▼ It is a generation of high technology. Our daily life is full of computing in the aspects of work and leisure. Computing also influences on art, and now a computer can be a new form of representation. Artists use computers to create and show their art works, and viewers now not only view those art works but also involve in art works through the interactivity of a computer. Motion graphics are attractive. Flash based programs are rich in interaction. This project combines the two features to create a user driven art that promotes classical music to children and of course to every one. In such an interactive and attractive way, users enjoy the music and listen to the three world-known songs from Saint Saëns's Carnival of Animals- Royal March of Lion, Aquarium, and the Swan. When the music starts, by clicking the mouse, users can add motion graphics related to the music on a computer screen. It is a problem to figure out a way to generate pixel-based motion graphics with Flash, which usually deals with vector images. First built are the codes, that give this project functions of interaction. Users can choose a song, add motion graphics on a computer screen, pause or play the music, change the volume of the sound, choose different color, and print out images they create. The rest are the motion graphics, that reflect the unique theme of each song. In order to display well, different methods are examined to generate motion graphics, including loading FLV files exported by After Effects, and adding movie clips built in Flash, and more. The result shows that adding movie clips built in Flash is the best way. Other ways result in the pixilated edges of graphics, the difficulty of making alpha movies, or other technical problems. Having the capabilities of enabling users to control the program and displaying motion graphics in high quality, this project performs as a new medium introducing classical music to new generations.

▼ Diseases such as Alzheimer’s, Parkinson’s, eye lens cataracts, and Type 2 diabetes are the results of protein aggregation. Protein aggregation is also a problem in pharmaceutical industry for designing protein based drugs for long term stability. Disordered states such as precipitates and gels and ordered states such as crystals, micro tubules and capsids are both possible outcomes of protein–protein interaction. To understand the outcomes of protein–protein interaction and to find the ways to control forces, it is required to study both kinetic and equilibrium factors in protein–protein interactions. Salting in/salting out and Hofmeister effects are familiar terminologies used in protein science field from more than a century to represent the effects of salt on protein solubility, but they are yet to be understood theoretically. Here, we build a theory accounting both attractive and repulsive electrostatic interactions via the Poisson Boltzmann equation, ion–protein binding via grand cannonical partition function and implicit ion–water interaction using hydrated ion size, for describing salting in/salting out phenomena and Hofmeister and/or salt specific effect. Our model free energy includes Coulomb energy, salt entropy and ion–protein binding free energy. We find that the salting in behavior seen at low salt concentration near the isoelectric point of the protein is the output of Coulomb energy such that the addition of salt not only screens dipole attraction but also it enhances the monopole repulsion due to anion binding. The salting out behavior appearing after salting in at high salt concentration is due to a salt mediated depletion interaction. We also find that the salting out seen far from the isoelectric point of the protein is dominated by the salt entropy term. At low salt, the dominant effect comes from the entropic cost of confining ions within the aggregates and at high salt, the dominant effect comes from the entropy gain by ions in solution by enhancing the depletion attraction. The ion size has significant effects on the entropic term which leads to the salt specificity in the protein solubility. Crystal growth of anisotropic and fragile molecules such as proteins is a challenging task because kinetics search for a molecule having the correct binding state from a large ensemble of molecules. In the search process, crystal growth might suffer from a kinetic trap called self–poisoning. Here, we use Monte Carlo simulation to show why protein crystallization is vulnerable to the poisoning and how one can avoid such trap or recover crystal growth from such trap during crystallization. We show that self–poisoning requires only three minimal ingredients and these are related to the binding affinity of a protein molecule and its probability of occurrence. If a molecule attaches to the crystal in the crystallographic state then its binding energy will be high but in protein system this happens with very low probability (≈ 10−5). On the other hand, non–crystallographic binding is energetically weak, but it… Advisors/Committee Members: Jeremy D. Schmit.

▼ The small-scale processes (e.g., convective cells and gravity waves) that are often not fully resolved and represented by our forecast models, will affect processes at well-resolved scales and increase the uncertainties in our predictions. This thesis examines the scale interactions in predictability experiments using convection-permitting high-resolution ensembles of both global and regional scales, in order to study the intrinsic and practical predictability limit of in our numerical weather forecast.The first part of this dissertation is aimed at testing Zhang, Snyder and Rotunnos three-stage error growth hypothesis focusing on the role of moist convection in the upscale error growth behavior. In the dry experiment free of moist convection, error growth is controlled primarily by baroclinic instability, hence forecast accuracy is inversely proportional to the amplitude of the baroclinically unstable initial condition error. Therefore, the accuracy of the prediction can be continuously improved without limit through reducing the initial error. On the contrary, in a moist environment with strong convective instability, rapid upscale growth arises from moist convection. As a result, the forecast error becomes increasingly less sensitive to the scale and amplitude of the initial perturbations. These diminishing returns from more accurate initial conditions may ultimately impose a finite-time barrier to the forecast accuracy. Moreover, the inclusion of strong moist convection changes the mesoscale (wavelength smaller than 500 km) kinetic energy spectrum slope from 3 to approximately 5/3 in our simulations, which is consistent with observations. Since the error spectrum will adjust toward the slope of the background flow, this change in slope of the background flow in our simulations due to moist convection further highlights the importance of moist convection to both the intrinsic and practical limits of atmospheric predictability, especially at meso- and convective scales.Building upon the finding of the kinetic energy slope, in part two of this dissertation, it is further demonstrated that convective systems, triggered in a horizontally homogeneous environment, are able to generate a background mesoscale kinetic energy spectrum with a slope close to -5/3. To investigate the processes that are responsible for generating the -5/3 slope, spectral kinetic energy budget analysis is performed. The analyses show that the buoyancy production generated by moist convection, while mainly injecting energy in the upper troposphere at small scales, could also contribute to larger scales. The injected energy is then transported by energy fluxes (due to gravity waves and/or convection) both upward and downward. Nonlinear interactions, associated with the velocity advection term, finally helps build the approximate -5/3 slope through upscale/downscale propagation of the energy at all levels.The last part of the dissertation focuses on the influence of the upscale error growth to the operational forecast and the predictability gap… Advisors/Committee Members: Fuqing Zhang, Dissertation Advisor.

▼ Klotsapiini on tehokkain psykoosilääke muille psykoosilääkkeille hoitoresistentissä skitsofreniassa. Klotsapiinilla on aggressiivisutta sekä itsetuhoisuutta vähentävä vaikutus. Sen käyttöä rajoittavat kuitenkin lukuisat sivuvaikutukset, joista tunnetuin on agranulosytoosi. Myös klotsapiinin aiheuttamien myokardiiti, aspiraatiopneumonia, ileus sekä painon nousu voivat olla hengenvaarallisia ja ne voivat aiheuttaa enemmän kuolemantapauksia, kuin agranulosytoosi. Klotsapiinin käyttöön liittyvä granulosytopenia ja agranulosytoosi sekä sydäntulehdus voivat edellyttää klotsapiinihoidon välitöntä keskeyttämistä, jolloin psykoosin uusiutumis- ja pahenemisriski ovat suuria. Klotsapiinin käyttöön liittyy myös monia muita epämiellyttäviä hoitoa haittaavia sivuvaikutuksia, joita ovat esimerkiksi sedaatio, syljenerityksen lisääntyminen ja kouristuskynnyksen aleneminen. Klotsapiinilla on paljon yhteisvaikutuksia esimerkiksi muiden lääkkeiden kanssa. Se metaboloituu pääosin maksan sytokromijärjestelmän ja erityisesti CYP1A2:n kautta, joiden kautta monet lääkeaineet ja esimerkiksi tupakointi voivat vaikuttaa klotsapiinin metaboliaan. Ensimmäisessä osatyössä tutkittiin retrospektiivisesti äkillisen klotsapiinihoidon lopettamisen vaikutusta psykoosioireisiin kun lääkitys jouduttiin lopettamaan ilman potilaasta johtuvaa syytä. Aineiston muodostivat 28 Pitkäniemen sairaalassa hoidettua skitsofreniapotilasta, joiden klotsapiinilääkitys lopetettiin heinäkuussa 1975, kun klotsapiinin käyttö kiellettiin Lääkintöhallituksen määräyksellä kahdeksen klotsapiinihoitoa saaneen potilaan menehdyttyä agranulosytoosiin. Lopettamisen seurauksena psykiatriset oireet lisääntyivät nopeasti noin puolella potilaista. Oireiden lisääntymisen todennäköisyyttä vähensi antikolinergisen lääkityksen tai muun psykoosilääkkeen käyttö. Toisessa osatyössä tutkittiin tupakoinnin vaikutusta seerumin klotsapiinipitoisuuteen 44 sairaalahoidossa olevalla potilaalla. Tupakoivien potilaiden seerumin klotsapiinipitoisuudet olivat merkitsevästi matalampia (38 %) kuin tupakoimattomien potilaiden. Tupakoivilla potilailla oli tilastollisesti merkitsevästi suuremmat painoon suhteutetut klotsapiiniannokset, vaikka heidän seerumin klotsapiinipitoisuutensa oli pienempi. Kolmannessa ja neljännessä osatyössä käytettiin samaa kolmen sairaanhoitopiirin alueelta kerättyä 237:n klotsapiinipotilaan aineistoa. Kolmannessa osatyössä tutkittiin klotsapiinin subjektiivisia sivuvaikutuksia LUNSERS-itsearviointilomaketta käyttäen. Monimuuttuja-analyysissä todettiin yhteys seerumin klotsapiinipitoisuuden ja ilmoitettujen masennus-ahdistussivuvaikutuksen, nuoremman iän ja lääkityksestä koetun sedaation sekä lisääntyneen unien näkemisen välillä. Lisäksi psykoosilääkkeiden yhdistelmiä käyttävät potilaat raportoivat enemmän sympatikotonia-tensio -tyyppisiä oireita. Neljännessä osatyössä tutkittiin tupakoinnin ja painoindeksin välistä suhdetta klotsapiinihoitoa saavilla potilailla. Tupakoivien ja tupakoimattomien potilaiden painoindekseissä ei todettu eroa toisin kuin aiemmissa, normaaliväestöä…

Ce travail de thèse est dédié à l'étude des effets induits sur des matériaux à effet magnétocalorique géant par impact d'ions lourds. Ces matériaux présentent une transition de phase de premier ordre liée à une forte variation d'entropie potentiellement exploitable pour le développement de systèmes de réfrigération magnétique efficaces. En contrepartie la présence d'une hystérésis thermique et la faible gamme de température utile limitent leur potentiel. Dans ce travail, nous avons exploité les effets spécifiques de l¿impact des ions lourds à basse vitesse pour modifier ces caractéristiques, en engendrant du désordre et en créant des défauts ponctuels. Dans les couches minces d'arséniure de manganèse, qui possèdent une transition de phase magnéto-structurale, nous avons montré que ces défauts agissent comme des centres de nucléation et suppriment l'hystérésis thermique de façon stable dans le temps. En faisant varier les conditions d'irradiation, nous avons pu dégager le rôle fondamental de la densité de collisions élastiques induites par ces irradiations. Les effets des ions sur des couches minces de FeRh, un autre matériau à effet magnétocalorique géant présentant une transition de phase de type métamagnétique, ne permettent pas de supprimer l'hystérésis ce qui souligne l'importance de la présence d¿un changement de phase structurale dans le processus de suppression de l'hystérésis. Par ailleurs, nos investigations révèlent que le contrôle du nombre d'ions par unité de surface impactant l'échantillon permet de moduler la température de transition de phase. Cet effet constitue une nouvelle méthode prometteuse pour les applications.

This work aims to study the effects of slow heavy ions on giant magnetocaloric materials. These materials present a first order phase transition coupled to a strong variation of entropy potentially exploitable for the development of systems of effective magnetic refrigeration. On the other hand, the thermal hysteresis and the small range of working temperatures restrict the use of these materials. In this work, we exploited the specific effects of slow heavy ions impact to modify these characteristics. Ion collisions induce disorder and point-like defects into materials. In manganese arsenide thin films, presenting a magneto-structural transition, we demonstrated that this new defects act like nucleation centers which suppress the thermal hysteresis in a stable way in time. By varying irradiation conditions, we were able to highlight the fundamental role of the density of elastic collisions generated by these irradiations. Effects of ions in iron-rhodium thin films, another giant magnetocaloric material with a metamagnetic phase transition were also studied. In this case, the thermal hysteresis is not suppressed by the ions impact indicating that the phase structural change plays an important role in the reduction of the thermal hysteresis. Furthermore our investigations demonstrated that by controlling irradiation conditions, in particular the number of incident ions on a given sample…

Les canopées sont des assemblées compactes de plantes dont l'étude concerne de nombreuses problématiques environnementales. Des applications technologiques sont également envisageables. Les précédents travaux se sont principalement focalisés sur les écoulements au-dessus des canopées, considérées comme des rugosités de fond. La présence d'un point d'inflexion dans le profil de vitesses dans le fluide autorise le développement d'instabilités de type couche de mélange à l'interface. De plus, la prise en compte de la flexibilité des plantes complique le problème, car leur forme est modifiée par le courant pour réduire la traînée exercée sur elles – c'est le phénomène de reconfiguration – mais elles ont également une dynamique propre qui peut éventuellement influencer l'écoulement. La démarche envisagée dans cette thèse est essentiellement expérimentale. Elle cherche à comprendre la réaction des tiges à différents types d'écoulements, afin d'étudier les effets collectifs inhérents à la canopée, et d'identifier les mécanismes communs qui en sont à l'origine. On utilise pour cela des tiges modèles très simples dans un canal étroit, ce qui assure une configuration quasi 2D et facilite les observations. Dans un premier temps, on étudie la réaction statique de la canopée à un écoulement établi. L'effet de la densité est très clair tant que les plantes sont assez proches, sinon elles se comportent comme si elles étaient seules. Ensuite, la canopée est soumise à un écoulement oscillant (houle), et, de la même façon, on étudie la différence de réaction entre une tige seule et une tige incluse dans une canopée. La troisième partie s'intéresse à la dynamique de la canopée soumise à un écoulement unidirectionnel, permettant le développement d'instabilités au sommet de la canopée. Le régime de grandes ondulations cohérentes de la canopée, apparenté au ‘monami' de la littérature, est caractérisé

Vegetation in rivers is often considered as a source of water resistance which slows down the water conveyance. It is also one of the main component for river equilibrium, insofar as it prevents body erosion by providing bed stabilization, it plays a vital role during floods. It is crucial for sediment transport, water quality and also shelter to provide the necessary habitat for the biodiversity of aquatic species. It is then useful to understand the mechanical behaviour of aquatic canopies resulting from the interaction between vegetation and a water flow. From land-use planning to river management, such a knowledge would also shed light upon plant biomechanics and improve bio-inspired engineering.Traditionally, studies on aquatic vegetation explored its influence on flow properties, like velocity distribution, wake dynamics, turbulence, water conveyance and sediment transport by considering it simply as a rigid or flexible roughness element.This thesis is an experimental work which aims at understanding how a model canopy reacts to a water flow depending on the canopy geometry and the flow conditions. Three different series of…

L'état supraconducteur étant un condensat de paires de Cooper constitué d'électrons de moments et de spins opposés, il peut être fortement influencé par des effets de spin. Au cours de cette thèse, nous étudions l'effet d'un fort champ d'échange et d'un effet spin-orbite de type Rashba sur les propriétés supraconductrices. Dans une première partie, on étudie les effets associés à l'interaction entre supraconductivité et fort champ d'échange, se caractérisant par une transition de phase vers un état supraconducteur inhomogène découvert par Fulde, Ferrell, Larkin et Ovchinnikov (FFLO). On étudie tout particulièrement les fluctuations supraconductrices à l'approche de la transition de phase. On montre que ces fluctuations peuvent servir de révélateur à cette phase. Notamment, la capacité calorifique et la paraconductivité divergent de façon caractéristique à la transition vers un état modulé. On décrit également comment les effets paramagnétiques modifient les fluctuations de l'aimantation, annulant la réponse diamagnétique ou produisant des oscillations entre réponse para- et dia-magnétique. La seconde partie est dévolue aux jonctions supraconducteur-ferromagnétique (S/F). Dans les jonctions Josephson S/F/S, le champ d'échange donne lieu à des oscillations du courant critique en fonction de la longueur de la jonction, charactérisées par une alternance des états 0 et . On prédit une transition entre les états 0 et induite par la température, même dans la limite ballistique. Dans cette limite ballistique, on montre également que le courant de Josephson s'atténu sous la forme de lois de puissance en fonction de la longueur de la jonction, alors que le cas diffusif présente une atténuation exponentielle. On étudie ensuite la seconde harmonique de la relation courant-phase en présence d'une faible quantité d'impuretés. La dernière partie traite des effets de proximité lorsque les deux effets paramagnétique et spin-orbite sont présents dans une jonction Josephson. On montre que l'association d'une interaction Rashba et d'un champ d'échange induit un couplage direct entre les ordres magnétique et supraconducteur. En particulier, ce couplage permet de générer toute la dynamique magnétique par l'application d'une simple tension électrique.

The superconducting state being a Cooper pair condensate built on opposite spin and momentum electrons, it can be strongly influenced by any spin effect. In this thesis, we investigate the roles of strong paramagnetic and spin-orbit effects on superconducting properties. In a first part, the interplay between paramagnetic effect and bulk superconductivity is studied, leading to the modulated Fulde, Ferrell, Larkin and Ovchinnikov phase (FFLO phase). We focus on superconducting fluctuations near to the FFLO state. We show that these fluctuations can serve as a smoking gun for this phase. Noticeably, the fluctuation heat capacity and paraconductivity diverge in a characteristic way when approaching the phase transition towards a modulated state. Moreover, the fluctuation induced…

▼ The interactions between magnetic moments and electrons are essential in creating many of the unique properties of magnetic systems. In this thesis, I focused on two Fe-based systems employing multiple experimental techniques to investigate the coupling between localized magnetic moments and conducting charge carriers in two systems with tendencies to order into itinerant magnetic phases.\ With systematic investigations of Fe_1-yCo_ySi, we discovered a field depended non-Fermi-Liquid (non-FL) behavior near its insulator-metal-transition (IMT) that appears to share the same mechanism as previously discovered in Mn doped FeSi - the underscreened Kondo effect.\ A similar interaction of the charge carrier moments screening S=1 impurity moments are found in the y\approx0.01 range of Co doped FeSi as in Fe_1-xMn_xSi. %From magnetic property study, we observed a systematic increase of the Weiss temperature from Mn doping to Co doping. And Θ_w remains negative in the very low doping range of Fe_1-yCo_ySi. We have also found that the impurity moment in the low doping range of the Fe_1-yCo_ySi is S=1, similar as in Mn doped Si. The conductivity results indicate a field dependent non-FL behavior at IMT of Fe_1-yCo_ySi that transitions to a disordered FL dependence with the application of magnetic field or by increasing the density of Co substitutions. However, a small region of Co-substitution between 0.01<x ≤ 0.03 displays unique behavior which is enhanced by the application of magnetic field. We are presently exploring the consequences of this discovery. A relatively large density of unscreened or uncoupled magnetic moments at low temperature was confirmed through specific heat measurements at several magnetic fields over a wide range of temperatures. %Existence of the underscreen magnetic moments was confirmed by the large size of entropy missed at zero field that retrieved in fields.% from down to 300 mK survey. These findings support that the non-FL of Mn and Co doped FeSi corresponds to the underscreened Kondo mechanism and depends only on the local interaction rather than the charge carrier type. \ A second Fe-based magnetic system Fe₃Ga₄ was investigated via neutron scattering technique. In the neutron scattering investigations of on the Fe₃Ga₄ system, ferromagnetic (FM) ordered states are confirmed below 68 K and between 360 - 420 K. The antiferromagnetic state which exists at intermediate temperatures between two ferromagnetically ordered regimes consists of an incommensurate spin density wave (ISDW) order likely caused by RKKY interactions. The effect of magnetic fields and pressure on the magnetic states of this complex material were explored.

Este trabalho trata de uma avaliação do eventual benefício econômico que a consideração do chamado efeito arco pode proporcionar aos projetos de estruturas de suporte em concreto armado para edifícios de alvenaria estrutural. Após uma revisão bibliográfica e exposição teórica dos princípios do assunto, três edifícios reais são estudados, empregando-se o Método dos Elementos Finitos. Para cada exemplo, dois modelos de cálculo distintos são desenvolvidos: o tradicional, que ignora o efeito arco, e aquele que o considera. No caso dos modelos que consideram o efeito arco, as concentrações de tensões de compressão nas paredes, nas proximidades dos apoios, são verificadas quanto à segurança estrutural. Então, as vigas de suporte são dimensionadas de acordo com os dois modelos de cálculo, e os resultados obtidos são comparados do ponto de vista dos esforços solicitantes nas vigas, deslocamentos, armaduras dimensionadas e quantidades de materiais necessários. Finalmente, para ambas as soluções, para cada um dos três edifícios, as estruturas de suporte tem seus custos de construção avaliados e comparados, de forma a se evidenciar o benefício da consideração do efeito arco.

This work deals with the assessment of the potential economic benefit that the consideration of the so-called arch effect can provide to the design of support reinforced concrete structures for structural masonry buildings. After a literature review, some theoretical fundamentals on the studied subject are presented and three real building cases are studied using the Finite Elements Method. For each building case, two different numerical models are used: the regular one, without the arch effect, and the model that takes it into account. When the arch effect is considered, the regions subjected to compressive stress concentrations are checked in order to verify the structural safety. As for the support beams, the internal forces are obtained and the beams are dimensioned considering both the described numerical models. Then the obtained results are compared, focusing on internal forces, displacements and consumption of materials. Finally, for each studied case and for both numerical models used the construction costs are evaluated and compared in order to demonstrate the benefit of the arch effect consideration.

A partir da teoria de resposta linear (formalismo de Kubo) calculamos a condutividade de spin \σ_^ para um gás bidimensional de elétrons formado num poço quântico com duas subbandas devido a atuação de um novo tipo de interação spin-órbita [Bernardes et al. \it{Phys. Rev. Lett.} , 076603 (2007) \\& Calsaverini \it{et al}. \it{Phys. Rev. B} , 155313 (2008)]. Este novo termo é não-nulo mesmo em estruturas simétricas e surge devido ao acoplamento entre os estados confinados no poço de paridades diferentes. Encontramos um valor para \σ_^ não-nulo e não-universal (dependente da intensidade do acoplamento \η) quando somente uma das subbandas está ocupada, ao contrário de Rashba. Para encontrarmos valores realistas para \σ_^, determinamos \η via cálculo autoconsistente. Esse cálculo é executado para diferentes valores de densidade eletrônica em poços simples e duplos. Obtivemos que \σ_^ possui um comportamento não-monótono e sofre inversão de sinal como função da energia de Fermi (densidade de elétrons) conforme ela varia entre as duas subbandas. Contudo nossos resultados indicam que a condutividade Hall de spin é muito pequena \ ≤ ft(``\\ll \\frac{8\π}ïght) nesses sistemas (poços simples e duplos) e possivelmente não mensurável.

Using the Kubo linear response theory, we investigate spin Hall conductivity \σ_^ in a two-dimensional electron gas in quantum wells with two subbands, when intersubband-induced spin-orbit coupling is operative [Bernardes et al. \it{Phys. Rev. Lett.} , 076603 (2007) \\& Calsaverini \it{et al}. \it{Phys. Rev. B} , 155313 (2008)]. This new spin-orbit term is non-zero even in symmetric structures and it arises from the distinct parity of the confined states. We find non-zero and non-universal \σ_^ (dependent on spin-orbit coupling strength \η) when only one of the subbands is occupied. This is in contrast to the Rashba spin-orbit interaction for which \σ_^ is identically zero. To obtain realistic values for \σ_^, we develop a self-consistent scheme to calculate \η. We performed this calcultion for different values of the eletronic density in single and double wells. We find that \σ_^ shows a non-monotonic behavior and a sign change as the Fermi energy (carrier density) varies between the two subband edges. However, our results indicate that \σ_^ is extremely small \ ≤ ft(``\\ll \\frac{8\π}ïght) and possibly not measurable.

▼ Hayatın her alanında olduğu gibi edebiyat alanında da farklı ulusların edebiyatları arasındaki etkileşim kaçınılmazdır. Türk edebiyatı bağlamında bakıldığında özellikle Tanzimat Dönemi’nde (1839-1895) çeviri aracılığı ile yoğunlaşan genelde Batı-Türk, özelde ise Fransız-Türk edebiyatları arasındaki etkileşim süreci dönem dönem etki derecesi ve yönü değişse de 1800’lü yılların ortalarından bu yana süregelmiştir. Fransız edebiyatının Türk edebiyatı üzerindeki etkisi sonucunda üretilen ilk eserin Şinasi’nin Şair Evlenmesi adlı tiyatro eseri olması bu çalışma açısından önem taşımaktadır. Ancak Türk Tiyatrosu üzerindeki etkiler yalnızca Fransız Tiyatrosu’ndan yansımalar ile sınırlı kalmaz. 1970’li yıllarda, henüz 1920’lerde Alman tiyatro yazarı Bertolt Brecht’in geliştirdiği Epik Tiyatro’nun yine çeviri yolu ile Türk oyun yazarlarına ulaşması o dönemde başta Haldun Taner olmak üzere bir çok yazarın aynı türde oyunlar yazması ile sonuçlanır. Aynı dönemde Türk Tiyatrosu üzerinde Absürt Tiyatro adı altında Batı’da 1950’lerde ortaya çıkmış olan bir başka gelenek de etkilerini göstermeye başlar. Bu çalışma da genel olarak 1970 sonrasında Türk Tiyatrosu üzerinde Absürt Tiyatro’nun etkilerini, özelde ise Batı’daki ilk örneklerden birebir yansımaları; oyunlar arasındaki benzerlikler yanında sosyo-politik ve ekonomik arka plandan kaynaklanan farklılıkları irdelemeyi amaçlamaktadır. Genel olarak 1970’li yıllardan itibaren (neredeyse her on yılda bir gerçekleşen ihtilallerle paralel olarak) onar yıllık aralarla toplamda yedi yazarın on dört oyununun eklektik yöntemle çok boyutlu olarak ele alındığı çalışma, farklı kültürlere ait çalışmaları benzerlik ve farklılıkları ve bunların nedenleri bakımından karşılaştırarak Karşılaştırmalı Edebiyat Bilimi’ne de katkı sunma çabasındadır. Sonuç olarak, Batı edebiyatı içinde doğup gelişen Absürt Tiyatro geleneğinin 1970’li yıllardan itibaren Türk Tiyatrosu’nu yoğun olarak etkilediği; ancak oyunlar arasında Absürt Tiyatro özellikleri bakımından benzerlikler olmasına rağmen, son derece farklı siyasal, toplumsal ve ekonomik koşullar nedeniyle Türk tiyatro yazarlarının eserlerinde, bazen açık bazen örtük olarak oyunların yazıldığı dönemin arka planına ve sorunlara yer verdiği gözlenmektedir. Bunun yanısıra, Türk oyun yazarlarının oyunlarını sadece Absürt Tiyatro özellikleri ile sınırlandırmadığı; Epik Tiyatro, gerçeküstü özellikler, köy seyirlik oyunları gibi türler, akımlar ve teknikler ile -tam bir ortaklık göstermese de- farklı dönemlerde oyunlara farklı şekillerde zenginlik kattıkları ve aslında sentez oyunlar yarattıkları görülür. Bu çalışmanın Türk Tiyatrosu’na en önemli katkısı bazı araştırmacılar tarafından “çorak ve tüketilmiş” hatta “dönemini kapatmış” bir konu olarak görülen Absürt Tiyatro konusuna Türk Tiyatrosu bağlamında yeni bir soluk getirmek ve bu alanda yapılacak yeni çalışmaları teşvik etmek olacaktır.

▼ Semiconductor nanowires combine the material properties of semiconductors, which are ubiquitous in modern technology, with nanoscale dimensions and as such, are firmly poised at the forefront of nanotechnology research. The rich physics of semiconductor nanowire optics, in particular, arises from the increased interaction between light and matter that occurs when light is confined to dimensions below the size of its wavelength, in other words, when the nanowire serves as a light trapping optical cavity, which itself is also a source of light. Light confinement is taken to new extremes by coupling to the surface plasmon modes of metallic nanostructures, where light acquires mixed photonic and electronic character, and which may focus light to deep-subwavelength regions amenable to the dimensions of the electron wave. This thesis examines how the integration of "plasmonic optical cavities" and semiconductor nanowires leads to substantial modification (and enhancement) of the optical properties of the same, resulting in orders-of-magnitude faster and more efficient light emission with colors that may be tuned as a function of optical cavity geometry. Furthermore, this method is applied to nanowires composed of both direct and indirect bandgap semiconductor materials resulting in applications such as light emission from high-energy states in light emitting materials, highly enhanced broadband light emission from nominally non-light emitting (dark) materials, and broadband (and anomalous) enhancement of light absorption in various materials, all the while maintaining the unifying theme of employing integrated plasmonic-semiconductor optical cavities to achieve tailored optical properties. We begin with a review of the electromagnetic properties of optical cavities, surface plasmon-enhanced light emission in semiconductors, and the key physical properties of semiconductor nanowires. It goes without saying that this thesis work resides at the interface between optical physics and materials science.

▼ To help mitigate the escalating prevalence of Type 2 Diabetes (T2D) and alleviate society of its associated morbidity and economic burden on health care, it is crucial to understand its aetiology. Both genetic and the environmental risk factors are known to be involved. Healthy diets have been proven to reduce the risk of T2D in primary prevention trials, however, which components and exact mechanisms are involved is not fully understood, in particular, the role of macronutrient intake. Body weight, glycaemic markers and T2D are all to some extent genetically regulated. There may also be genetic influences on how people digest, absorb or metabolise macronutrients. This poses the possibility that the interplay between genes and our diet may help us unravel T2D’s aetiology. The aim of this PhD was to investigate gene-diet interactions on the risk of incident T2D, focusing primarily on macronutrient intake as the dietary factor. First, I systematically evaluated the current evidence before taking a step-wise approach (hypothesis driven to hypothesis-free) to interrogate gene-macronutrient interactions. This identified 13 publications, with 8 unique interactions reported between macronutrients (carbohydrate, fat, saturated fat, dietary fibre, and glycaemic load derived from self-report of dietary intake and circulating n-3 polyunsaturated fatty acids) and genetic variants in or near TCF7L2, GIPR, CAV2 and PEPD (p < 0.05) on T2D. All studies were observational with moderate to serious risk of bias and limitations that included lack of adequate adjustment for confounders, lack of reported replication and insufficient correction for multiple testing. Second, these reported interactions did not replicate in a large European multi-centre prospective T2D case-cohort study called EPIC-InterAct. We concluded that the heterogeneity between our results and those published could be explained by methodological differences in dietary measurement, population under study, study design and analysis but also by the possibility of spurious interactions. Third, given the paucity of gene-macronutrient interaction research using genetic risk scores (GRS), we examined the interaction between three GRS (for BMI (97 SNPs), insulin resistance (53 SNPs) and T2D (48 SNPs)) and macronutrient intake (quantity and quality indicators) in EPIC-InterAct. We did not identify any statistically significant interactions that passed multiple testing corrections (p≥0.20, with a p value threshold for rejecting the null hypothesis of 0.0015 (based on 0.05/33 tests)). We also examined 15 foods and beverages identified as being associated with T2D, and no significant interactions were detected. Lastly, we applied a hypothesis-free method to examine gene-macronutrient interactions and T2D risk by using a genome-environment-wide-interaction-study. Preliminary findings showed no significant interactions for total carbohydrate, protein, saturated fat, polyunsaturated fat and cereal fibre intake on T2D. In conclusion, the consistently null findings in this thesis…

▼ Numerical simulations of fluid-structure interaction (FSI) problems were performed in an effort to verify and validate a commercially available FSI tool. This tool uses an iterative partitioned coupling scheme between CD-adapco's STAR-CCM+ finite volume fluid solver and Simulia's Abaqus finite element structural solver to simulate the FSI response of a system. Preliminary verification and validation work (VandV) was carried out to understand the numerical behavior of the codes individually and together as a FSI tool. Verification and Validation work that was completed included code order verification of the respective fluid and structural solvers with Couette-Pouiselle flow and Euler-Bernoulli beam theory. These results confirmed the 2nd order accuracy of the spatial discretizations used. Following that, a mixture of solution verifications and model calibrations was performed with the inclusion of the physics models implemented in the solution of the FSI problems. Solution verifications were completed for fluid and structural stand-alone models as well as for the coupled FSI solutions. These results re-confirmed the spatial order of accuracy but for more complex flows and physics models as well as the order of accuracy of the temporal discretizations. In lieu of a good material definition, model calibration is performed to reproduce the experimental results. This work used model calibration for both instances of hyperelastic materials which were presented in the literature as validation cases because these materials were defined as linear elastic. Calibrated, three dimensional models of the bow seal on the University of Michigan bow seal test platform showed the ability to reproduce the experimental results qualitatively through averaging of the forces and seal displacements. These simulations represent the only current 3D results for this case. One significant result of this study is the ability to visualize the flow around the seal and to directly measure the seal resistances at varying cushion pressures, seal immersions, forward speeds, and different seal materials. SES design analysis could greatly benefit from the inclusion of flexible seals in simulations, and this work is a positive step in that direction. In future work, the inclusion of more complex seal geometries and contact will further enhance the capability of this tool. Advisors/Committee Members: Neu, Wayne L. (committeechair), McCue-Weil, Leigh S. (committee member), Yim, Solomon C. (committee member), Roy, Christopher John (committee member).

▼ Dramatic choices are the core of the content in contemporary adventure games like those produced by Telltale Games and Dontnod Entertainment, developers of the Life is Strange series. These consist of emotionally-charged and dramatically contextualized player choices rather than strategic or skill-based challenges. Current approaches to understanding and assessing player experience in these games include surveys, interviews, think-aloud and various biometric measurements. These measures, taken alone, are useful for understanding traditional gameplay challenges such as platformers or puzzles but fall short of assessing how emotional content influences player experience or leads to variations in player responses. I collaboratively conducted a study of six players playing the first episode of The Wolf Among Us (TWAU) by Telltale Games, recording gameplay and facial expressions along with heart rate and skin conductivity. To compare and analyze player responses and classify content features, I developed an encoding, the Interactive Cinematic Experience (ICE) schemata, and used it to annotate player traversals with feature locations and player choices. These align player response data to content for comparison and analysis. Researchers can use the model to compare multiple paths through the game that can span hours of gameplay. In order to understand the dataset better, I developed a web-based visual data mining tool, Sherlock, for annotating and analyzing player experience datasets using the schemata and assessed it with a group of game researchers. I compare the encoding method to two other encodings using content from TWAU: Elson's Story Intention Graphs and Mawhorter's choice poetics. Analyzing facial expressions using ICE for the first three chapters revealed a spectrum of variations in responses to content, supporting the presence and effectiveness of emotional content anchors and the characteristics of what I call the Telltale effect. Thematic content that depended on choices differed in the values portrayed from content that was always included. The approach of using multiple player responses, especially facial expression analytics, is essential to a "medium read" of experiences and is a promising direction for interactive narrative research using existing commercial storygame content.

Mestrado em Educação e Sociedade

O estudo que apresentamos analisa o caso de dois alunos com um passado de insucesso escolar e que inverteram suas trajectórias de vida escolar para o sucesso escolar. Tem como principal objectivo investigar a influência da interacção professor-aluno e as expectativas do professor – efeito Pigmalião na produção do desempenho escolar. No processo de investigação utilizou-se a metodologia qualitativa interpretativa por se tratar de histórias de vida (re)contadas por diversos actores (aluno, pais, professores, etc). A pesquisa desenvolveu-se em duas escolas de 1º Ciclo: uma em Portugal do Ensino Básico e outra no Brasil do Ensino Fundamental, frequentadas por alunos pertencentes às classes sociais desfavorecidas. Os dados da pesquisa foram obtidos através de uma grande diversidade de fontes: entrevistas, documentos oficiais das escolas e dos alunos, fichas de avaliação, textos escritos pelos alunos, relatórios, relatos, conversas informais e notas de trabalho de campo. De um modo geral, verifica-se que os dois casos de estudo apresentam pontos de similitude de opinião dos intervenientes no processo ensino-aprendizagem que, embora em continentes distantes com culturas distintas, não só identificam o “efeito professor” na produção do sucesso escolar como, também, apontam para este ser um factor decisivo na transformação do aluno. Verificou-se que a importância da relação professor-aluno que se estende à família (positivamente) e as expectativas do professor (que se reflectem no aluno e na família) contribuem para o sucesso escolar do aluno.

The study we present focuses on the cases of two students who lacked educational achievement and who were able to change their performance and to succeed. Its main goal is to analyse the implications of the teacher-student relationship and of the teacher‟s expectations – the Pygmalion effect towards the student‟s performance at school. A qualitative and interpretative methodology was used for analysing these cases, once we were dealing with life stories told and retold by different actors (student, parents, teachers, etc.). This research was developed in two elementary schools: one in Portugal and the other one in Brazil and which are attended by students who belong to low social settings. The data were obtained through a variety of sources: interviews, official documents from the school and from the students, assessments and texts written by students, reports, statements, informal talks and field study notes. In a general way, these two study cases show points of similarity in what concerns the interveners‟ opinion on the teaching and learning process. Although they live in distant continents with different cultures, they have not only identified “the teacher‟s effect” in their educational achievement at school but they have also mentioned it as a decisive factor for the student‟s transformation, It is clear that the importance of the teacher-student relationship which is seen in the family (in a positive way) and of the teacher‟s expectations…

▼ Magnetic cooling based on the magnetocaloric effect is topical for energy efficiency and environmental reasons. The MnCoGe family of compounds is promising for magnetic cooling which do not contain higher cost rare earths and can provide a working temperature range near room temperature. MnCoGe has two stable crystallographic structures, the low-temperature TiNiSi-type orthorhombic structure (Pnma, martensitic phase) and the high-temperature Ni₂In-type hexagonal structure (P6₃/mmc, austenitic phase). In this work, this martensitic transformation was adjusted by substitution of Fe or Ni for Mn or Co. Variable temperature x-ray diffraction, neutron diffraction and differential scanning calorimetry were used to determine the nature and position of the adjusted transitions. The magnetic properties in these compounds were studied by magnetisation and neutron diffraction experiments. Magnetocaloric effects were also explored.In as-prepared (Mn₁₋ₓFeₓ)CoGe (x = 0.01 to 0.04) and as-prepared Mn(Co₀․₉₆Fe₀․₀₄)Ge, the Fe substitution reduces the martensitic transformation temperature TM to near room temperature. Ferromagnetic structures with magnetic moments on the Mn sublattice along the cₒᵣth-axis are found in both (Mn₁₋ₓFeₓ)CoGe and Mn(Co₀․₉₆Fe₀․₀₄)Ge compounds below TM. The analysis of magnetisation measurements, plus variable temperature x-ray and neutron diffraction indicate that a magneto-structural transition exists in (Mn₁₋ₓFeₓ)CoGe (x = 0.01 to 0.03) and Mn(Co₀․₉₆Fe₀․₀₄)Ge. Large entropy changes via the magnetocaloric effect were observed near room temperature.⁵⁷Fe Mössbauer spectroscopy studies indicated that Fe is distributed on both the Mn and the Co sites with greater preference to occupy the Co site in both as-prepared (Mn₁₋ₓFeₓ)CoGe and Mn(Co₁₋ₓFeₓ)Ge, while some of the Fe moves from the Co site to the Fe site during annealing.In annealed (Mn₁₋ₓNiₓ)CoGe (x= 0.03 to 0.07) and annealed Mn(Co₀․₈₆Ni₀․₁₄)Ge, ferromagnetic structures with a magnetic moment on the Mn sublattice along the cₒᵣth-axis are obtained. However, analyses of neutron diffraction measurements point to the cₒᵣth-axis easy ferromagnetic and incommensurate magnetic structures with increasing Ni concentration in annealed Mn(Co₁₋ₓNiₓ)Ge (x = 0.4 to 1.0) compounds. Magneto-structural transitions form in annealed (Mn₁₋ₓNiₓ)CoGe (x= 0.03 and 0.04) and Mn(Co₁₋ₓNiₓ)Ge (x = 0.3 to 0.6). Conventional and/or inverse magnetocaloric effects are observed in these compounds.

▼ Charged particle dynamics can be altered considerably even by weak electromagnetic waves if some of the particles are in resonance. Depending on the wave parameters, the resonances in the phase space can either be well separated, in which case the particle dynamics is regular almost everywhere, or they can overlap leading to stochastic particle motion in a large volume of the phase space. Although different, both of these regimes allow one to manipulate particle ensembles by arranging resonant interactions with appropriate waves. This thesis is devoted to studying two wave-particle manipulation techniques having potential applications in fusion and laser-plasma interaction research. Specifically, we study the alpha-channeling effect (which relies on stochastic diffusion of resonant particles) and the so-called negative-mass effect (NME) (which involves the conservation of the adiabatic invariant). The alpha-channeling effect entails the use of radio-frequency waves to expel and cool high-energetic alpha particles born in a fusion reactor; the device reactivity can then be increased even further by redirecting the extracted energy to fuel ions. Recently, the alpha-channeling technique, originally proposed for tokamaks, was shown to be suitable for application in mirror machines as well. In the first part of this thesis, we deepen the understanding of issues and possibilities of the alpha-channeling implementation in open-ended reactors. We verify the feasibility of this technique and identify specific waves and supplementary techniques, which can potentially be used for implementing the alpha-channeling in realistic mirror devices. We also propose a new technique for using the alpha-channeling wave energy to catalyze fusion reaction by employing minority ions as a mediator species. In the second part of this thesis, the NME manifesting itself as an unusual response of a resonant particle to external adiabatic perturbations mimicking the behavior of a particle with a negative mass, is discussed. Using the Hamiltonian perturbation theory, the calculation of the effective parallel mass is extended to the non-vacuum waves and the NME is shown to be robust. Also, the consequences of radiation friction and collisions with the background particles on the NME are studied and new collective phenomena emerging in plasmas with negative-mass particles are considered.

▼ The topological insulator Bi2Te3 has been grown on Si(111)-(7 × 7) surface by molecular beam epitaxy. Reflection high energy electron diffraction, in situ scanning tunnelling microscopy, x-ray photoelectron spectroscopy and ex situ x-ray diffraction studies have been performed to analyze the quality of the growth. These analyses suggest a very good layer-by-layer epitaxial growth of Bi2Te3 on the atomically at Si surface. The magnetoresistance of the samples has been studied with magnetic field perpendicular and parallel to the sample surface, up to 9 T, over a temperature range of 2 K to 20 K. A sharp dip at low fields (0 T - 1 T) and near-linear behavior for high fields (> 4 T) have been observed in the perpendicular field magnetoresistance. The low field dip is due to weak antilocalization that agrees well with the simplified Hikami-Larkin-Nagaoka model. It has been demonstrated that both the low field dip and the high field near-linear behavior can be explained by the original Hikami-Larkin-Nagaoka formula alone in a system with strong spin-orbit coupling. From the fitting of the perpendicular field magnetoresistance the phase coherence length, the mean free path and the spin-orbit relaxation time have been estimated. The phase coherence length shows power law dependence with temperature indicating two dimensional nature of the transport. The power law also suggests electron electron interaction as the prominent dephasing mechanism. The out-of-plane spin-orbit relaxation time is determined to be small and the in-plane spin-orbit relaxation time is found to be comparable to the momentum relaxation time. The estimation of these charge and spin transport parameters is useful for topological insulator based magneto electric device applications. It also has been shown that the strong spin-orbit coupling suppresses the Zeeman contribution in perpendicular field magnetoresistance. The logarithmic divergence of perpendicular field magnetoresistance with temperature for low temperature range (2 K - 20 K) at high fields shows the presence of Coulomb interaction in the spin singlet channel. For magnetoresistance with the field parallel to the sample surface, the observed magnetoresistance has parabolic dependence for small fields (0 T - 0.6 T) and logarithmic dependence for large fields (> 3 T), which is due to the Zeeman effect. It is found that the data are inconsistent with only the Maekawa and Fukuyama theory of non interacting electrons with Zeeman contributions to the transport, but are consistent with theory if one also takes into account the electron electron interaction and the Zeeman splitting term in the electron electron interaction theory of Lee and Ramakrishnan. The Zeeman g-factor and the strength of Coulomb scattering due to electron electron interaction have been estimated from fitting of the parallel field magnetoresistance. The magnetoresistance also shows anisotropy with respect to the field directions. The angle dependent anisotropic magnetoresistance can be fitted well by the original HLN theory alone.… Advisors/Committee Members: Banerjee, Sanjay (advisor).
