Uma enorme quantidade de ilustrações, peças, balés, músicas, filmes, programas de TV e outros foram feitos por artistas conceituados e menos conhecidos. Não existe, no entanto, uma abordagem sistemática desse fenômeo no campo específico da intermidialidade e da tradução intersemiótica. Dois exemplos notáveis servirão para análise: uma famosa série de TV de Jim Henson, The Muppet Show , que foi ao ar entre 1976 e 1981, estrelando fantoches e uma pessoa convidada em que um episódio da quinta temporada levou Brooke Shields interpretando Alice em 1980; e um filme de 1988 com uma mistura de stop motion e animação pelo muitas diretor tcheco vezes premiado, Jan Švankmajer, intitulado Neco z Alenky . Pretendemos aqui comparar essas duas traduções dos romances de Alice, em que os tradutores escolheram características do livro opostas entre si, porém ambas de importância fundamental para a fonte. / Alice’s Adventures In Wonderland and Through the Looking Glass And What Alice Found There , Lewis Carroll’s most famous books, have been widely intersemiotically translated throughout the last 150 years. A number of illustration, plays, ballets, songs, movies, TV shows and others was made by renowned and lesser known artists. There is not, however, a systematic approach of this phenomenon in a more strict field of analysis of intermediality and intersemiotic translations. Two notable examples will serve for analysis: a famous TV series by Jim Henson, The Muppet Show , aired from 1976 to 1981, featuring puppets and a human guest, in which an episode from the fifth season starred Brooke Shields playing Alice in 1980; and 1988 film with a blend of stop motion animation by multiple prize winner Czech director Jan Švankmajer, called Neco z Alenky . We intend to compare these translations of Alice’s novels, in which translators choose opposingly distinct characteristics of the books, but both of fundamental importance to the source.

In the novel Alice’s Adventures in Wonderland by Lewis Carroll, Alice, the protagonist, is supposed to be seven years of age. However, the reader can perceive her as older than that and get the impression that she has entered adolescence. Alice vacillates between being a child and striving to act like an adult in her various encounters in Wonderland. In this essay, I will examine Alice’s emotional and intellectual phases in her search for identity, and show the different levels according to developmental theory. Erik Erikson’s, Jean Piaget’s and John Dewey’s research together with other studies form the theoretical framework of this paper. I will demonstrate that while the book does not trace her development as such (i.e. it is not a typical Bildungsroman), it nevertheless highlights a child’s development by juxtaposing different developmental stages. The scientific and realistic functions of developmental theory may at first seem haphazard in the analysis of a literary character in a fantasy world. But, this essay illustrates Carroll’s professional familiarity with his child protagonist through the logic and consistency of his depiction of Alice.  Alice’s adventures in Wonderland reflect the child-adult conflict of Alice on her inner quest for identity. To her the first steps into adulthood, ie. adolescence, include not only psychological growth as in maturity but also physical growth; to grow is to grow up. Her dramatic alterations in size in Wonderland cause great turmoil and confusion as she senses an obligation to adapt her behavior.  Lewis Carroll knew his child protagonist well.

L’expérience ALICE au LHC étudie le plasma de quarks gluons (PQG), état de la matière où quarks et gluons existent à l’état déconfinés. Une des sondes utilisée pour explorer cet état est l’étude de plusieurs résonances (ρ, ω, ф, J/ψ et Ƴ) via leur canal de désintégration dimuonique, à l’aide d’un spectromètre à muons couvrant les pseudo-rapidités -4 < η < -2.5. La première partie de la thèse se focalise sur les mésons vecteurs de basses masses (ρ, ω et ф) . Elle concerne l’analyse des données récoltées en 2010 en collisions pp à √s = 7 TeV et Pb-Pb à √sNN = 2.76 TeV. Les mésons vecteurs de basses masses sont des outils intéressants pour sonder le PQG grâce à leurs faibles durées de vie et leur canal de désintégration dimuonique non affecté par les interactions dans l’état final. Les taux de production et fonctions spectrales de ces mésons sont modifiées par le milieu hadronique chaud et le PQG. En collisions pp, les distributions du ф, du (ρ+ω) en fonction de l’impulsion transverse ainsi que les sections efficaces et sections efficaces différentielles de production des différents mésons ont été extraites. L’analyse en collisions Pb-Pb ainsi que ses perspectives sont également présentées. La seconde partie de la thèse concerne le futur de l’expérience ALICE et les plans d’amélioration des détecteurs pour l’horizon 2017. Une étude de faisabilité pour l’ajout d’un trajectographe en pixels de Silicium (MFT) à l’avant de l’absorbeur hadronique dans l’acceptance du spectromètre à muons est présentée. Les performances et améliorations apportées par le MFT dans différents canaux de physique ont été étudiées en simulation / ALICE experiment at LHC studies the Quark Gluon Plasma (QGP), a particular state of matter where quarks and gluons are deconfined. A probe to explore this state is the study of several resonances (ρ, ω, ф, J/ψ and Ƴ) through their dimuon decay channel, with a muon spectrometer covering pseudo-rapidity -4 < η < -2.5. In the first part of this thesis, the focus is on light vector mesons (ρ, ω and ф) and their analysis in the 2010 data, in pp collisions at √s = 7 TeV and Pb-Pb collisions at √sNN = 2.76 TeV. Light vector mesons are powerful tools to probe the QGP due to their short lifetime and their dimuon decay channel. Indeed, leptons have negligible final state interactions. Production rates and spectral functions of those mesons are modified by the hot hadronic and QGP medium. In pp collisions, pT distributions, production cross sections and pT-differential cross sections of the different mesons have been extracted. The Pb-Pb analysis and its prospects are also presented. The second part of the thesis concerns ALICE upgrades plans of year 2017. A feasibility study for a Muon Forward Tracker (MFT) in Silicon pixels located upstream of the hadronic absorber, in the spectrometer acceptance, was performed. Performances and improvements brought by the MFT on several physics cases were in simulations

Dans les collisions d'ions lourds ultra-relativistes (A-A), la matière se trouve dans des conditions extrêmes de densité d'énergie; elle forme un plasma de quarks et de gluons déconfinés. Aux énergies du RHIC et du LHC, le rapport baryon sur méson, tel Λ/K0S, prend des valeurs élevées sur une plage d'impulsions transverses intermédiaires pour les collisions centrales A-A. L'objectif de ce travail est de vérifier si la production accrue de baryons est seulement due à des effets collectifs au cœur du système formé ou s'il existe aussi un impact lié à une fragmentation des partons modifiée par le milieu. À l'aide de corrélations angulaires à deux hadrons, les K0S et Λ produits en association avec un hadron de haut pT (processus durs) sont séparés de ceux issus du milieu thermalisé (processus softs). Les rapports Λ/K0S à relier aux mécanismes durs et softs sont établis; les résultats sont obtenus pour les collisions Pb-Pb à √sNN = 2.76 TeV enregistrées en 2011 avec l'expérience ALICE. / In ultrarelativistic heavy-ion collisions, the QCD matter is under extreme conditions of energy density, forming a quark-gluon plasma (QGP), in which quarks and gluons are deconfined. At RHIC and LHC energies, a large baryon-to-meson ratio, like Λ/K0S, was observed within the transverse momentum range 2 < pT < 6 GeV/c for central heavy-ion collisions. The goal of this dissertation is to verify if the baryon-to-meson enhancement is only due to collective effects of the bulk of matter, and if there is also a contribution related to in-medium modifications of parton fragmentation.With two-hadron angular correlations, the K0S and Λ produced in association to an energetic hadron (hard processes) are separated from those originated from the thermalised medium (soft processes). The differential Λ/K0S ratios related to the soft or hard production processes are extracted. The results are obtained for the Pb-Pb collisions at √sNN = 2.76 TeV recorded in 2011 with the ALICE experiment.

Ce travail contribue au programme de recherche et de développement d'un capteur CMOS à pixel qui pourrait satisfaire pleinement les spécifications du nouvel ITS (Inner Tracking System : trajectomètre interne) de l'expérience ALICE. Afin de briser les limites de la CPS de pointe, une technologie CMOS 0.18 µm à quatre puits a été explorée. Les capteurs fabriqués dans cette nouvelle technologie ont montré une meilleure tolérance aux radiations que les capteurs réalisés dans une technologie CMOS 0.35 µm plus ancienne. En outre, cette nouvelle technologie offre la possibilité d’implémenter des transistors de type P dans chaque pixel sans dégrader la capacité de collection de la diode. Il devient donc possible d’intégrer un discriminateur dans chaque pixel et obtenir un pixel à sortie binaire. En conséquence, la consommation sera largement réduite. De plus, le temps de traitement de la ligne peut être potentiellement réduit. Un premier prototype de petite taille, intitulé AROM-0, a été conçu et fabriqué afin d’étudier la faisabilité de la discrimination de signal dans un petit pixel. Dans ce prototype, chaque pixel de surface 22 × 33 µm2 contient une diode de détection, un préamplificateur et un discriminateur à tension d’offset compensée. La performance de bruit des différentes versions de pixels dans le capteur AROM-0 a été évaluée. Ensuite sera détaillé le développement des capteurs AROM-1. Ce sont les capteurs intermédiaires vers le capteur final proposé par notre groupe. Ils ont deux objectifs principaux, l’un est de valider les optimisations de conception du pixel et l’autre est de mettre en place une architecture du capteur évolutive intégrant l’intelligence nécessaire dans le circuit. Cette thèse présente en détail la conception et les résultats de mesure de ces capteurs AROM. / This work is part of the R&D program aimed for a CMOS pixel sensor (CPS) complying with the requirements of the upgrade of the inner tracking system (ITS) of the ALICE experiment. In order break the limitations of the state-of-the-art CPS, a 0.18 µm quadruple-well CMOS process was explored. Besides an enhanced radiation tolerance, with respect to the former sensors fabricated in a 0.35 µm process, the sensor based on this new process allows for full CMOS capability inside the pixel without degradation of the detection efficiency. Therefore, the signal discrimination, which was formerly performed at the column level, can be integrated inside the pixel. As a result, the readout speed and power consumption can be greatly improved as compared to the CPS with column-level discrimination. This work addresses the feasibility study of achieving the signal discrimination withina small pixel (i.e. 22 × 33 µm2), via the prototype named AROM-0. The pixel of AROM-0 contains a sensing diode, a pre-amplifier and an offset compensated discriminator. The noise performance of the various pixel versions implemented in AROM-0 was evaluated. The study was further pursued with the AROM-1 prototypes, incorporating the optimized pixel designs and the necessary on-chip intelligence to approach the final sensor we have proposed for the ALICE-ITS upgrade. This thesis presents in detail the design and the measurement results of these AROM sensors.

Les collisions d’ions lourds au LHC permettent l’étude des propriétés de la matière nucléaire soumise à des conditions extrêmes de température et densité d’énergie où on assisterait à la formation du Plasma de Quarks et Gluons (QGP). La mesure des saveurs lourdes ouvertes (charme et beauté) est particulièrement intéressante pour l’étude des propriétés du QGP. L’étude des collisions d’ions lourds au LHC nécessite aussi la mesure des collisions pp et p–Pb. Les collisions p-Pb permettent en particulier d’étudier les effets nucléaire froids et d’interpréter les effets nucléaires chauds observés dans les collisions Pb–Pb. Cette thèse est dédiée à l’étude de la production des saveurs lourdes ouvertes via les muons simples dans les collisions p–Pb à √8NN = 5.02 TeV aux rapidités avant et arrière avec le détecteur ALICE au LHC. La référence pp est estimée à partir des mesures pp à √8 = 2.76 TeV et 7 TeV et utilisant des calculs pQCD pour l’extrapolation à √8 = 5.02 TeV. Les mesures du facteur de modification nucléaire (RpPb) et du rapport des sections efficaces aux rapidités avant et arrière indiquent que les effets nucléaires froids sont faibles sur tout le domaine en impulsion transverse (pT) aux rapidités avant (RpPb ≈ 1). Aux rapidités arrière, le facteur de modification nucléaire est sensiblement plus grand que un dans la région 2 < pT < 4 GeV/c. Les résultats confirment que la forte suppression des taux de production des muons issus du charme et de la beauté mesurée dans les collisions centrales Pb–Pb est due au milieu dense et chaud. Le facteur de modification nucléaire et le rapport des sections efficaces aux rapidités avant et arrière sont aussi mesurés en fonction de la centralité dans les collisions p-Pb. Le facteur de modification nucléaire reste compatible avec l’unité à grand pT dans les collisions centrales. / The LHC heavy-ion physics program aims at investigating the properties of strongly-interacting matter in extreme conditions of temperature and energy density where the Quark-Gluon Plasma (QGP) is formed. In high-energy heavy-ion collisions, heavy quarks (charm and beauty) are regarded as efficient probes of the properties of the QGP. The heavy-ion physics program requires also the study of proton-proton (pp) and proton-nucleus (p–Pb) collisions. The study of p–Pb collisions is used to investigate cold nuclear matter effects and to validate and quantify hot nuclear matter effects which are observed in nucleus-nucleus (Pb–Pb) collisions. This thesis work is devoted to the study of open heavy-flavour production at forward and backward rapidity via single muons in p–Pb collisions at √8NN = 5.02 TeV with the ALICE experiment at the LHC. The pp reference using available measurements at 2.76 and 7 TeV and a pQCD-driven method for the scaling to 5.02 TeV is estimated. The measurements of the nuclear modification factor (RpPb) at forward and backward rapidity and forward-to-backward ratio in p–Pb collisions, indicate that cold nuclear matter effects are small over the whole transverse momentum (pT) region at forward rapidity (RpPb compatible with unity within uncertainties). In the backward rapidity, the nuclear modification factor deviates from unity in the intermediate pT region (2 < pT < 4 GeV/c). These results confirm that the strong suppression measured at high pT in central Pb–Pb collisions is due to final-state effects induced by the hot and dense nuclear medium. The results of the nuclear modification factor and forward-to-backward ratio as a function of centrality in p–Pb collisions are discussed. Even in central collisions, the nuclear modification factor is compatible with unity at high pT.

[pt] Com foco em processo criativo e transmidialidade, esta pesquisa propõe investigar a dinâmica criativa irreversível impulsionada por Lewis Carroll, através de suas duas obras aclamadas, as Alices. Da era vitoriana à arte contemporânea, Wonderland e Looking-Glass se mantêm em devir, reinventadas nas mãos de artistas que, inspirados pelo universo do autor, mesclam realidade e ficção ao integrar a biografia à obra. O fenômeno cultural se torna transmidiático, não de maneira estratégica e centralizada, mas de forma orgânica e caótica, através de inúmeros produtores visuais dispersos no tempo e no espaço. Muitos desses produtores têm formação em design e, ao atuarem em áreas correlacionadas e mídias diversas – como ilustração, fotografia, arte, cinema e games –, parecem desenvolver uma atitude projetual criativa que os permite colaborar com o fenômeno cultural em expansão. Propõe-se, assim, identificar não só as convergências e divergências entre linguagens visuais e mídias, como o pensamento do produtor visual em seu fazer projetual, artístico e poético. Ao mapear exemplos da visualidade de Alice, a intenção é a de delinear as características dessa dinâmica, que, através da repetição e dos desvios, permite à narrativa uma constante ressignificação. Acredita-se que, como obras abertas à iniciativa do leitor e do artista, as histórias nonsense contribuam como elementos catalizadores de novos processos criativos: na dinâmica de Alice, criam-se novas relações de autoria e coautoria, de produção, recepção e mediação. Ao fazer reverberar, sobretudo, diferentes vozes interdisciplinares, esta pesquisa pretende apresentar uma abordagem teórica, crítica e filosófica sobre questões da pós-modernidade presentes em Alice. / [en] Focusing on the creative process and transmedia, this research proposes investigating the irreversible creative dynamic driven by Lewis Carroll through his two acclaimed works: the Alices. From the Victorian era to contemporary art, Wonderland and Looking-Glass continue to be reinvented through the hands of artists who, inspired by the author s universe, mix reality and fiction by integrating biography into the artwork. The cultural phenomenon becomes transmedia, not in a strategic and centralized way, but organically and chaotically, through countless visual producers dispersed in time and space. Many of these producers are designers working in related areas and different media – such as illustration, photography, art, cinema and games –, who seem to develop a creative design attitude that allows them to collaborate with the expansion of the cultural phenomenon. The proposal includes identifying convergences and divergences not only between visual languages and media but also between the ideas and thoughts of the visual producers, during their artistic and poetic work in process. By mapping examples of the multiple visuality of Alice, the intention is to outline this dynamic s characteristics, which, through repetition and deviations, allows the narrative to be continuously reframed. It is believed that, as works that are open to the initiative of the reader and the artist, the nonsense story contributes as a catalyst element for new creative processes: in the Alice dynamic, there are new relationships of authorship and co-authorship, of production, reception and mediation. By echoing mainly different interdisciplinary voices, this research aims to present a theoretical, critical and philosophical approach to postmodernity issues present in Alice.

Les collisions d'ions lourds ultra-relativistes représentent le seul moyen pour appréhender en laboratoire le diagramme de phase de la QCD, la théorie de l'interaction forte. Les prédictions théoriques les plus récentes, obtenues par la technique de calcul sur réseau, prévoient une transition de phase entre la matière nucléaire froide (un gaz hadronique) et un plasma de quarks et de gluons (milieu déconfiné). Parmi les différentes sondes expérimentales possibles, l'intérêt des saveurs lourdes est en principe de pouvoir caractériser le milieu produit lors d'une collision entre ions lourds, mais également de pouvoir obtenir des informations sur son évolution spatio-temporelle. Leur étude peut se faire entre autres par le biais de leur canal de désintégration en muons. Cette Habilitation à Diriger des s développe dans une première partie la problématique des collisions d'ions lourds ultra-relativistes, en mettant l'accent sur l'étude des saveurs lourdes. Dans une deuxième partie, les résultats obtenus auprès du collisionneur RHIC (BNL, New York) sont passés en revus, et l'analyse du spectre en masse des dimuons menée au sein de l'expérience PHENIX est détaillée. Enfin, la troisième partie décrit d'une part les développements instrumentaux réalisés pour le système de déclenchement des muons dans l'expérience ALICE auprès du LHC (CERN, Genève), et d'autre part les performances attendues pour l'étude des dimuons.
