Retournement temporel électromagnétique : cartographies d'énergie et localisation, du modèle numérique à l'expérimentation contrôlée / Electromagnetic time reversal : energy mapping and localization, from the numerical model to the controlled experimentation

Benhamouche, Mehdi 21 December 2012 (has links)
Le retournement temporel exploite la réversibilité temporelle de l’équation d’onde dans les milieux sans perte. Cela implique qu’une onde émise par une source peut rebrousser chemin et se focaliser sur sa source originale par le biais d’un miroir à retournement temporel. Cette focalisation permet de situer l’emplacement de cette source. Le but de cette thèse est d’exploiter le phénomène de retournement temporel d’ondes électromagnétiques en vue de la localisation et la caractérisation partielle d’objets diffractants enfouis dans un milieu sans perte. Notre étude est menée dans le domaine temporel large bande en se basant sur une modélisation numérique par la technique d’intégration finie.Le domaine temporel est un domaine assez peu exploré dans la littérature contrairement au domaine fréquentiel. La principale problématique est la détermination de l’instant de focalisation qui nous permet de choisir la distribution des champs à partir de laquelle les objets diffractants seront localisés. Nous introduisons dans ce manuscrit un critère de choix d’instant de focalisation qui est comparé tout au long des études entreprises au critère du minimum d’entropie.La démarche empruntée exploite l’analyse de cartographies d’énergie électromagnétique en deux et trois dimensions. Elle est validée dans un premier temps par l’analyse de configurations canoniques exploitant des données synthétiques obtenues par simulation. L’influence de divers paramètres relatifs aux objets diffractants est étudiée de même que l’impact du nombre d’émetteurs récepteurs du miroir à retournement temporel. Dans une seconde étape une expérimentation contrôlée en chambre anéchoïque à SUPELEC est réalisée en utilisant des antennes en régime harmonique et en régime impulsionnel. / Time reversal is, as is now well-known, exploiting the temporal reversibility of the wave equation in assumed lossless media. To summarize, it implies that a wave emitted by a given source may turn back and thereupon focus onto its original source by means of a so-called Time Reversal Mirror (TRM), which operation, properly simulated from field data acquired in a given measurement domain, could enable us to locate the source indeed. The aim of this thesis is to exploit the phenomenon of time reversal for the localization and the partial characterization, whenever possible, of diffracting objects (dielectric and conducting scatterers, in which sources are induced by given antennas, usually dipole-like) that are buried in a lossless medium (it can be a free space or a half-space) within a fully 3-D transient electromagnetic context. Time-domain certainly is a less explored area in the literature than frequency-domain, and this 3-D context (even if some 2-D validation studies are led also in the present work) is particularly demanding, computatinally speaking as well as at the level of real laboratory experiments. In addition, it requires that we be able to accurately compute the vector electromagnetic field in this time domain in an appropriate wideband situation, as well as whatever field is time reversed during the experiments, which are tasks performed via a full-wave Finite Integration Technique (FIT) developed at LGEP as is validated and discussed in some length in the manuscript. The main problem however is the determination of the moment of focus which would enable us determine the location of the scatterers at least to some extent. Here, to that effect, we introduce and discuss in depth a new criterion of choice of the instant of focus, which is in particular compared throughout the studies undertaken to the usually employed minimum entropy criterion. Influences of the various parameters of the scatterers themselves and of the measurement set-ups are thoroughly discussed on the way. Let us emphasize that what matters to us is the behavior of the (time-reversed) electromagnetic energy and not only of the electric field as standard, that is, the approach taken builds and uses the analysis of energy maps obtained by the aforementioned 3-D numerical modeling. Beyond the modeling of pure synthetic field data and discussions thereof, much attention is also given to leading controlled experiments on canonical targets using both transient and frequency-diverse time-harmonic sources within an anechoic chamber which was made available to us in SUPELEC.

L’intégration socio-scolaire et les stratégies identitaires d’adolescents iraniens à Montréal

Aghasi-Sorkhabi, Lida 09 1900 (has links)
Cette recherche a pour objectif de mieux explorer la problématique de l’intégration sociale et scolaire des jeunes immigrants, en nous penchant spécifiquement sur le vécu d'adolescents iraniens récemment arrivés au Québec. Nous tentons, entre autres, d’identifier les conflits de valeurs entre les parents et les adolescents d’une part, et de cerner les stratégies identitaires de ces adolescents face à ces conflits, d’autre part. Enfin, elle essaie de comprendre la perception des parents de ces adolescents envers ces enjeux. Dans cette étude, l’intégration sociale est principalement abordée sous l’angle des stratégies d’acculturation par le biais d’entrevues qualitatives auprès de quatorze jeunes de 13 à 18 ans ainsi que leurs parents (neuf). L’analyse des données démontre que ces jeunes ont un discours positif sur leur intégration scolaire et sociale. Le vécu familial et leurs choix de vie sont influencés essentiellement par leur milieu familial. L’influence de leurs amis – en général d’origine diversifiée – se limite à l’utilisation de leur temps libre. Ils croient aux valeurs traditionnelles iraniennes, tout en essayant d’être indépendants, libres et d’adopter un style de vie influencé par la société d’accueil qui peut conduire à des conflits potentiels avec leurs parents. Lorsque cela est le cas, les principales stratégies identitaires de ces jeunes sont celles de la cohérence complexe ou de la cohérence par modération des conflits de codes de vie. Par ailleurs, nous avons noté que le développement chez ces jeunes d’un sentiment d’appartenance à leur pays d’accueil repose principalement sur leur scolarisation. En résumé, nous pouvons constater que les jeunes d'origine iranienne, récemment arrivés au Québec, s’adaptent relativement facilement à leur nouvel environnement de vie tout en conservant leur attachement à leur culture d’origine. Ceci nous permet de conclure que leur processus d’intégration correspond peu à l’aliénation des jeunes musulmans maintes fois décrite dans la littérature internationale et nationale. Mots-clés : Intégration sociale et scolaire, conflits de valeurs, stratégies identitaires, adolescents, immigrants iraniens. / This exploratory research aims to study academic and social integration of teenagers of Iranian origin recently arrived in Québec. It attempts to identify conflicts of values between parents and these teenagers and to discover identity strategies of these teenagers vis-a-vis these conflicts. It also tries to identify the strategies used by these teenagers to attain social and academic integration in school. Moreover, we try to understand the perception of the parents of these teenagers towards these issues. In this study, social integration is mainly approached with respect to strategies of acculturation by conducting qualitative interviews with fourteen adolescents ages 13-18 and their parents (nine). The analysis of gathered data shows that these young people adapt easily to their new environment while preserving their attachment to their culture of origin. Their life choices are influenced essentially by their family environment. The influence of their friends, generally from diverse origins, mainly affects their leisure and use of free time activities. They believe in the Iranian traditional values while trying to be independent and free with a modern lifestyle, which can lead to potential conflicts with their parents. The preferred identity strategies of these teenagers are primarily those of complex coherence or coherence by moderation of the conflicts of codes. These young people have a positive opinion about their studies and do not seem to feel any conflict in their academic environment. In short, we can state that Iranian youth, recently arrived in Quebec, adapts relatively easily to their new living environment while conserving their attachment to their culture of origin. This enables us to conclude that their process of integration has little similarities with the alienation of Moslem youth often mentioned and described in the international and national literature. Keywords: Social and academic integrations, value conflict, identity strategies, adolescents, Iranian immigrants.

Genomic Variation and Evolution of HERV-H and other Endogenous Retroviruses (ERVs)

Jern, Patric January 2005 (has links)
An exogenous retrovirus (XRV) that integrates into a germ cell may be inherited as a Mendelian gene; it becomes an endogenous retrovirus (ERV). The human genome consists of up to 8% HERVs. The gammaretroviral (ERV class I) HERV-H, with 926 members, is the largest ERV group. Despite millions of years since integration, it has polymorphic envelope open reading frames in at least three loci. Selections for functional envelopes are indicated on chromosomes 1 and 2. However, envelopes were present only in a fraction of the total HERV-H. Mutated polymerases, indicating old ERVs, contradicted relatively intact long terminal repeats. To explain this, we formulated a “Midwife” element theory where proteins are complemented in trans. A phylogenetic analysis did not support separate HERV-H and -F groups. The new taxonomy included HERV-H like (RGH2-like and RTVLH2-like subgroups) and Adjacent HERV-H like. A bioinformatic reconstruction of a putative ancestral HERV-H exposed novel traits. Two nucleocapsid zinc fingers and a pronounced nucleotide bias for C in the HERV-H like were unique among the gammaretroviruses. Two recently integrated gammaretroviral groups (PtNeo-I[PTERV1] and -II) were found in chimpanzees but not in humans. The PtNeo groups were most similar to baboon ERVs and a macaque sequence, but neither to other chimpanzee nor to any human gammaretroviruses. The pattern was consistent with cross-species transfer via predation. To advance the retroviral taxonomy, we projected structural markers over sequence phylogenetic trees. A number of markers were useful to distinguish between genera and to delineate groups. Basic retroviral knowledge is vital to understand emerging infections. Phylogenetic analyses of taxonomically improved sequences, facilitates the search for common retroviral denominators to target. This thesis provided new insights in retroviral evolution and taxonomy using the ERVs, with special focus on the large gammaretroviral HERV-H group, as an additional source of information next to that of XRVs.

No. of bitstreams: 1 Antiquera_DanieldeCampos_M.pdf: 1223976 bytes, checksum: b8117290cd5c1f3a54124d4c42ef46dd (MD5) Previous issue date: 2006 / Resumo: Este trabalho analisa o Tratado de Cooperação Amazônica, assinado por Brasil, Bolívia, Colômbia, Equador, Guiana, Peru, Suriname e Venezuela em 1978, e suas transformações até se converter numa organização internacional (2002). O estudo busca relacionar essas mudanças no TCA com os diferentes momentos da política externa brasileira, visando em primeiro lugar a avaliar a importância da Amazônia para a política exterior do Brasil, e também a compreender o peso que a posição brasileira representa na evolução do Tratado. A partir do fim da década de 1980 há uma renovação no impulso dado ao TCA, que culmina com o protocolo de emenda, assinado em 1998, e a instalação de uma secretaria permanente, em Brasília, em 2002. Tal processo tem poucos estudos, embora indique uma renovação de expectativas sobre o Tratado. O trabalho foi feito por meio da análise de bibliografia sobre o TCA e a política externa, bem como sobre documentação oficial de ambas: discursos, atas de reuniões, declarações, estrutura jurídica. As informações foram complementadas com entrevistas realizadas com atores relevantes para o andamento do Tratado. A contribuição que este trabalho possa vir a dar é acrescentar outra perspectiva às leituras tradicionalmente liberais (no sentido de centrarem-se na cooperação e nos interesses comuns) que em geral são feitas sobre o objeto. Ao mesmo tempo, pretende-se chamar a atenção para a Amazônia e o norte da América do Sul como um espaço específico e importante das relações internacionais do Brasil / Abstract: This work analyzes The Amazon Cooperation Treaty, signed down by Brazil, Bolivia, Colombia, Equador, Guiana, Peru, Suriname e Venezuela in 1978, and its transformations until converting into international organization (2002). The study intends to establish a relation between those changes on ACT and different moments in brazilian foreign policy, looking for value amazonian role in this policy as well as for the brazilian role on the evolution of the Treaty. Since the end of the 80¿s, new strengths focused on ACT lead up to a renew¿s protocol, signed in 1998, and a permanent secretariat at Brasília, in 2002. There are few studies about these processes even than it indicates new expectations about the Treaty. The work was made analyzing the bibliography of ACT and of the foreign policy, as well as the official documentation of both of them. Also interviews have been made with important people involved in the Treaty. The eventual contribution of these research is offering a new perspective of the usually liberals (that focus on cooperation and common interests) points of view of the study¿s object. At the same time, there is the intention of getting attention for Amazon and for the north of South America as important areas of brazilian¿s international relations / Mestrado / Política Externa / Mestre em Relações Internacionais

Organizational culture's role in the integration phase of M&A transactions : A case study based on recent transactions / Organisationskulturens roll i integrationsfasen av M&A transaktioner : En fallstudie baserad på nyligen genomförda transaktioner

Bågevik Gray, Amelia, Johansson Lemon, Samuel January 2023 (has links)
The term mergers and acquisitions (M&A) is a collective name for a certain type of financial transaction, in which two organizations become a single entity (Rosenthal 2002, Seo & Hill 2005, Silhan 1994). In the post-M&A transaction process, the phase of integrating the organizations together emerges. These strategies can either be to absorb the acquiring organizations into the acquirer's entity or let the acquiring organizations stay fully preserved as stand-alone organizations. Another integration strategy includes transforming both organizations, where both parties adapt to each other (Marks & Mirvis 2010).  Despite the vast number of resources poured into the field, M&A transactions still have a high faliure rate (Homburg & Bucerius 2006, Marks 2001, Saunders et al. 2009). A failed M&A transaction does not only result in the loss of financial capital for the involved organizations but could also lead to people losing their jobs and potential environmental consequences. Because of this organizations become less efficient and therefore must spread their resources on activities that do not yield a positive result (Marks & Mirvis 2010, Schweiger & Goulet 2005). With Boateng & Lodorfos (2006) uncovering how “culture plays a key role in theintegration process and consequently the overall success of M\&As" and Hofstede (2001)claims that organizational culture are possible to manipulate. With these key statements,the purpose of this study is to investigate organizational culture and its role in theintegration process. The following research questions were created: 1.How do managers from different organizational cultures perceive the same integrationstrategy into a knowledge-centered organization? 2.How can an acquiring organization work with different organizational cultures during anintegration? In the thesis, we studied multiple organizations, the "umbrella organization" whichspecializes in conducting M&A transactions as a strategy for growth, and some of the organizations they have acquired and are undergoing integration into the umbrella organization. The thesis was conducted with a mixed method with a survey inspiredmostly by Schweiger & Goulet (2005) and Hofstede (2001) combined with semi-structured interviews to enable us to examine certain integration factors and cultural dimensions thatwe used in order to find correlations between them. In combination with this, we investigated how all the organizations perceived the integration to transpire based on theintegration framework by Marks & Mirvis (2010) and if organizational culture played a rolein how an organization should customize these strategies. Our findings suggest that having employees within certain cultures can affect the perception of how one sees the integration strategy, indicating that the umbrella organization and the acquired organizations are not aligned in their perception of the integration strategies. In order to enhance the effectiveness and potential success of integration we propose that it could be beneficial to customize the integration approach and strategy depending on each individual M&A transaction. Limitations of this study can be connected to the quantitative method since the results are restricted to a small sample size from one case organization as well as only investigating the correlation and not the causality between variables. / Termen mergers and acquisitions (M&A) är ett samlingsnamn för en viss typ av finansiell transaktion, där två organisationer går ihop och blir en enda enhet (Rosenthal 2002, Seo & Hill 2005, Silhan 1994). I processen efter M&A transaktioner uppstår fasen med att integrera organisationerna tillsammans. Dessa strategier kan antingen vara att absorbera de förvärvande organisationerna i förvärvarensenhet eller låta de förvärvande organisationerna förbli helt bevarade som fristående organisationer. En annan integrationsstrategi inkluderar att transformera båda organisationerna, där båda parter anpassar sig till varandra (Marks & Mirvis 2010). Trots den stora mängd resurser som läggs på att studera M&A transaktioner har de fortfarande en hög misslyckande grad (Homburg & Bucerius 2006, Marks 2001, Saunders et al.2009). En misslyckad M&A transaktion leder inte bara till förlust av finansiellt kapital för de inblandade organisationerna utan kan också leda till att människor förlorar sina jobb och potentiella konsekvenser för hållbarhet. På grund av detta blir organisationer mindre effektiva och måste därför sprida sina resurser på aktiviteter som inte ger ett positivt resultat (Marks & Mirvis 2010, Schweiger & Goulet 2005). Boateng & Lodorfos (2006) avslöjade hur "kultur spelar en nyckelroll i integrationsprocessen och följaktligen den övergripande framgången för M&As" och Hofstede (2001) hävdar att organisationskulturen är möjlig att manipulera. Med dessa nyckelpåståenden är syftet med denna studie att undersöka organisationskultur och dess roll i integrationsprocessen. Följande forskningsfrågor skapades: 1.Hur uppfattar chefer från olika organisationskulturer samma integrationsstrategi in i en kunskapscentrerad organisation? 2.Hur kan en förvärvande organisation arbeta med olika organisationskulturer under en integration? I avhandlingen studerade vi flera organisationer. Den förvärvande organisationen, "paraplyorganisationen", är specialiserad på att genomföra M&A transaktioner som en strategi för tillväxt. Examensarbetet har genomförts med en blandad metod genom en undersökning inspirerad till mestadels av Schweiger & Goulet (2005) och Hofstede (2001) kombinerat med semistrukturerade intervjuer. Detta för att vi ska kunna undersöka vissa integrationsfaktorer och kulturella dimensioner som vi använt för att hitta samband mellan dem. I kombination med detta undersökte vi hur alla organisationer uppfattade att integrationen skett baserat på integrationsramverket av Marks & Mirvis (2010) och om organisationskulturen spelade en roll i detta, samt hur paraplyorganisationen skulle kunna anpassa dessa strategier beroende på organisationernas olika kulturer. Våra resultat tyder på att olika kulturer uppfattar integrationen på olika sätt trots att den ska vara densamma. Detta indikerar att paraplyorganisationen och de förvärvade organisationerna inte är samordnade i sin uppfattning om integrationsstrategierna. För att förbättra integrationens effektivitet och potentiella framgång föreslår vi att det kan vara fördelaktigt att anpassa integrationsstrategin beroende på varje enskild M&A-transaktion. Begränsningar av denna studie kan kopplas till den kvantitativa metoden eftersom resultaten är begränsade till en liten urvalsstorlek från en fallorganisation samt endast undersöker korrelationen och inte kausaliteten mellan variabler.
