Abstract:
Automatic classification of devices in computer network can be used for detection of anomalies in a network and also it enables application of security policies per device type. The key to creating a device classifier is a quality data set, the public availability of which is low and the creation of a new data set is difficult. The aim of this work is to create a tool, that will enable automated annotation of the data set of network devices and to create a classifier of network devices that uses only basic data from network flows. The result of this work is a modular tool providing automated annotation of network devices using system ADiCT of Cesnet's association, search engines Shodan and Censys, information from PassiveDNS, TOR, WhoIs, geolocation database and information from blacklists. Based on the annotated data set are created several classifiers that classify network devices according to the services they use. The results of the work not only significantly simplify the process of creating new data sets of network devices, but also show a non-invasive approach to the classification of network devices.

Abstract:
This thesis investigates the grammatical constructions of be-and get-passives and their usage by Swedes writing in English. The investigation is based on findings from four different corpora, two of which were compiled for the purpose of this study. The first one, SWENC (the Swedish English Newspaper Corpus), contains texts from online newspapers and a corporate newsletter written by Swedes in English. The second, BESC (Blogs in English by Swedes Corpus), contains material collected from blogs written in English by Swedes. The results from these corpora are compared with results from the press sub-corpora of the native English Frown (American English) and F-LOB corpora (British English). The results show that Swedes writing in English use passive constructions to a similar extent as native English speakers do within the news genre. Furthermore, Swedes writing in English use significantly more be-passive constructions within the news genre than the more informal blog genre. Lastly, the study shows that Swedes writing in English use get-passives, and that they are considerably more common in the informal language used in blogs than the more formal language used in online newspapers.

Abstract:
Les suspensions magnétiques permettent la lévitation d'un corps sans contact. Un mobile peut ainsi être déplacé à grande vitesse sans engendrer de frottement ni d'usure. Les applications de ces systèmes sont essentiellement circulaires (turbines, volant d'inertie, centrifugeuse, machine outils. . . ) mais peuvent ainsi être linéaires (train. . . ). Les suspensions magnétiques sont déjà utilisées dans l'industrie mais leur prix de revient, dû à l'asservissement de tous les degrés de liberté de la partie suspendue, freine leur expansion. L'étude porte sur les suspensions magnétiques dont une partie des degrés de liberté est contrôlé par des paliers autonomes à aimants permanents. Les associations de paliers permettant de réaliser une suspension sont décrites ainsi que les motorisations possibles et les systèmes d'amortissement. La réalisation d'un prototype a mis en évidence les avantages et les inconvénients d'une suspension ne possédant qu'un seul axe asservi

Abstract:
Aquesta tesi és el resultat de la primera investigació extensa en l’adquisició de les passives agentives en dues varietats de català: el català central i el mallorquí. L’adquisició de passives per part dels nens mostra un retard en diverses llengües, especialment aquelles en què la passiva verbal i l’adjectiva no són homòfones. En primer lloc presento un estudi de dades espontànies tant en adults com en nens per veure la freqüència dels diferents tipus de passives (perifràstica, adjectiva i pronominal) en català. Mitjançant una tasca d’aparellament d’imatges i frases vaig realitzar un primer experiment per esbrinar l’adquisició de passives agentives en català. Com que en català mallorquí s’utilitza la mateixa preposició en les passives llargues i en els nominals agentius vaig fer un segon experiment per veure la possible facilitació en la comprensió de les formes passives llargues en tenir la mateixa preposició. La preposició però, no va tenir cap efecte en els resultats. Finalment, un tercer experiment compara la comprensió de les passives adjectives i les passives curtes. Els resultats indiquen que fins als 7 anys els nens fan una interpretació adjectiva de les passives verbals.
This thesis results from the first comprehensive investigation into children’s acquisition of actional passives in two varieties of Catalan: Central Catalan and Majorcan Catalan. The acquisition of passives by children has proved to be delayed in a number of languages, especially those which do not have s-homophones between an adjectival passive and a verbal passive. Firstly, a study of spontaneous production in children and adults was made to see the frequency of the different kinds of passives (periphrastic, adjectival and pronominal) for both groups. Using a sentence-picture matching task I undertook a first experiment to see if there was delay in the acquisition of actional passives in Catalan. Also, and because the by-phrase in Majorcan Catalan has the same preposition as agentive nominals, a second experiment was run to see the possible facilitation of having the same preposition in the comprehension of long passive constructions; no effect of the preposition was found. Lastly, a third experiment was run to check the comprehension of adjectival passives versus short passives; verbal passives were shown to be interpreted as adjectival until the age of 7.

Abstract:
The demand for high power density keeps driving the development of electromagnetic integration technologies in the field of power electronics. Based on planar homogeneous integrated structures, the mechanism of the electromagnetic integration of passives has been investigated with distributed-parameter models. High order modeling of integrated passives has been developed to investigate the electromagnetic performance. The design algorithm combining electromagnetic design and loss models has been developed to optimize and evaluate the spiral winding structure. High power density of 480 W/in3 has been obtained on the prototype. Due to the structural limitation, the currently applied planar spiral winding structure does not sufficiently utilize the space, and the structure is mechanically vulnerable. The improvement on structures is necessary for further application of integrated passives. The goal of this research is to investigate and evaluate alternative structures for high-power-density integrated passives. The research covers electromagnetic modeling, constructional study, design algorithm, loss modeling, thermal management and implementation technology The symmetric single layer structure and the stacked structure are proposed to overcome the disadvantages of the currently applied planar spiral winding structure. Because of the potential of high power density and low power loss, the stacked structure is selected for further research. The structural characteristics and the processing technologies are addressed. By taking an integrated LLCT module as the study case, the general design algorithm is developed to find out a set of feasible designs. The obtained design maps are used to evaluate the constraints from spatial, materials and processing technologies for the stacked structure. Based on the assumption of one-dimensional magnetic filed on the cross-section and linear current distribution along the longitudinal direction of the stacked structure, the electromagnetic field distribution is analyzed and the loss modeling is made. The experimental method is proposed to measure the loss and to verify the calculation. The power loss in the module leads to thermal issues, which limit the processed power of power electronics modules and thus limit the power density. To further improve the power handling ability of the module, the thermal management is made based on loss estimation. The heat extraction technology is developed to improve the heat removal ability and further improve the power density of integrated passives. The experimental results verify the power density improvement from the proposed stacked structure and the applied heat extraction technology. The power density of 1147 W/in3 (70 W/cm3) is achieved in the implemented LLCT module with the efficiency of 97.8% at output power of 1008W.

Abstract:
En chinois contemporain, la forme passive standard est la suivante : "(sni) + bei (+ sn2-agent) + v (+ c)". Cette structure est attestee des le chinois medieval, au viiie siecle, mais elle devient la forme passive la plus courante seulement en chinois moderne, aux alentours des xive et xve siecles. Auparavant, en chinois archaique et en chinois medieval, d'autres constructions mettant en jeu d'autres marqueurs que bei sont utilisees pour l'expression du passif. Ce sont, pour l'essentiel, les formes en yu, les formes en wei. . . Suo, les formes en jian. Les diverses contraintes des formes passives aux niveaux syntaxique, semantique et communicatif expliquent pourquoi les formes actives n'ont pas toujours une forme passive correspondante et pourquoi certaines formes passives s'averent aller plus naturellement de soi que leurs formes correspondantes actives. Les differences degagees entre le chinois et le francais expliquent aussi pourquoi certaines passives sont obligatoirement interpretees par des formes actives dans l'autre langue, et pourquoi un choix s'impose toujours entre les degres syntaxique, semantique ou communicatif
In today's chinese, the common passive form is the following : "(np1) + bei (+ np2-agent) + v (+c)". This structure can already be found in medieval chinese (8th century a. D. ), but it only became the most current passive form in modern chinese, around the 14th and 15th centuries. In archaic chinese and in medieval chinese, other constructions with other marks than bei were used to express the passive form. They were essentially : i. E. Yu, wei. . . Suo and jian. Various constraints on the passive forms regarding syntax, semantics and communication as well, explain why all the active forms may not always have an exact corresponding passive form and why some passive forms are sometimes more natural than their corresponding active forms. The differences that arise between the chinese language and the french language, emphasize the fact that some passive forms in one language are adequately rendered by active forms in the other language, thus a choice has to be made between syntaxic, semantic and communicative levels

Abstract:
Multilayer embedded passives (resistors, inductors, and capacitors) on a printed wiring board can help to meet high performance requirements at a low cost and at a smaller size. Such an integration of embedded passives has new challenges with respect to design, materials, manufacturing, thermal management and reliability. As the area of integral passives on printed circuit boards is relatively new, there is inadequate literature on the thermo-mechanical reliability of integral passives. Therefore, there is a compelling need to understand the thermo-mechanical reliability of integral passives through the development of physics-based models as well as through experiments, and this thesis aims to develop such an experimental and theoretical program to study the thermo-mechanical reliability of integral passives.. As integral passives are often composite layers with dissimilar material properties compared to the other layers in the integral substrate, it is essential to ensure that RLC characteristics of the embedded passives do not deteriorate with thermal cycling due to thermo-mechanical deformations. This thesis aims to study the changes in the passive characteristics due to the thermally-induced deformations. Embedded capacitors and inductors have been looked at specifically in this research. Multi-field physics-based models have been constructed to determine the change in electrical parameters after thermal cycling. The thermo-mechanical models assume direction-dependent material properties for the board substrate and interconnect copper layers and temperature-dependent properties for interlayer dielectric and passive layers. Using the deformed geometry, the electrical characteristics have been determined at low frequency. In parallel to the models, test vehicle substrates have been subjected to 1000 thermal cycles between -55??o 125??nd high humidity and temperature conditions at 85??5RH for 500 hours, and it has been observed that there are significant changes in the electrical parameters. The results obtained from the physics-based simulations have been validated against the measured electrical characteristics from the fabricated functional test boards that have been thermal cycled.

Abstract:
Les deux mesures hyperfrequences issues du radiometre et du radar-altimetre sont sensibles simultanement aux parametres de surface et d'atmosphere. Le but de ce travail est d'etudier la faisabilite du couplage de ces deux types de donnees en tenant compte de leurs interactions. Pour cela, un modele de diffusion-emission-transfert radiatif a d'abord ete valide dans le sens direct par comparaison avec des mesures reelles : temperatures de brillance et cfficients de retrodiffusion. Cette premiere etape a montre l'importance de mener un etalonnage coherent des deux types de mesures. La deuxieme partie du travail a consite a inverser le modele en vue de restituer les differents parametres geophysiques. L'inversion basee sur une methode physique iterative, est comparee avec d'une part des algorithmes statistiques utilises de maniere operationnelle et d'autre part avec des mesures bateaux et des radiosondages. Nous avons ensuite developpe une autre methode d'inversion couplee inspiree des techniques utilisees en radiometrie hyperfrequence, nettement plus performante en termes de temps de calcul. Une etude comparative a permis de mettre en evidence les avantages et les limitations des deux methodes d'inversion. De nombreuses combinaisons ont ete testees, prenant en compte tous ou une partie des canaux du radiometre hyperfrequence ainsi que la ou les mesures altimetriques. Ces tests ont ete effectues tant en iteratif qu'en statistique. Ils montrent l'interet du couplage des donnees hyperfrequences actives et passives. Les configurations instrumentales analysees ici sont celles de topex-poseidon et d'ers(1 et 2).

Full text
Abstract:
Les marges passives sont des structures lithosphériques intra-plaques, assurant la transition entre une croûte continentale non amincie et une croûte océanique. Du fait de leur position en bordure des continents, les marges passives sont soumises à des flux sédimentaires externes au système, produits par l'érosion de reliefs continentaux en amont de la marge, et elles sont affectées par une déformation complexe et de faible intensité qui intègre la déformation produite par les processus intrinsèques au système (ex : isostasie flexurale, subsidence thermique) mais aussi les déformations intra-plaques, et enfin les déformations en limite de plaque. Les bassins sédimentaires des marges passives en domaine marin et les données de dénudation en domaine continental enregistrent donc, de manière indépendante, des processus locaux, régionaux ou globaux. Jusqu'à présent, les études publiées sur les marges passives ont le plus souvent été segmentées entre, d'une part, les domaines non aminci et de transition, et d'autre part, le domaine aminci des marges passives. Pour approfondir nos connaissances sur le comportement et l'enregistrement post-rift des marges passives, nous avons réalisé, à l'aide d'un nouveau modèle numérique 3D couplant des processus thermiques, de l'isostasie flexurale et des processus de surface, une nouvelle étude intégrant la marge depuis le domaine continental non aminci jusqu'au domaine aminci
Passive margins are intra-plate lithospheric structures located at the transition between continental and oceanic crust. Because of their location on the border of continents, passive margins record sediment transfer, produced by erosion of continental relief far from the margins, and complex and low intensity deformations produced by intrinsic processes (eg, flexural isostasy, thermal subsidence), intra-plate deformations, and plate boundary deformation. The sedimentary accumulation in basins and the continental denudation result in local, regional, and global processes with complex coupling. Up to the present, published studies on passive margins have generally been segmented between, unstretched and transitional domains and stretched domain of passive margin. To improve our understanding of post-rift deformation and recording of passive margin, we have done a new study incorporating the margin since unstretched domain to stretched domain. We used in this study, a new 3D numerical model coupling thermal processes, the flexural isostasy and surface processes

ENGLISH ABSTRACT: This study focuses on the grammatical properties and syntactic derivation of KRY (“get”)-passives in Afrikaans. Analyses of the corresponding phenomenon in other West-Germanic languages are examined and used as background for the study. The aim of the study is to provide a minimalist analysis of the internal structure of Afrikaans KRY-passives; no such analysis has to date been attempted within the framework of Minimalist Syntax. As an introduction to the phenomenon in Afrikaans, some grammatical background about kry and its syntactic distribution is provided, with special attention paid to the use of this verb in passive constructions. A new analysis of Afrikaans KRY-passives is put forward involving a small clause structure and a light verb component. The main hypothesis of the analysis is that eventive and stative KRY-passives are derived in basically the same manner, the important difference being the presence of a [process] and a [stative] feature, respectively, on the small clause light verb. This hypothesis provides support for the idea that the eventual eventive or stative interpretation of the structure is a consequence of the derivational process rather than being based on lexical features that are already present at the start of the derivation.
AFRIKAANSE OPSOMMING: Hierdie studie fokus op die grammatikale eienskappe en sintaktiese afleiding van KRY-passiewe in Afrikaans. Analises van die ooreenstemmende verskynsel in ander Wes-Germaanse tale word ondersoek en as vertrekpunt vir die studie gebruik. Die doel van die studie is om ‟n minimalistiese analise van die interne struktuur van Afrikaanse KRY-passiewe te ontwikkel; so ‟n analise is nog nie tevore binne die raamwerk van Minimalistiese Sintaksis aangebied nie. As algemene inleiding tot die verskynsel in Afrikaans, word enkele aspekte van kry se grammatikale eienskappe en sintaktiese verspreiding beskryf, met besondere klem op die gebruik van hierdie werkwoord in passiefkonstruksies. ‟n Nuwe analise van KRY-passiewe in Afrikaans word voorgestel, een wat gebruik maak van ‟n beknopte sin (“small clause”)-struktuur en ‟n ligte werkwoord (“light verb”)-komponent. Die vernaamste hipotese van die analise is dat gebeurtenis (“eventive”) en toestand (oftewel statief, “stative”) KRY-passiewe wesenlik op dieselfde manier afgelei word, met een belangrike verskil, naamlik die teenwoordigheid van, onderskeidelik, ‟n [proses]- en ‟n [statief]-kenmerk by die beknopte sin se ligte werkwoord. Dié hipotese verleen steun aan die idee dat die uiteindelike gebeurtenis- of toestand-interpretasie van die struktuur die gevolg is van die afleidingsproses, en dus nie gebaseer is op leksikale kenmerke wat reeds teenwoordig is by die aanvang van die afleiding nie.

Abstract:
Une marge passive est une zone de transition non-active entre lithosphère continentale et lithosphère océanique. De nombreuses marges passives présentent un fort développement magmatique (>50%). Ces marges passives volcaniques (MPVs) marquent la rupture lithosphérique au-dessus d’un manteau en fusion (partielle) et sont typiquement caractérisées par l’intrusion et l’extrusion d’un volume significatif de produits magmatiques dans la croûte lors des périodes ante-rift, syn-rift et post-rift. A partir d’une compilation bibliographique, de données sismiques (profils de sismique réflexion ION-GXT, sismique 3D) et d’observations réalisées sur le terrain à l’Est et à l’Ouest du Groenland, les objectifs de cette thèse étaient : (1) de mieux caractériser les modes tectoniques d’accommodation des flexures de la croûte supérieure sous les SDRs (seaward dipping reflectors) et l’interprétation des SDRs externes et, (2), de placer la rupture magmatique à l’échelle de la fragmentation d’un supercontinent. Les principaux résultats obtenus sont: 1) La rupture d’un supercontinent est toujours synmagmatique. Cette rupture se propage ensuite de manière non-magmatique (article en préparation); 2) Les SDRs externes sont découplés tectoniquement d’une croûte inférieure d’origine continentale exhumée. Du matériel d’origine continental pourrait exister en profondeur de manière continue au niveau de rides asismiques transverses (comme GIFR) (article soumis); 3) La flexure crustale est aussi accommodée par du magma qui circule dans les failles de détachement sous SDRs. Un découplage existe à l’extrados des flexures accommodé par des injections de magma syn-tectoniques sous forme de laccolithes à la base des SDRs internes
A passive margin is a non-active transition zone between the continental lithosphere and the oceanic lithosphere. Most of passive margins (>50%) show a strong magmatic development. These volcanic passive margins (VPMs) mark the lithospheric breakup over a melted mantle and they are typically characterized by a huge volume of intrusive and extrusive magmatism into the crust during ante-rift, syn-rift, and post-rift periods.Based on bibliographies, seismic data (IONGXT seismic reflection profiles, 3D seismic) and observations and results gained from fieldtrips on East and West Greenland coast, the objectives of this thesis were: (1) to better characterize the tectonic accommodation of the flexure of the upper crust which beneath inner SDRs and the signification of outer SDRs, and (3) to place the magmatic breakup on the scale of the fragmentation of a supercontinent.The main results obtained are: 1) the breakup of a supercontinent is always syn-magmatic. This breakup then propagates in a non-magmatic way (paper in preparation); 2) the outer SDRs are tectonically decoupled from an exhumed continental lower crust.The material of continental origin could exist deeply continuously across a transverse aseismic ridge such as the GIFR (paper submitted); 3) The crustal flexure is also accommodated by the magma that circulate in detachment faults beneath the inner SDRs. There is a decoupling at the extrados zone of the flexure which is accommodated by syn-tectonic magma injections in the form of laccoliths between inner SDRs and upper crust

Full text
Abstract:
The main purpose of this thesis is to shed new light on Japanese grammar under the framework of the Givónian approach, with special attention to OSV word orders and by-passives: scrambling (OACCSV), topicalization (OTOPSV), ni-passive (S NPNI V), and niyotte-passive (S NPNiyotte V). This approach measures the discourse status of a referent by utilizing anaphoric and cataphoric co-referencing relationships within the texts. However, it is conceivable that OSV word orders and by-passives are also influenced by multiple factors other than information structure. Specifically, previous studies point out the possibility that heaviness and animacy are relevant to this issue. Therefore, the present study performs the corpus analysis, taking three factors into consideration: heaviness, animacy, and information structure. First, OSV word orders have proven to be influenced by information structure and heaviness. In terms of information structure, scrambling correlates 'topic shift' from the referent of the scrambled object to that of the subject. In contrast, topicalization interrelates with 'continuing topic' realized as the referent of the subject. In terms of heaviness, the direct object tends to be longer than the subject in OSV word orders. Yet, animacy has no influence on the choice of word orders. Second, by-passives are affected by information structure and animacy. In terms of information structure, the ni- and niyotte-passives are selected in order to maintain the topic continuity by promoting the topical logical object to the grammatical subject. However, the ni-passive is relevant to global topic whereas the niyotte-passive is related to local topic. In terms of animacy, the ni-passive prefers animate subjects while the niyotte-passive tends to select inanimate subjects. Yet, heaviness is unrelated to the use of by-passives in Japanese. In conclusion, the thesis provides a functional analysis of OSV orders and by-passives from a descriptive and empirical point of view by using a written Japanese corpus. The new data reported contribute to elucidating the argument encoding system of Japanese.

Full text
Abstract:
This paper proposes a diachronic and synchronic analysis of the extensive use of se in Spanish reflexive and passive constructions with se being discussed in relation to the Unaccusative Hypothesis in Arc Pair Grammar.Universals in Arc Pair Grammar, namely the Unaccusative Law, the 1-Advancement Exclusiveness Law and the Final 1-Arc Law will account for the similarities and differences, first between English and Spanish predicates; and second, between ordinary reflexive constructions and reflexive passive constructions.Evidence from Spanish, primarily synchronic, is presented to analyze reflexive constructions that come from an initial unaccusative stratum. A parallel between these constructions and reflexive passives is established to demonstrate that unaccusative predicates and reflexive passive constructions are very closely related.Diachronically the paper claims that there is a logical and clear evolution of se based on corefentiality, anaphoric chains, unspecified arguments, and self-erasing ghost arcs.Finally this paper attempts to explain why in some instances the predicate will not exhibit agreement with the corresponding nominal. The Chomeur relation and the introduction of ghost arcs according to Arc Pair Grammar Laws and Theorems will provide the basis for this explanation.

Abstract:
This doctoral dissertation reports on an empirical study, which takes a feature-based approach and probes the L2 acquisition and processing of Chinese bei passives by adult English native speakers. In Chinese, an individual passive marker bei is used to mark passive constructions. Whilst historically used as a lexical verb, bei is in the process of being grammaticalised (i.e. semi-lexical) and hence contains a semantic component (Liu, 2012a). Three forms of bei passives and their semantic properties have been investigated: basic long bei passives (i.e. with an external argument), basic short bei passives (i.e. without an external argument), and the retained-object construction of bei. In total, 75 English native speakers with intermediate and advanced Chinese proficiency, and 33 native Mandarin Chinese speakers (serving as a control group) were tested by a series of on-line methods (a self-paced reading task and a reaction-time picture elicited word rearrangement task) and off-line methods (an untimed acceptability judgement task and a fill-in-the-blank task). The current study finds that the reconfiguration of target semantic features of bei is a gradual process and occurs feature-by-feature, depending on consistent and ample input-based evidence. This lends support to the Feature Reassembly Hypothesis (Lardiere, 2005, 2008, 2009). It is also found that morphosyntax-semantics mismatches lead to acquisitional difficulties, as predicted by the Bottleneck Hypothesis (Slabakova, 2008, 2009b), which shares a similar view to the Feature Reassembly Hypothesis. In addition, L1 English L2 Chinese learners are found to be subject to the formation strategy of English short passives, in line with Montrul (2001). A disjunction in L2 performance between off-line and on-line tasks has been found in the advanced learners, who show target-like on-line sensitivity to violations of semantic constraints on bei but fail to converge on the target grammar in off-line judgements. These findings are compatible with Ullman's (2001, 2005) declarative-procedural model and suggest that the increase in convergence on real-time comprehension and production in the advanced learners is a result of the more involved procedural system. The general findings of the current study lend support to the view (Sorace, 2009; White, 2011) that representational and processing difficulties must be teased apart in L2 acquisition.

Ce travail présente une étude de guides d'onde de taille submicrométrique (GOTS) réalisés en filière InP, filière particulièrement adaptée aux composants actifs des télécommunications à 1,3æm et 1,55æm. L'intérêt de tels dispositifs à fort confinement optique se manifeste dans la miniaturisation des systèmes optoélectroniques. Plusieurs méthodes de gravure des GOTS ont été envisagées : humide, RIE et ICP ; ce qui, parallèlement à des simulations par BPM (beam propagation method) de la propagation dans des GOTS idéaux permettant de déterminer l'influence des différents paramètres technologiques sur les pertes de propagation, nous a permis de dégager une structure épitaxiale et une technologie préférentielles. L'analyse de ces différentes informations nous a permis de réaliser par gravure ICP des GOTS de 0,3æm de large au minimum, présentant des pertes du même ordre de grandeur que celles relevées dans la littérature pour des structures similaires réalisées en filière GaAs.

Abstract:
Ce travail a pour objectif de mettre au point un système d'échantillonnage pour les sources surfaciques passives (bassin de décantation, décharge) afin de mesurer l'émission d'odeur de ce type de source. En l'absence de méthode de référence, un pilote de laboratoire (tunnel à vent) a été conçu visant à simuler une source surfacique odorante soumise à l'action du vent. L'étude aérodynamique ainsi que celle du transfert de matière valident cet outil du fait de la justesse de l'émission vérifiée par le biais de bilans de matière et par la répétabilité satisfaisante des mesures de flux massiques et de facteurs de dilution. Parallèlement, une nouvelle définition du débit d'odeur de sources surfaciques passives a été proposée : elle prend en compte le débit de molécules odorantes transférées de la phase liquide vers la phase gazeuse et est, de ce fait, parfaitement adaptée aux cas spécifiques des sources surfaciques passives. L'évaluation de systèmes d'échantillonnage a porté, dans un premier temps, sur une chambre à flux dynamique construite selon les préconisations de la norme NF X 43-104. L'étude a mis en évidence les limites de cet outil tant du point de vue de l'exactitude que de la répétabilité des mesures de flux massiques. Une nouvelle chambre à flux a été élaborée et testée à la fois en laboratoire et sur le terrain. La bonne répétabilité et l'exactitude des mesures de flux massiques, facteurs de dilution et débit d'odeur obtenus à l'aide de la chambre ont été prouvées. A donc été mis au point un outil de terrain dont l'utilisation conduit à évaluer de manière fiable l'émission d'odeur de sources surfaciques passives.

Abstract:
The challenge to put power electronics on the same cost reduction spiral as integrated signal electronics has yet to be met. In the ongoing work for achieving complete power electronic converter integration, it has proven to be essential to develop a technology for integration of electromagnetic power passives. This integration will enable the incorporation of resonant circuits, transformers, EMI filters and the like into the integrated power electronics modules. These integrated electromagnetic power passives have been realized in terms of distributed structures, utilizing magnetic layers, conductive layers and dielectric layers. Because of the compact structures and the special implementation techniques of these integrated modules, the high frequency parasitic resonance are normally significant and may have negative impact on the performance and EMI characteristics. However, the existing modeling technique can only predict the fundamental resonant frequency and showed neither the causes of the high frequency resonance nor how to calculate those accurately. In this dissertation, comprehensive research work towards higher order electromagnetic modeling of integrated passive components is presented. Firstly, an L-C cell is identified as the basic building block of integrated passives such as an integrated series resonator. As an essential mistake in the structure evolution process of the original resonant transmission line primitive, the well-known conventional transmission line equivalent circuit as well as the equations are not applicable for the unbalanced current in an integrated passive module. For this particular application, a generalized transmission structure theory that applies to both balanced and unbalanced current has to be developed. The impedances of a generalized transmission structure with various loads and interconnections have been studied. An open-circuited load and a short-circuited load lead to series resonance and parallel resonance, respectively. The equations are substantiated with experimental results. Some preliminary study indicates the advantages of this unbalanced current passives integration technique. Since the existing integrated passive components are no other than some combination of this generalized transmission line primitive, the theoretical analysis may be applied to the further modeling of all integrated passive components. As the extension of the generalized two-conductor transmission structure model developed for the two-conductor approach, the generalized multi-conductor transmission structure theory has been proposed. As multiple L-C cells are putting in parallel, magnetic and capacitive coupling between cells cannot be neglected. To determine the capacitance between two adjacent conductors on top of the same dielectric substrate, Schwarz-Christoffel transformation and its inverse transformation have been applied with the calculation results verified by measurement. Based on the original voltage and current equations written in matrix form, modal analysis has been conducted to solve the equations. All these provide the basis for any further modeling of an integrated passive structure. Based on the basic L-C cell structure, this dissertation proposes an alternative multi-cell approach to the integration of reactive components and establishes the principles for its design and operation. It achieves the 3-D integration and has a PCB-mount chip-like structure which may have the potential to be more manufacturable, modularizable and mechanically robust. Different functional equivalents can be obtained by different PCB interconnections. The experimental results confirm the functionality as integrated reactive components for applications such as high frequency resonators. To apply the multi-conductor generalized transmission structure model to practical integrated passives structures, three typical cases have been studied: spiral-winding structure integrated series resonator, multi-cell structure integrated series resonator and integrated RF EMI filter. All these structures can be treated as one or more multi-conductor transmission structures connected in certain patterns. Different connection patterns only determine the voltage and current boundary conditions with which the equations can be solved. After obtaining the voltages and currents at each point, the impedance or transfer gain of a structure can be obtained. The MATLAB calculation results correlate well with the measurement results. The calculation sensitivities with respect to variation of various parameters are also discussed and causes of resonance at different frequency range are identified. The proposed generalized transmission structure model based on matrix modal analysis is rather complex and takes a lot of computer time especially when the number of turns is large. Furthermore, the operating frequency of an integrated resonant module is normally around its 1st resonant frequency and up to the 2nd resonant frequency. Therefore, a more simplistic higher order lumped element model which covers the operating range up to the 2nd resonant frequency may be good enough for the general design purpose. A higher order equivalent circuit model for integrated series resonant modules as an example of integrated power passives is presented in this dissertation. Inter-winding capacitance is also considered compared to the conventional 1st order approximation model. This model has been verified by small-signal test results and can be easily implemented into the design algorithm as part of the high frequency design considerations. The wide band modeling and proposed new structure mentioned above provide a comprehensive basis for better design of integrated passive components. As a general frequency plane modeling approach, the work presented in this dissertation may be extended to other passive structures, such as multi-layer capacitors, planar magnetics, etc..

Abstract:
The 21st century will be the information age characterized by an ever-increasing need for advanced communication systems. To reach such target, the demand for more complexity and higher performance leads to new generations of fast and accurate passive models. This thesis addresses an important aspect of high-frequency Computer Aided Design (CAD), i.e., the modeling of passive devices and interconnects in the RF/microwave frequency range where high-order electromagnetic (EM) effects are quite significant. The main objective of this thesis is the EM circuit optimization and design based on neural models. To achieve this goal efficiently, different external codes for automated data generation for neural model training of passive components and interconnects has been developed. A CAD tool for circuit topology optimization using neural models of interconnects and passives have been also introduced. It allows automatic adjustment of component and connection geometry and then provides fast estimation of overall circuit performance. A technique for including mutual coupling effects between passives in circuit design has also been proposed. It allows the usage of individual neural models in a circuit level design and optimization, providing fast estimation of the EM effects with respect to the different connecting positions.

Abstract:
In a typical printed circuit board assembly, over 70 percent of the electronic components are passives such as resistors, inductors, and capacitors, and these passives could take up to 50 percent of the entire printed circuit board area. By embedding the passive components within the substrate instead of being mounted on the surface, the embedded passives could reduce the system real estate, eliminate the need for surface-mounted discrete components, eliminate lead based interconnects, enhance electrical performance and reliability, and potentially reduce the overall cost. Even with these advantages, embedded passive technology, especially for organic substrates, is at an early stage of development, and thus a comprehensive experimental and theoretical modeling study is needed to understand the fabrication and reliability of embedded passives before they can be widely used. This thesis aims to fabricate embedded passives in a multilayered organic substrate, perform extensive electrical and mechanical reliability tests, and develop physics-based models to predict the thermo-mechanical reliability of embedded capacitors. Embedded capacitors and resistors with different geometric shapes, planar dimensions, and thus different electrical characteristics have been fabricated on two different test vehicles. Capacitors are made with polymer/ceramic nanocomposite materials and have a capacitance in the range of 50 pF to 1.5 nF. Resistors are carbon ink based Polymer Thick Film (PTF) and NiCrAlSi and have a resistance in the range of 25 to 400 k. High frequency measurements have been done using Vector Network Analyzer (VNA) with 2 port signal-ground (S-G) probes. Accelerated thermal cycling (-55 to 125oC) and constant temperature and humidity tests (85oC/85RH) based on JEDEC and MIL standards have been performed. Furthermore, physics-based numerical models have been developed and validated using the experimental data. By focusing on the design and fabrication as well as the experimental and theoretical reliability assessments, this thesis aims to contribute to the overall development of embedded passive technology for Digital and Radio Frequency (RF) applications.

This dissertation aims at identifying and analysing different passive constructions in Catalan and providing a unified proposal to analyse passives cross-linguistically. In this respect, following Embick (2004), we identify three different passive constructions in Catalan: eventive, resultative and stative. However, we modify the definition of the so-called stative passive: it is the passive structure created from stative verbs. Specifically, we consider verbs that express Kimian states (Maienborn 2005) to be stative. We conduct our research from the neoconstructionist view that the internal syntax of the VP determines its formal event structure and the thematic interpretation of its arguments, conceived as entailments from event structure. Consequently, we assume that lexical aspect is configurationally derived from event structure. The key contribution of this dissertation is a new outlook on the formation of passive structures as lexicalisation patterns of event structure in a nanosyntactic model such as the one presented in Ramchand (2008, 2018).

Abstract:
Dans cette thèse, nous nous interrogeons sur les principales réformes entreprises au cours des années quatre-vingt-dix dans le but d'améliorer l'efficacité économique des systèmes d'indemnisation du chômage. Ainsi, dans un premier temps, les effets d'une réduction du niveau général de l'indemnisation du chômage sont analysés en prenant en compte les comportements d'épargne des travailleurs. Une analyse des conséquences en termes d'ajustement dynamique a alors permis de rejeter les résultats de la littérature, selon lesquels il serait souhaitable, pour améliorer le bien-être social, de réduire le niveau de l'indemnisation du chômage. Un instrument largement utilisé dans l'ensemble des pays de l'OCDE, les conditions d'éligibilité, a aussi fait l'objet d'une analyse minutieuse. Il s'agissait de clarifier l'impact que peut avoir une modification de la durée de l'indemnisation du chômage, ainsi que de la période de qualification ouvrant droits aux prestations. Ces conditions d'éligibilité introduisent, en effet, une certaine hétérogénéité chez les chômeurs dont les comportements dépendront de leur statut au regard du régime d'indemnisation. Les effets d'une modification des critères d'éligibilité sur le chômage apparaissent alors indéterminés et faibles. Toutefois, en termes de bien-être, le décideur public peut être amené à opérer des choix en fonction de ses objectifs sociaux: favoriser le bien-être social agrégé ou favoriser le sort des individus les plus désavantagés sur le marché du travail. Enfin, le troisième thème abordé dans la thèse est celui de la conversion des allocations chômage en subventions pour les entreprises. Cette mesure qui semble favorable à l'embauche des chômeurs les plus handicapés sur le marché du travail, comme les chômeurs de longue durée, peut voir son efficacité réduite si les salaires augmentent avec la subvention accordée aux employeurs.

Il y est montre que l'ordre de base de cette langue est l'ordre sujet-verbe-objet. Le chapitre 1 (45p. ) a pour objet d'exposer les constructions passives discutees par les grammairiens arabes et d'esquisser et de commenter les traitements qu'ils ont proposes pour ces constructions. Le chapitre 2 (43p. ) presente les constructions passives, dites avec complement d'agent, qui n'existe pas en arabe classique mais utilisees en arabe standard moderne. Le chapitre 3 (39p. ) discute de la definition de la notion de "passif" et argumente en faveur de l'emploi de cette notion a propos des structures syntaxiques arabes presentees aux chapitres 1 et 2.

This thesis deals with the passives constructions of the arabic language which includes both classical arabic and modern standard arabic. It describes these constructions and parses them using the modern techniques of transformational generative grammar. This study consists of eight chapters and one annexe which presents the passive and active verbal morphology in arabic. Preliminary chapter (68p. ) deals with two crucial topics for the analysis of the passives constructions: the first is the verb-subject agreement in arabic and the second is the determining of the rewriting base rule of the arabic sentence. It shows that the base word order in arabic is subject-verb-object. Chapter 1 (45p. ) exibits the passives constructions discussed by the arab grammarians and gives a detailed exposition of the analysis which they proposed for these constructions. Chapter 2 (43p. ) exhibits the passives constructions (with agent complement) used in modern standard arabic only. Chapter 3 (39p. ) deals of the definition of the notion "passive" and argues for using this term for the arabic constructions described in chapters 1 and 2. Chapter 4 (69p. ) treats of the passives constructions which have the order subject-verb-(objet) at surface structure. It argues that these constructions are derived by a transformational rule. Chapter 5 (65p. ) treats of the passives constructions which have the order verb-subject-(object) and argues that they are base generated structures. Chapters 6 (25p. ) and 7 (29p. ) discuss the analysis of the passives constructions lacking a lexical subject and the archaic constructions used in classical arabic respectively

Ce travail de thèse est sur la réalisation et la caractérisation de guides d’ondes planaires à base des verres chalcogénures pour des applications passives et actives. Les applications passives sont étudiées avec les verres à base énergie de phone pour le projet spatial européen DARWIN visant à trouver des exo plane��te pouvant abriter la vie. Le verre TGG (Te₇₅Ge₁₅Ga₁₀) a été sélectionné pour sa grande fenêtre de transparence de 2 à 20 µm. Une procédure de purification et de synthèse a été mise au point pour obtenir des verres ayant une atténuation moyenne de l’ordre de 0,5 dB/cm. Des couches antireflets ont été déposées sur ce verre, réduisant considérablement les pertes optiques par réflexion en passant d’environ 45% à moins de 5% dans une large bande spectrale de 10-20 µm. Il a été démontré que ce verre est stable dans le temps et sous irradiation et il satisfait aux spécifications d’utilisation dans l’espace. Les propriétés actives de verres de chalcogénures ont été étudiées avec des couches minces et guides d’onde planaires, fabriqués en utilisant la pulvérisation cathodique ou le PLD (Pulsed Laser Deposition) avec un verre de base ayant la composition Ga₅Ge₂₀Sb₁₀S(Se)₆₅. Le guidage de lumière a été démontré avec une perte mesurée d’environ 1 dB/cm à 1. 55 µm. La fluorescence a été observée dans ces guides d’onde planaires dopés aux ions Er³⁺ et un gain on/off de 4,4dB (3,4 dB/cm) a été obtenu à 1,54 µm. Deux compositions, Ge₁₅Sb₂₀S₆₅ et Ge₂₅Sb₁₀S₆₅ dans le même système vitreux ont été étudiées pour sélectionner un verre ayant un meilleur compromis entre le l’indice non linéaire et le coefficient d’absorption non linéaire. L’étude focalisée sur la deuxième composition a permis de démontrer l’effet Kerr dans ce matériau. Et pour la 1ère fois, la propagation d’un soliton spatial a été observée dans un guide d’onde en verre de chalcogénure
This work is on the fabrication and characterisation of planar waveguide based on chalcogenide glasses for passive and active applications. The passive applications have been studied in the framework of the European spatial program DARWIN aiming at the discovery of earth like planets. The tellurium based TGG glass with the composition of Te₇₅Ge₁₅Ga₁₀ has been selected for its wide transmission window from 2 to 20 µm. A purification and fabrication process has been established in order to obtain glasses with an attenuation of about 0. 5 dB/cm. Antireflection coatings have been developed and optical losses due to reflection have been reduced from 45% to about 5% over a large spectral region of 10-20 µm. It has been demonstrated that this glass is stable as function of time and under irradiation, and it meets the specifications for uses in space. The active properties of chalcogenide glasses have been studied with thin films and planar waveguides, fabricated with sputtering or pulsed laser deposition, by using Ga₅Ge₂₀Sb₁₀S(Se)₆₅ as base glass composition. Light guiding has been obtained with losses of 1 dB/cm at 1. 55 µm. Fluorescence has been measured in the Er³⁺ doped planar waveguides and an on/off gain of 4. 4dB (3. 4 dB/cm) has been obtained at 1. 54 µm. Two glass compositions, Ge₁₅Sb₂₀S₆₅ et Ge₂₅Sb₁₀S₆₅ and Ge25Sb10S65, in the same glass forming system have been studied in order to select the one having the best compromise of non linear refractive index and non linear absorption. Studies on the second glass composition have led to the demonstration of Kerr effect in this glass and spatial soliton propagation has been achieved for the first time in chalcogenide glasses

Abstract:
This study investigates passive and impersonal constructions in three Romance dialects of Italy: Sicilian, Abruzzese and Tuscan. The aim of this investigation is twofold: one the one hand I aim to contribute to the documentation of the dialects of Italy, and on the other, I aim to build on existing theories on passive and impersonal constructions. Whilst there is to date no detailed discussion of passive structures in Italo- Romance dialects, works such as Cennamo (1997), Ledgeway (2009) and Rohlfs (1969) suggest that passive structures are unpopular in the dialects of Italy. I explore the extent to which the passive is rejected in each dialect, and, where it is not used, which constructions are used in its place. From the data I have collected on passive constructions in these three dialects, a pattern emerges: the acceptability of the passive directly relates to the transitivity of the verb. Whilst the tolerance of the passive varies from dialect to dialect, one consistent result is that passives are affected by the ranking of the verb on the Transitivity Hierarchy (Hopper and Thompson 1980) and its entailments. This thesis presents interesting findings on si impersonals, uno, third person plural impersonals and the Abruzzese nome, which of particular interest, and which I claim is an impersonal clitic, that holds a plural feature. Throughout my discussion of impersonals, I develop a hierarchy of impersonals, which is based on the semantic features (+/- referential, +/- definite, +/- irrealis) of each impersonal type. This hierarchy captures all of the impersonal types found in the three dialects, and allows for cross-dialectal analysis. I present novel findings relating to the Tuscan first person plural impersonal si and the split in its usage, which, to my knowledge has not yet been discussed in the relevant literature. The data show that Tuscan first person plural impersonal si can be used with transitive and unergative verbs but not with unaccusatives. I propose a reason for this split, which is based on what I term agreement features (person, number, gender). As well as providing a detailed analysis of each impersonal type, I attempt to refine existing definitions of impersonals and propose that all types of impersonal constructions can be defined by their deficiency in one of the three agreement features, in other words, they are ‘feature deficient constructions'.

Ainsi, les températures apparentes mesurées par un satellite comme SMOS par exemple atteignent souvent des valeurs qui conduisent à des échecs d’inversion de l’humidité du sol. L’objectif de notre projet est d’étudier le phénomène des RFI à petite échelle, son impact sur les micro-ondes passives en bande L à partir des mesures au sol réalisées à l’aide de radiomètres. Une fois l’impact caractérisé de manière rigoureuse, une méthode de filtrage adaptatif a été développée pour corriger les effets. Le projet est composé de trois parties principales. La mise en place d’une expérimentation est réalisée afin de faire des mesures au sol à l’aide de deux radiomètres en bande L. Les mesures sont faites dans des conditions variables et plusieurs scénarios ont été considérés. Ensuite, les données sont collectées et analysées. Cette phase a abouti au développement d’un filtre qui permet d’atténuer l’effet des RFI sur les températures de brillance bruitées. Enfin, le filtre proposé dans le projet a été appliqué sur des données aéroportées en bande L prises sur le site Boreal Ecosystem Research and Monitoring Sites (BERMS) en Saskatchewan. L’expérimentation s’est déroulée à la station SIRENE de l’Université de Sherbrooke. Les instruments ont été mis en place et les radiomètres ont été calibrés en premier lieu pour s’assurer de la fiabilité des mesures. L’émetteur a servi comme une source d’interférence pour les radiomètres. Il était placé à des positions différentes vis-à-vis de ces derniers, et émettait à des puissances variables. Les différents scénarios considérés étaient utiles pour étudier l’effet de la position de la source RFI, ainsi que l’effet de la puissance émise par celle-là sur les températures mesurées par les radiomètres. Pour les mesures, nous avons utilisé un radiomètre multi-bandes qui nous a permis d’étudier l’impact de la bande passante sur les RFI. L’analyse et le traitement des données prises ont conduit au développement d’un filtre coupe-bande permettant de corriger les températures bruitées lorsque les caractéristiques du bruit sont connues. Ce filtre a été appliqué sur des données aéroportées bruitées. Le bruit a pu être atténué pour les températures en polarisation V. Les résultats de l’application du filtre sont satisfaisants dans l’ensemble malgré le volume important de données bruitées sur la zone d’étude. En ce qui concerne les données de la polarisation H, elles n’ont pu être corrigées, car elles étaient presque entièrement bruitées. Le mémoire porte sur une expérimentation originale, car les expériences du genre sont très rares dans la littérature. L’étude s’appuie sur deux radiomètres en bande L, ce qui est très particulier, compte tenu de la rareté de ces instruments.

Abstract:
Cette thèse est consacrée à l'étude des images polarimétriques multispectrales actives et hyperspectrales passives. Notre objectif est d'évaluer l'apport des mesures polarimétriques et / ou multispectrales pour améliorer l'estimation de paramètres et la détection en imagerie optronique. Tout d'abord, nous caractérisons la précision de l'estimation du degré de polarisation en imagerie polarimétrique active. Nous proposons deux modalités d'imagerie pour estimer le degré de polarisation, selon que le faisceau illuminant la scène est spatialement uniforme ou non. Dans chacun de ces cas nous évaluons la BCR (Borne de Cramer-Rao) et les performances d'estimateurs (biais et variance) reposant sur la moyenne empirique. Nous proposons ensuite une procédure d'estimation du degré de polarisation efficace et robuste aux variations spatiales lentes d'illumination. Dans une seconde partie, nous concevons et caractérisons des méthodes de détection de cibles sur les images hyperspectrales passives. L'enjeux consiste à extraire l'information pertinente de la masse de données contenue dans les images pour une tâche de détection d'anomalies. Nous proposons deux procédés : la sélection de bandes spectrales et la réduction de résolution spectrale. De cette façon, nous montrons qu'il peut exister un compromis entre le nombre de paramètres à estimer et l'efficacité de détection. Nous concluons cette partie en proposant une méthode d'amélioration du contraste dans une région d'intérêt sélectionnée. Enfin, dans une dernière partie, nous évaluons l'amélioration des performances de détection qu'il est possible d'atteindre avec des systèmes d'imagerie actifs qui combinent des mesures polarimétriques et multispectrales
This thesis is dedicated to the study of polarimetric multispectral active images and hyperspectral passive images. Our goal is to evaluate the added value of using polarimetric and / or multispectral measurements to improve the estimation of parameters and the detection capabilities of optronics systems. We first characterize the precision of the estimation of the degree of polarization in active polarimetric images. We propose two imaging modalities to estimate the degree of polarization depending on whether the laser beam illuminating the scene is uniform or not. In both cases, we compute the CRLB (Cramer-Rao Lower Bound) and the performances of estimators (bias and variance) based on the empirical mean. We then propose an estimation method that is efficient and robust to slow spatial variations of the illumination. Secondly, we design and characterize target detection methods for hyperspectral images. The problem here consists of extracting the relevant information from the amount of data contained in an image for an anomaly detection task. We propose two approaches : the selection of spectral bands and the reduction of the spectral resolution. In this way, we show that it can exist a trade-off between the number of parameters to estimate and the detection efficiency. We then propose a method to improve contrast in a selected region of interest. In the last part of this manuscript, we evaluate the detection performance improvements provided by active imaging devices that combine polarimetric and multispectral measurements

Abstract:
Dans le but d'améliorer la connaissance du régime thermique des marges continentales divergentes, nous avons développé un travail qui s'est successivement articulé autour d'un volet méthodologique, de nouvelles estimations du flux de chaleur et de modélisations numériques. Afin d'exploiter au mieux les données issues de l'exploration pétrolière, active sur un certain nombre de marges continentales, nous avons développé une méthode basée sur les réseaux de neurones pour estimer la conductivité thermique à partir d'un jeu de diagraphies géophysiques. Ensuite, nous avons réalisé un travail d'inter-comparaison des méthodes pour corriger les températures pétrolières de fond de trou, en nous appuyant sur un large ensemble de données provenant de forages en Australie. La méthodologie ainsi développée a été appliquée sur plusieurs marges anciennes, à l'est du Canada, en Afrique du Sud et en Australie. Les résultats obtenus suggèrent que le flux de chaleur mantellique est plus élevé sur les marges que sur le continent -- et possiblement l'océan -- adjacents, contredisant ainsi les modèles classiques d'évolution thermique des marges. Les mesures issues d'une campagne océanographique de flux de chaleur sur une marge jeune, dans le Golfe d'Aden, sont elles aussi significativement plus élevées que les prédictions des modèles classiques. Ces résultats sont compatibles avec des modélisations numériques qui placent les marges continentales à l'échelle de la convection du manteau, et montrent systématiquement une augmentation du flux de chaleur vers la bordure du continent sur une distance d'au moins 200 km, qui perdure indéfiniment. Les conclusions de ce travail de thèse pourraient apporter un nouvel éclairage sur les modes de déformation des marges continentales et l'évolution des systèmes pétroliers
In order to gain insights into the thermal regime of divergent continental margins, we successively developed a methodological part, estimated new heat flow values and performed numerical modelings. So as to use efficiently data from oil exploration, which is active on a number of continental margins, we set up a new method based on the neural network technique, relating a set of geophysical well logs to the thermal conductivity. We then performed an inter-comparison of several methods to correct bottom-hole temperatures from oil exploration, using a comprehensive data set from boreholes in Australia. We applied this methodology on several old margins, in eastern Canada, South Africa and Australia. The results we obtained suggest that mantle heat flow is higher on the margins than on the adjacent continent -- and possibly that on the adjacent ocean -- thereby contradicting the classical model of thermal evolution of continental margins. Heat flow measurements performed during a scientific cruise on a young margin, in the Gulf of Aden, are also significantly more elevated than the predictions of the classical models. These results are in agreement with numerical modelings that set the continental margins at the scale of the mantle convection, and show systematically an increase of heat flow towards the border of the continent on a minimum distance of 200 km, which remains permanently. The findings of this PhD work could bring new perspectives on the mechanisms of deformation of continental margins and the evolution of petroleum systems

Abstract:
Les modeles de formation et d'evolution des marges continentales passives n'ont pu etre elabores, modifies et testes que parce que de nombreux leves geologiques et geophysiques de detail ont ete acquis. D'ou : au cours de l'episode de rifting, les directions des mouvements des plaques amerique du nord, europe et iberie sont identiques aux directions d'ouverture du domaine oceanique adjacent. Il faut quantifier l'extension totale resultant du rifting ce qui necessite de mieux apprehender les processus de formation des marges. Les donnees de la marge ouest-iberique sont cependant compatibles avec le modele d'etirement uniforme. Ce type de marge pourrait etre considere comme l'evolution finale d'un bassin intra-continental symetrique cree par etirement uniforme. En ce qui concerne la marge nord-gascogne, on suppose qu'une surface de decollement, traversant toute la croute superieure jusqu'a l'interface fragile-ductile, a fonctionne des le debut de la phase de rifting. Les failles limitant les blocs bascules sont alors des failles antithetiques. Ce type de marge pourrait etre considere comme l'evolution finale d'un bassin intra-continental asymetrique. A titre d'hypothese, on propose un modele de formation de marge continentale par etirement uniforme.
