Abstract:
This dissertation consists of five submission-ready accepted/submitted papers that address some of the key supply chain problems. Supply chain problems, in terms of the area that they address, can be classified into four major groups: location-allocation problem, transportation problem, manufacturing problem, and inventory problem. In this dissertation, location-allocation and location-routing problems, also called LRPs, are studied using two approaches. In the first approach, presented in Chapters 2 and 3, it is assumed that the value of some parameters of the network are dynamically changing. The objective here is to minimize the total system cost by finding the best location-allocation and routing plan when demand and travel times are dynamic. The dynamic nature of demand/travel time is presented by functions obtained from historical data. In the second approach, the sustainability perspective of the LRP is considered. The objective here is also to minimize the total network cost. However, the total cost is presented in terms of energy cost because of the lack of literature investigating the energy effectiveness of a location-routing plan. Traditionally, the objective function of the LRP is expressed in terms of distance minimization, although distance is not the only factor that contributes to energy consumption in an LRP. This perspective is thoroughly discussed in chapters 4 and 5. Due to the rising price of fuel, industries are concerned more than ever about their transportation costs and modes. In the current economic atmosphere, railway transportation is extremely in demand. Hence, to continue the sustainability part of this dissertation, a rail freight transportation system is investigated. The objective here is to develop a heuristic algorithm that can provide a cost-effective train scheduling plan in a matter of seconds. The main contribution in this section is the integration of a pool of business cost elements and constraints existing in practical train-scheduling problems for obtaining results.

Abstract:
Les réseaux 5G et IoT face à une explosion de la demande, deviennent plus complexes et difficiles à gérer. L’automatisation est limitée et les interventions humaines génèrent des erreurs. Côté forums, l’orchestration, les contrôleurs SDN, et la virtualisation réseau introduisent une dynamicité partielle. Côté recherche, la personnalisation impose agilité et intelligence. Cependant, l’orchestration est monolithique. La dynamicité et l’autonomie relatives au « ondemand » ne sont pas assurées. Aussi, face à ces nouveaux défis, nos contributions tentent de répondre à ces besoins. Notre première proposition, architecturale et organisationnelle introduit une couche pour concevoir et gérer les réseaux virtuels. Notre orchestration est distribuée sur 5 couches afin de garantir autonomie et performances. Notre seconde proposition, fonctionnelle, supportée par une simulation, adresse la dynamicité des services « on-demand ». Notre dernière proposition soutenue par une analyse numérique, est une fonction d’aide à la décision, basée sur le SLA de haut niveau afin d’améliorer le ratio de services allouables. Face à ces besoins d’autonomie, de dynamicité, et d’intelligence du nouvel écosystème, notre recherche vise le graal du « zero-touch »
5G and IoT networks face an explosion in demand, and therefore become more complex and difficult to manage. Automation is limited and human intervention generates errors. On the standardization side, orchestration, SDN controllers, and network virtualization introduce partial dynamicity. On the research side, user centric services require agility and intelligence. However, the orchestration is monolithic. The dynamicity and autonomy relating to “on-demand” are not guaranteed. Thus, after 20 years of experience in the telecom industry, our contributions attempt to meet these new challenges. Our first architectural and organizational proposal introduces a new layer to design and manage virtual services. Our orchestration is distributed over 5 layers to guarantee autonomy and performance. Our second proposal, functional, supported by a simulation, addresses the dynamicity of “ondemand” services. Our last proposal supported by a numerical analysis, is a decision-making function, based on the high-level SLA in order to improve the ratio of allowable services. Faced with these needs of autonomy, dynamicity, and intelligence of the new ecosystem, our research aims at the holy grail of "zero-touch"

Abstract:
Actuellement on assiste à une émergence des applications des systèmes embarqués destinées à un large public d'utilisateurs. Ces applications sont de plus en plus complexes et diversifiées. Elles nécessitent une capacité de calcul accrue et doivent satisfaire, dans leurs exécutions, la prise en compte du temps réel. De plus, ces systèmes sur puce fonctionnent dans des conditions souvent difficiles et perturbantes. Ainsi, certaines contraintes temporelles, contraintes de ressources, contraintes de précédence ainsi que d'autres caractéristiques des systèmes généraux peuvent changer au cours d'exécution. Pour respecter leurs contraintes, ces systèmes doivent être capables de supporter la nature dynamique du monde réel depuis la modélisation de l'application jusqu'à son implémentation sur la plateforme d'exécution. Dans cette thèse une nouvelle approche combinant la modélisation haut niveau et l'ordonnancement sur une architecture reconfigurable dynamiquement de nouveau type, a été proposée. Cette approche est originale depuis ça conception en ciblant des applications fortement dynamiques et flexibles. De plus, l'ordonnanceur ainsi développé intègre un nouveau service qui est responsable de la prédiction des variables dynamiques afin d'aboutir à une meilleure exploitation de l'architecture et meilleure performance d'exécution. Des expérimentations ont été présentées sur des applications temps réel.

Abstract:
This study has the objective of identifying the possible environmental constraints that has role for the continuous loss of heathland plant Genista pilosa. The study has assessed different environmental settings where the plant occurs by way of overlaying analysis based on multiple spatial data sets. Thereafter empirical change detection analyses on the land use of the study area have been performed on the GIS environment by combining temporal based remotely sensed spatial data. The result was then analyzed using land use dynamicity model and the rates of change on each land use type are identified. Expansion of human activity, especially the spreading of agricultural land and urbanization, is found to be the most determinant factor for the dramatic loss of the plant. Finally serious attention for the protection of the plant is recommended by mentioning the possible problem that would occur due to a loss of biodiversity.

In the framework of foreign language teachers’ formation, studies points out that beliefs can influence teachers’ actions in the classroom and also that these professionals may recall their experiences as language learners in order to make decisions. Therefore, the identification of possible beliefs and the reflection about them are required steps to a better comprehension of the learner. According to Almeida Filho (1993), the beliefs are part of the Global Operation in the language teaching. Following the same thoughts, Barcelos (1995, 2001, 2004a/b, 2006) contributed to the consolidation of the concept of beliefs in Brazil. The present work aims to identify the beliefs about learning and teaching Spanish from students who are beginning the Language’s degree in Portuguese/Spanish, as well as to verify if there were any changes in relation to these beliefs during this research. Considering the qualitative and interpretative aspect of this research, it was used, as methodology, a mixed questionnaire, an autobiographical production and a semi-structured interview. Through these instruments, it was possible to observe the beliefs’ dynamicity. The results indicate a modification in relation to the belief of a supposed facility that Brazilians have to learn Spanish (Kulikowski & González, 1999). The data of this work also presents changes in the view of language as a list of words to be learned, which seems to be modified, prevailing cultural aspects in the language learning. Regarding to teaching, it was acknowledged beliefs related to the image of a good Spanish teacher and to the foreign language classes. The models mentioned by the participants are, largely, influenced by the classes at university and not by their experiences from the Elementary and High school. The study reveals the dynamic and heterogeneity aspect of the beliefs developed by the learners, who demand from their teachers’ professor/trainer a constant critical and reflective acting.
No contexto da formação de professores de língua estrangeira, estudos apontam que crenças podem influenciar suas ações em sala de aula e que estes profissionais podem se basear em suas experiências como aprendizes de línguas para tomar decisões. Portanto, a identificação de possíveis crenças e a reflexão sobre elas são passos necessários para a compreensão do aprendiz. Para Almeida Filho (1993) as crenças são parte da Operação Global de Ensino de Línguas. Assim como ele, Barcelos (1995, 2001, 2004a/b, 2006) contribui para a consolidação do conceito de crenças no Brasil. O presente trabalho teve como objetivos identificar as crenças sobre aprender e ensinar espanhol de estudantes ingressantes do curso de licenciatura em Letras Português/Espanhol, bem como verificar se houve mudanças em relação a tais crenças durante a pesquisa. Considerando a natureza qualitativa e interpretativista desta investigação, utilizamos um questionário misto, uma produção autobiográfica e uma entrevista semiestruturada. Por meio destes instrumentos, pudemos verificar a dinamicidade das crenças. Os resultados obtidos indicam mudança em relação à crença da suposta facilidade do brasileiro em aprender espanhol (Kulikowski & González, 1999). Os dados deste trabalho também apresentam mudanças na visão de língua como uma lista de palavras a ser aprendida que parece estar sendo modificada, prevalecendo aspectos culturais na aprendizagem do idioma. Quanto ao ensino, identificamos crenças relacionadas à imagem do bom professor de espanhol e às aulas de língua estrangeira sendo que os modelos citados pelos participantes são, em grande parte, influenciados pelas aulas na universidade e não nas experiências tidas no ensino fundamental e médio. A pesquisa desenvolvida constata a dinamicidade e a heterogeneidade das crenças desenvolvidas pelos aprendizes, que demandam do formador de professores uma constante atuação crítico-reflexiva.

This work aims at encouraging the reading or rereading of tales such as Um homem c?lebre , Cantiga de esponsais , Terps?core , Trio em l? menor , O machete , and Marcha f?nebre from the Brazilian writer Joaquim Maria Machado de Assis, hoping to find in them the manifestations of musicality, which is understood, from the viewpoint of contemporary musical theories, as dinamicity indications resulting from the melopaico (melodious verse) stimulus to the understanding of words and/or images, which are inserted in the writing static body from the literary procedures transferring to the text specific characteristics from other arts, such as music, poetry, performatic dance e theater. Such procedures, which are reflected in the writing as a product of Machado s close repertory, often favor, through the fiction, the delineation of the musical context from Rio de Janeiro in the 19th century, as well as the social implications that the transformations of the musical scene impose on the subjectivity constitution

Abstract:
The majority of cognitive scientists today view the mind as a computer, instantiating some function mapping the inputs it gets from the environment to the gross behaviors of the organism. As a result, the emphasis in most ongoing research programmes is on finding that function, or some part of that function. Moreover, the types of functions considered are limited somewhat by the preconception that the mind must be instantiating a function that can be expressed as a computer program. I argue that research done in the last two decades suggests that we should approach cognition with as much consideration to the environment as to the inner workings of the mind. Our cognition is often shaped by the constraints the environment places on us, not just by the "inputs" we receive from it. I argue also that there is a new approach to cognitive science, viewing the mind not as a computer but as a dynamical system, which captures the shift in perspective while eliminating the requirement that cognitive functions be expressable as computer programs. Unfortunately, some advocates of this dynamical perspective have argued that we should replace all of traditional psychology and neuroscience with their new approach. In response to these advocates, I argue that we cannot develop an adequate dynamical picture of the mind without engaging in precisely those sorts of research and hypothesizing that traditional neuroscience and psychology engage in. In short, I argue that we require certain types of explanations in order to get our dynamical (or computational) theories off the ground, and we cannot get those from other dynamical (or computational) theories.

Abstract:
La réutilisation des services pour prendre en charge de nouveaux processus métier, en plus de l'alignement de l'informatique sur les fonctions métier, constitue une motivation clé pour l'utilisation de l'architecture orientée services (SOA) pour le développement de solutions métier. Dans une architecture orientée services, il est important de faciliter la sélection, la configuration et la composition des services existants pour faire face aux changements d’exécution ou à l’évolution des besoins des utilisateurs finaux. Contrairement aux autres systèmes logiciels traditionnels, le comportement dynamique des systèmes basés sur les services nécessite des informations de qualité de service (QoS) actualisées pour assurer une gestion appropriée dans les différentes étapes du cycle de vie. Les entreprises doivent connaître les performances des services Web et des processus métier pour préserver leur pérennité en matière de réutilisation des services. Les trois principaux avantages de la réutilisation des services sont l'amélioration de l'agilité des solutions en assemblant rapidement de nouveaux processus métier à partir des services existants pour répondre aux besoins changeants du marché, réduire les coûts en ne développant pas de nouveaux services pour activer des fonctions métier similaires dans plusieurs processus métier, mais également le déploiement et la gestion des services dans les environnements d'exécution tout au long du cycle de vie SOA. Cependant, il existe actuellement de nombreux défis liés à la durabilité et à la gouvernance du comportement des services pendant son cycle de vie. Parmi ces défis, on peut citer le niveau de performance, la persistance des exigences et l'adaptabilité du service. De plus, il existe certaines limites des outils de surveillance. Ils manquent d’anticipation dans la détection des problèmes et ils sont passifs et ne sont ni réactifs ni prédictifs. Cette thèse porte sur l’évaluation et les recommandations en matière de performance et de gouvernance des systèmes d’information pour suggérer la réutilisation des services au cours de son évolution. L'objectif est de maintenir la durabilité, la robustesse, l'adaptabilité, la réutilisabilité et l'évolutivité des systèmes d'information. À cette fin, nous évaluons les performances de l'architecture orientée service. Il existe plusieurs solutions de surveillance existantes conçues pour prendre en charge une couche spécifique de SOA. En particulier, BAM est un outil de surveillance des activités commerciales permettant de surveiller le flux de données pour les processus métier. Cependant, la surveillance BAM ne fournit pas l'évaluation des performances pour recommander des services et des processus à réutiliser. Il existe très peu d'approches prenant en charge la surveillance des couches SOA. De plus, les solutions sont partiellement dynamiques avec une aide à la décision limitée. Par conséquent, nous proposons une aide à la décision basée sur la performance pour une architecture orientée services. Il se compose de quatre couches en tant que couches de spécification, de gestion des données, d'exploration de données et de décision. La couche de spécification identifie les exigences de l'utilisateur final et les traite via l'ontologie proposée. La couche de données analyse les indicateurs techniques conformes aux normes de qualité les plus récentes, ISO 25010. Les caractéristiques de qualité sont liées à l'efficacité des performances, à la fiabilité et à la réutilisation. La couche d'exploration de données génère des décisions spécifiques basées sur des instances de service en appliquant les algorithmes d'apprentissage automatique. Il utilise les concepts ontologiques proposés et les règles d'inférence sémantique du service, des processus métier, des couches serveur et d'intégration. La couche d'exploration de données renvoie aux ontologies avec ces décisions spécifiques où des règles plus raffinées ont été générées
Reuse of services in supporting new business processes, in addition to alignment of IT with business functions, is a key motivation in using Service-Oriented Architecture (SOA) for developing business solutions. In a service-oriented architecture, it is important to smooth the selection, configuration and composition of existing services to deal with the runtime changes or the evolution of End User requirements. In contrast to other traditional software systems, the dynamic behavior of service based systems requires up-to-date quality of service (QoS) information for its proper management in the different stages of the lifecycle. Organizations need to know the performance of Web services and business processes to maintain their sustainability for reuse of services. The three key benefits of service reuse are improving agility of solutions by quickly assembling new business processes from existing services to meet changing marketplace needs, reducing cost by not developing new services for enabling similar business functions across multiple business processes, but also spanning service deployment and management in runtime environments throughout the SOA lifecycle. However currently, there are many challenges related to the sustainability and governance of service behavior during its lifecycle. Among those challenges, one can mention level of performance, persistence of the requirements and adaptability of the service. Moreover, there are some limitations of monitoring tools. They lack of anticipation in problem detection, and they are passive and neither reactive nor predictive. This thesis focuses on providing assessment and recommendations for performance and governance of information systems for suggesting service reuse during its evolution. The aim is to maintain sustainability, robustness, adaptability, reusability and evolvability of information systems For this purpose, we evaluate the performance of service oriented architecture. There are several existing monitoring solutions designed to support a specific layer of SOA. Particularly, BAM is a business activity monitoring tool for monitoring the flow of data for business processes. However, BAM monitoring do not provide the performance evaluation for recommending services and processes to reuse. There are very few approaches that support monitoring of SOA layers together. Furthermore, the solutions are partially dynamic with limited decision support. Therefore, we propose performance based decision support for service oriented architecture. It consists of four layers as specification, data management, data mining and decision layers. The specification layer identifies the requirements from the End User and process through the proposed ontology. The data layer analyzes technical indicators that are compliant to the latest quality standard, ISO 25010. Quality characteristics are related to performance efficiency, reliability and reusability. The data mining layer generates specific decisions based on service instances by applying the machine learning algorithms. It uses the proposed ontological concepts and semantic inference rules of service, business process, server and integration layers. The data mining layer returns back to ontologies with these specific decisions where more refined rules have been generated from new ontological concepts. The decision layer processes these results and generates a global decision in terms of recommendations. It provides multi-viewpoints decision to reuse existing services or suggesting their composition. To motivate the proposition of this approach, we illustrate the implementation of the proposed algorithms for all the four layers by a business process use case and data set of public repository of shared services. The output of our system is recommendation for reuse of atomic service, composite service and resource allocation provisioning. We ensure the sustainability, adaptability

Abstract:
Cette these aborde, d'un point de vue algorithmique, le probleme lie aux calculs et a la representation des modeles d'une formule de la logique propositionnelle. Notre approche est fondee sur les diagrammes de decision binaire (bdd). Ils permettent de representer facilement l'ensemble des modeles et d'y gerer l'incrementalite. Le premier travail propose dans ce memoire est une etude sur des ordres pour l'insertion de formules particulieres de la logique propositionnelle dans un bdd. Pour cela, nous proposons deux actions complementaires, la premiere pour reduire la taille du bdd (ordre sur les variables de la formule) et la seconde pour reduire le temps de calcul (strategie pour l'insertion). Ceci nous a permis de determiner certaines limites pour l'utilisation des bdd. Dans un second temps, nous proposons d'etendre le formalisme des formules a traiter afin de pouvoir prendre en compte la dynamicite dans les bdd. L'ajout de formules ne posant pas de probleme grace aux bdd, notre extension porte sur le maintien de la coherence lors de l'ajout ou de la suppression de formules. Nous proposons de resoudre le probleme a l'aide d'un codage judicieux et presentons comment appliquer ces travaux dans le cadre des problemes de satisfaction de contraintes dynamiques. Un impliquant premier peut etre vu comme la representation d'un ensemble de modeles. Une extension naturelle de nos travaux, nous a conduit a elaborer un algorithme de calcul et de gestion des impliquants premiers. Nous montrons ici, comment l'effectuer avec un couplage entre un algorithme enumeratif et un bdd. Des experimentations sont presentees pour illustrer et comparer les differentes approches proposees dans cette these.

Contrairement au déploiement d'applications sur une infrastructure centralisée, le déploiement sur une grille nécessite de nombreuses tâches pénibles pour l'utilisateur. La sélection des ressources, le transfert des programmes ainsi que la surveillance de l'exécution sont en effet laissés à sa charge. Aujourd'hui, de nombreux travaux proposent d'automatiser ces étapes dans des cas simples. En revanche très peu permettent de prendre en charge des déploiements plus complexes, comme par exemple le redéploiement d'une partie de l'application pendant son exécution ou encore le déploiement coordonné de plusieurs applications.

Dans cette thèse, nous proposons un modèle pour prendre en charge le déploiement dynamique des applications sur les grilles de calcul. Ce modèle vise à offrir deux fonctionnalités principales. La première consiste en la traduction d'actions de haut niveau, spécifiques aux applications, en opérations de bas niveau, relatives à la gestion des ressources sur la grille. La deuxième consiste en la pré-planification des déploiements, redéploiements et codéploiements d'applications sur les ressources physiques.

Le modèle satisfait trois propriétés. Il rend transparent la gestion des ressources à l'utilisateur. Il offre des actions spécifiques aux besoins de l'application. Enfin, il est non-intrusif en limitant les contraintes sur le modèle de programmation de l'application.

Une proposition d'architecture nommée CORDAGE vient illustrer ce modèle pour le co-déploiement et le redéploiement d'applications. CORDAGE a été développé en lien avec l'outil de réservation OAR et l'outil de déploiement ADAGE. La validation du prototype s'est effectuée avec la plate-forme pair-à-pair JXTA, le service de partage de données JUXMEM ainsi que le système de fichiers distribué GFARM. Notre approche a été évaluée sur la grille expérimentale GRID' 5000.

Abstract:
Une application à base de services est construite à partir d'activités ; chaque activité correspond à un appel (par le biais d'une infrastructure de communication) à une fonction exportée par un service existant. Les activités sont coordonnées par un plan précisant les instructions à réaliser. Pour sécuriser de telles applications à base de services, les travaux actuels se focalisent sur la sécurité au niveau des services utilisés et au niveau de la communication entre ces services. Cependant, les mesures de sécurité à ces niveaux se gèrent mal au niveau du plan de coordination. Cette thèse concerne la coordination sécurisée pour la sécurité des applications à base de services. Elle considère un niveau de sûreté de fonctionnement pour (i) les activités d'un plan de coordination ; (ii) les données échangées entre services ; et (iii) les fonctions de services à appeler. La coordination sécurisée est définie à partir de trois concepts clés : (i) les activités à exécuter avec certaines propriétés dans le cadre de la coordination sécurisée, (ii) les contraintes associées aux activités régissant différents aspects considérés de la coordination sécurisée ; et (iii) les journaux de coordination construits à base de preuves d'exécution des activités. Un plan de coordination sécurisée d'activités est donc décrit sous forme d'un ensemble d'activités dont les contraintes devant être satisfaites sont définies par des formules logiques bien formées, correctement associées, cohérentes et évaluables. L'exécution d'un tel plan correspond à exécuter ses activités en évaluant les contraintes. Elle consiste également à évaluer si les appels aux fonctions de différents services se sont bien passés. L'exécution d'un plan peut s'adapter aux nouveaux besoins et aux changements (de propriétés, de contraintes, d'évaluateurs de contraintes, etc. ) intervenant lors de l'exécution même du plan. Les contributions majeures de la thèse portent sur la définition d'un modèle pour la description de plan de coordination sécurisée d'activités, d'un modèle d'évaluation dynamique de ces plans et d'un canevas logiciel qui supporte la spécification, la transformation, l'exécution et la gestion des plans
Service-based application is built out of activities; each activity corresponds to an invocation (through a communication infrastructure) of an existing service's function. Activities are coordinated by a plan specifying the instructions to be realized. To secure such applications, current works consider the security at the service level and at the service communication level. However, security measures at these levels are mapped inadequately at the coordination level. This thesis focuses on the secure coordination for securing service-based applications. We consider a functional safety level for (i) activities of a coordination plan; (ii) data exchanged between services; and (iii) functions of services to be invoked. Secure coordination is defined through three key concepts: (i) activities to be carried out with certain properties in the scope of coordination plan, (ii) constraints associated with the activities, which control various considered aspects of the plan; and (iii) coordination logs, built from the execution proofs of activities. A secure coordination plan is described as a set of activities, whose constraints to be satisfied are well formed formulas, correctly associated, coherent and evaluable. Execute such a plan corresponds to execute activities by evaluating the constraints. It also consists in evaluating if the services' functions invocations are well done. The plan execution can adapt to the new requirements and changes (of properties, constraints, of constraint solvers, etc. ) interfering at the execution time. This thesis contributes a description model of secure coordination plans; a dynamic evaluation model of these plans and a framework which supports the specification, the transformation, the execution and the management of these plans

Peace pdl handles the first problem by following a goal oriented approach for software processes modelling and enaction. We present, in this dissertation, how this approach is used for supporting the dunamic aspects of software processes and how the logical paradigm facilitates its implementation. Peace pdl handles the second problem by using a nonmonotonic modal logics. The incomplete and uncertain information is modeled, in peace pdl, by means of a logic modal operator in terms of beliefs.

Full text
Abstract:
This thesis aims to show that Coleridge's thinking about science was inseparable from and influenced by his social and political concerns. During his lifetime, science was undergoing a major transition from mechanistic to dynamical modes of explanation. Coleridge's views on natural philosophy reflect this change. As a young man, in the mid-1790s, he embraced the mechanistic philosophy of Necessitarianism, especially in his psychology. In the early 1800s, however, he began to condemn the ideas to which he had previously been attracted. While there were technical, philosophical and religious reasons for this turnabout, there were also major political ones. For he repeatedly complained that the prevailing 'mechanical philosophy' of the period bolstered emerging liberal and Utilitarian philosophies based ultimately on self-interest. To combat the 'commercial' ideology of early nineteenth century Britain, he accordingly advocated an alternative, 'dynamic' view of nature, derived from German Idealism. I argue that Coleridge championed this 'dynamic philosophy' because it sustained his own conservative politics, grounded ultimately on the view that states possess an intrinsic unity, so are not the product of individualistic self-interest.

The subject-matter of this thesis is the role played by movement and contact in the processes of communication. The present research proposes the hypothesis that movement is information and perception, which turns the body into a Corpusmedia (the body as a communication medium). The close relationship between movement and contact plays a fundamental role in the developmental processes of the organism. In order to understand how the body is implied in communication, research on this matter must take recourse to the cognitive sciences. In order to sustain that movement is information and perception, it is necessary to explain the relations and implications of movement and contact within information networks and bodyenvironment communication. The aim of this research is to understand movement and contact as language in a non hierarchic information and communication network, bound to compromise a new epistemology as a applied science of the body. Within the Communication and Semiotic Program at the São Paulo Catholic University, semiotic theories, cognitive science and sciences of complexity are theories of excellence and the most appropriate field to comprehend this phenomena and form the theoretical frame of reference. Corpusmedia, designed to cover all the communication processes, developped both by Phd Professors Christine Greiner & Helena Katz, is the foundation to approach the body within the field of communication, as presented herein. This endeavor is the basis upon which the necessary conditions arise to carry out research on the body within the communication field. With the Semiotic concept of Corpusmedia, the technical term mídia differs from its common meaning. The medium and midiatic concepts in the information society many times reproduce in their core the bodymachine metaphor, which is so widely disseminated in Mass Media consumption society. According to this metaphor understanding of the communication processes sustain a mechanicist, dualist and reductionist view, one which fails to explain all the body-environment processes. The need to focus the question of movement and contact on communication, derives from the fact that available literature on this issue approaches the body as an information-processing machine. The present study sustains that by regarding the body as Corpusmedia, we escape from dualistic formulations and from those which imply that the body is disposable and replaceable, since it is considered as an object and a reproducer under the body-machine metaphor. The point here is to approach the body as a producer of knowledge. This research, starting from theoretical-praxis processes, explored communication through the cognition processes of the body. For this purpose, it was fundamental to count on the theories of neurodarwinism of Gerald Edelman, and the dynamic theory of Esther Thelen. Supported by these views, it was possible to research outside the common nature versus nurture split that gets in the way of understanding communication as an evolutive feature of the body
O foco desta tese é o papel dos movimentos e do contato no campo da comunicação. Defende a hipótese de que movimentos são informações e percepção, e fazem do corpo um corpomídia. A estreita relação entre movimento e contato confere papel fundamental aos processos de desenvolvimento do organismo. Para compreender como o corpo está implicado na comunicação, portanto, é preciso pesquisá-lo no âmbito da cognição. Para sustentar que movimento é informação e percepção, faz-se necessário explicar suas relações e implicações na comunicação corpo-ambiente. O objetivo da pesquisa é entender movimento e contato como linguagem em rede não hierarquizada de informação e comunicação, com o compromisso de uma nova epistemologia de ciência aplicada ao corpo. No contexto do Programa de Comunicação e Semiótica da PUC-SP, as teorias semióticas, as ciências da complexidade e as ciências cognitivas são as mais indicadas à pesquisa e embasam, por isso, o quadro teórico de referência. Propomos então fundamentar a abordagem da pesquisa aqui apresentada com a teoria corpomídia desenvolvida pelas Professoras Doutoras Christine Greiner e Helena Katz, que abrange todos os processos de comunicação social. No conceito semiótico corpomídia, o termo técnico mídia difere da noção do senso comum. Desse empreendimento, surgem as condições necessárias para se realizar investigações sobre o corpo na área da Comunicação. Os conceitos de mídia e midiática da era da informação muitas vezes reproduzem em seu bojo a metáfora corpo-máquina tão disseminada na sociedade de consumo. E sustenta um tratamento para corpo dentro de uma visão mecanicista, dualista e reducionista, que não consegue explicar os processos de comunicação corpo-ambiente. A necessidade de se focar a questão dos movimentos e do contato na comunicação se deve ao fato de a bibliografia disponível na área abordar o corpo a partir da concepção de corpo como um processador-de-informação. Os estudos que encaminham a proposta do corpo como corpomídia permitem escapar das formulações dualistas e daquelas nas tais o corpo é descartável, uma vez que o apresentam como um objeto e reprodutor, debaixo da concepção corpo-máquina. Trata-se aqui de abordar o corpo como produtor de conhecimento. Partindo de processos teórico-práticos, o campo da comunicação foi explorado através dos processos de conhecimento que se estabelecem quando o corpo se comunica. Para tal, foi indispensável contar com os pressupostos teóricos do neurocientista Gerald Edelman e da cientista cognitiva Esther Thelen. Com eles, tornou-se possível trabalhar fora da habitual separação entre natureza e cultura que atrapalha a compreensão da comunicação como um traço evolutivo do corpo

Abstract:
Cette thèse a pour cadre les communications dans les machines paral lèles dans une optique de calcul haute-performance. Les évolutions du matériel ont rendu nécessaire les adaptations des logiciels destinés à exploiter les machines parallèles. En effet, les architectures de type ``grappes'' sont maintenant très répandues et l'apparition des grilles de calcul complique encore plus la situation car l'obtention des hautes performances passe par une exploitation des différents réseaux rapides disponibles et une prise en compte de la hiérarchie intrinsèque des configurations considérées. Au niveau applicatif, de nouvelles exigences émergent comme la dynamicité. Or, ces aspects sont trop souvent partiellement traités, en particulier dans les implémentations du standard de programmation par passage de messages MPI. Les solutions existantes se concentrent sur la hiérarchie et l'hétérogénéité ou la dynamicité, exceptionnellement les deux. En ce qui concerne les premiers aspects, des simplifications conduisent à une exploitation suboptimale du matériel potentiellement disponible. Nous avons analysé des implémentations existantes de MPI et avons proposé une architecture répondant aux besoins formulés. Cette architecture repose sur une for te interaction entre communications et processus légers et son c\oe ur est constitué par un moteur de progression des communications qui permet d'améliorer substantiellement les mécanismes existants. Les deux éléments logiciels fondamentaux sont une bibliothèque de processus légers (Marcel) ainsi qu'une couche générique de communication (Madeleine). L'implémentation de cette architecture a débouché sur le logiciel MPICH-Madeleine, utilisé ou évalué par plusieurs équipes et projets de recherche en France comme à l'étranger. L'évalution des performances (comparaisons avec Madeleine, mesures des opérations point-à-point, noyaux applicatifs) menée avec plusieurs réseaux haut-débit sur des grappes homogènes de machines multi-processeurs et les comparaisons avec MPICH-G2 ou PACX-MPI en environnement hétérogène démontrent que MPICH-Madeleine atteint des résultats de niveau similaire voire supérieur à ceux d'implémentations spécialisées de MPI.

Abstract:
La réussite du lancement d'un grand nombre des satellites Radar à Synthèse d'Ouverture (RSO - SAR) de nouvelle génération a fourni régulièrement des images SAR et SAR polarimétrique (PolSAR) multitemporelles à haute et très haute résolution spatiale sur de larges régions de la surface de la Terre. Le système SAR est approprié pour des tâches de surveillance continue ou il offre l'avantage d'être indépendant de l'éclairement solaire et de la couverture nuageuse. Avec des données multitemporelles, l'information spatiale et temporelle peut être exploitée simultanément pour rendre plus concise, l'extraction d'information à partir des données. La détection de changement de structures spécifiques dans un certain intervalle de temps nécessite un traitement complexe des données SAR et la présence du chatoiement (speckle) qui affecte la rétrodiffusion comme un bruit multiplicatif. Le but de cette thèse est de fournir une méthodologie pour simplifier l'analyse des données multitemporelles SAR. Cette méthodologie doit bénéficier des avantages d'acquisitions SAR répétitives et être capable de traiter différents types de données SAR (images SAR mono-, multi- composantes, etc.) pour diverses applications. Au cours de cette thèse, nous proposons tout d'abord une méthode générale basée sur une matrice d'information spatio-temporelle appelée Matrice de détection de changement (CDM). Cette matrice contient des informations de changements obtenus à partir de tests croisés de similarité sur des voisinages adaptatifs. La méthode proposée est ensuite exploitée pour réaliser trois tâches différentes: 1) la détection de changement multitemporel avec différents types de changements, ce qui permet la combinaison des cartes de changement entre des paires d'images pour améliorer la performance de résultat de détection de changement; 2) l'analyse de la dynamicité de changement de la zone observée, ce qui permet l'étude de l'évolution temporelle des objets d'intérêt; 3) le filtrage nonlocal temporel des séries temporelles d'images SAR/PolSAR, ce qui permet d'éviter le lissage des informations de changement dans des séries pendant le processus de filtrage.Afin d'illustrer la pertinence de la méthode proposée, la partie expérimentale de la thèse est effectuée sur deux sites d'étude: Chamonix Mont-Blanc, France et le volcan Merapi, Indonésie, avec différents types de changements (i.e. évolution saisonnière, glaciers, éruption volcanique, etc.). Les observations de ces sites d'étude sont acquises sur quatre séries temporelles d'images SAR monocomposantes et multicomposantes de moyenne à haute et très haute résolution: des séries temporelles d'images Sentinel-1, ALOS-PALSAR, RADARSAT-2 et TerraSAR-X
A large number of successfully launched and operated Synthetic Aperture Radar (SAR) satellites has regularly provided multitemporal SAR and polarimetric SAR (PolSAR) images with high and very high spatial resolution over immense areas of the Earth surface. SAR system is appropriate for monitoring tasks thanks to the advantage of operating in all-time and all-weather conditions. With multitemporal data, both spatial and temporal information can simultaneously be exploited to improve the results of researche works. Change detection of specific features within a certain time interval has to deal with a complex processing of SAR data and the so-called speckle which affects the backscattered signal as multiplicative noise.The aim of this thesis is to provide a methodology for simplifying the analysis of multitemporal SAR data. Such methodology can benefit from the advantages of repetitive SAR acquisitions and be able to process different kinds of SAR data (i.e. single, multipolarization SAR, etc.) for various applications. In this thesis, we first propose a general framework based on a spatio-temporal information matrix called emph{Change Detection Matrix} (CDM). This matrix contains temporal neighborhoods which are adaptive to changed and unchanged areas thanks to similarity cross tests. Then, the proposed method is used to perform three different tasks:1) multitemporal change detection with different kinds of changes, which allows the combination of multitemporal pair-wise change maps to improve the performance of change detection result;2) analysis of change dynamics in the observed area, which allows the investigation of temporal evolution of objects of interest;3) nonlocal temporal mean filtering of SAR/PolSAR image time series, which allows us to avoid smoothing change information in the time series during the filtering process.In order to illustrate the relevancy of the proposed method, the experimental works of the thesis is performed on four datasets over two test-sites: Chamonix Mont-Blanc, France and Merapi volcano, Indonesia, with different types of changes (i.e., seasonal evolution, glaciers, volcanic eruption, etc.). Observations of these test-sites are performed on four SAR images time series from single polarization to full polarization, from medium to high, very high spatial resolution: Sentinel-1, ALOS-PALSAR, RADARSAT-2 and TerraSAR-X time series

L'approche multi-agent, domaine de l'intelligence artificielle distribuée, ouvre une nouvelle voie pour appréhender de façon naturelle les problèmes de satisfaction de contraintes (Constraint Satisfaction Problems, CSP) souvent abordes par des systèmes centralises et des modèles d'exécution séquentiels. Cette approche a d'abord été utilisée dans le cadre de problèmes d'allocation de ressources (voir annexes). Sous le nom de MASC (approche Multi-Agent des problèmes de Satisfaction de Contraintes), elle a ensuite été étendue au cadre général CSP. MASC est une méthode par déplacements au sein de l'espace d'état, guides par des réparations locales stochastiques. Celles-ci sont basées sur un outil d'optimisation, le recuit simulé, dont l'objectif est d'atteindre un état optimal qui satisfasse le maximum de contraintes. Des résultats théoriques sont établis et discutes. Le problème de l'implémentation sur une architecture parallèle est également soulève et une solution est apportée. Outre cet aspect statique, MASC traite l'aspect dynamique des CSPs par l'intégration d'un mécanisme de réactivations. Ce mécanisme, tout en gardant l'objectif d'optimalité, vise à retrouver une solution proche de la solution de départ. Aussi bien pour l'aspect statique que pour l'aspect dynamique, des résultats expérimentaux sont exhibes et discutes

Abstract:
Předkládaná práce se soustředí na problematiku využívání úzkopásmového rádiového kanálu rádiovými modemy, které jsou určené pro průmyslové aplikace pozemní pohyblivé rádiové služby, specifikované v dominantní míře Evropským standardem ETSI EN 300 113. Tato rádiová zařízení se používají v kmitočtových pásmech od 30 MHz do 1 GHz s nejčastěji přidělovanou šířkou pásma 25 kHz a ve většině svých instalací jsou využívána ve fixních nebo mobilních bezdrátových sítích. Mezi typické oblasti použití patří zejména datová telemetrie, aplikace typu SCADA, nebo monitorování transportu strategických surovin. Za hlavní znaky popisovaného systému lze označit komunikační pokrytí značných vzdáleností, dané především vysokou výkonovou účinnosti datového přenosu a využívaní efektivních přístupových technik na rádiový kanál se semiduplexním komunikačním režimem. Striktní požadavky na elektromagnetickou kompatibilitu umožňují těmto zařízením využívat spektrum i v oblastech kmitočtově blízkým jiným komunikačním systémům bez nutnosti vkládání dodatečných ochranných frekvenčních pásem. Úzkopásmové rádiové komunikační systémy, v současnosti používají převážně exponenciální digitální modulace s konstantní modulační obálkou zejména z důvodů velice striktních omezení pro velikost výkonu vyzářeného do sousedního kanálu. Dosahují tak pouze kompromisních hodnot komunikační účinnosti. Úpravy limitů příslušných rádiových parametrů a rychlý rozvoj prostředků číslicového zpracování signálu v nedávné době, dnes umožňují ekonomicky přijatelné využití spektrálně efektivnějších modulačních technik i v těch oblastech, kde je prioritní využívání úzkých rádiových kanálů. Cílem předkládané disertační práce je proto výzkum postupů směřující ke sjednocení výhodných vlastností lineárních a nelineárních modulací v moderní konstrukci úzkopásmového rádiového modemu. Účelem tohoto výzkumu je efektivní a „ekologické“ využívání přidělené části frekvenčního spektra.

Abstract:
SOFA 2 is a component system employing hierarchically composed components in distributed environment. It contains concepts, which allow for specifying dynamic reconfigurations of component architectures at runtime, which is essential for virtually any real-life application. The dynamic reconfigurations comprise creating/disposing components and creating/disposing connections between components. In contrast to majority of component systems, SOFA 2 is able to specify possible architectural reconfigurations in the application architecture at design time. This allows SOFA 2 runtime to follow the dynamic behavior of the application and reflect the behavior in architectural reconfigurations. The goal of this thesis is to reify these concepts of dynamic reconfigurations in the implementation of SOFA 2 and demonstrate their usage on a demo application.

Abstract:
Anomaly detection can be used to infer the presence of errors or intrusions without observing the target service or application, but detecting variations in the observable parts of the system on which the service or the application resides. This is a promising technique in complex software-intensive systems, where either instrumenting the services’ internals is exceedingly time-consuming, or encapsulation makes them not accessible. Unfortunately, in such systems anomaly detection is often made ineffective due to their dynamicity, which implies changes in the services or their expected workload. The main target of this Thesis is to present our approach to enhance the efficacy of anomaly detection in complex dynamic systems. Evolving and Dynamic systems may often change their behavior, adapting it to the current context, making the characterization of the expected behavior, and consequently the identification of anomalies, a hard challenge. As a result, there are no clear stateof-the-art answers on applying error or anomaly detection in highly dynamic and complex systems, while some frameworks for performing anomaly detection in complex - not highly dynamic - systems have been described in the literature. To contribute filling this gap, we put a promising state-of-the-art solution to work on data flows related to the Secure! system, a Crisis Management System which is structured as a Service Oriented Architecture (SOA). At first, we observed that applying such strategy as it was described for non-dynamic systems does not provide comparable detection scores, therefore we tried to adapt it by i) expanding the data collecting strategy, ii) considering additional information on the system, and iii) performing dedicated tuning of parameters of such strategy. This process led us to a customized version of the basic solution which has comparable scores with respect to other works targeting non-dynamic complex systems. At this point, we conducted an extensive experimental campaign targeting both the Secure! and the jSeduite SOAs based on the injection of specific types of anomalies to substantiate and confirm the progresses we obtained during our process. However, the main result we obtained through these experiments was a precise definition of design guidelines that are mainly related to the necessity of frequently reconfiguring both the monitoring strategy and the detection algorithms to suit an adaptive notion of expected and anomalous behavior, avoiding interferences and minimizing detection overheads. After reporting and presenting these guidelines according to specific viewpoints, we present MADneSs, a framework which implements our approach to anomaly detection that is tailored for such systems. The framework includes an adaptive multi-layer monitoring module. Monitored data is then processed by the anomaly detector, which adapts its parameters depending on the current behavior of the system, providing an anomaly alert. Lastly, we explore possible future implications explicitly targeting Systems-ofSystems, an architectural paradigm which in the recent years has started being adopted when building dynamic complex systems.

Abstract:
This thesis deals with the group of Latin iterative verbs, i.e. the group that is formally marked with the iterative suffix -t. It deals with the question what was the actual meaning of the iterative suffix -t in classical Latin as reference literature says that in some cases the meaning of iterative verbs in classical Latin was the same as that of the base verb and there are iterative verbs whose base verbs are not attested at all. Also, only iterative verbs often passed into Romance languages. Another question this thesis deals with is the relationship of iterative verbs as a group set off on the basis of the category of aktionsart as it is understood in the Czech linguistic tradition and the categories that are generally referred to as aspect (grammatical aspect, lexical aspect). In this case, the selected method is a corpus-based quantitative method called the "behavioural profiles". In our case, the corpus is limited to selected prosaic works of the classical Latin period of approximately the 1st century b.C. to the 1st century AD. In its first part, the analysis is based on studying the occurrences of selected iterative verb - base verb pairs in the above mentioned corpus, especially focused on the frequency of occurrence, valence and classification of predicates into Vendler's classes,...

Joyce, CN. "Created motion in Maximus the Confessor : a dynamicist reading." Thesis, 2010. https://eprints.utas.edu.au/10789/1/front.pdf.

Full text
Abstract:
This thesis explores how Maximus the Confessor understands created motion. It describes how he utilises not just one description of motion, but several. Recent literature has struggled to articulate the diversity of ways for describing motion available to Maximus. Sometimes these works have over-simplified Maximus’ views. At other times the works gesture toward some important areas, but fail to go into sufficient technical detail. This study explores how Maximus’ descriptions of motion play important but specific roles in his work. Accordingly, the thesis employs a strategy of closely reading texts containing key descriptions of motion, clarifying their meaning, and setting out some implications. The work begins by describing Maximus’ cosmological context, and shows the importance of relating different senses of motion together. This suggests the need for more specific analyses. Chapters two and three describe a form of self-continuous motion, showing how it permeates Maximus’ thought. Chapters four and five evaluate two approaches in the secondary literature. Chapter four focuses on motion as a general principle in the cosmos. Accordingly, it explores how the general account of motion emerges from a theology of creation. Chapter five analyses how personhood has been used, with some success, for describing specific instances of motion in Maximus. The sixth and final chapter examines how motion is comprised of several different processes working cooperatively. The thesis does not explicitly investigate how Maximus’ views on motion might be reconstructed in contemporary contexts. Nor does it discuss the broader implications of created motion for his theology. It offers an alternative reading of this important but notoriously difficult figure of antiquity, suggesting new avenues of interpretation, as well as opening a range of topics for further research.

Abstract:
The aim of the thesis is a trajectory optimization of robot in the Ketchup House competition. Environment mapping system is proposed to deal with this issue. As an ideal solution is chosen a method of familiar environment scanning using a camera module and lidar. Camera module and lidar provide a possibility to scan up to nine searched objects, instead of one object allowed by the previous solution. A proximity sensor supplements the whole system, so the efficiency of detection increase. To find a particular position of the object on the playing field, image processing methods are used, namely line detection and thresholding. Moreover, new playing strategy and a new way of representing the playing field are implemented. Robot K4, created by PEF MENDELU AiStorm team, serves for application of the system.

Rozprawa doktorska dotyczy badań z zakresu chemii witaminy E. Głównym założeniem pracy było uzyskanie dokładniejszych informacji o efektach stereoelektronowych, dynamicznych oraz konformacyjnych, występujących w tokoferolach, głównie w pierścieniu dihydropiranylowym. W ramach prowadzonych badań zsyntezowane zostały trzy serie analogów witaminy E do badań spektroskopowych oraz strukturalnych w aspekcie ich aktywności biologicznej, głównie antyoksydacyjnej. W grupie związków modelowych znalazły się analogi α-tokoferolu, modyfikowane w pozycji O-1 oraz C-2. Zsyntezowane zostały nieopisane dotychczas w literaturze 1-karbaanalogi witaminy E zawierające szkielet 1,2,3,4-tetrahydronaftalenu (tetraliny) w miejsce pierścienia chromanu. W drugim wariancie otrzymana została seria analogów α-tokoferolu, zawierających w miejsce długiego łańcucha fitylowego krótszy fragment węglowy (C-1, C-2, C-6) oraz szereg grup funkcyjnych. Trzecią grupę stanowiły nowe analogi 2-desmetylo. Otrzymane związki modelowe zostały zbadane za pomocą spektroskopii NMR (w roztworze oraz ciele stałym). Zbadany został wpływ atomu tlenu O1 oraz podstawników w pozycji C-2 na dynamikę i preferencje konformacyjne układu chroman-6-olu. W celu ilościowego oszacowania stabilizującego wpływu atomu O1 na tworzące się rodniki fenoksylowe przeprowadzono badania aktywności antyoksydacyjnej. Ponadto, zbadany został wpływ 1-karba-α-tokoferolu na właściwości termotropowe modelowych błon fosfolipidowych.
The dissertation concerns the chemistry of vitamin E. The aim of this work was to gain more information about stereoelectronic, dynamic and conformational preferences present in tocopherols, mainly in the dihydropyran ring. For spectroscopic and structural studies, a group of α-tocopherol analogs modified at the O-1 and C-2 position was designed and synthesized. The main goal of the synthetic work was to obtain new vitamin E analogs containing the 1,2,3,4-tetrahydronaphthalene skeleton in place of the chroman ring. As a result of the work, a simple and efficient method of synthesis novel 6-hydroxy-1,2,3,4-tetrahydronaphthalenes has been developed. In the second part of the synthetic work, a series of model compounds with shorter carbon fragment (C1, C2, C6) in a place of the long phytyl chain have obtained. In the last part of the synthetic work new 2-desmethyl analogs were synthesized. The obtained model compounds were investigated using solution and solid-state NMR spectroscopy. The influence of the O1 oxygen atom and the substituent at the C-2 position on dynamics and conformational preferences of the dihydropyran ring have been studied. In order to quantify the influence of the O1 oxygen atom on the stabilization of the phenoxy radicals, studies on the antioxidant activity of selected model compounds were also carried out.
