Full textIn response to competition and new industrial challenges, companies are forced to be more and more efficient, productive and competitive. Managing industrial know-how and the data flow of the manufacturing digital chain must be explored in order to shorten the industrialisation time while ensuring better quality.In this context, this thesis focuses on digital chain data exploration for the capture of good practices in NC machining using a feature-based approach. Several issues related to machining feature characterisation and digital chain data exploitation for machining process knowledge reuse have been identified.To address these issues, a new characterization of multi-level complex machining feature has been proposed. The proposed approach is characterized by a hierarchical structuring of digital chain data and a mapping between the geometrical and machining data. A statistical analysis is then carried out to analyse and exploit this data. Curvature-based segmentation and statistical clustering of machining data were combined to define new machining regions based technological segmentation approach. These regions were then used to characterize the machining feature and thus ensure the reuse of machining data through a feature based and a region based approach exploiting similarity measures a similarity measure. Finally, the developed approach was applied on an industrial case in aeronautics

Wagner, Magali. "Impact des traitements hydrothermiques sur les propriétés techno-fonctionnelles de produits céréaliers." Thesis, Montpellier, SupAgro, 2010. http://www.theses.fr/2010NSAM0028/document.
Full textThe impact of hydrothermal treatments in addition to those of traditional process of pasta manufacturing has been studied to define the relationship "process / structure / properties". Pasta exclusively based on durum wheat semolina and other enriched in protein, amylose and lipids, were produced and then steamed for different time-temperature values, then boiled or sterilized. The structural characteristics of pasta were studied at different scales after each step of the process to determine the influence of unit operations and their parameters. The steam treatments mostly induce a loss of the crystal structure of native starch and the formation of complexes amylose-lipids with increasing temperature and moisture content of pasta. Moreover, the protein network was enhanced by cross-linking as much as temperature and duration of treatment increased. Theses structural changes are synthesized in a states diagram. When the pasta is heated in an excess of water, the protein network can be disrupted, complexes may disappear and amylopectine retrograde. The measurement of the rheological properties of these products have helped to assign the contribution of the mechanism of plasticization by water and of the presence of these structures. These latter mechanically reinforce the pasta and the additions of various ingredients may then improve their properties. based on these overall results, a diagram of the process has been proposed and its application with an appropriate formulation could allow to meet the technical objective of this work

Full textRheo-optic is a recent technique which can be used to create links between rheological properties and meso/microsctructures of model or complex (food) systems. A novel rheo-optical shearing device was designed for studying this relationships within complex food systems. The device has been build to be adapted on an inverted confocal microscope. Specifications of the shear cell are: a) a controlled translational shear between 2 parallel plates with three different motion modes (continuous, oscillatory, strain jump); b) a thermal control; and c) an observation on an inverted confocal microscope. Due to a vacuum system, the set up of an experiment is easy and fast ensuring reproducible optical properties (planarity, parallelism). Temperature, responsible of numerous modifications of structures in a food matrix, is also controlled. A piloting software allows an easy use of the shear cell. Validation of the motion modes has been carried out using a microgel, containing fluorescent probes (spheres) and tracking some of the particles. Next, in order to test and develop methods of observation under shear, taking into account the optical-mechanical balance, bread dough observation has been performed. Well known and described in the lab, bread dough is a dispersion of air bubbles and starch granules in a gluten network. Evolution on this gluten network depending on the formulation of the bread dough has been studied under oscillatory shearing. The composition effect on the microstructure and its evolution were observed and will be commented. Image analysis based on grayscale mathematical morphology has been carried out in order to try to quantify the rheological properties and microstructures. Finally, by a controlled increase of temperature, the growth of an air bubble in bread dough containing yeast was followed during proofing. The influence and the disposition of fat globules at the bubble air-protein interface along this growing process were followed. Thanks to the rheo-optical device, images of microstructures obtained under controlled shear are compared to their rheological behaviour

Full textThe goal of this thesis was the mutagenicity and genotoxicity assessment of whole exhausts issued from diesel engine together with the impact of new biodiesel fuels supplemented with rapeseed methyl ester (rmc) and the impact of aftertreatment devices (diesel oxidation catalyst and particulate filter). An original exposure device was used on various biological models, exposed directly under a continuous flow of exhaust (on line exposure), and compared with more classical exposure to resuspended particles (off line exposure) in liquid phase. On line exposure device is thought to be more realistic. This on line exposure model provides an innovative tool for the study of genotoxicity and mutagenicity of diesel exhausts, underlining the significant contribution of the gaseous phase. In contrast, particles implication seems to be by far more limited. Aftertreatment devices induce a very significant reduction of mutagenic and genotoxic effects of the particulate matter. On line protocol showed a limited but significant remaining genotoxicity and mutagenicity associated with the gaseous phase. Concerning biofuels, particulate matter is more genotoxic and mutagenic than that issued from standard gasoil. However, on line exposure to the whole aerosol reveals the lower pro-oxidant potential of biofuels. In all cases, the differences between fuels are dramatically reduced, or abolished, by the aftertreatment devices

Full textThe study of complex traits is of central importance in various fields, including evolutionary biology, medicine, agriculture, etc. Understanding the genetic factors involved in controlling these traits can be of paramount significance. For example, most diseases-related traits are complex, and unraveling novel drug targets can lead to new and improved treatment methods. Similarly, in agriculture, the identification of genetic loci associated with traits of interest, such as yield, adaptability, and resistance, can help improve crop productivity and quality. The genetic variation present at the population level can greatly contribute to the variance in phenotypic traits. In this thesis, we study the population-level variation in more than 200 complex traits in a natural Saccharomyces cerevisiae collection comprising of 1,011 strains. The study can be divided into three main parts. In the first part, we describe the global correlation patterns among all 223 phenotypes, highlighting some unexpected correlations between unrelated phenotypes. Furthermore, we quantified the correlation between the genetic and phenotypic distances of the strains and its variations between the different clades. In the second part, we identify genetic markers associated with the 223 phenotypes using genome-wide association studies (GWAS). Moreover, we confirmed that the patterns observed at the phenome level of the population were reflected at the genomic level, with a higher number of significantly associated genetic variants being shared between the more correlated phenotypes and vice versa. Finally, the last part is focused on predicting the phenome from various genomic and phenomic data. We developed a machine learning pipeline (GenPhen) that implements the automatization of the hyperparameters optimization process during model learning to obtain the most optimized model for individual phenotypes. In addition, the pipeline can be used to implement four ML methods capable of learning linear to highly non-linear models. We provide a comparison of the ability of the different ML models to predict phenotypes and also different kinds of input predictors including the pangenome, Single Nucleotide Polymorphisms (SNPs), transcriptomic, proteomics, etc. Finally, we implemented multitarget machine learning models that can predict the entire phenome with overall accuracy comparable to that of individual phenotype predictions. Overall, we showed that predictions vary highly depending on the phenotype and that most of the traits were highly polygenic, i.e., they are controlled by a large number of genetic factors with very small effects. In general, our study provides insight into the usefulness of different machine learning methods for predicting complex phenotypes, comparison of different types of predictors for the prioritization of the experimental data required for predictions, and interpretation of ML models to understand the underlying biological mechanisms controlling a trait

Full textCoupling wet air oxidation (WAO) and biological treatment has been studied to treat (industrial) wastewater containing glyphosate, a most widely used herbicide in the world. In order to evaluate the performance of the combined process, the performance of the individual WAO process and biological process to treat glyphosate-containing wastewater have been investigated. First of all, some experiments have been conducted to evaluate bubble hydrodynamic in a bubble column under WAO conditions in order to predict mass transfer and scale-up WAO process. Secondly, a kinetic study has been done to determine the kinetic parameters of glyphosate oxidation by WAO process and a possible oxidation pathway has been proposed. As well, a microfluidic device was used for WAO process to continuously treat glyphosate-containing wastewater in a compact and efficient process. Furthermore, in order to improve the glyphosate biodegradation by activated sludge, an acclimation process has been studies and glyphosate biodegradation kinetics by acclimated activated sludge have been investigated, as well as its possible biodegradation pathway. Finally, the pre-oxidized effluent was further treated by the acclimated activated sludge in order to conclude on the feasibility of the coupled process

Full textThe current thesis aimed at investigating verbal skills in individuals with ASD, focusing in particular on the impact of treatment on the development of these skills, as well as attempting to contribute to a more complete behavior analytic explanation of complex generative language.Our first study aimed at comparing the effect of behavioral treatment and multi disciplinary treatment on the verbal skills of children on the autism spectrum in natural settings. Treatment outcome was assessed by analyzing the results to standardized tests evaluating common vocabulary, spatial vocabulary, syntax and non-verbal reasoning and by comparing the number of children who had been mainstreamed into regular classrooms without the help of an aide. Participants with the best test scores on the standardized tests and whose learning rates reached or exceeded normal learning rates of language skills belonged to the group that received early intensive behavioral treatment. It is also in this group that we find the highest percentage of participants who were mainstreamed without special support. We also set to explore how child variables could influence treatment outcome. Our results indicated that age of intake had an effect only on the learning rates of verbal skills and that only for participants who received intensive behavioral treatment. In addition, we explored the possibility of a relation between the severity of symptoms at the age of 4-5 years and the learning rates and the severity of symptoms after approximately 4 years of intensive behavioral treatment. Data analysis revealed that severity of symptoms impairing the development and interfering communication at the age of 4 to 5 years were predictive of the severity of the symptoms that would be observed a few years later. We also conducted a follow up and compared the learning rates after on average of 2 years of intensive behavioral treatment and after on average 4 years of treatment. Significant variability was observed in the evolution in learning rates from one participant to another. Finally, in an attempt to better understand this heterogeneity, we studied the rate of skill acquisition over a 4-year period of children on the autism spectrum who received intensive behavioral treatment. The analysis of the learning curves indicated that there were two types of learners, fast learners and slow learners and that, regardless of age of onset of treatment.Our comparative study showed that whilst intensive behavioral treatment resulted in more important gains in the verbal skills of children with ASD than multi disciplinary treatment, all verbal skills were not affected in the same way. Indeed the gains in vocabulary were more important than the ones in grammar. We thus set in the second part of this thesis to conduct a behavioral analysis of the development of complex verbal skills in the typically developing population but also in the population on the autism spectrum. We used minimal verbal instructions, and matching to sample and sequence training procedures to develop responding to stimulus classes. These were considered analogous to complex verbal skills, namely syntactic relations and classes of verbs, nouns or adjectives

Full textQuerying images by their contents is of increasing importance in many application domains. For this reason, many researches are conducted in the two fields: DBMS and pattern recognition. But, the majority of the existing systems do not offer any formal framework to integrate the techniques in the two fields for effective multi-criteria queries on images. However, having a formal framework is necessary if one intends to treat such types of image queries effectively. In this thesis, we present image data repository models that allow to formulate multi-criteria queries. Then, based on this model, we introduced a similarity-based algebra that enables to formulate similarity-based queries and multi-criteria queries effectively and presented properties of the operators. We also presented techniques for similarity-based query optimization. We then developed a prototype called EMIMS (Extended Medical Image Management System) to show that our proposals in practical applications

Full textThis dissertation deals with meaning construction of linguistic complex expressions, particularly with + adjective-noun ; conceptual composition. Its main goal is to build up a theoretic frame suitable for the analysis of semantic problems concerning grammatical polymorphy, lexical polysemy or even metonymy. Such a theoretic frame is mainly conceived on the basis of notions stemmed from langacker's cognitive grammar, but ideas and formulations from both formal semantics (predicate logic, situation semantics,. . . ) and generative lexicon (pustejovsky, franks. . . ) are also taken into account the work as a whole relies on the hypothesis that linguistic expressions are directly linked to the conceptualization devices used by a speaker-listener in order to construe and organize the conceptual space (i. E. The universe of interpretation). Such conceptualizations devices are specified and characterized at different levels of abstaction for example, syntactic forms are conceived as instructions which configure and characterize semantic categories on the basis of a very schematic informational content to carry out such a category characterization, this work examines in detail the internal organisation of predicate structures, particularly the assignment operation of an entity to a predicate role. Lexical forms are also conceived as instructions which configure and characterise entities in the conceptual space. Yet, they do not characterise schematic categories, but an undetermined amount of assumptions concerning the organization of informational content at different levels of specification. This work relies on the conceptualization devices to build up a formal pattern of the semantic composition process. Such a compositional process is conceived as a set of conceptualization operations working on several aspects of the combined entities in order to integrate them into a composite entity. Taking into account the theoretical pattern of semantic composition defined previously, the last part of the dissertation describes the conceptual construction of some adjective-noun expressions

Full textThe dramatic advancement of low-cost hardware technology, wireless communications, and digital electronics have fostered the development of multifunctional (wireless) Multimedia Sensor Networks (MSNs). Those latter are composed of interconnected devices able to ubiquitously sense multimedia content (video, image, audio, etc.) from the environment. Thanks to their interesting features, MSNs have gained increasing attention in recent years from both academic and industrial sectors and have been adopted in wide range of application domains (such as smart home, smart office, smart city, to mention a few). One of the advantages of adopting MSNs is the fact that data gathered from related sensors contains rich semantic information (in comparison with using solely scalar sensors) which allows to detect complex events and copes better with application domain requirements. However, modeling and detecting events in MSNs remain a difficult task to carry out because translating all gathered multimedia data into events is not straightforward and challenging.In this thesis, a full-fledged framework for processing complex events in MSNs is proposed to avoid hard-coded algorithms. The framework is called Complex Event Modeling and Detection (CEMiD) framework. Core components of the framework are:• MSSN-Onto: a newly proposed ontology for modeling MSNs,• CEMiD-Language: an original language for modeling multimedia sensor networks and events to be detected, and• GST-CEMiD: a semantic pipelining-based complex event processing engine.CEMiD framework helps users model their own sensor network infrastructure and events to be detected through CEMiD language. The detection engine of the framework takes all the model provided by users to initiate an event detection pipeline for extracting multimedia data feature, translating semantic information, and interpret into events automatically. Our framework is validated by means of prototyping and simulations. The results show that our framework can properly detect complex multimedia events in a high work-load scenario (with average detection latency for less than one second)

Full textRecognising complex predefined behaviours by the analysis of event flows (Complex Event Processing - CEP) alows to interpret and react to large quantities of data wich one would not be able to apprehend alone. In this Ph.D. thesis, we provide a general theoretical framework for CEP through a purely formal approach ensuring the possibility to check and analyse the recognition process. We define a language, the chronicle language, allowing the description of the complex behaviours to be recognised. We formalise the notion of chronicle recognition through a set semantics based on an arborescent representation of recognitions. In order to use this framework, we then develop two models of the recognition process. The first relies on coloured Petri nets and allows the validation of recognition principles including concurrency and modularity issues. The second model directly implements the mathematical formalism in a C++ library, chronicle recognition library (CRL), wich is avaible in open source. We use this implementation to fulfil two applications linked to the insertion of unmanned aircraft system inside air traffic in case of communication link breakdowns. This application allows, on the other hand, to check the consistency of the procedures currently followed in case of failures ; and, on the other hand, to complete these procedures with alarms in case of unavoidable situations caused by human errors. The second application oversees that the security procedures of an unmanned aircraft flying through controlled or uncontrolled airspace are correctly followed

Full textMany thermodynamic changes occur in reservoir rock when oil is produced. These changes enable scale formation on micrometric rock pores that can block them and impede/block oil extraction. Antiscale treatment efficiency depends on minimal inhibitor concentration and product release rate in fluids downhole. In this context, we have studied two encapsulation techniques allowing us to have a sustainable release system composed of an anionic polyelectrolyte as a model additive. The first formulation consists in formation of polyelectrolyte complexes nanoparticles. In this system, active ingredient release was stimulated through medium ionic strength modulation. Under basic conditions, release takes place in particles swelling/dissociation process; whereas, under acidic condition, particles precipitate and no release can be expected. The second system we have worked on is a diluted reverse (W/O) emulsion, in which dispersed aqueous droplets contain a model additive. These systems are stable and small additive percentage is released under mechanic strain

Such objects gives high realism in computed images but are difficult to use (in terms of storage space and computing time). A lot of works as been driven in this context. We first describe commonly used approach that is point sample rendering, geometrical mesh simplification and image-based rendering. We first propose different algorithms to extend image based methods to real-time rendering. We then describe a method to generate 4D textures producing image of a given 3D object from arbitrary viewpoint, independently of its geometrical complexity. Finally, we present an image interpolation method to map relief onto a given depth image or a low polygon count version of a complex object. This works intensively use latest GPU capabilities, allowing high quality and real-time rendering at same time

Full textPattern detection over streams of events is gaining more and more attention, especially in the field of eCommerce. Our industrial partner Cdiscount, which is one of the largest eCommerce companies in France, aims to use pattern detection for real-time customer behavior analysis. The main challenges to consider are efficiency and scalability, as the detection of customer behaviors must be achieved within a few seconds, while millions of unique customers visit the website every day,thus producing a large event stream. In this thesis, we present Auros, a system for large-scale an defficient pattern detection for eCommerce. It relies on a domain-specific language to define behavior patterns. Patterns are then compiled into deterministic finite automata, which are run on a BigData streaming platform. Our evaluation shows that our approach is efficient and scalable, and fits the requirements of Cdiscount

Full textThis thesis describes new tools specifically designed for the analysis of networks such as social, transportation, neuronal, protein, communication networks... These networks, along with the rapid expansion of electronic, IT and mobile technologies are increasingly monitored and measured. Adapted tools of analysis are therefore very much in demand, which need to be universal, powerful, and precise enough to be able to extract useful information from very different possibly large networks. To this end, a large community of researchers from various disciplines have concentrated their efforts on the analysis of graphs, well define mathematical tools modeling the interconnected structure of networks. Among all the considered directions of research, graph signal processing brings a new and promising vision : a signal is no longer defined on a regular n-dimensional topology, but on a particular topology defined by the graph. To apply these new ideas on the practical problems of network analysis paves the way to an analysis firmly rooted in signal processing theory. It is precisely this frontier between signal processing and network science that we explore throughout this thesis, as shown by two of its major contributions. Firstly, a multiscale version of community detection in networks is proposed, based on the recent definition of graph wavelets. Then, a network-adapted bootstrap method is introduced, that enables statistical estimation based on carefully designed graph resampling schemes

The first and the second experiences aim at identifying the cues and the strategies of processing in language of rich morphology (Moroccan Arabic and classical Arabic) and at determining the type of transference which exist between them in view of their genetic paternity and their mode of appropriatness. The third experience. Led with French natives and bilingual Moroccans, has for aim to determine the strategies of processing of each group, to know the type of gestion applied to agrammatical sentences and to precise the nature of the dominant transference in this group "trilingual". In conclusion, we have suggested that the locality and the cost of processing must be in harmony with the characteristics of the language and that the socio-cultural factors influence the processing of language of languages in bilinguals

Full textTextiles are omnipresent in our everyday life. Research in this area tends to elaborate more sophisticated or "clever" materials i.e. confer new properties by means of innovative protocols. Among the available protocols, we can propose the grafting of microcapsules or host molecules able to guest an active substance which can be evolved. In our study, we synthesized original cyclodextrins bearing functional groups that allow their grafting on activated cotton fabrics. These entities maintain their inclusion ability. For activation purpose, we chose an "ecofriend" technology which does not require solvents, the corona discharge treatment (CDT). We evidenced that formation of free radicals, oxidation, and increase of roughness occur at the surface of cellulose during treatment. By carrying out experiments based on chemical activation, we concluded that free radicals are implied in grafting mechanism of allyl molecules and especially tetradecakis-(2,6-di-O-allyl)-β-cyclodextrin. Analysis by gravimetry, X ray photoelectron spectroscopy, thermogravimetry and scanning electon microscopy give the proof that grafting was effective. The inclusion ability of the modified β-cyclodextrins after grafting was studied with the dye extinction method determined by inclusion of phenolphthalein

Full textUsages of the internet of things experience an exponential growth these last few years. As a matter of fact, this is the result of, on one hand the significantly lowercosts in embedded computing systems, on the other hand the maturing of the software layers. From protocols and networks (CoAP, IPv6, etc) to standardization of ATMEL microcontrollers, tools at hand allow a better communication between more and more various sensors. This diversification gather every day users with different needs, expectations and fields of expertise, each one of them having his own approch, his own understanding of the connected things. The main issue concerns the complexity of the sensor networks, with regard to this necessity to address deeply different usages. Based on a single heterogeneous sensor network, it is critical to be able to meet the needs of each user, without having them to master the network beyond their own field of expertise. The tool described in this document aims at addressing this issue via a query engine dedicated to the processing of data collected from the sensors. Towards this end, it relies on a modelling of the sensors within several contexts, each of them reflecting a specific usage. On this basis a domain-specific language is provided, allowing complex event processing over the data monitored by the sensors. Furthermore, the implementation of this tool allows to interact with optional actuation functionalities of the sensor network

Full textSince the completion of the Human Genome Project in 2001, the field of genomicshas grown exponentially, in large part due to the introduction of Next GenerationSequencing (NGS). This technique has revolutionized the investigation methods ofgenetic diseases, allowing high-throughput genome-wide sequencing to establish thegenetic basis of diseases. The increasing accessibility of these technologies allowsthe development of precision medicine, based on the specific care of each patientaccording to his genetic profile. Sequencing can be used for the diagnosis ofdiseases, the search for genetic predispositions to a disease, or for the therapeuticchoice, in particular in oncology. Exome sequencing (WES), in particular, offers aneffective method for studying diseases, since exonic regions represent 2% of theentire genome, but can contain up to 85% of functional variants responsible fordiseases. However, the genetic analysis of patients in a clinical setting is mainly carried out by the targeted sequencing of panels of a few genes chosen according tothe clinical context. The work carried out during this CIFRE thesis in partnership withthe company Prenostics was to develop relevant WES analyzes to characterize thegenetic profile of patients with rare genetic diseases and cancers. The objective wasto assess their contribution to the diagnosis and establishment of personalizedtreatment strategies in three distinct contexts of clinical practice, by comparing it tothe conventional approach of panel sequencing.- In the field of pediatric genetic diseases, molecular diagnosis by conventionalmethods only reaches 25%, leaving the majority of families without precise geneticcounseling. Our WES analysis of a cohort of 26 children with genetic diseases notdiagnosed by conventional genetic analyzes, our WES approach resulted in apositive diagnosis in 35% of cases.- About 5 to 10% of breast cancers are hereditary, but more than half of them are notelucidated by the genes at risk of breast cancer (BRCA1, BRCA2, PALB2, etc.) thatare included in conventional panel sequencing. By analyzing the exome of fourfamilies, we attempted to identify the genes involved in familial cases non-mutatedfor the known BRCA1 / BRCA2 genes (BRCAx families). After filtering the riskvariants transmitted among affected limbs, we identified the candidate genesHIST1H1C, TYRO3, TPH1, SLC12A3 and CCNF as possible genes of predispositionto breast cancer. However, without in-depth functional studies to validate theirinvolvement, WES does not seem to provide any benefit for patient management.- Finally, in the field of oncology, the personalization of treatment is at the center ofcurrent issues. Our study of a cohort of 35 refractory solid tumors aimed atdemonstrating the feasibility and efficacy of WES for characterizing the geneticprofile of solid tumors and for decision-making in oncology. We were able to maketreatment suggestions for half of them and helped modify the treatment of at leasteight out of 35 patients.This study describes the different applications, limits and advantages of WES as amolecular investigation tool for human diseases. By demonstrating the benefit ofusing WES in the clinic, our results contribute to the ongoing efforts to integrate it intothe care pathway and the development of precision medicine
