La problématique de l'information territoriale et ses enjeux majeurs dans les pays du Sud : stratégie, méthodologie et projet pilote dans un pays en développement, le Mali by Alain Bessiba Dakouo( )

In Africa, decentralization takes place in contexts that vary from country to country: the need to reform the Government following a crisis, the desire to establish local democracy to compensate for central or even dictatorial power, sometimes even the Government 's inability to provide basic socio-economic services such as health, education, drinking water, etc.In West Africa, decentralization was often accompanied by a redrawing of territories in the 1990s. Most West African countries have created three levels of local authorities: the Region, the Department (Cercle in Mali) and the Commune. This leads to a need for territory management and planning on several scales (inventory, monitoring of the environmental impact of development, sanitation, natural resource management, rural economic development, health, education, hydraulics and risk management). In the context of a growing need for information, development partners recognize the usefulness of the Geographic Information System (GIS) as a tool for decision making. The creation of different ministries in connection with geographic information in Mali requires pooling of skills centered on geomatics. Indeed, while each Institution and sectoral ministry has its own thematic data, their valuation is hampered by a high dispersion and disparity of geographical and cartographic data.How to share a common geospatial and territorial system across a town hall, a local authority, an NGO, the Government as well as other partners working on the same territorial? What territorial information strategy for a country like Mali?The aim of this thesis is to create, according to the concepts, methods, and technologies of current geography and statistics, a tool to support decision making in a context of overlapping responsibilities/actions and decentralization, designed to take a decisive step forward for the benefit of local territorial planning, by making coherent and available the geolocalized data necessary for an effective spatial planning policy. This strategic perspective implies going back to the distribution of powers, the ratio between free and paid software, participative information (societal, social, ethnic aspects, etc.) and the development of geographical information in Mali.An information strategy is in fact an essential prerequisite for any planning and development strategy. This thesis is an innovative project that will aim to provide answers on the implementation of such a strategy of multi-source and multi-stakeholder spatial information management in a developing country
Géométrie et topologie des processus périodiquement corrélés induit par la dilation : Application à l'étude de la variabilité des épidémies pédiatriques saisonnières by Maël Dugast( Book )

Each year emergency department are faced with epidemics that affect their organisation and deteriorate the quality of the cares. The analyse of these outbreak is tough due to their huge variability. We aim to study these phenomenon and to bring out a new paradigm in the analysis of their behavior. With this aim in mind, we propose to tackle this problem through geometry and topology: the variability process being periodically correlated, the theory of dilation exhibit a set of matrices that carry all the information about this process. This set of matrices allow to map the process into a Lie group, defined as the set of all curves on a manifold. Thus, it is possible to compare stochastic processes using properties of Lie groups. Then, we consider the point cloud formed by the set of dilation matrices, to gain more intuitions about the underlying process. We proved a relation between the temporal aspect of the signal and the structure of the set of its dilation matrices. We used and developped persistent homology tools, and were able to classify non-stationary processes. Eventually, we implement these techniques directly on the process of arrivals to detect the trigger of the epidemics. Overall we established a complete and a coherent framework, both theoretical and practical

Méthodologie de traitement et d'analyse de signaux expérimentaux d'émission acoustique : application au comportement d'un élément combustible en situation accidentelle by Oumar Issiaka Traore( )

1 edition published in 2018 in French and held by 1 WorldCat member library worldwide

L'objectif de cette thèse est de contribuer à l'amélioration du processus de dépouillement d'essais de sûreté visant étudier le comportement d'un combustible nucléaire en contexte d'accident d'injection de réactivité (RIA), via la technique de contrôle par émission acoustique. Il s'agit notamment d'identifier clairement les mécanismes physiques pouvant intervenir au cours des essais à travers leur signature acoustique. Dans un premier temps, au travers de calculs analytiques et des simulation numériques conduites au moyen d'une méthode d'éléments finis spectraux, l'impact du dispositif d'essais sur la propagation des ondes est étudié. Une fréquence de résonance du dispositif est identifiée. On établit également que les mécanismes basses fréquences ne sont pas impactés par le dispositif d'essais. En second lieu, diverses techniques de traitement du signal (soustraction spectrale, analyse spectrale singulière, ondelettes. . . ) sont expérimentées, afin de proposer des outils permettant de traiter différent types de bruit survenant lors des essais RIA. La soustraction spectrale s'avère être la méthode la plus robuste aux changements de nature du bruit, avec un fort potentiel d'amélioration du rapport signal-à-bruit. Enfin, des méthodes d'analyse de données multivariées et d'analyse de données fonctionnelles ont été appliquées, afin de proposer un algorithme de classification statistique permettant de mieux comprendre la phénoménologie des accidents de type RIA et d'identifier les mécanismes physiques. Selon l'approche (multivariée ou fonctionnelle), les algorithmes obtenus permettent de reconnaître le mécanisme associé à une salve dans plus de 80% des cas
Résultats de convergence pour les inéquations variationnelles et applications en mécanique du contact by Ahlem Benraouda( )

1 edition published in 2018 in French and held by 1 WorldCat member library worldwide

The topic of this thesis concerns some convergence results for variational inequalities with applications in the study of boundary value problems which describe the contact between a deformable body and a foundation. The thesis is divided into two parts. In the first part, we are interested in the analysis of quasivariational inequalities, with or without history-dependent operators, in Hilbert spaces. We prove some convergence results related to a perturbation of the set of constraints and a penalty method, as well. Moreover, for a class of history-dependent quasivariational inequalities we study a dual formulation for which we present existence, uniqueness and equivalence results. The second part is devoted to applications of these abstract results in the study of six contact problems with elastic, viscoelastic and viscoplastic materials, both in the static or quasistatic case. The contact conditions we consider are the Signorini condition, the normal compliance condition with unilateral constraint, the unilateral constraint condition with yield limit. Finally, we study a number of optimal control problems associated to some contact models. For these problems we provide existence and convergence results

Virtualisation des pratiques d'enseignement en FOAD entre contexte et média : le cas du réseau Pyramide by Abir Hanafi( )

1 edition published in 2011 in French and held by 1 WorldCat member library worldwide

This doctoral thesis is a descriptive mixed study which articulates both qualitative and quantitative data. In a heuristic goal for the study of the teaching practices by Bru and according to the works of Tardif and Lebrun on the teaching and learning paradigms, the research aims at identifying the homogeneity and heterogeneity aspects of distance teaching practices of a synchronic distance learning network, the Pyramide network. The framework allowing the data analysis of the research rests on three main axes: the teaching practices of a distance learning structure, the organizer of the teaching practices and the various approaches of e-learning. The hypothesis of the research is based on the cross study of these axes. The research protocol is based on a questionnaire, the scale of Likert and semi-structured interviews. The analysis of the quantitative data allowed the definition of key factors for homogeneity and heterogeneity of the practices through new organizers such as interaction, sense of mastering technological tools and pedagogic innovation within the Pyramide structure. The research confirms the hypothesis that the e-training practices are organized around thirty axes that we have defined following the analysis of the trainers' statements. However, it does not confirm the hypothesis that the Pyramid network is an organizer of homogeneity in spite of the strong character of the system which articulates structured pedagogic methods (AFT, TLP, TLT, visio) and an explicit pedagogic discourse rightfully centered on the learner in the teaching/learning situation. Overall, our research shows that pedagogic innovation is far from a reality in FOAD and that many teachers still favour the teaching paradigm over the learning paradigm
