De l’espace de la scène à l’espace de la page : médiation et médiatisation du corps de mode à travers le défilé et les séries photographiques de la presse magazine / From the catwalk space to the photographic page : mediation and mediatization of fashion-body through the catwalk and the photographic series of magazines

Kireche-Gerwig, Rym 03 October 2016 (has links)
Cette recherche interroge la poétique du corps de mode contemporain à travers deux médias de la figuration du corps : le défilé de mode et les séries photographiques enchâssées dans la presse magazine. Au carrefour d’enjeux sémiotiques, discursifs, politiques et sociaux, la problématique centrale de notre thèse convoque le point de vue complexe et interdisciplinaire des Sciences de l’information et de la communication afin de réfléchir à la construction médiatique du corps de mode. Trois hypothèses qui appréhendent les dispositifs médiatisant le corps de mode et le produisant comme « forme réifiée » publicitaire et culturelle scindent la problématique posée. La première postule que les défilés et les séries mode sont des médias produisant un corps informé par la dimension dispositive propre à chacun d’eux. La seconde pose que si le corps de mode est produit à des fins marchandes et publicitaires, il n’en demeure pas moins « culturalisé » grâce à l’emprunt notamment au chorégraphique conçu comme écriture du corps dans l’espace de la scène du défilé à l’espace de la page photographique, le dotant d’un statut culturel qui lui permet de circuler dans l’espace social. La troisième enfin poursuit le mouvement de réification du corps de mode amorcé par sa médiatisation à travers le défilé en posant que sa mass-médiatisation par les séries photographiques en fait une production industrialisée et standardisée, le rendant semblable à une marchandise. / The present research interrogates the poetry of the fashion contemporary body transmitted by two media portraying the body : fashion shows and photographic series as part of fashion magazines. At the crossroads of semiotic, discursive political and social issues, the central problem investigated in this thesis is the complex and interdisciplinary point of view of the information sciences of communication with the aim to study the media construction of the fashion world. Three hypotheses divide the investigated problem by taking the mediatised part of the fashion world and produce it as “reified form” of advertisement and culture. The first postulates that fashion shows and fashion series are medias which produce an informed body by the apparatus owned by each of them. The second hypothesis postulates that the fashion body is produced for commercialand advertisement purposes. It does not persist less “culturalized” thanks to the choreography which is perceived as writing of the body in the catwalk space or in the photographic page. This gives it a culture status allowing it to circulate in the social medias. Finally, the third follows the movement of the fashion body's reification initiated by the exposure through fashion shows. It postulates that its mass exposure by photographic series, which is an industrialized and standardized production, make it similar to a merchandise.

Contributions to the optimized deployment of connected sensors on the Internet of Things collection networks / Contributions au déploiement optimisé des capteurs connectés dans les réseaux de collecte de l'Internet des Objets

Mnasri, Sami 27 June 2018 (has links)
Les réseaux de collecte de l’IoT soulèvent de nombreux problèmes d'optimisation, à cause des capacités limitées des capteurs en énergie, en traitement et en mémoire. Dans l'optique d’améliorer la performance du réseau, nous nous intéressons à une contribution liée à l'optimisation du déploiement 3D d’intérieur des nœuds sur les réseaux de capteurs sans fil en utilisant des méta-heuristiques hybrides se basant sur des modèles mathématiques multi-objectif. L’objectif principal est donc de proposer des hybridations et modifications des algorithmes d’optimisation dans le but de réaliser le positionnement 3D adéquat des nœuds dans les réseaux de capteurs sans fil avec satisfaction d’un ensemble de contraintes et objectifs qui sont souvent antagonistes. Nous proposons d'axer notre contribution sur les méta-heuristiques hybrides et combinés avec des procédures de réduction de dimentionalité et d’incorporation de préférences des utilisateurs. Ces schémas d’hybridation sont tous validés par des résultats numériques de test. Ensuite, des simulations complétées par; et confrontées à ; des expérimentations sur des testbeds réelles. / IoT collection networks raise many optimization problems; in particular because the sensors have limited capacity in energy, processing and memory. In order to improve the performance of the network, we are interested in a contribution related to the optimization of the 3D indoor deployment of nodes using multi-objective mathematics models relying on hybrid meta-heuristics. Therefore, our main objective is to propose hybridizations and modifications of the optimization algorithms to achieve the appropriate 3D positioning of the nodes in the wireless sensor networks with satisfaction of a set of constraints and objectives that are often antagonistic. We propose to focus our contribution on meta-heuristics hybridized and combined with procedures to reduce dimensionality and to incorporate user preferences. These hybridization schemes are all validated by numerical tests. Then, we proposed simulations that are completed by, and confronted with experiments on real testbeds.

Angažovanost Německa v operacích SBOP: srovnání misí v Demokratické republice Kongo a Libyi / Germany's commitment to CSDP operations: comparing the cases of the DRC and Libya

Westenberger, Kay Louise January 2019 (has links)
This thesis analyses Germany's commitment to multilateral military operations. Following the research question why Germany participates in some multilateral military operations but not in others, Germany's respective decision-making process regarding troop deployment in the DR Congo in 2006 on one hand and military non-engagement in Libya 2011 on the other hand is traced. By contrasting the concept of strategic culture with a purely rational assessment of the factors of alliance politics, risk-analysis and military feasibility of the operations, the decisiveness of taking into account Germany's strategic culture to explain deployment decisions is stressed. Neither is there a lack of external pressure for German military participation in the case of Libya, nor is the military operation in the DR Congo decisively less risky or militarily more feasible. Rather, Germany's multilateral and anti- militaristic strategic cultural strands affect its decision-making. Next to demanding a thorough justification and legitimization of any military engagement, two red lines for military deployment can be identified. First, Germany refuses to act unilaterally and displays a high reluctance towards military engagement outside the multilateral framework of the UN, NATO or EU. Secondly, Germany rejects to engage in...

Approaches to Modularity in Product Architecture

Börjesson, Fredrik January 2012 (has links)
Modular product architecture is characterized by the existence of standardized interfaces between the physical building blocks. A module is a collection of technical solutions that perform a function, with interfaces selected for company-specific strategic reasons. Approaches to modularity are the structured methods by which modular product architectures are derived. The approaches include Modular Function Deployment (MFD), Design Structure Matrix (DSM), Function Structure Heuristics and many other, including hybrids. The thesis includes a survey of relevant theory and a discussion of four challenges in product architecture research, detailed in the appended papers. One common experience from project work is structured methods such as DSM or MFD often do not yield fully conclusive results. This is usually because the algorithms used to generate modules do not have enough relevant data. Thus, we ask whether it is possible to introduce new data to make the output more conclusive. A case study is used to answer this question. The analysis indicates that with additional properties to capture product geometry, and flow of matter, energy, or information, the output is more conclusive. If product development projects even have an architecture definition phase, very little time is spent actually selecting the most suitable tool. Several academic models are available, but they use incompatible criteria, and do not capture experience-based or subjective criteria we may wish to include. The research question is whether we can define selection criteria objectively using academic models and experience-based criteria. The author gathers criteria from three academic models, adds experience criteria, performs a pairwise comparison of all available criteria and applies a hierarchical cluster analysis, with subsequent interpretation. The resulting evaluation model is tested on five approaches to modularity. Several conclusions are discussed. One is that of the five approaches studied, MFD and DSM have the most complementary sets of strengths and weaknesses, and that hybrids between these two fundamental approaches would be particularly interesting. The majority of all product development tries to improve existing products. A common criticism against all structured approaches to modularity is they work best for existing products. Is this perhaps a misconception? We ask whether MFD and DSM can be used on novel product types at an early phase of product development. MFD and DSM are applied to the hybrid drive train of a Forwarder. The output of the selected approaches is compared and reconciled, indicating that conclusions about a suitable modular architecture can be derived, even when many technical solutions are unknown. Among several conclusions, one is the electronic inverter must support several operating modes that depend on high-level properties of the drive train itself (such as whether regeneration is used). A modular structure for the electronic inverter is proposed. Module generation in MFD is usually done with Hierarchical Cluster Analysis (HCA), where the results are presented in the form of a Dendrogram. Statistical software can generate a Dendrogram in a matter of seconds. For DSM, the situation is different. Most available algorithms require a fair amount of processing time. One popular algorithm, the Idicula-Gutierrez-Thebeau Algorithm (IGTA), requires a total time of a few hours for a problem of medium complexity (about 60 components). The research question is whether IGTA can be improved to execute faster, while maintaining or improving quality of output. Two algorithmic changes together reduce execution time required by a factor of seven to eight in the trials, and improve quality of output by about 15 percent. / QC 20120605

A DevOps Approach to the EA Blueprint Architectural Pattern

Persson, Susanna January 2022 (has links)
In the world of software development, there is an increasing demand for software to keep up with rapid changes in its real-world context. A Resilient Digital Twin of an Organization is a type of software whose purpose is to digitally represent an organization or a component of an organization - as a Digital Twin -, and to keep doing so accurately throughout the real-world organization’s changes - a Resilient Digital Twin. An architectural pattern, called the EA Blueprint Pattern, has recently been proposed as a pattern to use for developing Resilient Digital Twins that can change together with the changes in the organization. However, software architecture is not the only factor that enables continuous change and adaptability in software. For software development teams to be able to deliver software rapidly and reliably, the software development process itself must be adapted to allow for frequent and fast changes. From this need, the Agile methodology and subsequently the set of work practises called DevOps has emerged. DevOps leverages automation and fast feedback as tools to facilitate a shorter system development life cycle and continuous delivery. The usage of DevOps is becoming increasingly popular in the software development field. It stands to reason that there is a need to ensure that the EA Blueprint Pattern is appropriate even in a DevOps context, where different tools and routines may be used than in traditional development. To complete this project, a use case of the EA Blueprint Pattern has been moved from a traditionally developed and deployed setting to a DevOps setting that includes essential DevOps tools such as Infrastructure as Code, a cloud environment, and a CI/CD pipeline that enables automatic deployment and therefore a shorter system development life cycle. By doing this, it can be gauged how well the EA Blueprint Pattern is adapted to a modern software development process which utilises the advantages of DevOps.

Migrating to IPv6

Kintu, Zephernia January 2012 (has links)
Today hundreds of millions of users are interconnected by communication channels allowing them to communicate and to share information. These users and the devices that interconnect them are what constitute the Internet. The Internet is a network of networks with a myriad of computer devices, including smartphones, game consoles (handheld/stationary), IP televisions, tablet computers, laptop computers, desktop computers, palmtop computers, etc. This network of computers flourishes because of careful planning and maintenance by Internet Service Providers (ISPs), backbone network operators, and others. An additional factor that enables the Internet to operate is the four logical layers of abstraction in the TCP/IP protocol stack. One of these layers is the layer responsible for the transfer of datagrams/packets from one host to another. This layer is known as the Internet Protocol (IP) layer. However, as originally conceived a 32 bit address was thought to be more than enough. The space of IP addresses was distributed among different regions rather disproportionately, driven largely by the numbers of addresses that were requested (ordered in time). Today after a series of inventions in the field (such as the world wide web) and a rapid growth in the number of devices that wish to connect to the Internet the available unassigned address space has largely been depleted. Regions with large populations, but with few assigned blocks of IP addresses have begun to exhaust all their assigned addresses, while other regions face the same fate in a few months. The need for a larger address space was predicted years ago and the next generation addressing scheme was devised as part of the development of Internet Protocol Version 6 (IPv6). Countries such as China and India had few IPv4 addresses and they have been forced to transition to IPv6 rather quickly. Today a significant number of the users in these countries are unable to communicate over IPv4 networks. The purpose of this thesis project is to discuss the transition to IPv6 and the transition to this new addressing scheme. IPv6 provides a much larger address space, along with a number of additional improvements in comparison to the previous version of IP (i.e., IPv4). Despite the advantages of adopting IPv6, the incentive to transition is low amongst well established businesses, especially those in regions that received a considerable number of IPv4 addresses initially. Instead different techniques have been employed in these places to mitigate the problem of IPv4 address exhaustion. It is also probable that this reluctance is a way to keep competing businesses out of the market for a while longer. This thesis aims to facilitate the transition from IPv4 to IPv6. / Miljontals användare är idag sammankopplade genom kommunikationskanaler som tillåter utbyte av information. Datornätet Internet utgörs av dessa användare och de enheter som sammanbinder dem. Internet är ett nätverk av nätverk med en myriad av olika datorutrustning såsom; spelkonsoler, smartphones, bärbara datorer, stationära datorer, handdatorer, även IPTV, kylskåp, tvättmaskiner, osv. Detta nätverk blomstrar på grund av noggrann planering och underhåll av internetleverantörer, nätoperatörer och andra. En ytterligare faktor som gör det möjligt för Internet att fungera är de fyra logiska skikt av abstaktion i TCP/IP-protokollstacken, en standard för datakommunikation. Ett av dessa skikt ansvarar för överföring av datapaket från en ändpunkt till en annan. Detta skikt är kallad Internet Protocol(IP) layer. Ursprungligen ansågs en 32-bitars adress vara mer än tillräcklig. Dessa IP-adresser delades ut till olika regioner rätt så oproportionerligt till stor del beroende på antalet adresser en region begärt. Idag efter en rad uppfinningar inom området(såsom webben/world wide web) och en snabb tillväxt i antal enheter som önskar ansluta sig till Internet är det tillgängliga adressutrymmet i stort sett slut. Regioner med stor befolkning men med få tilldelade block av IP-addresser har börjat göra slut på sina tilldelade adresser medan andra regioner står inför samma öde inom några månader. Behovet av ett större adressrymd sågs flera år sedan och nästa generations addresseringsschema utformades som en del av utveckligen, Internet Protocol version 6(IPv6). Länder som Kina och Indien hade ett fåtal IPv4-adresser och de har varit tvungna att övergå till IPv6 ganska snabbt. Idag kan inte ett stort antal användare i dessa länder kommunicera över IPv4-nätverk. Syftet med detta examensarbete är att diskutera övergången till IPv6 samt övergången till detta nya adresseringsschema. IPv6 ger en mycket större adressrymd samt en rad ytterligare förbättringar i jämförelse med den tidigare versionen av IP(dvs IPv4). Trots fördelarna med att övergå till IPv6 är viljan låg bland väletablerade företag, särskilt i regioner som mottagit ett stort antal IPv4-adresser från början. Dessa regioner tillämpar istället olika tekniker för att bromsa utmattningen av IPv4-adresser. Det är också troligt att denna motvija är ett sätt att hålla konkurrerande företag från marknaden ett tag till. Detta examensarbete syftar till att underlätta övergången från IPv4 till IPv6.

Deployment failure analysis using machine learning

Alviste, Joosep Franz Moorits January 2020 (has links)
Manually diagnosing recurrent faults in software systems can be an inefficient use of time for engineers. Manual diagnosis of faults is commonly performed by inspecting system logs during the failure time. The DevOps engineers in Pipedrive, a SaaS business offering a sales CRM platform, have developed a simple regular-expression-based service for automatically classifying failed deployments. However, such a solution is not scalable, and a more sophisticated solution isrequired. In this thesis, log mining was used to automatically diagnose Pipedrive's failed deployments based on the deployment logs. Multiple log parsing and machine learning algorithms were compared based on the resulting log mining pipeline's F1 score. A proof of concept log mining pipeline was created that consisted of log parsing with the Drain algorithm, transforming the log files into event count vectors and finally training a random forest machine learning model to classify the deployment logs. The pipeline gave an F1 score of 0.75 when classifying testing data and a lower score of 0.65 when classifying the evaluation dataset.

Early Childhood Educator Experiences Building Relationships with Families in Military-Connected Schools

Brown, Yolanda Seabrooks 01 January 2016 (has links)
Early childhood educators working to establish and maintain productive parent-teacher relationships are essential to the success of school-community partnerships in military- connected schools. The purpose of this study was to seek understanding of what early childhood educators had experienced while working with military families. Epstein's model of school, family, and community partnerships provided the conceptual framework for this study. The questions that guided this case study were designed to explore how early childhood educators established and maintained relationships with military families. Data collection consisted of semi-structured interviews with 8 early childhood educators in military-connected schools. Inductive data analysis was used to code the data initially and then to determine these 5 themes: (a) educators used many methods to communicate with families; (b) parent involvement was influenced by educator communication, family life, and school culture; (c) deployments impacted student achievement; (d) strong community resources were deemed necessary; and (e) military children benefitted from having resilient educators. Participants believed timely training addressing the unique needs of military families would be advantageous. A 3-day professional development for early childhood educators was developed to incorporate the findings of this study. School districts implementing the professional development for early childhood educators in a strong school, family, and community partnership will result and will lead to positive social change by increasing the academic achievement, emotional wellbeing, and social welfare of children of military families attending military-connected schools.
