These models enable to simulate artificially weather data that have statistical properties consistent with observed meteorology and climate. Outputs of these models are generally used in impact studies in agriculture or in ecology

Full textNous proposons une revue des méthodes existantes ainsi que notre contribution dans différentes directions. Deux approches sont proposées dans le cadre temporel permettant pour l'une d'éviter l'utilisation de simulations et pour l'autre de prendre en compte les données dont l'information temporelle est incomplète. Nous avons également mis au point une méthode de détection de clusters spatiaux de forme arbitraire permettant d'analyser des données dont on connaît la localisation géographique exacte. Cette approche a été appliquée sur des données particulières, celles obtenues par Imagerie par Résonance Magnétique fonctionnelle. Les perspectives d'analyse spatio-temporelle sont finalement évoquées.

Full textA spatio-temporal representation of event structures is important for an automatic comprehension of disease outbreak reports. The dispersion of components in this type of reports makes it difficult to have such a representation. This work describes an automatic extraction of event structures representation of these texts. We built an information extraction system by using cascaded finite state transducers which allowed the realization of three tasks : the named entity recognition, the arguments annotation and representation and the event structure representation. We obtained with this method a recall between 74. 24% and 100% for the named entity recognition task and a recall between 97. 18% and 99. 54% for argument representation task. Thereafter, we contributed to a normalization task in anaphoric pronouns resolution and in some inferences resolution concerning disease causation, concerned person, spatial and temporal location. We obtained a precision between 70. 83% and 100% for anaphoric pronouns resolution. The evaluation of inferences rules resolutions consisted in finding some counterexamples in the corpora for evaluation

Full textIn this thesis, an important oceanographic variable for the monitoring of the climate is studied: the sea surface temperature. At the global level, this variable is observed along the ocean by several remote sensed sources. In order to treat all this information, statistical methods are used to summarize our variable of interest in global daily map. For that purpose, a state-space linear model with Gaussian error is suggested. We begin to introduce this model on data resulting from having an irregular sampling. Then, we work on the estimation of the parameters. This is based on the combination of the method of moments and the maximum likelihood estimates, with the study of the EM algorithm and the Kalman recursions. Finally, this methodology is applied to estimate the variance of errors and the temporal correlation parameter to the Atlantic ocean. We add the spatial component and propose a separable second order structure, based on the product of a temporal covariance and a spatial anisotropic covariance. According to usual geostatistical methods, the parameters of this covariance are estimated on the Atlantic ocean and form a relevant atlas for the oceanographers. Finally, we show that the contribution of the spatial information increases the predictive behaviour of the model

Full textMassive trajectory datasets generated in modern cities generate not only novel research opportunities but also important methodological challenges for academics and decision-makers searching for a better understanding of travel patterns in space and time. This PhD research is oriented towards the conceptual and GIS-based modeling of human displacements derived from large sets of urban trajectories. The motivation behind this study originates from the necessity to search for and explore travel patterns that emerge from citizens acting in the city. Our research introduces a conceptual modelling framework whose objective is to integrate and analyze human displacements within a GIS-based practical solution. The framework combines conceptual and logical models that represent travel trajectories of citizens moving in a given city. The whole approach has been implemented in a geographical database system, experimented in the context of transportation data, and enriched by a series of query interface manipulations and specific functions that illustrate the potential of our whole framework for urban studies. The whole framework has been experimented on top of the Geolife project and large trajectories datasets available in the city of Beijing. Overall, the findings are twofold: first, it appears that our modelling framework can appropriately act as an extensible geographical database support for the integration of large trajectory datasets; second the approach shows that several emerging human displacements can be explored from the manipulation of large urban trajectories
