Full textThe development of astronomical multispectral sensors allows data of a great richness. Nevertheless, the classification of multidimensional images is often limited by Hughes phenomenon: when dimensionality increases the number of parameters of the model grows and the precision of their estimates falls inevitably, therefore the quality of the segmentation dramatically decreases. It is thus imperative to discard redundant information in order to carry out robust segmentation or classification. In this thesis, we have proposed two methods for multispectral image dimensionnality reduction: 1) bands regrouping followed by local projections; 2) radio cubes reduction by a mixture of Gaussians model. We have also proposed joint reduction/segmentation scheme based on the regularization of the mixture of probabilistic principal components analyzers (MPPCA). For the segmentation task, we have used a Bayesian approach based on hierarchical Markov models namely the hidden Markov tree and the pairwise Markov tree. These models allow fast and exact computation of the a posteriori probabilities. For the data driven term, we have used three formulations: 1) the classical multidimensional Gaussian distribution 2) the multidimensional generalized Gaussian distribution formulated using copulas theory 3) the likelihood of the probabilistic PCA model (within the framework of the regularized MPPCA). The major contribution of this work consists in introducing various hierarchical Markov models for multidimensional and multiresolution data segmentation. Their exploitation for data issued from wavelets analysis, adapted to the astronomical context, enabled us to develop new denoising and fusion techniques of multispectral astronomical images. All our algorithms are unsupervised and were validated on synthetic and real images

Full textIn a context where health economies are increasingly curbed, where specialists are fewer and fewer, while, thanks to screening campaigns, the number of cases to analyze is constantly growing, the task of pathologists is more and more difficult. In addition, early lesions discovered during the screening are often poorly known and / or of very small size which makes the histopathological diagnosis difficult. A similar problem is encountered in hematology with the increasingly widespread practice of systematic blood tests and the difficulty of identifying suspicious cells and rare events in blood smears. It is therefore very important to assess how digital microscopy and automatic processing techniques will be able to help the specialists in their daily practice in the future. This present work is based on the use of virtual slides of histological and cytological preparations, acquired at low or high resolution. It aims at developing and testing several tools for computer assisted diagnosis based on automatic indexing of images. However, the use of virtual slides involves the manipulation of very large data and it is difficult to process, analyze or visualize these images in a classical way. The first objective of the study was to assess the relevance of a global analysis of images, then the contribution of their local analysis, with a dimensional reduction of data by various methods including spectral analysis. These methods have been applied to virtual slides of breast tumors and chronic lymphoid leukemia, two tumor locations whose incidence is a public health problem

Full textMy thesis is devoted to the characterisation of exoplanet atmospheres with the newly-operating James Webb Space Telescope (JWST). Our understanding of exoplanet atmospheres is being revolutionised by the observational capabilities of such an observatory. The scientific outcomes will reach our scientific community and the general public, putting into perspective our knowledge of our own Solar System, the only system that is known to host life. The first part of this manuscript is devoted to an introduction that includes a state-of-the-art review of exoplanet atmospheres characterisation in terms of atomic and molecular composition, structure and dynamics. In this introduction, we focus on transiting exoplanets (when the planet passes in front of or behind its host star in the telescope's line of sight). We provide a description of this observational method and key results that have been obtained over the past two decades. The second part of this manuscript focuses on the molecular composition predictions with the JWST Mid-InfraRed Instrument (MIRI) and its Low-Resolution Spectrometer (LRS) that is meant to carry out atmospheric spectroscopy in an uncharted wavelength range. Here, we present realistic simulations of transiting exoplanets I developed during my thesis, with the MIRI LRS instrument that include various instrumental systematics likely to alter the atmospheric features we are meant to detect in our data [Dyrek+, sub., 2023, Morello, Dyrek+, 2022]. Our main objective is to design a comprehensive simulation tool that enables the community to build robust data reduction methods and to predict molecular detections. The third part of this manuscript is dedicated to the characterisation of the in-flight post-commissioning performances of the MIRI LRS. This work is based on the first exoplanetary transit observed with MIRI of the Super-Earth L168-9b, chosen to be a calibration target. My work focuses on identifying in-flight instrumental systematics that undermine observations' stability and more generally, the study of transiting exoplanets [Dyrek+, sub., 2023]. The final part of this manuscript is devoted to the scientific analysis of photometric and spectroscopic observations of both gas giants and temperate rocky exoplanet atmospheres. Here, I present my contribution on data reduction and analysis to the collaborative work we conducted as part of the Guaranteed Time Observation (GTO) and the Early Release Science (ERS) consortia. In particular, our work on the super-Neptune WASP-107b led to the first mid-infrared detection of sulphur dioxide (SO2) and silicate clouds [Dyrek+, sub., 2023b]. In addition, we conducted the first detection of the thermal emission of the rocky temperate exoplanet TRAPPIST-1b. In this work, we have constrained its brightness temperature, revealing key insights in the presence or not of an atmosphere [Greene+, 2023]. The final chapter of my thesis is dedicated to the prospects offered by JWST and the future Ariel mission, as these two telescopes will provide game-changing observations over the next decades

Full textCurrently, the essential part of the money invested by the industrialist is for the water treatment. In France, most of the 20 billions francs per year devoted to the water treatment is used for the industrial activity. The global management of effluents favour the integration of clean technologies (optimisation, change and modification of the production process) in order to reduce the pollution problem at its source. Our study aims at the introduction of clean technologies in the metal workshops (consumer and generator of water and chemicals) by the development of two data management methods, which lead to two decision support systems. The aim of the first one is to minimise both the water consumption and the wastewater disposal by optimising the production process (optimum yield and efficiency of the rinsing baths. The second one concerns the choice of valorisation techniques considering the valorisation objectives, the effluents characteristics and the parameters limiting the use of the techniques. Our approach fits into a global management method for the metal finishing industry wastewater. Its aim is to limit the quantity of wastewater generated, to valorise effluents and by this way to develop the clean technologies

Full textOur work handles decision support systems based on multidimensional Data Warehouse (DW). A Data Warehouse (DW) is a huge amount of data, often historical, used for complex and sophisticated analysis. It supports the business process within an organization. The relevant data for the decision-making process are collected from data sources by means of software processes commonly known as ETL (Extraction-Transformation-Loading) processes. The study of existing systems and methods shows two major limits. Actually, when building a DW, the designer deals with two major issues. The first issue treats the DW's design, whereas the second addresses the ETL processes design. Current frameworks provide partial solutions that focus either on the multidimensional structure or on the ETL processes, yet both could benefit from each other. However, few studies have considered these issues in a unified framework and have provided solutions to automate all of these tasks. Since its creation, the DW has a large amount of data, mainly due to the historical data. Looking into the decision maker's analysis over time, we can see that they are usually less interested in old data.To overcome these shortcomings, this thesis aims to formalize the development of a time-varying (with a temporal dimension) DW from its design to its physical implementation. We use the Model Driven Engineering (MDE) that automates the process and thus significantly reduce development costs and improve the software quality. The contributions of this thesis are summarized as follows: 1. To formalize and to automate the development of a time-varying DW within a model-driven approach that provides: - A set of unified (conceptual, logical and physical) metamodels that describe data and transformation operations. - An OCL (Object Constraint Language) extension that aims to conceptually formalize the transformation operations. - A set of transformation rules that maps the conceptual model to logical and physical models. - A set of transformation rules that generates the code. 2. To formalize and to automate historical data reduction within a model-driven approach that provides : - A set of (conceptual, logical and physical) metamodels that describe the reduced data. - A set of reduction operations. - A set of transformation rules that implement these operations at the physical level.In order to validate our proposals, we have developed a prototype composed of three parts. The first part performs the transformation of models to lower level models. The second part transforms the physical model into code. The last part allows the DW reduction
