Cette thèse s'inscrit à l'avant-garde de la logistique maritime et explore le potentiel transformateur de la technologie blockchain pour améliorer la traçabilité de la chaîne d'approvisionnement et faciliter l'échange de données sécurisé et multi-source. À travers une analyse approfondie des applications de la blockchain, ce travail de recherche examine méticuleusement comment cette technologie émergente peut contribuer de manière significative à renforcer la transparence, la traçabilité et la sécurité au sein du commerce international. En s'appuyant sur un cadre théorique complet et des études de cas concrets, cette étude universitaire met en lumière les défis et les opportunités à multiples facettes liés à l'intégration de la blockchain dans la logistique maritime. Elle évalue de manière critique l'impact de cette technologie sur la traçabilité des données critiques au sein des systèmes d'information maritimes, telles que les marchandises dangereuses et les journaux d'identification, avec le potentiel de s'étendre à un échange de données inter et intra plus large. Cette thèse vise non seulement à enrichir les connaissances universitaires, mais également à servir d'appel à l'action pour les innovateurs et les décideurs politiques des secteurs maritime et technologique. Elle préconise une approche innovante qui favorise un engagement plus profond avec les possibilités de transformation offertes par la blockchain. Cette approche considère la blockchain non pas comme un substitut, mais comme une couche complémentaire aux systèmes d'information maritime existants. Elle envisage une intégration et une utilisation transparentes d'une technologie blockchain personnalisée et évaluée au sein du secteur maritime, garantissant ainsi sa cohérence avec les exigences spécifiques de l'industrie et les tendances actuelles de numérisation. Ce travail de recherche vise à fournir des éclairages qui permettent de mieux comprendre les implications de la technologie blockchain pour le paysage en évolution du commerce et de la logistique mondiauxAt the forefront of maritime logistics, this dissertation explores the transformative potential of blockchain technology to enhance supply chain traceability and facilitate secure, multi-source data exchange.Through a deep analysis of blockchain applications, the research meticulously examines how this emerging technology can significantly elevate transparency, strengthen traceability, and fortify security within the global trade arena. By weaving together a comprehensive theoretical framework and real-world case studies, this scholarly endeavour sheds light on the multifaceted challenges and opportunities associated with integrating blockchain into maritime logistics. It critically evaluates the technology's impact on the traceability of critical data within maritime information systems, such as dangerous goods and identification logs, with the potential to extend to broader inter- and intra-data exchange. This dissertation not only contributes to academic knowledge but also serves as a compelling call to action for innovators and policymakers in the maritime and technology sectors. It advocates for an innovative approach that fosters deeper engagement with the possibilities of blockchain-driven transformation. This approach views blockchain not as a replacement, but as a complementary layer to existing maritime information systems. It envisions seamless integration and utilization of customized and evaluated blockchain technology within the maritime sector, ensuring its coherence with industry-specific requirements and ongoing digitization trends. This research aims to provide insights that enhance the understanding of blockchain technology's implications for the evolving global trade and logistics landscape

Cette thèse présente une méthodologie d’ordonnancement cyclique robuste appliquée à la gestion des conteneurs dans les ports maritimes de taille moyenne. Ces derniers sont sujet constamment à des variations des conditions des terminaux, la visibilité réduite sur des évènements futurs ne permet pas de proposer une planification précise des tâches à accomplir. L’ordonnancement cyclique robuste peut jouer un rôle primordial. Il permettra non seulement de proposer un ordonnancement prédictif pour le transport des conteneurs, mais aussi, il proposera également une planification robuste permettant d’éliminer les perturbations éventuelles en temps réel. Dans ce travail nous utilisons les Véhicules Intelligents Automatisés (AIV) pour transporter les conteneurs et nous modélisons les procédures de transit de ces derniers par des graphes d’évènements P-temporels fortement connexes (PTSCEG). Avant l’arrivée d’un porte conteneur au port, un plan (planning) de transport des conteneurs est proposé en un temps court par la programmation linéaire mixte (MIP). Des algorithmes polynomiaux de calcul de robustesse permettent de calculer sur les différents nœuds du système les marges de robustesse. Une fois le navire à quai, l’ordonnancement cyclique robuste est appliqué. Lorsqu’une perturbation est observée (localisée) dans le système, une comparaison avec la marge de robustesse connue est effectuée. Si cette perturbation est incluse dans la marge de robustesse, l’algorithme robuste est utilisé pour éliminer ces perturbations en quelques cycles. Dans le cas où la perturbation est trop importante, la méthode MIP est utilisée pour calculer un nouvel ordonnancement cyclique en un temps réduitThis PhD thesis is dedicated to propose a robust cyclic scheduling methodology applied to container management of medium sized seaport which faces ever changing terminal conditions and the limited predictability of future events and their timing. The robust cyclic scheduling can be seen not just a predictable scheduling to compute a container transportation schedule, but also a reactive scheduling to eliminate the disturbances in real time. In this work, the automated intelligent vehicles (AIV) are used to transport the containers, and the P-time strongly connected event graph (PTSCEG) is used as a graphical tool to model the container transit procedures. Before the arrival of the container vessel, a cyclic container transit schedule can be given by the mixed integer programming (MIP) method in short time. The robustness margins on the nodes of the system can be computed by robustness algorithms in polynomial computing time. After the stevedoring begins, this robust cyclic schedule is used. When a disturbance is observed in system, it should be compared with the known robustness margin. If the disturbance belongs to the robustness margin, the robustness algorithm is used to eliminate the disturbance in a few cycle times. If not, the MIP method is used to compute a new cyclic schedule in short time

The widespread use of social media, along with the possibilities to conceal one’s identity in the fibrillation of ubiquitous technology, combined with crime and terrorism becoming digitized, has increased the need of possibilities to find out who hides behind an anonymous alias. This report deals with authorship verification of posts written on Twitter, with the purpose of investigating whether it is possible to develop an auxiliary tool that can be used in crime investigation activities. The main research question in this report is whether a set of tweets written by an anonymous user can be matched to another set of tweets written by a known user, and, based on their linguistic styles, if it is possible to calculate a probability of whether the authors are the same. The report also examines the question of how linguistic styles can be extracted for use in an artificially intelligent classification, and how much data is needed to get adequate results. The subject matter is interesting as the work described in this report concerns a potential future scenario where digital crimes are difficult to investigate with traditional network-based tracking techniques. The approach to the problem is to evaluate traditional methods of feature extraction in natural language processing, and by classifying the features using a type of recurrent neural network called Long Short-Term Memory. While the best result in an experiment that was carried out achieved an accuracy of 93.32%, the overall results showed that the choice of representation, and amount of data used, is crucial. This thesis complements the existing knowledge as very short texts, in the form of social media posts, are in focus.

Le Port de Marseille-Fos, fort de ses 10 000 hectares à l’embouchure du 2ième plus grand fleuve du bassin méditerranéen, est un nœud d’un réseau global et un noyau d’un réseau local. A l’interface des enjeux maritimes et terrestres, l’aire d’influence de ce port international doit prendre conscience de ce système complexe qui l’entoure. C’est le principal objectif de ce travail de recherche action. L’approche présentée est structurée autour du concept d’“Usine Territoriale” qui relie la vision analytique de la productivité associée à l’usine et la vision systémique associée au développement territorial durable. Ce concept a permis de mettre en œuvre un processus, basé sur de la prospective volontariste, de la concertation, de l’action et de l’innovation, qui a fait réagir le réseau local du port, en le faisant passer d’un état passif à un état réceptif…première étape vers un pacte territorial. Le travail réalisé se fonde sur une analyse précise de la problématique du système portuaire et il propose une méthode qui permet d’“instrumentaliser ” l’“Usine Territoriale” pour mieux comprendre et piloter ses boucles de régulation / rétroaction (économique, environnementale et sociale). Des résultats concrets sont présentés et commentés pour enfin proposer un schéma directeur d’Intelligence Economique Territoriale de l’aire d’influence du Port de Marseille-Fos. Cette thèse n’est que la première étape d’un long chemin qui mènera ce territoire vers de nouvelles richessesThe Port of Marseille-Fos, strengthened by its 10 000 hectares located at the mouth of the second largest river of the mediterranean basin is a center piece of a global network and a central core of a local network. Interfacing maritime and land stakes, the area which is influenced by this international port must become aware of this complex system which surrounds it. It is the main object of this action research work. The approach presented is structured around the concept of the "territorial manufacturing plant" which links the analytical vision of productivity to that of the plant and the systemic vision associated to sustainable territorial development. This concept has enabled the setting up of a process based on volontary prospective, concertation, action and innovation, which aroused the port's local network, which allowed it to change from a passive state to a receptive one. . . First step toward a territorial pact. The work carried out is based on a precise analysis of the port system problematic and it proposes a method which allows to coordinate the territorial "manufacturing plant" in order to better understand and govern its regulation systems / retroactions (economic, environmental and social). The concrete results are presented and commented in order to finally propose a Territorial Economic Intelligence Master Plan for the areas influenced by the Port of Marseille-Fos. This thesis is the first step of a long process which will lead this territory toward new richnesses

Pełny tekst źródłaStreszczenie:
Numerous decisions in organisations are made by teams, groups or committees. The need for group decision making is brought about by the increased complexity of many decisions which require specialised knowledge in numerous areas usually not possessed by one person. As such there has also been an inherent recognition that different members bring different contributions and that a marshalling of these contributions enhances decision-making. Most research about how to make teams more effective has focused on identifying the task processes that distinguish the most successful teams - that is specifying the need for collaboration, involvement and commitment to goals. The assumption seems to be that, once identified; these processes can simply be imitated by other teams, with similar effects but it is not the case since they do not take the level of the team’s emotional intelligence into consideration. Emotional intelligence should always be considered in a team setting since teamwork is an inherently social activity and as such emotions play an important role in team processes including decision making. Surprisingly the study of the effects of emotions and emotional intelligence in decision making at group level is a relatively new research avenue. Research indicates that emotional intelligence has been the subject of a significant amount of literature for a number of years. However little has been contributed to how the behaviours associated with emotional intelligence may be practically applied to enhance both individual and group decision-making. Druskat and Wolff (2001a and 2001b) proposed a model for emotional intelligence at the group level. According to their model, groups develop a set of behavioural norms called the Group Emotional Competence Norms (GEC norms) which guide the emotional experience in groups. The proposed model by Druskat and Wolff was used to define and measure group emotional intelligence in this study. The aim of the study was to establish whether there was a relationship between team emotional intelligence and team decision making at Transnet Port Terminal’s Ngqura Container Terminal. The findings of the literature study and the empirical study were combined to evaluate whether team emotional intelligence affected team decision making in the chosen population.The literature study suggested that there was a relationship between team emotional intelligence and team decision making. The empirical study confirmed the relationship between group emotional intelligence and group decision making but failed to confirm whether the chosen population consisted of teams.

The overwhelming majority of global trade is executed over maritime infrastructure, and port-side optimization problems are significant given that commercial maritime ports are hubs at which sea trade routes and land/rail trade routes converge. Therefore, optimizing maritime operations brings the promise of improvements with global impact. Major performance bottlenecks in maritime trade process include the handling of insurance claims on shipping containers and vessel service time at port. The former has high input dimensionality and includes data pertaining to environmental and human attributes, as well as operational attributes such as the weight balance of a shipping container; and therefore lends itself to multiple classification method- ologies, many of which are explored in this work. In order to compare their performance, a first-of-its-kind dataset was developed with carefully curated attributes. The performance of these methodologies was improved by exploring metalearning techniques to improve the collective performance of a subset of these classifiers. The latter problem formulated as a schedule optimization, solved with a fuzzy system to control port-side resource deployment; whose parameters are optimized by a multi-objective evolutionary algorithm which outperforms current industry practice (as mined from real-world data). This methodology has been applied to multiple ports across the globe to demonstrate its generalizability, and improves upon current industry practice even with synthetically increased vessel traffic.

Pełny tekst źródłaStreszczenie:
Les troubles musculo-squelettiques (TMS) sont les première causes de maladies professionnelles en France.Les TMS affectent tous les domaines industriels et des services; de l'industrie lourde et manufacturière aux services d'aide à la personne en passant par les manutentions dans les centres logistiques.Ils peuvent notamment apparaitre suite à un port de charges, particulièrement critiques en raison des efforts intenses et répétés que cette tâche nécessite. Une solution pour prévenir l'apparition des TMS est d'assister physiquement les travailleurs afin de réduire l'effort engendré.Les exosquelettes apparaissent comme un des outils les plus prometteurs pour fournir cette assistance.Cependant, leur commande est un des verrous limitant leur mise en fonction dans l'industrie. C'est sur ce point que ce travail de recherche s'est focalisé. Ainsi une stratégie de contrôle d'un exosquelette de membres supérieurs pour l'assistance au port de charge sans connaissance à priori de la masse a été développée et intégrée.L'originalité de ce travail de recherche vient de l'estimation de l'intention en effort de l'utilisateur via son activité musculaire, estimée grâce à des capteurs électromyographiques, et de son utilisation dans la commande en effort d'un exosquelette. Ceci permet notamment de compenser le poids de charges non connues à priori.Ce système de détection d'intention est basé sur une méthode hybride intégrant un modèle du couple développé en fonction de l'activité musculaire et un réseau de neurones artificiels.Le système de contrôle a ensuite été évalué avec dix utilisateurs. Il a été constaté que cette méthode induisait : (i) des performances équivalentes à une assistance par compensation de gravité classique (avec connaissance à priori de la charge), mais aussi(ii) une réduction de l'activité musculaire du participant. L'impact de la personnalisation des paramètres (gain du contrôleur) sur les utilisateurs a également été analysé, et ce travail a démontré que cette personnalisation facilite la prise en main intuitive du système.Au cours des développements une attention particulière a été de proposer une approche facilement déployable sur le terrain, afin de tenir compte de l'orientation industrielle des applications.En effet, ce travail de recherche ouvre des perspectives d'applications pour les exosquelettes actifs dédiés au port de charges, comme par exemple dans le secteur de la logistique où les charges à manipuler sont variéesMusculoskeletal disorders (MSD) are the leading cause of occupational disease in France.MSDs affect all areas of industry and services; from heavy and manufacturing industry to personal assistance services and handling in logistics centers.MSDs may appear after carrying loads, this task being particularly critical because of the intense and repeated efforts that it requires. One solution to prevent the appearance of MSDs is to physically assist workers in order to reduce the effort involved.Exoskeletons appear to be one of the most promising tools for providing this assistance.However, their control is one of the locks slowing down their deployment in the industry.This doctoral project aims to investigate control and command of an exoskeleton in interaction with an operator. Thus, a strategy to control an upper-limb exoskeleton for load carrying assistance, without prior knowledge of the mass, was developed and integrated.The originality of this research work lies in two points. The first one is the estimation of the user's intention as a torque via his muscular activity, measured with electromyographic sensors. And the second one is the use of this estimated intention in the effort control of an exoskeleton. This approach makes possible to compensate the weight of loads that are not known beforehand.This intention detection system is based on a hybrid method integrating a model of the torque applied according to the muscular activity and an artificial neural network, in order to evaluate the direction of the movement intended.The control system was then evaluated through an experimental protocol with ten participants. It was found that this method induced : (i) performances equivalent to a classical gravity compensation assistance (with prior knowledge of the load), but also (ii) a reduction of the participant's muscular activity (biceps, anterior deltoid, and erector spinae).Finally, a method of personalization of the the control system based on the user's response time was designed.The impact of the personalization of the parameters (controller gain) on the users was also analyzed, and this work demonstrated that this personalization facilitates the intuitive handling of the system.During development, particular attention was given to proposing an approach that could be easily deployed in the workplace, in order to take into account the industrial orientation of the applications.Indeed, this research work opens up new application perspectives for active exoskeletons dedicated to load carrying, such as in professional logistic area

La conception est une des tâches intellectuelles des plus nobles et des plus complexes de l'homme. En particulier dans le monde industriel, la conception est devenue le propre de l'ingénieur, métier qu'il exerce avec très peu d'outils méthodologiques et informatiques pour les phases préliminaires du design. Les techniques d'intelligence artificielle, et tout particulièrement les systèmes à base de connaissances (SBC), offrent des moyens potentiels pour aider l'ingénieur dans son activité créatrice, et automatiser ses tâches routinières, et ainsi lui laisser obtenir la qualité souhaitée pour les études préliminaires. La réflexion menée lors de cette thèse, s'est focalisée sur les modèles théoriques du design, sur les mécanismes de représentation en IA pour la conception en ingénierie, et sur l'organisation du contrôle et de la communication pour la coopération de SBC. Une réflexion motivée par la réalisation d'un environnement intégré de conception automatisée, pour le domaine portuaire, EXPORT. Cette thèse aborde en effet la conception en ingénierie en tant qu'activité de résolution de problème. Elle propose l'utilisation de techniques des SBC pour la réalisation d'un tel environnement, intégrant des techniques et des outils divers (existants ou non). La question principale est alors d'organiser, au sein d'une architecture adaptée, de tels systèmes industriels (opérationnels) de Conception Intelligente Assistée par Ordinateur (CIAO). Il s'agit en particulier d'organiser les connaissances (de contrôle et de domaine), de les repartir pour obtenir des facteurs de qualité logicielle acceptables (maintenabilité, modularité, réutilisabilité, fiabilité, faisabilité, etc. ). Nous proposons une architecture de tableau, avec des connaissances distribuées, et un contrôle hiérarchique. Cette réponse est satisfaisante pour la classe de problèmes de conception routinière, ou interviennent des spécialistes (SBC) faiblement couplés entre eux.

This work had the main goal of analyzing the process of implementation of the Business Intelligence tool (BI) in a small company of the retail area of the construction of the West of Paraná (Brazil). As secondary objectives were raised the main limiters that restrict the implementation of the tool, it was evaluated the contribution of the Business Intelligence tool to the performance of the organization, and propose an implementation model for small companies. Therefore, we used the case study method with direct observation and interviews with the managers and collaborators who use the tool. The results obtained in the study demonstrated that there are several limitations to the implementation of Business Intelligence in small companies, among them, hardware and software limitation, process limitations and limitation of human resources. Such limitations can easily be overcome through the use of a model, which contemplates a flow of activities to be followed, demonstrating that the benefits generated by the tool for the performance of these organizations are notorious. Thus, the study was justified by the contribution that Business Intelligence brings to the performance of small companies, besides contributing directly to regional development through the role of employment creation, income and taxes of these enterprises.
Este trabalho teve como objetivo analisar o processo de implantação da ferramenta Inteligência de Negócio (IN) em uma empresa de pequeno porte da área de varejo da construção do Oeste do Paraná (Brasil). Como objetivos secundários foram levantados os principais limitadores que restringem essa implementação, foi avaliada a contribuição da ferramenta Inteligência de Negócio para o desempenho da organização, além de ser proposto um modelo de implementação para empresas de pequeno porte. Para tanto foi utilizado o método de estudo de caso com observação direta e entrevistas com os gestores e colaboradores que utilizam a ferramenta. Os resultados obtidos no estudo demonstram que existem diversas limitações para a implantação da Inteligência de Negócio em pequenas empresas, dentre eles, limitação de hardware e software, limitações de processo e limitação de recursos humanos. Tais limitações podem ser superadas facilmente a partir da utilização de um modelo que contemple um fluxo de atividades a ser seguido, demonstrando que são notórios os benefícios gerados pela ferramenta para o desempenho destas organizações. Desta forma, o estudo justificou-se pela contribuição que a Inteligência de Negócio traz para o desempenho das pequenas empresas, além de contribuir diretamente com o desenvolvimento regional pelo papel de geração de emprego, renda e tributos destes empreendimentos.

Haptic systems incorporate many different components, ranging from virtual simulations, physical robotic interfaces (super joysticks), robotic slaves, signal communication, and digital control; two-port networks offer compact and modular organization of such haptic components. By establishing specific stability properties of the individual component networks, their control parameters can be tuned independently of external components or interfacing environment. This allows the development of independent haptic two-port networks for interfacing with a class of haptic components. Furthermore, by using the two-port network with virtual coupling paradigm to analyze linear haptic systems, the complete duality between an admittance controlled device with velocity (position) feedback and virtual coupling can be compared to an impedance controlled device with force feedback and virtual coupling.
This research first provides background on linear haptic two-port networks and use of Llewelyn's Stability Criterion to prove their stability when interfaced with passive environments, with specific comments regarding application of these linear techniques to nonlinear systems. Furthermore, man-machine interaction dynamics are addressed, with specific attention given to the human is a passive element assumption and how to include estimated human impedance / admittance dynamic limits into the two--port design. Two--port numerical tuning algorithms and analysis techniques are presented and lay the groundwork for testing of said haptic networks on HuRBiRT (Human Robotic Bilateral Research Tool), a large scale nonlinear hybrid active / passive haptic display.
First, two-port networks are numerically tuned using a linearized dynamic model of HuRBiRT. Resulting admittance and impedance limits of the respective networks are compared to add insight on the advantages / disadvantages of the two different implementations of haptic causality for the same device, with specific consideration given to the advantage of adding force feedback to the impedance network, selection of virtual coupling form, effects of varying system parameters (such as physical or EMF damping, filters, etc.), and effects of adding human dynamic limits into the network formulation. Impedance and admittance two-port network implementations are experimentally validated on HuRBiRT, adding further practical insight into network formulation. Resulting experimental networks are directly compared to those numerically formulated through use of HuRBiRT's linearized dynamic models.

De nos jours, de plus en plus d’objets se connectent à Internet formant l’Internet des Objets (IoT). Les wearables, une classe de dispositifs constituant l’IoT, sont des équipements portés par un utilisateur qui permettent de détecter et traiter des signaux physiologiques. Le porteur de l’équipements peut ainsi recevoir directement des informations qualitatives sur son état de santé par exemple. Les données collectées pouvant par ailleurs être transmises sur le cloud pour une analyse plus approfondie. C’est dans ce contexte que la start-up Ellcie-Healthy développe des lunettes connectées intelligentes. L’objectif est d’améliorer la qualité de vie des utilisateurs et d‘éviter certains risques pour leur santé et leur sécurité (e.g. la détection des chutes). Pour cela, de nombreux capteurs ont été intégrés dans ces lunettes connectées afin de collecter et envoyer des données physiques, physiologiques et environnementales vers une passerelle, typiquement un smartphone. Or, concevoir des dispositifs wearables comporte de nombreux challenges tels que la consommation énergétique, la qualité de service (QoS) ou leur miniaturisation. Ces contraintes de conception, telles que l’autonomie ou la QoS, doivent être adressées tôt dans la phase de conception afin de garantir un respect des contraintes et des besoins utilisateurs. Dans cette thèse, nous proposons ainsi une méthodologie basée sur une approche de modélisation de haut niveau. L’objectif est d’aider les concepteurs, tôt dans le flot de conception, à effectuer les meilleurs choix des configurations matérielles et logicielles. Dans ce but, nous avons tout d’abord proposé des modèles analytiques de consommation de puissance pour les différents modules composant les lunettes connectées. Ces modèles, élaborés à partir de données mesurées directement sur des prototypes matériels, permettent pour différents scénarios applicatifs d’estimer la puissance consommée moyenne du système, et donc son autonomie. Les contraintes de performances (ou QoS) ont également été considérées dans notre approche de niveau système. L’application de détection de l’endormissement au volant, développée par Ellcie-Healthy, a été étudiée afin d’identifier les configurations matérielles et logicielles impactant le plus la consommation énergétique et la performance (i.e. la QoS liée à la détection des clignements des yeux). Une solution, basée sur un algorithme de réseaux de neurones convolutifs (CNN), a été proposée afin d’améliorer les performances de l’application. Bien que plus contraignantes en termes de temps d’exécution et d’empreinte mémoire, nous avons montré qu’il est possible d’exécuter ce type d’algorithme CNN at the edge (i.e. sur un microcontrôleur). Durant cette thèse, un banc de test a également été développé afin d’évaluer les conditions de sécurité et le phénomène de vieillissement des batteries. L’utilisation de cette plateforme expérimentale a permis de collecter de nombreuses informations liées au processus de charge/décharge de diverses batteries utilisées par l’entreprise. Différents modèles de batterie data-driven ont ainsi été proposés et validés pour différents cas d’usage. L’ensemble de ces modèles ont été intégrés dans un environnement de simulation, permettant ainsi de modéliser et simuler les versions actuelles ou futures des lunettes connectées intelligentes. Les concepteurs peuvent alors rapidement évaluer l’impact de différentes configurations matérielles et logicielles ou de politiques de gestion de l’énergie sur l’autonomie et les performances du système. Cette méthodologie générique de modélisation et simulation permet également de considérer d’autres types de dispositifs wearablesA growing number of physical objects are being connected to the Internet at an unprecedented rate realizing the idea of the Internet of Things (IoT). Wearables are a class of IoT devices worn on the body that can detect and process physiological signals. A wearable can then give bio-feedback to the wearer or send information to the cloud for further analysis. In this context, the Ellcie-Healthy start-up is developing an intelligent and connected eyewear solution with the aim at improving the user’s quality of life and to prevent risks for their health and safety. To do so, several sensors are integrated into the wearable eyeglass to collect and send physical, physiological and environmental information towards a gateway, typically a smartphone. Designing wearable devices deals with numerous challenges such as the energy consumption, the quality of service (QoS) and the scalability, to cite only a few. Several design constraints, such as the autonomy and QoS, must be addressed early in the design flow to ensure the wearable device will meet the user requirements. In this PhD thesis, we propose a simulation flow based on a system-level modeling approach to help designers making the best choices of hardware/software settings early in the design phase. To do so, we have first developed analytical power models for the Ellcie Healthy smart glasses. These models, built from data measured on the real platform, allow estimating the average power consumption of the system, and so the battery lifetime, for different application scenarios. Then, performance constraints have also been considered in our system-level approach. The drowsiness detection application, developed at Ellcie Healthy, has been profiled to identify the hardware and software configurations impacting the most the energy consumption and the application QoS, i.e. the detection performance. A solution based on a Convolutional Neural Network (CNN) has been proposed to further improve the drowsiness detection QoS. We have also demonstrated that it is possible to execute this CNN at the edge (i.e. on a micro-controller). A battery testbench has also been developed to evaluate battery safety conditions as well as the aging phenomenon. Using this experimental platform, a significant amount of information on the battery charge/discharge process has been collected. A data-driven battery model has been proposed and validated. All these models have been integrated into a simulation framework which allows modeling and simulating existing or future versions of the smart connected glasses. Using this framework, designers can rapidly investigate trade-offs between hardware and/or software settings, as well as study system autonomy and application QoS. In addition, this simulation flow can be used to evaluate power management strategies from a high-level point of view

Depuis la prolifération des bases de données partiellement étiquetées, l'apprentissage automatique a connu un développement important dans le mode semi-supervisé. Cette tendance est due à la difficulté de l'étiquetage des données d'une part et au coût induit de cet étiquetage quand il est possible, d'autre part.L'apprentissage semi-supervisé consiste en général à modéliser une fonction statistique à partir de base de données regroupant à la fois des exemples étiquetés et d'autres non-étiquetés. Pour aborder une telle problématique, deux familles d'approches existent : celles basées sur la propagation de la supervision en vue de la classification supervisée et celles basées sur les contraintes en vue du clustering (non-supervisé). Nous nous intéressons ici à la deuxième famille avec une difficulté particulière. Il s'agit d'apprendre à partir de données avec une partie étiquetée relativement très réduite par rapport à la partie non-étiquetée.Dans cette thèse, nous nous intéressons à l'optimisation des bases de données statistiques en vue de l'amélioration des modèles d'apprentissage. Cette optimisation peut être horizontale et/ou verticale. La première définit la sélection d'instances et la deuxième définit la tâche de la sélection de variables.Les deux taches sont habituellement étudiées de manière indépendante avec une série de travaux considérable dans la littérature. Nous proposons ici de les étudier dans un cadre simultané, ce qui définit la thématique de la co-sélection. Pour ce faire, nous proposons deux cadres unifiés considérant à la fois la partie étiquetée des données et leur partie non-étiquetée. Le premier cadre est basé sur un clustering pondéré sous contraintes et le deuxième sur la préservation de similarités entre les données. Les deux approches consistent à qualifier les instances et les variables pour en sélectionner les plus pertinentes de manière simultanée.Enfin, nous présentons une série d'études empiriques sur des données publiques connues de la littérature pour valider les approches proposées et les comparer avec d'autres approches connues dans la littérature. De plus, une validation expérimentale est fournie sur un problème réel, concernant le diagnostic de transport ferroviaire de l'état de la ThaïlandeWe are drowning in massive data but starved for knowledge retrieval. It is well known through the dimensionality tradeoff that more data increase informative but pay a price in computational complexity, which has to be made up in some way. When the labeled sample size is too little to bring sufficient information about the target concept, supervised learning fail with this serious challenge. Unsupervised learning can be an alternative in this problem. However, as these algorithms ignore label information, important hints from labeled data are left out and this will generally downgrades the performance of unsupervised learning algorithms. Using both labeled and unlabeled data is expected to better procedure in semi-supervised learning, which is more adapted for large domain applications when labels are hardly and costly to obtain. In addition, when data are large, feature selection and instance selection are two important dual operations for removing irrelevant information. Both of tasks with semisupervised learning are different challenges for machine learning and data mining communities for data dimensionality reduction and knowledge retrieval. In this thesis, we focus on co-selection of instances and features in the context of semi-supervised learning. In this context, co-selection becomes a more challenging problem as the data contains labeled and unlabeled examples sampled from the same population. To do such semi-supervised coselection, we propose two unified frameworks, which efficiently integrate labeled and unlabeled parts into the co-selection process. The first framework is based on weighting constrained clustering and the second one is based on similarity preserving selection. Both approaches evaluate the usefulness of features and instances in order to select the most relevant ones, simultaneously. Finally, we present a variety of empirical studies over high-dimensional data sets, which are well-known in the literature. The results are promising and prove the efficiency and effectiveness of the proposed approaches. In addition, the developed methods are validated on a real world application, over data provided by the State Railway of Thailand (SRT). The purpose is to propose the application models from our methodological contributions to diagnose the performance of rail dry port systems. First, we present the results of some ensemble methods applied on a first data set, which is fully labeled. Second, we show how can our co-selection approaches improve the performance of learning algorithms over partially labeled data provided by SRT

Les terminaux à conteneurs constituent des interfaces inter-modales essentielles pour le réseau de transport mondial. Une manutention efficace des conteneurs dans des terminaux est d'une importance cruciale pour la réduction des coûts de transport et la détermination des plans d'embarquement. Dans ce rapport de thèse, nous proposons principalement une approche de résolution distribuée à travers la description d'un modèle d'optimisation heuristique distribuée baptisé COSAH COntainer Stacking via multi-Agent approach and Heuristic methodqui permet de simuler, résoudre et optimiser l'espace de stockage disponible pour manier les départs et les arrivées des conteneurs dans un port fluvial ou maritime. Autrement dit, COSAH permet de minimiser le nombre total de mouvements parasites tout en respectant des contraintes dynamiques d'espace et de temps. Les performances de COSAH sont ensuite évaluées sur des instances générées aléatoirement, ainsi que des instances extraites de la réalité d'un port maritime tunisien : le port de Radès. En effet, nous avons procédé à une étude expérimentale implémentant et comparant COSAH à la version centralisée associée, toutes deux basées sur un algorithme de recherche non informée et un algorithme de recherche informée. Les résultats obtenus, présentés et illustrés, montrent l'efficacité de COSAH en particulier, et d'une méthode d'optimisation heuristique distribuée alliant les deux concepts : Agent et Heuristique, en général.

Le travail présenté dans ce mémoire contribue au domaine de l’entreprise étendue et le développement des systèmes d’informations distribués. et le développement des systèmes d’informations distribués. C’est bien évidemment un sujet d’étude important pour la communauté Logistique (chaîne logistique), mais aussi pour la communauté Génie logiciel. C’est dans cette perspective que se situent les objectifs de proposer une modélisation de la chaîne logistique globale dans un environnement de transport intermodal de porte à porte en vue de résoudre les problèmes : (i) d’interfaces entre les différents acteurs intervenants le long de la chaîne et (ii) de rupture des charges engendrés par les opérations de transfert de marchandises d’un mode de transport à l’autre. Ainsi, l’amélioration de performance de la chaine logistique dépend fortement du niveau de coopération et de coordination, et surtout du partage et de la validité des informations et des connaissances, entre ces différents acteurs de la chaîne (organisateur du transport, transitaire, fournisseur, etc.). L’applicatif se situe dans le corridor de la vallée de Seine. Le travail s’inscrit dans le projet APLOG (Amélioration et Performance de la LOgistique Globale) financé par la région Haute NormandieThe work presented in this thesis contributes to the field of the extended enterprise and the development of distributed information systems. This is obviously an important subject of study for the logistics community (supply chain), but also for the software engineering community. It is in this context that the objectives are to provide a model of global supply chain in an intermodal environment door to door service to solve the problems: (i) interfaces between the different actors involved along the chain and (ii) trans-loading operations generated by the goods transfer operations from one mode of transport to another. Thus, improved performance of the supply chain depends heavily on the level of cooperation and coordination, and especially sharing and validity of information and knowledge between the different actors in the chain (transport organizer, forwarding, Supplier, etc.). The application is located in the corridor of the Seine valley. The work is part of the project APLOG (Performance Improvement and global logistics) financed by the Haute Normandie region

SIMTUR - Sistema Inteligente De Monitoramento de Tráfego Urbano
O crescente aumento do uso de automóveis e de motocicletas tem provocado uma contínua degradação no trânsito urbano das grandes metrópoles. Este cenário é agravado pelas deficiências nos atuais sistemas de transporte público, geradas, em parte, pela falta de informação ao usuário. O presente trabalho apresenta um modelo computacional para um sistema de informação ao usuário de transporte público. Ao contrário de outros trabalhos baseados no algoritmo clássico Dijkstra, a abordagem apresentada faz uso do algoritmo A* para resolução do problema de caminhos mínimos, presente neste contexto, a fim de reduzir o tempo de resposta de maneira que o modelo possa ser utilizado em um sistema real de informação ao usuário. O modelo proposto considera múltiplos critérios de decisão, como a distância total percorrida e o número de transbordos. Um estudo de caso foi realizado utilizando dados reais do transporte público da cidade Porto Alegre com o objetivo de avaliar o modelo computacional desenvolvido. Os resultados gerados foram comparados com aqueles obtidos através do emprego do algoritmo Dijkstra e indicam que a combinação do algoritmo A* com técnicas de aceleração permite reduzir, significativamente, a complexidade de espaço, o tempo de processamento e o número de transbordos.
The increasing use of automobiles and motorcycles has caused a continuous degradation in the traffic of large cities. This scenario gets worse due to shortcomings in the current public transportation, which is entailed, in a certain way, by the lack of information provided to the user. This study shows a computing model for a public transportation user information system. Unlike other studies based on the classical Dijkstra’s algorithm, the approach makes use of the algorithm A* to solve a shortest path problem to reduce the response time so that the model can be used in an real-time web information system. The proposed model takes into account multiple criteria of decision, such as total distance traveled and number of transfers and it was evaluated with data from Porto Alegre’s public transportation. The results were compared to those ones obtained by the use of Dijkstra’s algorithm and indicate that the combination of algorithm A* with acceleration techniques allows reducing significantly the space complexity, processing time and the number of transfers.

Un système logistique est une composante essentielle d'un système spatial dans lequel les acteurs s'organisent autour d'infrastructures pour faire circuler des flux (de marchandises, d'information et financier) sur un territoire. L'organisation logistique globale résulte d'un processus auto-organisé et distribué de la part des acteurs. Ce travail vise à comprendre, à de multiples échelles, comment des acteurs autonomes et très hétérogènes (dans leurs modes de fonctionnements et dans leurs objectifs), s'organisent collectivement autour des infrastructures à leurs dispositions pour gérer des flux soumis à un ensemble de contraintes (temporelles, spatiales,...). On propose ici un modèle orienté agent permettant de simuler les processus de création et d'organisation des flux liés à la logistique sur un territoire. Le modèle prévoit de décrire l'interface entre les flux internationaux et les flux urbains afin de comprendre comment les dynamiques portuaires et urbaines cohabitent au sein du système. Le modèle intègre une dynamique structurelle et organisationnelle grâce aux graphes dynamiques afin de représenter l'évolution du système. Le modèle permet ainsi aux agents de s'adapter, comme dans la réalité, à des perturbations du systèmeA logistic system is an essential component of a spatial system. Actors are organised around infrastructures in order to move different kinds of flow (of goods, of information, or financial) over a territory. The logistic organisation comes from an auto-organised and distributed process from the actors. This works aims to understand, at different scales, how autonomous and heterogeneous actors (according to their goals and methods to take decisions) are collectively organised around infrastructures to manage different kinds of flow, and despite numerous constraints (temporal, spatial,...). We propose an agent-based model which allows to simulate the processes to create and organise logistic flow over a territory. The model describes an interface between international and urban flow in order to understand how the port and urban dynamics work together. The model integrates a structural and organisational dynamics thanks to dynamic graphs in order to represent the evolution of this kind of system. Thus, the agents can adapt themselves to system's perturbations as in the reality

Inteligência Competitiva (IC) é um tópico emergente e estratégico para nações e organizações, e na medida em que desenvolve-se no plano teórico, surge a necessidade de estabelecer interfaces com outras áreas do conhecimento. Neste caso, observou-se uma lacuna de estudos empíricos que buscassem relacionar a IC com o Envolvimento da Alta Direção, fator essencial para o desenvolvimento de atividades deste nível dentro de uma organização. Mais que o suporte inicial de recursos e legitimidade, o Envolvimento da Alta Direção pressupõe o comprometimento e a participação continua da Alta Direção da empresa em programas desta ordem, postura que pode ser de significativa diferença para o seu sucesso ou fracasso. Portanto, esta pesquisa objetivou analisar a relação entre o Envolvimento da Alta direção e as dimensões de Contexto e de Processo de Inteligência Competitiva em empresas de médio e de grande porte da Serra Gaúcha. Também se propôs a desenhar um panorama do nível de desenvolvimento de IC na região, limitado às organizações destes portes, e a explorar a existência de relações entre Envolvimento da Alta Direção, Inteligência Competitiva e Desempenho destas organizações. Neste sentido, foi desenvolvida uma pesquisa de caráter quantitativo descritivo, com base em survey aplicada em amostra de 168 organizações representativas do recorte deste estudo, utilizando-se escalas já operacionalizadas em estudos de IC internacionais, as quais têm como base o modelo composto das dimensões de processo e de contexto em IC. Os resultados indicaram que há relação positiva entre Envolvimento da Alta Direção e o nível de desenvolvimento em inteligência competitiva nas empresas de médio e de grande porte da Serra Gaúcha sendo identificadas as organizações numa matriz proposta nestas dimensões , e também foi observada uma associação positiva entre IC, Desempenho, Envolvimento da Alta Direção e a Integração das atividades de IC com o processo decisório destas empresas. Em termos de panorama do setor, observou-se que a maioria destas empresas desenvolve algum tipo de monitoramento (coleta de informação) de temas ainda que não denomine esta atividade de inteligência , sendo os focos principais em Vendas, Concorrentes e Produtos, indicando um caráter mais concorrencial, o que sinalizaria um princípio de desenvolvimento desta área nestas empresas da região.Submitted by Marcelo Teixeira (mvteixeira@ucs.br) on 2014-06-02T18:37:17Z No. of bitstreams: 1 Dissertacao Mateus Panizzon.pdf: 3058509 bytes, checksum: c437465a0948516e0e660ba039bab7cd (MD5)

Competitive Intelligence (CI) is an emergent topic with strategic importance for nations and enterprises, and with your continuum theoretical development, arise the necessity to establish links with another knowledge fields. It has been identified a gap of empirical studies that seek to relate CI with Top Management Involvement, an essential factor for the development of this activity within the organization. More than initial support of resources and legitimacy, Top Management Involvement presupposes the commitment and continuous participation of the Top Management in programs of this nature, a behavior that can be of significant influence for its success or failure. So, this research aimed to analyze the relationship between Top Management Involvement and the Context and Process dimensions of Competitive Intelligence Model in medium and large companies of Serra Gaúcha Brazil. Also, it has been proposed to learn about the level of CI development level in the region, limited to organizations of this size, and to explore the relations between Top Management Involvement, Competitive Intelligence and Performance at this organizations. Thus, a descriptive and quantitative research was carried out, based on a survey sample of 160 organizations, measured by scales proposed by another international studies and based on the theoretical model of context and process of IC. Results indicated that there is positive relationship between Top Management Involvement and the IC Development Level at the medium and large companies at Serra Gaúcha, and three out of four scenarios proposed can be perceived. Also there is a positive association between IC, Organizational Performance, Top Management Involvement and IC integration with the decision making process of these organizations. In general, it was observed that most of these companies developed some kind of monitoring (information collecting), even though they do not nominate this activity as "Intelligence". The main focus of monitoring are Sales, Competitors and Innovation in Products, which indicates a beginning of this field development in the companies of this region.d

La tendance actuelle est d'utiliser les systèmes multi-antennes en émission et en réception afin d'utiliser au mieux le spectre radioélectrique et d'améliorer la liaison radio pour les systèmes de communications sans fil. C'est dans ce contexte que s'inscrit ce mémoire de thèse qui porte sur l'étude et l'optimisation d'un démonstrateur d'antennes intelligentes. Après avoir effectué une étude approfondie des méthodes de détection de directions d'arrivée des signaux RF et développé une technique de formation de lobe, deux prototypes de système d'antenne adaptative ont été développés dans la bande WiMax (3. 4 - 3. 5 GHz) et validé expérimentalement. Le premier prototype fonctionnant en réception est basé sur les liaisons de type Uplink. Il utilise les démodulateurs cinq-ports et le système de formation numérique de faisceau où les poids sont calculés par l'algorithme SQP (technique de synthèse développée) et appliqués directement aux signaux en bande de base afin d'améliorer la qualité des signaux reçus c'est-à-dire améliorer le rapport signal à interférent plus bruit. Le deuxième fonctionnant en émission est basé sur les liaisons de type Downlink, c'est un système analogique de formation de faisceau utilisant les modulateurs vectoriels commandés numériquement à partir de la loi d'alimentation donnée par la synthèse de diagramme (algorithme SQP) afin de concentrer le rayonnement émis dans la direction privilégiée du récepteur utile. Ces deux systèmes sont complémentaires dans la mesure où ce dernier utilise les résultats de mesure de DoA du premier pour adapter son diagramme de rayonnement en fonction de la position angulaires des sourcesThe current tendency is to use the multi-antennas systems in emission and/or reception in order to optimize the radioelectric spectrum as well as possible and to improve the radio connexion for the wireless communication systems. It is in this context that this thesis is related to the study and optimization of a demonstrator of smart antennas. After having carried out a thorough study of the detection methods of directions of arrival of the RF signals and having developed a beamforming technique, two prototypes of adaptive antenna system were developed in the WiMax band (3. 4 - 3. 5 GHz) and experimentally validated. The first system functioning in reception is based on the Uplink. It uses the five-port demodulators and the numerical beamforming system where the weights are calculated by the SQP algorithm (technique of pattern synthesis developed) and directly applied to the signals in baseband in order to improve quality of the received signals i. E. To improve the signal to interference plus noice ratio. The second system functioning in emission is based on the Downlink ; it is an analogical beamforming system using the vectors modulators controlled numerically, starting form the weight given by the array pattern synthesis (SQP algorithm) in order to concentrate the radiation emitted in the desired direction of the useful receiver. These two systems are complementary insofar as the last one uses the results of measurement of DoA of the first one to adapt its radiation pattern according to the position angular of the sources

São crescentes os estudos voltados para o desenvolvimento de estratégias de integração e orientação à cadeia de suprimentos. Porém, a especificidade de cada cadeia exige que estudos sejam delineados conforme as características de cada indústria. Este trabalho pretende apresentar um modelo que auxilie na gestão de relacionamentos estratégicos de um terminal de containers, com base em conceitos relacionados a orientação à cadeia de suprimentos. O modelo é originado a partir da extensão do modelo de integração proposto por Lambert et al. (1998) e do modelo de mensuração da integração dos terminais portuários, desenvolvido por Song e Panayides (2007) e Panayides e Song (2008). Nesta proposta, são delimitados 3 diferentes níveis de relacionamento estratégico: monitoramento, mediação e criação de soluções, desenvolvidos a partir da inteligência de mercado que baliza os relacionamentos chave dimensionados pela estratégia do terminal portuário. O presente estudo propõe a aplicação do modelo desenvolvido no Tecon Rio Grande, terminal de containers do Porto de Rio Grande, a partir de duas etapas de pesquisa. A primeira etapa é uma pesquisa quantitativa e serviu para dimensionar a aderência entre a estratégia de orientação à cadeia da organização com relação aos seus relacionamentos chave, identificando possíveis discrepâncias. Nesta primeira etapa é apresentado o mapa de orientação ao relacionamento estratégico, ferramenta fundamental para análise. A segunda etapa trata-se de uma pesquisa qualitativa realizada para identificar os motivos das distorções apontadas pelos usuários chave da cadeia. Os resultados empíricos encontrados nas duas etapas da pesquisa demonstram que o modelo estendido apresentado alcança seu objetivo de identificar a OCS percebida e as variações aos diferentes níveis de relacionamento estrtégico, resultando como ferramenta para gestão de relacionamentos chave de terminais portuários.
There are increasing studies focused on the development of integration strategies and guidance to the supply chain. However, the specificity of each chain requires studies delineated according to the characteristics of each industry. This work intends to present a model that assists in managing strategic relationships of a container terminal, based on concepts related to supply chain orientation. The model is derived from the extent of the integration model proposed by Lambert et al. (1998) and the measurement model of the integration of port terminals, developed by Song and Panayides (2007) and Panayides and Song (2008). At this model are defined three different levels of strategic relationships: monitoring, mediation and creating solutions developed from market intelligence and targeted to key relationships scaled by the strategy of the port terminal. This study proposes to apply the model developed in Tecon Rio Grande, container terminal at the Port of Rio Grande, from two stages of research. The first step is a quantitative research and served to scale the adhesion between the chain orientation strategies of the organization with respect to their key relationships, identifying possible discrepancies. In this first step is also presented the map of the strategic relationship orientation, a fundamental tool for analysis. The second stage it is a qualitative research conducted to identify the reasons for the distortions noted by the chain members. Empirical results demonstrate that the extended model presented can be used as a tool for management of key relationships.

Cette thèse se penche sur deux défis de l'apprentissage fédéré: l'hétérogénéité des données et la sécurité des modèles. Dans la première partie, nous nous attaquons à l'hétérogénéité des données, une problématique inhérente aux applications d'apprentissage fédéré dans un cadre réaliste. Les clients peuvent avoir des distributions de données différentes à cause de leurs opinions, localisations ou habitudes. Nous nous concentrons sur deux types distincts d'hétérogénéité dans les tâches de classification. Premièrement, quand les participants ont des distributions de données différentes mais similaires, l'apprentissage collaboratif est une approche attrayante. Notre première méthode s'appuie sur une approche d'adaptation de domaine collaborative, pour apprendre un dictionnaire empirique. Ce dictionnaire exprime les données de chaque client sous la forme d'une combinaison linéaire d'atomes, qui sont des ensembles empiriques représentant les données d'entraînement. Les clients apprennent les atomes en collaboration, tandis que les poids de la combinaison linéaire sont appris individuellement pour assurer la confidentialité. Ce dictionnaire est ensuite utilisé pour déduire les classes d'un client avec une distribution non étiquetée, mais qui a activement participé au processus d'apprentissage. Notre deuxième méthode traite une forme différente d'hétérogénéité, où les clients expriment des concepts différents dans leurs distributions. Dans ce cas, l'apprentissage collaboratif n'est pas toujours optimal, mais nous supposons qu'il existe une similarité structurelle entre les clients, qui nous permet de les regrouper pour un apprentissage plus efficace. Nous nous intéressons particulièrement à la "scalabilité" de cette méthode, en supposant un nombre élevé de participants. Notre approche est conçue pour estimer la structure cachée entre les clients à chaque agrégation des mises à jour des clients, de manière incrémentale. Contrairement à d'autres approches, nous n'imposons pas que tous les clients soient disponibles simultanément pour estimer leurs clusters d'appartenance. Dans la partie suivante de cette thèse, nous examinons les défis de sécurité de l'apprentissage fédéré, spécifiquement sur la vulnérabilité aux attaques par porte dérobée pendant l'apprentissage. Un système fédéré étant partagé, il est difficile d'assurer que tous les clients sont honnêtes et envoient des mises à jour correctes. L'apprentissage fédéré est vulnérable aux utilisateurs malveillants qui corrompent leurs données. Nos défenses sont conçues pour les attaques par porte dérobée, activées par des déclencheurs. Elles reposent sur la reconstruction de ces déclencheurs, sans fournir au serveur des données ou informations supplémentaires provenant des clients, à l'exception des poids compromis. En supposant certaines hypothèses limitées, le serveur peut estimer le déclencheur de l'attaque à partir du modèle global compromis. Notre troisième méthode utilise le déclencheur estimé pour identifier les neurones d'un réseau encodant l'attaque. Nous proposons d'élaguer ce réseau pour entraver les effets de l'attaque. Cette approche défend efficacement un modèle corrompu, même en présence de données hétérogènes. Enfin, notre dernière méthode déplace la défense vers les utilisateurs, en leur fournissant le déclencheur reconstruit pour contrer les attaques pendant la phase d'inférence. Cette défense se révèle particulièrement efficace même dans les cas extrêmes d'hétérogénéité. En conclusion, cette thèse introduit des méthodes novatrices pour améliorer l'efficacité et la sécurité des systèmes d'apprentissage fédérés. Nous avons exploré divers scénarios d'hétérogénéité des données, en proposant des approches d'apprentissage collaboratif et des défenses. Nous perspectives de recherche envisagent d'améliorer notre reconstruction des déclencheurs et en prenant en compte d'autres défis, tels que la confidentialité, qui est une aspect important en apprentissage fédéréThis thesis addresses two significant challenges in federated learning: data heterogeneity and security. In the first part of our work, we tackle the data heterogeneity challenge. Clients can have different data distributions due to their personal opinions, locations, habits, etc. It is a common and almost inherent obstacle in real-world federated learning applications. We focus on two distinct types of heterogeneity in classification tasks. On the one hand, in the first scenario, participants exhibit diverse yet related data distributions, making collaborative learning an attractive approach. Our first proposed method leverages a domain adaptation approach and collaboratively learns an empirical dictionary. A dictionary expresses each client's data as a linear combination of various atoms, that are a set of empirical samples representing the training data. Clients learn the atoms collaboratively, whereas they learn the weights privately to enhance privacy. Subsequently, the dictionary is utilized to infer classes for the clients' unlabeled distribution that withal actively participated in the learning process. On the other hand, our second method addresses a different form of data heterogeneity, where clients express different concepts through their distributions. Collaborative learning may not be optimal in this context; however, we assume a structural similarity between clients, enabling us to cluster them into groups for more effective group-based learning. In this case, we direct our attention to the scalability of our method by supposing that the number of participants can be very large. We propose to incrementally, each time the server aggregates the clients' updates, estimate the hidden structure between clients. Contrary to alternative approaches, we do not require that all be available at the same time to estimate their belonging clusters. In the second part of this thesis, we delve into the security challenges of federated learning, specifically focusing on defenses against training time backdoor attacks. Since a federated framework is shared, it is not always possible to ensure that all clients are honest and that they all send correctly trained updates.Federated learning is vulnerable to the presence of malicious users who corrupt their training data. Our defenses are elaborated for trigger-based backdoor attacks, and rooted in trigger reconstruction. We do not provide the server additional data or client information, other than the compromised weights. After some limited assumptions are made, the server extracts information about the attack trigger from the compromised model global model. Our third method uses a reconstructed trigger to identify the neurons of a neural network that encode the attack. We propose to prune the network on the server side to hinder the effects of the attack. Our final method shifts the defense mechanism to the end-users, providing them with the reconstructed trigger to counteract attacks during the inference phase. Notably, both defense methods consider data heterogeneity, with the latter proving to be more efficient in extreme data heterogeneity cases. In conclusion, this thesis introduces novel methods to enhance the efficiency and security of federated learning systems. We have explored diverse data heterogeneity scenarios, proposing collaborative learning approaches and robust security defenses based on trigger reconstruction. As part of our future work, we outline perspectives for further research, improving our proposed trigger reconstruction and taking into account other challenges, such as privacy which is very important in the field of federated learning

Recently, an e-learning platform has been applied for scholars in the teaching, and it can effectively assist and obviously enhance students’ learning performance for most of students. Therefore, the role of teachers in the classroom has been gradually transformed into the counseling on the sidelines, and makes students learn self-directed learning and self-management, developing the ability of judgment and independent thinking and beyond conventional learning thinking. However, students’ knowledge background can only be judged by humane, not by the assistant of the system. Therefore, it will be an important issue for teachers to carry out meaningful teaching lessons based on each student’s knowledge background. It could increase the burden on teachers if we rely much on teachers to assess the improvement of students in knowledge background. In this thesis, an intelligent essay assessment system was proposed to analysis the content on the online discussion posts. At first, the keywords were extracted via the association rules, and then combined the sets selected by the experts or teachers. Next, we integrated the concepts of term frequency and TF-IDF, and did the classification with one-class SVM. Finally, we can determine if the students’ posts were correct or not, and this system can thus ease the burden on teachers. The experimental results indicated that the proposed essay assessment system can improve the recall rate, the accuracy rate, and the precision rate in terms of the performance of document classification before and after the combination of the keywords, and therefore, the burden on teachers can be alleviated with the proposed system.

This research examines the impact of underdog brand on consumers’ brand preference, as well as the moderating roles of emotional intelligence and sponsored posts in the impact of underdog brand on consumers’ brand preference. The research model is based upon the constructs and inferred hypotheses, and a 2 (with underdog brand story vs. without underdog brand story) × 2 (with sponsored posts vs, without sponsored posts) between-subjects factorial experimental design is conducted. Results demonstrate that underdog brand story has a positive impact on consumers’ brand preference. Moreover, the extent of emotional intelligence has no impact on consumers’ brand preference. Similarly, the availability of sponsored posts has no impact on consumers’ brand preference. Additionally, underdog brand story has a positive impact on consumers’ brand preference, regardless of the extent of consumers’ emotional intelligence. Similarly, underdog brand story has a positive impact on consumers’ brand preference, regardless of the availability of sponsored posts. Subsequently, consumers’ emotional intelligence has no impact on brand preference, regardless of the availability of sponsored posts. At last, underdog brand story has a positive impact on consumers’ brand preference, regardless of the availability of sponsored posts and the extent of consumers’ emotional intelligence.

An interactivity analysis of Facebook posts - a case study of the fan page of the Intelligent Ironman Creativity Contest Abstract Facebook is a social networking service launched on February 5, 2004. It also started the new era of media and promotion. However, how to write a post is close related to the effectiveness on interaction with readers. This in term affects the influence of the post. This thesis used data from Intelligent Ironman Creativity Contest, analyzed post time (2 hrs duration in a day), post days (Monday to Sunday), number of words (every 200 words up to 1200), post type (photo, link, Status, video and share video) and post content (evaluative, Informative, entertainment, profitable). The result could be useful guidelines in managing fan page for high school and creativity related activities This research collects 1119 posts from October 1st, 2014 to October 31st, 2018 as samples. We use 110 posts which is the top 10% posts with highest number of like, post, share as the base for quantitative and qualitative analysis. Finally, we examine the content of the top 3% posts and find the common pattern for attract readers. The results show that there is significant effect on post time, post day and post type. But posts with words from 600 to 800 are the most effective than other number of words. When the post types are video and link, short explanation is not enough. If there are action requests, reader costumed phrases or shared memories in the post, the post is very effective in interaction with readers. Key Words：interactivity analysis of Facebook posts, Educational activities, Intelligent Ironman Creativity Contest

Pełny tekst źródłaStreszczenie:
In order to maintain the air fuel ratio within the stoichiometric operating window, which is necessary for efficient catalytic converter operation an accurate estimation of the mass airflow at the engine ports is critical. It is difficult to accurately represent the port air mass flow of an Internal Combustion Spark Ignition engine as reciprocating engines are complex non-linear systems based on a large number of interrelated parameters.
Conventional air fuel ratio control strategies use a number of three dimensional feedforward look up tables to represent these complex nonlinear engine functions. These look up tables are usually functions of only two engine variables, engine speed and engine load. Engine load is either, calculated from the speed density relationship using an absolute manifold air pressure sensor or measured directly using a mass air flow sensor. Conventional AFR control algorithms perform poorly during transient conditions as the strategies inherent in look up tables, are based on stationary or non-dynamic modelling techniques. Modern air fuel ratio control strategies employ a large number of correction factors to compensate for transient engine operation.
This research is a preliminary investigation into the feasibility of using Artificial Neural Networks to represent transient nonlinear engine functions. This research develops offline artificial neural network models of the port air mass flow of a Spark Ignition, based on Hendricks' et al [1] accepted mean value engine model description of the manifold filling phenomena. In particular two different Artificial Neural Network paradigms, namely the Backpropagation algorithm and the fast converging Optimise Layer by Layer algorithm will be trained on data collected through both steady state and transient chassis dynamometer testing.
Both steady state and transient air mass flow models will be developed in this investigation. The accuracy of the Backpropagation and Optimised Layer by Layer models will be analysed both qualitatively and quantitatively and compared in terms of the Root Mean Squared percentage error and computational time in an effort to evaluate the most appropriate model for future online engine implementation.

Porto Editora, one of the oldest and largest educational publishers in Portugal, has had a successful 77 year journey in the forefront of innovation with solid returns and a leading position in the market. Yet, in recent times, it has been reluctant about ushering in disruptive change. Digital technologies are readily revolutionizing the world we live in, as well as the way people learn and teach. As education gradually shifts towards digital solutions, large international players such as Pearson Education, McGraw Hill, etc., have adapted their business models to the new rules of the game, capitalizing on one of the biggest technological and pedagogical trends– Artificial Intelligence and Personalization of Education. But Porto Editora has tended to shy away. This case demonstrates the remarkable transformation of a traditional educational publisher into a modern, forward looking enterprise, which gives the company a sustainable source of competitive advantage. It also illustrates the so-called Innovator’s Dilemma depicting key challenges incumbents encounter in bringing about disruptive change.A Porto Editora, uma das mais antigas e maiores editoras educacionais em Portugal, teve um percurso de 77 anos de sucesso na vanguarda da inovação com retornos sólidos e uma posição de liderança no mercado.

Data visualization, namely dashboards are widely used in helping target audiences such as the ACES and health investigators in the decision-making process. Taking this into consideration, the goal of this study is to elaborate a user-friendly dashboard that reduces the gaps of dashboards provided by the SNS, as well as understand if Spatial Accessibility has a statistical significant effect on the number of consultations in Primary Health Care. This analysis will be performed initially by applying the Pearson’s correlation test, then using the ANOVA and Kruskall-Wallis Test, finally by analyzing the Principal Components. Two mathematical methods were applied to calculate Spatial Accessibility, Two-Step-Floating catchment area method, and supply-to-demand ratio. Based on this study, it comes to light that the spatial accessibility differs between perishes within each county. The farther away the parishes are from the center, the lower the spatial accessibility. This result emerges when the calculation is made considering the supply-to-demand ratio, where the unit is the primary care center, having a statistically significant impact on the number of consultations. The Principal Component Analysis has demonstrated that certain types of consultations are more popular for specific age groups and that some of those age groups are influenced by Spatial Accessibility.A visualização da informação, nomeadamente através dos dashboards, é comumente usada de forma a auxiliar o público-alvo, neste caso, Agrupamentos de Centros de Saúde (ACES ) e investigadores do setor da saúde, no seu processo de tomada de decisão. Tendo isto como base, este estudo tem como objetivo a elaboração de um dashboard com uma interface amiga do utilizador, que colmate as lacunas presentes nos dashboards disponibilizados pelo SNS, assim como verificar se a Acessibilidade Espacial tem um impacto estatisticamente relevante no número de consultas nos Cuidados de Saúde Primários, numa primeira fase recorrendo ao teste de correlação de Perason’s, seguido pela aplicação dos testes ANOVA e Kruskall-Wallis e, por último, procedendo à análise dos Principais componentes. Dois métodos matemáticos foram usados de forma a calcular a Acessibilidade Espacial, nomeadamente, o método Two-Step-Floating catchment area e o rácio supply-to-demand. Através deste estudo foi possível perceber que a Acessibilidade Espacial difere entre freguesias do mesmo concelho, sendo que à medida que as freguesias se afastam do centro do concelho a Acessibilidade Espacial decresce. Esta, quando calculada através do rácio supply-to-demand, em que a unidade são os centros de saúde, tem um efeito estatisticamente relevante no número de consultas. Na Análise dos Componentes Principais, alguns fatores sugerem que certos tipos de consulta são mais utilizados por determinadas faixas etárias, assim como certas faixas etárias são mais influenciadas pela Acessibilidade Espacial do que outras.

No século XXI a governação é um elemento central na vida dos cidadãos e no crescimento das cidades, enquanto espaço entendido como um lugar onde se concentra uma oferta diversificada de serviços (comerciais, industriais, culturais, religiosos, infraestruturas ou de consumo) e que reúne os mais diversos fluxos e atividades humanas. Centramos a investigação no “elemento” cidade, com as suas variadas interpretações ao longo dos tempos, havendo condições expectáveis para alargar o conceito de governação e soberania às regiões e/ou áreas metropolitanas. Quanto à soberania do território a abordagem é mais abstrata, porque se refere a uma entidade, que não conhece nenhuma entidade superior na ordem externa, nem igual na ordem interna. Ora, a soberania do território tem de ser reequilibrada a este nível, já que o digital altera as relações de poder e a limitação do espaço físico confinado às fronteiras. A proposta apresentada, tem como objetivo, validar modelos de Governação em Cidades Inteligentes na aplicabilidade de políticas públicas que conduzam a um reforço da soberania do território, que passará pela criação de novas fronteiras que possibilitem aos Estados a sua reorganização em rede e que garanta ao mesmo tempo a sua sobrevivência, bem como da sua soberania. Uma oportunidade de se entender a evolução do Porto – caso de estudo – ao longo dos últimos anos na perspetiva do planeamento, da gestão demográfica e da governação, ao nível da decisão política, já que a grande aposta europeia, em cidades Smart é, e será uma “janela de oportunidades” para a regeneração da cidade, da sua renovação e até da reabilitação, pois passará por ser uma aposta capacitiva de se auto-sustentarem, aumentando as oportunidades económicas para quem vive e para quem passa pela cidade, minimizando os custos das comunicações, bem como os danos ambientais e ainda a facilidade e acesso à informação.In the twenty-first century, governance is a central element in citizens' lives and in the growth of cities as a place where a diversified range of services (commercial, industrial, cultural, religious, infrastructure and consumer services) is concentrated. The most diverse flows and human activities. We focus research on the "element" city, with its varied interpretations over time, with expected conditions to extend the concept of governance and sovereignty to regions and / or metropolitan areas. As for the sovereignty of the territory, the approach is more abstract, because it refers to an entity, which knows no higher entity in the external order nor equal in the internal order. However, the sovereignty of the territory has to be rebalanced at this level, since the digital one changes the relations of power and the limitation of the physical space confined to the borders. This proposal aims to validate models of governance in smart cities in the applicability of public policies that lead to a reinforcement of the sovereignty of the territory that will pass through the creation of new frontiers that will enable the States to reorganize them into a network and at the same time guarantee their survival, as well as their sovereignty. An opportunity to understand the evolution of Porto - case study - over the last few years in the perspective of planning, demographic management and governance, at the political decision level since the big European bet in Smart cities is and will be, a "window of opportunity" for regeneration of the city, its renovation and even rehabilitation, since it will be a capacitive bet to self-sustain, increasing the economic opportunities for those who live and for those who pass through the city, minimizing the costs of communications, as well as environmental damage, and ease of access to information.
Au XXI siècle, la gouvernance est un élément central de la vie des citoyens et de la croissance des villes en tant que lieu de concentration d'une gamme diversifiée de services (commerciaux, industriels, culturels, religieux, d'infrastructure et de consommation). Les flux les plus divers et les activités humaines. Nous focalisons la recherche sur la ville «élément», avec ses interprétations variées dans le temps, avec les conditions attendues pour étendre le concept de gouvernance et de souveraineté aux régions et / ou zones métropolitaines.Quant à la souveraineté du territoire, l'approche est plus abstraite, car elle fait référence à une entité qui ne connaît aucune entité supérieure dans l'ordre extérieur ni égale dans l'ordre interne. Cependant, la souveraineté du territoire doit être rééquilibrée à ce niveau, puisque le numérique change les rapports de pouvoir et la limitation de l'espace physique confiné aux frontières.Cette proposition vise à valider les modèles de gouvernance pour les villes intelligentes dans l'application des politiques publiques qui conduisent à un renforcement de la souveraineté du territoire qui nécessitera la mise en place de nouvelles frontières qui permettent aux États de la réorganisation du réseau et en garantissant en même temps son la survie, ainsi que leur souveraineté.Une opportunité de comprendre l'évolution de Porto - étude de cas - au cours des dernières années dans la perspective de la planification, de la gestion démographique et de la gouvernance, au niveau décisionnel politique puisque le grand pari européen dans les Smart cities est et sera, une «fenêtre d'opportunité» pour la régénération de la ville, son renouvellement et à la réhabilitation, tout comme étant un pari capacitif autonome, l'amélioration des possibilités économiques pour ceux qui vivent et ceux qui traversent la ville, tout en minimisant les coûts de les communications, ainsi que les dommages environnementaux et la facilité d'accès à l'information.

Perçus pendant longtemps comme faisant parti d'un secteur d'activité économique archaïque, les terminaux portuaires de conteneurs constituent un maillon important et méconnue de plusieurs chaînes de transport intermodal. La croissance rapide des volumes de conteneurs manutentionnés dans ces terminaux a pour conséquence d'entraîner une congestion de ceux-ci et, par le fait même, une perturbation des réseaux d'approvisionnements de plusieurs entreprises. En conséquence, l'objectif de ce mémoire peut être divisé en deux temps. Dans un premier temps, la première partie de ce mémoire vise à comprendre le fonctionnement et les problématiques liées à la gestion des terminaux portuaires de conteneurs. Pour ce faire, une revue de la littérature liée à la planification et la gestion des terminaux portuaires de conteneurs est effectuée, ainsi qu'une étude des processus de ces terminaux. Dans un second temps, ce mémoire vise à proposer des pistes de solutions afin de faciliter la transition des conteneurs dans ces terminaux. La principale piste de solution identifiée est l'application des systèmes de transport intelligents aux terminaux portuaires de conteneurs. Dans ce sens, une étude comparative de l'utilisation des systèmes de transport intelligents entre les ports de la côte est canadienne et les ports du reste du monde est présentée. Ensuite, une première version d’un simulateur des opérations d’un terminal portuaire de conteneurs est développée, afin d'être utilisée comme outil d'analyse pour mesurer l'impact d'une introduction plus importante des systèmes de transport intelligents dans les terminaux portuaires de conteneurs.

Orientação: Óscar Conceição de SousaA Inteligência emocional é a interação entre o estado cognitivo e as emoções de modo a capacitar o sujeito a se adaptar de forma adequada perante o meio. A partir do modelo de ramificação de Mayer que divide as competências e habilidades de Inteligência Emocional em quatro domínios: a) percepção e expressão de emoções, b) assimilação de emoções, c) compreensão e análise das emoções e d) gestão de emoções, tem-se a construção das cinco competências básicas da inteligência emocional: a) autoconsciência, b) gestão das emoções, c) automotivação, d) empatia e e) gestão de emoções em grupos que compõem a Inteligência emocional. Estas competências foram avaliadas por este trabalho visando investigar o desenvolvimento da inteligência emocional entre os professores da educação básica na rede publica e na rede privada de ensino da cidade de Porto Seguro, na Bahia, Brasil. A amostra, composta 120 professores da educação básica distribuídos na rede pública e na rede privada de ensino, respondeu à Escala Veiga Branco para competência emocional em professores. A escala é composta por 15 itens e foi desenhada com o objetivo de conhecer as atitudes que identificam as cinco competências emocionais dos professores, a partir do constructo teórico da inteligência emocional de Golemam (1995) distribuído em 85 fatores totais da escala. Os resultados apontam para um nível mediano de inteligência emocional entre os professores, não existindo diferenças significativas entre professores da rede pública ou da rede privada, bem como para a não existência de diferenças significativas entre professores que atuam na educação infantil, no ensino fundamental e ensino médio. Tais resultados apontam para um desenvolvimento mais elevado em alguns fatores que compõe cada competência, evidenciando uma clara necessidade de um trabalho de intervenção visando uma formação para o maior desenvolvimento da inteligência emocional na profissão docente.
Emotional Intelligence is an interaction between the cognitive function and the emotions adapting the person at the environment: Mayer’s model divide EI in four possibilities a) perception and expression of emotions, b) assimilation of emotions, c) understanding and analysis of emotions, D) managing emotions, for the other side in theses theory has five competences a) selfawareness, b) emotions management, c) self motivation, d) empathy and e) manage emotions in groups. The goal of this research was evaluation the EI with teachers from Porto Seguro – Ba. These teachers work in public and private elementary school in this city. For this study, applied 120 questionaries with teachers from elementary school in Porto Seguro. The questionnaires propose the Veiga Branco Scale for investigate the emotional competences in teachers. The scale is composed by 15 factors and was created with the goal to identify the five emotional competences of the teachers, using the Goleman’s (1995) theory for understand the emotional intelligence. Goleman’s theory propose understand 85 factors in the scale. It results shows that no have differences between teachers from private schools or public schools. They shows no have to important differences between the teachers from child education, elementary and middle schools. These results show for us that have a higher development in some factors that compose each competence, but the demonstrate to a important need for the researcher propose a formation for theses teachers. This formation can help the teachers to develop the Emotional intelligence in yours networks.

Visual perception is a psychological construct that describes the awareness of visual sensations and arise from the interactions of the individual or observer in the external environment together with the physiology of the observer’s visual system. A variety of theories of the development of visual perception have led to the development of different psychometric measures aimed at quantifying the cognitive construct. The Visual Perceptual Aspects Test was developed by Clutten (2009) to measure nine different constructs of visual perception. The original VPAT was validated using content and construct validity based on a Western Cape sample. However, to the researcher’s knowledge, a factor analysis had not yet been conducted on the VPAT to determine the factor validity of the test. Furthermore, no measures of validity or reliability had been conducted on the VPAT using a sample outside of the Western Cape. The aim of this research is to validate the hypothesised nine factor structure of the Visual Perceptual Aspects Test, using a confirmatory factor analysis, exploratory structural equation model, a bifactor confirmatory factor analysis and a bifactor exploratory structural equation model. The results of the analysis showed marginal model fit of the VPAT with the sample data, with sufficient levels of reliability for certain sub-tests. However, the VPAT did not meet significant levels of validity or reliability of the proposed model structure of the VPAT for the sample group of learners based in the Eastern Cape.Psychology
