Dissertations / Theses on the topic 'Model federation'

L'ingénierie des systèmes complexes et systèmes de systèmes conduit souvent à des activités de modélisation (MA) complexes. Les problèmes soulevés par les MA sont notamment : comprendre le contexte dans lequel elles sont exécutées, comprendre l'impact sur les cycles de vie des modèles qu'elles produisent, et finalement trouver une approche pour les maîtriser. L'objectif principal de cette thèse est d'élaborer une approche formelle pour adresser ce problème. Dans cette thèse, après avoir étudié les travaux connexes en ingénierie système et plus spécifiquement ceux qui portent sur la co-ingénierie du système à faire (le produit) et du système pour faire (le projet), nous développons une méthodologie nommée MODEF pour traiter ce problème. MODEF consiste en: (1) Caractériser les MA comme un système et plus généralement une fédération de systèmes. (2) Construire de manière itérative une architecture de ce système via la modélisation du contenu conceptuel des modèles produits par MA et leur cycle de vie, les tâches réalisées au sein des MA et leurs effets sur ces cycles de vie. (3) Spécifier les attentes sur ces cycles de vie. (4) Analyser les modèles (des MA) par rapport à ces attentes (et éventuellement les contraintes sur les tâches) pour vérifier jusqu'à quel point elles sont atteignables via la synthèse des points (ou états) acceptables. D'un point de vue pratique, l'exploitation des résultats de l'analyse permet de contrôler le déroulement des tâches de modélisation à partir de la mise en évidence de leur impact sur les modèles qu'elles produisent. En effet, cette exploitation fournit des données pertinentes sur la façon dont les MA se déroulent et se dérouleraient de bout en bout. A partir de ces informations, il est possible de prendre des mesures préventives ou correctives. Nous illustrons cela à l'aide de deux cas d'étude (le fonctionnement d'un supermarché et la modélisation de la couverture fonctionnelle d'un système). D'un point de vue théorique, les sémantiques formelles des modèles des MA et le formalisme des attentes sont d'abord données. Ensuite, les algorithmes d'analyse et d'exploitation sont présentés. Cette approche est brièvement comparée avec des approches de vérification des modèles et de synthèse de systèmes. Enfin, deux facilitateurs de la mise en œuvre de MODEF sont présentés. Le premier est une implémentation modulaire des blocs de base de MODEF. Le second est une architecture fédérée (FA) des modèles visant à faciliter la réutilisation des modèles formels en pratique. La formalisation de FA est faite dans le cadre de la théorie des catégories. De ce fait, afin de construire un lien entre abstraction et implémentation, des structures de données et algorithmes de base sont proposés pour utiliser FA en pratique. Différentes perspectives sur les composantes de MODEF concluent ce travail
The engineering of complex systems and systems of systems often leads to complex modelling activities (MA). Some challenges exhibited by MA are: understanding the context where they are carried out and their impacts on the lifecycles of models they produce, and ultimately providing a support for mastering them. How to address these challenges with a formal approach is the central challenge of this thesis. In this thesis, after discussing the related works from systems engineering in general and the co-engineering of the system to be made (product) and the system for make (project) systems specifically, we position and develop a methodology named MODEF, that aims to master the operation of MA. MODEF consists in: (1) characterizing MA as a system (and more globally as a federation of systems) in its own right; (2) iteratively architecting this system through: the modelling of the conceptual content of the models produced by MA and their life cycles, the tasks carried out within MA and their effects on these life cycles; (3) specifying the expectations over these life cycles and; (4) analysing models (of MA) against expectations (and possibly tasks constraints) - to check how far expectations are achievable - via the synthesis of the acceptable behaviours. On a practical perspective, the exploitation of the results of the analysis allows figuring out what could happen with the modelling tasks and their impacts on the whole state of models they handle. We show on two case studies (the operation of a supermarket and the modelling of the functional coverage of a system) how this exploitation provides insightful data on how the system is end-to-end operated and how it can behave. Based on this information, it is possible to take some preventive or corrective actions on how the MA are carried out. On the foundational perspective, the formal semantics of three kinds of involved models and the expectations formalism are first discussed. Then the analysis and exploitation algorithms are presented. Finally this approach is roughly compared with model checking and systems synthesis approaches. Last but not least, two enablers whose first objectives are to ease the implementation of MODEF are presented. The first one is a modular implementation of MODEF's buildings blocks. The second one is a federated architecture (FA) of models which aims to ease working with formal models in practice. Despite the fact that FA is formalised within the abstract framework of category theory, an attempt to bridge the gap between abstraction and implementation is sketched via some basic data structures and base algorithms. Several perspectives related to the different components of MODEF conclude this work

One of the promises of High Level Architecture (HLA) is the reusability of simulation components. Although HLA supports reusability to some extent with mechanisms provided by Object Model Template (OMT), when the developer wants to use an existing federate application within another federation with a different Federation Object Model (FOM) problem arises. She usually has to modify the federate code and rebuilt it. There have been some attempts to solve this problem and they, in fact, accomplish this to some extent but usually they fall short of providing flexible but also a complete mapping mechanism. In this work, a model based approach that mainly focuses on Declaration, Object and Federation Management services is explored. The proposed approach makes use of Model Integrated Computing (MIC) and .NET 2.0 technologies by grouping federate transitioning activities into three well-defined phases, namely, modeling, automatic code generation and component generation. As a side product, a .NET 2.0 wrapper to Runtime Infrastructure (RTI) has been developed to help developers create IEEE 1516 compatible .NET 2.0 federates in a programming language independent way.

Construction is unquestionably one of the largest industry contributors to any national economy. However, the sector faces significant problems with long-term performance, productivity and competitiveness; it is also very diverse and fragmented. It is generally accepted that the industry worldwide does not have a coherent model of innovation development, is unwilling to innovate, does not invest in R&D sufficiently, and shows a conservative attitude towards mass inclusion of cutting-edge technology into construction processes. The Russian construction industry is no exception. The Russian construction industry development lags far behind the world in creating and disseminating building materials and technologies. To stay competitive, Russian domestic construction companies need to continue their innovative activities, in order to exploit existing technological opportunities, despite the difficult financial climate. A high level of innovation performance is extremely important for this industry growth and for the development of the Russian economy. Innovations include the use of new building materials, machinery, and engineering equipment that increase the quality of operations and customer satisfaction (e.g. energy-efficient, soundproofing materials). They also include new, efficient construction technologies and software for architectural and construction design that enable the achievement of higher productivity, and lower construction times such as Building Information Modelling and off-site fabrication. This PhD study was founded on the innovation system approach which stresses that construction innovation is not limited by the boundary of a single construction company, but by a sectoral innovation system. In other words, the innovation performance of the industry depends not only on how individual firms perform in isolation, but on how they interact with other system actors (i.e. governments and academia) and contribute to the development and diffusion of innovations from a dynamic perspective. The theoretical framework developed for the Russian construction innovation system has a strong focus on these links between the government, industry and academia. Thus, creating a favourable environment for construction innovation is heavily dependent on government and construction companies. Moreover, construction innovation is also conditional upon the collaborative readiness of construction companies and research institutions to integrate their knowledge and expertise to maximise industry innovativeness. The overarching goal of this research was to explore the dynamic complexities inherent in construction innovation through the formulation of a system dynamics (SD) simulation model that focuses on the challenging Russian Federation context. The SD model was the outcome of a purpose-built integrated participatory systems modelling (IPSM) approach. This comprehensive IPSM approach employed and integrated various data collection techniques, including, questionnaire surveys, face-to-face interviews, direct expert consultations, empirical structural analysis, and a series of stakeholder workshops. A robustly developed SD model can help to address the challenges of transforming Russia’s construction industry into a highly developed sector by providing an understanding of how government policies and supportive programs could encourage industrialists to innovate, promote research and transfer technology. Such actions would ultimately improve industry innovativeness. The SD model sought to also understand and encapsulate the innovation dynamics of two innovation development typologies, namely, imitators and innovators. Imitators represented construction firms that introduced and implemented technological innovations by adopting and/or adapting ideas from others, in terms of improved construction materials, techniques, construction methods, products and services. Innovators represented companies that implemented technological innovations as a result of collaborative R&D. Such companies are constantly involved in R&D and implement newly introduced (i.e. subjected to significant technological changes) construction materials, techniques, goods and services based on new technologies, or on the combination of new technologies with existing ones. Overall, findings indicated that the Russian construction industry’s unwillingness to implement innovative technological advancements is primarily caused by the inability of the government to build an institutional, regulatory and legislative framework that would encourage firms to innovate. Among the key factors which hinder innovation processes are: the absence of a system of economic incentives for industrialists and research institutions; weak investment activity of construction companies due to a lack of funds; excessive administrative barriers; inappropriate technical regulation along with outdated construction norms and codes; a serious lack of research support; weak R&D collaboration between industry and academia; and conservative procurement methods. The SD model provided empirical evidence that effective strategies are required to overcome the challenges of transforming Russia’s construction industry into one which is highly innovative. The following factors might generate successful adoption of ground-breaking processes and products in the Russian construction industry: government support; client demand for innovation; access to information and knowledge for construction companies; and R&D collaboration. Hence, the number of imitators and innovators is only likely to increase if there is sufficient support for increased collaboration within the innovation system. Moreover, there is a need to improve procurement practises that would lead to increasing demand for high-quality construction goods and services. The SD model was also utilised to derive an understanding of the Russian construction industry with regards to innovation development and diffusion within the context of four plausible transition scenarios (i.e. business as usual, market forces, conservative development and innovation power). Specifically, the transition scenarios were developed by considering the variation of two important but uncertain factors driving innovation in the construction sector, namely: (1) the conditions and level of government financial support; and (2) demand for innovation related to market expectations, largely dictated by traditional versus progressive procurement processes. Simulation results under alternative scenario settings revealed that industry transformation requires sustained and coordinated innovation diffusion strategies that engage all innovation stakeholders. One key finding was that the Russian construction industry shows preference for imitation-oriented innovation development. Even though construction innovation diffused more rapidly, and seeded more innovators than imitators for the innovation power transition scenario (whereby increasing government support was coupled with extensive reductions in barriers), it would still take time to develop a sufficient proportion of truly innovative companies. The market forces and state-led conservative development transition scenarios showed similar levels of innovation outcomes within the modelling horizon, but predominately yielded innovation imitators. Lastly, the extensive scenario analysis findings culminated in the formulation of both policy and practical recommendations for enhancing innovativeness in the Russian construction sector, for overcoming its excessive conservatism, and for shaping a successful industry transition into an innovative future. In summary, this PhD thesis has made significant contributions to the theoretical, methodological and practical knowledge in the fields of construction innovation and systems modelling. The application of a systems approach to the analysis of construction innovation processes provided insights into both the complexity and inherent dynamics of innovation processes caused by multiple feedback loops, non-linearity, and time delays in decision-making. The IPSM modelling approach provides both a high degree of scientific rigour and an efficient participatory modelling procedure for building SD models. It can be used to deal with various problems where uncertainty in scientific knowledge, and lack of empirical data presents difficulties. Finally, the herein demonstrated concept of connecting a particular SD model for a particular system (i.e. construction innovation in this study) with that of macro industry transition scenarios, would be useful for government policy-makers to develop more fit-for-purpose strategies.

Advances in computer communications technology, the recognition of common areas of functionality in related systems, and an increased awareness of how enhanced information access can lead to improved capability, are driving an interest toward integration of current stand-alone systems to meet future system requirements. However, differences in hardware platforms, software architectures, operating systems, host languages, and data representation have resulted in scores of stand-alone systems that are unable to interoperate properly. Youngαs Object Oriented Model for Interoperability (OOMI) defines an architecture and suite of software tools for resolving data representational differences between systems in order to achieve the desired system interoperability. The Federation Interoperability Object Model (FIOM) Integrated Development Environment (IDE) detailed in this thesis is a toolset that provides computer aid to the task of creating and managing an interoperable federation of systems. This thesis describes the vision and requirements for this tool along with an initial prototype demonstrating how emerging technologies such as XML and Data Binding are utilized to capture the necessary information required to resolve data representational differences between systems. The material presented in this thesis has the potential to significantly reduce the cost and effort required for achieving interoperability between DoD systems.

New course of geometry for differentiated teaching is introduced.

Military simulation and command and control federations have become large, complex distributed systems that integrate with a variety of legacy and current simulations, and real command and control systems locally as well as globally. As these systems continue to become increasingly more complex so does the data that initializes them. This increased complexity has introduced a major problem in data initialization coordination which has been handled by many organizations in various ways. Service-oriented architecture (SOA) solutions have been introduced to promote easier data interoperability through the use of standards-based reusable services and common infrastructure. However, current SOA-based solutions do not incorporate formal governance techniques to drive the architecture in providing reliable, consistent, and timely information exchange. This dissertation identifies the need to establish governance for common data initialization service development oversight, presents current research and applicable solutions that address some aspects of SOA-based federation data service governance, and proposes a governance reference model for development of SOA-based common data initialization services in military simulation and command and control federations.

Proponents of CB claim that the system can provide an effective and efficient framework for a large scale national ABE programme which articulates with national education and vocational training systems. This framework provides a particular kind of answer to the 'literacy for what' question. The emphasis is on development. In this research, this view is contrasted with a version of literacy which gives a different answer to the 'literacy for what' question. Researchers such as Street and Wagner and many of the Non-government organisations affiliated to the National Literacy Co-operative prefer to view literacy as a free standing programme concentrating on individual and local needs. These contrasting positions will be used to consider the relative strengths and weaknesses of CB for ABE. While the possibility of using a CB system for the ABE programme in the building industry will be considered, the research will also consider the opportunity of CB beyond the specific needs of the building industry.

This thesis puts forth a process for ontology driven distributed simulation through a case study. Ontology is regarded as a domain model, including objects, attributes, methods and object relations. The case study involves trajectory simulation. A trajectory simulation is a piece of software that calculates the flight path and other parameters of a munition, such as its orientation and angular rates, from launch to impact. Formal specification of trajectory simulation domain is available as a domain model in the form of an ontology, called Trajectory Simulation ONTology (TSONT). Ontology driven federation development process proposed in this thesis is executed in three steps. The first step is to analyze the TSONT and to create instances of individuals guided by the requirements of the targeted simulation application, called Puma Trajectory Simulation. Puma is the simulation of a ficticious air-to-ground guided bomb. The second step is to create the High Level Architecture(HLA) Federation Object Model (FOM) using Puma Simulation individuals. FOM will include the required object and interaction definitions to enable information exchange among federation members, including the Puma federate and the Exercise Manager federate. Transformation from the ontology to FOM is realized in two ways: manually, and by using a tool called OWL2OMT. The third step is to implement the Trajectory Simulation federation based on the constructed FOM. Thus, the applicability of developing HLA federates and the federation under the guidance of ontology is demonstrated.

MCC (Mobile Cloud Computing) est un candidat très fort pour le NGN (Next Generation Network) qui permet aux utilisateurs mobiles d’avoir une mobilité étendue, une continuité de service et des performances supérieures. Les utilisateurs peuvent s’attendre à exécuter leurs travaux plus rapidement, avec une faible consommation de batterie et à des prix abordables ; mais ce n’est pas toujours le cas. Diverses applications mobiles ont été développées pour tirer parti de cette nouvelle technologie, mais chacune de ces applications possède ses propres exigences. Plusieurs MCA (Mobile Cloud Architectures) ont été proposées, mais aucune n'a été adaptée pour toutes les applications mobiles, ce qui a mené à une faible satisfaction du client. De plus, l'absence d'un modèle d'affaires (business model) valide pour motiver les investisseurs a empêché son déploiement à l'échelle de production. Cette thèse propose une nouvelle architecture de MCA (Mobile Cloud Architecture) qui positionne l'opérateur de téléphonie mobile au cœur de cette technologie avec un modèle d'affaires de recettes. Cette architecture, nommée OCMCA (Operator Centric Mobile Cloud Architecture), relie l'utilisateur d’un côté et le fournisseur de services Cloud (CSP) de l'autre côté, et héberge un cloud dans son réseau. La connexion OCMCA / utilisateur peut utiliser les canaux multiplex menant à un service beaucoup moins cher pour les utilisateurs, mais avec plus de revenus, et de réduire les embouteillages et les taux de rejet pour l'opérateur. La connexion OCMCA / CSP est basée sur la fédération, ainsi un utilisateur qui a été enregistré avec n’importe quel CSP, peut demander que son environnement soit déchargé de cloud hébergé par l'opérateur de téléphonie mobile afin de recevoir tous les services et les avantages de OCMCA.Les contributions de cette thèse sont multiples. Premièrement, nous proposons OCMCA et nous prouvons qu'il a un rendement supérieur à toutes les autres MCA (Mobile Cloud Architectures). Le modèle d'affaires (business model) de cette architecture se concentre sur la liberté de l'abonnement de l'utilisateur, l'utilisateur peut ainsi être abonné à un fournisseur de cloud et être toujours en mesure de se connecter via cette architecture à son environnement à l'aide du déchargement et de la fédération
Mobile cloud computing is a very strong candidate for the title "Next Generation Network" which empowers mobile users with extended mobility, service continuity and superior performance. Users can expect to execute their jobs faster, with lower battery consumption and affordable prices; however this is not always the case. Various mobile applications have been developed to take advantage of this new technology, but each application has its own requirements. Several mobile cloud architectures have been proposed but none was suitable for all mobile applications which resulted in lower customer satisfaction. In addition to that, the absence of a valid business model to motivate investors hindered its deployment on production scale. This dissertation proposes a new mobile cloud architecture which positions the mobile operator at the core of this technology equipped with a revenue-making business model. This architecture, named OCMCA (Operator Centric Mobile Cloud Architecture), connects the user from one side and the Cloud Service Provider (CSP) from the other and hosts a cloud within its network. The OCMCA/user connection can utilize multicast channels leading to a much cheaper service for the users and more revenues, lower congestion and rejection rates for the operator. The OCMCA/CSP connection is based on federation, thus a user who has been registered with any CSP, can request her environment to be offloaded to the mobile operator's hosted cloud in order to receive all OCMCA's services and benefits

The main objective of the doctorate thesis was to explore the causes of the current state of relations between the EU and Russia and to provide substantiation for future effective cooperation. The main analytical assumption of the thesis is that deeper regional economic cooperation creates positive effects for improvement of economic relations. Based on that assumption a complex exploratory framework with solid theoretical grounding was created in order to evaluate potential gains from trade liberalization scenarios between the EU and Russia. Main research is focused on the three following areas: historical background of economic relations, current developments and perspectives of the future cooperation in light of trade liberalization. Historical background of common economic relations stems from political and economic development on both sides, legal and institutional framework and problematic areas. Current development of trade and economic relations is based on analysis of trade flows in goods, trade in services and capital flows. Analysis of the future development is based on three liberalization scenarios: - Accession of Russia to the World Trade Organization (WTO), - Free trade agreement (FTA) -- scrapping customs tariffs between the EU and Russia, - Comprehensive free trade agreement (FTA+) -- reduction of non-tariff barriers to trade, liberalization of trade in services and capital flows, regulatory harmonization. Meta-analysis of different computable general equilibrium (CGE) modeling is used to evaluate the liberalization scenarios. Research results proved positive effects of trade liberalization for both sides. However, comprehensive free trade agreement seems to be the most effective form of trade liberalization with maximum economic welfare gains for the EU and the Russian Federation.

Plurale Weltinterpretationen praktizieren wir täglich, meist ohne uns darüber bewusst zu sein. Zustande kommen sie durch die gleichzeitige und gleichwertige Existenz verschiedener Modelle der Weltinterpretation. Sie sind Produkte menschlicher Schöpferkraft und stehen als parallele Realitäten einander ergänzend und einander widersprechend nebeneinander. Das Buch führt am Beispiel der Tyva Südsibiriens in zwei Modelle der Weltinterpretation und in die Praxis des Umgangs mit ihnen ein. Es zeigt, wie einzelne lokale Akteure zwei von mehreren Modellen flexibel zum Einsatz bringen, um Situationen zu deuten und in ihnen zu handeln. Es wird deutlich, welchen Regeln die Tyva dabei folgen, welche Gründe sie leiten und welche Folgen sie zu tragen haben. Das Ergebnis ist ein Bild zeitgenössischer Kultur, das der gegenwärtig gegebenen Flexibilität und Pluralität des menschlichen Deutens, Handelns und Verhaltens gerecht wird
Plural World Interpretations are part of our everyday lives, even if we are not aware of the fact. They result from the simultaneous existence of different but equal models for interpreting the world we live in. These models are the product of human constructivity and co-exist as parallel realities, complementing and contradicting each other. Based on fieldwork among the Tyva of southern Siberia, the book discusses the practice of dealing with this multiplicity of world interpretations and shows how individual actors oscillate flexibly between two of many possible models for interpreting specific situations and act on them. The rules Tyvans apply in varying contexts, the reasons behind their choices and the consequences they have to deal with, are analysed. The result is an account of contemporary culture that explores the flexibility and plurality of human interpretation, action and behaviour

Pesquisa de mestrado que procura integrar duas linhas de estudo sobre políticas públicas, uma que aborda o fenômeno da participação social e outra que analisa a influência dos arranjos federativos no seu desenvolvimento, e a partir delas responder à indagação se o modelo de relações intergovernamentais previsto na constituição brasileira de 1988 favorece ou inibe a participação da sociedade na implementação e execução das políticas públicas. Trabalhos anteriores apontam que se a participação social é responsável por melhorar a qualidade das decisões governamentais e por torná-las mais fáceis de serem implementadas, sendo natural que se busquem arranjos que estimulem a participação e removam os entraves normalmente observados à sua efetividade. Este estudo discute a afirmação de que políticas desenvolvidas em estados federativos, por serem descentralizadas, seriam mais abertas à participação, o que considera quase exclusivamente à proximidade geográfica entre sociedade e governo como fator decisivo para o envolvimento social. Em sentido oposto, o estudo do marco normativo de desenvolvimento das políticas públicas no Brasil aponta diferentes padrões de relacionamento entre níveis de governo para o exercício de competências legislativas, administrativas e financeiras, compatíveis com cenários descritos pela literatura como propensos a afetar o grau de interesse da sociedade na participação. São estudados sistemas de Gerenciamento de Recursos Hídricos e de Unidades de Conservação, casos da Bacia do Alto Tietê e APAs Bororé-Colônia e Capivari-Monos utilizando a variável quantitativa de frequência dos representantes nas reuniões e qualitativamente analisa o conteúdo das manifestações da sociedade civil registradas nas atas daquelas reuniões em busca de padrões de discurso e decisão que confirmem ou refutem a hipótese de que a complexidade do arranjo federativo opera como um inibidor da participação social na implementação e execução das políticas públicas no Brasil.
Masters study that aims to integrate two lines of research on public policy, one that addresses the phenomenon of social participation and another that analyzes the influence of the federal arrangements in its development, and from them to answer the question whether the model of intergovernmental relations laid down in the brazilian Constitution of 1988 favours or inhibits the participation of society in the implementation and execution of public policies. Previous works show that social participation is responsible for improving the quality of government decisions and make them easier to be implemented, being natural to seek arrangements to stimulate it and remove obstacles usually observed to its effectiveness. This study discusses the assertion that policies developed in federal states, because they are decentralized, would be more open to participation, which takes in account almost exclusively the geographic proximity between society and Government as a decisive factor for social involvement. The study of normative landmark public policy development in Brazil points out different patterns of relationship between levels of government regarding legislative, administrative and financial skills consistent with scenarios described in literature as likely to affect the degree of interest of the society in participation. A case study is conducted on water resources and protection areas management policies, the Alto Tietê basin cases and APAs Bororé-Colônia and Capivari-Monos, using as quantitative variable the frequency of representatives in meetings and qualitative analysis on the content of civil society manifestations recorded in the minutes of those meetings searching for patterns of speech and decision to confirm or refute the hypothesis that the complexity of the federal arrangement operates as an inhibitor of social participation in the implementation and execution of public policies in Brazil.

La criticité croissante des systèmes industriels les expose davantage aux menaces du monde cyber. En particulier les menaces persistantes avancées ou Advanced Persistent Threats (APT) sont des attaquants sophistiqués dotés de ressources conséquentes et ciblant spécifiquement les systèmes critiques. Les méthodologies de cyber-défense actuelles permettent de protéger les systèmes contre les cyber-menaces classiques mais elles peinent à contrer efficacement les APT. En effet, les APT usent de stratégies complexes et de tactiques de dissimulation qui les rendent difficile à contrecarrer. Pour répondre à ce besoin, la méthodologie d’Operational Design tirée des stratégies militaires permet de mieux comprendre l’établissement de stratégie de ces attaquants sophistiqués. Cette méthodologie axée sur la mission et adaptée au contexte des APT repose sur la fédération de plusieurs processus de spécification, de modélisation et d’analyse pour produire une stratégie opérationnelle. Pour évaluer cette approche, un outillage fédéré complet a été conçu et appliqué à un cas d’étude d’une mission d’attaque de système de pompage d’eau
Critical industrial systems are prime targets of cyber threats. In particular the Advanced Persistent Threats (APT) are sophisticated and well-resourced attacks targeting valuable assets. For APTs both the attack and the defense require advanced planning and strategies similar to military operations. The existing cyber-security-aware methodologies achieve valuable results for regular cyberthreats, however they fail to adequately address APTs due to their refined strategies and evasive tactics. The Operational Design methodology of military forces helps in better understanding how APTs devise their strategies. This mission-driven methodology adapted to the APT context relies on the federationof several processes of specification, modeling and analysis in order to produce an operational strategy. To evaluate this approach, a complete federation framework has been developed and applied to the case study of a mission of attack on a water pumping station

В настоящее время существует определенная модель организации информационного взаимодействия органов казначейства, налоговых, таможенных органов, банков, распорядителей и получателей бюджетных средств, т.е. всех субъектов бюджетного и налогового процессов.

Les infrastructures informatiques font partie de notre vie quotidienne et ont gagné ces dernières décennies une importance capitale. Au cœur de notre système bancaire, de nos transports et de nos hôpitaux, leur omniprésence et les implications liées à leur défaillance en font une cible privilégiée pour les attaquants. Au-delà du risque de sécurité, ces infrastructures sont soumises à un ensemble de risques de sûreté, allant de l’aléa climatique à l’incendie industriel, en passant par la simple usure des composants mécaniques. Ces risques, bien que prévisibles, ne sont pas toujours pris en compte par les entreprises et peuvent mener à des conséquences parfois catastrophiques. Nos travaux se positionnent tout au long du processus de gestion des risques. Nous défendons la thèse qu’une modélisation correcte et exhaustive des infrastructures informatiques permet de déduire un ensemble de propriétés de sûreté et de sécurité constituant une analyse des risques satisfaisante du système d’information étudié. Nous proposons un ensemble de recommandations et de méthodes pour procéder collaborativement à la modélisation des infrastructures et à l’étude du risque. Enfin, nous présentons un langage de description d’infrastructures formellement spécifié, CL/I, faisant le lien entre modèles d’infrastructures, outils de vérification formelle et supervision fonctionnelle
IT infrastructures are part and parcel of our daily lives, and have become of vital importance over the last few decades. At the heart of our banking system, transport facilities and hospitals, their omnipresence and the implications of their failure make them a prime target for attackers. Beyond the security risk, these infrastructures are subject to a whole range of safety risks, from climatic events to industrial fires, to the sheer wear and tear of mechanical components. These risks, although foreseeable, are not always taken into account by companies, and can lead to potentially catastrophic consequences. Our work encompasses the entire risk management process. We defend the thesis that correct and exhaustive modeling of infrastructures allows the deduction of a set of safety and security properties constituting a satisfying risk analysis of the information system under study. We propose a set of recommendations and methods to collaboratively conduct infrastructure modeling and risk analysis. Finally, we present a formally specified infrastructure description language, CL/I, linking infrastructure models, formal verification and functional supervision

Esta tese trata do modelo federativo brasileiro a partir do aparato teórico proporcionado pela abordagem do modelo agente-principal. A aplicação do modelo do agente principal e outros elementos da teoria da informação buscam identificar problemas de coordenação e assimetria de informações na formulação das políticas públicas em especial da política pública do ensino fundamental e médio. Neste sentido o arranjo federativo atual é elemento que impede a máxima eficiência das políticas, pois tal arranjo, não proporciona com base na argumentação do modelo do agente-principal, a perfeita definição de papeis e responsabilidades dos entes federativos. _______________________________________________________________________________ ABSTRACT
This theory treats of the Brazilian federal model starting from the proportionate theoretical apparatus for the approach of the agent-principal model. The application of the principalagent model and other elements of the theory of the information look for to identify coordination problems and asymmetry of information especially in the formulation of the public politics of the public policies of the fundamental and medium teaching. In this sense the current federal arrangement is element that impedes the maxim efficiency of the politics, because such arrangement, doesn't provide with base in the argument of the agentprincipal model, the adequate definition of you eat and responsibilities of the federal beings.

The 1995 Rugby World Cup and more recently the 2010 FIFA Football World Cup proved that sport can unite a previously divided nation. In order to participate in these major tournaments and events on an international level, national sports teams have to be competitive. The funding models used by national sports federations play a vital role in ensuring that national sports teams are competitive. The aim of this study was to explore the relationship between the funding models used by the South African Sports Confederation and Olympic Committee and the National Sports Federations; and the performance at international competitions and events. The main research methodology adopted for this study was exploratory in nature. The research design utilised was a mixed-method approach with a longitudinal design and entailed the collection and analysis of data for the period 2001 to 2014. The results from the quantitative research did not reveal any clear relationship between the variables under consideration and the performance of the national sports federations. Additional information was gathered through semi-structured interviews, which proved to be invaluable in explaining why the quantitative research did not reveal any clear relationship, between the variables under consideration and the performance of the national sports federations.

O presente trabalho avalia a renúncia tributária dos entes federativos e os benefícios socioeconômicos gerados pelo modelo da Zona Franca de Manaus (ZFM). Nosso objetivo foi mensurar os custos sociais do modelo por intermédio da desoneração tributária ou gastos tributários dos Entes e confrontá-los com os benefícios locais que foram medidos pelos diversos indicadores socioeconômicos. A plataforma teórica tem como sustentáculo a teoria dos pólos de Desenvolvimento e a Teoria da Base Exportadora. Diversos aspectos da ZFM foram abordados, notadamente: a legislação pertinente, os principais incentivos envolvidos, o histórico, as atualidades, os resultados alcançados, as origens dos principais insumos, as principais dificuldades e as perspectivas do modelo. Além disso, foi dado ênfase na arrecadação dos Entes, principalmente na arrecadação tributária da Receita Federal no Amazonas e na arrecadação tributária do Estado do Amazonas; e a desoneração tributária do Governo Federal. No âmbito da arrecadação, foi comprovada que a arrecadação Federal no Estado é expressiva, aproximadamente 64% de toda arrecadação da segunda região fiscal da Receita Federal; no tocante à receita tributária Estadual, mostrou-se que vem aumentando nos últimos anos e que, em 2009, alcançou cifras de R$ 4,6 bilhões, sendo que a maior parte desta tem origem no ICMS. A arrecadação proveniente do PIM é expressiva uma vez que a arrecadação da indústria corresponde, aproximadamente, a 50%. Além disso, dos 10 maiores arrecadadores do tributo cinco são empresas que pertencem ao PIM. No que concerne ao gasto tributário, cujo estudo foi concentrado nos gastos federais, constatou-se que as desonerações previstas para a Região Norte são relevantes, mas estão distantes das apresentadas por outras regiões, principalmente as das regiões Sul e Sudeste (62,30% do total). Em relação aos gastos tributários com a ZFM, contatou-se que: R$ 3,3 bilhões correspondem a 16,3% do total da função industria; e na função orçamentária comércio e serviços R$ 8,8 bilhões correspondem a 27,7% do total. A criação da ZFM proporcionou pontos positivos (6° PIB do Brasil) e negativos (concentração de 80% do PIB do Estado) para Manaus. O PIB do Amazonas acompanhou o crescimento do PIB brasileiro e foi muito superior ao PIB da Região Norte. Entretanto, se fizermos uma análise tomando como base o ano de 2003, notaremos que o PIBpm per capita amazonense cresceu 61% em 2007, superior ao da Região (58%) e do Brasil (52%). Os resultados finais da pesquisa chegam à conclusão que as desonerações tributárias são expressivas, mas distantes de outras existentes em outras regiões do País e que, apesar das isenções fiscais, a arrecadação tributária no Estado é elevada. Sendo assim, os indicadores nos mostram que os custos sociais para manter os incentivos fiscais são menores do que os benefícios socioeconômicos usufruídos pelo Estado do Amazonas em decorrência da existência do PIM.
This thesis assesses the government´s tax resigns and the socioeconomics benefits created to Manaus Free Trade Zone (ZFM). Our objetive was measure the social cost of model ZFM have represented for public’s entities tax bills and to compare it with local benefits to established several socioeconomics indicators.The revision of literature focused on the theory of growth in industrial poles and export base theory. Were addressed various aspects of the ZFM, mainly: the legislation, the main incentives, the historical, current affairs, the achievements, the main difficulties and prospects of the model. Moreover, we focus on the collection of entities, especially, the tax collection of federal revenue in the amazon’s state and tax collection in the state of amazon; and the government´s tax resigns. As part of the collection, we proved that the collection is a significant Federal-state, approximately 64% the entire collection of the second fiscal region. regarding the state tax revenue, we show that has increased in recent years and in 2009 reached figures of R$ 4.6 billion, with most of this stems from the ICMS (Value Added Tax on Sale and Services). The collection proceeds from the PIM (industrial pole of Manaus) is significant since the collection of the industry corresponds to approximately 50%. In addition, the 10 biggest taxpayers are 05 companies that belong to the PIM. Regarding the expenditure tax, whose study focused on federal spending, we proved that the tariff reductions or tax resigns planned for the northern region are significant, but are far from those given by other regions, mainly in South and Southeast (62.30% of total ). Regarding tax bills with the ZFM, contact: R$ 3.3 billion, representing 16.3% of the total light industry, and commerce and in the civil service budget R$ 8.8 billion, representing 27.7% of total.The creation of the ZFM gave positive points (6º of GDP in Brazil) and negative (concentration of 80% of State GDP) to Manaus. The Amazon’s GDP has followed growth of Brazil's GDP and GDP was much higher than the Northern Region. However, making an analysis based on year 2003, we note that GDP pm "per capita" Amazon grew 61% in 2007, higher than the Region (58%) and Brazil (52%). The final survey results come to the conclusion that the tax bills are significant, but far from existing in other regions of the country and that despite the tax exemptions, tax collections in the state is high. Thus, the indicators show us that the social costs to keep tax incentives that are lower socio-economic benefits enjoyed by the city of Manaus, since there's PIM.

Four themes emerge from the study that is presented in favor of the idea of a associational unionism: the action, on the global ground, of multinational companies; the response of international trade unionism, by its most eloquent actors, towards capital; the ways in which workers can, from the workplace, organize themselves to participate in the governance of the company; and the interrelationship that labour, from the workplace to the international scene, may need to keep to their survival, in an complex environment of collective labour relations, with other types of collective representations of workers, from a non-union nature, assembled by singular means (personnel delegates or elected representatives of workers) or by collective means (committees or commissions of company or factory). The debate about the connections between supposed distant themes provide the material source from which the unions can expect to face the advance of capital, while they can build, from the workplace to the global field, democratic environments for more respectful and equal coexistence between labour and capital. One of the instruments, the study presents, for the union movement, particularly in Brazil, is the idea of a associational unionism, whereby unions, in a vertical orientation, link themselves, with information and experience traffic, by holding minimum rights regarding employee participation in the governance of the company, with various levels through which workers organize from the workplace to the international stage; and, in a horizontal orientation, link themselves, with information and experience traffic through the exploitation of rights of participation in the governance of the company, with collective representations of workers of a non-union nature, from the workplace to the international scene. So far the approach of all those interrelationships is not usual for the industrial relations Law in Brazil, although present though sometimes not so quiet or in a simple manner for the union movement in European countries and to countries seen as the "North", part of the bibliographic references eminently come from European and American perspectives, but not at any time losing the horizon of the political and legal Brazilian scene, as to propose, even in the context of the restrictive Brazilian union model, or beyond that model, new ways for the unionism act and think
Quatro temas afloram do estudo que se apresenta em prol da ideia de um sindicalismo associativo: a atuação, no terreno global, das empresas multinacionais; a resposta do sindicalismo internacional, mediante seus atores mais eloquentes, ao avanço do capital; as formas mediante as quais os trabalhadores podem, desde o local de trabalho, se organizar para participar do governo da empresa; e a inter-relação que o sindicalismo, desde o local de trabalho até o cenário internacional, pode e necessita manter, para a sua sobrevivência, em um ambiente de complexas relações coletivas de trabalho, com outros tipos de representações coletivas de trabalhadores, de perfil unitário e não-sindical, montadas por vias singulares (delegados de pessoal ou representantes eleitos de trabalhadores) ou por vias coletivas (comitês ou comissões de empresa ou de fábrica). O debate em torno das conexões existentes entre supostamente tão distantes temas oferece a fonte material a partir da qual o sindicalismo pode se preparar para enfrentar o avanço do capital, ao mesmo tempo em que pode construir, desde os locais de trabalho até o terreno global, ambientes mais democráticos para a convivência, com maior respeito e equivalência, entre trabalho e capital. Um dos instrumentos que, do estudo, se apresenta para o movimento sindical, particularmente ao brasileiro, é a ideia de um sindicalismo associativo, mediante a qual os sindicatos, em uma orientação vertical, podem estabelecer relações, com tráfego de informações e de experiências, pela exploração de mínimos direitos atinentes à participação dos trabalhadores no governo da empresa, com os diversos níveis por meio dos quais os trabalhadores se organizam desde os locais de trabalho até o cenário internacional; e, em uma orientação horizontal, podem estabelecer relações, com tráfego de informações e de experiências, mediante exploração de direitos de participação no governo da empresa, com representações coletivas de trabalhadores de natureza unitária e não-sindical, desde os locais de trabalho até o cenário internacional. Em razão de a abordagem de todas essas inter-relações não ser usual para o Direito Coletivo do Trabalho no Brasil, embora presente ainda que, por vezes, não tão tranquila para o movimento sindical de países europeus e para os países tidos como do Norte , a pesquisa bibliográfica parte de referências eminentemente europeias e norte-americanas, mas sem, em nenhum momento, perder o horizonte do cenário político e jurídico brasileiro para propor, mesmo em contexto de unicidade, ou para além da unicidade, outra forma de agir e de pensar para o sindicalismo

Au cours de la première décennie du XXIe siècle l'Arctique a fait l’objet d’une attention croissante de la part des chercheurs, des politiciens et des multinationales. En effet, les problématiques liées au changement climatique, et le regain d’interêt politique et économique des Etats côtiers et non côtiers, a peu à peu fait apparaître cette région comme un endroit stratégique sur l'échiquier des grandes puissances. Depuis 2001, la Fédération de Russie a entrepris plusieurs actions afin de garantir ses intérêts nationaux dans ce qu'elle considère comme l’Arctique russe, un espace qui comprend environ 22600 kilomètres de littoral avec l'océan Arctique. Or, le changement climatique, les développements socio-économiques et les impératifs stratégiques ont conditionné cette politique pour l’Arctique. Les oblasts de Mourmansk et d’Arkhangelsk jouent, de nos jours, un rôle majeur dans la mise en œuvre de la stratégie russe pour la région arctique. Ce travail évaluera donc les défis majeurs de stratégie et de sécurité nationale russes en Arctique occidental au regard des récents changements du modèle politique et économique russe, du rôle émergent d'acteurs privés et étrangers ainsi que des spécificités des régions arctiques et sous-arctiques. Dans une première partie de notre travail nous essayerons de souligner l’importance stratégique et économique de l’Arctique Occidental pour la Fédération de Russie. Une approche historique nous permettra de mieux comprendre le rôle actuel des oblasts de Mourmansk et d’Arkhangelsk tandis que l’analyse de l’évolution démographique, industrielle et commerciale de ces régions nous fera apprécier son potentiel socio-économique. Enfin, une analyse de l’adaptation des industries énergétiques et du complexe militaro-industriel aux marchés internationaux sera entreprise ainsi qu’une évaluation des risques liés au changement climatique et à la pollution industrielle. Dans une deuxième partie, nous analyserons les principales problématiques rencontrés par les acteurs étatiques et privés en Arctique occidental. Afin d’identifier les principaux enjeux, nous avons transposé des théories des relations internationales à la géopolitique (Waltz, Keohane, Putnam). Tout particulièrement, nous utiliserons pour cette analyse les modèles conceptuels de Graham Allison et son approche sur les intérêts nationaux
During the first decade of the XXIth century, the Arctic has received growing attention from scholars, policymakers and multinational corporations. Climate change as well as renewed political and economical interests from coastal and non-coastal States had repositioned this region as a prospective theater in the Great powers chessboard. Since 2001, the Russian Federation has taken several international and domestic actions to guarantee its national interest in what it considers as the Russian Arctic, a space that comprises about 22 600 kilometers of national coastline with the Arctic Ocean. But climate change, historical socio-economic developments and strategic imperatives have conditioned this engagement.The Murmansk and Arkhangelsk oblasts plays nowadays a leading role in the implementation of a cross-domain Russian strategy for the Arctic region. This dissertation will then assess the central challenges of Russian National Security and Strategy in the Occidental Arctic taking in consideration recent changes in the Russian Federation political and economical model, the emerging role of private and foreign actors and the specificity of Arctic and sub-Arctic regions.The first part of this dissertation will try to underline the past/current strategic and economical relevance of the Occidental Arctic for the Russian Federation. A historical approach will allow us to better understand the current role of Murmansk and Arkhangelsk oblasts while we will appreciate its socio-economic potential thanks to the analysis of demographic, industrial and commercial developments of these regions. Finally, a study on defense and energy industries adaptation to international markets will be conducted as well as a regional risk-assessment concerning climate change and industrial pollution.In a second part, our main objective is to demonstrate the strategic and economical importance of the Murmansk and Arkhangelsk oblasts for the Russian Arctic policy. This will lead us to analyse core issues in the Occidental Arctic for state and industry actors. The methodology applied to identify the main trends in these issues is a combination of the French school of geopolitics with relevant theories of international relations (Waltz, Keohane, Putnam). Graham Allison’s conceptual models and his approach on national interests will be applied in the analysis

Le cloud computing a été considéré comme une option pour exécuter des applications de calcul haute performance. Bien que les plateformes traditionnelles de calcul haute performance telles que les grilles et les supercalculateurs offrent un environnement stable du point de vue des défaillances, des performances, et de la taille des ressources, le cloud computing offre des ressources à la demande, généralement avec des performances imprévisibles mais à des coûts financiers abordables. Pour surmonter les limites d’un cloud individuel, plusieurs clouds peuvent être combinés pour former une fédération de clouds, souvent avec des coûts supplémentaires légers pour les utilisateurs. Une fédération de clouds peut aider autant les fournisseurs que les utilisateurs à atteindre leurs objectifs tels la réduction du temps d’exécution, la minimisation des coûts, l’augmentation de la disponibilité, la réduction de la consommation d’énergie, pour ne citer que ceux-Là. Ainsi, la fédération de clouds peut être une solution élégante pour éviter le sur-Approvisionnement, réduisant ainsi les coûts d’exploitation en situation de charge moyenne, et en supprimant des ressources qui, autrement, resteraient inutilisées et gaspilleraient ainsi de énergie. Cependant, la fédération de clouds élargit la gamme des ressources disponibles. En conséquence, pour les utilisateurs, des compétences en cloud computing ou en administration système sont nécessaires, ainsi qu’un temps d’apprentissage considérable pour maîtrises les options disponibles. Dans ce contexte, certaines questions se posent: (a) Quelle ressource du cloud est appropriée pour une application donnée? (b) Comment les utilisateurs peuvent-Ils exécuter leurs applications HPC avec un rendement acceptable et des coûts financiers abordables, sans avoir à reconfigurer les applications pour répondre aux normes et contraintes du cloud ? (c) Comment les non-Spécialistes du cloud peuvent-Ils maximiser l’usage des caractéristiques du cloud, sans être liés au fournisseur du cloud ? et (d) Comment les fournisseurs de cloud peuvent-Ils exploiter la fédération pour réduire la consommation électrique, tout en étant en mesure de fournir un service garantissant les normes de qualité préétablies ? À partir de ces questions, la présente thèse propose une solution de consolidation d’applications pour la fédération de clouds qui garantit le respect des normes de qualité de service. On utilise un système multi-Agents pour négocier la migration des machines virtuelles entre les clouds. En nous basant sur la fédération de clouds, nous avons développé et évalué une approche pour exécuter une énorme application de bioinformatique à coût zéro. En outre, nous avons pu réduire le temps d’exécution de 22,55% par rapport à la meilleure exécution dans un cloud individuel. Cette thèse présente aussi une architecture de cloud baptisée « Excalibur » qui permet l’adaptation automatique des applications standards pour le cloud. Dans l’exécution d’une chaîne de traitements de la génomique, Excalibur a pu parfaitement mettre à l’échelle les applications sur jusqu’à 11 machines virtuelles, ce qui a réduit le temps d’exécution de 63% et le coût de 84% par rapport à la configuration de l’utilisateur. Enfin, cette thèse présente un processus d’ingénierie des lignes de produits (PLE) pour gérer la variabilité de l’infrastructure à la demande du cloud, et une architecture multi-Cloud autonome qui utilise ce processus pour configurer et faire face aux défaillances de manière indépendante. Le processus PLE utilise le modèle étendu de fonction avec des attributs pour décrire les ressources et les sélectionner en fonction des objectifs de l’utilisateur. Les expériences réalisées avec deux fournisseurs de cloud différents montrent qu’en utilisant le modèle proposé, les utilisateurs peuvent exécuter leurs applications dans un environnement de clouds fédérés, sans avoir besoin de connaître les variabilités et contraintes du cloud
Cloud computing has been seen as an option to execute high performance computing (HPC) applications. While traditional HPC platforms such as grid and supercomputers offer a stable environment in terms of failures, performance, and number of resources, cloud computing offers on-Demand resources generally with unpredictable performance at low financial cost. Furthermore, in cloud environment, failures are part of its normal operation. To overcome the limits of a single cloud, clouds can be combined, forming a cloud federation often with minimal additional costs for the users. A cloud federation can help both cloud providers and cloud users to achieve their goals such as to reduce the execution time, to achieve minimum cost, to increase availability, to reduce power consumption, among others. Hence, cloud federation can be an elegant solution to avoid over provisioning, thus reducing the operational costs in an average load situation, and removing resources that would otherwise remain idle and wasting power consumption, for instance. However, cloud federation increases the range of resources available for the users. As a result, cloud or system administration skills may be demanded from the users, as well as a considerable time to learn about the available options. In this context, some questions arise such as: (a) which cloud resource is appropriate for a given application? (b) how can the users execute their HPC applications with acceptable performance and financial costs, without needing to re-Engineer the applications to fit clouds' constraints? (c) how can non-Cloud specialists maximize the features of the clouds, without being tied to a cloud provider? and (d) how can the cloud providers use the federation to reduce power consumption of the clouds, while still being able to give service-Level agreement (SLA) guarantees to the users? Motivated by these questions, this thesis presents a SLA-Aware application consolidation solution for cloud federation. Using a multi-Agent system (MAS) to negotiate virtual machine (VM) migrations between the clouds, simulation results show that our approach could reduce up to 46% of the power consumption, while trying to meet performance requirements. Using the federation, we developed and evaluated an approach to execute a huge bioinformatics application at zero-Cost. Moreover, we could decrease the execution time in 22.55% over the best single cloud execution. In addition, this thesis presents a cloud architecture called Excalibur to auto-Scale cloud-Unaware application. Executing a genomics workflow, Excalibur could seamlessly scale the applications up to 11 virtual machines, reducing the execution time by 63% and the cost by 84% when compared to a user's configuration. Finally, this thesis presents a product line engineering (PLE) process to handle the variabilities of infrastructure-As-A-Service (IaaS) clouds, and an autonomic multi-Cloud architecture that uses this process to configure and to deal with failures autonomously. The PLE process uses extended feature model (EFM) with attributes to describe the resources and to select them based on users' objectives. Experiments realized with two different cloud providers show that using the proposed model, the users could execute their application in a cloud federation environment, without needing to know the variabilities and constraints of the clouds

In this thesis we propose an HLA distributed federation that it incorporates with wired and wireless network environment, and IEEE 1516 high level architecture (HLA) to support seamless data communication and facilitate the higher host interoperabilities. Nevertheless, we elaborate the IP-based mobility management with forwarding client mechanism and deploy federate agents to achieve a low-complicated but high-practical mobility management for a wide variety of mobile devices. As the conventional wireless LAN is concerned, it inherently suffers from on information suspension and intermittent message loss as long as a phenomenon known as handoff occurs. Accordingly, we devise two kinds of information compensation models (ICM), including the conservative backup starting point method and optimistic indexing scheme, to cope with information suspension problem. In particular, the ICM would not aggravate computing loads of the distributed servers and exhaust memory space in the period of client’s short-term disconnection phase. As a consequence, we can show that the proposed federation architecture supports efficient mobility management functionalities, seamless data communication, and low system resource consumption from the experimental results.

Fan economy has become a dominant trend in the media and entertainment industry in recent years. Fans have not only created enormous economic value for the entertainment industry, but they have also brought benefits to the associated industry chain. In the pop music industry, the enormous economic profits in physical albums, digital or streaming music, shows and performances, or peripheral merchandises are basically created by fans. In other words, fans are the main source of economic drive in the entertainment industry. Mastering fans practically means a boost in product value; therefore, how to solidify and expand the fan base has become an important topic in the fan economy. With the rise of the Chinese music market, there have been many fan clubs spontaneously organized by general fans. They usually cooperate with record labels to participate in artists’ itineraries, such as invited activities and autograph sessions. With the advancement of technology and the advent of the Internet era, record labels or agencies of a certain size will create an official website or at least an affiliated page to the company’s website for their artists. Whether it is an official fan club formed by the company or an unofficial one by fans, they tend to have an incomplete system, scale and norms. Fans do not know what to believe or whom to listen to, and it is difficult to achieve the best promotion under such circumstances. In the author’s opinions, no fan club, either official or official, has a well-established system. In recent years, there have been some fan clubs with a paid subscription service. For example, JJ Federation VIP fan club, the case in this study, has exclusive services and welfares to satisfy the fans’ needs. It has its own website and App, and the ownership is held by the artist himself, so that the fans can be provided with a more perfect system, scale and welfare. Being an artist agent for many years, the author found the performance of JJ Federation VIP fan club is prominent in the industry, and thus he hopes to learn from its successful experience by studying the business model of the fan club. The research results showed that the success factors of JJ Federation VIP fan club for having a steady growth can be summarized as follows: 1) The leader’s ideology and continuous pursuit of innovation; 2) Its fan-centered operation that gradually becomes a successful business model; 3) Different combinations of marketing merchandises and personalized marketing strategies; 4) The use of people-oriented technology and the integration of virtual and real application; 5) The up-to-date transformation and changes that keep the sustainable development of fans’ power and enthusiasm. In view of rare studies on artists’ fan clubs with a paid subscription service in the past, the author hopes that the research results of this study can provide as a model and also a reference for the industry when making relevant decisions in the future.

This thesis concentrates on the case of Russian economy and assessment of its dependence on oil. Russia is often cited as an example of country suffering from resource curse as its natural wealth forms significant share of country's exports and revenues. Thesis will first concentrate on factors determining current state of Russian economy. Presence of the symptoms of Dutch disease in the Russian economy will be studied using the Vector error correction model (VECM) applied on the real effective exchange rate of country (REER). Thesis will also contain an assessment of Russian institutional environment to check for other symptoms of resource curse theory. Analysis of latest federal budget will be used to evaluate the sustainability of Russian federal finances. The thesis is concluded by discussion of results and possible paths of future development of Russian economy.

This study is a historical analytical investigation and theological interpretation of Wesleyan Methodists' political teaching and practice in Zimbabwe from 1891 to 1980. In an attempt to come up with an informed interpretation of the political teaching and activities, the study traced Wesleyan Methodist political praxis John Wesley, the founder of Methodism and interpreted his teaching and practice from a third world perspective. That perspective was used as a basis for evaluating the contextualisation of his teaching by Wesleyan Methodists in Zimbabwe. The Zimbabwean Wesleyan Methodists' political teaching and practice during the colonial era were explored using four themes: politics of land, race relationships, Federation and war. Two hypothetical statements were tested in this study: Wesleyan Methodism outlines a framework for constructive participation in politics, and the Wesleyan Methodist Church in Zimbabwe provided and supported positions of political leadership in Zimbabwe. The objectives of this study are to: unveil successes and failures of Wesleyan Methodists in Zimbabwean political arena, expose the historical significance of Wesleyan Methodist influence in politics for Zimbabwean history and present a historical account of the Wesleyan Methodist Church in Zimbabwe. The methodology preferred in this study included oral history and a combination of the ecumenical and southern approaches to Church history. The study utilised archival and oral data as primary sources, the translation model of contextual theology, holistic framework for analysing history, the principle of the overriding right and the conflict transformation model as part of the methodology. Through the use of the translation model of contextual theology, the study revealed how John Wesley used principles from the Christian message and Church tradition in addressing his political context. The study exposed that John Wesley was obsessed with accountability to God and constituency, respect for every person, respect for political structures as well as authorities and relationships among people as fundamental pillars in political activities. He based these on his understanding of God's free grace, people's liberty to accept or reject that grace and the validity of popular religious expression. The study revealed that Wesleyan Methodists in Zimbabwe had a special relationship with the colonial government due to an invitation by Cecil John Rhodes for the church to participate in the Pioneer Column. The relationship determined how retrogressive or progressive ministers responded to government requirements and made demands on government until the country's independence in 1980. The study also exposed how retrogressive Wesleyan Methodists moved from acceptance and collaboration to acceptance and selective rejection of colonial policies and how both retrogressive and progressive ministers employed the concept of non-contestation of participation in armed conflict and throwing one’s lot on the expected side. It also showed how progressive ministers contributed to the political emancipation of Africans and the role played by the mission-educated elite in Zimbabwe. The study ended with pointing out that Zimbabwean Wesleyan Methodist political teaching and practice had very bright future prospects at the independence of the country in 1980.

The overall purpose of this research has been the building or the improve- ment of semantic models for the representation of data related to smart cities and smart industries, in such a way that it could also be possible to build context-rich, user-oriented, ecient and eective applications based on such data. In some more detail, one of the key purposes has been the modelling of structural and the functioning aspects of the urban mobility and the produc- tion of instances exploiting the Open Street Map, that once integrated with trac sensors data, it has lead to the building and displaying of real-time trac reconstructions at a city level. One second key purpose has been the modelling of the Internet of Things, that allows today to seamlessy and e- ciently identify sensing devices that are deployed in a given area or along a given path and that are of a given type, and also inspect real-time data that they produce, through a user-oriented Web application, namely the Service Map. A pragmatic approach to the modelling has been followed, always tak- ing into consideration the best practices of semantic modelling on one side for that a clean, comprehensive and understandable model could result, and the reality of the data at our hands and of the applicative requirements on the other side. As said, the identication of architectures and methods that could grant eciency and scalability in data access has also been a primary purpose of this research that has led to the denition and implementation of a federation of Service Maps, namely the Super Service Map. The archi- tecture is fully distributed: each Super Service Map has a local list of the actual Service Maps with relevant metadata, it exposes the same interface as actual Service Maps, it forwards requests and builds merged responses, also implementing security and caching mechanisms. As said, the identica- tion of technologies, tools, methods, for presenting the data in a user-friendly manner is also has been a relevant part of this research, and it has led among the other to the denition and implementation of a client-server architecture and a Web interface in the Snap4City platform for the building, manage- ment, and displaying of synoptic templates and instances thanks to which users can securely display and iteract with dierent types of data. In end, some eort has been made for the automatic classication of RDF datasets as for their structures and purposes, based on the computation of metrics through SPARQL queries and on the application of dimensionality reduc- tion and clustering techniques. A Web portal is available where directories, datasets, metrics, and computations can be inspected even at real-time.
