Abstract:
The Bi-directional Evolutionary Structural Optimisation (BESO) method had been used by many authors for the optimisation of structures. This work sets out to investigate the effect of key optimisation parameters utilized in the BESO method, the evolution rate and the filter radius, on the outcome of the optimisation. An understanding of the interaction of these factors in the optimisation process enables a more efficient way to produce optimised components that can fully capitalise on the capabilities of additive manufacturing.

Abstract: This research paper presents a comprehensive study on the topology optimization of a piston component manufactured through 3D printing technology. The study employs a combination of SolidWorks and ANSYS software to model and simulate the piston's structural behavior under different loading conditions. The optimized piston design is produced using PLA material through Ultimaker Cura software. The topology optimization process involves defining the design constraints and objectives, which are optimized to produce an optimal design with reduced weight while maintaining the required structural integrity. The paper investigates the effects of different loading conditions on the piston's structural performance and shows how the optimized design can enhance the piston's mechanical properties. The results show that the topology optimization process results in a piston design that reduces weight while maintaining the required strength and performance, thereby enhancing the efficiency of the 3D printing process. The study contributes to the growing body of research on the use of topology optimization in additive manufacturing and provides insights into the practical implementation of this approach in piston design.

Abstract:
The literature abounds with many distinct topology optimisation methods, many of which share common parameter configurations. This study demonstrates that alternative parameter configurations may produce better results than common parameters. Additionally, we try to answer two fundamental questions: identifying the most effective topology optimisation method and determining the optimal parameter selection within this optimisation method. In order to respond to these questions, we conducted a comparative and objective analysis of topology optimisation methods.This paper evaluates four prominent topology optimisation methodologies, SIMP, RAMP, BESO, and LSM, based on three essential criteria: structural strength, topology quality, and computational cost. We conducted an in-depth examination of 12,500 topology optimisation results spanning a broad range of critical parameter values. These outcomes were generated using MATLAB codes. In the meantime, we comprehensively compared our findings with the existing literature on this subject.As predicted, our chosen parameters had a substantial effect on the topology quality, structural strength, and computational cost of the topology optimisation outcomes. Across the 12,500 results, many parameter combinations appeared to produce favourable results compared to conventional parameters commonly found in the existing literature.This study focuses exclusively on four specific topology optimisation methods; however, its findings may be extrapolated to apply to other methodologies. Additionally, while it extensively examines the effects of parameters on topology quality, strength, and computational cost, it does not encompass an exploration of these parameters' impacts on other performance criteria.Novel parameter configurations for topology optimisation have been identified, yielding enhanced outcomes in terms of topology quality, structural strength, and computational efficiency.

Abstract:
Topology Optimisation is a broad concept deemed to encapsulate different processes for computationally determining structural materials optimal layouts. Among such techniques, Discrete Optimisation has a consistent record in Civil and Structural Engineering. In contrast, the Optimisation of Continua recently emerged as a critical asset for fostering the employment of Additive Manufacturing, as one can observe in several other industrial fields. With the purpose of filling the need for a systematic review both on the Topology Optimisation recent applications in structural steel design and on its emerging advances that can be brought from other industrial fields, this article critically analyses scientific publications from the year 2015 to 2020. Over six hundred documents, including Research, Review and Conference articles, added to Research Projects and Patents, attained from different sources were found significant after eligibility verifications and therefore, herein depicted. The discussion focused on Topology Optimisation recent approaches, methods, and fields of application and deepened the analysis of structural steel design and design for Additive Manufacturing. Significant findings can be found in summarising the state-of-the-art in profuse tables, identifying the recent developments and research trends, as well as discussing the path for disseminating Topology Optimisation in steel construction.

Abstract:
Generating accurate digital tree models from scanned environments is invaluable for forestry, agriculture, and other outdoor industries in tasks such as identifying fall hazards, estimating trees’ biomass and calculating traversability. Existing methods for tree reconstruction rely on sparse feature identification to segment a forest into individual trees and generate a branch structure graph, limiting their application to easily separable trees and uniform forests. However, the natural world is a messy place in which trees present with significant heterogeneity and are frequently encroached upon by the surrounding environment. We present a general method for extracting the branch structure of trees from point cloud data, which estimates the structure of trees by adapting the methods of structural topology optimisation to find the optimal material distribution to interpolate the input data. We present the results of this optimisation over a wide variety of scans, and discuss the benefits and drawbacks of this novel approach to tree structure reconstruction. Our method generates detailed and accurate tree structures, with a mean Surface Error (SE) of 15 cm over 13 diverse tree datasets.

Abstract:
Abstract Satellite launches are critical amid increasing demands for advanced services. Rising costs urge innovation in engineering. Enhancing satellite structural integrity during launches is crucial due to intense vibrations. Topology optimisation and additive manufacturing converge as promising solutions. Topology optimisation uses mathematical techniques to iteratively improve structures by reducing mass while enhancing attributes like load capacity. This field, active for about three decades, employs continuum and discrete algorithms to optimise structures. Recent trends show optimised structures through topology optimisation and additive manufacturing promise cost-effective and high-performance solutions. This study aims to extensively review topology optimisation methods, specifically focusing on satellite structures, to shape future developments within the years to come.

Abstract:
L'industrie des télécommunications sans fil fait actuellement face à une croissance considérable pour des débits toujours plus hauts, stimulée par le développement des services mobiles de données. Ce développement rend le spectre disponible de plus en plus rare et nécessite des solutions afin d'optimiser l'usage de ses ressources limitées.Le principal défi auquel les réseaux sans fils font face est de maximiser la disponibilité, la résilience et la qualité de service, tout en minimisant les coûts et en assurant entre les utilisateurs une allocation de ressources équitable. Cette thèse tente de présenter des solutions à ces problèmes et se focalise sur trois thèmes.Sur le premier thème, le but est de trouver la topologie en anneau qui optimise la disponibilité. Il est montré que les algorithmes développés dans le cadre de la théorie des graphes peuvent être utilisés de manière efficace pour définir en temps polynomial la topologie en anneau optimale si les anneaux sont petits (deux nœuds en plus du nœud d'agrégation). Pour les anneaux plus grands, le problème est NP-hard.Le deuxième thème concerne la polarisation. Nous proposons une solution innovante qui peut améliorer efficacité spectrale jusqu'à 50% par comparaison avec l'état de l'art. Le paradigme proposé introduit de nouvelles perspectives au sujet de l'optimisation de la topologie et de l'allocation de canal.Le troisième thème concerne l'allocation de ressources. Nous remettons en question l'approche présente, basée sur l'optimisation de l'efficacité du réseau. Nous montrons que cette approche est similaire au modèle d'utilité espérée de Bernoulli, qui a été réfuté par les paradoxes d'Allais. C'est pourquoi nous introduisons le concept d'aversion au manque d'équité et considérons la question d'allocation de ressources comme un compromis entre efficacité du réseau et équité
The wireless telecommunication sector is presently facing a tremendous growth of demand for higher data rates, driven by the development of mobile data services. This development makes the available spectrum scarcer and scarcer and requires solutions in order to optimize the use of its limited resources.The main challenge wireless networks are facing is to maximize availability, resiliency and Quality of Service, while minimizing costs and ensuring fair resource allocation among users.The present thesis will try to present solutions to these issues and will focus on three topics.On the first topic, the purpose is to find the ring-based topology which optimizes availability. It will be shown that algorithms which have been developed in the field of graph theory can be used efficiently to define in polynomial time the optimal ring network topology if the rings are small (two nodes in addition to the aggregation node). For bigger rings, the problem will be NP-hard. The second topic deals with polarization. We propose an innovative solution which can improve spectral efficiency in wireless ring networks by up to 50% in comparison with the state of the art. The proposed paradigm brings new perspectives regarding topology optimization and channel allocation.The third topic deals with resource allocation. We question the present approach based on optimization of network effciency. We show that this approach is similar to Bernoulli's expected utility model, which has been disproved by Allais' paradoxes. For this reason, we introduce the concept of unfairness aversion and consider the question of resource allocation as a trade-off between network efficiency and fairness

Abstract:
L’équilibrage dynamique est un domaine d’étude important en robotique à grande vitesse et pour la robotique spatiale. La prise en compte des performances d’équilibrage dynamique des robots lors de leur conception permet de réduire les vibrations du bâti, une meilleure précision et des temps de cycle réduits. Dans le but de développer une méthode de conception de robot équilibrés dynamiquement, l’optimisation topologique structurelle est étudiée dans ce travail de recherche en tant qu’outil pour concevoir des robots équilibrés dynamiquement, c’est à dire un robot ne transmettant pas de réaction sur le châssis. La pertinence de la méthodologie proposée est confirmée par la réalisation d’une conception optimisée d’un mécanisme à quatre barres équilibré dynamiquement et l’équilibrage dynamique partiel d’un mécanisme à cinq barres. L’importance de la conception d’un mécanisme à quatre barres équilibré dynamiquement est liée à la possibilité d’exploiter ce mécanisme optimisé comme un module utile à la conception de robots équilibrés dynamiquement. Le mécanisme à cinq barres a une importance toute particulière en raison de ses applications industrielles, où il est généralement utilisé dans des opérations de prise et de dépose
Dynamic balancing is an important field of study in high-speed robotics and spatial robots. Taking into account robot dynamic balancing performance for robot design leads to low base vibrations, high precision and short cycle times. With the aim to develop a comprehensive robot design for dynamic balancing, structural topology optimization is studied in this research work as a tool for designing dynamically balanced robots, also called reactionless robots. The suitability of the proposed methodology is confirmed by accomplishing an optimized design of a reactionless four-bar linkage and the partial dynamic balancing of five-bar robotic mechanism. The significance of the dynamically balanced four-bar linkage is related to the possibility to exploit this optimized linkage as a special leg for building reactionless robots. Besides, the five-bar robot is very important due to its industrial applications, where it is typically used in pick-and-place operations

Abstract:
Dans cette thèse, nous présentons notre étude concernant l'influence de la topologie sur les performances d'apprentissage des réseaux de neurones à topologie complexe. Trois réseaux de neurones différents ont été étudiés : le classique « Self-Organizing Maps » (SOM) avec topologie non-régulière complexe, le « Echo States Network » (ESN) et le « Standard Model Features » (SMF). Dans chaque cas, nous avons commencé par comparer les performances de différentes topologies pour la même tâche. Nous avons ensuite essayé d'optimiser la topologie de certains réseaux de neurones afin d'améliorer ces performances. La première partie traite des Cartes Auto-Organisatrices (SOMs) et la tâche est la classification des chiffres manuscrits de la base de MNIST. Nous montrons que la topologie a un faible impact sur les performances et la robustesse aux défaillances du neurone, du moins pour l'apprentissage à longue durée. La performance peut cependant être améliorée de près de 10% par évolution artificielle de la topologie du réseau. Dans nos conditions expérimentales, les réseaux évolués sont "plus aléatoires" que les réseaux de départ, et affichent une distribution des degrés plus hétérogène. Dans la seconde partie, on propose d'appliquer CMA-ES, la méthode "état de l'art" pour l'optimisation évolutionnaire continue, à l'apprentissage évolutionnaire des paramètres d'un Echo States Network. Sont ainsi optimisés les poids de sortie, bien sûr, mais aussi, le Rayon Spectral et/ou les pentes de la fonction d'activation des neurones). Tout d'abord, un problème standard d'apprentissage supervisé est utilisée pour valider l'approche et la comparer à celle d'origine. Mais la flexibilité de l'optimisation évolutionnaire nous permet d'optimiser non seulement les poids de sortie, mais également, ou alternativement, les autre paramètres des ESN, menant parfois à des résultats améliorés. Le problème classique de l'équilibre du « double pôle » est utilisé pour démontrer la faisabilité de l'apprentissage par renforcement évolutionnaire des ESN. Nous montrons que l'ESN évolutionaire obtient des résultats qui sont comparables à ceux des meilleures méthodes de l'apprentissage de topologie et de l'évolution de neurones. Enfin, la dernière partie présente notre recherche initiale de la SMF - un modèle de reconnaissance d'objets visuels qui est inspirée par le cortex visuel. Deux versions basées sur SMF sont appliquées au problème posé dans un des Challenges PASCAL – Visual multi-Object Challenge (VOC2008). Notre but sur le long terme est de trouver la topologie optimale du modèle SMF, mais le coût de calcul est pour l'instant trop important pour optimiser la topologie complète directement. Dans un premier temps, donc, nous appliquons un algorithme évolutionnaire pour sélectionner automatiquement les caractèristiques utilisés par les systèmes. Nous montrons que, pour le défi VOC2008, avec seulement 20% caractèristiques choisies, le système fonctionne aussi bien qu'avec la totalité des 1000 caractèristiques choisies au hasard
In this dissertation, we present our study regarding the influence of the topology on the learning performances of neural networks with complex topologies. Three different neural networks have been investigated: the classical Self-Organizing Maps (SOM) with complex graph topology, the Echo States Network (ESN) and the Standard Model Features(SMF). In each case, we begin by comparing the performances of different topologies for the same task. We then try to optimize the topology of some neural network in order to improve such performance. The first part deals with Self-Organizing Maps, and the task is the standard classification of handwritten digits from the MNIST database. We show that topology has a small impact on performance and robustness to neuron failures, at least at long learning times. Performance may however be increased by almost 10% by artificial evolution of the network topology. In our experimental conditions, the evolved networks are more random than their parents, but display a more heterogeneous degree distribution. In the second part, we propose to apply CMA-ES, the state-of-the-art method in evolutionary continuous parameter optimization, to the evolutionary learning of the parameters of an Echo State Network (the Readout weights, of course, but also, Spectral Radius, Slopes of the neurons active function). First, a standard supervised learning problem is used to validate the approach and compare it to the original one. But the flexibility of Evolutionary optimization allows us to optimize not only the outgoing weights but also, or alternatively, other ESN parameters, sometimes leading to improved results. The classical double pole balancing control problem is used to demonstrate the feasibility of evolutionary reinforcement learning of ESN. We show that the evolutionary ESN obtain results that are comparable with those of the best topology-learning neuro-evolution methods. Finally, the last part presents our initial research of the SMF - a visual object recognition model which is inspired by the visual cortex. Two version based on SMF are applied to the PASCAL Visual multi-Object recognition Challenge (VOC2008). The long terms goal is to find the optimal topology of the SMF model, but the computation cost is however too expensive to optimize the complete topology directly. So as a first step, we apply an Evolutionary Algorithm to auto-select the feature used by the systems. We show that, for the VOC2008 challenge, with only 20% selected feature, the system can perform as well as with all 1000 randomly selected feature

Abstract:
Bien que de natures différentes, certains réseaux - électriques, thermiques, hydrauliques, mécaniques -possèdent au premier ordre des analogies formelles très fortes, qui permettent le traitement unifié de l'étude de leurs propriétés émergentes - conductivités, modules élastiques. À l'aide d'un principe variationnel, nous avons ainsi dérivé des bornes absolues portant sur ces propriétés, ainsi qu'un ensemble de conditions nécessaires et suffisantes, purement géométriques, pour qu'un réseau quelconque atteigne la borne et soit optimal. Grâce à celles-ci, nous avons trouvé plusieurs nouvelles structures optimales, en deux comme en trois dimensions. Dans une deuxième partie, grâce à un code numérique qui nous a permis aussi de vérifier les résultats précédents, nous avons caractérisé la transition entre mode de flexion et mode de compression qui existait dans un certain type de réseaux, les matériaux fibreux. En relation avec les conditions précédentes, nous avons aussi calculé analytiquement certaines quantités statistiques microscopiques de ces assemblages, qui pourraient servir à la compréhension du phénomène. D'autre part, toujours grâce au programme, nous avons montré dans les réseaux mécaniques que la variation de la raideur aux jonctions amenait à plusieurs transitions, avec des lois de puissance. Enfin, dans une dernière partie, nous avons montré qu'en partant de réseaux proches de l'optimum, on pouvait calculer analytiquement leurs caractéristiques macroscopiques en fonction de l'écart au réseau optimal, et qu'une nouvelle grandeur moyenne basée sur les conditions d'optimalité de la première partie semblait être pertinente pour quantifier cet écart
Some particular networks of very different essences - electrical, thermal, fluidic, mecanic - exhibit, in a first approximation, some strong mathematical analogies, allowing us to conduct a common analysis of their emergent properties - electrical, thermal or fluidic conductivity, and elastic moduli. With a variationnal approach, we established absolute bounds on these quantifies as well as a set of geometrical necessary and sufficient conditions (NSC) to reach them. These conditions lead to new optimal structures, both in two and three dimensions. Thanks to a numerical program, which allowed us to verify these predictions, we then characterized the bending/streching transition which appears in fibrous networks. With the help of the NSC, we computed analytically some statistic, microscopic features of these networks, which might be of importance in the future to understand this phenomenon, as our analyze suggests it. Moreover, we used the programm to investigate the problem of the junctions' energy and showed the presence of several transitions, described by power laws. Finally, we calculated the macroscopic characteristics of some networks close to the optimality, and introduced a new average quantity based on the NSC which seemed to be of importance to quantify this deviation from optimality

Abstract:
L'essor que connaissent les réseaux mobiles a rendu l'automatisation de leur conception incontournable. Cette phase importante du processus de planification des réseaux consiste à localiser des sites sur le terrain, à y positionner des stations et à paramétrer leur configuration. La construction automatique d'un réseau suppose de répondre à des objectifs économiques et techniques. Ceci requiert une modélisation mathématique d'un ensemble de critères pour évaluer la qualité des solutions de réseaux. Jusqu'alors les critères techniques élaborés pour l'optimisation des réseaux sont centrés sur la couverture du réseau, les niveaux d'interférence et l'écoulement du trafic. Des experts radio, qui utilisent des techniques assistées de conception se basant sur la théorie du concept cellulaire, ont évalué les solutions réseaux issues des premières tentatives d'optimisation automatique. Bien que les solutions amélioraient le temps de production et la qualité radio des réseaux, ils ont conclu à la non-faisabilité sur le terrain des solutions proposées faute de structure topologique suffisamment établie. Or la théorie du concept cellulaire définit la topologie du réseau comme un élément central pour garantir la qualité de service et assurer l'extension de la capacité du réseau avec une bonne maîtrise des coûts. Ce mémoire présente plusieurs nouveaux modèles qui intègrent tous les critères géométriques qui s'appuient sur le concept cellulaire théorique et qui visent à structurer le réseau. Ce mémoire met aussi en évidence l'aspect multicritère du problème d'optimisation de la conception des réseaux. Il propose des algorithmes d'optimisation basés sur les approches évolutionnistes
The growth and the complexity of cellular systems aim at the development of optimization procedures for the network design. The network design consists in finding the best sites location and base stations parameters settings. To provide suitable network solutions, the automation requires mathematical formulations of technical and economical objectives. On previous research works, radio coverage, traffic capacity and field overlap were the main factors considered as optimization criteria. These factors brought very good results on network radio performance based on pixel performance analysis. Nevertheless, they led to a poor network organization that i didn't meet the global network performance issued from theorical cellular concept : neighborhood management, cells splitting ability, network densification. . . Experts conclude on non-feasibility of network solutions from automation due to lack of acceptable topological properties. Our work proposes new mathematical models dealing with the network structure based on the theorical cellular concept. These models drive to several formulations of neighborhood and densification which give novel properties to network solutions. We also underline the high importance of multicriteria optimization for these problems. Then we describe evolutionary algorithms for the optimization of site location, station positioning and antenna parameter settings. And we give some results on real-life networks for the antenna parameters settings problem and compared them to previous approaches

Abstract:
Un réseau de capteurs sans fil résulte du déploiement d'un ensemble de petites unités autonomes interagissant via un réseau construit grâce à leur module de communication qui observent leur environnement par des capteurs pour ensuite traiter et/ou sauvegarder cette information via leur capacité calculatoire et de stockage. La couverture est la seule représentation disponible aux réseaux de capteurs de l'espace physique environnant. Par conséquent, il est essentiel de pouvoir qualifier et quantifier sa qualité notamment concernant la présence de trous. Nos travaux utilisent la topologie algébrique pour répondre à ces problèmes. Plus précisément, nous définissons dans un premier temps une notion de trou de couverture d'un champ scalaire qui mesure la qualité de l'estimation par le réseau de capteurs sans pour autant connaître la position des capteurs. Cela permet d'utiliser l'homologie simpliciale pour déterminer la qualité de la couverture globale et accessoirement de mettre en veille certains capteurs surnuméraires tout en garantissant la couverture. Puis, afin de rendre le résultat précédent facilement calculable par un réseau de capteurs grâce à une distribution du calcul qui supporte en plus le passage à l'échelle, nous utilisons la théorie de Morse discrète pour faire le calcul des groupes d'homologie nécessaires à notre application précédente. Enfin, cette dernière approche est rendue suffisamment souple pour permettre le suivi temporel des modifications de la couverture de manière délocalisée. Cela permet non seulement de suivre la qualité de la couverture lorsque l'environnement se modifie mais aussi de proposer un schéma distribué de mise en veille des capteurs afin d'augmenter la durée de vie du réseau de capteurs tout en garantissant une couverture suffisante
A wireless sensor network consists of a set of small autonomous units that interact via a network built by their communication modules. They observe their environment by their sensors and then they manage this information according to their computational capacity and storage. The coverage is the only representation available to the sensor network of its environment. Therefore, it is essential to quantify the quality of coverage especially related to the presence of holes. Our work uses algebraic topology to solve these problems. We first define a notion of the coverage hole in a scalar field, which measures the quality of the estimation by the sensor network without knowing the positions of the sensors. It allows the simplicial homology tool to determine the quality of the overall coverage and put certain redundant sensors into sleeping mode with the guarantee of the coverage. Then, to make the previous result easier to compute by a sensor network, the discrete Morse theory is used. It allows a distributed computation of the previous homology groups while supporting scalability necessary in sensor networks domain. Finally, one flexible approach that allows time varying tracking which allows a coverage is proposed in a distributed way. When the environment changes, this approach can not only guarantee the capability of monitoring of coverage quality, but also proposes a scheme to send to sleep the redundant sensors in order to increase the lifetime of the sensor network with adequate coverage

Abstract:
En optimisation de formes, de nombreux résultats ont déjà été obtenus dans le cas de domaines à frontière régulière et pour des perturbations régulières de ces domaines. Par contre, l’étude de domaines non-réguliers, tels que des domaines fissurés par exemple, et l’étude de perturbations singulières telles que la création d’un trou dans un domaine est plus récente et plus complexe. Ce nouveau domaine de recherche est motivé par de multiples applications, car en pratique, les hypothèses de régularité ne sont pas toujours vérifiées. Les outils tels que la dérivée topologique permettent d’appréhender ces perturbations singulières de domaines et leur utilisation est maintenant fréquente. Dans la première partie, nous étudions la structure de la dérivée de forme pour des domaines fissurés. Dans le cas d’un ouvert régulier, de classe C1 ou lipschitzien par exemple, la dérivée dépend uniquement des perturbations de la frontière du domaine en direction de la normale. Ce théorème de structure n’est plus valable pour des domaines contenant des fissures. On généralise ici ce théorème de structure aux domaines fissurés en dimension quelconque pour les dérivées premières et secondes. En dimension deux, on retrouve le résultat usuel, à savoir qu’en plus du terme classique, deux nouvelles contributions apparaissent dûes aux extrémités de la fissure. En dimension supérieure, un nouveau terme apparaît en plus du terme classique, dû à la frontière de la variété à bord représentant la fissure. Dans la deuxième partie, nous étudions la perturbation singulière d’un domaine et nous modélisons cette perturbation à l’aide d’extensions auto-adjointes d’opérateurs. Nous décrivons cette modélisation, puis nous montrons comment elle peut être utilisée pour un problème d’optimisation de forme. En définissant une fonctionnelle d’énergie approchée pour ce problème modèle, on retrouve notamment la formule de la dérivée topologique usuelle. Dans la troisième partie, on propose une application numérique de la dérivée topologique et de la dérivée de forme pour un problème non-linéaire. On cherche à maximiser l’énergie associée à la solution d’un problème de Signorini dans un domaine ­. L’évolution du domaine est représentée à l’aide d’une méthode levelset
In shape optimization, the main results concerning the case of domains with smooth boundaries and smooth perturbations of these domains are well-known, whereas the study of non-smooth domains, such as domains with cracks for instance, and the study of singular perturbations such as the creation of a hole in a domain is more recent and complex. This new field of research is motivated by multiple applications, since the smoothness assumptions are not fulfilled in the general case. These singular perturbations can be handled now with new and efficient tools like topological derivative. In the first part, the structure of the shape derivative for domains with cracks is studied. In the case of a smooth domain, with boundary of class C1 or lipschitzian for instance, the derivative depends only on the perturbations of the boundary of the domain in the normal direction. This structure theorem is no longer valid for domains with cracks. We extend here the structure theorem to domains with cracks in any dimension for the first and second derivatives. In dimension two, we get the usual result, i. E. The shape derivative depends also on the tangential components of the deformation at the tips of the crack. In higher dimension, a new term appears in addition to the classical one, coming from the boundary of the manifold representing the crack. In the second part, the singular perturbation of a domain is approximated by using self adjoint extensions of operators. This approximation is first described, then it is applied to a shape optimization problem. An approximated energy functional can be defined for this model problem, and we obtain in particular the usual formula of the topological derivative. In the third part, a numerical application of the topological and shape derivatives is proposed for a non-linear problem. The problem consists in maximizing the energy associated to a Signorini problem in a domain ­. The evolution of the domain is done with the help of a levelset method to handle easily topological changes

Abstract:
Nous abordons l'optimisation topologique des coques dont l'épaisseur est continument variable, dans le cadre des nouveaux outils de la phase préliminaire de conception. Une difficulté majeure des problèmes de topologie concerne leur formulation : nous formulons le problème de recherche des pièces de masse minimale sous restrictions géométriques et structurales, proche des situations industrielles. Pour des restrictions de type vibratoire, une formulation basée sur les fréquences des modes concernés est définie. La modélisation adoptée est compatible avec les modèles de coque : la région de conception est décrite par une épaisseur maximale associée à une surface moyenne imposée. Le problème d'optimisation se ramène alors à la détermination d'une distribution d'épaisseur associée à cette surface : la pièce (resp. Les trous) correspond aux régions d'épaisseur positive (resp. Nulles). La discrétisation nécessaire a une bonne résolution géométrique implique un grand nombre de paramètres, ce qui constitue une difficulté. Elle fait également apparaitre un grand nombre de limitations pour les contraintes mécaniques de mises. Nous dissocions alors le problème d'optimisation soumis à ces limitations de celui restreint aux autres limitations structurales (peu nombreuses). Pour le premier de ces problèmes, un critère d'optimalité sans sensibilité analogue au fully stressed design est utilisé. Pour le second problème, le dual du problème approximé conduit à une méthode générale de programmation séquentielle explicite. En outre, nous proposons une méthode de désassemblage adaptée à l'analyse des structures paramétrées. Nous illustrons par quelques exemples industriels que le modèle et les méthodes numériques développés s'accordent pour donner un outil rapide de détermination de la topologie.

Abstract:
Cette thèse aborde la problématique du recalage non rigide d'images cérébrales tridimensionnelles inter-patients. Le modèle de déformation considéré repose sur une représentation paramétrique multiéchelle dans une base de fonctions B-splines, dont les paramètres sont estimés par minimisation d'une fonctionnelle d'énergie basée sur la différence des intensités (cas monomodal). La contribution principale de ce travail est de garantir à la transformation estimée de préserver l'intégrité des structures déformées dans le cas 3D. Cette propriété, dite de conservation de la topologie, requiert d'imposer la positivité du jacobien de la transformation sur le domaine continu sous-jacent de l'image. Le problème d'optimisation sous contraintes correspondant est résolu grâce à des techniques issues de l'analyse par intervalles. Ce travail aborde par ailleurs différents aspects du recalage, à savoir le choix du critère de similarité et sa symétrisation, la régularisation du champ de déformation et la normalisation des intensités entre deux images. Une méthode originale de normalisation des intensités est proposée, basée sur l'estimation d'un mélange de lois gaussiennes à partir de l'histogramme conjoint. Cette méthode, dans un premier temps conçue pour lever des difficultés rencontrées dans le cadre du recalage d'images monomodales, a permis d'étendre la méthode au cas d'images IRM de pondérations différentes. Enfin, la mise en place d'un cadre de validation a permis d'évaluer l'influence des différents paramètres de la méthode et d'effectuer des comparaisons avec d'autres méthodes de recalage (recalage affine et l'algorithme des démons)
This dissertation deals with non-rigid registration of 3D inter-patient cerebral images. The deformation model considered is based on a hierarchical parametric representation using B-spline basis functions, the parameters being estimated by minimizing a cost function relying on the intensity difference between images (monomodal case). The main contribution of this work is to warrant the estimated transformation to preserve the integrity of warped structures in the 3D case. This property, called topology preservation, is ensured by imposing the positivity of the jacobian of the transformation on the underlying continuous domain of the image. This constrained optimization problem is solved by resorting to interval analysis techniques. Furthermore, other aspects of the registration problem are considered, namely the choice of the similarity criterion and its symmetrization, the regularization of the deformation field and the intensity normalization between images. An original intensity normalization procedure, based on the estimation of a Gaussian mixture model of the joint histogram, is presented. This method, initially proposed to overcome some problems encountered with monomodal image registration, has been extended to the registration of multimodal MRI images. Finally, a validation framework is devised in order to evaluate the influence of the different parameters of the method and to carry out comparisons with other registration methods (affine registration and the demons algorithm)

Abstract:
Abstract This work presents the aerodynamic topology optimisation of high pressure turbine rotor blade tips. Before carrying out the topology optimisation on the blade tip, some initial tip design studies were carried out. The winglet shape was optimised using two different design space setups and parameter limits. The optimum winglet design features the largest overhangs and in the case of unconstrained optimisation proved to have 1.40% greater aerodynamic efficiency. Secondly, a radial basis function based parametrisation was set up to allow the creation of single squealer line using the flat tip blade as a baseline geometry. The optimum case proved to increase efficiency 0.46% compared to the flat tip. After that, a combination of winglet and topology free squealer tips was investigated for topology optimisation. The winglet tip was parametrized as in the winglet only optimisation cases and topology free squealer walls were created using mapping of radial basis function surfaces of different complexities. It is shown that by combining both winglet and novel squealer topology optimisation, better designs of different topologies can be produced.

Abstract:
A binary encoding method for bond graphs that can be used for genetic algorithms (GAs) applications is presented. The originality of the proposed coding is that it encompasses causal information. This ensures that causal analysis is taken into account in assessing the fitness of topologies generated in GA operations and the suitability of design candidates to meet performance specifications can be tested directly from the binary code as the model equations can be derived from it. The code is suitable for GAs applications on bond graphs (BG) for topology and parameter optimisation in automated synthesis of dynamic systems. The coding method and its possible applications are illustrated through worked examples.

Abstract:
With the development of the cloud offers, we observe a prominent trend of applications being migrated from private infrastructure to the cloud. Depending on the application’s complexity, the migration can be complex and needs to consider several dimensions, such as dependency issues, service continuity, and the service level agreement (SLA). Amadeus, the travel industry leader, had partnered with Microsoft to migrate its IT ecosystem to the Azure cloud. This work addresses the specificity of cloud-to-cloud migration and the multi-cloud constraints. In this paper, we summarise the Amadeus Migration process. The process aims to drive the migration from an initial private cloud environment to a target environment that can be a public or hybrid cloud. Further, the process focuses on a prediction phase that guides the migration process. This paper expects to provide an efficient decision-making process that guides managers and architects to optimise and secure their migration process while considering micro-servicesoriented applications targeting an efficient deployment over multi-cloud or hybrid cloud. The prediction relies on the network simulation to predict applications’ behaviour in the cloud and evaluate different scenarios and deployment topologies beforehand. The objective is to predict migrated applications’ behaviour and identify any issue related to the performance, the application’s dependency on other components, or the deployment in the cloud. The migration process proposed in this paper relies on SimGrid, a toolkit developed by INRIA[52] for distributed application modelling. This framework offers a generic process to model IT infrastructure and can assist cloud-to-cloud migration. Specific attention is given to predictive and reactive optimisations. The first results show predictive optimisation's impact on securing KPI and reactive optimisation to optimise the solution cost. Thus, we reach an average cost reduction of 40% in comparaison with the same deployment strategy while keeping the same SLA.

Abstract:
Abstract In turbomachinery, components are pushed to their limits to meet more stringent specifications in order to increase their performances. In this context, structural topology optimisation is a promising technology as it improves substantially the mechanical properties while drastically reducing the mass. With the coming of additive manufacturing, optimised geometry can be manufactured making this technology even more attractive. The aim of this work is to investigate the potential of topology optimisation to optimise a full bladed disc to improve its dynamic performances in terms of mass, stress and modal coincidences. The topology of a 3D-Finite Element Model of an academic bladed disc is optimised in this work and experimental validation is expected. So first, the disc is designed to fit in the test-rig and the mechanical integrity of the 3D-printed disc is experimentally verified. Second, the topology of the blades is optimised. Based on a trial-and-error process, the appropriate topology optimisation problem properties for vibration optimisation are identified. Thus, adding a static force at the blade tip forces a better material distribution over the domain and increases the blade stiffness. To minimise the number of coincidences, a numerical strategy based on iterative topology optimisation simulations is proposed to identify the correct set of frequential constraints. Final results show that the mass of the blade is reduced up to 32% and the number of frequential coincidences is reduced from 11 to 4. Final geometries are 3D-printed and mounted on the disc.

Abstract:
Abstract This paper will describe the analysis, optimisation and subsequent implementation of an electrical protection system utilised on a subsea Electrically Heat-Traced Flowline system (EHTF) using conventional topsides power protection equipment deployed in a novel topology. It will also discuss the project-imposed challenge of protecting an electrical subsea system of significant length from only a single feeder protection whilst keeping it simple, sensitive, rapid, and covering 100% of the long heating cable length. The paper will describe the detailed electrical analysis methods deployed, the additional electrical verification carried out and the decision-making processes and drivers choice used during an electrical system design optimisation challenge that was conducted in a short timeframe and planned around operational assets. The close collaboration between contractor, client, vendors and third-party expertise was fundamental to solve successfully the challenges and mitigate the overall risks. Key engineering processes described: Subsea Umbilical Riser and Flowline (SURF)/Topside interface management / interface meetings, design review process, use of interim design reviews, the decision scoring matrix, the go/no go risk assessments, pre-commissioning, commissioning, performance test. The benefits and drawbacks of the different electrical topologies investigated will be reported, specifically the retention of an isolated neutral system. The paper will provide the final chosen protection topology and the results of the individual component testing. A key observation to report being that when technology is new, the need to validate the implementation of it must be included in the initial design. There must be added monitoring even if it’s not thought to be essential at start of a project, even if it’s considered as "sugar coating" a design or adding complexity, there can be huge benefits on new technology deployment. The paper will report on the observed benefits of site integration testing versus individual routine / factory acceptance testing when deploying TRL7 items in novel topologies. The final commissioning results will be reported and an engineer’s view of a journey from concept to final commissioning will be presented. Existing literature is limited on electrical topology on subsea infrastructures and thus this paper enhances the industry knowledge base. The paper describes a novel topside protection system for subsea ground isolated loads. As the subsea industry turns towards electrification, it is essential that lessons are learned. This ensures novel solutions can be deployed provided a correct design verification process. The paper could trigger discussions around a new best practice recommendation about the interface topsides/subsea electrical infrastructures.
