Potwin, Albert F. "A Dues Management expert system for inventory managers at retail stock points." Thesis, Monterey, California. Naval Postgraduate School, 1988. http://hdl.handle.net/10945/23183.
Full textAbstract:
The job of the retail inventory manager at Navy Stock Points is complex and labor intensive. The inventory manager deals with a vast array of information in the form of reports from the Uniform Automated Data Processing - Stock Point (UADPS-SP) system. Because the responsiveness of the Navy Supply System depends upon the effectiveness of inventory managers, Navy Stock Points must find a way to process their ever increasing information work-loads more efficiently than before. Improvements in productivity and training are feasible through the application of expert systems technology. This thesis presents the continuation of the design and development process of an expert system for the task of Delinquent Dues Processing. The area of retail inventory management dealing with System Cancellations Processing was also implemented to establish a more complete Dues Management System. The resulting revised prototype presents a system with more problem solving capabilities and a more natural user friendly interface. Keywords: Computer programs. (KR)

Full textAbstract:
Customer experience has become more difficult for companies to control with the expanding number of touch points that the companies must be aware off. One of the major reasons behind the expanding number of touch points has been digitalization. The financial sector is not excluded from this change. With the digitalization continuously improving and new financial technology (fintech) being developed, things might have changed. For example, bank offices and employees have been viewed as important in earlier studies, but has this changed? What is important and affects the customer experience in the Swedish financial sector today? The purpose of this paper is to gain a deeper understanding of which factors of banking services are considered important by customers today and whether there has been a shift since earlier studies. Thereby, we seek to establish what impacts the customer experience in financial institutions today. To find the answer to the purpose, a qualitative and quantitative study were conducted. The results of the full study show that employees are, as earlier studies have shown, still considered important when conducting a bank errand. However, in what context the employees are important seems to have changed. The results show that the quality that is delivered by the staff is important, while in earlier studies the relational aspect has been more important. Furthermore, the results show that bank offices are no longer considered important for the customer experience. Therefore, a shift can be identified. The study also show that it is important for the customer experience that the banks offer different channels for the customers to reach the bank. Furthermore, having the option to choose whether to resolve the bank errand on your own or obtain help from the bank is important for the customer experience. These two aspects are connected to the digital development of the industry. The results of the earlier research, referred to in this study, has not found these two aspects important. Our study therefore shows a significant shift, compared to earlier studies, in what customers consider important in contact with financial institutions.

Cassou, Fabrice. "Les réseaux de points de vente face au défi de l'uniformité du concept : le cas du commerce coopératif et associé." Thesis, Rennes 1, 2016. http://www.theses.fr/2016REN1G025/document.
Full textAbstract:
Les réseaux de commerce coopératif et associé sont des groupes de détaillants, propriétaires de leur(s) point(s) de vente, qui mettent en commun leurs moyens (achat, marketing, communication, financement, logistique, etc.) et développent des politiques communes. L'objectif de cette recherche est de démontrer comment des réseaux de commerce coopératif et associé, avec le double statut de leurs membres, c’est-à-dire clients et copropriétaires des structures centrales, peuvent générer des synergies aussi efficaces que celles des réseaux mixtes (coexistence de succursales et de franchises dans le même réseau) afin de faire face au défi de l'uniformité du concept, nécessaire à la survie et au développement de tout réseau de points de vente. Le maintien de l'uniformité consiste à respecter les éléments clefs du concept. Une étude de quatre cas a été menée. Les résultats de la recherche qualitative mettent en évidence l'existence de différents processus qui émergent de manière centralisée (contrats, incitations et persuasion), décentralisée (confiance, implication organisationnelle et contrôle informel) et mixte (solidarité, mimétisme et enculturation). Tous ces processus ont été opérationnalisés et testés empiriquement avec un échantillon de 245 commerçants coopérateurs ou associés, issus de 53 réseaux différents, représentant tous les secteurs d'activité définis par la FCA (Fédération du Commerce coopératif et Associé). L'analyse s’est fondée sur une modélisation par équations structurelles de type PLS. Un modèle de management du défi de l'uniformité du concept des réseaux de commerce coopératif et associé est proposé. Ce sujet est crucial pour cette forme de réseaux. Le respect de l'uniformité du concept peut contribuer à renforcer l'image de marque en servant d’identifiant et de garantie pour les consommateurs et les candidats susceptibles de devenir coopérateurs, de garder un concept distinctif des concurrents, de réaliser des économies d'échelle et d’éviter les comportements opportunistes qui peuvent nuire à la performance globale du réseau<br>Retail cooperatives and independent associated retail networks are groups of retailers, owners of retail and service stores that pool their means (in terms of purchasing, marketing, communication, funding, logistics, etc.) and develop common policies. The objective of this research is to demonstrate how retail cooperatives and independent associated networks, whose cooperators with their double status, as both customers and co-owners of the cooperative, can generate synergies as efficiently as in plural form networks (coexistence of company and franchise units in the same network) in order to face the challenge of network uniformity and thus both grow and survive as does every other kind of network. In this research, we will focus on network uniformity. Maintaining uniformity means respecting the core components of the network concept. A four-case study has been conducted and the findings of our qualitative research highlight the existence of different processes which emerge from a centralized top- down approach (Contracts, Incentives and Persuasion), a decentralized bottom-up, or horizontal approach (Trust, Organizational commitment and Informal control) and from a mixed approach (Solidarity, Mimesis and Enculturation). All of these processes were operationalized and tested empirically with a sample of 245 cooperators or independent associated retailers from 53 different networks, representing all the sectors of activity defined by the FCA (French Federation of Retail Cooperatives and Retail Independent Associations). The analysis was based on PLS structural equation modeling. This research suggests a model of management to face the challenge of concept uniformity at the heart of retail cooperatives and independent associated networks. This subject is of great interest to all retail cooperative networks. Maintaining uniformity can help to reinforce a network’s image as an indicator and guarantee for consumers and cooperative candidates. It will differentiate them from their competitors, contribute to improving better purchasing conditions and thus achieving important cost reductions, as well as avoiding opportunistic behaviors that can harm a network’s performance

Using qualitative research with case studies of firms in the Australian retail sector, this thesis explores the link between brand differentiation, customer insights, and strategy development to deliver a unique customer experience. The research focus is how brand expression is driven by customer insights. Findings indicate that customer experience is made tangible by the strategic design and alignment of the brand's expression and is crucial to retail success. A significant practical outcome is the development of the Brand Differentiated Model. Created as a tool to potentially assist retailers develop brands from the 'inside out' and confront future disruptions.

Guard, Misty Ann. "Business innovation and regulatory enforcement: case studies of the big box retail industry and enforcement of RCRA." Thesis, Georgia Institute of Technology, 2010. http://hdl.handle.net/1853/33940.
Full textAbstract:
The purpose of this research is to examine the following research question: how has enforcement of Resource Conservation and Recovery Act (RCRA) adapted to the Big Box business system innovation? Additionally, the study explored the possible nature of regulatory choke points that may emerge from the enforcement of RCRA in the Big Box retail system. This study used contingency theory to establish a foundation for analysis of the Big Box business system innovation through identification of structural elements, external influences, and their subsequent interactions associated with the Big Box retail system in terms of environmental compliance with the RCRA enforced by the United States (US) Environmental Protection Agency (EPA). This research employed an embedded comparative case study design using the comparison of two Big Box firms, Walmart Stores, Inc. and Target Corporation, nationally and for the following states with opposing enforcement strategies: Arizona, Kentucky, Missouri, and Texas. The data used was obtained from third-party federal or firm-maintained sources.
Findings indicate Walmart adheres to the structural models developed using contingency theory principles and incurs more impacts from regulatory agencies due to the enforcement of RCRA. Furthermore, it was observed that inspections of the firms are not distributed throughout the organizational structural elements by all states. Additionally, the use of different enforcement strategies resulted in the emergence of regulatory choke points by Arizona, Kentucky, and Texas; however, Missouri appears to balance enforcement without causing a regulatory choke point.
This research has identified that the enforcement of RCRA has not universally adapted to the demands of the Big Box business system innovation. Agency implications, firm implications, directions for further research, and continued development of a regulatory choke point theory are discussed.

Full textAbstract:
Problem that emerges quite often when managing IT in retail industry is not understanding individual details and bindings between elements within this activity. Therefore, this diploma thesis is, with the help of MBI methodology, trying to draft frameworks for at least two scenarios which may emerge with high probability when managing IT in retail: choice and implementation of retail information system and corresponding hardware and subsequent service maintenance of chosen solution. These scenarios contain individual parts of addressed issues in form of tasks and their key activities; each single one of them defining processes, possible problems and finally bonds with internal and external elements, mainly because such bonds very often in a major way affect solution of said issues. Main goal of this thesis is to show these segments of reality from retail-and-its-surroundings-as-a-whole point of view, providing users of the methodology with description of the best ways to cope with the industry-specific problems in a practical and graspable way.

Full textAbstract:
The retail companies have a very conservative approach concerning IT expenses and innovations. Maybe for this reason, it is now the best time for changing an IT infrastructure and a complex retail solution. Most of the companies need to optimize their processes due to the financial crisis to achieve a competitive advantage. There are many differences among the retail companies - these differences may cause that an implementation of a software solution is tricky. It is important to be aware of such aspects when implementing the software solution. The main aim of this work is to design, extend and optimize a methodology of implementation of a complex retail solution. The new methodology is quite general - it might be used for an implementation of any POS solution. The goal of new methodology is to improve top line and margin. Finally, it shall bring a bigger satisfaction to the customer. I divided this work into several main chapters. First chapter is dedicated to the specifics of retail companies - how they work, which processes they use, how much they invest into the IT. The second part contains an analysis of POS solutions available on the Czech market and a brief description of the particular software solutions with their market share. The third part is dedicated to the RIM methodology designed by Microsoft Corporation. The fourth - and the main part of my work - contains an extension of the RIM methodology. In the final part I sum up the main achievements of this work and evaluate the new extended methodology. In the appendix, I compared some examples with the real figures to the new methodology.

In this work we address to the problems of the loan origination decision-making systems. In accordance with the basic principles of the loan origination process we considered the main rules of a clients parameters estimation, a change-point problem for the given data and a disorder moment detection problem for the real-time observations. In the first part of the work the main principles of the parameters estimation are given. Also the change-point problem is considered for the given sample in the discrete and continuous time with using the Maximum likelihood method. In the second part of the work the disorder moment detection problem for the real-time observations is considered as a disorder problem for a non-homogeneous Poisson process. The corresponding optimal stopping problem is reduced to the free-boundary problem with a complete analytical solution for the case when the intensity of defaults increases. Thereafter a scheme of the real time detection of a disorder moment is given.

Supermarkets have grown 45% during the last four years and the new convenience stores gather all competitive advantages required by the sector. Industry has adapted to the new Peruvian in order to cover the needs generated by a digital age offering solutions that give timely information, comfort and modernity when acquiring a new product. In 2017, 414,000 grocery stores were counted in Peru, which were forced to adapt and improve their services. This research project aims to come up with a solution to bring the grocery stores into the twenty-first century, and thus, to increase their gross margin and ensure their continuity. A methodology connecting the requirements of the grocery stores that invest the most in the city of Lima to the needs of the mass consumption companies by means of a platform that digitalizes ads at the point of sale driven by digital advertising is presented here. Currently, the product benefits 40 grocery stores in the city with a new customer service channel that allows to increase their sales by 20%.

Full textAbstract:
Omni-channel has become a major player in retail marketing today. It is steadily gaining popularity among retailers because of its capability of providing consistent and seamless customer shopping experience. Omni-channel allows sales to take place via the variety of channels as it implements cross-channel business model. With the emergence of technologies like mobile devices, E-commerce and social media, the way of retailing as we used tohas changed significantly.Customers of today use different variety of channels and devices on their shopping journey. Omni-channel provides retailers the opportunity to engage and build strong retail relationship with customers, offering different retail channels for customer to use. Store pickup is one of the strategies offered by Omni-channel as it presents an unique way of purchasing to customers. However, selling on a single channel is not enough due to the increasing demand in better shopping experience from customers. Such demand has put retailers in a position to rethink and redesign their retail marketing strategies. We believe cooperating online with offline channel is the response to the demand.This work aims to find answers to the study questions regarding retailer requirements and E-commerce platform to be integrated. The obtained analysis results provide answers to the study questions indicating that retailers are looking for strategies to fulfill thier customer requirements as their shopping demand continues to increase. The analysis results further show that WooCommerce as an E-commerce platform is most sutiable for the integration out of the three considered platforms. The integration is part of the implementation phase that demonstrates the proof of concept of Omni-channel strategy. As a proof of concept, a prototyp is developed and implemented. The implementation result provides an integrated system that seamlessly combines online and offline channels in regard of store pickup as part of Omni-channel strategy. However, the results of this work only provide information and demonstrate an initial step towards completed Omni-channel and that alot of work is required in order to reach the full Omni-channel retail.

Full textAbstract:
In spite of the documented success of Pathogen Reduction and Hazard Analysis and Critical Control Points (PR/HACCP) at the processing level, farm-level and retail-level application is optional. Several factors impact the gap of food safety regulations from farm to fork. This thesis focuses on the retail level. At the retail level, pathogen survival and the associated ability to cause further disease to humans even after being subjected to certain processing and packaging conditions have varying implications on the probability of sickness or death. This issue also arises over the fact that, sometimes, appropriate handling and processing instructions are not properly followed by consumers. The primary goals of the project are to develop an optimal food safety intervention strategy that incorporates risk, cost, and the value of pathogen reduction with alternative control mechanism. We wish to evaluate incentives for PR/HACCP-like planning and adherence to best management practices that promote safe food production. These incentives will be evaluated for the retail level. In addition, we will develop optimal intervention strategies for ready-to-eat meats and poultry products that incorporate risk assessment, cost of intervention, and the value of risk reduction of alternative strategies for the farm-to-table continuum. The model adopted in this study is an expansion of the stochastic optimization model developed by Nganje, Kaitibie, and Sorin (2005) to include the optimal intervention strategy at the retail ( consumer) level. These components are simulated with firm-level microbial data at the processing and retail level using stochastic optimizer software. Stochastic dominance was also used to compare across the optimal strategies and determine if there is one clear choice that is preferred. This allowed us incorporate risk preferences of firms. The scenario method was used to determine what factors would likely affect the adoption of PR/HACCP at the retail level. Finally, this thesis provides firms and policymakers a direction for future options concerning risk mitigation strategies.

Full textAbstract:
Déchet industriel, la fluoro-anhydrite peut être utilisée pour la réalisation de chapes auto nivelantes et autolissantes. Elle nécessite un retraitement visant à lui assurer une bonne stabilité dimensionnelle alliée à des résistances mécaniques convenables. L'un des procédés de retraitement utilisé consiste à neutraliser la fluoro-anhydrite par un ajout de chaux (Ca(OH) en phase vapeur (procédé ANHYSOL). Nous montrons dans cette étude que l'addition de chaux doit se faire à des taux bien déterminés car une quantité excessive accroît le retrait. Par ailleurs, nous mettons en évidence que l'effet des fluctuations des caractéristiques du produit fini peut être considérablement atténué si l'on veille à un strict respect des conditions d'application (choix de granulats convenables, adoption de procédés de cure appropriés, recours au fibrage,. . . ) L'essentiel de l'étude est consacré aux principaux paramètres influant sur le retrait des chapes récemment mises en place et à la mise au point de procédures permettant de minimiser les variations dimensionnelles aux jeunes âges<br>Fluoro-anhydrite, which is an industrial waste, can be used to develop self-levelling floors. To get both low shrinkage or swelling values and good mechanical strengths, anhydrite has to be treated to eliminate residual acidity. One of the possible treatments is to add slaked lime (Ca(OH) )when anhydrite is steam-cured (ANHYSOL process). Our research work shows that this quantity of lime must be limited in order to keep shrinkage in permissible range. This work also shows that the shrinkage increase due to the fluctuations of the treated product can be reduced when good aggregates or fibres are used, and the conditions of curing are well defined and applied. The main part of this study deals with the parameters having an influence on the initial shrinkage of floors and the adequate solutions which can be developed to limit this phenomenon

Full textAbstract:
<p> Throughout the nation, grocery retailers are reentering underserved communities amidst growing public awareness of food deserts and the rise of federal, state, and local programs incentivizing urban grocery stores. And yet, even with expanding research on food deserts and their public health impacts, there is still a lack of consensus on whether grocery stores truly offer the best solution. Furthermore, scholars and policymakers alike have limited understandings of the broader neighborhood implications of grocery stores newly introduced into underserved urban communities.</p><p> This dissertation analyzes how local organizations and agencies pursue grocery development in order to understand the conditions for success implementation. To do this, I examine the historical drivers, planning processes, and outcomes of two extreme cases of urban grocery development: a Fresh and Easy Neighborhood Market (a chain value store) in San Francisco's Bayview Hunters Point and the Mandela Foods Cooperative (a worker-owned cooperative) in Oakland's West Oakland districts. </p><p> Through a comparative institutional analysis, I find that both Fresh and Easy and Mandela Foods reflect distinctive neighborhood revitalization legacies, critical moments of institutional capacity building, localized versions of national policy narratives, and the role of charismatic leaders in grocery store implementation. While national narratives shape the rhetoric of urban grocery development, ultimately local context dictates how food access issues are defined, who addresses them, and how. These findings suggest that federal grocery incentive programs should: 1) maintain a broad framework that enables local communities to define food access problems and their solutions on a case-by-case basis, 2) encourage diverse solutions not limited to grocery stores and supermarkets, and 3) emphasize community reinvestment goals.</p>

Ego, Anne. "Définitions du retard de croissance intra-utérin : intérêt des courbes ajustées individuelles de poids fœtal." Paris 6, 2008. http://www.theses.fr/2008PA066303.
Full textAbstract:
Le retard de croissance intra-utérin est une pathologie fréquente et complexe en médecine périnatale, mais sa définition et son dépistage ne sont pas clairement définis. De nombreuses courbes de références de poids de naissance sont utilisées dans le monde afin d’identifier les enfants de faible poids. Cependant l’utilisation d’un seuil de poids (le plus souvent le 10ème percentile) ne tient pas compte du potentiel de croissance individuel. Des alternatives consistant à modéliser la croissance et rechercher une cassure de la courbe existent, mais sont difficiles à utiliser. En 1995, Jason Gardosi a suggéré la construction de courbes ajustées sur des facteurs individuels dont le sexe foetal, la taille et le poids maternels, la parité, et cette approche semble montrer un bénéfice dans l’identification d’enfants à risque. En l’absence de courbes de poids satisfaisantes en France, un modèle ajusté adapté aux naissances de notre pays a ainsi été développé. Ce modèle, appliqué à un large échantillon multicentrique (N=56606), montre une amélioration du dépistage de la morbidité et mortalité périnatale liées au faible poids. La question du choix des paramètres d’ajustement dans ces modèles reste à débattre. L’exclusion du facteur parité ne semble pas altérer la pertinence du modèle. En France, l’utilisation des courbes ajustées individuelles à l’aide d’un outil validé pourrait améliorer les soins en maternité et harmoniser la définition du RCIU entre cliniciens et épidémiologistes. Cependant, leur impact sur les soins et la santé périnatale nécessite d’être évalué de façon prospective en pratique clinique.

Full textAbstract:
La percée des applications mobiles d’aide à l’achat est un phénomène récent. L’usage croissant du smartphone au sein du point de vente (i.e. plus de 70% des consommateurs) a conduit les distributeurs à développer ces outils pour aider les consommateurs à faire des achats plus éclairés. Cependant, à l’image des Self-services technologies (e.g. caisses automatiques), les applications d’aide à l’achat soulèvent de nombreuses questions, notamment concernant les facteurs de création de valeur pour le client. L’objectif de notre recherche consiste dès lors à mesurer la valeur d’une application mobile d’aide à l’achat, par le client, dans le contexte d’un point de vente physique. Il s’agit aussi d’en déterminer les conséquences sur la relation au point de vente. Ce travail s’appuie sur la littérature portant sur le concept de la valeur et sur les applications mobiles d’aide à l’achat. Une recherche qualitative exploratoire sous forme de focus groups permet de mettre en exergue les bénéfices et les coûts liés à l’usage des applications mobiles au sein du point de vente. Divers éléments conditionnels pouvant modérer les effets de liens de ces applications sont également identifiés : type de point de vente (alimentaire versus multimédia), type d’application (« Pull » versus « Push ») et degré de personnalisation (personnalisé versus non personnalisé). Cela nous conduit à la construction d’une échelle de mesure de la valeur d’usage d’une application et à l’élaboration d’un modèle conceptuel qui reprend l’approche hybride de la valeur. Ce modèle vise à décrire la création d’une valeur globale résultant de l’usage d’une application mobile d’aide à l’achat et à identifier l’impact de cette valeur globale sur la fidélité. Ce modèle est testé par le biais d’une méthodologie expérimentale pour laquelle des applications fictives ont été spécialement conçues. Cinq études quantitatives successives sont menées sur un échantillon global de plus 1000 étudiants. Des analyses multi-groupes permettent de mesurer les effets modérateurs des éléments conditionnels : Les résultats montrent que la valeur globale induite par l’usage de ces applications mobiles influence la fidélité envers le point de vente. Chacun des éléments conditionnels présente des effets modérateurs sur les liens du modèle. Les effets modérateurs du type d’application « Push » combinés au fort degré de personnalisation obtiennent les meilleurs résultats avec la création d’une valeur globale conséquente impactant la fidélité envers le point de vente<br>The breakthrough of mobile shopping applications is a recent phenomenon. The increasing use of smartphones in retail stores (i.e. more than 70% of consumers) has led retailers to develop these tools to help consumers make smarter purchases. However, similar to Self-service technologies (e.g. automatic cash registers), mobile applications raise many issues, particularly regarding the factors that create customer value. The objective of our research is therefore to measure the value of a mobile purchasing support application for the customer in the context of a retail store. It also involves determining the consequences on the relationship with the retail store. This work is based on the literature on the concept of value and on mobile purchasing assistance applications. Qualitative exploratory research in the form of focus groups highlights the benefits and costs associated with the use of mobile applications in the retail store. Various conditional elements that can moderate the link effects of these applications are also identified: type of retail store (food versus multimedia), type of application ("Pull" versus "Push") and level of personalization (personalized versus non-personalized). This leads us to the construction of a scale for measuring the value in use of an application and to the development of a conceptual model that incorporates the hybrid approach of value. This model aims to describe the creation of global value resulting from the use of a mobile purchasing assistance application and to identify the impact of this global value on loyalty. This model is tested using an experimental methodology for which fictive applications have been specially designed. Five successive quantitative studies are conducted on a total sample of more than 1000 students. Multigroup analysis are used to measure the moderating effects of conditional elements: The results show that the global value induced by the use of these mobile applications influences loyalty to the point of sale. Each of the conditional elements has moderating effects on the model links. The moderating effects of the "Push" application type combined with the high level of personalization achieve the best results with the creation of a significant global value impacting loyalty to the point of sale

ObjectifLe diagnostic prénatal (DPN) a pour but de détecter des pathologies foetales in utero. L’objectif de ce travail était de mettre au point et d’appliquer les techniques d’exploration chromosomique en prénatal. Nous avons, tout d’abord, validé et évalué une plateforme de séquençage basée sur la technologie des semi-conducteurs, Ion Proton®, pour le dépistage prénatal non-invasif (DPNI) des principales aneuploïdies en routine clinique, puis évalué l’intérêt de l’Analyse Chromosomique sur Puces à ADN (ACPA) dans le diagnostic prénatal des retards de croissance intra-utérin (RCIU) foetaux. Matériel et Méthodes Nous avons inclus prospectivement 2505 patientes enceintes analysées par huit laboratoires hospitalo-universitaires de génétique : 695 grossesses à haut risque pour la trisomie 21 (risque ≥1/250 ou avec anomalie échographique) dans une étude de validation de la technique du test ADN libre circulant (ADNlc), et 1810 grossesses à risque, sans anomalie échographique, en routine clinique. Les issues de grossesses étaient toutes disponibles dans l’étude de validation et pour 521 grossesses dans l’étude en routine clinique. L’ADNlc extrait d’échantillons plasmatiques était séquencé, puis les données étaient analysées à l’aide du logiciel WISECONDOR. Les résultats des tests ADNlc étaient comparés aux caryotypes foetaux ou 7 aux données à la naissance. Nous avons aussi évalué le taux d’échec et comparé trois méthodes d’évaluation de la fraction foetale (FF) (RASSF1A, DEFRAG et SANEFALCON). Nous avons rétrospectivement inclus tous les foetus référés pour un prélèvement invasif pour RCIU et étudié les résultats de technique d’hybridation in situ en fluorescence (FISH), caryotypes et ACPA. Résultats Les résultats des deux cohortes de l’étude sur l’ADNlc étaient cohérents et les âges gestationnels n’étaient pas significativement différents ; les données ont été combinées afin d’étoffer la cohorte à analyser. Respectivement, la sensibilité et la spécificité étaient de : 98.3% (95% IC, 93.5–99.7%) et 99.9% (95% IC, 99.4–100%) pour la trisomie 21; 96.7% (95% IC, 80.9–99.8%) et 100% (95% IC, 99.6–100%) pour la trisomie 18 ; et 94.1% (95% IC, 69.2–99.7%) et 100% (95% IC, 99.6–100%) pour la trisomie 13. Le taux de non rendus était de 1.2% initialement puis après réanalyse de 0.6%. L’estimation de la FF avec les méthodes RASSF1A et DEFRAG étaient comparables, toutes deux compatibles avec une utilisation en routine clinique. Parmi les 162 foetus RCIU (78 associés et 84 isolés) inclus dans l’étude ACPA, 15 avaient une FISH pathologique : 10 RCIU associés et cinq RCIU isolés. Parmi 143 foetus étudiés par ACPA, 10 (7%) présentaient un variant du nombre de copies (CNV), tous étaient des RCIUs associés (10/65 soit 15.4%; 95 IC: 8.4%‐26.2%), versus 0/78 dans le groupe RCIUs isolés (95% IC: 0%‐5.6%). Six foetus (4.2%) ont présenté des variants de signification inconnue (VSI) (trois RCIU associés et trois RCIU isolés). Conclusion : Notre étude évaluant le test ADNlc utilisant la technologie des semi-conducteurs est la première étude clinique à rapporter les issues de grossesses dans une population aussi large. La plateforme est performante pour le DPNI des principales aneuploïdies. Notre protocole robuste est facilement applicable en routine clinique. Notre étude souligne une augmentation de rendement diagnostique de l’ACPA de 6.1% (4/65) par rapport au caryotype pour le DPN des foetus présentant un RCIU associé. Aucun CNV pathogène n’a été mis en évidence dans le groupe RCIU isolé. L’ADNlc pourrait-il supplanter l’ACPA dans cette population de RCIU isolé ? Le développement du test ADNlc a permis de limiter le nombre de prélèvements invasifs et donc leurs complications [...]<br>ObjectivePrenatal diagnosis allows to detect fetal pathologies in-utero. The goal of this work was both technical development and application of the chromosomal exploration technics in prenatal diagnosis. First, we aimed to validate and evaluate the performance metrics of the highthroughput semiconductor sequencing platform, Ion Proton®, in non-invasive prenatal genetic screening (NIPS) for common fetal aneuploidies in a clinical setting and, then to evaluate the diagnostic utility of prenatal diagnosis using the chromosomal microarray analysis (CMA) for fetuses presenting with isolated or associated intrauterine growth restriction (IUGR). Methods : First, regarding NIPS, a prospective cohort study including 2505 pregnant women from eight academic genetics laboratories (695 high risk pregnancies for trisomy 21 (risk ≥1/250 or with ultrasound anomalies) in a validation study, and 1810 such pregnancies, without ultrasound anomalies, in a real-life NIPS clinical setting) was conducted. An outcome was available for all cases in the validation cohort and for 521 in the clinical cohort. Cell-free DNA from plasma samples was sequenced using the Ion Proton sequencer, and sequencing data were analyzed using the open-access software, WISECONDOR. Performance metrics for detection 10 of trisomies 21, 18 and 13 were calculated based on either fetal karyotype result or clinical data collected at birth. We also evaluated the failure rate and compared three methods of fetal fraction quantification (RASSF1A assay, and DEFRAG and SANEFALCON software). Then, regarding the CMA study, we retrospectively included all fetuses with IUGR referred for prenatal testing and studied by rapid fluorescence in situ hybridization (FISH), karyotype, and CMA. Results :In the NIPS study, results from both cohorts were consistent and their gestational age was not significantly different, so their data were combined to increase the sample size for analysis. Sensitivities and specificities, respectively, were as follows: for trisomy 21, 98.3% (95% CI, 93.5–99.7%) and 99.9% (95% CI, 99.4–100%); for trisomy 18, 96.7% (95% CI, 80.9–99.8%) and 100% (95% CI, 99.6–100%); and for trisomy 13, 94.1% (95% CI, 69.2–99.7%) and 100% (95% CI, 99.6–100%). Our failure rate was 1.2% initially and as low as 0.6% after retesting some of the failed samples. Fetal fraction estimation by the RASSF1A assay was consistent with DEFRAG results, and both were adequate for routine diagnosis. Among the 162 IUGR fetuses (78 associated and 84 isolated IUGR) included in the CMA study, 15 had an abnormal FISH result: 10 associated and five isolated fetal IUGRs. Among the 143 fetuses studied by CMA, 10 (7%) presented pathogenic copy number variations (CNVs). All 10 were in the associated fetal IUGR group (10/65 or 15.4%; 95% confidence interval [CI]: 8.4%‐26.2%) versus 0/78 in the isolated fetal IUGR group (95% CI: 0%‐5.6%). Six fetuses (4.2%) carried variants of unknown significance (VOUS) (three associated and three isolated fetal IUGRs). Conclusion: We described one of the largest studies evaluating Ion Proton-based NIPS and the first clinical study reporting pregnancy outcome in a large series of patients. This platform is highly efficient in detecting the three most common trisomies. Our protocol is robust and can be implemented easily in any medical genetics’ laboratory. Our second study highlighted the added value of CMA in the case of associated fetal IUGR with an incremental yield of 6.1% (4/65) over karyotyping. No pathogenic CNVs were reported in the isolated fetal IUGR group. Could NIPS supplant CMA in isolated fetal IUGR? The development of the NIPS test has reduced prenatal invasive testing and therefore its complications [...]

Previous issue date: 2017-03-29<br>The store environmental factors and their influences on consumption are current and relevant themes, dealt with by much of the academic literature. These factors, divided into auditory, visual, olfactory, tactile, tasteful and social, are presented as the focus of managerial strategies, do to the interferences in the dynamics of attention at the point of sale. This paper seeks to clarify this dynamic, in face of three factors: auditory, visual and social. For that, the variables of music, lighting and crowding and their influences on consumer attention in a simulated supermarket environment were considered. The analysis was carried out in the Retail Lab of the School of Advertising and Marketing with the use of EyeTracking technology to identify the visual attention in front of six varied scenarios. The results point to a positive impact of music of moderate height (ambient sound), as well as influences of the high and natural lighting and acceleration of the decisions of purchase by the density of individuals (crowding). Such results contribute to the academic and managerial knowledge in marketing, with indication of proposals for future studies.<br>Os fatores ambientais de loja, e suas influências sobre o consumo são temas atuais e relevantes,

Previous issue date: 2013-10-24<br>Given this cyber revolution formed by a discharge of digital content and different formats of media and advertising, generation Z emerges, breaking the traditional model of consumption to a more interactive and dynamic whose main vectors are formed by connectivity and sharing experience. On the other hand, the retailers are remaining with the traditional model bringing a limited and offline experienre, promoting a dichotomy between the potential consumers seeking an exclusive and fun experience. The following study seeks to understand the qualities, features and aspirations of this new consumer experience at the point of sale in order to present the main challenges and changes needed to attract this demanding consumer member of Generation Z. The study includes a survey at the point of sale and interviews to understand how this generation realizes the point of sale. The research reveals that these children are seeking a more interactive and dynamic environment at the point of sale and the retail must change to attend this new generation<br>Diante da revolução cibernética formada por grande quantidade de conteúdos digitais e formatos diferenciados de mídia e propaganda, a Geração Z surge rompendo o modelo tradicional de consumo e caminha para um modelo mais interativo e dinâmico, cujos principais vetores são formados por conectividade, compartilhamento e experiência. Do outro lado do cenário encontra-se o varejo, que insiste no modelo tradicional cuja experiência permanece limitada e estática, promovendo uma dicotomia entre esta prática e o público potencial consumidor da Geração Z, que busca uma experiência exclusiva e entretenimento. Este estudo busca entender as qualidades, anseios e características desse novo consumidor frente à experiência de consumo no ponto de venda, visando apresentar os principais desafios e adequações para atrair o consumidor exigente membro da Geração Z. O presente trabalho contempla uma pesquisa no ponto de venda e entrevistas em profundidade para entender como esta geração percebe o ponto de venda. A pesquisa revela que estas crianças buscam uma experiência mais interativa e dinâmica e o varejo tradicional terá que mudar para se adequar a este geração

La recherche sur les pointes à fabriquer a commencé par une analyse du produit suivie d'une étude bibliographique. Le présent rapport ne relate pas les différents essais menés sur le choix entre câble acrylique et ruban acrylique ou encore le choix de la résine. La conception du procédé de chauffage a nécessité une étude théorique sur les cavités micro-ondes suivie de la construction de deux cavités micro-ondes monomodes dont une n'a pas donné de résultats encourageants (TM 010). La deuxième (TM 014) fonctionne avec un rendement élevé mais ne permet pas la cuisson totale du jonc composite, c'est pourquoi il a fallu imaginer un four tunnel adapté. La dernière partie de la recherche a consisté à concevoir une ligne de fabrication de pointes de marqueur incluant cavité micro-ondes et tunnel de cuisson. Le résultat de ce travail est la mise en place d'une ligne de fabrication de pointes plus simple que celle connue au Japon et amenant des produits finaux aussi performants à des prix nettement inférieurs, c'est-à-dire que la société a réussi à se séparer d'un monopole japonais existant depuis une trentaine d'années.

Full textAbstract:
L'objectif principal de cette étude expérimentale est de mieux comprendre et de caractériser le phénomène de retrait et le comportement de fissuration de l'argile pendant le séchage, et de mieux appréhender le mécanisme d'initiation et de propagation des fissures dans l'argile sous sollicitation hydrique. Le kaolin K13, qui est une argile kaolinite pure, a été considéré dans notre étude. La recherche est consacrée à deux parties principales, l'une concernant le retrait dû au séchage et l'autre la fissuration hydrique. Des études expérimentales sur le retrait dû au séchage sont menées pour déterminer les propriétés hydriques et le comportement mécanique du matériau étudié pendant le processus de dessiccation. Pour cela, les paramètres hydriques d'argile non saturée ayant différents niveaux de succion ont été mesurés par les essais au kerdane. L'essai est basé sur la mesure du volume solide d'un échantillon par déplacement liquide. La courbe de retrait et la courbe de rétention d’eau du matériau étudié ont été établies après ajustement des formules de Fredlund et de Van Genuchten à partir des résultats expérimentaux. Les déformations globales et locales de sont obtenues par le CIN-2D et CIN-3D. En fin, la teneur en eau locale et la succion locale de l'échantillon sont estimées à partir de la déformation volumique locale couplée à la courbe rétention eau et à la courbe de retrait du notre matériau. La deuxième partie de l'étude est consacrée à l'initiation et à la propagation des fissures sous dessiccation contrôlée d’une argile initialement saturé. Afin d’étudier les principaux facteurs influençant la fissuration et de comparer avec le retrait libre, le support semi-rugueux a été utilisé dans des essais de dessiccation contrôlé, de sorte que les fissures produites dans les différents échantillons ont été capturées par la CIN. Le développement des fissures a d'abord été quantifié par des études morphologiques et statistiques des fissures via logiciel Image-J. L’influence du chemin de séchage et du support de l’échantillon sur le comportement de la fissuration hydrique ont également été étudiés à échelle globale d’échantillon par la CIN. L'augmentation de la déformation mécanique au sein de l'échantillon, produite par l'effet de limitation du support sur la déformation de retrait, est l'une des principales causes de fissuration. La distribution des déformations locales, le phénomène de concentration des contraintes (à travers le développement des déformation locales), sont étudiées et analysées. Les fissures sont amorcées dans des zones de tension locales où la limite de traction du sol est dépassée. Le comportement de propagation de la fissuration est dû à la zone de contrainte en traction à la pointe de la fissure. Le mécanisme de fissuration est défini par l'étude de la direction principale de déformation. Les fissures observées se sont développées dans la direction horizontale des échantillons, avec peu d'effet de la déformation verticale sur leur apparition. Le mode de rupture est principalement du mode I. Des modes de rupture plus complexes, mixtes avec le mode I, existent également. L'étude du mécanisme de fissuration, notamment des fissures provoquées par la traction (mode I) a été approfondie par des essais de traction indirecte sur les poutrelles d'argile. Des poutres ayant différents niveaux de succion ont été soumises à une flexion à trois points, ce qui a provoqué des fissures de traction dans leur partie inférieure tendu. La résistance maximale et la flexion maximale à la fissuration et la déformation locale en traction liée à la fissuration sont étudiées, ainsi que l'effet de la succion sur la résistance des argiles non saturés<br>The main objective of this experimental study is to better understand and characterize the shrinkage phenomenon and the cracking behavior of clay during drying, and to better understand the mechanism of crack initiation and propagation in clay under hydric loading. Kaolin K13, which is a pure kaolinite clay, was considered in our study. The research is devoted to two main parts, one related to drying shrinkage and the other to desiccation cracking.Experimental studies on drying shrinkage are conducted to determine the hydraulic properties and mechanical behavior of the studied material during the drying process. For this purpose, the hydric parameters including water content, void index and degree of saturation of small unsaturated clay samples with different suction levels were measured by the Kerdane tests. The test is based on measuring the solid volume by liquid displacement. The shrinkage curve and the water retention curve of the studied material were established after fitting the Fredlund and Van Genuchten formulas from the experimental results. The shrinkage deformation of the soil was studied by controlled desiccation tests using smooth supports. Controlled desiccation, using the salt solution method, allows samples to be subjected to the same desiccation path. Global and local deformations of are obtained by 2D-DIC and 3D-DIC. Finally, the local water content and the local suction of the sample are estimated from the local volume deformation coupled with the water retention curve and the shrinkage curve of our material.The second part of the study is devoted to the initiation and propagation of cracks under controlled desiccation of an initially saturated clay. In order to study the main factors influencing cracking and to compare with free shrinkage, the semi-rough substrate was used in controlled desiccation tests, so that the cracks produced in the different samples were captured by the DIC. The evolution of the cracks was first quantified by morphological and statistical studies of the cracks via Image-J software. The influence of the drying path and sample support on the water cracking behavior were also studied at the global sample scale by the DIC. The increase in mechanical strain within the sample, produced by the limiting effect of the support on shrinkage deformation, is one of the main causes of cracking. The distribution of local strains, the phenomenon of stress concentration (through the development of local strains), are studied and analyzed. Crack initiation occurs in local stress zones where the tensile limit of the soil is exceeded. The crack propagation behavior is due to the tensile stress zone at the crack tip. The cracking mechanism is defined by studying the principal direction of deformation. The observed cracks developed in the horizontal direction of the samples, with little effect of vertical deformation on their occurrence. The mode of failure is mainly mode I. More complex failure modes, mixed with mode I, also exist. The study of the cracking mechanism, especially the cracks caused by traction (mode I) was further investigated by indirect traction tests on clay beams. Beams with different levels of suction were subjected to three-point bending, which caused tensile cracks in their tensioned lower part. The maximum strength and maximum bending at cracking and the local tensile deformation related to cracking are studied, as well as the effect of suction on the strength of unsaturated clays

Full textAbstract:
La sécheresse géotechnique est à l'origine de nombreux désordres urbains dans la régio n d'Ile-de-France. La présence d'argiles continentales Eocène-Oligocène aux propriétés gonflantes parmi les dépôts actuels les plus récents de la série géologique du Bassin Parisien entraîne, sous l'influence des contrastes climatiques liés à des évènements climatiques " extrêmes " (alternances sécheresse et période humide) des variations importantes du volume des sols. Les variations sont susceptibles d'induire des déplacements de la surface du sol qui affecte le bâti. Deux méthodes d'interférométrie radar y sont appliquées afin de suivre ces déplacements relatifs au cours du temps : si la méthode différentielle (DINSAR), qui permet de mesurer les déplacements de la surface du sol à partir de deux images radar acquises à des dates différentes se révèle peu performante sur l'Est du Bassin de Paris devant la faible cohérence de l'habitat pavillonnaire individuel, la seconde méthode, la technique de suivi des réflecteurs permanents, appelé Persistant Scatterer Interferometry ( PSI) permet de décrire précisément dans le temps les déplacements absolus de points à forte rétrodiffusion radar par la localisation, la caractérisation et la quantification des déplacements de la surface du sol à partir d'un grand nombre d'images radar à ouverture de synthèse (RSO). Des déformations liées au RGA observées sur les profils de pavillons sinistrés ont été mise en évidence et corrélé avec les périodes de sécheresse. Cette méthode présente un fort potentiel pour l'étude du risque naturel sécheresse géotechnique tout particulièrement sur l'Est du Bassin de Paris affecté lors des dernières périodes de sécheresses dans un contexte de changement climatique mondiale

Full textAbstract:
In questa tesi si propone una nuova strategia di deep learning per affrontare il problema del deblurring applicato a immagini digitali. Quest’ultimo è un problema inverso noto che viene solitamente riformulato come problema di ottimizzazione regolarizzata, in cui, la funzione obiettivo da minimizzare è data dalla somma di un termine di data-fidelity e di un termine di regolarizzazione. Inoltre, è possibile imporre dei vincoli sulla funzione obiettivo, che permettono di integrare conoscenze a priori sulla soluzione desiderata.
In questo lavoro, si considerano termini di data-fidelity e di regolarizzazione differenziabili e si includono vincoli di tipo box sulla funzione obiettivo, attraverso l'uso di una funzione di barriera logaritmica.
Nel nostro caso, viene adottato un metodo interior point (IPM) per affrontare il processo di minimizzazione, in cui il proximity operator è applicato alla sola funzione di barriera. La peculiarità dell’approccio proposto sta nel fatto che il parametro di regolarizzazione, il parametro di barriera e la lunghezza di passo necessari all’applicazione del metodo IPM sono scelti mediante una particolare strategia di deep learning. In particolare, i passi dell’algoritmo IPM vengono incorporati in una rete neurale, il cui processo di training si fonde con il processo di ottimizzazione.
Per fare il training e testare la rete neurale risultante si è utilizzato un dataset di immagini naturali ben noto in letteratura. In particolare ci si è confrontati con metodi standard di proiezione del gradiente, con recenti algoritmi di machine learning e con altri unfolded methods. In conclusione, i test mostrano come l’approccio proposto abbia buone prestazioni e sia competitivo rispetto allo stato dell’arte.<br>The aim of this thesis is to propose novel Deep Learning model to approach the image deblurring problem.
This is a well known Inverse Problem that is usually reformulated as a regularized optimization problem, in which the objective function to be minimized is a sum of a data discrepancy measure with a regularization term. Also additional constraints can be imposed to incorporate a priori knowledge on the desired solution.
In our work we consider smooth data-fidelity and regularization terms and we include constraints in the objective function by means of a logarithmic barrier.
A proximal interior point method (IPM) is adopted to address the minimization step, in which the proximity operator is restricted only to the barrier function. The key issue of our proposed approach is the following: the regularization parameter, the barrier parameter and the step size needed in the iterations of the IPM are chosen by means of a particular Deep Learning strategy. In particular, we say that the IPM algorithm is unfolded in a neural network structure, whose training process merges with the optimization process.
We used benchmarks image datasets to train the resulting neural network architecture and test our approach. Comparisons with standard gradient projection methods, with recent machine learning algorithms and also with other unfolded methods have been performed and the tests showed good performances and competitiveness of our approach.

This thesis collects the key research results on wireless networking developed during the three years of the PhD. The approach that underlies all work has been the analysis and design of wireless network protocols together with their physical layer. The former have been created keeping in mind the features of the adopted physical layer techniques and, conversely, the physical layer has been chosen according to the employed MAC/routing and its necessities. The results focus on three main areas.
In the first branch, MIMO signal processing is applied in order to optimize broadcast in a wireless MIMO network, to improve the robustness of Network Coding to the vagaries of the wireless environment and finally to design cooperative protocols that reward nodes which help each other. In all these cases, great emphasis has been placed on signal processing and on its actual algorithmic implementation.
In the second part, Carrier Sense optimization for radio networks is studied. First a special type of carrier sense system for MIMO ad hoc networks is described. Then, attention is focused on single antenna terminals, and an analytical model for carrier sense optimization in static networks (i.e., topology is known) is developed so as to find the carrier sense threshold that maximizes aggregate throughput. Moreover, specific algorithms have been created also for dynamic networks (i.e., nodes are mobile or the topology is not known beforehand). In addition, the analytical model for static networks is applied also to design a low-complexity, high-performance scheduler for mesh networks. In any case, interference analysis and the characteristics of the propagation environment play a key role to study this problem.
In the last portion of this thesis, a more theoretical approach is undertaken: the performance of an Aloha multihop wireless network in terms of throughput and delay is analyzed, under saturation conditions or not. The impact of a variety of physical layer parameters (like rate, path-loss exponent or SNR decoding threshold) on network performance is analyzed, and we establish how certain parameters (e.g., transmission probability, rate, route length, admission control) must be tuned in order to optimize performance.

Full textAbstract:
Le retard de croissance intra-utérin (RCIU) est une complication responsable d’une importante mortalité et morbidité périnatales. Son dépistage représente un enjeu important de la surveillance prénatale. Les objectifs de la thèse étaient d’évaluer la performance du dépistage anténatal du RCIU, d’identifier ses déterminants et de mesurer son impact sur les issues périnatales. Dans une première partie, nous avons utilisé les données de l’Enquête Nationale Périnatale de 2010 (N=14 100 enfants uniques) : 21,7% des enfants de poids <10ème percentile étaient suspectés avec un RCIU en anténatal tandis que la moitié des enfants suspectés avait un poids normal à la naissance (faux positifs). Le risque de naissance induite était élevé en cas de suspicion, indépendamment de l’existence d’un faible poids, suggérant des interventions iatrogènes. Les issues néonatales n’étaient pas différentes selon la suspicion. Dans une seconde partie, nous avons utilisé les données d’une cohorte nationale d’enfants nés avant 32 SA en 2011, EPIPAGE 2 (N=3698 enfants uniques sans anomalie congénitale). La prise en charge active pour indication fœtale en cas de RCIU était initiée à partir de 26 SA. Pour 14% des enfants, il existait une discordance entre la suspicion d’un RCIU en anténatal et un faible poids à la naissance. En cas de discordance, le poids de naissance était le paramètre le plus important pour évaluer le pronostic néonatal. Nos travaux soulèvent des questions sur l’efficacité du dépistage du RCIU en France. Ils montrent la nécessité de développer de nouvelles stratégies de dépistage et de poursuivre les recherches pour mesurer leur impact sur les décisions médicales et sur la santé<br>Fetal growth restriction (FGR) is a pregnancy complication that is responsible for significant perinatal mortality and morbidity. Screening for FGR is a key component of prenatal care. The objectives of this thesis were to evaluate the performance of prenatal screening for FGR, to identify the determinants of antenatal suspicion of FGR and to measure its impact on perinatal outcomes. For the first part of the thesis, we used data from the nationally representative French National Perinatal Survey of births (N=14,100 singleton pregnancies): 21.7% of infants with a low birthweight <10th percentile were suspected with FGR during pregnancy and half of infants suspected with FGR had a normal birthweight (false positives). The risk of indicated delivery was higher when FGR was suspected, regardless of the existence of low birthweight, suggesting possible iatrogenic effects. Outcomes were not different for suspected versus unsuspected low birthweight infants. In the second part of the thesis, we used data from the EPIPAGE 2 national cohort of children born before 32 weeks of GA in 2011 (N=3698 singleton non-anomalous infants). Active management for fetal indications in cases of suspected FGR was initiated at 26 weeks. Antenatal and postnatal assessments of FGR were discordant for 14% of infants. When assessments were discordant, birthweight was a better predictor of adverse neonatal outcome. Our results raise questions about the effectiveness of screening strategies for FGR in France. New strategies for the detection of FGR are needed as well as research to measure the impact of screening on medical decisions and health

Full textAbstract:
Si on sait que les mensurations de naissance et la croissance postnatale précoce sont liés au développement à long terme de maladies métaboliques, les mécanismes de cette liaison ne sont pas précisément compris. Cette association passerait par la mise en place précoce dans la vie d'une insulinorésistance conditionnée par la maigreur à la naissance ainsi que par l'intensité du gain de masse grasse lors de la croissance de rattrapage postnatal. Dans une cohorte prospective d'enfants inclus dès la vie fœtale nous avons mesuré les profils de croissance fœtale, puis la croissance postnatale, ainsi que les modifications de la composition corporelle et du statut hormonal. La restriction de croissance fœtale (RCF) va entrainer à la des modifications de la composition corporelle accompagnées de modifications métaboliques ayant pour but de favoriser la survie de l'organisme. Pendant les premiers mois de vie, les enfants ayant présenté une RCF vont présenter une croissance accélérée permettant une restauration de la masse maigre et de la masse grasse dès le quatrième mois de vie, sans entrainer de modifications de la sensibilité à l'insuline. Nos résultats suggèrent que la croissance de rattrapage est un phénomène endogène précoce et non délétère, favorisée par les adaptations du métabolisme développées in utero, et ayant pour but de restaurer la composition corporelle des nourrissons. L'excès de masse grasse et l'insulinorésistance décrites chez les sujets nés avec de petites mensurations de naissance apparaîtraient donc plus tard dans la vie, probablement favorisée par l'interaction entre les modifications persistantes du métabolisme et un environnement nutritionnel déséquilibré<br>Fetal growth restriction (FGR) followed by rapid weight gain during early postnatal life has been suggested to be a sequence leading to an increased risk of metabolic disease. Anyway early growth and associated changes in body composition or metabolic statue has never been studied in a prospective way. Furthermore, birth weight (BW) is usually taken as a surrogate of fetal growth. However, B W per se is not relevant enough in assessing fetal growth restriction, which by itself may alter body composition, metabolic and hormonal profiles at birth (irrespective of BW) reflecting the necessary adaptive changes in metabolism under poor fetal environment. In a cohort of newborns in whom fetal growth velocity had been recorded in a prospective and standardized manner, we report that, independently from birth weight, fetal growth restriction by itself is able to induce changes in body composition characterized by a lower fat mass and changes in metabolism with a higher insulin sensitivity reflecting adaptive changes to an adverse fetal nutritional environment. The pattern of postnatal growth over the first year of life with respect of fetal growth velocity and the simultaneous changes in body composition and metabolism were then studied. We report that catch-up growth is related to fetal growth pattern regardless birth weight. This catch-up seems to be an intrinsic phenomenon occurring in the first months of life in order to restore the lower fat mass but without deleterious consequences neither on its repartition nor in its quantity

Full textAbstract:
Le Syndrome de Down, aneuploïdie la plus courante, a pour cause première la présence d'un chromosome 21 surnuméraire. L'établissement de cartes de corrélation génotypes/phénotypes chez les patients atteints du Syndrome de Down a permis de mettre en évidence la kinase DYRK1A, codée par le gène DYRK1A localisé dans la région DCR-1 du chromosome 21, comme candidat pouvant être impliqué dans l'apparition d'un retard mental. Comprendre le rôle et la régulation de DYRK1A est donc essentiel et pour cela, utiliser un test fiable de mesure d'activité de l'enzyme est indispensable. Nous avons développé une nouvelle méthode de dosage de l'activité kinase de DYRK1A utilisant la chromatographie en phase liquide à haute performance (HPLC). Cette méthode s'est révélée très sensible et peu coûteuse. En utilisant cette nouvelle méthode, nous avons confirmé les principales données obtenues in vitro sur l'activité de DYRK1A. Nous avons également caractérisé le comportement d'inhibiteurs connus de DYRK1A (harmine) et confirmé les résultats rapportés dans la littérature. En collaboration avec l'équipe du Dr. Dodd nous avons criblé des dérivés hétérocycliques azotés de faible poids moléculaire, inhibiteurs potentiels de DYRK1A. Enfin, le test d'activité a été utilisé ex vivo sur des extraits de cerveau de souris. Nos résultats indiquent que cette nouvelle méthode de dosage d'activité kinase est spécifique, reproductible et rapide. Elle peut potentiellement s'appliquer à d'autres kinases, phosphatases et plus largement à d'autres enzymes catalysant une réaction de modification de protéines. La GnRH joue un rôle essentiel en régulant la sécrétion et la synthèse de LH et de FSH via des récepteurs spécifiques (GnRHR) exprimés à la surface des cellules gonadotropes hypophysaires. L'expression tissulaire spécifique du Gnrhr est contrôlée par une combinatoire bien définie de facteurs de transcription comportant trois acteurs majeurs, SF1, LHX3 et ISL1. Au contraire du Gnrhr, nous montrons que les séquences régulatrices d'Isl1 en amont du site d'initiation de transcription (TSS) sont insuffisantes pour diriger l'expression hypophysaire spécifique, suggérant l'existence de mécanismes additionnels. De fait, les régions régulatrices (ou promoteurs) ainsi que les "corps" des gènes sont altérés par des modifications épigénétiques. Les résultats, obtenus par immunoprécipitation de la chromatine, montrent que dans les lignées cellulaires exprimant Isl1, notamment les cellules gonadotropes, Isl1 est complexé avec des histones H3 triméthylées sur la Lys4 (H3K4Me3) au niveau du TSS, une marque d'histones corrélée avec les gènes actifs. En revanche, dans les lignées cellulaires où Isl1 est silencieux, il est complexé avec des histones H3 triméthylées sur la Lys27, marque liée à la répression des gènes. On observe cette même corrélation au niveau du TSS du Gnrhr. De plus, notre étude suggère que la méthylation de l'ADN, en amont de l'îlot CpG est inversement corrélée à l'activité de ce gène. Ces données suggèrent que les modifications épigénétiques sont essentiellement responsables de l'expression hypophysaire spécifique d'Isl1contrairement à l'expression du Gnrhr qui semble principalement dépendante de la présence de facteurs de transcription tissulaires spécifiques majeurs. Mots clefs : ISL1, récepteur du GnRH, antéhypophyse, régulation épigénétiques, modifications des histones, méthylation de l'ADN, protéine LIM à homéodomaine, cellules gonadotropes.

Les prévalences de FPN, de prématurité et de RCIU dans notre population d’étude étaient de 9,1%, 10,3% et 25,3% respectivement. La majorité des enfants nés avec un FPN (75%) avaient un RCIU. Concernant la prématurité, seul le sexe de l’enfant était associé à un risque plus faible. A l’inverse, les garçons étaient plus à risque de RCIU. Les mères primipares et celles ayant un faible statut anthropométrique avaient une plus grande probabilité de donner naissance à des enfants en FPN et ceci s’exprimait principalement par le mécanisme RCIU. La même analyse sur le poids de naissance en quantitatif a donné des résultats similaires et a montré en plus un effet négatif indépendant de la petite taille de la mère (<155cm). Nous n’avons pas retrouvé d’effet de l’infection placentaire palustre ni de l’anémie maternelle. Les enfants nés avec un FPN, ceux ayant vécu un RCIU et ceux issus de mère en déficit nutritionnel présentaient un retard de croissance linéaire. Nous avons aussi mis en évidence que le FPN et le faible statut anthropométrique de la mère avaient un lien significatif avec la maigreur. La morbidité palustre n’était pas associée à l’évolution staturo-pondérale. Les bonnes pratiques alimentaires, objectivées par un bon score IYCF s’accompagnaient d’une corpulence correcte, alors qu’elles étaient associées de manière paradoxale à un retard de croissance linéaire. Le déficit nutritionnel maternel (faible statut anthropométrique ou petite taille) est impliqué dans la survenue du FPN mais est également responsable par un effet propre d’une mauvaise croissance staturo-pondérale. Nos résultats confirment bien l’existence d’un cycle intergénérationnel de la malnutrition<br>The prevalence of low birth weight, preterm birth and IUGR in our study population were 9.1%, 10.3% and 25.3% respectively. The majority of children born with LBW (75%) had IUGR. Concerning prematurity, only the sex of the child was associated with a lower risk. Conversely, boys were more at risk of IUGR. Primiparous and those with low anthropometric status were more likely to give birth to children with LBW and this was expressed mainly by IUGR mechanism. The same analysis on birth weight as continuous variable gave similar results and showed in addition, an independent negative effect of maternal short stature (<155cm). We did not find an effect of placental malaria infection or maternal anemia. Children born with LBW, IUGR and those from mother with nutritional deficiency showed a linear growth retardation. We also demonstrated that LBW and low anthropometric status of the mother were significantly correlated with leanness. Malaria morbidity was not associated with growth. Good feeding practices objectified by a good IYCF score, were accompanied by a proper corpulence, while they were paradoxically associated with a linear growth delay. Maternal nutritional deficiency (low anthropometric status or short stature) is involved in the occurrence of LBW but also impacted negatively children’s growth through an independent effect. Our results confirm the existence of an intergenerational cycle of malnutrition

Duong, Phuoc Tra My <1991>. "WHAT MAKES OPPO SUCCEED IN THE VIETNAM MARKET? Background of the study Vietnam has become an emerging country and attractive retail market in the globe (Deloitte, 2014). Modern retail platform was introduced and have been blooming in Vietnam such as convenience stores, special stores and shopping centers (Trinh & Tran, 2014). The country is in the progress of transforming into digital economy, evidenced through high growth in electronic commerce and customer interaction through social network, etc. (Cameron et al., 2019). According to the Statista (2020), number of smartphone users in Vietnam was nearly 36 million in the end of 2019 and it is expected at 43 million by 2022. The growth in smartphone market was captured at 84% in 2017 and 95% of people in the cities have owned smartphone while the percentage of people with smartphone usage in rural area is reached up 68% (Nielsen, 2019). One of the attractive points in smartphone market is high population based with more than 94 million people (General Statistics Office, 2020). Vietnamese people spent more time reading news, playing games and conducting social interactions through social media network (Appota, 2018). These factors promote the entry of giant smartphone and electronic manufacturers such as Samsung and LG. Samsung has penetrated Vietnam for a long time and the Korean manufacturers established some factories in the country to enjoy lower tax rate and attractive labor cost (Sturgeon & Zylberberg, 2016)."

Rationales
Currently, Vietnamese people have variety of product choice in smartphone market. The survey conducted by Q&Me (2018) revealed top smartphone brands in Vietnam, including Apple, Samsung, Oppo, Xiaomi and Nokia, in which the first three smartphone brands have gained high brand recognition from the respondents. Key competitive advantage of Apple is luxurious and strong proud-to-have image while Samsung is positioned as a band of quality and design and Oppo is more famous in term of its camera features (Q&Me, 2018). However, Apple has not been setup its official store in Vietnam while Samsung and Oppo have been integrated this modern sales services in big cities and provinces and both of them gained reasonably high market share of more than 63% (Vietnam Insider, 2019). When comparing between Samsung and Oppo, the researcher identifies that Korean manufacturer made its entry to Vietnam since 2009 while Oppo, a Chinese smartphone manufacturer, have been entered the market since 2013. The gap is four year with advantage belonged to Samsung since it has established factories in the country. However, the market share between Samsung and Oppo is not so large. While Samsung consumed 38.44% of the market, Oppo was ranked in second place with 25.2% of the market share that turned Oppo to be second largest smartphone brand in Vietnam (Vietnam Insider, 2019). The question is how Oppo succeed in Vietnam has been raised after examining these figures or what the business model that is being adopted by Oppo to gain success in Vietnamese market. In addition, the researcher identifies that most of empirical evidences developed for Vietnam’s smartphone market focused on either consumer behavior in general (Wollenberg & Thuong, 2014) or consumer purchase and repurchase intention (Tran, 2018) or the role of mobile devices in retail industry (Dinh, 2017). There were no empirical evidences to explore the success of a smartphone manufacturer through their business model in the country. Thus, this study is developed under the urgent need of verifying business model of Oppo in order to identify its competitive advantages in comparison with other smartphone manufacturers.
Research objective and research questions
The study is developed with main objective of exploring the success of Oppo in Vietnam’s smartphone market. This research objective is supported following research questions:
• What are the opportunities and challenges in Vietnam’s smartphone market?
• How to address the success of Oppo in Vietnam’s smartphone market in comparison with other smartphone manufacturers through the analyses of components in Business Model Canvas?
• Which part of the smartphone manufacturers should take account to gain advantages in the Vietnam market?

Full textAbstract:
La sécheresse géotechnique est à l'origine de nombreux désordres urbains dans la régio n d'Ile-de-France. La présence d'argiles continentales Eocène-Oligocène aux propriétés gonflantes parmi les dépôts actuels les plus récents de la série géologique du Bassin Parisien entraîne, sous l'influence des contrastes climatiques liés à des évènements climatiques « extrêmes » (alternances sécheresse et période humide) des variations importantes du volume des sols. Les variations sont susceptibles d'induire des déplacements de la surface du sol qui affecte le bâti. Deux méthodes d'interférométrie radar y sont appliquées afin de suivre ces déplacements relatifs au cours du temps : si la méthode différentielle (DINSAR), qui permet de mesurer les déplacements de la surface du sol à partir de deux images radar acquises à des dates différentes se révèle peu performante sur l'Est du Bassin de Paris devant la faible cohérence de l'habitat pavillonnaire individuel, la seconde méthode, la technique de suivi des réflecteurs permanents, appelé Persistant Scatterer Interferometry ( PSI) permet de décrire précisément dans le temps les déplacements absolus de points à forte rétrodiffusion radar par la localisation, la caractérisation et la quantification des déplacements de la surface du sol à partir d'un grand nombre d'images radar à ouverture de synthèse (RSO). Des déformations liées au RGA observées sur les profils de pavillons sinistrés ont été mise en évidence et corrélé avec les périodes de sécheresse. Cette méthode présente un fort potentiel pour l'étude du risque naturel sécheresse géotechnique tout particulièrement sur l'Est du Bassin de Paris affecté lors des dernières périodes de sécheresses dans un contexte de changement climatique mondiale<br>Swelling soils may induce, under various climatic conditions such as drought or humid periods, surface displacements that affect small houses and buildings. The aim of this PhD work is to monitor through new interferometric methods those small displacements. Radar differential interferometry (DINSAR) method which enables one to map surface displacements from two radar images acquired on a specific area gives poor results in the east of the Paris Basin highly affected by the dryness hazards. It contrasts with Persistent Scatterer Interferometry (PSI) revealing precisely the seasonal behaviour of the displacements above swelling soils from a huge amount of radar images. Dryness events are correlated with swellings soils effects on damaged buildings thanks to the PSI profiles interpretation. This new application presents high potential to better understand the geologic processes and the natural hazard induced by swelling soils

Full textAbstract:
Contexte: Le retard de croissance intra-utérin (RCIU) désigne l’incapacité du fœtus à atteindre son potentiel de croissance déterminé génétiquement en raison de diverses causes. Il est défini le plus souvent par un poids de naissance inférieur au 10ème percentile pour l’âge gestationnel sur les courbes néonatales. Ce travail de thèse a comme objectif de répondre aux questions non-résolues sur la définition et les conséquences du RCIU dans le contexte de la grande prématurité: (1) Quelle est la meilleure définition du RCIU à utiliser pour identifier les enfants à risque ? (2) Quels sont les risques de mortalité et de morbidités néonatales respiratoires et neurologiques associés au RCIU et existe-t-il des interactions avec les pathologies de la grossesse responsables de cette naissance très prématurée ? (3) Quel est l’impact du RCIU sur le devenir neuro-développemental à 2 ans, en particulier chez les enfants nés extrêmement prématurément ? Méthodes: Nous avons utilisé deux sources de données. L’étude MOSAIC (Models for OrganiSing Access to Intensive Care for Very Preterm Babies in Europe) est une étude européenne en population qui porte sur l’ensemble des naissances survenues entre 22 et 31 semaines d’aménorrhée en 2003 dans dix régions européennes. Les enfants ont été suivis jusqu’à la sortie d’hospitalisation (population d’étude : 4525 enfants). La deuxième source est une cohorte d’enfants nés avant 27SA qui ont été hospitalisés dans le service de réanimation néonatale à l'hôpital de Port-Royal de 1999 à 2008 et qui ont eu un examen pédiatrique et une évaluation selon l’échelle de Brunet-Lézine qui inclut quatre domaines du développement global de l’enfant : la motricité globale, la motricité fine, le langage et l’interaction sociale (445 enfants admis, 268 enfants suivis à 2 ans). Résultats: Dans les deux populations, les risques de décès et de dysplasie broncho-pulmonaire étaient plus élevés pour les enfants ayant un poids de naissance <10éme percentile des courbes néonatales, mais également pour des enfants avec un poids plus élevé (entre le 10éme et le 24éme percentile des courbes néonatales ou <10ème percentile des courbes fœtales). Par contre, il n’y avait pas de lien entre les complications neurologiques et le faible poids, ni d’interaction avec les pathologies de la grossesse. Le RCIU était associé à un risque élevé du retard neurocognitif à deux ans d’âge corrigé chez les extrêmes prématurés, surtout dans le domaine de la motricité fine et de l’interaction sociale mais pas dans le domaine du langage et de la motricité globale. Nous n’avons pas trouvé d’association entre le RCIU et le risque d’infirmité motrice cérébrale à deux ans d’âge corrigé. Conclusions: L’utilisation du 10ème percentile des courbes néonatales n’est pas adaptée pour identifier l’impact du RCIU chez les grands prématurés ; l’utilisation de multiples seuils ou de courbes de croissance fœtale est nécessaire. Le RCIU accroit les risques de mortalité et de dysplasie broncho-pulmonaire, mais n’est pas associé aux lésions cérébrales sévères ; ces associations sont observées dans différents contextes périnatals (pathologies vasculaires et infectieuses, et naissances à des âges gestationnels très précoces). Le RCIU représente un facteur pronostic défavorable pour le neuro-développement à moyen terme. Nos résultats soulèvent de nouvelles questions sur le suivi adapté pour les enfants ayant un RCIU après leur sortie de l’hôpital et aussi sur les éventuels mécanismes biologiques pouvant expliquer les liens entre le RCIU avec une morbidité respiratoire et certains domaines du développement neurocognitif à moyen terme<br>Background: Intrauterine growth restriction (IUGR) refers to the inability of the fetus to achieve its genetically determined growth potential due to various causes. Most often, it is defined by a birth weight less than the 10th percentile for gestational age using neonatal growth curves. This thesis aims to answer unresolved questions about the definition and consequences of IUGR in the context of very preterm birth: (1) what is the best definition of IUGR for identifying children at risk? (2) What are the risks of mortality and neonatal respiratory and neurological morbidity associated with IUGR and are there interactions with the underlying pregnancy complications responsible for the very preterm birth? (3) What is the impact of IUGR on neurodevelopmental at 2 years, especially for children born extremely preterm ? Methods: We used two data sources. The MOSAIC study (Models for Organising Access to Intensive Care for Very Preterm Babies in Europe) is a European population-based study that included all births occurring between 22 and 31 weeks of gestation in 2003 in ten European regions. The children were followed until hospital discharge (study population = 4525 infants). The second source is a cohort of children born before 27 weeks of GA who were hospitalized in the neonatal intensive care unit at the Port Royal Hospital from 1999 to 2008 and had a pediatric examination and Brunet-Lézine (BL) neurodevelopmental assessment at 2 years of corrected age (445 children in the cohort, 268children followed at 2 years). The BL assessment includes four areas of child development: gross motor, fine motor, language and social interaction skills. Results: In both populations, the risk of death and bronchopulmonary dysplasia were higher for children with a birth weight <10th percentile of neonatal growth curves but also for children with a higher birth weight (between the 10th and the 24th percentile of neonatal growth curves or <10th percentile of fetal growth curves). In contrast, there was no link between neurological complications and low birth weight and no interactions with pregnancy complications. IUGR was associated with neurocognitive delay among extremely preterm children evaluated at two years of corrected age, especially for fine motor and social interaction skills, but not for language and gross motor skills. We did not find any association between IUGR and the risk of cerebral palsy at two years of corrected age. Conclusions: The use of the 10th percentile of neonatal growth curves is not suitable for identifying the impact of IUGR in very preterm infants; using higher thresholds or fetal growth curves is necessary. IUGR increased the risks of mortality and bronchopulmonary dysplasia, but was not associated with severe brain damage; these associations are observed in multiple clinical contexts (vascular and infectious pregnancy complications, and births at very early gestational ages). IUGR is a risk factor for poor medium-term neuro-development. Our results raise new questions about the appropriate surveillance for children with IUGR after discharge from the hospital and also about possible biological mechanisms that could explain the relationship between IUGR and respiratory morbidity and neurocognitive development

Full textAbstract:
Les premiers recyclages d’enrobés bitumineux à 50% sont apparus sur autoroutes françaises dans les années 1990 – une charte de l’innovation spécifique aux enrobés drainants intégrant 50% de recyclés fut notamment délivrée début 2002 (SETRA - CSTR, 2002). Un nouveau cycle de recyclage à fort taux de ces tout premiers enrobés a été entrepris ici ou là, depuis quelques années. Le multirecyclage des agrégats d’en-robé (AE) dans les mélanges d’enrobés bitumineux est de ce fait une problématique actuelle, qui va se gé-néraliser dans l’avenir, lorsqu’il faudra recycler des enrobés contenant déjà des enrobés recyclés plusieurs fois. Le projet visant à étudier le MUlti-Recyclage des Enrobés tièdes a été labellisé projet national (PN MURE). Une part du projet MURE regroupant des aspects scientifiques particuliers a été regroupé au sein du projet « IMPROVMURE », financé par l’Agence Nationale de la Recherche, et qui a débuté en mars 2014. L’objectif du projet « Innovation en Matériaux et PROcédés pour la Valorisation du MUlti-Recyclage des En-robés » (IMPROVMURE) est de fournir des éléments de réponse raisonnés et quantifiés, en laboratoire et sur sites pilotes, afin de faire du multi-recyclage des enrobés fabriqués à chaud et tiède. Les questions sociétales, environnementales, règlementaires ou normatives sont également prises en compte dans le cadre du projet. Un des objectifs du projet IMPROVMURE est l’étude des propriétés thermomécaniques des enrobés. C’est dans le cadre de cet objectif que s’inscrit le travail de thèse présenté dans ce document. Cette thèse est le fruit d’une collaboration entre le Laboratoire Génie Civil et Bâtiment de l’ENTPE (LGCB)/Laboratoire de Tribologie et Dynamique des Systèmes (LTDS) et l’entreprise EIFFAGE Infrastructures. 15 types d’enrobés ont été testés pour l’étude des propriétés thermomécaniques des enrobés multi-recyclés. Les enrobés diffèrent par leur condition de fabrication (Laboratoire ou chantier), leur procédé de fabrication (chaud ou tiède mousse), le taux d’agrégat d’enrobé introduit (0%, 40%, 70% ou100%) et le nombre de cycles de recyclage (un, deux ou trois). Trois caractéristiques ont été communes à tous les types d’enrobés fabriqués, sauf pour l’enrobé contenant 100% d’agrégats d’enrobé. La première est la même courbe granulométrique des granulats, la troisième est la teneur en liant de 5.4% en masse et la troisième est le type d’enrobé « Béton Bitumineux Semi-Grenu » (BBSG) de type 03 selon la norme EN 13108-1. Trois domaines du comportement des enrobés bitumineux ont été étudies : Viscoélasticité linéaire (VEL), couplage thermomécanique à basse température et fissuration à froid. Pour le domaine de comportement VEL, les enrobés bitumineux ont été étudiés à l’aide des essais de module complexe en traction-compression réalisés sur une large gamme de températures et de fréquences sur éprouvette cylindrique à l’ENTPE. Les résultats sont modélisés à l’aide du modèle analogique 2S2P1D qui a été développé au laboratoire LGCB de l’ENTPE. Des essais de propagation d’ondes ont aussi été réalisés. La méthode de détermination du temps de vol des ondes « P » et des ondes « S » et la méthode Impact Résonance sont utilisées. Ces essais utilisent des méthodes non destructives et faciles à réaliser. On peut ainsi calculer les valeurs de modules et de coefficients de Poisson des matériaux. Puis, le couplage thermomécanique à basse température est caractérisé à l’aide de l’essai de retrait thermique empêché (TSRST), qui utilise le même dispositif que l’essai de module complexe mais les éprouvettes utilisées sont de géométrie différente. Finalement des essais de propagation de fissure ont été réalisés avec des sollicitations monotones. La propagation de la fissure suivie utilisant la méthode de corrélation des images. Des estimations de la hauteur de fissure ont été faites sur la basse de la méthode DRCL développée à l’ENTPE<br>Reuse of Reclaimed Asphalt Pavement (RAP) is considered as one of the main solutions to cope with the objectives of worldwide sustainable development. In this way, the reuse of RAP in bituminous mixtures has been matter of study in previous papers (Chen et al., 2009; Kaur et al., 2013; Mogawer et al., 2012; Ru-bio et al., 2012; Sias Daniel et al., 2013; Valdés et al., 2011) and had concluded be economically profitable as well as had demonstrated the durability of the tested materials. Nowadays, new topics overcome dealing with how increase the RAP content and how many times RAP could be recycled. In France, a collaborative research and development project called “Multi-recycling of warm foam bitu-minous mixtures” (MURE) have brought together all the stakeholders involved in road construction. The pro-gram has run since March 2014. The scientific part of MURE project is IMPROVMURE project (Innovation for Materials and Processes for Improving the Multi-Recycling of Mixes). The overall budget of the project were €4.7M, €2.3M of which been provided by the ANR (National Re-search Agency) in the framework of the IMPROVMURE project, which has gotten under way in March 2014 and its main goal of characterizing the remobilization of the binder from recycled materials was the evalua-tion of the durability of mixes with the addition of binder. Thus, one objective of this project is to determine the thermomechanical properties of multi-recycled bi-tuminous mixtures, so in the context of this goal the current study was made. Likewise this investigation was a collaboration between the Tribology and System Dynamics Laboratory (LTDS) of the University of Lyon/ENTPE (“Ecole Nationale des Travaux Publics de l’Etat” ) and the French company EIFFAGE Infra-structures. For this study 15 types of bituminous mixtures were tested, the bituminous mixtures were produced in the laboratory and construction site, also two different techniques were studied for mixtures elaboration: hot and warm using foamed bitumen in both cases, the RAP content on these were 0%, 40%, 70% and even close to 100% produced after several recycling operations (up to 3 cycles). All bituminous mixtures have 3 invariants: the first is the same aggregate grading curves (except the bituminous mixture with 100% of RAP). The second one is the total binder content (5.4% in total weight). The last is classified as BBSG-03 0/10 bitu- 15 minous mixture, as is specified in the European standards for classification of bituminous mixtures (NF EN 13108-1 - 2007). Three domains of behaviour were studied: Linear Viscoelastic behaviour (LVE), cracking behaviour at low temperature and the fracture behaviour at low temperature. The LVE was studied considering complex modulus tests on bituminous mixtures and were performed in tension/compression on cylindrical samples, thus LVE behaviour was then modelled with 2S2P1D rheological model, developed at Uni. of Lyon / ENTPE, for the other hand cracking behaviour at low temperature was studied considering Thermal Stress Restrained Specimen Tests (TSRST), and finally fracture behaviour at low temperature was studied with the crack propagation tests as a monotonic loading

Full textAbstract:
Le transport des ondes joue un rôle majeur dans les systèmes de communication comme le Wifi ou les fibres optiques. Les principaux problèmes rencontrés dans ces systèmes concernent la protection contre les intrusions, la consommation d’énergie et le filtrage modal. Nous proposons différentes expériences micro-ondes mettant toutes en œuvre une mise en forme des ondes, pour traiter ces problèmes. Dans une cavité micro-ondes, des états de diffusion particuliers sont générés en s’appuyant uniquement sur des mesures de transmission et sur le formalisme du temps de retard de Wigner-Smith. Ces états sont capables d’éviter une région déterminée de la cavité, de se concentrer sur un point particulier, ou de suivre une trajectoire d’une particule classique. Le filtrage de mode est mis en œuvre dans un guide d’ondes aux frontières ondulées et en présence de pertes dépendant de la position. Le profil du guide est choisi de façon à ce que les deux modes de Bloch qui se propagent encerclent un point exceptionnel. Cette trajectoire s’accompagne d’une transition non-adiabatique entre les deux modes et d'un filtrage asymétrique de ces modes. La thèse présente également des travaux liés à la problématique des algorithmes de « recherche quantique », notamment l’algorithme de Grover. Cette recherche est mise en œuvre dans un réseau en nid d’abeilles de résonateurs micro-ondes couplés, bien décrits par un modèle de liaisons fortes (le système constitue un analogue micro-ondes du graphène). Une expérience de preuve de principe propose la recherche de deux résonateurs distincts reliés au réseau. La loi d’échelle attendue pour cet algorithme est expérimentalement obtenue dans une chaîne linéaire<br>Transport of waves plays an important role in modern communication systems like Wi-Fi or optical fibres. Typical problems in such systems concern security against possible intruders, energy consumption, time efficiency and the possibility of mode filtering. Microwave experiments are suited to study this kind of problems, because they offer a good control of the experimental parameters. Thus we can implement the method of wave shaping to investigate atypical transport phenomena, which address the mentioned problems. Wave front shaping solely based on the transmission together with the Wigner-Smith time delay formalism allows me to establish special scattering states in situ. These scattering states avoid a pre-selected region, focus on a specific spot or follow trajectories of classical particles, so called particle-like scattering states. Mode filtering is induced inside a waveguide with wavy boundaries and position dependent loss. The boundary profiles are chosen in such a way that the two propagating modes describe an encircling of an exceptional point in the Bloch picture. The asymmetric mode filtering is found due to the appearing non-adiabatic transitions. Another part of my work deals with Grover’s quantum search. I put such a search into practice in a two-dimensional graphene-lattice using coupled resonators, which form a tight-binding analogue. In this proof of principle experiment we search for different resonators attached to the graphene-lattice. Furthermore, the scaling behaviour of the quantum search is quantified for a linear chain of resonators
