一帶一路倡議是中國第五代領導人的政策之一，應該被視為整體戰略的一部分。為了評估一帶一路倡議的實際目的與風險，研究中國地緣政治與社會經濟局勢、前幾代中國領導人的政策（如西部大開發）、現任第五代領導人的政策（如中國夢與四個全面）。雖然並非與其它相關的分析相互排斥，結論指出一帶一路與第五代領導人其它政策具有協同效應、同時面對相對的急迫性，是中國第五代領導人經濟改革、輸出國營企業生產能力過剩、減輕資產泡沫破裂風險的工具之一。 / The Belt and Road Initiative is one corner of the Chinese fifth-generation leadership’s policymaking under the Xi Jinping administration, and should be understood as part of a cohesive whole. This study assesses the BRI, its actual goals, and its risks when analyzed alongside China’s geostrategic and socioeconomic positions, similar policies from previous generations of Chinese leadership such as the Western Development Strategy, and existing concurrent policies from the fifth-generation Chinese leadership such as the Chinese Dream and the Four Comprehensives. While not mutually exclusive with other explanations proposed for the BRI, this study suggests that due to its synergy with existing policies and its exceptional urgency, the fifth-generation leadership primarily uses the BRI as one tool amongst many to accommodate its economic reform, to export the production overcapacity of state-owned enterprises, and to mitigate any risks of an asset bubble collapse.

Uncertainty in rainfall forecasts affects the level of quality and assurance for decisions made to manage water resource-based systems. However, eliminating uncertainty in a complete manner could be difficult, decision-makers thus are challenged to make decisions in the light of uncertainty. This study provides statistical models as an approach to cope with uncertainty, including: a) a statistical method relying on a Gaussian mixture (GM) model to assist in better characterize uncertainty in climate model projections and evaluate their performance in matching observations; b) a stochastic model that incorporates the El Niño–Southern Oscillation (ENSO) cycle to narrow uncertainty in seasonal rainfall forecasts; and c) a statistical approach to determine to what extent drought events forecasted using ENSO information could be utilized in the water resources decision-making process. This study also investigates the relationship between calibration and lead time on the ability to narrow the interannual uncertainty of forecasts and the associated usefulness for decision making. These objectives are demonstrated for the northwest region of Costa Rica as a case study of a developing country in Central America. This region of Costa Rica is under an increasing risk of future water shortages due to climate change, increased demand, and high variability in the bimodal cycle of seasonal rainfall. First, the GM model is shown to be a suitable approach to compare and characterize long-term projections of climate models. The GM representation of seasonal cycles is then employed to construct detailed comparison tests for climate models with respect to observed rainfall data. Three verification metrics demonstrate that an acceptable degree of predictability can be obtained by incorporating ENSO information in reducing error and interannual variability in the forecast of seasonal rainfall. The predictability of multicategory rainfall forecasts in the late portion of the wet season surpasses that in the early portion of the wet season. Later, the value of drought forecast information for coping with uncertainty in making decisions on water management is determined by quantifying the reduction in expected losses relative to a perfect forecast. Both the discrimination ability and the relative economic value of drought-event forecasts are improved by the proposed forecast method, especially after calibration. Positive relative economic value is found only for a range of scenarios of the cost-loss ratio, which indicates that the proposed forecast could be used for specific cases. Otherwise, taking actions (no-actions) is preferred as the cost-loss ratio approaches zero (one). Overall, the approach of incorporating ENSO information into seasonal rainfall forecasts would provide useful value to the decision-making process - in particular at lead times of one year ahead.

Cette recherche questionne les incidences du rattachement du secteur du cinéma au ministère des Affaires culturelles au moment de l'avènement de la Ve République. Elle s'efforce de décrire l'oscillation permanente de l'administration d'André Malraux en la matière, partagée entre le souci de répondre avec exigence aux enjeux liés à la qualité de la production cinématographique, le besoin d'accorder le cinéma à la mission de prestige national et la nécessité d'élaborer une politique consensuelle en mesure de satisfaire les diverses parties prenantes de l'action publique. Sans nul doute ce dernier aspect s'avère essentiel pour asseoir son autorité au regard de l'instabilité gouvernementale qui a perduré longuement avant 1959 mais également en raison des bouleversements économiques, techniques et professionnels provoqués par l'apparition de la Nouvelle Vague. Bien que le modèle d'intervention français soit pleinement reconnu à l'échelle européenne sur ces années, certaines de ses orientations sont pourtant critiquées au plan national par une partie de la critique et des jeunes réalisateurs appartenant aux Cahiers du cinéma. La diversité des longs métrages soutenus par le système des avances sur recettes ne concorde pas avec l'exclusivité de la novation esthétique telle qu'elle a pu exister au temps du jury de la prime à la qualité de 1956 à 1960. La sélection nationale envoyée au Festival de Cannes est également peu goûtée en ce sens. La crise de fréquentation des salles de cinéma, laquelle perdure sur toute la période, accentue davantage ces crispations. Forcé de soumettre aux autorités gouvernementales un projet de rationalisation de l'ensemble de la filière, le Centre national de la cinématographie est en passe de limiter les possibilités d'existence des producteurs les plus modestes. Alors qu'une profonde stabilisation est parvenue à inscrire durablement l'intervention de l'État dans le domaine du cinéma, André Malraux s'apprête pourtant, à l'aube de la deuxième moitié des années 1960, à faire face à une contestation sans précédent de son action. / This study examines the implications of the attachment of film industry to the Ministry of Culture at the beginning of the fifth French Republic. This thesis strives to describe permanents fluctuations of André Malraux's administration between the concern to answer with requirement to the challenges relating to the high quality of the cinematographic production, the need to match the cinema with reasons of national prestige and the necessity to develop a consensual policy able to satisfy miscellaneous stakeholders of the public action. There is no doubt that this last aspect turns out to be crucial for establishing his authority in relation to governmental instability which has continued before 1959 but also because of upheavals provoked by Nouvelle Vague appearance. Although the French intervention model is completely recognized on European scale on this years, some of its options are yet criticized on the national level by a part of critics and young directors close to the magazine Les Cahiers du cinéma. The diversity of full-length movies subsidized by De Gaulle's government doesn't tally with the exclusivity of aesthetic innovation as it existed between 1956 and 1960. The French selection sent at Festival of Cannes is also not much appreciated on this way. The crisis of attendance in the cinemas, which existed all over this period, emphasized more these tenseness. André Malraux is consequently confronted with unprecedented protest movement of his action at the dawn of the second half of the sixties.

This thesis covers the development of complex HIL simulator for the fifth car door. The beginning of the thesis is dedicated to theoretical research in the area of In-the-Loop testing. Practical part describes development of HIL simulator complemented by power electronics part. A simulation environment Matlab/Simulink was used for control design and analysis. Before the beginning of the work was measured signal part of control unit and specific signal sequences were identified. The control was applied on sbRIO device from National Instruments company with the implementation of a model on FPGA. Specific requirements for sensing speed and generation of communication signals lead to creation of unique hardware for application needs. The result of the thesis is complex HIL simulator with intuitive GUI and possibility of simulations a wide range of DC motors.

With advancements in the mobile network architecture, from the Fourth Generation to the Fifth Generation, a vast number of new use cases becomes available. Many use cases require cloud-based services, where a service is deployed close to the user. For a user to communicate with a service, it connects to the mobile network base station, Fifth Generation Core network and then to the service. When the user changes physical location, the mobile network and the service must apply mobility techniques. This is to prevent tromboned traffic and provide low latency between user and service. When a handover occurs, so that a user’s attachment point to the mobile network is changed from the one base station to another and the User Plane Function changes, the cloud-based service may have to seamlessly move from one cloud to another as well. In this thesis, a Service mobility framework is proposed and implemented, which enables service live migration between edge clouds and it provides simple RESTful APIs. The evaluation of the framework shows that the proposed implementation adds low delays to the total migration time and the service downtime is also shown to be low in the case of video streaming with no service interruption. / Med framsteg i det mobila nätverkets arkitektur, sett från den Fjärde Generationen till den Femte Generationen, så blir nya användningsområden tillgängliga. Bland de nya användningsområdena inkluderas molnbaserade tjänster, där tjänster är placerade nära användare, dessutom har vissa områden behov av dessa molnbaserade tjänster. För att en användare ska kunna kommunicera med en tjänst så måste den först ansluta till det mobila nätverkets basstationer och sedan till Femte Generationens kärnnätverk, för att sedan kunna kommunicera med tjänsten. När användaren förflyttar sig från en plats till en annan, så måste det mobila nätverket och tjänsten tillämpa rörlighetstekniker, som förflyttning av tjänsten. Förflyttningen är för att förhindra trombonerad trafik och att förse låg latens mellan användare och tjänst. När en överlämning sker, d.v.s att en användares kopplingspunkt till det mobila nätverket ändras, från en basstation till en annan, och att User Plane Function ändras, så kan även den molnbaserade tjänsten förflytta sig sömlöst från ett moln till ett annat. I denna avhandling presenteras ett tjänströrlighetsramverk som möjliggör tjänströrlighet mellan moln och erbjuder enkla RESTfulla API:er. Evaluering av ramverket visar att implementationen bidrar med låga fördröjningar till den totala migrations tiden samt att tjänster med videoströmming har lågt driftstopp utan tjänstavbrott.

Internet of Things, or the infrastructure of the information age society, is an expanding area of research. It is the idea that physical things that we have today, can be turned into devices by being connected to a network. The purpose of these devices is through more sensors and actuators, allow smarter and more robust infrastructure to be built, as well as improving consumer devices interoperability. This thesis will investigate the current state of the art application layer communication protocols that have been developed with resource constrained mobile devices in mind. It will look specifically at high latency mid-range wireless cellular communication by investigating how the protocols affect energy consumption for an embedded Internet of Things device. This is done with the constraint that these findings needs to be applicable to the fifth generation of cellular networks, as well as extensions to current generation standards. The application layer communication protocols Constrained Applications Protocol(CoAP), Message Queue Telemetry Transport(MQTT) and Hypertext Transfer Protocol(HTTP) used on multiple modem modules, are investigated in a quantitative approach in deductive survey experiments, testing a variety of what is concluded to be typical sensor and actuator scenarios. The goal with the survey, is to ultimately select the protocol that shows to be the most suitable for a project to build a prototype platform for embedded mobile devices in the shape of publicly shared bikes in a city. This prototype is described and its architecture and design decisions are presented and argued for. The survey discovers that CoAP is the most suitable protocol for the purpose of the thesis, and proceeds to show how it is applied to the described platform.

This thesis examines the popular yé-yé phenomenon and its role in articulating a vision of modern France in the aftermath of decolonization. Yé-yé, a teen-oriented and music-based popular culture that flourished from roughly 1962-1966, was in a unique position to define what it meant to be young in 1960s France. I argue that the yé-yé popular culture, through its definition of youth, provided an important cultural channel through which to articulate a modern French identity after the Algerian War (1954-1962). Using a combination of advertisements, articles, and sanitized depictions of teenage pop singers, the yé-yé popular culture constructed an idealized vision of adolescence that coupled a technologically-savvy and consumer-oriented outlook with a distinctly conservative, apolitical, and inclusive social stance. It reflected France's reorientation toward a particular technological and consumer modernity while simultaneously serving to obscure France's recent colonial past and the dubious legacy of imperialism. To contextualize yé-yé, this thesis begins by examining the blousons noirs (black jackets) and the societal anxieties that surrounded them in the early Fifth Republic (1958-1962). By tracking the abrupt shift from the blousons noirs to yé-yé in predominant media representations of youth, this thesis provides a unique vantage point with which to interpret dominant discourses of the Gaullist Fifth Republic and its attempt to reinvent France into a modernized and decolonized consumer republic. As the work suggests, it was not a coincidence that the optimistic yé-yé youth, unburdened by the tribulations of France's recent past, appeared in full force within months following the recognition of Algerian independence in 1962.
