L'urbain et la mort : ambiances d'une relation by Pascaline Thiolliere( )

1 edition published in 2016 in French and held by 14 WorldCat member libraries worldwide

Since the turn of the 21st century, the funeral rituality in France undergoes a profound transformation that strongly questions the relationship between death and the city. The more frequent practices of cremation and ashes scattering express a rejection of cemeteries standardisation and constraints. The materiality of the ash leads to dematerialisation and more diffuse localisation of the dead. These are reinforced by the increasing use of digital media (memorial pages, social networks, virtual cemeteries) that open a new space-time framework for sustaining the relationship to the dead and participate in redefining the spatiality of grief. In addition, environmental considerations reveal today a new deviation in the field of funerary both in practice and at the level of representation.We assume that weaving our relationship to the dead passes across the body, its movements and gestures that materialise that relationship while creating a special ambiance. Therefore, from this sensory approach dealing with urban ambiances, constructed and landscaped arrangements are perceived as a way for setting the conditions on spatial, temporal and bodily levels, that participate in establishing the relationship to death and the dead, and partly shape the intimate experience of mourning. Thresholds, rhythms and gestures captured in urban spaces are levers for understanding and designing the relationship between death and the city.In this sense, we identify certain intentionalities that are particularly relevant for the experience of mourning (accompany/support, maintain/sustain, reflect/meditate, travel/progress), which are seen in the light of action possibilities related to the built and landscaped environment. This work helps to highlight the different gaps and resources, and to consider renewing the criteria upon which the design processes of spaces related to death on architectural and urban scales is based
Étude sur la normativité précontractuelle : recherche à partir des fautes commises en contractant by Motahareh Fathisalout( )

2 editions published in 2015 in French and held by 4 WorldCat member libraries worldwide

Absent as such in the discourse of French civil lawyers, the pre-contractual normativity is a legal phenomenon. Its comprehension supposes temporarily suspending the usual reasoning by which a jurist apprehends the pre-contractual period.Revealed through mistakes committed during pre-contractual negotiations, pre-contractual normativity is distinct from general and abstract normativity of the pre-contractual period and indicated in various provisions of the Civil Code (art. 1109 et seq.) and jurisprudential principles (e.g. good faith). As it is concrete, pre-contractual normativity firstly appears as a normative relationship, established between negotiators in the process of negotiating, whether the contract is finally signed or not. This relationship is the material reality of this particular normativity. Secondly, pre-contractual normativity sends back to a norm. As it is endogenous, it is revealed in the evolving environment, in which the negotiators voluntarily place themselves to settle the content of their future contract.Pre-contractual normativity is where a specific pre-contractual norm and a relationship forged between negotiators meet. It renders ineffective the theory of sources of obligations, since the latter, which is known for listing the sources of normativity, fails to explain the former with a single source. Pre-contractual normativity is eclectic and complex and thus, defies a single theorization in the way it is presented. Created in the process of a normative discussion which supposes considering negotiators in the relationship that unites them to one another, the concrete pre-contractual norm is achieved, case-by-case, under the supervision of a judge, who afterwards recognizes a presence or absence of such a norm at the end of a debate in which the negotiators - who have become party to the case - actively take part. The aim is to put forward the interests that stir them during the negotiations and that they now intend to have the judge's favor in his balancing of interests.The demonstration of pre-contractual normativity and its modus operandi are hypothesis of quasi-law and invite jurists to rethink the paths to normativity to give way to the completely inherent sociability that characterizes the law
L'adoption et les droits de l'enfant en Afrique francophone : réflexions sur les droits malien et sénégalais by Mahamane Coulibaly( )

2 editions published in 2015 in French and held by 4 WorldCat member libraries worldwide

The Laws in Mali and Senegal concerning child adoption have considerable weakness to which this thesis tries to deal with. In fact, Malian and Senegalese Law-makers, in their effort of codifying the adoption law, have unfortunately adopted French legislation on adoption, ignoring the socio-legal standards of their own countries. In these countries, there are two forms of legal adoption based on the French model. In Mali, there are direct descendant adoption and adoption for protection; whereas in Senegal there are plenary and short-term adoption. Such legislative typology concerning adoption suffers a lack of balance and coherence in its structure and purpose as well. Consequently, it does not provide strong protection of the rights of both Malian and Senegalese Children. With legal adoption, coexist in both countries, circumstantial adoption to which resists the Law. So, traditional and recurrent practice of Children in custody in families in these countries remains a bizarre area sheltered by Law. These circumstantial adoptions correspond to a kind of social and affective parenthood which is supposed to make law. By legalizing circumstantial adoption, Malian and Senegalese law-makers would create a possibility of the creation of an adoption model without direct descendances according to Malian and Senegalese contexts which are more favorable to intra-family adoption. Some fundamental rights of the Child would be better guaranteed. However, the laws concerning international adoption in both countries is in its embryonic stages and need to be better established. In this perspective, it is worth maintaining and reinforcing the key principles according to the Hay Convention of 1993 concerning international adoption, and insert some controversial rules and laws into domestic legislations of the two countries concerning international adoption where the deep interest of a child in family-forfeiture is most respected. These new rules will permit to determine the legislative capability and efficiency in Mali and Senegal concerning decisions made abroad by countries which are not concerned by the Hay Convention of 1993
Un intellectuel communiste illégitime : Roger Garaudy by Didier Gauvin( )

2 editions published in 2018 in French and held by 4 WorldCat member libraries worldwide

Après avoir atteint l'excellence en tant qu'intellectuel de parti stalinien pendant la Guerre froide, Roger Garaudy s'est construit comme intellectuel "véritable" contre la doxa du PCF qu'il était pourtant chargé d'incarner, à la faveur de son autonomisation suite au choc du XX° Congrès du PCUS périmant sa foi en Staline. C'est ainsi que la résurgence progressive de son habitus théologico-philosophique a fait de lui l'homme du dialogue par excellence adapté à la démarginalisation du PCF dans le champ intellectuel des années 1960. Mais si son engagement sur la tagente hérétique a fait de lui l'un des intellectuels communistes poussant le plus loin le projet de rénovation du PC en offrant une véritable stratégie alternative à celle du Parti après 1968, l'exclusion qui s'en est suivie s'est traduite par un retour du refoulé religieux qui, couplé à la posture prophétique d'un intellectuel désormais excentré dans le champ intellectuel français, a largement contribué à la délégitimation de l'ancien philosophe du PC avant même sa radicalisation ultime qui a achevé de le disqualifier suite à sa condamnation pour négationnisme
Les antécédents intra et inter-organisationnels du processus d'adoption des achats responsables by Lauriane Robert( )

2 editions published in 2016 in French and held by 3 WorldCat member libraries worldwide

Purchasing Social Responsibility (PSR) is a topic of current interest. Recent literature development on this topic reflects the increasing interest amongst researchers. However, the existing literature fails to provide a comprehensive understanding of the PSR implementation process, which is also an issue of interest from a managerial perspective. This thesis aims to address this gap by identifying the antecedents (drivers and barriers) to PSR adoption process. We provide an original conceptual framework, which identifies intra-organizational antecedents to a sustaining adoption and sheds light on the important role of collaboration in buyer-supplier relationship.The empirical methodology is based on five case-studies with companies at different stages of PSR adoption process.The results show that intra-organizational antecedents play a critical role in achieving the set-up and operating phases, while inter-organizational antecedents (buyer-supplier collaboration) appear to be essential for the sustaining phase. This research provides comprehensive guidance for activating these leverages throughout the PSR implementation process, and it helps firms identify their level of PSR adoption
Modélisation et optimisation de la maintenance et de la surveillance des systèmes multi-composants - Applications à la maintenance et à la conception de véhicules industriels by Romain Lesobre( )

2 editions published in 2015 in French and held by 3 WorldCat member libraries worldwide

This thesis research work focuses on the maintenance operations scheduling and the development of a design methodology for maintenance. The aim is to suggest a customized maintenance service offer for each vehicle and able to adapt to user constraints. In the transport industry, these constraints are defined by a limited number of maintenance opportunities and vehicle unplanned stops with significant financial consequences. This service offer should enable both to improve the vehicle uptime and to reduce the maintenance impact on operating costs. In this framework, the developed maintenance policy ensures, with a given risk probability, maintenance free operating periods for a multi-component system. During these periods, the system should be able to carry out all its assigned missions without maintenance actions and system fault. And the end of each period, the considered policy evaluates if a maintenance action is required to ensure maintenance-free and fault-free operation on the next period with a specified confidence level. When a maintenance action is mandatory, decision criteria considering the maintenance costs and the maintenance efficiency are used to select the operations to be performed. This form of dynamic clustering, called time-driven clustering, integrates both the component reliability models, the system structure and the available monitoring information. In our case, the monitoring information refers to the component state information and information on the component operating conditions. The process flexibility makes possible to make a maintenance decision in using different information levels for system components. The policy parameters, namely the period length and the confidence level value, are optimized based on the total maintenance cost. This cost, evaluated on a finite horizon, is composed of directs costs related to maintenance operations and indirect costs generated by system immobilizations. In order to reach a significant operating costs reduction, the maintenance policy optimization alone is not sufficient. It is essential to have a broader approach to involve the system and its maintenance since the conception. In this context, the developed design methodology suggests to prioritize the components impact on the operating costs. This prioritization is performed thanks to a defined importance factor. Then, multiple design options are evaluated by simulation in priority component. The selected options lead to reduce the operating costs. This work contains simulation results that illustrate the methods mentioned above. Moreover, a heavy vehicle sub-system is used as a test-case
Contrôle des applications fondé sur la qualité de service pour les plate-formes logicielles dématérialisées (Cloud) by Ge Li( )

2 editions published in 2015 in French and held by 3 WorldCat member libraries worldwide

Le « Cloud computing » est un nouveau modèle de systèmes de calcul. L'infrastructure, les applications et les données sont déplacées de machines localisées sur des systèmes dématérialisés accédés sous forme de service via Internet. Le modèle « coût à l'utilisation » permet des économies de coût en modifiant la configuration à l'exécution (élasticité). L'objectif de cette thèse est de contribuer à la gestion de la Qualité de Service (QdS) des applications s'exécutant dans le Cloud. Les services Cloud prétendent fournir une flexibilité importante dans l'attribution des ressources de calcul tenant compte des variations perçues, telles qu'une fluctuation de la charge. Les capacités de variation doivent être précisément exprimées dans un contrat (le Service Level Agreement, SLA) lorsque l'application est hébergée par un fournisseur de Plateform as a Service (PaaS). Dans cette thèse, nous proposons et nous décrivons formellement le langage de description de SLA PSLA. PSLA est fondé sur WS-Agreement qui est lui-même un langage extensible de description de SLA. Des négociations préalables à la signature du SLA sont indispensables, pendant lesquelles le fournisseur de PaaS doit évaluer la faisabilité des termes du contrat. Cette évaluation, par exemple le temps de réponse, le débit maximal de requêtes servies, etc, est fondée sur une analyse du comportement de l'application déployée dans l'infrastructure cloud. Une analyse du comportement de l'application est donc nécessaire et habituellement assurée par des tests (benchmarks). Ces tests sont relativement coûteux et une étude précise de faisabilité demande en général de nombreux tests. Dans cette thèse, nous proposons une méthode d'étude de faisabilité concernant les critères de performance, à partir d'une proposition de SLA exprimée en PSLA. Cette méthode est un compromis entre la précision d'une étude exhaustive de faisabilité et les coûts de tests. Les résultats de cette étude constituent le modèle initial de la correspondance charge entrante-allocation de ressources utilisée à l'exécution. Le contrôle à l'exécution (runtime control) d'une application gère l'allocation de ressources en fonction des besoins, s'appuyant en particulier sur les capacités de passage à l'échelle (scalability) des infrastructures de cloud. Nous proposons RCSREPRO (Runtime Control method based on Schedule, REactive and PROactive methods), une méthode de contrôle à l'exécution fondée sur la planification et des contrôles réactifs et prédictifs. Les besoins d'adaptation à l'exécution sont essentiellement dus à une variation de la charge soumise à l'application, variations difficiles à estimer avant exécution et seulement grossièrement décrites dans le SLA. Il est donc nécessaire de reporter à l'exécution les décisions d'adaptation et d'y évaluer les possibles variations de charge. Comme les actions de modification des ressources attribuées peuvent prendre plusieurs minutes, RCSREPRO réalise un contrôle prédictif fondée sur l'analyse de charge et la correspondance indicateurs de performance-ressources attribuées, initialement définie via des tests. Cette correspondance est améliorée en permanence à l'exécution. En résumé, les contributions de cette thèse sont la proposition de langage PSLA pour décrire les SLA ; une proposition de méthode pour l'étude de faisabilité d'un SLA ; une proposition de méthode (RCSREPRO) de contrôle à l'exécution de l'application pour garantir le SLA. Les travaux de cette thèse s'inscrivent dans le contexte du projet FSN OpenCloudware (www.opencloudware.org) et ont été financés en partie par celui-ci
La communication publique et ses évolutions. La localisation de la communication de l'Etat à travers l'exemple de la sécurité routière by Welore Tamboura( )

2 editions published in 2017 in French and held by 3 WorldCat member libraries worldwide

The objective of this thesis, in information and communication sciences, is to question the issues related to the location of prevention communication during the public policy about road safety in France.In France,the emergence of public communication of the state is recent. It dates back to the 1970s with the policy of creating new towns and the introduction of communication as a factor of change of administration and modification of the behavior of individuals. This last aspect shows the belief in a "power of influence" of the publicized communication on the part of the public authorities and hence the resulting tendency to analyze public communication of the State through its sole dimension “The media ". Without obscuring the role of the media in public communication, the analysis focuses on the various underlying dimensions emerging from the localization of prevention communication on the theme of road safety, the media of which seem to reflect only “a part.This localization approach brings together the logics, the strategies of the actors and the representations that confront each other and show that issues of road safety emerge from other issues that go beyond the initial framework, in particular that of the quest for The visibility, the legitimisation of public action through communication, the normalization of behavior through the management of individual conduct and the governance of territories at a time when the state seems to lose More and more prerogatives for the benefit of local and regional authorities.The diachronic approach of the "institutionalization" of state communication on the issue of road safety and its stakes shows three key periods: the 1970s with a "technical" approach to road safety and the birth of First prevention campaigns (first in the voluntary sector). Then the 1980s and the first decentralization movements marked a new orientation in the framework of public action concerning road safety, which is read not only through the internal structuring of the State apparatus (restructuring of its external services ) But also through its territorial deployment and the transfer of powers to local authorities. Finally, the 2000s saw the strengthening of the "coercive" dimension and the setting up of a set of tools in this sense.The analysis of the evolution of public communication on the issue of road safety and its location shows that it is intrinsically linked to the evolution of state administration (at the structural and political levels) Where attempts at successive (and not necessarily different) reorientations of this policy, the intervention of actors with different interests and logics that do not necessarily bring about a redefinition of the communication policy (at least not in its most visible part ), The importance of the mobilization of quantitative tools, reactivated by the finance laws as well as the imperatives at European level
Musique et industries médiatiques. : Construction et mutations d'une musicalisation médiatisée à la télévision (1949-2015) by Guylaine Gueraud Pinet( )

2 editions published in 2018 in French and held by 3 WorldCat member libraries worldwide

This doctoral thesis questions the relationship between music and the media from a communicational perspective. Relying upon the notion of mediatized musicalization, this research work offers an analysis of musical integrations featured on French television from 1949 to 2015. Building upon intermedia and integeneric foundations, the musical setting of French television programs bears witness to the ever increasing industrialization of two sectors of the cultural industries since the 1980's: the audiovisual sector and the recorded music sector. In order to fully appreciate the issues at stake here, a composite methodology has been adopted mixing investigative research on the work of video editors (historiographical readings, semi-directive interviews) and corpus analyses (statistical analyses and thematically-oriented content analyses). One of the conclusions that can be drawn from these analyses is that, in a context of rationalized creation, musical integrations indicate that the symbolic value of music is taken into consideration as part of a wider strategy aimed at grabbing the attention of the public. These changes, noticeable in the contents, have led to the multiplication and to the growing circulation of musicalized images, thus reveal the involvement of the media in our industrialized culture
Proposition d'interface Science-Société pour la gestion intégrée de la ressource en eau dans un contexte de changements climatiques by Eve Leroy( )

2 editions published in 2015 in French and held by 3 WorldCat member libraries worldwide

Water is a vital need for Human and each society have to manage it at best to meet this basic need today and in the future. Current climatic changes and especially global warming strongly impact hydrosystems and economical activities of mountainous areas, forcing these territories to adapt to these new conditions. Socio-economic development choices have also a great importance in water shortages occurrence. In this thesis a model coupling representations of water resources and and socio-economic activities was built. It allows to explore both climate change impacts and socio-economic choices impacts on water resources availability in a mountain territories at different time scales. All combinations of climate change and socio economic choices scenarios are testable. The Megève ski resort station in France was used to develop and apply the hydro-anthropic model. The latter must contribute, as a decision support tool, to climate change adaptation policies developpement. Therefore, the tricky question of knowledge transfer between Science and Society is addressed in this thesis. The scientific model developped was introduced in Serious-Games as an interface proposal. Through the C3-Alps projet which financed this thesis, others knowledge tranfers for climate change adapation in the Alps were also addressed
Golden Snow. Ségrégation et entre-soi dans les stations de sports d'hiver haut de gamme en Autriche, en France et en Suisse. by Lise Piquerey( )

Winter sports resorts are tourist places where the dynamics of arrangement were studied for several decades. If the strategies of development of the tourist system in places considered capable of being able to support this activity are one of main stakes in certain local economies, this thesis wishes to question not the tourism in the prism of the economy or the arrangement, but in the prism of the distinction. The distinction, the concept in the interface of the social geography and the other human sciences as the sociology, allows to question the whole tourist system, both in its urban, economic and social character. The interest of this angle of approach also is to replace the individual, in its complete identity within these places which have to tend to integrate the various socio-economic groups which are located there. In order to achieve this goal, we suggest questioning the place of the clienteles from superior socioeconomic categories, from permanent inhabitants and from seasonal workers, both in the heterogeneous profiles within top of the range winter sports resorts. We shall approach the distinction through two angles: the one within the tourist places market and the one within social categories in these places, who would try to disregard any considerations under the social hierarchy. Geographical research before any, this thesis will approach the distinction with regard to two strong notions: the segregation and the “entre-soi”, by questioning the accessible place by each one within the urban space of winter sports resorts, considered as the spatial power. We suggest leading this study in ten winter sports resorts top of the range, localized in Austria, in France and in Switzerland. This state diversity will also allow to question the strategies of distinction with regard to legislations in force in every country. From the abstract frames presented in the part 1 (chapter 1: state of the art of the segregation and the “entre-soi”; chapter 2: sampling of the studied stations and the methodological approach; chapter 3: research questions), we shall approach the strategies of distinction through several angles of approaches: the tourist inheritance and the singular urban forms which he produced (chapter 4), urban space staging in tourist purpose (chapter 5) and the regimes of visibilities of the socioeconomic categories in the urban landscape of the wealth (chapter 6). This second part will allow to bring to light the existence of distinction of interfaces present within the winter sports resorts top of the range: thresholds, among which the modalities of production, so social, symbolic as material and the spatial constraints which they lead will be respectively handled in chapter 7 and chapter 8 (part 3). Finally, this thesis proposes a social geography of the tourism, more than a geography of the tourist practices
Lien familial et droit pénal by Camille Montagne( )

2 editions published in 2015 in French and held by 3 WorldCat member libraries worldwide

Studying the family link from a criminal law perspective may seem paradoxical at first sight. Yet this is not the case since the confrontation between these two concepts is as ineluctable as is it necessary. The examination of the impacts of the familly link on the repressive rules falls within a multidisciplinary approach and sheds light on two conceptions, whose limits are constantly changing. The purpose of this study is to analyse the current phenomenon of transformation in the criminal protection of families throught observation and research; and to give a new orientation towards future implementations. The study reveals the existence of an overall desinterest of the the repressive field in the family link precisely where its consideration is a fondamental criterion in the construction and consistent implementation of criminal rules. The purpose of this research is to analyse the existing body of repressive laws and regulations currently in use as well as to establish an unprecedented classification of family offenses. The creation of a fonctional typology of family offenses in criminal law will make it possible to provide tailored legal tools to deal with this dilemma and to implement a specific criminal policy regarding the family. This endeavour challenges the very existence of the family link in criminal justice and demands not only that it be reintegrated into criminal law at the initial stage of classifying family offenses, but also that it be subsequently taken into consideration when dealing with these offenses
La transition énergétique by Prudence Dato( )

2 editions published in 2016 in French and held by 3 WorldCat member libraries worldwide

La transition vers les énergies renouvelables implique deux types de préoccupations environnementales. Les combustibles fossiles sont épuisables et leur utilisation génère des externalités négatives à travers des dommages environnementaux irréversibles. En outre, il existe des possibilités de synergies entre les mesures d'efficacité énergétique et l'adoption de l'énergie renouvelable dans la mesure où les premières réduisent la demande d'énergie de sorte que la dernière puisse commencer à réduire les émissions futures de gaz à effet de serre. L'objectif principal de cette thèse est d'analyser la transition énergétique optimale dans un contexte de survenance certaine et incertaine d'une catastrophe environnementale et de déterminer les instruments incitatifs au niveau des ménages en vue de stimuler la transition énergétique.La thèse est composée de quatre chapitres qui traitent indépendamment des différentes questions de la transition énergétique. Le premier chapitre met l'accent sur la transition énergétique optimale impliquant des décisions à la fois sur l'adoption de l'énergie renouvelable et de l'investissement dans les technologies d'économie d'énergie, quand il y a un seuil de pollution certain qui déclenche une catastrophe environnementale. Le deuxième chapitre étudie la transition optimale vers les énergies renouvelables quand la survenance de la catastrophe environnementale est incertaine. Le troisième chapitre cherche à comprendre le comportement des ménages par rapport à leurs décisions d'adopter simultanément les énergies renouvelables et à investir dans l'efficacité énergétique. Finalement, le quatrième chapitre examine le rôle des réseaux intelligents dans l'intégration de l'énergie renouvelable intermittente afin de faciliter la transition énergétique
Des villes en projet : les politiques culturelles au cœur du développement métropolitain : une étude comparée du tournant métropolitain de la culture à Barcelone, Bordeaux, Strasbourg et Stuttgart by Pierre Miglioretti( )

The issue of this research is the one to analyze to what extent the cultural action is integrated to the metropolization process, in the sense of a reinforcement of the weight of Metropolis as political stakeholder of globalization. Thus, we will discuss the way culture takes part in the metropolitan strategies in a globalized context, having for consequence to weight on the different imperatives of public action (visibility for public policy, cohesion of urban territories, transparency of public policy, integration to the international exchange system of metropolises,...) Therefore, essentially through the set-up of project, we can evoke the integration of the metropolitan cultural action in a system of constraint due to globalization; system, which partially induces the principles of cultural action and what could be expected of it. This is mainly translated by a process of heteronomization of cultural action, by a progressive integration of cultural policy into the metropolitan strategies, completing the process of instrumentalization initiated in the 80's in favor of economic and social development. This situation is also translated by an evolution of the strategies of actors, of the metropolitan cultural policy. As a consequence we can possibly talk about pluralization of the cultural action. According to each context, this pluralization is more or profound and is heading towards different directions, calling for an important consideration for socio-territorial embodiment logics. Finally, this stresses on the constitution of a new model of cultural public policy for metropolises whom influences is no more, as it was the case for cities, in a sector-based cultural policy inspired by the state-driven action of a ministry for culture, but is now anchored in the cross-sector and territorialized action of the European Union. In a comparative perspective, we are relying on the study of projects intrinsically cultural or impacting on this sector of public action in four european cities : Barcelona, Bordeaux, Strasbourg and Stuttgart
Conception et évaluation des systèmes logiciels de classifications de paquets haute-performance by Peng He( )

2 editions published in 2015 in French and held by 3 WorldCat member libraries worldwide

Packet classification consists of matching packet headers against a set of pre-defined rules, and performing the action(s) associated with the matched rule(s). As a key technology in the data-plane of network devices, packet classification has been widely deployed in many network applications and services, such as firewalling, load balancing, VPNs etc. Packet classification has been extensively studied in the past two decades. Traditional packet classification methods are usually based on specific hardware. With the development of data center networking, software-defined networking, and application-aware networking technology, packet classification methods based on multi/many processor platform are becoming a new research interest. In this dissertation, packet classification has been studied mainly in three aspects: algorithm design framework, rule-set features analysis and algorithm implementation and optimization. In the dissertation, we review multiple proposed algorithms and present a decision tree based algorithm design framework. The framework decomposes various existing packet classification algorithms into a combination of different types of “meta-methods”, revealing the connection between different algorithms. Based on this framework, we combine different “meta-methods” from different algorithms, and propose two new algorithms, HyperSplit-op and HiCuts-op. The experiment results show that HiCuts-op achieves 2~20x less memory size, and 10% less memory accesses than HiCuts, while HyperSplit-op achieves 2~200x less memory size, and 10%~30% less memory accesses than HyperSplit. We also explore the connections between the rule-set features and the performance of various algorithms. We find that the “coverage uniformity” of the rule-set has a significant impact on the classification speed, and the size of “orthogonal structure” rules usually determines the memory size of algorithms. Based on these two observations, we propose a memory consumption model and a quantified method for coverage uniformity. Using the two tools, we propose a new multi-decision tree algorithm, SmartSplit and an algorithm policy framework, AutoPC. Compared to EffiCuts algorithm, SmartSplit achieves around 2.9x speedup and up to 10x memory size reduction. For a given rule-set, AutoPC can automatically recommend a “right” algorithm for the rule-set. Compared to using a single algorithm on all the rulesets, AutoPC achieves in average 3.8 times faster. We also analyze the connection between prefix length and the update overhead for IP lookup algorithms. We observe that long prefixes will always result in more memory accesses using Tree Bitmap algorithm while short prefixes will always result in large update overhead in DIR-24-8. Through combining two algorithms, a hybrid algorithm, SplitLookup, is proposed to reduce the update overhead. Experimental results show that, the hybrid algorithm achieves 2 orders of magnitudes less in memory accesses when performing short prefixes updating, but its lookup speed with DIR-24-8 is close. In the dissertation, we implement and optimize multiple algorithms on the multi/many core platform. For IP lookup, we implement two typical algorithms: DIR-24-8 and Tree Bitmap, and present several optimization tricks for these two algorithms. For multi-dimensional packet classification, we have implemented HyperCuts/HiCuts and the variants of these two algorithms, such as Adaptive Binary Cuttings, EffiCuts, HiCuts-op and HyperSplit-op. The SplitLookup algorithm has achieved up to 40Gbps throughput on TILEPro64 many-core processor. The HiCuts-op and HyperSplit-op have achieved up to 10 to 20Gbps throughput on a single core of Intel processors. In general, our study reveals the connections between the algorithmic tricks and rule-set features. Results in this dissertation provide insight for new algorithm design and the guidelines for efficient algorithm implementation
Étude numérique de la ventilation naturelle, mise en oeuvre d'un modèle fin dans une simulation de thermique du bâtiment by Sébastien Wullens( )

2 editions published in 2015 in French and held by 3 WorldCat member libraries worldwide

The building sector is the global largest energy consumer. To reduce environmental impact of buildings, passive tools must be developed. Still, air conditioning is increasingly used in the DROM-COM. The development of natural ventilation is essential to reverse this trend. Multizone models are not really suited for describing natural ventilation flows. Computational fluid dynamics (CFD) seem to be a promising way too model those flows.This thesis deals with the adaptation of a direct resolution of the Navier-Stokes equations code to describe airflows in buildings. The development, implementation and comparison of different types of pressure boundary conditions on the openings were required. The behavior of a room subjected to natural and mixed convection has been studied thanks to this work. To integrate this model into a building simulation, a “black box” object that transparently calls the CFD code on a remote server from a multizone environment has been developed. Partial cooling of the walls of a cavity subjected to natural convection has been simulated using this method
Approche communicationnelle des rapports entre arts et sciences : le cas des résidences et des festivals. by Cassandre Molinari( )

2 editions published in 2017 in French and held by 3 WorldCat member libraries worldwide

The thesis proposes to analyze the “arts-sciences” residences and the festivals in a communicational perspective. Since 2000's, those events are organized by artistic and scientist institutions, but also by associations of scientific culture. They receive public assistance, from local authorities to international organizations. The research questions the action of strategies of political and social actors on the construction of “arts-sciences” practice and the communication of their products. The emergence of the “arts-sciences” projects is linked to issues concerning territorial development, scientific communication, technological innovation, renewal of scientific popularization and artistic avant-gardism. The communication of the products is torn between the distribution of works of art, the transfer of scientific culture and the promotion of technologies

How are built, to structure and organize courses cultural industries and creative in Burkina Faso? What is their level of development? What are the current challenges they are facing and what are the strategies actors? These are just issues that sets out to answer our research work.The development of cultural industries in Burkina Faso is in operation since independence and has intensified over the past ten years. This dynamic knows the ups and downs depending on the circumstances (environment), actors and public policy.Despite the efforts and progress in the sector there is the low industrialization of culture and embryonic chains character. Meanwhile the hopes of the actors placed in them (cultural industries and creative) for their ability to create wealth and jobs are large and related. Discourses and practices are often contradictory and public policy lack of pragmatism.Faced with this situation, our work is striven is to show the State or the environment in which evolved and are currently changing the industrialization of culture and how the actors at each level of the streams industrial (Book, Music, Cinema and audiovisual, Video games) and the so-called creative industries (Fashion and textile design & Arts and crafts) are organized and structure their sectors to continue to exist in a context of openness, globalization of artistic and cultural works.Finally, the work closes by opening up the current changes that characterize the industrial sectors of culture both at the level of production factors in the strategies of the actors.KeywordsCultural industries ; Cultural and creative industries ; Cultural development ; Dies ; Stakeholder strategies ; Cultural policies ; Public policies ; Economy of culture ; Political economics

More stringent thermal regulations, made necessary the inclusion of mass transfer in building walls and their interaction with heat transfer, particularly for those composed of porous and highly hygroscopic materials.The experimental device consists of two walls mounted and tested on PASSYS orientable cells, with controlled indoor environment, located on the CEA-INES site in Le Bourget du Lac. The wood framed walls, with a wood fiber insulation were tested under different internal and external conditions, depending respectively on internal monitored temperature and humidity, or orientation. The one-year long experimental measurements have shown the influence of moisture fluctuations on the thermal behavior of the tested walls, and also the influence of temperature on the moisture in the walls.A numerical model was used to simulate the phenomena observed in experimental conditions. The model, developed on DYMOLA was firstly validated by a comparison with other existing numerical models, during a benchmark on experimental measurements under controlled conditions. It was then used to simulate experimental sequences on external conditions of this work. Comparing the numerical and experimental results have shown a correlation of the temperature measurements, but a difference for the moisture measurements. Parametric adjustments showed an overestimation of the Hygric inertia combined with an underestimation of the vapor permeability of the numerical model compared to experimental sequences. A mismatch of material properties such as reflected generally in the numerical models with the experimental conditions in which they are recorded is underlined

This thesis is devoted to the usefulness of intangible assets disclosure by French listed companies around new equity issues and its impact on stock liquidity. The growing importance of intangibles for companies' competitiveness and growth, besides of their non-recognition often raises the question of the need to complete financial statements by intangible assets voluntary disclosure. Accounting and finance literature shows changes in external users' information needs and highlights their attention for information related to intangibles. Insufficient communication on these assets accentuates information asymmetry in financial markets. It provides also a fertile ground for wealth transfer from uninformed investors to informed investors, as by exploiting private information, they can derive higher returns at the expense of other investors. This situation leads to a decrease in stock liquidity, and therefore to an increase of companies' cost of capital, which becomes more important around equity issues. The study conducted on a sample of French listed companies issuing new equity over the period 2000-2009 shows a low level of intangibles voluntary disclosure. Furthermore, our analysis shows that intangibles voluntary disclosure reduces spread, and increases trading volume at the announcement of a capital increase
