Abstract:
Objectifs : L’étude a été conduite pour évaluer la ressemblance agromorphologique des descendances hybrides F1 NJM x GVT à celles de leurs géniteurs en Côte d’Ivoire en vue de prédire les caractéristiques des descendants et adopter des techniques culturales et utilisations appropriées. Méthodologie et résultats : Trente variables ont été mesurées sur 18 descendances et leurs géniteurs mâles GVT et femelle NJM. Il ressort que les caractéristiques végétatives des descendances NJM x GVT sont relativement proches de leurs géniteurs mâles GVT. Les héritabilités varient de 10 % à 40 % pour l’ensemble des descripteurs. Elle est plus élevée pour C20, LGF, ILE, ILPRF et Déq avec une valeur de 40 % qui ont plus contribué au rapprochement des descendances de leur géniteur mâle. Des gains agromorphologiques par rapport aux deux géniteurs sont observés pour la plupart des caractères. Les taux varient en moyenne de 0,73 % à 84,26 % selon le caractère et le géniteur. Conclusion et applications des résultats : Ces résultats serviront de guide aux sélectionneurs quant aux résultats attendus d’une descendance F1 de cocotier Grand croisé par cocotier Nain. Ces hybrides peuvent être cultivés et utilisés de la même manière que leur géniteur mâle. Mots clés : Cocotier, caractéristique agromorphologique, hybride NJM x GVT, héritabilité, gain. Assessment of agromorphological similarities between parents and F1 progenies in the crossing of Dwarf Malayan x Vanuatu Tall coconuts in Côte d’Ivoire ABSTRACT Objectives: The study was conducted to assess the agromorphological resemblance of the F1 NJM x GVT hybrid progenies to those of their parents in Côte d'Ivoire in order to predict the characteristics of the descendants and adopt appropriate cultivation techniques and uses. Methodology and results: Thirty variables were measured on 18 descendants and their male parents GVT and female NJM. It appears that the vegetative characteristics of the NJM x GVT descendants are relatively close to their male GVT sires. Heritability ranges from 10% to 40% for all descriptors. It is higher for C20, LGF, ILE, ILPRF and Déq with a value of 40% that contributed more to the approximation of the descendants of their male parent. Agromorphological gains compared to the two spawners are observed for most characters. The rates vary on average from 0.73% to 84.26% depending on the trait and the sire. Conclusion and application of the results: These results will serve as a guide for breeders as to the expected results of an F1 offspring of large coconut palm crossed by Dwarf coconut tree. These hybrids can be grown and used in the same way as their male parent. Key words: Coconut palm, agromorphological characteristic, NJM x GVT hybrid, heritability, gain.

Abstract:
Many authors, both in Hungary and abroad, have reported on experiments carried out to determine the role of sowing time in maize, but the results are often contradictory. This is hardly surprising, since the maize plant exhibits enormous genetic variability and the hybrids created through selection and inbreeding may have very specific requirements as to sowing date. The year effect, too, often complicates the efforts of scientists to provide clear guidance to farmers on the optimal sowing date for each hybrid.

Abstract:
Hybrid male sterility (HMS) contributes to speciation by restricting gene flow between related taxa. Detailed cytological characterization of reproductive organs in hybrid males is important for identifying phenotypes that can help guide searches of speciation genes. To investigate possible cellular causes of HMS, we performed crosses between closely related species of the Anopheles gambiae complex: An. merus with An. gambiae or An. coluzzii . We demonstrate that HMS in African malaria mosquitoes involves two defects in the reciprocal crosses: a premeiotic arrest of germline stem cells in degenerate testes and a failure of the reductional meiotic division of primary spermatocytes in normal-like testes. The premeiotic arrest in degenerate testes of hybrids is accompanied by a strong suppression of meiotic and postmeiotic genes. Unlike pure species, sex chromosomes in normal-like testes of F1 hybrids are largely unpaired during meiotic prophase I and all chromosomes show various degrees of insufficient condensation. Instead of entering reductional division in meiosis I, primary spermatocytes prematurely undergo an equational mitotic division producing non-motile diploid sperm. Thus, our study identified cytogenetic errors in interspecies hybrids that arise during the early stages of postzygotic isolation.

Abstract:
This study investigated pilots' taxi performance, situation awareness and workload while taxiing with three different head-up display (HUD) symbology formats: Command-guidance, Situation-guidance and Hybrid. Command-guidance symbology provided the pilot with required control inputs to maintain centerline position; Situation-guidance symbology provided conformal, scene-linked navigation information; while the Hybrid symbology combined elements of both symbologies. Taxi performance was assessed with average taxi speed and root mean square error (RMSE) from the centerline. Situation awareness and workload were assessed using a 3- Dimension SART and a 7-point scale, respectively. Taxi speeds were highest and RMSE from centerline lowest with Situation-guidance and Hybrid symbologies. Situation awareness was highest and workload lowest with Situation-guidance and Hybrid symbologies. These results are thought to be due to cognitive tunneling induced by the Command-guidance symbology. Situation-guidance (and Hybrid) HUD symbologies provided a common reference with the environment, which may have supported better distribution of attention.

Abstract:
A challenging rescue task for the underground disaster is to guide survivors in getting away from the dangerous area quickly. To address the issue, an escape guidance path developing method is proposed based on anisotropic underground wireless sensor networks under the condition of sparse anchor nodes. Firstly, a hybrid channel model was constructed to reflect the relationship between distance and receiving signal strength, which incorporates the underground complex communication characteristics, including the analytical ray wave guide model, the Shadowing effect, the tunnel size, and the penetration effect of obstacles. Secondly, a trustable anchor node selection algorithm with node movement detection is proposed, which solves the problem of high-precision node location in anisotropic networks with sparse anchor nodes after the disaster. Consequently, according to the node location and the obstacles, the optimal guidance path is developed by using the modified minimum spanning tree algorithm. Finally, the simulations in the 3D scene are conducted to verify the performance of the proposed method on the localization accuracy, guidance path effectiveness, and scalability.

Abstract:
Field trials were conducted in 2008, 2009 and 2011 to assess fumonisin contamination in transgenic (Bt) and non- Bt maize hybrids infested with European corn borer, corn earworm, and Western bean cutworm. Comparisons were made among maize hybrids expressing two transgenic insect resistance proteins (Cry1Ab × Vip3Aa), a single resistance protein (Cry1Ab), or no insect resistance. The field design was a randomised complete block design with four replicates of each hybrid × insect combination. Kernel injury, Fusarium ear rot, and fumonisins (FB1+FB2+FB3) in maize grain were measured. These measurements differed significantly among years of the study. In all years, significant positive correlations were present between insect injury and Fusarium ear rot, insect injury and grain fumonisin levels, and Fusarium ear rot and grain fumonisin levels. Under all insect infestation treatments, Cry1Ab × Vip3Aa hybrids were the most resistant of the hybrids with regard to any of the grain quality measurements. Averaged over all insect infestations and years, insect injury, Fusarium ear rot, and grain fumonisin levels were all low in Cry1Ab × Vip3Aa (0.1% and 2.2% of total kernels, and 0.56 mg/kg, respectively). The highest average levels of insect injury, Fusarium ear rot, and grain fumonisin contamination (3.3% and 7.2% of total kernels, and 5.47 mg/kg, respectively) were found in the non-Bt hybrids. The presence of transgenic insect protection (Cry1Ab × Vip3Aa or Cry1Ab) resulted in significant reductions in all grain quality measurements as compared with the non- Bt hybrids. Only grain obtained from Cry1Ab × Vip3Aa hybrids consistently had acceptable fumonisin content according to both US guidance levels and EU regulatory limits. These results indicate that Cry1Ab × Vip3Aa maize hybrids are more likely to yield high quality, low-fumonisin grain compared to hybrids expressing only Cry1Ab or lacking insect resistance.

Abstract:
The efficiency of cacao breeding program can be increased by choosing superior crosses to be made between divergent clones. We assessed the genetic distance among five clones with RAPD data (genetic distance - GD) and with yield component data (Mahalanobis distance - MD). The clones were evaluated in a diallel, during five years, for five yield components. A total of 130 RAPD bands were scored. GD and MD were used to determine the correlation between genetic distances among clones and the performance of their hybrids. The correlation between GD and MD was 0.67 (P=0.03). Both distances were related to heterotic performance of hybrids for wet seed weight/plant and wet seed weight/fruit. The average hybrid performance for the same two yield components was correlated with only MD. Hence, genetic distances measured by RAPD and yield components can be used as a guide to the choice of the superior crosses.

Abstract:
La connaissance de l’attitude, de l’altitude, de la segmentation du sol et du mouvement est essentielle pour la navigation d’un drone, en particulier durant les phases critiques de décollage et d’atterrissage. Dans ce travail de thèse, nous présentons un système stéréoscopique hybride composé d’une caméra fisheye et d’une caméra perspective pour estimer les paramètres de navigation d’un drone. À partir de ce capteur, une approche systémique est proposée. Contrairement aux méthodes classiques de stéréovision basées sur l’appariement de primitives, nous proposons des méthodes qui évitent toute mise en correspondance entre les vues hybrides. Une technique de plane-sweeping est suggérée pour déterminer l’altitude et détecter le plan du sol. La rotation et la translation du mouvement sont ensuite découplés : la vue fisheye contribue à évaluer l’attitude et l’orientation tandis que la vue perspective contribue à apporter l’échelle métrique de la translation. Le mouvement peut ainsi être estimé de façon robuste et à l’échelle métrique grâce à la connaissance de l’altitude. Cette méthode repose sur l’algorithme des 2-points complété par un filtre de Kalman. Nous proposons des approches robustes, temps réel et précises, exclusivement basées sur la vision avec une implémentation C++. Bien que cette approche évite l’utilisation de capteurs autres que les caméras, ce système peut également être appuyé par une centrale inertielle
Knowledge of attitude, altitude, ground plane segmentation and motion is essential for an Unmanned Aerial Vehicle during critical maneuvers such as landing and take-off. In this thesis we present a hybrid stereoscopic rig composed of a fisheye and a perspective camera for visionbased navigation. This sensor is then exploited by systemic methods. In contrast to classical stereoscopic systems based on feature matching, we propose methods which avoid matching between hybrid views. A planesweeping approach is proposed for estimating altitude and detecting the ground plane. Rotation and translation are then estimated by decoupling : the fisheye camera contributes to evaluating attitude, while the perspective camera contributes to estimating the scale of the translation. The motion can be estimated robustly at the meter scale, thanks to the knowledge of the altitude. Our method uses a 2-point algorithm complemented by a Kalman filter. We propose a robust, real-time, accurate, exclusively vision-based approach with a C++ implementation. Although this approach removes the need for any non-visual sensors, it can also be coupled with an Inertial Measurement Unit

Abstract:
Les fibres à cristaux photoniques sont constituées d’un réseau périodique transverse de diélectriques. En introduisant un défaut dans ce réseau, il est possible de guider la lumière par un effet de bandes interdites photoniques, dont les propriétés diffèrent fondamentalement du guidage par réflexion totale interne qui a lieu dans les fibres conventionnelles. Nous étudions en particulier les fibres à bandes interdites photoniques solides, comportant des inclusions dont l’indice de réfraction est supérieur à celui de la matrice. En insérant des trous d’air dans cette structure solide, on observe une forte diminution des pertes par confinement et par courbure. De plus, la présence de trous d’air entre les inclusions de haut indice rend possible l’accord de phase entre deux modes fondamentaux, pour la génération du 2nd ou 3ème harmonique. Il est également possible dans ces fibres de générer efficacement un supercontinuum et d’en contrôler l’étendue spectrale grâce aux propriétés de dispersion particulières
This thesis focuses both on theoretical and experimental studies of a recent class of Photonic Crystal Fibers (PCF): the solid-core PCF which guide light thanks to a Photonic BandGap (PBG) effect. The main goal of this work is then to better understand their propagation mechanisms (in order to improve their transmission properties) as well as to explore their potentials for non linear purposes. The study of these fibers (dispersion diagrams interpretation, emphasis of a scaling law and also of a light level of bend losses restrictive for their practical uses) leads us to develop a new kind of PCF for which wave guidance is a combination of PBG effect and more common Total Internal Reflexion (TIR). These fibers, called hybrid PCF, are made here by adding air holes in the all-solid structures previously studied. Particularly, two hybrid structures are proposed and fabricated, exhibiting a huge reduction of confinement and bend losses. Finally, we show that their unique disoersive properties enable to obtain a phase index matching between two fundamental modes (one is guided by PBG and the other by TIR) for second or third harmonic generation, and to effectively generate a supercontinuum for which the spectral broadening can be controlled by the opto-geometrical properties of the structure

Abstract:
Le travail présenté dans ce mémoire de thèse concerne l'étude et la mise en oeuvre de méthodes de fusion d'informations pour la localisation 3D d'un véhicule terrestre en environnement urbain dense. L'approche étudiée est la fusion des mesures fournies par le système de navigation absolue GPS multi-porteuses et les capteurs de navigation estimes odomètre et gyromètre. Ces mesures sont hybridées à l'aide de filtres récursifs pour l'estimation de la position. On réalise l'étude de l'estimateur de position en deux étapes. La première étape concerne l'étude et la mise en oeuvre d'un estimateur pour la fusion des observables de code et de phase du GPS multi-porteuses. L'expérimentation sur données synthétiques et réelles montre que le système proposé permet d'augmenter la précision des mesures lorsque la puissance du bruit sur chaque porteuse est du même ordre de grandeur. La deuxième étape concerne le système d'hybridation serrée qui fournit une estimation de la direction du véhicule et des pseudo-distances satellite-récepteur, même en absence de mesures GPS. Dans ce cadre, nous proposons un filtre circulaire récursif qui permet d'estimer la direction du véhicule. Le filtre d'hybridation réalise la fusion centralisée des mesures de pseudo-distances corrigées et la fusion distribuée des observables de phase avec les mesures gyrométriques et odométriques. L'expérimentation réalisée dans un contexte synthétique et réel montre que le système proposé est au moins aussi précis que le système d'hybridation lâche habituellement utilisé en pratique.

Abstract:
La thèse propose un concept de microbancs optiques reconfigurables (MOEMS 3D hybrides) à base d'éléments microfabriqués et assemblés à l'aide d'une station robotique : ces nouveaux bancs optiques combinent les avantages du micro-assemblage robotique et des techniques de microfabrication sur silicium. Le positionnement fin des supports optiques sur un substrat s'effectue par une tâche de guidage. La réalisation d'une telle tâche à l'échelle micrométrique est une contribution majeure de la thèse. Elle a nécessité plusieurs avancées. L'absence de modèles fiables et de mesures disponibles pour des contacts plan/plan, un type de contact très fréquent en micro-assemblage, nous a conduit au développement d'un banc de mesure robotisé pour évaluer la force de pull-off. Ensuite, un système robotique équipé de préhenseur à deux doigts de serrage instrumentés a été mis en oeuvre pour mesurer simultanément la force de serrage et la force de contact latéral qui agit sur le micro-objet manipulé durant le guidage. Un modèle de l'évolution de la force de serrage lors de l'apparition de la force de contact latéral est présenté et confronté à une modélisation par éléments finis ainsi qu'à des résultats expérimentaux. Enfin, une stratégie de guidage est établie en prenant en compte la stabilité de la saisie et les spécificités du micromonde. Une commande hybride force/position est choisie pour automatiser le guidage par deux doigts instrumentés (GDDI). Elle a été mise en oeuvre avec succès sur un système robotique.

Abstract:
Les techniques liées au vol en formation et aux opérations de proximité de satellites autonomes font partie des technologies opérationnelles spatiales les plus marquantes et les plus ambitieuses de ces dernières années. En particulier, cela nécessite la complète maitrise des phases de rendez-vous proche et de survol par un satellite actif avec un satellite, une station ou un débris passif. Le développement de systèmes GNC (Guidage Navigation Contrôle) associés performants et sûrs repose sur la connaissance d'un modèle dynamique réalisant un bon compromis entre faible complexité et prise en compte suffisante des principales caractéristiques dynamiques et cinématiques de ce type de systèmes. La première partie de cette thèse est consacrée au développement d'une modélisation unifiée de la dynamique relative couplée entre un satellite coopératif chasseur et un satellite cible non coopérative. En effet, lorsque deux satellites sont proches l'un de l'autre, ils ne peuvent plus être traités comme des masses ponctuelles, car leur forme et leur taille affectent le mouvement relatif entre les points de masse décentralisés, conduisant à un couplage des mouvements de translation et de rotation. Ce développement est abordé de manière progressive: le mouvement de translation relatif non linéaire est décrit sous hypothèses képlériennes dans le repère orbital de la cible ainsi que le modèle linéarisé associé. Ensuite, le modèle non linéaire d'attitude relative est présenté au moyen des paramètres d'Euler-Rodrigues. Enfin, le formalisme des quaternions duaux est utilisé afin d'obtenir le modèle relatif couplé en translation et en attitude. La phase de modélisation du mouvement relatif linéaire de translation a ainsi permis de mettre en évidence certaines transformations de coordonnées conduisant à une caractérisation intéressante des trajectoires périodiques du chasseur et ainsi de proposer un premier type de loi de contrôle de guidage pour la phase d'approche et de survol. Dans l'ensemble de notre travail, nous considérons un chasseur équipé de propulseurs chimiques et l'hypothèse classique des poussées impulsionnelles. Ce type de systèmes dynamiques conciliant dynamique continue et contrôle impulsionnel se définit naturellement comme une classe particulière de systèmes dynamiques hybrides. Plusieurs lois de contrôle hybrides sont alors proposées afin de stabiliser le chasseur sur une trajectoire de référence périodique proche de la cible. Les propriétés de stabilité et de convergence de ces différentes lois sont analysées et de nombreuses simulations numériques montrent les forces et les faiblesses de chaque contrôleur en termes d'indices de performance comme le temps de convergence, la consommation ainsi que des contraintes de sécurité. Dans un second temps, des contraintes opérationnelles supplémentaires (contraintes de visibilité par exemple) sont prises en considération en imposant une direction d'approche rectiligne (glideslope) au chasseur. Cette trajectoire impose au satellite chasseur de suivre une droite dans n'importe quelle direction du repère local reliant l'emplacement courant du chasseur à sa destination finale. Sous l'hypothèse de propulsion impulsionnelle, les résultats existant dans la littérature pour ce type d'approche ont été généralisés aux orbites elliptiques en identifiant une nouvelle formulation du problème comprenant des degrés de liberté utiles qui permettent de minimiser la consommation de carburant tout en contrôlant l'excursion de la trajectoire libre en dehors de la droite de glideslope en la confinant dans un couloir d'approche défini par l'utilisateur. La synthèse des lois de guidage ainsi obtenues repose sur la résolution de problèmes d'optimisation SDP dans le cas général ou linéaire pour les cas plus simples d'approche standards du type V-bar ou R-bar
The techniques related to formation flying and proximity operations of autonomous satellites belong to the most significant and challenging operational space technologies of the last years. In particular, they require full mastery of the close-range rendezvous and observation phases by an active satellite with a passive satellite, station or debris. The development of efficient and safe associated GNC systems relies on the knowledge of a dynamic model that achieves a good trade-off between low complexity and sufficient inclusion of the main dynamic and kinematic characteristics of this type of systems.The first part of this thesis is devoted to the development of a unified modeling of the relative coupled dynamics between a cooperative chaser satellite and a non-cooperative target satellite. Indeed, when two satellites are close to each other, they can no longer be treated as point masses because their shape and size affect the relative motion between the decentralized points, leading to a translational-attitude motions coupling. This development is addressed in a progressive way: the relative nonlinear translational motion is described under Keplerian assumptions in the target's orbital reference frame, as well as the associated linearized model. Then, the nonlinear relative attitude model is presented by means of the Euler-Rodrigues parameters. Finally, the dual quaternion formalism is used to obtain the relative translational and attitude coupled model. The modeling phase concerning the linear relative translational motion has allowed us to highlight certain coordinates transformations leading to an interesting characterization of the chaser's periodic trajectories and thus, to propose a first type of control law for the close-phase rendezvous and observation phases.All along this work, we consider a chaser satellite equipped with chemical thrusters under the classical hypothesis of impulsive thrusts. This type of dynamic systems gathering continuous dynamics and impulsive control naturally belongs to a particular class of dynamical hybrid systems. Several hybrid control laws are then proposed in order to stabilize the chaser on a periodic reference trajectory close to the target. The stability and convergence properties of these different laws are analysed and several numerical simulations show the strengths and weaknesses of each controller in terms of performance indices such as convergence time, consumption and safety constraints. In a second step, additional operational constraints (line-of-sight constraints for example) are taken into account by imposing a rectilinear (glideslope) direction to the chaser. This trajectory requires the chaser satellite to follow a straight line in any direction of the local reference frame and connecting the current location of the chaser to its final destination. Under the impulsive propulsion assumptions, the results in the literature for this type of approach have been generalized to elliptic orbits by identifying a new formulation of the problem including useful degrees of freedom, which allow minimizing the fuel consumption while controlling the humps of the trajectory outside the glideslope line by enclosing it in a user-defined approach corridor. Guidance laws are therefore synthetized via the solution of an SDP optimisation problem in the general case and via a linear programming when considering standard cases like the V-bar or R-bar approaches

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2005.
Includes bibliographical references (p. 223-228).
This thesis proposes a hybrid route guidance system in which predictive guidance is generated in a centralized layer and revised in a reactive, decentralized layer that resides on-board the vehicle. This hybrid approach is intended to improve guidance quality by balancing the ability of the centralized layer to generate consistent guidance with the ability of the decentralized layer to respond rapidly to incidents. Centralized guidance is computed using a rolling-horizon Dynamic Traffic Assignment routine based on the Method of Successive Averages. This guidance is disseminated to equipped vehicles in the form of prescribed paths, which may be subsequently revised by an on-board decentralized layer. This decentralized layer revises only the local portion of the vehicle's path in order to limit the potential negative impact of its myopic reactive algorithm. The layer uses a simple splitting algorithm in order to heuristically balance demand on alternate paths. Both layers utilize data collected by guided vehicles. The centralized layer uses position data from guided vehicles. The decentralized layer uses local arc travel time data which is shared among guided vehicles.
(cont.) This approach follows the vision of a vehicle-centric route guidance system whose design is focused on the vehicle, rather than on stationary components. In order to test the performance of the proposed system, a small test network is simulated in a simple network simulator. The primary experimental questions are: whether the hybrid system provides higher quality route guidance than either a fully centralized or fully decentralized system; and how hybrid guidance quality is affected by various parameters of the system and the testing environment. Results of testing confirm that the hybrid system provides higher quality guidance than either centralized or decentralized systems in most scenarios; in no scenario is the hybrid system found to perform measurably worse than the centralized or decentralized system. The greatest benefits of the hybrid system are found to be in incident scenarios, supporting the hypothesis that the decentralized layer may aid incident response.

Chacun des doigts de la pince instrumentée est composé d’un actionneur piézo-électrique et d’un capteur de force piézorésistif intégré.

Une commande hybride force/position est utilisée pour automatiser le micro-assemblage. Dans cette commande, certains axes sont commandés en position et les autres sont commandés en force. Pour les axes commandés en force, une nouvelle commande fondée sur une commande en impédance avec suivi de référence est proposée selon un principe de commande non linéaire par mode glissant avec estimation des paramétres en lignes. En utilisant le schéma de commande hybride force/position proposé, une automatisation de toutes les tâches de micro-assemblage est réalisée avec succès, notamment sur un composant flexible à guider dans un rail
This work proposes the use of an active microgripper with sensorized end-effectors for the automationof the microassembly of 3D hybrid MOEMS. Each of the two fingers of the microgripper is composedof a piezoelectric actuator with an integrated piezoresistive force sensor. The integrated force sensorpresents innovative performances compared to the existing force sensors in literature. The forcesensors provide the ability to measure the gripping forces applied by the microgripper to grasp a microcomponentand estimated the contact forces between the microcomponent and the substrate ofmicroassembly. A dynamic nonlinear model of the microgripper is developed. A hybrid force/positioncontrol is used for the automation of the microassembly. In the hybrid force/position control formulation,some axes are controlled in position and others are controlled in force. For the force controlledaxes, a new nonlinear force control scheme based on force tracking sliding mode impedance controlis proposed with parameter estimation. Using the proposed hybrid force/position control scheme, fullautomation of the microassembly is performed, notably for the guiding of a flexible component in arail

Abstract:
L'accordabilite de la longueur d'onde du laser a fibre optique dopee erbium a l'aide d'un interferometre de type mach-zehnder integre sur un substrat de niobate de lithium (linbo 3) conjugue les talents respectifs de l'amplificateur a fibre dopee erbium et de l'optique integree sur linbo 3. Les forts gains atteints par la fibre dopee erbium ajoutes a un coefficient electro-optique du niobate de lithium des plus eleves demontrent une accordabilite spectrale continue de 24 nm de la longueur d'onde laser dans la troisieme fenetre des telecommunications optique pour des tensions variant entre 0 et 7 volts. Le laser est caracterise par un faible seuil d'oscillation de 5 mw de puissance pompe couplee a 980 nm et par un rendement de 4%. Les proprietes polarimetriques de la fibre laser associee a un ou deux polariseurs intracavites permettent, par une configuration laser et une birefringence adequates, d'accorder mecaniquement la longueur d'onde laser de la fibre dopee erbium sur une plage spectrale de 28 nm autour de 1550 nm par rotation de la lame quart d'onde d'un controleur de polarisation a fibre intracavite. Le laser est caracterise par un seuil d'oscillation de 4mw de puissance pompe couplee a 980 nm et un rendement de 20%. L'association des deux effets de filtrage, interferometrique accordable electro-optiquement a l'aide d'un interferometre de mach-zehnder fabrique par echange protonique et polarimetrique, demontre l'accordabilite electro-optique du laser a fibre dopee erbium dans une plage spectrale de 30 nm autour de 1550 nm pour des tensions variant entre 11 et +7 volts et pour deux positions differentes de la lame quart d'onde du controleur de polarisation a fibre. Le laser est caracterise par un seuil de 5 mw de puissance pompe couplee a 980 nm et un rendement de 5%.

Abstract:
Les matériaux photoluminescents ont un rôle important dans les applications liées à la photonique, l'optoélectronique ou l'éclairage. Leur combinaison avec des polymères conduit à des matériaux fonctionnels polyvalents faciles à mettre en forme. Dans ce contexte, des matériaux hybrides composés d'une matrice organique contenant des clusters métalliques octaédriques fortement luminescents ont été préparés. Ces luminophores présentent plusieurs avantages : une forte luminescence dans le rouge et le proche-IR, un rendement quantique élevé, un large décalage de Stokes et aucun effet de photoblanchiment ou de photoscintillement. Comme matrice hôte, le PMMA et le PDMS ont été utilisés en raison de leurs propriétés optiques, mécaniques et leur stabilité thermique. Cependant, une condition nécessaire pour réaliser les matériaux hybrides est d'introduire de manière homogène l'émetteur inorganique dans le polymère organique afin d'éviter les phénomènes de ségrégations. Pour cela, plusieurs approches d'intégration ont été développées. Les analyses spectroscopiques effectuées sur ces hybrides ont montré leur grand potentiel d’applications. Ceux-ci ont été utilisés pour concevoir un matériau imprimable à la lumière, sans encre et auto-effaçable, lorsque qu’il est combiné à un fluorophore organique ; ainsi que pour l’élaboration de guides d’ondes 1D et 2D. Les guides 1D peuvent être appliqués en photonique intégrée, tandis que les guides 2D combinés à des cristaux liquides conduisent à un nouveau matériau PDLC (Polymer Dispersed Liquid Crystal) applicable pour des concentrateurs solaires luminescents
Photoluminescent materials are playing a major role in applications related to photonics, optoelectronics or lighting. Combining them with polymers allows the design of easy-to-shape-functional materials with enhanced application versatility. Related to this, hybrid materials composed of an organic polymer matrix containing strongly luminescent octahedral metal clusters were prepared. Octahedral metal clusters have several advantages: a deep luminescence in the red and the near-IR region, a high quantum yield, a large Stokes shift and no photobleaching or photoblinking effects. As organic host matrices, PMMA and PDMS were used because of their optical and mechanical properties in addition to their thermal stability. However, a prerequisite for realizing hybrid materials is to homogeneously introduce the ceramic inorganic emitter in the organic polymer to avoid segregation-phase phenomena. For this purpose, several integration approaches were developed to prepare new hybrid materials. Meanwhile, spectroscopic analysis were performed on these hybrids demonstrating their huge potential. Actually, these hybrids were used to design a self-erasable inkless light-imprinting material when the hybrid is combined with an organic fluorophore, and 1D- and 2D-waveguides. The 1D-waveguides can be applied for integrated photonics while 2D-waveguides combined with liquid-crystals lead to a new luminescent PDLC (Polymer Dispersed Liquid Crystal) material for Luminescent Solar Concentrator technology

Abstract:
This paper describes some generic solid oxide and molten carbonate hybrid fuel cell gas turbine systems and dynamic modeling tools that are being developed to simulate the performance of these and other hybrid fuel cell systems. The generic hybrid systems are presented to introduce issues and technical development challenges that hybrid fuel cell gas turbine systems must address and to provide a platform for the development of the dynamic modeling tools. The present goals are to develop dynamic models for the basic components of solid oxide and molten carbonate fuel cell gas turbine hybrids, ensure their reliability, and obtain a basic understanding of their performance prior to integration into a complete hybrid system model. Preliminary results for molten carbonate and solid oxide fuel cell types are presented. These results provide understanding of some of the operational characteristics of fuel cells, and indicate the complexity of the dynamic response of fuel cell hybrid components. For the fuel cell models, generic planar designs are analyzed showing voltage and current behavior following step changes in load resistance and steady state performance curves. The results provide confidence in each of the model’s reliability, enabling them to be integrated for hybrid system simulation. Results from the integrated simulations will provide guidance on future hybrid technology development needs.

Abstract:
Standard buildings in steel and in reinforced concrete are constructed by two different industrial sectors with little interaction. Even steel-concrete composite buildings remain designed as steel structures, with a limited benefit of the presence of concrete slabs. For some years however, a more integrated design between both materials is used, merely in high rise and heavy loaded structures. This new trend is not supported by actual standards that give little guidance for the specific arrangements that come from this new practice. The RFCS SMARTCOCO research project is intended to fill these gaps in knowledge and provide design guidance for some composite elements covered neither by Eurocode 2 nor by Eurocode 4 : composite columns or walls reinforced by several fully encased steel sections, reinforced concrete columns reinforced by one steel section over the height of one storey and concrete flat slabs or beams connected to columns or walls by means of steel shear keys. Gaps in knowledge are mostly related to force transmission between concrete and embedded steel profiles. A generic design approach has been developed and then used to design test specimens. The results have been used to calibrate the design proposals. The output is a design guide which complements Eurocode 2 and 4.
