were reached in the case of SnO2-based systems. These performances were then rationalized by determining the electronic and ionic processes occurring in these devices by various physical methods (threshold voltage and open-circuit photovoltage decay measurements, electrochemical impedance spectroscopy). Finally, electrodes based on WO3 and deposited on flexible substrates have shown very promising electrochromic properties, which opens up new prospects in the field of smart displays

Повний текст джерелаEsta tese pretende apresentar o trabalho desenvolvido na preparação de novos Polímeros de Coordenação ou Redes Metalo-Orgânicas de baixa dimensão (1D e 2D) pela auto-montagem de lantanídeos e ligandos orgânicos altamente flexíveis. Numa primeira etapa as condições ideais foram optimizadas utilizando abordagens sintéticas distintas: condições hidrotérmicas e de one-pot, o que permitiu o isolamento de cristais grandes; e a síntese por microondas, que foi a abordagem ideal para reduzir significativamente o tempo de reacção. Todos os materiais foram caracterizados utilizando a combinação de várias técnicas, como FTIR, análise elementar, RMN de estado sólido, microscopia electrónica (SEM e EDS) e termogravimetria. As estruturas cristalinas foram resolvidas utilizando análise de difracção de raios X de cristal único. Num segundo passo, os materiais de baixa dimensão foram utilizados como precursores para obter MOFs de dimensão superiores por transformação Cristal- Cristal, que foram seguidos de perto por análise de raios-X de cristal único. No último passo, as propriedades de alguns materiais foram investigadas, como o uso como potencial catalisadores heterogéneos e como condutores protónicos. Alguns materiais mostraram actividade catalítica notável em várias reacções orgânicas, enquanto um mostrou a maior condução protónica registada até agora para qualquer tipo de material.
This thesis aims to present the work developed in the preparation of new Coordination Polymers or Metal-Organic Frameworks with low dimensions (1D and 2D) by the self-assembly of lanthanides and highly flexible organic linkers. In a first step the ideal conditions were screened using distinct synthetic approaches: hydrothermal and one-pot conditions, which allowed the isolation of large crystals; and microwaveassisted synthesis, which was the ideal approach to reduce significantly the time of reaction. All materials were characterized using the combination of several techniques, such as FTIR, elemental analysis, solid-state NMR, electron microscopy (SEM and EDS) and thermogravimetry. The crystal structures were unveiled using singlecrystal X-ray diffraction analysis. In a second step, the low dimensional materials were used as precursors to obtain higher dimensional MOFs by Single-Crystal to Single-Crystal transformation, which were followed closely by single-crystal X-ray analysis. In a final step, the properties of some materials were investigated, with potential use as heterogeneous catalysts and proton conductors. Some materials showed remarkable catalytic activity in several organic reactions, while one showed the highest proton conduction registered up to now for any kind of material

The flexible metal to metal face seals (FMMFS) has unique features including much more flexibility in the circumferential direction than in the radial direction, identical rotating and stationary seals, and a loading mechanism using elastomeric rings. This thesis work is the first attempt to explain scoring failures of this unique type of mechanical face seal. Numerical models and new scoring failure criteria were developed to explain different scoring failures of the FMMFS. The numerical models consider interactions among seal surface deflections, lubrication in the sealing band and thermal effects simultaneously. The numerical models were validated from comparisons with experiments and applied to scoring failure tests. The new scoring failure criterion successfully predicted the likelihood of scoring failures for each seal pair at given loads and speeds. From in-depth analysis of the seal pairs with low and high scoring failure speeds, it has been shown that discontinuous contact patterns can increase scoring resistance of the seal pair. These discontinuous contact patterns are created by irregular surface profiles of the sealing band. Irregular surface profiles can decrease high temperature regions by reducing superposition of temperatures and thermal conduction resistance, and finally delay scoring failures.

Повний текст джерелаThe present production of energy that mainly comes from the burning of fossil fuels has a negative impact on our environment. The research and development of clean and renewable sources of energy can decrease this damage. If the thermodynamic conversion from solar energy obtained by photons radiation concentration allows us a higher efficiency, the challenge is to build at low cost, large areas for solar reflectors that are flexible and lightweight, with a powerful optical reflection.During this research a study was made on two types of mirrors for achieving solar concentrators. The first mirror is formed of a flexible polymer plate highly transparent (Transmission index as high as possible) in which was deposited a reflective layer. This layer is protected against corrosion and any other environmental aggression by an opaque organic coating built on the rear face. This produces a polymer/metal/organic film system. The second mirrors consist of a flexible opaque substrate in which, a reflective film is deposited. A thin organic or ceramic protector film with a transmission index as high as possible is prepared in front of the reflective layer. Thereby, a ceramic/metal/organic system was obtained.Being that the reflective layer is essential in both configurations of the mirror, research was carried out about the development of a reflective layer composed of silver with the dynamic chemical plating technique also called “Jet MetalTM technique” which allows the elaboration of silver films at room temperature in a fast and economical manner. Also, this approved technology <> is well adapted for the deposit development over large surfaces. This report describes the steps and necessary parameters to obtain optical reflectors based on high quality silver: optical quality with a higher reflectivity over 95%, mechanical quality with interfaces of polymer / metal that can absorb deformations, a relation quality/price through the optimization of the deposit kinetic and the silver film thickness (approximately 100 nm) with a very short elaboration time. Many analysis and characterization techniques (XPS, AFM, LRX, SEM…) have been performed to determine the parameters of a solar mirror made of silver.The optical property of the silver film is stable in air ambient and with time. However; the silver protection is necessary mainly on the front face. This protection must adhere to the silver film, be flexible and provide a high visual range. Different varnishes have been researched, and our work has been concentrated in the development of organic (PMMA, PU), ceramics (SiO2, Al2O3), and especially hybrid organic-ceramic covering protection. This research allowed us to identify the relevant areas of these different types of protection coatings under radiation stress, its compatibility with the silver layer to obtain efficient and flexible concentrators. An original solution is presented at the conclusion that corresponds in the elaboration of a flexible mirror, made up of a glass layer of 100 µm thick and covered in a silver film of 100 nm. The reflection is over 95% visible
La producción actual de energía que proviene principalmente de combustibles fósiles tiene un impacto negativo sobre el medio ambiente. El desarrollo de las energías renovables puede reducir este impacto. Si la conversión termodinámica de la energía solar obtenida por concentración de radiación de fotones permite alcanzar altos rendimientos, el reto es lograr realizar, a bajos costos, grandes áreas de reflectores flexibles y ligeros, con una excelente propiedad óptica reflejante.En esta investigación, se estudiaron dos tipos de espejos que intervienen en la consecución de los concentradores solares. El primer espejo está hecho de una placa flexible de polímero altamente transparente (índice de transmisión lo más alta posible) en el que se depositó una película reflejante. Esta capa está protegida contra la corrosión y el ataque del medio ambiente por un revestimiento orgánico opaco desarrollado en la parte trasera. Esto produce un sistema polímero/metal / película orgánica. El segundo espejo consiste en un sustrato opaco flexible en la que se deposita una película reflejante. Una película delgada y protectora orgánica o cerámica con un índice de transmisión lo más alto posible se prepara en frente de la capa reflejante. Por lo tanto, se obtiene un sistema cerámico / metal / orgánico.Siendo esta capa reflejante esencial en ambas configuraciones de espejo, se investigó el desarrollo de una capa reflejante a base de plata con la técnica de depósito químico dinámico, también llamada “JetMetalTM technique” que permite elaborar películas de plata a temperatura ambiente de manera rápida y económica. Además, esta tecnología, aprobada « Green Tech », está bien adaptada para el desarrollo de depósitos sobre superficies grandes. Este trabajo describe los pasos y los parámetros necesarios para obtener reflectores ópticos basados en plata de grandes cualidades: calidad óptica con reflectividad mayor a 95%, calidad mecánica con interfaces de polímero / metal que pueden absorber deformaciones, una relación calidad / precio mediante la optimización de la cinética de depósito y espesor de la película de plata (aproximadamente 100 nm) con un tiempo corto de elaboración. Numerosas técnicas de análisis y caracterización (XPS, AFM, LRX, SEM ...) han sido utilizadas para determinar los parámetros pertinentes de un espejo solar a base de plata. La propiedad óptica de la película de plata es estable en el aire y en el tiempo. Sin embargo, la protección de la plata es necesaria, en particular en el frente. Esta protección debe adherirse a la película de plata, ser flexible y proporcionar un índice de transmisión lo más alto posible en el rango visible. Se han estudiado diferentes barnices y nuestro trabajo ha sido centrado en el desarrollo de recubrimientos de protección orgánicos (PMMA, PU), cerámicos (SiO2, Al2O3) y especialmente en híbridos orgánico-cerámica. Esta investigación ha permitido identificar las áreas de relevancia de estos diferentes tipos de recubrimientos de protección bajo estrés por radiación y su compatibilidad con una capa reflejante de plata para obtener concentradores flexibles eficientes. Una solución original se presenta en la conclusión y corresponde en la realización de un espejo flexible elaborado en una hoja de vidrio de 100 µm de espesor y recubierto con una película de plata de 100 nm. La reflectividad es superior a 95% en el visible

Повний текст джерелаThe increasing interest in the THz region (0.1-10 THz) for applications like imaging, spectroscopy and wireless communications is leading to a strong development of devices for the generation and detection of THz waves. Uni-travelling carrier photodiodes (UTC-PDs) are one of the main sources due to their broadband behavior (0-3 THz), room temperature operation, driving wavelength of 1.55 µm and compactness. Their main drawback comes from the low output RF powers at high frequencies (order of µW at 1 THz). A technique to increase their RF powers consists in using higher optical driving powers. However, this solution may lead to their failure because of heating, especially in case of unwanted absorption.In the first part of the thesis an electrical contact based on sub-wavelength apertures has been developed to reduce this issue. This solution has been shown valuable under multiple aspects. It provides good electrical, optical and thermal properties, while leading to an easier process in terms of fabrication and characterization with respect to previous works.A second drawback of UTC-PDs is due to their non-linear behavior which leads to a noise at low frequency because of the broad spectrum of the driving optical signals. This issue is critical for measurements at high frequencies with incoherent detectors due to the low RF powers to be detected.In the second part of the thesis a high-transparency broadband high-pass mesh filter has been developed on a novel low-loss dielectric material to filter-out this noise. The developed process can be exploited in other free-space devices like metamaterials due to the remarkable properties of this dielectric at THz frequencies

Повний текст джерелаThe increase of software complexity along the years has led researchers in the software engineering field to look for approaches for conceiving and designing new systems. For instance, the service-oriented architectures approach is considered nowadays as the most advanced way to develop and integrate fastly modular and flexible applications. One of the software engineering solutions principles is re-usability, and consequently generality, which complicates its appilication in systems where optimizations are often used, like real-time systems. Thus, create real-time systems is expensive, because they must be conceived from scratch. In addition, most real-time systems do not beneficiate of the advantages which comes with software engineering approches, such as modularity and flexibility. This thesis aim to take real time aspects into account on popular and standard SOA solutions, in order to ease the design and development of modular and flexible applications. This will be done by means of a component-based real-time application model, which allows the dynamic reconfiguration of the application architecture. The component model will be an extension to the SCA standard, which integrates quality of service attributs onto the service consumer and provider in order to stablish a real-time specific service level agreement. This model will be executed on the top of a OSGi service platform, the standard de facto for development of modular applications in Java

Повний текст джерелаIn this work, we study how the notion of behavioral habit, inspired from the study of biology, can benefit to robots. Robot control architectures allow the robot to be able to plan to reach long term goals while staying reactive to events happening in the environment (Kortenkamp et Simmons, 2008). However, these architectures are rarely provided with learning capabilities that would allow them to acquire knowledge from experience. On the other hand, learning has been shown as an essential abiilty for behavioral adaptation in mammals. It permits flexible adaptation to new contexts but also efficient behavior in known contexts (Dickinson, 1985). The learning mechanisms are modeled as model-based (planning) and model-free (habitual) reinforcement learning algorithms (Sutton et Barto, 1998) which are combined into a global model of behavior (Daw et al., 2005). We proposed a robotic control architecture that take inspiration from this model of behavior and embed the two kinds of algorithms, and studied its performance in a robotic simulated task. None of the several methods for combining the algorithm we studied gave satisfying results, however, it allowed to identify some properties required for the planning process in a robotic task. We extended our study to two other tasks (one being on a real robot) and confirmed that combining the algorithms improves learning of the robot's behavior

Повний текст джерелаLos sensores de gas se utilizan para monitorear ambientes interiores y exteriores. Algunas aplicaciones comunes son para medir: el nivel de contaminantes en las calles, los gases liberados por los escapes industriales y de automóviles, los gases en la minería, el contenido de alcohol en la sangre a través del aliento exhalado, etc. A medida que crece el campo de aplicación de los sensores de gas, se hace necesario adaptar los sensores de gas a nuestros dispositivos y pertenencias diarias. Se requieren materiales mecánicamente flexibles y resistentes para fabricar los sensores de gas flexibles. Además de las pruebas de detección de gas, la resistencia a la flexión de los sensores debe probarse para llamar “flexible” a un sensor. El objetivo principal de esta tesis es fabricar sensores de gas flexibles a través de procesos aditivos utilizando óxidos metálicos como materiales sensibles. Los sensores de gas flexibles se fabricaron utilizando un sustrato polimérico flexible (Kapton). Los diferentes procesos empleados fueron compatibles con la temperatura de la temperatura de funcionamiento del sustrato. Entre las técnicas empleadas están la plantilla, la serigrafía, la inyección de tinta, AA-CVD. Además, se realizaron procesos superficiales para mejorar la adhesión de los óxidos metálicos al sustrato polimérico. La flexibilidad de los sensores se probó realizando una prueba de flexión cíclica.
Gas sensors are used to monitor indoor and outdoor environments. Some common applications are to measure: the level of pollutants in the streets, the gases liberated by industrial and car exhausts, gases in mining, blood alcohol content through the exhaled breath, etc. As the field of application for gas sensors is growing, it becomes necessary to adapt the gas sensors to our daily devices and belongings. This requires mechanically flexible and resistant materials to fabricate the flexible gas sensors. In addition to gas sensing tests, the resistance to bending of the sensors should be tested to call a sensor flexible. The main objective of this thesis is to fabricate flexible gas sensors through additive processes using metal oxides as sensitive materials. The flexible gas sensors were fabricated using a flexible polymeric substrate (Kapton). The different processes employed were compatible with the temperature of the operating temperature of the substrate. Among the techniques employed are stencil, screen-printing, inkjet-printing, AA-CVD. Also, surface processes were performed to improve the adhesion of the metal oxides to the polymeric substrate. The flexibility of the sensors was tested by performing a cyclical bending test.

Recently the techniques of applying microtransducers on the biomedical microsystems, such as Cochlear and artificial retina, have become more and more noticeable and well-developed. Yet the fabrication process of transforming the microtransducers into biocompatible flexible devices has not been well-studied. Therefore, we developed a fabrication technique that could generally apply to various of microtransducers. In this research, a novel fabrication process for making biocompatible flexible integrated circuits is presented. By utilizing lapping, etched, deposition Parylene C, we are able to transform electronic devices and microtransducers into flexible and biocompatible devices. In this work, CMOS transistors were fabricated using 0.18 μm technology on an 8-inch SOI (silicon on insulator) wafer。By the wafer back grinding technique and the repeated Parylene C deposition, we constructed 30μm-thick flexible sandwich structure of CMOS transducers from the original thickness of 700 μm. The implantable flexible CMOS transducers are then measured by a Semiconductor Parameter Analyzer HP4156C. The characteristic curves and threshold voltages are shown to have mere small variation before and after this fabrication technique.
