Повний текст джерелаModern global changes, such as climate change and the sixth mass extinction, are profoundly disrupting our societies and ecosystems. New technologies, including machine learning, are both aggravating factors and potential means of mitigating the challenges posed by these changes. In 2015, the United Nations established the Sustainable Development Goals to assess the ecological impact and the risks for populations, revealing that the countries of the South are the furthest from achieving the objectives of this framework. Countries with limited digital infrastructures deploy less machine learning models, encountering a problem of context shift due to inconsistency between training and deployment data. In computer vision, this shift is exacerbated by the absence of data from southern countries in the training sets, leading to reduced model performance.In this thesis, we bridge the gap between artificial intelligence for sustainable science and the inclusivity of computer vision systems. We show how previous approaches to demonstrating the lack of inclusivity of current vision systems have overlooked important aspects of the problem, such as the formalisation of geographical bias and the metrics that reflect its impact. This has led us to propose a protocol for formalising bias, based on the identification of a source, a type and an impact in order to characterise it. This protocol has been implemented for geographical bias, initially on synthetic data. As known synthetic databases do not have a geographical bias, we create synthetic datasets with geographical biases, inspired by previous synthetic modifications of the MNIST database. We use these to test the implementation of our protocol and demonstrate its usefulness. We then experiment with the protocol on real data for characterising western bias in vision systems, and find that the results obtained are different from those expected, going against observations in previous academic work. We carry out a visual analysis of these results at different levels of granularity in an attempt to understand them and to propose possible themes for future research. In the end, we highlight the presence of concomitant biases, elements that make up the geographical bias but have different impacts that the main entity. These concomitant biases prevent the characterisation of the geographical bias by influencing the predictions of the models.We therefore show how the problem of characterising geographical bias is more complex than it might at first appear, what the current pitfalls are and what avenues are being pursued to remedy the problems encountered. Overall, we offer the scientific community tools to better understand the problems of deploying models in developing countries, in order to better understand the challenges of these deployments for applications in sustainable science

Belle, Pierre. "Contribution des processus hydrologiques et hydrogéologiques aux glissements de terrain de grande ampleur : application au contexte tropical de la Réunion." Thesis, La Réunion, 2014. http://www.theses.fr/2014LARE0022/document.
Повний текст джерелаThe landslide activity is commonly controlled by the variation of hydraulic head inside the instable mass. Thus, the hydrogeological study of landslides is an essential step to predict landslide dynamic, and for the remediation choices. However, the aquifers developed in landslide are generally complexes. Actually, the comprehension of landslide hydrogeological functioning is a major problematic, especially for the deep-seated landslides.Under humid tropical climate, the Salazie landslides (Reunion Island) allow to implement an interesting study to characterized deep-seated landslide hydrogeology and functioning. In this study, we performed a multidisciplinary approach, combining geology, hydrochemistry and numerical modeling (global and deterministic);The geological study allows the construction of the deep seated landslide geological model (Grand Ilet sector). The Grand Ilet landslide, corresponding to 175 Mm3, is the most active part of deep seated instability whose the total volume is estimated at 370 Mm3. The volcano-detritic lithologies (i.e basic breccia) constitute the main geological formation of the unstable mass. This breccia is a present-day reactivation of an old destabilization (> 350 Ma). Furthermore, the extensive deformation generated by the landslide activity allows the formation of decompressed zones.Inside breccias, a continuous aquifer is identified. Here, the groundwater flows are controlled by the geometry of the landslide base. Natural land cover, soils properties, unsaturated zone thickness and warm temperature limit the groundwater recharge. Only the intense rainfall episode (80 mm/event) can generated the recharge of landslide aquifer. During these events, rapid transfers circulating inside the decompressed zones have a significant effect on hydraulic charge variations. A slow component is infiltrated inside the porous medium of breccias.The inverse modeling methods with bimodal Gaussian-Exponential transfer function is applied to study the Salazie landslides dynamic. The results show that landslide speed variations are directly controlled by groundwater level variations during the hydrologic cycle (recharge and recession stage). Consequently, the inverse model is a powerful tool for predicting deep-seated landslide movements and for studying how they function

Повний текст джерелаWireless Sensor Networks (WSN) allow a multi-parameters monitoring of small extend areas thanks to cooperative data acquisition, transfer and processing. In order to combine WSN with a precise positioning of the receivers within the network using single frequency GPS modules, the Geocube has been developed by the French National Institute of Geographic and Forest Information (IGN-France). The first part of this work focused on GPS data management and processing to allow the relative positioning of the Geocubes within a local network. To this end, a processing method customized for Geocube data and WSN environment was developed. It is based on the use of GPS carrier phase double differences and a Kalman filtering. Due to the basic GPS antenna used into the Geocube to minimize its price and its size, multipath affect position time series. Various strategies are proposed for multipath mitigation, and finally a sub-centimeter to millimeter level accuracy is reached for relative positioning depending on measurement conditions.The second part of this work was devoted to the use of Geocube networks for geophysical structures monitoring. Two test sites were selected: the Super-Sauze landslide (Ubaye valley, Alpes de Haute-Provence, France) and the Argentière glacier (Mont-Blanc massif, Haute-Savoie, France). The dynamics of the studied areas was investigated at a sub-daily time scale thanks to the high accuracy and the high time resolution of positioning time series derived from Geocubes. In addition, positioning data were acquired quite everywhere a deformation measurement was needed thanks to the low-cost of Geocubes and their easy set up

Повний текст джерелаThis PhD thesis focuses on the controls of the gravitational processes transferring the carbonate production of the platform towards the basins. This work consists in 1) a geological synthesis of the gravity-driven sedimentation in carbonate systems and a typology of favorable configurations for the distal transfer of coarse material 2) an innovative numerical modeling workflow combining the forward stratigraphic modeling and the computation of the mechanical stratigraphy. It estimates the instability mechanisms during the evolution of the system. This work is based on two Plio-Quaternary analog cases: The Great Bahama Bank (GBB) Western leeward slope and the Exuma Sound/San Salvador deep basin and major canyon system, which constitutes an exceptional conduit of distal transport of carbonate sands to the abyssal plain. A common characterization of gravitational transfer processes was established for these two zones. Oedometer and triaxial tests were conducted for the determination of geomechanical parameters of the sediments. The numerical modeling workflow was applied to a 2D transect of the western slope of the GBB over the 1.7-0 Ma interval. It precises the progradation mechanism of the leeward margin related to the development of marginal cemented lowstand wedges. The modeling of the mechanical stratigraphy underlines the control of the gravitational instabilities by the geometry of the platform and fluid overpressures. The latter develop under the effect of transient piezometric head in the emerged platform, promoting the destabilization of the platform margin

Повний текст джерелаThis work is focused on the conceptualization, the modeling and the genericcontrol of mobile robots when moving in off-road contexts and facing slipperyterrains, especially for very accurate tracking and following applications. Thisthesis summarizes the proposed methods and the obtained results to addressthis research issue, first for path following applications (absolute localization)and then for edge and target tracking applications (relative localization). A finalsection of this thesis introduces an adaptive robotic concept and its associatedcontroller allowing the adaptation of the pose (position and orientation) of thechassis with respect to the environment topography.For each application, this thesis introduces a panel of innovative control algorithmsfor controlling skid-steering, two-wheel steering and four-wheel steeringmobile robots. Each algorithm of the panel is described, in this thesis, infour steps : modeling, estimation, control and experiments.The first main contribution of this thesis deals with the slippage estimation.The latter is adaptive and model-based. It also includes the extended kinematicmodeling only or together with the dynamic modeling of the mobile robot toensure a robust estimation of the slippage whatever the speed of the robot, encountereddynamic phenomena or even ground characteristics.The second main contribution deals with the design of a generic control approachfor mobile robots when path following and target tracking. The proposedstrategy is mostly based on a backstepping method and is illustrated inthis thesis via a panel of control laws. When combining this proposed controlapproach with the slippage estimation described above, significant improvedtracking and following performances are obtained (in term of stability, repeatability,accuracy and robustness) whatever the encountered context.All algorithms have been tested and validated through simulations and/orfull-scale experiments, indoor and off-road, with different mobile robots
