Texte intégralChabchoub, Emna. « New integrated architectures of sensors interfaces in SOI technology for very high temperature applications ». Thesis, Montpellier, 2018. http://www.theses.fr/2018MONTS056/document.
Texte intégralA high temperature integrated sensor interface is proposed. The sensor interface has a fully differential time domain architecture. This approach offers the advantage of better thermal stability compared to typical analog based architectures. The sensor interface is based on Injections Locked Oscillators (ILO) used as phase shifters. A pair of ILOs converts the sensor output voltage into a phase shift difference which is then digitized using a time to digital converter. The sensor interface output depends only on the ratio of its parameters values rather than their absolute values thus leading to a low temperature dependency. The sensor interface is fabricated using a 0.18µm Partially-Depleted Silicon on Insulator technology (PD-SOI) from XFAB which is chosen for its thermal robustness. Measurements show that the sensor interface achieves a thermal variation of 178ppm/°C over ±60mV input full scale and a thermal variation of 65ppm/°C over ±40mV input full scale over a wide operation temperature range extended from -20°C to 220°C
Clauzel, Huchard Irène. « Développement régional et haute technologie : l'exemple de la moyenne vallée de l'Hudson ». Paris 4, 1990. http://www.theses.fr/1990PA040013.
Texte intégralThrough the examples of the mid-hudson valley and the american high technology centers, this work asks the question of the influence of high technology activities in regional development: are they a key, or one of the keys, of the regional development? how are they created and how do high technology centers grow? this analysis shows that these activities expand in preference in an existing industrial area and it reveals the factors that promote creation and development of high technology centers: men, academic and governmental institutions, entrepreneurial fever, business quality and quality of life. The answer to this question about the influence of high technology activities in development is cautious, because some conditions have to be gathered to fight the perverse effects of heterogoneity and the tendanccy to concentrate these activities. The mid-hudson valley, located south of new york state, at about hundred kilometers from the huge newyorker metropolis, is the starting point and the clew of this thought, since it is a high technology center with 40 000 employes in that sector, nevertheless dominated by one company: ibm. The overall study is completed by detailed analysis of the dominating firm and by an analysis of the relations between the region and the near metropolis. Four original surveys, regarding high technology firms, colleges and universities, high technology centers, financial services, complete the information, collected in bibliography, statistics ans interviews

Texte intégralIn the last twenty years there’s been a dramatic increase in the amount of technogies available for the thoracic surgeon. Robotics and Video Assisted Thoracic Surgery are nowadays essential components of the thoracic surgeon’s technical and cultural baggage. These new technologies have also pushed forward the boundaries of costs thus it becomes necessary to define the appropriateness. Prognostic factors may emerge as key drivers in selecting the correct procedure for each specific patient, in accordance with what is demanded by the so-called “precision medicine”. Our research have pointed out some important prognostic factors that could at some point help to speculate the direction our kind of surgery should tail in order to correctly assign every single patient to the most advantageous procedure.

Texte intégralMan's relationship with his environment seems to evolve following a pattern similar to that of the discoveries of science and technology, which bring about new ways to interact with the world. Now in the age of biotechnology and nanotechnology, of digital networks and new audiovisual media, our capacity to act in the world mutates accordingly. In their practice of new media in order to produce their works, many artists question the complexity of the ecological and technological systems that surround us. When they seem to criticize these technologies or try to create new systemic models, is it not often their way of encouraging us to claim ownership of our very habitats? This dissertation studies the ways in which ecology may be revisited through the use of new media and technologies in contemporary artistic works. Our hypothesis is that a study of the relation between art, the environment(s) where it is displayed and the new media it uses may help us rethink the way we inhabit the world. Tentatively, we suggest the word « ecopoiesis » to qualify the creative processes in which ecology is at stake. The goal is to come up with a notion of the complex and systemic relations that the artists, the works of art and the audience have with their environment

Texte intégralNegli ultimi anni lo sviluppo di nuove tecnologie sta aprendo nuove frontiere nella riabilitazione neuropsicologica. In particolare, l’uso della tecnologia touchscreen, congiunto all’uso di dispositivi mobili, fornisce nuove interessanti opportunità per lo sviluppo di programmi innovativi di riabilitazione. Ad oggi, il panorama di software per la riabilitazione neuropsicologica è ampio, ma di questi strumenti pochi o nessuno sono disponibili in italiano o sono specificatamente pensati per pazienti con deficit cognitivi. Per questo motivo, qualche anno fa ho personalmente sviluppato il primo software per la riabilitazione cognitiva su dispositivo mobile in italiano. Lo scopo di questa tesi è quello di descrivere lo sviluppo e il processo di valutazione d’efficacia di questo software, il “Padua Rehabilitation Tool” (PRT). Inizialmente sarà descritta e analizzata la base concettuale di ogni intervento cognitivo: la plasticità cerebrale. Nella Sezione 1 descriverò uno studio per comprendere la relazione tra la performance in esercizi computerizzati per la riabilitazione e la performance in test standardizzati. Nessuno prima ha indagato il tipo di relazione tra queste due dimensioni di esito di un trattamento che, invece, sono sempre state analizzate separatamente. Risulta fondamentale comprendere se il miglioramento negli esercizi computerizzati usati durante la terapia sia (e in che misura) un predittore del miglioramento nei test standardizzati. Nella Sezione 2 descriverò lo sviluppo del PRT e l’uso di questo software in pazienti con diverse eziologie. Originariamente il software è stato sviluppato per pazienti con demenza e così il principale studio d’efficacia è stato condotto su questa popolazione. Infine, considerando la flessibilità dello strumento e la varietà di esercizi che lo compongono, descriverò l’uso del PRT in diversi casi singoli di pazienti con una storia di trauma cranico, infarto, e in un caso di riabilitazione post-coma.
Loukil, Faiza. « Towards a new data privacy-based approach for IoT ». Thesis, Lyon, 2019. http://www.theses.fr/2019LYSE3044.
Texte intégralThe Internet of Things (IoT) connects and shares data collected from smart devices in several domains, such as smart home, smart grid, and healthcare. According to Cisco, the number of connected devices is expected to reach 500 Billion by 2030. Five hundred zettabytes of data will be produced by tremendous machines and devices. Usually, these collected data are very sensitive and include metadata, such as location, time, and context. Their analysis allows the collector to deduce personal habits, behaviors and preferences of individuals. Besides, these collected data require the collaboration of several parties to be analyzed. Thus, due to the high level of IoT data sensitivity and lack of trust on the involved parties in the IoT environment, the collected data by different IoT devices should not be shared with each other, without enforcing data owner privacy. In fact, IoT data privacy has become a severe challenge nowadays, especially with the increasing legislation pressure. Our research focused on three complementary issues, mainly (i) the definition of a semantic layer designing the privacy requirements in the IoT domain, (ii) the IoT device monitoring and the enforcement of a privacy policy that matches both the data owner's privacy preferences and the data consumer's terms of service, and (iii) the establishment of an end-to-end privacy-preserving solution for IoT data in a decentralized architecture while eliminating the need to trust any involved IoT parties. To address these issues, our work contributes to three axes. First, we proposed a new European Legal compliant ontology for supporting preserving IoT PrivacY, called LIoPY that describes the IoT environment and the privacy requirements defined by privacy legislation and standards. Then, we defined a reasoning process whose goal is generating a privacy policy by matching between the data owner's privacy preferences and the data consumer's terms of service. This privacy policy specifies how the data will be handled once shared with a specific data consumer. In order to ensure this privacy policy enforcement, we introduced an IoT data privacy-preserving framework, called PrivBlockchain, in the second research axis. PrivBlockchain is an end-to-end privacy-preserving framework that involves several parties in the IoT environment for preserving IoT data privacy during the phases of collection, transmission, storage, and processing. The proposed framework relied on, on the one hand, the blockchain technology, thus supporting a decentralized architecture while eliminating the need to trust any involved IoT parties and, on the other hand, the smart contracts, thus supporting a machine-readable and self-enforcing privacy policy whose goal is to preserve the privacy during the whole data lifecycle, covering the collection, transmission, storage and processing phases. Finally, in the third axis, we designed and implemented the proposal in order to prove its feasibility and analyze its performances
Zattoni, Olivier. « Cyberespace et paysage : regards croisés sur la ville et les environnements digitaux ». Thesis, Nice, 2014. http://www.theses.fr/2014NICE2041/document.
Texte intégralThis research focuses on symbolic, artistic and representational issues linked to Web and connected systems, such as mobile phones and tablets. Because the screen, i.e. the monitor, is now considered in its mobility, it has to be perceived as a window opened toward the outside. However, the monitor also sketches a lanscape where cyberespace, beyond its logical nature, has to be combined with a reality that aftermath becomes fragmented and recomposed. This applies to the steps we spread while walking in the street, soon transcribed in data on our smartphone : from a simple walk to a track that edges into the city. In this context, city becomes a kind of text and digital artefacts participate to its rewriting, juxtaposing new maps. As city represents the fragmented and the multiple, cyberspace implies a vision of urbanity where man merges himself with technology in a specific way: virtual worlds, along with videogames, science-fiction litterature and movies bring us back to the cyberpunk movement, and before, with the ’shock’ of cities experienced during the modernity by Georg Simmel and Walter Benjamin. This chaos of senses, space and time which defines modern cities is also typical of a technological power that tends to lead the society. Far from orwellian visions, the current advanded technology, although it appears crossed by political, technological and social matters, has to be situated in the context of cybersensbility. Actually in this era of networks and mature technology stands a new vision of technology that implies new practices, new attempts, and makes the cybersensibility concept tangible, as it is opposed to a passive conception in the use of technologies

Texte intégralSaffon, Maxime. « Development of a new dairy ingredient for the utilization of buttermilk constituents ». Thesis, Université Laval, 2013. http://www.theses.ulaval.ca/2013/30076/30076.pdf.
Texte intégralThe use of buttermilk in food formulation is limited due to the extensive water-holding capacity of its phospholipids. The goal of this project was to develop a new approach for the valorization of buttermilk’s constituents. This by-product is rich in valuable components with promising nutritional, healthy, and functional properties such as the milk fat globule membrane (MFGM) constituents, the phospholipids. The two main processes of production of dairy aggregates have been combined resulting of the intensive heat-denaturation of whey proteins at low pH (4.6) in presence of proteins from buttermilk. First, results showed that it was possible to substitute whey proteins by different levels of buttermilk proteins in the process and that the presence of buttermilk constituents led to the formation of mixed aggregates with new functional properties such as a low water-holding capacity. Results revealed that aggregates are pre-formed during the preparation of the buttermilk concentrates involving whey proteins, casein, and MFGM proteins. Phospholipids are integrated to the aggregates through the MFGM at low temperature (65°C), but seem to directly interact with the proteins at higher temperatures ( 80°C). These pre-formed aggregates from buttermilk can act as aggregation nucleus for the proteins from whey. The types of interactions that occur between the proteins significantly affected the properties of the aggregates such as their water-holding capacity, their size, and the solubility of the powder. Finally, it was possible to use the mixed aggregates in the production of set-type yogurt. Whey:buttermilk aggregates were acting more like a passive than a reactive filler, but some possible interactions with the proteins from the skim milk were observed due to the high concentration of thiol groups of the aggregates before heating. However, the dispersibility of the powder must be strictly controlled. Overall, this project proposed a new approach for the use of buttermilk and allowed a better understanding of the thermal behavior of its constituents.
Gaab, Manuela. « Second generation Trisoxazolines : new polydentate and recyclable dendritic ligands for asymmetric catalysis ». Strasbourg, 2009. https://publication-theses.unistra.fr/public/theses_doctorat/2009/GAAB_Manuela_2009.pdf.
Texte intégralIn this work, directed towards more efficient and broadened applications of tris(oxazolinyl)ethanes (trisoxazolines) in asymmetric Lewis acid catalysis, a library of new stereodirecting polydentate and linker-functionalised ligands was designed. On the basis of a multigramm-scale access to appropriately functionalised α-amino alcoholprecursors, three C1-chiral pentadentate and two C3-symmetric hexadentate trisoxazoline derivatives, incorporating peripheral (thio)ether functions, were synthesised. Conferring greater kinetic persistence to labile metals such as lanthanides, they are assumed to allow efficient applications in stereoselective transformations. Bis- and trisoxazolines containing an alkynyl unit have been covalently attached to carbosilane dendrimers and the general catalytic potential of their CuII-complexes was assessed by studying two benchmark reactions. For both of them, the bisoxazoline-based multisite catalysts displayed superior selectivity and, in particular, catalyst activity. The latter was interpreted as being due to the hindered decoordination of the third oxazoline unit, the key step in the generation of the active catalyst, in the immobilised trisoxazolinecopper complexes. Second generation dendrimer catalysts were immobilised in dialysis membrane bags, allowing to effect catalytic conversions by dipping them into substrate-filled reaction vessels. The bisoxazoline-based catalysts gave good and reproducible results after several recyclings, whereas the performance of the trisoxazoline dendrimers decreased monotonically due to their low activity, which necessitated an increased reaction time for each cycle. This resulted in higher levels of catalyst leaching
Im Rahmen dieser Arbeit wurde, mit dem Ziel Tris(oxazolinyl)ethanderivate (Trisoxazoline) in der asymmetrischen Lewissäure-Katalyse effizienter und breiter anzuwenden, eine Serie neuer polydentater und Linker-funktionalisierter Steuerliganden synthetisiert. Basierend auf einem Zugang zu entsprechend funktionalisierten α-Aminoalkoholvorstufen im Multigramm-Maßstab wurden drei C1-chirale pentadentate und zwei C3-symmetrische hexadentate Trisoxazolinderivate mit peripheren (Thio)etherfunktionen synthetisiert. Diese tragen im Prinzip zur kinetischen Stabilisierung labiler Metalle, z. B. Der Lanthanoiden, bei und ermöglichen so deren effiziente Anwendung in stereoselektiven Reaktionen. Nach der kovalenten Trägerung Alkinyl-funktionalisierter Bis- und Trisoxazoline an Carbosilandenrimeren wurde das katalytische Potential ihrer CuII-Komplexe in zwei Benchmarkreaktionen abgeschätzt. Bisoxazolin-basierte Vielzentrenkatalysatoren erzielten mit beiden Systemen höhere Selektivitäten und insbesondere Aktivitäten als ihre Trisoxazolinanaloga. Dies wurde auf die gehinderte Dekoordination des dritten Oxazolins, dem Schlüsselschritt bei der Ausbildung des aktiven Katalysators im Falle der immobilisierten Trisoxazolin-Kupferkomplexe, zurückgeführt. Dendritische Katalysatoren der zweiten Generation wurden in einer Dialysemembran immobilisiert, um durch Eintauchen der resultierenden Beutel in mit Substrat befüllte Reaktionsgefäße katalytische Umsetzungen durchzuführen. Dabei erzielten die Bisoxazolinbasierten Katalysatoren über mehrere Läufe gute, reproduzierbare Werte, während jene der Trisoxazolindendrimere monoton abnahmen. Dies ließ sich auf ihre geringe Aktivität, die damit verbundenen längeren Reaktionszeiten und die erhöhten Katalysatorverluste durch Leaching zurückführen

Texte intégralCell heterogeneity and fluctuant genetic expression in specific microenvironments remain poorly understood. Thus, to address a beginning of answer to all of these general questions, a lot of new scientific paradigms were developed and enable to push the limits of the possible. Thus, the goal of this first thesis project was to develop a highly innovative method for multiplexed epigenetic analysis of cells at a single cell resolution. By linking the Tn5 transposon protein with antibodies targeting key epigenetic factors, it could be possible to identify the binding site of specific transcription factors at a genome wide level. Nevertheless, due to the relative competition to develop a new technology in the field, this very promising tool has been patented by another company, thus the decision was taken to abort this project and focus on another one. A lot of progress and discovery in Biology is strongly correlated with new methodologies that provide the ability to define cell fate at molecular level, but a large majority of them require the use of destructive procedures. For these reasons, the second research project was to develop a new technology allowing transcriptomic analysis over time without any cell destruction. Named TRACE for “TRanslatomic” Analysis Captured in Extracellular vesicles, it is characterized by a cell-type specific transgene expression providing a translation of a representative part of the cell transcriptome inside Extracellular vesicles. Thus, “Translatome” of cells which express TRACE can be followed over time by non-destructive manner in vitro as well as in vivo, which is a powerful tool for many fields of fundamental and translational research

Texte intégralA cryptographic device does not act as a strong-box: its internal activity emanates on media such as power consumption or execution time. Eavesdropping on electro-magnetic radiations is a real threat. Indeed, combining this indirect information with classical cryptanalysis makes confidential information available. Designers cannot turn a bind eye to this vulnerability: cryptographic applications are everywhere in our whole digital world. This thesis focuses on the radiations emitted by electronic devices. We show that the moment and the place where the logic leaks can be estimated precisely, even when designers add countermeasures on the ubiquitous clock signal. These techniques of localization in time and space have been tested with success some targets implementation different algorithms (DES, AES or RSA). The techniques developed enable to find out secrets even when countermeasures are implemented. We have attack asymmetric cryptography (RSA and Elliptic Curves Cryptography) protected with private exponent randomization. Then is targeted the key derivation process based on hash function (SHA1) for symmetric cryptography. These countermeasures are well controlled and low cost. For both of them, we are able first to localize (space and time) a secret dependent object. Then, tailoring classical cryptanalysis enables us to find secrets out. We also have been interested in two confidential symmetric ciphers. Linear Feedback Shift Registers in a Stream Cipher and a generic Feistel scheme are targeted with success. Countermeasures for slowing down attacks have been proposed and discussed

Texte intégralThis study concerns a new CO2 concentration technology integrated into the cement plant. This technology consists in the raw mix decarbonation, induced by its contact with a solid medium in charge of the heat transfer, in an innovative process leading to the emission of pure CO2 at high temperature. This pure gas may be stored underground or used as chemical reactant. This work consists in the study of the decarbonation reaction of the raw mix in operating conditions that are similar to the ones of the new industrial unit. First, the decarbonation kinetics is studied by thermogravimetric analysis on pure CaCO3 powder samples. CaCO3 is the main component of the raw mix. The results led to a better comprehension of the phenomena driving the reaction kinetics and to the determination of kinetic laws in good agreement with the data obtained between 600 °C and 930 °C, and for a partial pressure of CO2 between 0 atm and 1 atm. Then, the interactions between the CaCO3 and the other solids in an industrial raw mix, occurring during its calcination in pure CO2 atmosphere, are studied kinetically (TGA), thermodynamically (simulations) and morphologically (XRD and in situ XRD). Eventually, an experimental device working at high temperatures was built for this study in order to simulate the decarbonation reaction of the raw mix and its elutriation in the real process. This device allows calcining the raw mix in a fluidized bed of media (clinker or olivine). The influences of the fluidized bed temperature, the fluidizing gas velocity, the solid feed rate and the fluidizing gas composition (pure CO2 or air/CO2 mixes) on the hydrodynamic phenomena (elutriation, accumulation, residence time …) , the raw mix-media interactions and the conversion degree are studied

Texte intégralIn this work, highly hydrophobic low density polyethylene (LDPE) hollow fiber membranes aiming to be used for CO2 capture in gas-liquid membrane contactors (GLMC) were fabricated using a simple, novel method, without solvent or diluents, economic and environmentally friendly, which does not require any mechanical or thermal post-treatments. In order to produce hollow fibers and control their porosity, the process combines melt extrusion and template-leaching techniques. A mixture of LDPE and NaCl particles first produce blends with different salt contents. A microporous structure and a rough highly hydrophobic surface can then be produced by leaching the salt particles from the hollow fiber matrix via immersion in water. The new method represents a very promising alternative to conventional membrane fabrication approaches which are mainly based on phase inversion process that involves toxic and expensive solvents. The fabricated membranes were characterized in terms of morphology, density, porosity and pore size distribution, hydrophobicity, breakthrough pressure and mechanical properties. Since the phenomenon of membrane wetting by liquid absorbents is the major cause of the reduction of long-term efficiency of GLMC, a comprehensive study on the compatibility between membrane and absorbent liquid was performed. Morphological, chemical and thermal stability of LDPE membranes in contact with different aqueous alkanolamine solutions including monoethanolamine (MEA) and 2-amino-2-hydroxymethyl-1,3-propanediol (AHPD), as well as blends of MEA/PZ (piperazine) and AHPD/PZ, was investigated in detail.

Texte intégralLakkis, Sari. « New Gas Sensor for Exhaust Emissions of Internal Combustion Engines ». Thesis, Versailles-St Quentin en Yvelines, 2014. http://www.theses.fr/2014VERS0064/document.
Texte intégralGases represent one of the most important key measurands in many industrial and domestic activities. The need to detect single gas or a group of gases at the same time varies from one application to another. One of the most important applications of gas sensing is in the concentration measurement of exhaust emissions in internal combustion engines. The variety of gases emitted by these engines and the necessity for a precise measurement of their concentrations are the major incentives for researchers to develop gas sensors that are not only limited to a certain type of gases but to a variety of gases. The most interest gases include CO, NO, NO2, NH4, SO2, CO2, CH4 and other hydrocarbons. These gases can be harmful to human health if present beyond a certain concentration. The analysis of exhaust emissions of internal combustion engines has traditionally been achieved in laboratories using bulk gas analyzers and costly equipments. In order to create a system which can do the work of these analyzers, a sensor that can measure the concentration of multiple gases at the same time is needed. Instead of using a sensor for each gas which is costly and introduce another complexity to the analysis procedure due to the different technologies that are used in the detection of different types of gases. This directly translates into loss of financial and human resources that could otherwise be productively used. In an effort to remedy this situation, this dissertation proposes an alternate approach that uses one sensor to analyze multiple gases simultaneously. This has a significant potential in reducing the aforementioned complexity, size and data collection tasks, and at the same time can lower the cost of the overall system.This dissertation presents the design, methodology, and development of a new method for gas concentration measurement using digital image processing through modeling the color mixing of light emissions in gas discharge tube. The application of the inverse model allows us to get the percentages of each gas in a mixture of up to four gases knowing already the color of emission of the whole mixture and the color of emission of each gas alone. It also discusses the miniaturization potential of some of the methods that are promising in the ability of their miniaturization but suffer from different problems. A comparison is also done among the miniaturized sensors in terms of different parameters like sensitivity, selectivity, cost and other terms. In achieving the research objectives, major technical challenges such as color mixing modeling, imaging sensor calibration, and measurements’ error handling have been successfully identified and addressed

Texte intégralThe main part of optical fibers used in the fields of optical sources and sensors are called 'functionalised', i.e. they have new properties, due to their nature and/or structure, compared to standard fibers. To do this, we will use 'Powder' technology for the realization of optical fiber using properties of original vitreous glasses developed during this thesis. Three families of optical fibers will be studied in order to demonstrate the great potential of this association, materials - technology. The first exploit the structuring of the cladding with two vitreous glass rods (Panda type) doped or not with copper oxide. The study of this fiber is done from the synthesis of the material up to the test of this fiber as a sensor. The second fiber leads us to design a novel optical glass matrix, to define the optimal composition and decline form of an optical fiber including the glass for the core. Finally, the optical fiber manufacturing process is used to produce optical fiber with glass-ceramic core, i.e. starting from a vitreous matrix specially developed for this application happen to grow the nano-structures in the core of the fiber and obtain a novel fiber family

Texte intégralThis thesis addresses and analyzes the legal implications of international law arising from the increasing use of self-navigating ships. This technological innovation poses particular criticalities concerning the current absence of ad hoc provisions and the difficulty of applying the pre-existing rules concerning international navigation. The thesis is structured in three chapters, each of which deals with the analysis of an area of international law particularly problematized by the use of autonomous ships. The first chapter will look at whether and how the rules on safety of navigation apply to autonomous ships. The second chapter investigates the possibility of extending the rules apportioning states' jurisdictional powers to the use of self-driving ships. The third chapter observes what critical issues arise from the use of these new vessels with respect to international norms aimed at rescuing people "in distress." Finally, the last pages of the thesis report some final reflections aimed at framing the legal analysis carried out in a more general perspective, trying to understand what steps should be taken by the international community in order to cope with the critical issues arising from the construction and use of autonomous ships.

Texte intégralThis dissertation is a multi-perspective inquiry into the phenomenon of social media use in organizational context. It focuses on the processes of enactment of this new technology and investigates how these developments are embedded in the context of occupational norms, social roles, organizational control and autonomy. The research setting is based on the 19-month social media implementation campaign by a central European media organization as a means of enhancing communication and coordination within the organization. The implementation encompassed two departments, journalists and advertising agents, who were asked to create and open their online social media profiles and befriend their colleagues. The dissertation comprises four research papers each taking a separate perspective on the phenomenon. Methodologically, the dissertation builds on qualitative case-study approach and abductive and inductive reasonings. The thesis provides theoretical and practical contributions to the understanding normative prerequisites, process and consequences of social media use in organizational context for occupational norms, online knowledge collaboration and organizational control while presenting co-evolution of the technology meaning and use

Non-invasive neural stimulation techniques are of increasing importance as devices move from the lab to the clinical environment. One such technology-transcranial magnetic stimulation-has already made the transition and is currently used by clinicians to treat depression. This device has several drawbacks, such as a limited ability to focus its energy to a relatively small region and to distribute energy to deep structures. This thesis simulates an inhomogeneous human brain under transcranial magnetic stimulation. The models developed indicate that regions of high conductivity and permittivity may be the key to overcoming the limitations of current TMS technology. Specifically, models of 1mm-sized particles of high conductivity and permittivity increased the induced current in deep regions by a factor of 600,000, indicating that some modification to the delivery method of TMS may drastically increase its effectiveness and usability. Unlike other forms of stimulation, acoustic energy has not been explored in great depth in relation to neural stimulation. This thesis explores the possibility of using ultrasound to focally target and non-invasively stimulate rodents in vivo. While the mechanism by which ultrasound works to alter neural activity is difficult to pinpoint, in vivo testing with a variety of ultrasound frequencies, powers, and delivery protocols may lead to a breakthrough in the field. Furthermore, this thesis outlines a method for stimulating neural activity with ultrasound by way of heating specific regions.

Lieval, Cecile. « Innovation technologique et risques insaisissables : une territorialisation impossible ? » Thesis, Grenoble, 2013. http://www.theses.fr/2013GRENH034.
Texte intégralSince the 2000's, the development of nanotechnologies gives rise to oppositions in connection with "new risks" that are only just starting to be defined, together with an ethical questioning, which doesn't prevent the worldwide development of those technologies, in the form of localized poles subject to harsh requirements of competitiveness. Now, those territorial development projects generate conflicts about risks which are difficult to assess on a local scale : what are the consequences on the way the territorial development projects are conducted ? And what about the protest facing elusive risks ? The case of Grenoble allows to study this tension between development projects and a conflict with very local consequences, and the scientific and economic development of those technologies following a worldwide practice. For local actors, how to think out territorial development on a local scale when faced with this radical global uncertainty, in the context of an economical competition that exceeds but compels them ? How is the question of risks and uncertainty, whose "novelty" will have to be questioned, likely to renew or not the process of territorialisation, the control of projetcs, the practices of justification, and the way the actors manage to base anticipation on the rule of reason

Texte intégralThe present Doctoral Thesis aimed to analyze the tribological, corrosion and tribocorrosion behavior of new martensitic stainless steels and their degradation mechanisms for aeronautical applications. For this, electrochemical, tribo-electrochemical and ex-situ surface analysis techniques were used. Wear damage was found to be critically affected by the hardness of the material and its hardening during sliding. Martensitic stainless steels showed higher scratch wear resistance but higher wear material loss when compared to the austenitic stainless steel. Corrosion resistance of martensitic stainless steels is driven by their passivity, whose kinetics can be described through a high field conduction model. Passive dissolution rate depends on the surface chemistry of the material, thus decreasing with the Cr content in the passive film. Degradation mechanisms involved in tribocorrosion of martensitic stainless steels included plastic deformation, shakedown and low-cycle fatigue. The consequences of those involved mechanisms depended on the prevailing electrochemical conditions
La presente Tesis Doctoral tiene como objetivo analizar el comportamiento tribológico, frente a la corrosión y a la tribocorrosión de nuevos aceros inoxidables martensíticos y sus mecanismos de degradación en aplicaciones aeronáuticas. Para ello, se han utilizado técnicas electroquímicas, tribo-electroquímicas y de análisis de superficie ex-situ. El desgaste depende de la dureza del material y de su endurecimiento durante el deslizamiento. Los aceros inoxidables martensíticos mostraron una mayor resistencia al rallado pero una mayor pérdida de material en el ensayo tribológico de desgaste si se compara con el acero inoxidable austenítico. La resistencia a la corrosión de los aceros inoxidables martensíticos es promovida por su pasividad, cuya cinética puede ser descrita a través de un modelo de tipo high field. La velocidad de disolución pasiva depende de la química de la superficie del material, disminuyendo por lo tanto con el contenido de Cr en la película pasiva. Los mecanismos de degradación en tribocorrosión de los aceros inoxidables martensíticos incluyen deformación plástica, shakedown y fatiga de bajo ciclo. Las consecuencias de esos mecanismos dependen de las condiciones electroquímicas del sistema

Texte intégralSouth Africans were deprived of numerous forms of freedom of expression during the prolonged apartheid era. Very few South Africans were able to participate in international events and interact with the outside world and institutions that promoted freedom were banned. Attempts to initiate freedom were suppressed by the ruling government. Nevertheless, in the era of transformation and democracy, during the post-apartheid regime, feelings of hope of transparency, especially in the media, were ushered in. The expectation and hope of a totally free democracy was further heightened by the implementation of the Bill of Rights. Freedom of expression in South Africa was soon threatened and came under strain when the government began making plans to introduce a secrecy bill to contain its covert operations. Numerous community organisations are desperately lobbying to suppress government’s initiative to formalise the secrecy bill. Government, on the other hand, seems to be forging ahead to anoint their Currently, the media goes through a government censorship where the government is vigorously trying to pass the Protection of Information Bill in order to guard government information and its ‘corrupt activities’. If passed, incriminating information will be protected under this Bill. The new and democratically elected South African government which is characterized by ‘freedom of speech and free access of information’ threatens media freedom and juxtaposes what the former President Nelson Mandela stood for: “A critical, independent and investigative press is the lifeblood of any democracy”. The study discusses the relationship between the use of new technologies and the State Protection of the Information Bill. It also examines how these new technologies, through social interaction and citizen journalism, may eradicate ‘corrupt activities’ performed by the government that are camouflaged as ‘classified’ information to ascertain democracy, freedom of speech and access to information.
Prendes, Jorge. « New statistical modeling of multi-sensor images with application to change detection ». Thesis, Université Paris-Saclay (ComUE), 2015. http://www.theses.fr/2015SACLC006/document.
Texte intégralRemote sensing images are images of the Earth surface acquired from satellites or air-borne equipment. These images are becoming widely available nowadays and its sensor technology is evolving fast. Classical sensors are improving in terms of resolution and noise level, while new kinds of sensors are proving to be useful. Multispectral image sensors are standard nowadays and synthetic aperture radar (SAR) images are very popular.The availability of different kind of sensors is very advantageous since it allows us to capture a wide variety of properties of the objects contained in a scene. These properties can be exploited to extract richer information about these objects. One of the main applications of remote sensing images is the detection of changes in multitemporal datasets (images of the same area acquired at different times). Change detection for images acquired by homogeneous sensors has been of interest for a long time. However the wide range of different sensors found in remote sensing makes the detection of changes in images acquired by heterogeneous sensors an interesting challenge.Accurate change detectors adapted to heterogeneous sensors are needed for the management of natural disasters. Databases of optical images are readily available for an extensive catalog of locations, but, good climate conditions and daylight are required to capture them. On the other hand, SAR images can be quickly captured, regardless of the weather conditions or the daytime. For these reasons, optical and SAR images are of specific interest for tracking natural disasters, by detecting the changes before and after the event.The main interest of this thesis is to study statistical approaches to detect changes in images acquired by heterogeneous sensors. Chapter 1 presents an introduction to remote sensing images. It also briefly reviews the different change detection methods proposed in the literature. Additionally, this chapter presents the motivation to detect changes between heterogeneous sensors and its difficulties.Chapter 2 studies the statistical properties of co-registered images in the absence of change, in particular for optical and SAR images. In this chapter a finite mixture model is proposed to describe the statistics of these images. The performance of classical statistical change detection methods is also studied by taking into account the proposed statistical model. In several situations it is found that these classical methods fail for change detection.Chapter 3 studies the properties of the parameters associated with the proposed statistical mixture model. We assume that the model parameters belong to a manifold in the absence of change, which is then used to construct a new similarity measure overcoming the limitations of classic statistical approaches. Furthermore, an approach to estimate the proposed similarity measure is described. Finally, the proposed change detection strategy is validated on synthetic images and compared with previous strategies.Chapter 4 studies Bayesian non parametric algorithm to improve the estimation of the proposed similarity measure. This algorithm is based on a Chinese restaurant process and a Markov random field taking advantage of the spatial correlations between adjacent pixels of the image. This chapter also defines a new Jeffreys prior for the concentration parameter of this Chinese restaurant process. The estimation of the different model parameters is conducted using a collapsed Gibbs sampler. The proposed strategy is validated on synthetic images and compared with the previously proposed strategy. Finally, Chapter 5 is dedicated to the validation of the proposed change detection framework on real datasets, where encouraging results are obtained in all cases. Including the Bayesian non parametric model into the change detection strategy improves change detection performance at the expenses of an increased computational cost
