Résumé :

An active damping design technique based on single input velocity feedback is presented in this paper. The stability conditions for each individual mode in SISO and SIMO velocity feedback are demonstrated. Since these stability conditions are derived using modal information, it is appropriate to incorporate this technique with the commonly used dynamic analysis techniques, such as experimental modal analysis and finite element analysis, for active damping design. Based on these stability conditions, two active damping design algorithms are proposed: 1) Constrained Least Squares Feedback Gain Computation, and 2) Optimal Feedback Gain Computation With Flexible Damping Factors. The first algorithm is a straightforward method to find the feedback vector for the given damping factors and the modal frequencies. The second algorithm is based on an optimization process which allows freedom in chosing the desired damping factors. The problem of locating the actuator and sensors is also discussed in this paper. The stability theory and active damping design technique are verified by an experimental example.

Résumé :

The verb agreement systems of Jinghpaw, Meyor, Northern Naga, and Northeast, Northwest and Southern Kuki-Chin contain material which is demonstrably inherited from Proto-Trans-Himalayan. Here we discuss morphological evidence that these systems share a common ancestor more recent than PTH. There is strong evidence connecting Jinghpaw with both Northern Naga and Kuki-Chin, and weaker evidence directly linking Northern Naga and Kuki-Chin, and both of these with Meyor. This is evidence that all of these languages belong to a single branch of the family, an idea which has been suggested in the past but never argued for. Les systèmes d’accord verbaux des langues jinghpaw, meyor, naga du nord, et kuki-chin incluent des formes dont on peut démontrer l’origine proto-trans-himalayenne. Cet article présente des preuves morphologiques qui démontrent que ces systèmes descendent d’un paradigme ancestral plus récent que le proto-trans-himalayen. Les caractéristiques morphologiques communes entre jinghpaw et naga du nord sont très claires, et l’on trouve également des liens rapprochant le naga du nord avec le kuki-chin, et ces deux groupes avec le meyor. On propose que toutes ces langues appartiennent à une branche unique de la famille trans-himalayenne, une idée qui a été suggérée dans des publications antérieures mais jamais développée de façon argumentée.

Résumé :

La fin du XVIe et le début du XVIIe siècle marquent un développement sans précédent de la consommation de sucre en Europe et un essor de son industrie dans le Nouveau Monde. L'exploitation de la canne qui, au cours du XVIe siècle, était passée du bassin méditerranéen aux Iles de l'Atlantique comme Madère, Sâo Tome ou les Canaries, trouva sa pleine expression en terres américaines peu après leur découverte en 1492. Le Brésil devint au XVIe siècle le premier producteur de sucre du monde. On connaît les péripéties de la conquête du Nouveau Monde accouchant d'immenses plantations de sucre dont le mode de production esclavagiste constitue l'un des modèles d'application du système capitaliste, comme le montre Sydney Mintz dans son beau livre Sweetness and Power.

Résumé :

Cette thèse décrit l'application de techniques connexionnistes à l'identification de systèmes siso non linéaires. L'établissement de modèles de comportement des systèmes linéaires et non linéaires en vue de leur conduite est un domaine incontournable en automatique. Les systèmes linéaires ne représentent le plus souvent qu'une approximation sur un domaine réduit de systèmes intrinsèquement non linéaires. Nous nous intéressons, ainsi, à l'identification de systèmes non linéaires en privilégiant un domaine de recherche: les réseaux de neurones multicouches. Les capacités d'approximation de systèmes non linéaires constituent l'atout majeur des réseaux de neurones. Nous transposons les techniques élaborées pour les systèmes linéaires dans le domaine de l'automatique aux systèmes non linéaires en faisant appel aux réseaux de neurones multicouches, afin de construire des modèles neuronaux. A travers différentes études, réalisées pour des systèmes linéaires et non linéaires, nous montrons qu'un lien étroit existe entre les méthodes classiques d'identification des modèles paramétriques discrets et les méthodes neuronales tant au niveau des techniques d'estimation des paramètres qu'au niveau de l'identification structurelle. A partir de différents algorithmes d'estimation, nous élaborons une démarche d'identification qui permet de déterminer la structure du modèle neuronal, c'est-à-dire d'évaluer le retard pur, d'estimer les ordres du système et d'optimiser le nombre de neurones dans la couche cachée

Résumé :

Les télécommunications sans fil mobiles connaissent un intérêt croissant depuis plus d'une décennie. Elles se décomposent en deux types d'applications : la téléphonie et les réseaux informatiques. La complémentarité de ces deux technologies offre un potentiel énorme pour fournir aux usagers une mobilité sans interruption de service quand l'utilisateur passe du domaine public au domaine privé et réciproquement.

Toutefois, quel que soit le système de communication sans fil envisagé, il est soumis à une contrainte forte associée au caractère multitrajets du canal de propagation. Celles-ci se traduisent par des évanouissements parfois profonds et rapides du niveau de réception et par la sélectivité en fréquence du canal. Ainsi, le phénomène de trajets multiples associé au canal radioélectrique engendre des perturbations lors de la transmission de signaux à un instant, une position et une fréquence donnée.

L'objectif de cette thèse s'inscrit dans ce contexte puisqu'il porte sur la caractérisation spatio-temporelle du canal de propagation tenant compte d'une ou plusieurs antennes à l'émission comme à la réception.

Ainsi, dans ce document sont définis les outils théoriques permettant le calcul des fonctions caractéristiques. Ce formalisme est alors intégré dans un logiciel de caractérisation spatio-temporelle, pouvant considérer en entrée des données issues de campagnes de mesures ou provenant de modèles de propagation. Enfin, il propose une ouverture vers l'utilisation des informations de caractérisation du canal dans un système HiperLAN/2.

Résumé :

Ce mémoire aborde l'analyse et le traitement de données biomédicales. L'objectif est d'extraire des informations nécessaires au diagnostic de certaines pathologies. Plus précisément, ce rapport de thèse peut être scindé en deux parties. La première concerne l'élaboration d'un système ambulatoire multi-varié qui permette d'explorer les fonctions neurologiques nécessaires au diagnostic de différents troubles du sommeil. Des méthodes de séparation aveugle de sources, développées pour des mélanges instantanés, ont été étudiées et appliquées pour répondre à ce problème. La seconde partie porte sur l'étude du système nerveux autonome. Le but est de caractériser le profile sympathique et parasympathique des patients. Face aux différents problèmes mathématiques rencontrés, nous avons élaboré de nouvelles méthodes d'estimation de phase. Ces dernières ont fait l'objet d'une étude comparative au travers de simulations numériques.

Resumo: Esta dissertação teve como motivação inicial a busca de uma abordagem unificada para o problema de equalização não-supervisionada, a ser aplicada às configurações SISO, SIMO e MIMO. Tal abordagem se refere a dois aspectos fundamentais do problema: a estrutura do equalizador e a otimização de seus parâmetros. Desta forma, propomos uma mesma metodologia para estudar, nas três configurações citadas, o que denominamos de limitação estrutural e de limitação de critério. A primeira é caracterizada pela impossibilidade de inversão perfeita do canal fazendo uso de apenas filtros com resposta impulsiva finita (FIR); a segunda se refere às limitações quanto ao uso de estatísticas de ordem dois (EO2) para a obtenção do equalizador ótimo no caso não-supervisionado. Para tal análise, reunimos resultados um tanto dispersos na literatura para formalizar de maneira unificada e acessível os conceitos de sistema inversível e de sistema de fase mínima para as três configurações. Em seguida, empregamos o conceito de filtro de erro de predição linear para estudar o uso de EO2 em equalização, estendendo esse conceito também às três configurações
Abstract: This dissertation was motivated by the idea of developing a unified approach to the problem of unsupervised equalization, in the context of SISO, SIMO and MIMO channels. This approach is concerned with two fundamental aspects of the equalization problem: the structure of the equalizer and the optimization of its parameters. In this sense, we propose a same methodology to study, in the three aforementioned scenarios, two different limitations. The first one, which we denote structural limitation, is related to the impossibility of inverting any channel employing only finite impulse response (FIR) filters. The second one, which we call criterion limitation, refers to the limitation regarding the use of second order statistics (SOS) to obtain the equalizer in an unsupervised manner. In order to perform this analysis, we collected results that are rather scattered in the literature to formalize the concepts of invertible and minimum-phase systems in all three scenarios. Then, we use the concept of a prediction-error filter to study the limitation of SOS in the equalization problem

Résumé :

Au cours des vingt dernières années, le débit croissant des communications radiofréquences a imposé la mise en œuvre de techniques d'égalisation de plus en plus complexes. Pour résoudre ce problème, les modulations multi-porteuses ont été massivement employées dans les standards de communications à très haut débit. Un exemple caractéristique de la démocratisation de ces formes d'ondes est l'utilisation de l'OFDM (Orthogonal Frequency Division Multiplexing) sur le lien descendant des réseaux 4G. Toutefois, pour les futurs réseaux 5G, l'émergence prévue des communications M2M (Machine-to-Machine) impose aux formes d'ondes une grande tolérance aux asynchronismes au sein de ces réseaux et ne permet pas l'emploi de l'OFDM qui nécessite une synchronisation stricte en temps et en fréquence. Egalement, l'utilisation efficace du spectre par les techniques de la radio cognitive est incompatible avec l'OFDM en raison de la mauvaise localisation en fréquence de cette forme d'onde.Dans ce contexte, la forme d'onde FBMC-OQAM (Filter Bank Multi-Carrier - Offset Quadrature Amplitude Modulation) est apparue comme une solution potentielle à ces problèmes. Toutefois, l'égalisation des signaux FBMC-OQAM en canal sélectif en fréquence et/ou canal MIMO (Multiple Input Multiple Output) est rendue difficile par la subsistance d'interférences entre les sous-porteuses du schéma FBMC-OQAM. Cette thèse étudie donc l'égalisation de ces liaisons. L'étude de récepteurs WL (Widely Linear) qui permettent la suppression d'interférences, sans diversité d'antenne en réception, au sein des réseaux utilisant des signaux noncirculaires au second ordre (e.g. signaux ASK, GMSK, OQAM) est privilégiée. Cette technique nommée SAIC (Single Antenna Interference Cancellation) et utilisée dans les réseaux GSM pour la suppression d'interférences co-canal est envisagée pour une extension à la suppression des interférences entre porteuses des formes d'ondes FBMC-OQAM. La technologie SAIC, qui a été étendue pour plusieurs antennes en réception (MAIC - Multiple Antenna Interference Cancellation) a l'avantage de sa faible complexité et ne génère pas de propagation d'erreur à faible SNR contrairement aux solutions de suppression successive d'interférences. Une approche progressive est adoptée, depuis l'élaboration du SAIC pour la suppression d'interférences co-canal où nous démontrons l'importance de considérer le caractère cyclostationnaire des signaux OQAM. Basée sur cette constatation, une nouvelle structure de réception utilisant un filtre WL-FRESH (FREquency-SHift) est proposée et ses meilleures performances comparé au récepteur WL standard sont présentées analytiquement et par simulations numériques. L'extension du SAIC pour la suppression d'une interférence décalée en fréquence est ensuite menée et différentes structures de réception sont proposées et analysées en détail. L'aptitude des traitements SAIC utilisant des filtres WL-FRESH à supprimer 2 interférences décalées en fréquence est présentée. Dans le contexte des signaux FBMC-OQAM qui utilisent généralement le filtre de mise en forme PHYDYAS, chaque sous-porteuse est polluée par ses deux sous-porteuses adjacentes. Cependant, pour évaluer les traitements SAIC sans devoir prendre en compte la contribution des sous-porteuses voisines à ces sous-porteuses adjacentes, un filtre doit précéder le traitement de réception. Pour cette raison, l'analyse de l'impact d'un filtre de réception sur les performances des traitements SAIC proposés est effectuée et les conditions sur la bande passante du filtre nécessaires pour justifier l'intérêt d'un traitement SAIC par filtrage WL sont présentées. Dans un dernier temps, une approche alternative d'égalisation des signaux FBMC-OQAM est présentée. Elle consiste à démoduler conjointement les sous-porteuses interférentes après filtrage. Cette technique est abordée dans le contexte de liaisons MIMO Alamouti FBMC-OQAM
During the last two decades, the increase of wireless communications throughput has necessitated more and more complex equalization techniques. To solve this issue, multicarrier modulations have been massively adopted in high data rates wireless communications standards. A typical example of the wide use of these waveforms is the adoption of OFDM (Orthogonal Frequency Division Multiplexing) for the downlink of 4G mobile networks. However, for next-generation 5G networks, the expected increase of M2M (Machine-to-Machine) communications forbids the use of OFDM because of the tight time and frequency synchronization constraints imposed by this waveform. Additionally, efficient spectrum occupation through cognitive radio strategies are incompatible with the poor spectral localization of OFDM. In this context, FBMC-OQAM (Filter Bank Multi-Carrier - Offset Quadrature Amplitude Modulation) waveforms appeared as a potential solution to these issues. However, equalization of FBMC-OQAM in frequency selective channels and/or MIMO (Multiple Input Multiple Output) channels is not straightforward because of residual intrinsic interferences between FBMC-OQAM subcarriers. Thus, this thesis considers equalization techniques for these links. In particular, the study of WL (Widely Linear) receivers allowing the mitigation of interferences, with only a single antenna, among networks using second-order noncircular waveforms (e.g. ASK, GMSK, OQAM signals) is privileged. This work studied this technique, named SAIC (Single Antenna Interference Cancellation) and applied for the suppression of co-channel interferences in GSM networks in order to adapt it for the cancellation of FBMC-OQAM intercarrier interferences. SAIC, which was further extended to multiple receive antennas (MAIC - Multiple Antenna Interference Cancellation) benefits from its low complexity and does not generate error propagation at low SNR contrary to successive interference cancellation based solutions. A progressive approach is adopted, from SAIC/MAIC for the suppression of co-channel interferences where we emphasize the importance of considering the cyclostationary nature of OQAM communication signals. Based on this, the proposal of a new WL-FRESH (FREquency-SHift) filter based receiver for OQAM-like signals is made and its performance is characterized analytically and by numerical simulations asserting its superior performance with respect to the standard WL receiver. The extension of SAIC/MAIC for the mitigation of a frequency-shifted interference is then considered and reception structures are proposed and analyzed in detail. The ability of WL-FRESH filter based SAIC receivers to perform the suppression of multiple frequency-shifted interferences is assessed. In the context of FBMC-OQAM signals which frequently utilize the PHYDYAS pulse-shaping prototype filter, each subcarrier is polluted only by its adjacent subcarriers. However, to evaluate SAIC processing without having to consider neighboring subcarriers of the adjacent ones, a filtering operation prior to the SAIC processing is needed. For this reason, the impact of a reception filter on the performance gain provided by the SAIC processing was conducted and conditions on the filter bandwidth have been established which governs the potential performance gain of a WL filter based processing for SAIC of frequency-shifted interferences.In a last step, an alternative equalization approach for FBMC-OQAM is investigated. This proposed technique consists in the per-subcarrier joint demodulation of the subcarrier of interest and its interfering adjacent ones after a filtering step. This proposal is considered in the context of MIMO Alamouti FBMC-OQAM links

Résumé :

A Identificação de Sistemas é uma das técnicas utilizadas para se obter a representação matemática de um sistema. Diversos métodos podem ser aplicados para se obter um modelo matemático através da identificação de sistemas, entre eles o método de identificação assintótico, também chamado de ASYM (Zhu, 1998). Este trabalho propõe aplicar o método de identificação assintótico em sistemas SISO para a obtenção de modelo de sistemas ditos caixa-preta e avaliar o seu desempenho buscando também o melhor detalhamento do método. Os modelos obtidos foram avaliados de acordo com sua nota calculada através do método ASYM, através da comparação do índice de ajuste fit para autovalidação e validação cruzada e pela variância dos parâmetros dos modelos. O método ASYM é exaustivamente testado para sua avaliação. Entre os testes realizados neste trabalho destacam-se dois experimentos tipo Monte-Carlo com mais de quinhentas identificações e a aplicação do método em uma planta real. Os testes comprovaram a viabilidade da aplicação do método assintótico na identificação de sistemas SISO do tipo caixa-preta com excelente desempenho para estruturas ARMAX.
System Identification is one of the techniques used to obtain the mathematical representation of a system. Several methods can be applied to obtain a mathematical model by the system identification, including the asymptotic method, also called ASYM (Zhu, 1998). This work proposes to apply the ASYM method for SISO systems identification, then obtain models of black-box systems called \"black box\" and evaluate its performance and show details of the method. The models obtained were evaluated according to their grade calculated using the ASYM method, by comparing the fit adjustment index, self-validation and cross validation and the variance of model parameters. The asymptotic method has been extensively tested to be evaluated. Among the tests in this work, two stand out such Monte Carlo experiments with more than five hundred identifications and a real plant identification. The tests proved the feasibility of applying the asymptotic method in the \"black box\" SISO systems identification with excellent performance for ARMAX structures.

Résumé :

The improvement of SISP practices has rapidly become one of the most critical issues facing many organisations, including banks. Globally, the banking sectors, including the Saudi one, have developed and implemented many IS strategies. Several systems have been executed to support the countries’ economies which have benefited from the increased trading resulting from the greater flexibility in time and costs associated with banking transactions. To continue these achievements and to improve SISP processes, several factors require careful investigation based on their relationship to SISP success; which include SISP objectives, SISP internal factors, external consultant functions, SISP external factors, measurements of SISP success, key stakeholders’ roles, and triggers. Therefore this study investigates the impact of these factors on SISP success. Data were collected in three phases. Phase 1 was an initial study with one or two interviews with the IT directors of each bank in the Saudi banking sector comprising the central bank and 11 commercial banks. The outcomes informed the development of a survey that was used in Phase 2; to investigate a sample containing a central bank, a domestic commercial bank and a domestic-foreign commercial bank to determine their SISP processes. 157 completed questionnaires were returned from the bank executives, business and IT directors and consultants. In Phase 3, 57 interviews confirmed and explained the quantitative results from Phase 2. Therefore, an in-depth case study was made in the three banks during Phases 2 and 3. The research results support previous findings on the SISP’s seventeen objectives collected by several researchers across different industries and in various countries. Furthermore, the research condenses these seventeen objectives into five more practical and achievable objectives for the banking sector. These are: 1) planning and deployment of information systems; 2) leading organisation changes; 3) improving stakeholders’ involvement and communication; 4) achieving the strategic priorities; and 5) alignment of organisational policies and architecture for business and IS. In addition, the findings identify the factors according to their relationship with SISP success and therefore explore several elements with positive, negative or no impact on SISP success in the banking sector. The thesis presents conclusions and suggests areas for further research.

Résumé :

A decentralized adaptive neural controller (DANC) for active vehicle suspension systems using singular perturbation method is developed in this paper. In order to reduce the neural network (NN) weight’s number, the DANC is designed based on the decentralized single input single output (SISO) NN. The active suspension system SIMO characteristic is decoupled into two time-scale separated SISO systems via the singular perturbation technique for achieving a compromise between riding comfort and handing performance. The structure of this MIMO model-free controller is derived from the Lyapunov stability theory to monitor the system for tracking a user-defined reference model. The experimental results are discussed and compared with that of the passive suspension.

Résumé :

Active suspension has been widely studied in recent decades but the implementation of the single-input, single-output (SISO) force-control architecture that many of the prior studies use has had limited success due to the lightly damped zeros. The inherent trade-off between robust stability and road disturbance attenuation for SISO control architecture is the main culprit. In this paper, we study whether the single-input, two-output (SITO) control architecture provides sufficient degrees of freedom in the control synthesis. First, a quarter car model with an electromagnetic motor is derived and the improved LQG/LTR design technique is employed to simultaneously recover both stability robustness and disturbance attenuation properties at the expense of measurement noise sensitivity. It was found that if the control system is restricted to SISO architecture, sprung mass acceleration is the most promising choice among practical measurements. Both classical and modern control approaches are used to analyze the effectiveness of the proposed method and its closed-loop performance. Simulation results show that stability robustness and disturbance attenuation can be dramatically improved by the SITO architecture over its SISO counterpart.

Résumé :

CRONE control, robust control methodology based on fractional differentiation, is applied to state observer design. State observation can indeed be viewed as a regulation problem given that the goal of a state observer is to cancel the observation error in spite of measurement noise, disturbances and plant perturbations. This conclusion has been used recently to define a new class of state observers known in the literature as “dynamic observers” or “input-output observer”. It is based on the observation error dynamic feedback. In this paper, this idea is used to define the CRONE observer design methodology for nonlinear SISO systems. As for CRONE control, fractional differentiation in the definition of an equivalent open loop transfer function permits the reduction of the number of parameters to be optimised.

Texte intégral

Résumé :

The main recommendations of the Panel report can be summarised as follows: The Overall Picture: more needs to be understood about the process of acculturation of indigenous communities; about the Atlantic, Breton strand of Neolithisation; about the ‘how and why’ of the spread of Grooved Ware use and its associated practices and traditions; and about reactions to Continental Beaker novelties which appeared from the 25th century. The Detailed Picture: Our understanding of developments in different parts of Scotland is very uneven, with Shetland and the north-west mainland being in particular need of targeted research. Also, here and elsewhere in Scotland, the chronology of developments needs to be clarified, especially as regards developments in the Hebrides. Lifeways and Lifestyles: Research needs to be directed towards filling the substantial gaps in our understanding of: i) subsistence strategies; ii) landscape use (including issues of population size and distribution); iii) environmental change and its consequences – and in particular issues of sea level rise, peat formation and woodland regeneration; and iv) the nature and organisation of the places where people lived; and to track changes over time in all of these. Material Culture and Use of Resources: In addition to fine-tuning our characterisation of material culture and resource use (and its changes over the course of the Neolithic), we need to apply a wider range of analytical approaches in order to discover more about manufacture and use.Some basic questions still need to be addressed (e.g. the chronology of felsite use in Shetland; what kind of pottery was in use, c 3000–2500, in areas where Grooved Ware was not used, etc.) and are outlined in the relevant section of the document. Our knowledge of organic artefacts is very limited, so research in waterlogged contexts is desirable. Identity, Society, Belief Systems: Basic questions about the organisation of society need to be addressed: are we dealing with communities that started out as egalitarian, but (in some regions) became socially differentiated? Can we identify acculturated indigenous people? How much mobility, and what kind of mobility, was there at different times during the Neolithic? And our chronology of certain monument types and key sites (including the Ring of Brodgar, despite its recent excavation) requires to be clarified, especially since we now know that certain types of monument (including Clava cairns) were not built during the Neolithic. The way in which certain types of site (e.g. large palisaded enclosures) were used remains to be clarified. Research and methodological issues: There is still much ignorance of the results of past and current research, so more effective means of dissemination are required. Basic inventory information (e.g. the Scottish Human Remains Database) needs to be compiled, and Canmore and museum database information needs to be updated and expanded – and, where not already available online, placed online, preferably with a Scottish Neolithic e-hub that directs the enquirer to all the available sources of information. The Historic Scotland on-line radiocarbon date inventory needs to be resurrected and kept up to date. Under-used resources, including the rich aerial photography archive in the NMRS, need to have their potential fully exploited. Multi-disciplinary, collaborative research (and the application of GIS modelling to spatial data in order to process the results) is vital if we are to escape from the current ‘silo’ approach and address key research questions from a range of perspectives; and awareness of relevant research outside Scotland is essential if we are to avoid reinventing the wheel. Our perspective needs to encompass multi-scale approaches, so that ScARF Neolithic Panel Report iv developments within Scotland can be understood at a local, regional and wider level. Most importantly, the right questions need to be framed, and the right research strategies need to be developed, in order to extract the maximum amount of information about the Scottish Neolithic.
