▼ The purpose of this thesis is to explore and understand the ‘localisation’ phenomenon from a geographical, cultural, technical and governmental theme to help explain why the level of local content in the oil and gas engineering and technical services private sector tends to flatten out at specific engineering and management skillsets in order to balance quality and delivery of the service and maintain operational excellence. Five research objectives were developed to achieve the research aim to provide a clear understanding, from a corporate strategic perspective, of the drivers and perceived barriers to successful localisation. For the purposes of this thesis, the term "localisation" is understood to mean “when a local national is filling a required job sufficiently competently to fulfil organisational needs” (Potter 1989). Due to the nature of investigation, this study adopted a qualitative inquiry. Thus, a mix of qualitative data collection methods were used such as document, experienced observation, and interviews with senior managers at the corporate strategic level of the business. An interview guide was developed from a conceptual framework generated from the literature review. The study targeted an ‘elite’ sample of oil and gas executives/ managers who are considered role models in the case study organisation. This study argues that a form of grounded theory/qualitative inquiry is adopted during data analysis using open, axial, and selective coding, leading to an evolved conceptual framework of localisation drivers and barriers. In addition to a thematic analysis, an integrated view from the researcher as an experienced observer resulted in a validated conceptual framework. This framework provides a holistic set of factors that must be considered, and understood, from a corporate strategic perspective as being directly influential in achieving successful localisation of a subsidiary part of the business. It is found that four of the five objectives were met and objective five partially achieved which identified an opportunity for further research to investigate and develop weightings across the four localisation barrier themes to determine an optimised balance of cost, delivery, and local content to maintain the desired operational excellence in the oil and gas services contractor industry. The study appears to have a contribution to knowledge through the evolving conceptual framework of localisation and provides the first holistic view of both localisation drivers and barriers relevant to oil and gas services contractors. A methodological contribution is worth noting since the researcher acted as an experienced observer during the process of this research. No doubt, industrial experience of the research and his access to the senior management has been one of the key contributing factors to a successful completion of the study. Finally, one can argue that this study has made contribution to the policy makers who provided access to the researcher. The findings of this study will provide a better and clear…

Cette thèse présente des résultats théoriques sur le chaos dans les systèmes quantiques. Dans sa première partie, nous étudions la dynamique du rotateur pulsé. Ce système, qui est la référence pour l'étude du chaos quantique, présente un gel de la diffusion en impulsion, appelé localisation dynamique. Celle-ci est un phénomène purement quantique basé sur des interférences destructives. Comme tout phénomène d'interférence, la localisation dynamique est affectée par l'émission spontanée. Dans cette thèse, nous proposons une méthode basée sur la spectroscopie Raman, pour limiter l'impact de l'émission spontanée. Nous menons une étude analytique complète de la dynamique, en très bon accord avec nos simulations numériques. Du fait de sa périodicité temporelle, le rotateur pulsé présente aussi des résonances quantiques, qui sont l'analogue de l'effet Talbot optique. En décrivant ces résonances dans l'espace des positions, nous en donnons une image simple et intuitive, basée sur des notions classiques comme la force. Les condensats de Bose-Einstein ont ouvert la voie à l'obtention de phénomènes quantiques nouveaux. La non-linéarité de leur équation d'évolution permet notamment l'observation du chaos quasi-classique. Nous proposons ici une méthode pour le détecter, basée sur la mesure de la position moyenne du condensat. Cette méthode, dont la validité est confirmée par les exposants de Lyapunov du système, permet de distinguer sans équivoque les trajectoires chaotiques et régulières.

This thesis contains theoretical results about chaos in quantum systems. ln its first part, we study the dynamics of the quantum kicked rotor. This system, which is paradigmatic of quantum chaos, exhibits dynamical localization, a decay of diffusion in momentum space. The latter is a purely quantum phenomenon, as it is based on destructive interferences. As aIl interference effects, dynamical localization is affected by spontaneous emission. ln this manuscript, we propose a method to decrease the effect of spontaneous emission, by using Raman spectroscopy. We perform a full analytical study in very good agreement with our numerical simulations. As a consequence ofits temporal periodicity, the kicked rotor also exhibits quantum resonances, the analogy of the optical Talbot effect. By describing them in position space, we provide a simple and intuitive image of the resonances, based on classical notions like force. Bose-Einstein has enabled the study ofunprecedented quantum phenomena. ln particular, the nonlinearity of their evolution equation has made possible the observation of quasi-classical chaos. Here, we propose a method to detect chaos, by measuring the averaged position of the condensate. This method enables us to clearly distinguish chaotic and regular trajectories. Its validity is confirmed by the calculation of the system Lyapunov exponents.

▼ Pompe disease is a progressive form of muscular dystrophy caused by a deficiency in the lysosomal enzyme α-glucosidase (GAA). GAA catabolises glycogen and its deficiency leads to glycogen accumulation in the vesicular network of affected cells. Multiple therapies exist to treat Pompe disease but these are not completely effective (Winkel et al., 2003), necessitating the development of new therapeutic strategies. A number of enzymes that reside outside of the lysosome, either in the cytoplasm (Watanabe et al., 2008) or in circulation (Ugorski et al., 1983), can catabolise glycogen. It was postulated that if vesicular glycogen in Pompe cells was transferred out of these compartments it could then be alternatively degraded. The ability to remove vesicular glycogen from Pompe cells may reduce the onset/progression of the disorder, providing a therapeutic option for patients. Exocytosis is a ubiquitous cellular mechanism where intracellular vesicles fuse with the cell surface and permit vesicle content to be released from the cell. It was postulated that exocytosis may provide a mechanism to release accumulated glycogen from Pompe cells. Approximately 4% of vesicular glycogen was exocytosed from Pompe skin fibroblasts after 2 hrs in culture. Pompe cells exocytosed 2.7-fold more glycogen than unaffected cells. A cellular mechanism was therefore identified that had the capacity to release glycogen from Pompe cells. Culture conditions can alter the amount of exocytosis in fibroblasts (Martinez et al., 2000). In this study the effect of cell confluence and components of the culture media on lysosomal exocytosis was examined in Pompe skin fibroblasts. Increasing the extracellular concentration of Ca²⁺ led to a 1.4-fold increase in glycogen release compared to cells cultured in standard media conditions. Culture confluence had a key influence on glycogen exocytosis, with sub-confluent Pompe cells releasing >80% of glycogen after 2 hrs in culture, 35-fold higher than confluent cells. Exocytic mechanisms therefore exist that allow up-regulation of glycogen exocytosis in Pompe skin fibroblasts. A number of pharmacological compounds induce exocytosis in cultured cells (Amatore et al., 2006). Pompe skin fibroblasts treated with three compounds; calcimycin, lysophosphatidylcholine and α-L-iduronidase, each demonstrated a ≥ 1.5-fold increase in glycogen exocytosis, when compared to untreated Pompe controls. Calcimycin was the most effective compound for inducing glycogen exocytosis, with 12% released after 2 hrs of treatment, but confluent Pompe cells released less than that observed from sub-confluent Pompe cells. This difference in glycogen release may have resulted from the induction of different exocytic mechanisms. Complete exocytosis, where the vesicle completely fuses with the cell surface and releases all vesicle content, is induced in sub-confluent Pompe cells. In contrast, cavicapture, involving only a partial pore opening and limited vesicle content release, is induced in response to calcimycin treatment.

▼ To utilise multiple robots, it is fundamental to know what they should do, called task allocation, and to know where the robots are, called localisation. The order that tasks are completed in is often important, and makes task allocation difficult to solve (40 tasks have 1047 different ways of completing them). Algorithms in literature range from fast methods that provide reasonable allocations, to slower methods that can provide optimal allocations. These algorithms work well for systems with identical robots, but do not utilise robot differences for superior allocations when robots are non-identical. They also can not be applied to robots that can use different tools, where they must consider which tools to use for each task. Robot localisation is performed using sensors which are often assumed to always be available. This is not the case in GPS-denied environments such as tunnels, or on long-range missions where replacement sensors are not readily available. A promising method to overcome this is collaborative localisation, where robots observe one another to improve their location estimates. There has been little research on what robot properties make collaborative localisation most effective, or how to tune systems to make it as accurate as possible. Most task allocation algorithms do not consider localisation as part of the allocation process. If task allocation algorithms limited inter-robot distance, collaborative localisation can be performed during task completion. Such an algorithm could equally be used to ensure robots are within communication distance, and to quickly detect when a robot fails. While some algorithms for this exist in literature, they provide a weak guarantee of inter-robot distance, which is undesirable when applied to real robots. The aim of this thesis is to improve upon task allocation algorithms by increasing task allocation speed and efficiency, and supporting robot tool changes. Collaborative localisation parameters are analysed, and a task allocation algorithm that enables collaborative localisation on real robots is developed. This thesis includes a compendium of journal articles written by the author. The four articles forming the main body of the thesis discuss the multi-robot task allocation and localisation research during the author’s candidature. Two appendices are included, representing conference articles written by the author that directly relate to the thesis.

Research Doctorate - Doctor of Philosophy (PhD)

The objective of this research work is to advance the process of integrating mobile service robots in public environments. With the growth in use of service robots in the complex world of humans, they are required to sustain long-term autonomy while possessing natural scene understanding capability. Robotics researchers have devised robust mechanisms to impart the capacity for localisation/way finding and navigation to these robots. However, the smooth integration of such service robots into existing industry, healthcare and warehousing environments is yet to be seen. Often, the addition of a robot worker requires additional infrastructure to support the robot’s way-finding process. As a result, these robots are restricted to certain fixed parts of the building where the infrastructure has been installed. An example of such a service robot is the Swisslog Telelift commissioned at the Royal North Shore Hospital, Sydney. The service robot is an Automated Ground Vehicle that has been commissioned to transport food, linen and supplies across various departments of the hospital. This thesis contributes towards enabling a smoother integration of such service robots, and reconditioning their way-finding capacity to support long-term autonomy. The enhancement is specifically focused towards minimising the requirements for additional markers and beacons that act as artificial landmarks to help in the task of localisation. This is achieved by developing methods of automatically identifying salient locations - landmarks - based on their 3D structure, presence of salient objects, and by estimating a measure of surprise encountered on experiencing the location. A methodology for evaluating a 3D model of a building for the presence of landmarks is proposed. 3D isovists are employed to perceive the structure of the environment, which is then processed further to extract the gist of the entire structure. The statistical summaries extracted from these 3D isovists are compared and analysed to identify those that are different from others within a small neighbourhood (local saliency), and throughout the entire building (global saliency). The developed method is converted into an empirical methodology involving extraction of the 3D isovists from a simulated walk-through experience of a 3D model of the corresponding building. Hypothetical architectural models of two canonical house designs: the Villa Savoye at Poissy (near Paris, France) by Le Corbusier and the Dana-Thomas House at Springfield (Illinois, USA) by Frank LloydWright are employed to demonstrate the use of the proposed technique. The methodology serves two purposes: as a tool for evaluation of plans by architects for the presence of structurally variant locations, and as a method to evaluate the structural saliency of a location as detected by a robot. When the structure of the environment is monotonous, humans tend to remember a location by associating it with the presence of any salient object. Aiming to imitate this…

▼ Sensors employing mode localisation in weakly coupled resonators have been increasingly viewed as an alternative to resonant frequency shift based sensing. Much theory has been proposed highlighting the advantages of these sensors including the increased sensitivity and the promise of common mode rejection to first order environmental variations. This has led to the development of proof-of-concept sensors to sense physical quantities such as displacement, charge, mass, and acceleration. However, practical aspects of developing a sensor starting from design of a closed-loop implementation to understanding different operating regions with the aim of resolution analysis and noise optimisation have yet to be explored in depth. This work delves into these practical aspects of developing ultra-high resolution mode-localised MEMS sensors. First, the mechanical sensor is integrated with a prototype closed-loop oscillator along with the interface electronics on a printed circuit board. Key aspects of sensors such as stability, noise floor, and bandwidth are analysed using this integrated sensor system. A critical observation is made on the improvement of stability of the amplitude ratio output metric over its frequency shift counterpart at large integration times therefore, highlighting the advantage of common mode rejection to environmental factors. The common mode rejection abilities of both mechanically and electrically coupled devices are next studied at different operating regions. These are then compared to the state-of-the-art differential frequency measurements. Amplitude ratio measurements in an electrically coupled device showed an order of magnitude better rejection to temperature variations over a mechanically coupled device. Furthermore, amplitude ratio measurements in the electrically coupled device were on par with the rejection offered by the differential frequency output in the same device. This result highlights the advantage of amplitude ratio measurements that are able to achieve the same common mode rejection with the help of a single oscillator instead of the two oscillators required in differential frequency output measurements. The resolution of the mode-localised sensor is then explored with the purpose of optimising operating regions to achieve the best noise figure. A detailed theoretical analysis is first undertaken to optimise the amplitude ratio noise in different noise dominant regimes. It is predicted that the resonator-based noise (such as thermo-mechanical noise) can be optimised be operating at an amplitude ratio of √{2} and the electronic sourced noises can be optimised at an amplitude ratio of √{1.5} in a single ended resonator drive configuration. Additionally, both sources of noise are predicted to decrease with the decrease of the coupling stiffness. This result is then validated using experimental data to verify the claim. A further noise reduction is sought by operating the coupled resonators in the nonlinear domain with interesting observations on the variations of…

▼ Ubiquitous computing systems aim to assist us as we go about our daily lives, whilst at the same time fading into the background so that we do not notice their presence. To do this they need to be able to sense their surroundings and infer context about the state of the world. Location has proven to be an important source of contextual information for such systems. If a device can determine its own location then it can infer its surroundings and adapt accordingly. Of particular interest for many ubiquitous computing systems is the ability to track people in indoor environments. This interest has led to the development of many indoor location systems based on a range of technologies including infra-red light, ultrasound and radio. Unfortunately existing systems that achieve the kind of sub-metre accuracies desired by many location-aware applications require large amounts of infrastructure to be installed into the environment. This thesis investigates an alternative approach to indoor pedestrian tracking that uses on-body inertial sensors rather than relying on fixed infrastructure. It is demonstrated that general purpose inertial navigation algorithms are unsuitable for pedestrian tracking due to the rapid accumulation of errors in the tracked position. In practice it is necessary to frequently correct such algorithms using additional measurements or constraints. An extended Kalman filter is developed for this purpose and is applied to track pedestrians using foot-mounted inertial sensors. By detecting when the foot is stationary and applying zero velocity corrections a pedestrian’s relative movements can be tracked far more accurately than is possible using uncorrected inertial navigation. Having developed an effective means of calculating a pedestrian’s relative movements, a localisation filter is developed that combines relative movement measurements with environmental constraints derived from a map of the environment. By enforcing constraints such as impassable walls and floors the filter is able to narrow down the absolute position of a pedestrian as they move through an indoor environment. Once the user’s position has been uniquely determined the same filter is demonstrated to track the user’s absolute position to sub-metre accuracy. The localisation filter in its simplest form is computationally expensive. Furthermore symmetry exhibited by the environment may delay or prevent the filter from determining the user’s position. The final part of this thesis describes the concept of assisted localisation, in which additional measurements are used to solve both of these problems. The use of sparsely deployed WiFi access points is discussed in detail. The thesis concludes that inertial sensors can be used to track pedestrians in indoor environments. Such an approach is suited to cases in which it is impossible or impractical to install large amounts of fixed infrastructure into the environment in advance.

La mitochondrie et le plaste sont des organites essentiels au sein de la cellule végétale. Les processus du métabolisme de l’ARN tels que la transcription, les modifications post-transcriptionnelles d'épissage et d’édition et la traduction des organites sont très similaires. Parmi les acteurs de ces processus, les protéines PentatricoPeptide Repeat (PPR) ont un rôle prépondérant. Dans ce travail de recherche, j’ai évalué, dans un premier temps, la double localisation des protéines PPR vers la mitochondrie et le chloroplaste chez Arabidopsis thaliana. La synthèse de l’ensemble des données ont permis d’établir que sur les 473 membres de la famille PPR chez A. thaliana, 9% ont une potentielle double localisation dans les deux organites. Un partie de ce travail de thèse, analyse et discute les implications évolutives et fonctionnelles au sein de cette classe de localisation. Afin de comprendre l’activité des protéines PPR dans les deux organites, j’ai focalisé mes analyses fonctionnelles sur quatre protéines PPR (OTP90, OTP91, OTP100 et DYW2) potentiellement impliquées dans le phénomène d’édition. Dans ce travail de thèse, j’ai pu mettre en évidence que les protéines OTP90 et DYW2 agissent sur l’édition des transcrits des organites et particulièrement que la protéine DYW2 participe dans l’édition des transcrits chloroplastiques comme aussi sur des transcrits mitochondriaux. Ainsi, les résultats de mon travail de recherche s’ajoutent aux récentes données, obtenues de par le monde, montrant que les protéines PPR peuvent avoir de rôles complexes bien influençant à la fois divers transcrits et/ou processus dans le métabolisme de l’ARN des organites.

Mitochondrial and plastid are essential organelles within the plant cell. The process of RNA metabolism such as transcription, post-transcriptional modifications as splicing and editing and translation are very similar in these organelles. Among the actors of these processes, the PentatricoPeptide Repeat (PPR) proteins have an important role. In this research, firstly, I assessed the dual localisation of PPR proteins to mitochondria and chloroplasts organelles in Arabidopsis thaliana. The synthesis of all the data, those produced during my thesis, those available in the literature and those contained in the proteomic databases have revealed that between the 473 members of the PPR family in A. thaliana, 9 % are potentially dually localaized in both organelles. A part of this thesis analyzes and discusses the evolutionary and functional implications of this class of localisation in the PPR family. In order to understand the activity of PPR proteins in both organelles, I focused my work in the functional analysis on four PPR proteins (OTP90, OTP91, OTP100 and DYW2 ) potentially involved in the editing process. Although functional characterization of these four proteins has not been fully completed, in this thesis, I was able to demonstrate that the OTP90 and DYW2 proteins act on editing of organelles transcripts and particularly I found that the DYW2 protein participates in the…

▼ This thesis considers the domain of acoustic source localisation and tracking in an indoor environment. Acoustic tracking has applications in security, human-computer interaction, and the diarisation of meetings. Source localisation and tracking is typically a computationally expensive task, making it hard to process on-line, especially as the number of speakers to track increases. Much of the literature considers single-source localisation, however a practical system must be able to cope with multiple speakers, possibly active simultaneously, without knowing beforehand how many speakers are present. Techniques are explored for reducing the computational requirements of an acoustic localisation system. Techniques to localise and track multiple active sources are also explored, and developed to be more computationally efficient than the current state of the art algorithms, whilst being able to track more speakers. The first contribution is the modification of a recent single-speaker source localisation technique, which improves the localisation speed. This is achieved by formalising the implicit assumption by the modified algorithm that speaker height is uniformly distributed on the vertical axis. Estimating height information effectively reduces the search space where speakers have previously been detected, but who may have moved over the horizontal-plane, and are unlikely to have significantly changed height. This is developed to allow multiple non-simultaneously active sources to be located. This is applicable when the system is given information from a secondary source such as a set of cameras allowing the efficient identification of active speakers rather than just the locations of people in the environment. The next contribution of the thesis is the application of a particle swarm technique to significantly further decrease the computational cost of localising a single source in an indoor environment, compared the state of the art. Several variants of the particle swarm technique are explored, including novel variants designed specifically for localising acoustic sources. Each method is characterised in terms of its computational complexity as well as the average localisation error. The techniques’ responses to acoustic noise are also considered, and they are found to be robust. A further contribution is made by using multi-optima swarm techniques to localise multiple simultaneously active sources. This makes use of techniques which extend the single-source particle swarm techniques to finding multiple optima of the acoustic objective function. Several techniques are investigated and their performance in terms of localisation accuracy and computational complexity is characterised. Consideration is also given to how these metrics change when an increasing number of active speakers are to be localised. Finally, the application of the multi-optima localisation methods as an input to a multi-target tracking system is presented. Tracking multiple speakers is a more complex task than tracking single acoustic source,…

▼ Radio frequency (RF) source localisation is a critical technology in numerous location-based military and civilian applications. In this thesis, the problem of RF source localisation has been studied from the perspective of the system implementation for real-world applications. Commercial off-the-shelf Software Defined Radio (SDR) devices are used to demonstrate the practical RF source localisation systems. Compared to the conventional localisation systems, which rely on dedicated hardware, the SDR-based system is developed using general-purpose hardware and software-defined components, offering great flexibility and cost efficiency in system design and implementation. In this thesis, the theoretical results of source localisation are evaluated and put into practice. To be specific, the practical localisation systems using different measurement techniques, including received-signal-strength-indication (RSSI) measurements, time-difference-of-arrival (TDOA) measurements and joint TDOA and frequency-difference-of-arrival (FDOA) measurements, are demonstrated to localise the stationary RF signal sources using the SDRs. The RSSI-based localisation system is demonstrated in small indoor and outdoor areas with a range of several metres using the SDR-based transceivers. Furthermore, interests from the defence area motivated us to implement the time-based localisation systems. The TDOA-based source localisation system is implemented using multiple spatially distributed SDRs in a large outdoor area with the sensor-target range of several kilometres. Moreover, they are implemented in a fully passive way without prior knowledge of the signal emitter, so the solutions can be applied in the localisation of non-cooperative signal sources provided that emitters are distant. To further reduce the system cost, and more importantly, to deal with the situation when the deployment of multiple SDRs, due to geographical restrictions, is not feasible, a joint TDOA and FDOA-based localisation system is also demonstrated using only one stationary SDR and one mobile SDR. To improve the localisation accuracy, the methods that can reduce measurement error and obtain accurate location estimates are studied. Firstly, to obtain a better understanding of the measurement error, the error sources that affect the measurement accuracy are systematically analysed from three aspects: the hardware precision, the accuracy of signal processing methods, and the environmental impact. Furthermore, the approaches to reduce the measurement error are proposed and verified in the experiments. Secondly, during the process of the location estimation, the theoretical results on the pre-existing localisation algorithms which can achieve a good trade-off between the accuracy of location estimation and the computational cost are evaluated, including the weight least-squares (WLS)-based solution and the Extended Kalman Filter (EKF)-based solution. In order to use the pre-existing algorithms in the practical source localisation, the proper adjustments are implemented.…

▼ Cultural localisation of websites represents a relevant managerial practice. Studies have indicated that when tailoring web content and website design to fit the needs, characteristics and preferences of target audiences, individuals tend to develop more positive attitude toward the site, have higher purchase intention and greater ease of use, for example. However, the investigation of the effects of cultural localisation of websites has been limited to the context of company websites. The current localisation literature, for examples, does not include websites which clearly triggers hedonic motivation in users. Moreover, it fails to encompass the users’ motivation and involvement and the product types as moderating factors of perception and behavioural intention. Also, the main theoretical rationale employed to justify the effectiveness of the cultural localisation of websites involves only the reduction of cognitive effort applied by users when interacting with culturally congruent sites. This thesis aimed at understanding the effects of cultural localisation of tourism destination websites on users’ perceptions of the destination and its site. Tourism sites were chosen for a series of reasons. First, the leisure tourism context triggers hedonic motivation in individuals. Also, individuals tend to apply their ideal or situational self when conducting evaluations and judgements in the leisure tourism context. Thus, the theoretical proposition stated in this thesis predicted that cultural incongruity between tourism destination websites and users was expected to generate more positive perceptions of the place and its websites in users when compared to culturally congruent sites. In order to test the theoretical proposition and address the aim of the thesis, a two stage research was conducted. The first stage consisted of an exploratory study of 130 destination websites from New Zealand, China and India. The study allowed an investigation of the depiction of cultural values, and the identification of cultural markers, in tourism destination sites. The second stage of the research involved an experiment. An experimental website of a fictitious tourism destination was developed and culturally localised for New Zealanders, based on findings from the exploratory study. Cultural values and cultural markers represented the two independent variables of the main study, and each variable was treated in two levels: congruent and incongruent. 400 New Zealand undergraduate students participated in the study, 100 per condition. As predicted, results indicated that incongruent cultural values and cultural markers led to more positive destination image, higher willingness to travel and more positive perception of the website’s design. No significant effect was found on participants’ online trust, attitude toward the site and perception of navigability. The results are interpreted in light of motivation and self concept theories and the characteristics of the product type. Thus, the theoretical rationale adopted to explain the… Advisors/Committee Members: Gnoth, Juergen (advisor).

Cette thèse porte sur l’exploitation d’une population nomade afin de colporter des informations dites ‘atomiques’ de rencontres entre entités fixes ou mobiles pour des applications diverses basées sur la localisation et la traçabilité. Répondre à ces besoins en milieux confinés s’avère un défi, que ce soit dans un contexte industriel, médical ou social. Parmi les solutions existantes, le système GPS (Global Positioning System) offre des résultats encourageants lorsqu’il s’agit de connaître une position en extérieur. Cette solution n’est plus utilisable en intérieur tel que dans une mine par exemple, en raison des caractéristiques du signal fortement perturbées dans ce type de milieu. Le fil directeur de ce travail consiste à proposer un modèle utilisant la technologie des réseaux de capteurs sans fil afin de modéliser et de trouver des solutions à des problématiques allant de la localisation en milieux confinés au suivi et à la reconstitution de trajectoires d’entités mobiles. Les solutions proposées dans cette thématique doivent être tolérantes aux délais. Après avoir présenté les constituants de notre modèle générique de colportage, une instanciation de ce modèle a permis de nous pencher sur un cas de localisation et de traçabilité dans un espace confiné. Les résultats de simulation et d’expérimentation ont montré l’impact de notre mécanisme de colportage sur la qualité de l’information recensée concernant les déplacements et les rencontres des entités mobiles. Outre la proposition d’un modèle générique, la contribution de cette thèse comporte des mécanismes de colportage (et de filtrage) de l’information par des entités mobiles contraintes en taille mémoire.

This thesis focuses on the exploitation of a nomadic population to pass around information called contact event which represents the recording of a meeting between fixed or mobile entities for localization and tracking applications. Addressing these needs in confined environments is a challenge, whether in an industrial, medical or social context. Among the existing solutions, the GPS (Global Positioning System) provides encouraging results for outdoor localization. However, this solution is not operational in confined environments such as mines, due to the signal characteristics highly disturbed in this type of environment. The guiding principle of this work is to propose a model using the technology of wireless sensor networks for modeling and finding solutions for localization and tracking mobile nodes in confined areas. The new approach proposed in this thesis is inspired by the principle of ‘store-carry-forward’ of Delay-Tolerant-Network (DTN). After presenting the components of our generic model, an instantiation of this model has allowed us to address a localization and tracking case in a confined area. The simulation and experimentation results show the impact of our filtering mechanism on the quality of the knowledge collected concerning the movements and meetings of the mobile nodes.

▼ En utilisant des amers visuels géoréférencés. Le processus d’appariement de flux d’images avec ces amers est guidé par les incertitudes des poses. On ajoute des contraintes absolues dans le système d’équations de l’ajustement de faisceaux. La dérive de la trajectoire du véhicule de cartographie est très fortement réduite. Chaque étape de l’algorithme est évaluée sur des séquences d’images réelles avec une vérité terrain. Le véhicule de cartographie est le processus de collecte des données géo-spatiales. Ces véhicules sont souvent équipés de deux types de capteurs: télédétection (caméras, Lidar, Radar) et géolocalisation (GNSS, IMU, Odomètre). Le géoréférencement des données précis et robuste constitue un enjeu majeur pour la mise en œuvre des systèmes de cartographie mobile. En effet, en milieux urbains denses, les phénomènes de masquages GNSS et de trajets multiples pertubent les mesures de GNSS et conduisent à des erreurs de localisations importantes. Les centrales inertielles de grandes précisions permettent de combler les manques de localisation GNSS. Elles garantissent une dérive de position suffisamment faible pour obtenir la qualité de géoréférencement nécessaire pour la numérisation à des fins cartographiques. Aujourd’hui, la maturité des systèmes de géolocalisation hybride (GNSS/IMU/Odomètre) offre des solutions industrielles fiables pour la collecte de données géoréférencées. Les agences de cartographie nationales et privées ont commencées à faire des acquisitions de données nécessaires à la constitution de données géo-spatiales à très grande échelle. Cependant, le coût très onéreux des systèmes de géolocalisation intégrant des centrales inertielles de grandes précisions restreint leur utilisation à la constitution de données géoréferencées. Une solution plus abordable est nécessaire pour équiper les véhicules employés pour les mises à jour régulières de ces données.L’objectif de cette thèse est de proposer une solution abordable de géolocalisation utilisable sur un grand nombre de véhicules pouvant être mobilisés pour la mise à jour de données géoréferencées.Nous proposons d’utiliser une ou plusieurs caméras sur un véhicule comme un système de géoréférencement. En effet la trajectoire du véhicule peut être estimée par une technique d’odométrie visuelle. Pour limiter la dérive de la trajectoire due à l’accumulation des erreurs, nous proposons de le recaler sur un ensemble d’amers visuels précisément géoréférencés. Ces amers sont reconstruits en utilisant les données géoréferencées générées par des systèmes de cartographies précis et onéreux. Les caractéristiques de route telles que les signalisations horizontales et verticales ont été choisi en tant que amers visuels.Un algorithme d’ajustement de faisceaux local a été adapté pour estimer la pose des caméras en utilisant un flux d’images acquis par un ou plusieurs caméras embarquées sur celui-ci.

L’objectif de la thèse est de proposer une modélisation des comportements résidentiels des ménages : le choix de changement de résidence (ou de déménagement) et le choix d’une nouvelle localisation. Ce type de modèles vise à prévoir la probabilité qu’un ménage change de résidence et son choix en matière de nouvelle localisation, en fonction d’un certain nombre de variables explicatives. Dans notre cas, la modélisation est fondée sur la théorie des choix discrets (approche de l’utilité aléatoire). La recherche s’appuie sur le cas lyonnais, le modèle étant construit sur l’aire urbaine de Lyon, sur des données de l’année 1999. En termes de résultats, du côté de la mobilité résidentielle, il faut retenir que les variables qui expliquent la variation du degré de mobilité (du taux de déménagement) des ménages sont l’âge de la personne de référence du ménage, le nombre d’enfants et le statut d’occupation du logement. En ce qui concerne la localisation des ménages, les préférences des ménages pour une zone ou autre sont liées aux caractéristiques de celles-ci et notamment à l’accessibilité aux différentes opportunités et services, ce qui confirme que parmi les facteurs qui influencent le comportement de localisation des ménages on retrouve les accessibilités, et donc, l’hypothèse de l’existence d’un lien entre transports et urbanisme. On a également trouvé que les caractéristiques des ménages comme l’âge de la personne de référence, le revenu ou le nombre de personnes ont une influence sur leurs choix de localisation. L’étude et les résultats des modèles suggèrent que des améliorations et nouvelles pistes de recherche sont possibles. Ainsi, du côté de la mobilité résidentielle, il pourrait y avoir d’autres variables qui motivent les ménages à changer de logement, comme des caractéristiques des logements, de l’environnement résidentiel ou d’autres caractéristiques des ménages non observées. Il serait aussi intéressant d’estimer le modèle de localisation a un niveau géographique encore plus fin (à l’îlot). D’autres alternatives de modélisation des décisions résidentielles des ménages seraient de modéliser une structure hiérarchisée des choix, par un modèle logit hiérarchique ou emboîté, ou bien de modéliser la trajectoire de vie, avec ses composantes familiale, résidentielle et professionnelle, qui sont en interdépendance (à condition de la disponibilité des données nécessaires).

The objective of the thesis is to propose a modeling of the residential behaviors of the households: the choice of change of residence (or removal), and the choice of the new location. This type of models aims at envisaging the probability that a household changes residence and its choice of new location, according to a certain number of explanatory variables. In our case, modeling is founded on the discrete choice theory (random utility approach). Research is based on the Lyons case, the model being built on the urban area of Lyon, on data of the year 1999. In terms of results, side of residential mobility, it should be retained that the variables…

▼ Zirconium alloys are utilised by the nuclear industry as a structural and clad material for use in power reactors. The integrity of these components is crucial for efficient and safe generation of power. During operation, neutron irradiation and hydride formation due to corrosion impact yield stress and ductility. The aim of the present PhD project was to characterise the change in deformation behaviour of zirconium alloys exposed to irradiation and hydrides using a combination of high resolution digital image correlation and electron backscatter diffraction techniques. In order to generate accurate displacement maps using digital image correlation, a pattern at a suitable length scale must be generated on the surface of the sample. The styrene vapour assisted gold remodelling technique was chosen to produce a speckle pattern. The remodelling temperature and time were optimised and strain maps of non-irradiated ZIRLO were created to ensure suitability for investigating sub-grain scale deformation. Proton irradiation was performed as a surrogate for the neutron flux encountered in-reactor and strain localisation was studied in Zircaloy-4 samples irradiated to 0.1 dpa. Dramatically enhanced strain localisation was observed as a result of irradiation and was attributed to the creation of defect-free channels. Due to the texture in zirconium alloys, deformation along different principal directions was performed and slip system activation was quantitatively measured for both non-irradiated and irradiated conditions. Differing slip system activation was observed for loading along the rolling direction compared loading along the transverse direction, however no significant change in slip system activation was observed due to irradiation. Finally, strain localisation in a sample containing hydrides induced by cathodic charging and homogenisation heat treatment was investigated. The average amount of strain observed within hydrides and second phase particles was lower than that in the matrix and shear bands were observed to terminate at transgranular hydrides. As well as providing an improved understanding of the impact of irradiation and hydrides on strain localisation in zirconium alloys, the methods developed will allow further investigation of deformation behaviour in corrosion-susceptible materials. Quantitative displacement maps and slip system activation data will allow for validation of crystal plasticity models, used to predict deformation behaviour of components subject to in-reactor degradation.

La mitogaligine est une protéine codée par le gène galig, un gène inducteur de la mort cellulaire. Préalablement, il a été montré au laboratoire que cette protéine mitochondriale pouvait induire la mort cellulaire selon une voie alternative de l’apoptose. Nos études indiquent que la mitogaligine peut également être adressée au noyau où elle exerce aussi une activité cytotoxique. Le signal d’adressage nucléaire est non conventionnel et lié à une répétition d’acides aminés. Il n’est fonctionnel que si le signal de localisation mitochondriale est aboli. La fonction cytotoxique de la mitogaligine pourrait donc être régulée par son adressage subcellulaire. De nombreuses protéines apoptotiques sont régulées par des modifications post-traductionnelles. La mitogaligine possède différents sites de phosphorylation potentiels. Plusieurs d’entre eux ont été mutés afin de mettre en évidence une éventuelle implication de cette fonction dans l’activité de la mitogaligine. La mitogaligine non mutée subit une ou plusieurs coupures protéolytiques. La mutation des résidus thréonines 29 et 73 en résidus phospho-mimétiques diminue cette protéolyse mais aussi la cytotoxicité de la protéine. Le même type de mutations de la thréonine 38 et la sérine 39 provoque une délocalisation de la protéine. La dernière partie de la thèse s’intéresse plus particulièrement à l’interaction fonctionnelle entre la mitogaligine et Mcl-1, une protéine anti-apoptotique de la famille-Bcl-2. La coexpression de galig et Mcl-1 réduit la mort cellulaire induite par l’expression de galig et la surexpression de galig réduit la production endogène de Mcl-1. Ces résultats montrent une implication de galig dans une voie de régulation de l’apoptose. Galig pourrait donc représenter une cible thérapeutique pour restaurer la mort cellulaire dans des cellules surexprimant des protéines antiapoptotiques de la famille Bcl-2.

Mitogaligin is a protein encoded by galig, a cell death gene. Previously, it has been shown in our laboratory, that this mitochondrial protein induces cell death through an alternative pathway of apoptosis. In this report, we show that mitogaligin can also be addressed to the nucleus where it exhibits also a cytotoxic activity. The nuclear localization signal is not conventional, based on a repetition of amino acids, and function only if the mitochondrial localization signal is inactivated. Thus, the cytotoxicity of mitogaligin could be regulated by its subcellular localization. A large number of apoptotic proteins are regulated by post-translational modifications. Mitogaligin has several potential sites of phosphorylation. Some of them have been mutated to highlight the possible role of phosphorylation in the mitogaligin activity. The wild type protein undergoes one or several proteolytic cuts. Replacement of the threonines 29 and 73 by phospho-mimetic residue decrease mitogaligin proteolysis and also mitogaligin cytotoxicity. The same type of mutation on threonine 38 and serine 39 induces a re-localization of mitogaligin outside mitochondria. The last…

▼ Background HER2-positive breast cancer is a poor prognostic subgroup, even if treated with anti-HER2 directed therapy. Trastuzumab is an important HER2-targeting antibody but only limited patients respond to this drug, and acquired resistance is a common problem. HER3 has been shown to be a key candidate in mediating resistance to trastuzumab and other ErbB inhibitors. The aims of the project are to investigate the resistance mechanisms and the relevant biomarkers in relation to trastuzumab treatment and resistance in HER2-positive breast cancer, in particular, HER3 subcellular localisation and HER3 phosphorylation. Methods Effects of trastuzumab on HER3 subcellular localisation and HER3 phosphorylation in relation to MET receptor were studied using western blots, nuclear fractionation, confocal microscopy, and immunoprecipitation in a panel of HER2-positive cell lines, including SKBr3 and BT474 breast cancer cells in which trastuzumab resistance was induced by long-term drug exposure. Effects of drug and knockdown experiments were tested by cell viability and proliferation assays. HER3 and MET expression was assessed by immunohistochemistry in xenograft tumours and human tissue samples, and clinical impact was assessed in different cohorts of HER2-positive breast cancer patients. Results Acquired trastuzumab resistant SKBr3 cells showed an increase of nuclear HER3_100kD, which was derived from C-terminus of HER3. Nuclear HER3_100kD could be due to the proteolytic cleavage of HER3 since it was reduced by ADAM17 or gamma-secretase inhibitor. In a panel of HER2-positive cell lines and xenograft samples, nuclear HER3 was observed only in the resistant cells. In addition, nuclear HER3 was associated with poor progression-free and overall survivals in HER2-positive breast cancer patients. It was also found that HER3 phosphorylation was maintained in acquired trastuzumab resistant cells, which was contributed by the ligand independent interaction of MET and HER3. Higher MET expression was associated with better overall survival in HER2-positive, breast cancer patients who were not treated with trastuzumab. Conclusions Nuclear HER3 was found in trastuzumab resistant cells and appeared to result from HER3 proteolytic cleavage mediated by ADAM17 and gamma-secretase. Further studies are required to investigate its mechanism and to identify the HER3 cleavage sites. MET was a key factor in maintaining HER3 phosphorylation during trastuzumab resistance. Lastly, nuclear HER3 and MET could be two potential biomarkers in HER2-positive breast cancer.

▼ The localisation of radiating sources of electromagnetic waves in the near-field of a receiver antenna array are of use in a vast range of applications, such as in microwave imaging, wireless communications, RFID, real time localisation systems and remote sensing etc. Localisation of targets embedded in a background dielectric medium, which is usually the case in Radar, UWB imaging and remote sensing, can be done using the scattered response received at the antennas. In this thesis, we investigate methods for localisation of both near-field radiating as well as scattering sources of electromagnetic waves. For localisation of near-field radiating sources, planar antenna arrays such as concentric circular ring array (CCRA), uniform rectangular array (URA), uniform circular array (UCA) and elliptic array are employed. The thesis employs beamforming and parameter estimation methods for localisation and proposes novel algorithms that are based on standard Capon beamformer (SCB), subspace based superresolution algorithms (MUSIC and ESPRIT) and maximum likelihood (ML) methods. Complex array geometries can suffer from severe mutual coupling and are susceptible to array modelling errors. These errors impair the performance of algorithms that are used for beamforming and parameter estimation for localisation. To overcome the limitations of standard Capon beamformer (SCB), a modified capon beamforming method is proposed to make SCB robust against both array modelling error and mutual coupling effects. The proposed method is applied with planar antenna arrays for localisation of near-field sources. Planar arrays are also used with MUSIC and ESPRIT superreso lution algorithms for performance investigation in a near-field source localisation. Here, to reduce the computational burden of standard MUSIC and ESPRIT algorithms, a novel method to estimate the range using the time-delay is proposed. Lastly, to overcome the performance limitations of superresolution algorithms with planar arrays, the ML estimation is investigated for the localisation of near-field sources using planar arrays. Since ML method cannot automatically detect the number of sources, a novel method is proposed here for detecting the number of sources. Finally, performance comparisons of all the methods under investigation have been presented using computer simulations. In order to localise targets embedded either in homogeneous or in heterogeneous background medium, we employ time reversal (TR) techniques that localise based on the received scattering responses from the embedded targets. We propose a novel beamspace- TR technique that can achieve efficient focusing on targets embedded in both a homogeneous and heterogeneous dielectric background media. It is shown that prior to back propagation, applying beamspace processing to the TR operation in the receiving mode helps achieve a reduced dimensional computation and achieves selective focusing. We have also proposed beamspace-TR-MUSIC algorithm for improving the resolution of …
