Full textWe have developed a system capable of generating an information retrieval hypertext structure on a large collection of homogeneous documents by selecting only those noun phrases that are pertinent for navigation. The specification of our hypertext system is based on a real-world application supplied by Electricité de France, that is, browsing a large document base made of costumer letters, along with the associated reply letters. The aim of the navigation in the document base is to help finding consistent answers to any new incoming complaint letter. Our research aims at identifying the linguistic context of interesting noun phrases, extracted automatically, in order to enhance the selection of pertinent cross-document links. Context identification is based on spotting linguistic markers of the expression of solicitations. A new browsing session is booted by the content of any incoming letter, that supplies content elements to compute thematic similarity with any complaint letter stored in the corporate memory

Full textAir pollution contributes to the degradation of the quality of life and the reduction of life expectancy of the populations. The World Health Organization estimates that air pollution is responsible for 7 million deaths per year worldwide. It contributes to the aggravation of respiratory diseases, causes lung cancer and heart attacks. Air pollution has therefore significant health consequences on human life and biodiversity. Over the last few years, considerable progress has been made in the field of microcontrollers and telecommunications modules. These are more energy efficient, powerful, affordable, accessible, and are responsible for the growth of connected objects. In the meantime, the recent development of microelectromechanical systems and electrochemical sensors has allowed the miniaturization of technologies measuring many environmental parameters including air quality. These technological breakthroughs have enabled the design and production in an academic environment, of portable, connected, autonomous air quality sensors capable of performing acquisitions at a high temporal frequency. Until recently, one of the major obstacles to understanding the impact of air pollution on human health was the inability to track the real exposure of individuals during their daily lives; air pollution is complex, and varies according to the habits, activities and environments in which individuals spend their lives. Portable air quality sensors completely remove this obstacle as well as a number of other important constraints. These are designed to be used in mobility, over long periods of time, and produce immediately available granular data, which describes the exposure to air pollution of the person wearing it. Although the measurement modules embedded in these sensors are not currently as reliable as reference tools or remote sensing, when it comes to assessing individual exposure to air pollution, because they are as close as possible to the wearer, they provide the most accurate information, and are therefore an indispensable tool for the future of epidemiological research. In this context, we have been involved in the development and improvement of two air quality sensors; the CANARIN II and the CANARIN nano. The CANARIN II is a connected sensor communicating via Wi-Fi, which reports the concentration of 10, 2.5 and 1 micrometer diameter particles, as well as the environmental parameters of temperature, humidity, and pressure, every minute, making them available in real time. The CANARIN nano is a smaller sensor with the same capabilities of the CANARIN II, while additionally sensing volatile organic compounds levels. The CANARIN nano is able to operate autonomously, as it communicates through the cellular network. Two types of results have been obtained with the CANARIN sensors; on one hand, results produced from their use in real life conditions, and on the other hand, results related to the interpretation and understanding of the measurements produced by the particle sensors. These two sensors were both used in two research projects, in which we have helped deploy several heterogeneous sensor fleets and analyzed the acquired data. Firstly, in the POLLUSCOPE project funded by the French National Research Agency, where 86 volunteers from the general population wore a set of air pollution sensors for a total of 101 weeks, 35 of which the volunteers were also equipped with health sensors. Secondly, in the POLLAR project, where 43 subjects underwent polysomnography and then wore one CANARIN sensor for 10 days, thus allowing for the first time to explore the link between sleep apnea and particulate matter exposure.

Full textIn their natural environment plants are in close interaction with beneficial, neutral, or pathogenic microbes, which are highly dependent on carbon resources exuded by plant roots. Sugar transport, which is a key process of plant physiology, is essential to support the fate of plant-microbe interactions. During evolution, plants have acquired the ability to perceive microbial molecules, initiating specific signal transduction cascades and leading to adapted response for microbe lifestyles (avirulent, virulent, or benefic). Plant survival will depend on the nature of the induced mechanisms. My PhD work, carried out on a simplified experimental system, contributes to the understanding of mechanisms underlying the determinism of plant-microbe interactions. We used Nicotiana tabacum cells in suspension exposed to microbial molecules derived from mutualistic or avirulent microbes. Using such a simplified system, we analyzed elements of the early signaling cascade and sugar fluxes. We have shown that CO4, which is originating from AMF, initiate early signaling components (rbohD-dependent H2O2, cytosolic Ca2+, MAPK activation) as cryptogein, a defense elicitor, but with distinct profile and amplitude. Those two molecules (CO4 and cryptogein) are responsible of different effects on sugar fluxes and the expression of the underlying sugar transporter genes. In addition, we presented an impact of the alteration of clathrin-mediated process on early signaling events triggered by cryptogein, as well as inward sugar fluxes and expression of sugar transporter genes. Finally, in silico analyses of sugar transporter interactome in Arabidopsis thaliana has provided some possible regulation mechanisms through the identification of new candidate proteins involved in sugar transporter regulation. These information open new perspectives towards a better understanding of the cellular and molecular mechanisms involved in plant-microbe interactions
Zhu, Min. "Simulation de systèmes à structure dynamique dans une approche d'ingénierie système basée modèles appliquée au matériel reconfigurable." Thesis, Toulouse 3, 2018. http://www.theses.fr/2018TOU30191.
Full textAs partially reconfigurable technologies develop for embedded systems, the need for a proper model to describe its behavior emerges. Most academic and industrial tools available on the market does not address dynamic structure modeling. The arising of discrete-event modeling, in particular, Discrete Event System Specification (DEVS), propose formal tools for representing and simulating models. DEVS has already extension which handles the dynamic structure modeling. However, the capacities of these existing formalism have limitations. Notably, they do not address the components context aspect. Also, the existing formalisms have not integrated the system engineering approach. System engineering brings beneficial procedures, notably modeldriven architecture which proposes to separate the system description from its execution target. A platform-specific model is formed from a platformdescription model coupled with a platform independent model. To address these needs, we propose a model description formalism which takes into consideration these two aspects: dynamic structure modeling and system engineering. This formalism is based on DEVS and called Partially Reconfigurable Discrete Event System Specification (PRDEVS). PRDEVS allows to represent dynamic-structure models independently from the simulation platform. The presented approach can be applied to different types of targets, such as software and reconfigurable hardware. This thesis addresses these two kinds of platforms, demonstrating the suitability of the abstract formalism to actual platforms

Full textIn the context of intense international competition, many manufacturing firms are directing their investments toward African markets to increase their market share and maintain their competitiveness in the global market. These markets are rapidly growing but require customized products. Despite their attractivity, trade flows in Africa remain low due to the poor quality of infrastructure and the lack of regional logistic ecosystems, connecting African countries through reliable and efficient services.This doctoral thesis therefore focuses on modelling and solving the problem of designing hybrid distribution networks in Africa, integrating distribution and final customization platforms. These networks incorporate, upstream, regional hubs that serve as gateways to regional markets. The postponement of final customization downstream of the logistics network reduces the delivery times and downstream distribution costs while maintaining upstream economies of scale.The methodology we suggest is based on two main areas of research:▪ The first axis aims to define the location of regional logistics hubs, based on a fuzzy multi-criteria analysis approach, which is an improved version of TOPSIS fuzzy and AHP;▪ The second axis focuses on the design of hybrid distribution networks serving highly diversified markets in Africa (for example: fertilizer markets). To this aim, we propose two new multi-objective optimization models minimizing total operating and investment costs, maximizing product proximity to markets and minimizing damage to finished products during their distribution. The first model is deterministic while the second one proposes a flexible design in response to the dynamics and uncertainty of the evolution of African markets

Full textThe expansion and democratization of the digital world coupled with the effect of the Internet globalization, has allowed individuals, countries, states and companies to interconnect and interact at incidence levels never previously imagined. Cybercrime, in turn, is unfortunately one the negative aspects of this rapid global interconnection expansion. We often find malicious individuals and/or groups aiming to undermine the integrity of Information Systems for either financial gain or to serve a cause. The consequences of an intrusion can be problematic for the existence of a company or an organization. The impacts are synonymous with financial loss, brand image degradation and lack of seriousness. The detection of an intrusion is not an end in itself, the reduction of the delta detection-reaction has become a priority. The different existing solutions prove to be cumbersome to set up. Research has identified more efficient data mining methods, but integration into an information system remains difficult. Capturing and converting protected resource data does not allow detection within acceptable time frames. Our contribution helps to detect intrusions. Protect us against Firewall events which reduces the need for computing power while limiting the knowledge of the information system by intrusion detectors. We propose an approach taking into account the technical aspects by the use of a hybrid method of data mining but also the functional aspects. The addition of these two aspects is grouped into four phases. The first phase is to visualize and identify network activities. The second phase concerns the detection of abnormal activities using data mining methods on the source of the flow but also on the targeted assets. The third and fourth phases use the results of a risk analysis and a safety verification technique to prioritize the actions to be carried out. All these points give a general vision on the hygiene of the information system but also a direction on monitoring and corrections to be made.The approach developed to a prototype named D113. This prototype, tested on a platform of experimentation in two architectures of different size made it possible to validate our orientations and approaches. The results obtained are positive but perfectible. Prospects have been defined in this direction

Full textExtreme events are phenomena, often considered as catastrophic, that occur in the tail of a distribution usually deviating from an expected, exponential decay. In optics, these events were first studied in the context of fibers, where they have been extensively analyzed, as optical rogue waves, in light of the well known analogy between optics and hydrodynamics, through the nonlinear Schroedinger equation. With the development and the broadening of the field, extreme events have been also studied in dissipative optical systems with or without spatial degrees of freedom. In this Thesis we focused on the study of extreme events in three different active and dissipative optical systems, each presenting one or two spatial degrees of freedom, either in the transverse plane, perpendicular to the direction of propagation of light, or in the propagation direction. Localized structures of different nature represent an important possible solution in each one of the systems here studied, hence their interaction and the role played in the formation of extreme events have been also investigated into details. In the first system, a monolithic broad-area semiconductor laser (VCSEL) with an intracavity saturable absorber, we report on the occurrence of extreme events in the 2D transverse plane of the electric field intensity. In particular we highlight the connection between these objects and cavity solitons, both stationary and oscillatory, also present in the system. In the second system, a highly multimode laser with optical injection spatially extended along the propagation direction, we analyze the interaction and merging of phase solitons, localized structures propagating along the cavity carrying a 2π phase rotation. Extreme events have been investigated in two configurations: a first one where they emerge from the collision of phase solitons with other transient structures carrying a negative chiral charge, and a second one where high-peak events emerge from an unstable roll regime where phase solitons are not a stable solution. In both these systems we investigate the role of chirality in the extreme event formation. In the third system, a broad-area semiconductor laser (VCSEL) with optical injection, we study into details the interaction of cavity solitons in the transverse plane, described as two particles subjected to an interaction potential exponentially decreasing with the distance between the two objects: a possible analogy with hydrophobic materials is here suggested. Some preliminary results showing spatiotemporal extreme events in this system are also given
