▼ Esta tese versa sobre os produtos de Stratonovich e de Berezin de funções na esfera \'S POT. 2\'. Cada um destes produtos é definido atravéz de uma correspondência de símbolos, que é uma aplicação linear bijetiva entre operadores lineares num espaço de Hilbert complexo de dimensão n + 1, ou seja matrizes complexas (n + 1) × (n + 1), e polinômios complexos de grau próprio n definidos na 2-esfera, PolyC(\'S POT. 2\')n, satisfazendo algumas propriedades básicas, como equivariância pela ação do grupo de rotações SO(3), preservação das estruturas reais e normalização [12]. Mais geralmente, toda correspondência define um produto associativo mas não comutativo em PolyC(\'S POT. 2\')n induzido do produto de operadores, chamado de produto twisted em PolyC(\'S POT. \'2)n. Cada um destes produtos twisted, por sua vez, pode ser escrito na forma integral f g(n) = \'INT. INF. S POT. 2 X \'S POT. 2f́(\'n IND. 1\'\') g (\'n IND. 2\'), n) L (\'n IND. 1\', \'n IND.2\', n) \'dn IND.1\́'dn IND. 2, onde f, g PolyC(\'S POT. 2)n, \'n IND. 1\',ń IND. 2\', n \'S POT. 2\'. Em tal representação integral, todas as propriedades do produto twisted são convertidas em propriedades do trikernel integral L : \'S POT. 2 ́× \'S POT. 2�́� \'S POT. 2 ́C. Os produtos twisted estudados nesta tese são os produtos induzidos pela correspondência padrão de Stratonovich e a correspondência padrão de Berezin, respectivamente, que num certo limite assintótico 2j = n definem deformações estritas da álgebra de Poisson de \'S POT. 2[́12]. Para cada um deste dois produtos, denotados por \'n SOB. 1é \'n SOB. bŕespectivamente, seu trikernel integral é denotado por L \'SOB. j 1 ́e L \'j SOB. ~b, respectivamente. A primeira parte desta tese consistiu em desenvolver fórmulas mais tratáveis para L \'j SOB. 1é L j SOB. bńos casos de número de spin j = 1/2, 1, 3/2, 2, fórmulas estas escritas em termos de funções de dois e de três pontos, invariantes por SO(3), como produtos escalares e determinantes. Nossa esperança inicial era de que pudéssemos encontar padrões que nos permitissem inferir fórmulas fechadas para cada um destes trikernels, válidas para qualquer j, ou pelo menos que nos permitissem inferir fórmulas assintóticas para estes trikernels quando 2j = n . Porém, o grau de complexidade das fórmulas desenvolvidas se mostrou fortemente crescente com j, frustrando nossas expectativas iniciais. Partimos então para uma exploração preliminar de um tipo de aproximação assintótica destes produtos de certas funções oscilatórias na esfera. Mais precisamente, na segunda parte desta tese, preparamos e estudamos preliminarmente o produto de Stratonovich e o produto de Berezin (assim como o produto pontual) de dois harmônicos esféricos, \'Y POT. m1 INF. l1é \'Y POT. m2 INF. l2 PolyC(\'S POT. 2\')n, no limite assintótico quando tanto \'l IND. 1 ́como \'l IND. 2 ́tendem a infinito linearmente com n (mantendo \'l IND. i ́ n).

▼ Seit der ersten Isolierung durch Geim und Novoselv im Jahr 2004 hat sich Graphene schnell in ein eigenständiges Forschungsfeld innerhalb der Physik der kondensierten Materie entwickelt, zu dem bereits Tausende von Publikationen zählen. Dieses Material hat große Aufmerksamkeit auf sich gezogen, nicht nur weil es echt zweidimensional ist – eine Besonderheit, die lange als unmöglich galt – aber auch weil es der erste Stellvertreter einer neuen Klasse von Materialien ist, deren elektronisches Spektrum linear um isolierte Punkte in der Brillouin Zone dispersiert, den Dirac-Materialien. Eine ungewöhnliche Folge der linearen Energie-Impuls Dispersion ist der Kollaps der Fermi-Fläche auf isolierte Punkte im ladungsneutralen Fall, begleitet von einer verschwindenden Zustandsdichte. Während es diese Eigenschaft des nichtwechselwirkenden Modells ist, welche Graphen von anderen, konventionellen kondensierte Materie Systemen unterscheidet, so führt sie zu schwerwiegenden Komplikationen bei der Berechnung physikalischer Observablen, sollte das Modell um Zweiteilchen-Wechselwirkungen und/oder Unordnung erweitert werden. In dieser Dissertation betrachten wir beide Fälle separat. Nachdem wir die Niedrigenergie-Quantenfeldtheorie aus einem Tight-Binding-Modell abgeleitet und die Einteilchen-irreduziblen (1PI) Vertex-Funktionen als fundamentale Bausteine der Korrelationsfunktionen etabliert haben, konstruieren wir einen nicht-perturbativen Formalismus für die Berechnung eben dieser Vertex-Funktionen auf Basis der funktionalen Renormierungsgruppe (fRG). In Kombination mit dem Keldysh-Formalismus, erlaubt es dieser Formalismus sowohl Gleichgewichts- als auch Nichtgleichgewichtsprobleme zu behandeln. Um einige technische Probleme der fRG in ihrer Standardformulierung zu umgehen, die bei der Behandlung fermionischer Systeme bei endlicher Dichte auftreten, untersuchen wir auch eine Variation der fRG, bei der das chemische Potential als Flussparameter interpretiert wird. Wir erhalten hierarchische Gleichungssysteme, welche die Änderung der 1PI-Vertex-Funktionen unter Variation einer künstlichen Cutoff Skale beziehungsweise des chemischen Potentials beschreiben. Diese nicht-perturbativen Formalismen werden zur Berechnung der Renormierung der Fermigeschwindigkeit und der statischen dielektrischen Funktion bei endlicher Temperatur und Dichte im Regime starker Kopplung verwendet. Da es sich bei der Keldysh-fRG um eine exakte Formulierung von Quantenfeldtheorie handelt, sollte es möglich sein mit ihrer Hilfe den fraktionierten Quanten-Hall-Effekt zu beschreiben. Mit den derzeitig verfügbaren Trunkierungsschemata gelingt es jedoch nicht die notwendigen nicht-trivialen Korrelationen mit einzubeziehen, um diesen Effekt zu beschreiben. Um dieses Problem zu umgehen betrachten wir eine modifizierte Feldtheorie, bei der diese Korrelationen ``von Hand'' durch ein Chern-Simons Feld implementiert werden, welches zusätzlich zur Coulomb Wechselwirkung an die Fermionen koppelt. Diese modifizierte Feldtheorie wird in Sattelpunktsnäherung mit Gauß'schen… Advisors/Committee Members: male (gender), Brouwer, Piet W. (firstReferee), von Oppen, Felix (furtherReferee).

▼ Magneto-electro-elastic materials can convert energies from one form to the other among the mechanical, electric and magnetic ones, and thus they have potential applications in clean energy harvest, various sensors, actuators and other hi-tech areas. Analytical solutions are of great importance to analyze behaviors of magneto-electro-elastic materials, especially for magneto-electro-elastic bi-materials whose interface could substantially influence behaviors of the whole material. The extended Stroh formalism and Fourier transformation are adopted to derive the fundamental solutions in a three-dimesional magneto-electro-elastic bi-material. The solutions are in a line integral form. Responses on the interface are investigated. In terms of geometric domains, the obtained analytical solutions can be reduced to the ones in half space and homogeneous full space. In terms of material properties, the obtained solutions can be reduced to the ones in decoupled cases such as piezoelectric, piezomagnetic or elastic materials. Interfacial cracks with impermeable conditions on crack faces in three-dimensional magneto-electro-elastic as well as two-dimensional piezoelectric bi-materials are investigated. A numerical scheme based on the Crouch-type fundamental solutions and the extended displacement-discontinuity method is defined for analyzing interfacial cracks. The physically unreal oscillating singularity at the interfacial crack tip or front is avoided by replacing the delta expression with the distribution function in the solutions. The influence of this replacement and the effect of the Gaussian parameter on predicting fracture parameters are examined numerically. Electric and magnetic nonlinearities at interfacial crack fronts in a magneto-electro-elastic bi-material are considered by adopting the electric-magnetic polarization saturation model. In this model, the perfect electric displacement and magnetic induction saturations are assumed. Green’s functions for the ring element of uniform extended displacement discontinuities are derived to form the system of equations in the extended displacement discontinuity method. The unknown sizes of the electric and magnetic saturation zones are determined by the vanishing of the electric displacement and magnetic induction intensity factors at corresponding crack fronts. An iteration approach is designed to solve for the two unknown sizes. The effect of the electric/magnetic field on the saturation zones as well as the influence of the saturation zones on the stress intensity factor is discussed.

Les opérateurs de Berezin – Toeplitz permettent de quantifier des fonctions, ou des symboles, sur des variétés kähleriennes compactes, et sont définies à partir du noyau de Bergman (ou de Szeg\H{o}). Nous étudions le spectre des opérateurs de Toeplitz dans un régime asymptotique qui correspond à une limite semiclassique. Cette étude est motivée par le comportement magnétique atypique observé dans certains cristaux à basse température. Nous étudions la concentration des fonctions propres des opérateurs de Toeplitz, dans des cas où les effets sous-principaux (du même ordre que le paramètre semiclassique) permet de différencier entre plusieurs configurations classiques, un effet connu en physique sous le nom de sélection quantique Nous exhibons un critère général pour la sélection quantique et nous donnons des développements asymptotiques précis de fonctions propres dans le cas Morse et Morse – Bott, ainsi que dans un cas dégénéré. Nous développons également un nouveau cadre pour le traitement du noyau de Bergman et des opérateurs de Toeplitz en régularité analytique. Nous démontrons que le noyau de Bergman admet un développement asymptotique, avec erreur exponentiellement petite, sur des variétés analytiques réelles. Nous obtenons aussi une précision exponentiellement fine dans les compositions et le spectre d'opérateurs à symbole analytique, et la décroissance exponentielle des fonctions propres.

Berezin-Toeplitz operators allow to quantize functions, or symbols, on compact Kähler manifolds, and are defined using the Bergman (or Szeg\H{o}) kernel. We study the spectrum of Toeplitz operators in an asymptotic regime which corresponds to a semiclassical limit. This study is motivated by the atypic magnetic behaviour observed in certain crystals at low temperature. We study the concentration of eigenfunctions of Toeplitz operators in cases where subprincipal effects (of same order as the semiclassical parameter) discriminate between different classical configurations, an effect known in physics as quantum selection . We show a general criterion for quantum selection and we give detailed eigenfunction expansions in the Morse and Morse-Bott case, as well as in a degenerate case. We also develop a new framework in order to treat Bergman kernels and Toeplitz operators with real-analytic regularity. We prove that the Bergman kernel admits an expansion with exponentially small error on real-analytic manifolds. We also obtain exponential accuracy in compositions and spectra of operators with analytic symbols, as well as exponential decay of eigenfunctions.

Les fonctions polyanalytiques entières généralisent les fonctions entières dans la mesure où elles sont les solutions sur le plan complexe ℂ de l'équation de Cauchy-Riemann à l'ordre n, de la forme { partial} nf / \partial z̅ n = 0. Un espace de Fock polyanalytique F2 {α,n} est, par analogie avec le cas classique, le sous-espace fermé de l'espace de Hilbert L² (ℂ,dμ α), où μ α est une mesure de probabilité gaussienne sur ℂ de paramètre alpha>0, formé des fonctions polyanalytiques entières d'ordre n. L'objet de cette thèses est l'étude d'éléments classiques de la théorie des opérateurs tels que la transformée de Berezin et les opérateurs de Toeplitz dans le cadre particulier des espaces de Fock polyanalytiques. Dans ce manuscrit, il est montré en particulier que les points fixes de la transformée de Berezin qui appartiennent aux espaces de Lebesgue sont les fonctions nulles ou éventuellement constantes. Concernant les opérateurs de Toeplitz, le problème de Sarason est étudié. Etant donné une fonction f, l'opérateur de Toeplitz de symbole f est formellement défini par T {alpha,n} f(h)=P {alpha,n}(f h), où P {alpha,n} est la projection orthogonale de L²(ℂ,dμ α) sur F² {alpha,n}. Le problème de Sarason consiste à donner une condition nécessaire et suffisante sur f et g pour que le produit d'opérateurs de symboles f et bar g soit continu

Entire polyanalytic functions generalize entire functions in that they are solutions of "Cauchy-Riemann equations of order n, of the form {\partial}ⁿ f / \partial z̅ⁿ = 0, over the whole complex plane ℂ. Polyanalytic Fock space F²_α,n is, by analogy with the classical case, the closed subspace of the Hilbert space L²(ℂ,dμ_α), where μ_α is a Gaussian probability measure over ℂ with weight α>0, of polyentire functions of order n. The aim of this PhD thesis is the study of classical objects of operator theory such that the Berezin transform and Toeplitz operators in the particular case of polyanalytic Fock spaces. In this written, it is shown among other results, that the L^p fixed points of the Berezin transform are constant functions. Concerning Toeplitz operators, the Sarason problem is studied. Given a function f, the Toeplitz operator with symbol f is formally defined by Tⁿ_f(h)=P_{F²_n}(f h), where P_{F²_n} is the orthogonal projection from L²(ℂ,dμ) on to F²_n. The so-called Sarason's problem consists in finding necessary and sufficient conditions on the symbols f and g for the Toeplitz product with symbols f and \bar g to be bounded in the Fock space.

This approach extends the standard family of Jacobi polynomials to a new class of fractional orthogonal functions, namely Jacobi Polyfractonomials and tempered Jacobi Polyfractonomials, which enjoy many attractive properties. We introduce these fractional eigenfunctions as optimal basis/test functions in developing high-order Petrov Galerkin spectral/spectral-element methods for fractional ODEs/FPDEs. In addition to their high accuracy and ability to capture singularities, our numerical schemes rigorously generalize the existing standard spectral methods for PDEs to FPDEs. Next, for fast treatment of nonlinear and multi-term FPDEs such as fractional Burgers equation, we develop a new spectral method, called the fractional spectral collocation method, which introduces a new class of fractional Lagrange interpolants. For simulation of multi-dynamics systems, we also propose that by varying the differential order of a given governing equation as a function of space and/or time, we can capture a wide range of dynamics from diffusion to sub-diffusion or from wave dynamics transitioning back to diffusion. For such variable-order and distributed-order FPDEs, we have developed two fast and spectrally accurate numerical algorithms. In addition, while almost all existing methods for FPDEs are applicable only in one- or at most two-dimensional problems, we develop a unified Petrov-Galerkin spectral method that solves elliptic, hyperbolic, and parabolic FPDEs in high dimensions. We also formulate an implicit explicit (IMEX) splitting scheme for simulation of stiff problems. Moreover, we construct an implicit-explicit (IMEX) scheme of an observable second order accuracy. We employ this scheme to solve a system of Keller-Segel chemotaxis FPDEs as a biological application. Finally, we formulate a family of fractional modal expansions for non-tensorial domains such as triangle and tetrahedral elements. We test the approximability of such fractional basis function by carrying out Galerkin projection in simplex domain. This framework will be employed for efficient treatment of FPDEs in complex geometries in future.

Cette thèse montre en quoi la quantification de Berezin – Toeplitz peut être incorporée dans le cadre de la géométrie non commutative.Tout d'abord, nous présentons les principales notions abordées : les opérateurs de Toeplitz (classiques et généralisés), les quantifications géométrique et par déformation, ainsi que quelques outils de la géométrie non commutative.La première étape de ces travaux a été de construire des triplets spectraux (A,H,D) utilisant des algèbres d'opérateurs de Toeplitz sur les espaces de Hardy et Bergman pondérés relatifs à des ouverts Omega de Cn à bord régulier et strictement pseudoconvexes, ainsi que sur l'espace de Fock sur Cn. Nous montrons que les espaces non commutatifs induits sont réguliers et possèdent la même dimension que le domaine complexe sous-jacent. Différents opérateurs D sont aussi présentés. Le premier est l'opérateur de Dirac usuel sur L2(Rn) ramené sur le domaine par transport unitaire, d'autres sont formés à partir de l'opérateur d'extension harmonique de Poisson ou de la dérivée normale complexe sur le bord de Omega.Dans un deuxième temps, nous présentons un triplet spectral naturel de dimension n+1 construit à partir du produit star de la quantification de Berezin – Toeplitz. Les éléments de l'algèbre correspondent à des suites d'opérateurs de Toeplitz dont chacun des termes agit sur un espace de Bergman pondéré. Plus généralement, nous posons des conditions pour lesquelles une somme infinie de triplets spectraux forme de nouveau un triplet spectral, et nous en donnons un exemple.

The results of this thesis show links between the Berezin – Toeplitz quantization and noncommutative geometry.We first give an overview of the three different domains we handle: the theory of Toeplitz operators (classical and generalized), the geometric and deformation quantizations and the principal tools we use in noncommutative geometry.The first step of the study consists in giving examples of spectral triples (A,H,D) involving algebras of Toeplitz operators acting on the Hardy and weighted Bergman spaces over a smoothly bounded strictly pseudoconvex domain Omega of Cn, and also on the Fock space over Cn. It is shown that resulting noncommutative spaces are regular and of the same dimension as the complex domain. We also give and compare different classes of operator D, first by transporting the usual Dirac operator on L2(Rn) via unitaries, and then by considering the Poisson extension operator or the complex normal derivative on the boundary.Secondly, we show how the Berezin – Toeplitz star product over Omega naturally induces a spectral triple of dimension n+1 whose construction involves sequences of Toeplitz operators over weighted Bergman spaces. This result led us to study more generally to what extent a family of spectral triples can be integrated to form another spectral triple. We also provide an example of such triple.

Nous définissons et étudions dans cette thèse un formalisme permettant de traiter de questions tannakiennes pour des groupes définis sur des anneaux différentiels généralisés, qui généralisent à la fois les anneaux différentiels et les anneaux de différence. Nous définissons une notion de catégorie tannakienne différentielle de manière similaire au formalisme tannakien usuel, en ajoutant une structure supplémentaire permettant de décrire la structure induite par la différentielle généralisée. Nous étudions ensuite les propriétés modèle-théoriques des catégories qui en résultent, réalisant le groupe tannakien associé à la catégorie comme un groupe de liaison modèle-théorique. Dans le dernier chapitre, nous étudions la notion d'univers d'une structure du premier ordre, et introduisons une topologie dans ce contexte qui est réminiscente de la topologie des espaces de types en Théorie des Modèles du premier ordre. Nous étudions également la notion de groupoïde de liaison du point de vue des univers

In this thesis, we define and study a formalism which allows one to work on Tannakian questions for groups defined over generalized differential rings, which generalize both differential rings and difference rings. We define a notion of differential Tanakian category which is similar to the usual Tannakian formalism, adding a structure which permits to describe the differential structure induced by the generalized differential. We then study the model-theoretical properties of the resulting categories, realizing the Tannakian group associated to a category as a model-theoretical binding group. In the last chapter, we study the notion of universe associated to a first-order structure, and we introduce a topology in this context, which is reminiscent of the topology on the spaces of types in first-order Model Theory. We also study the notion of binding groupoid from the point of view of universes

▼ Modernism and the Narrative Cultures of Film treats writing about film as a literary genre unto itself, where authors spun self-reflexive fictions about the cinema that doubled as commentaries on their own novelistic experiments. For the early period of the twentieth century in which no definition of cinema was self-evident, each description of the medium assumed the speculative quality of a fiction. Reading literature by Virginia Woolf, H. D. and Henry Green alongside film reviews and treatises on aesthetics, I show that film offered a displaced figure for persistent questions about representation, psychology, and narrative omniscience. Cast alternately as a mechanized art of surfaces and as the ideal vehicle of subjectivity, as the epitome of aesthetic detachment and as the prime example of art's manifest entanglement in everyday life, film lent itself to rampant figuration, at once organizing and undoing the central antagonisms of modernist aesthetics. I argue that the mobile appropriation, affirmation, and disavowal of film by modernist writers provided ready occasions to rethink literary narration. Situating these writings within the chaotic debates about film as “art,” Modernism and the Narrative Cultures of Film shows that literary descriptions of cinema functioned as richly digressive allegories of narrative method, in which notions of subjectivity, language, and omniscience were reconfigured in the shadow of a medium that seemed to make those categories at once obsolete and newly urgent. As the works of Virginia Woolf, H. D., and Henry Green attest, such literary fables of cinematic meaning (and meaninglessness) harbored striking—if oblique—meditations on narrative innovation and its social content, seeking unlikely affinities between the apparent privacy of prose and the conjectural modes of spectatorship. Writing not out of a desire to imitate film but out of a need to address its aesthetic consequences, the writers I consider expressed their discontent with the individualism of the novel, exploring formal modes of collective dissidence and public fantasy.

▼ In this research, a bi-criteria batching and scheduling problem is investigated in hybrid flow shop environments, where unrelated-parallel machines are run simultaneously with different capacities and eligibilities in processing, in some stages. The objective is to simultaneously minimize a linear combination of the total weighted completion time and total weighted tardiness. The first favors the producer’s interest by minimizing work-in-process inventory, inventory holding cost, and energy consumption as well as maximizing machine utilization, while the second favors the customers’ interest by maximizing customers’ service level and delivery speed. In particular, it disregards the group technology assumptions (GTAs) by allowing for the possibility of splitting pre-determined groups of jobs into inconsistent batches in order to improve the operational efficiency. A comparison between the group scheduling and batch scheduling approaches reveals the outstanding performance of the batch scheduling approach. As a result, contrary to the GTAs, jobs belonging to a group might be processed on more than one machine as batches, but not all machines may be capable of processing all jobs. A sequence- and machine-dependent setup time is required between each of two consecutively scheduled batches belonging to different groups. Based on manufacturing company policy, the desired lower bounds on batch sizes are considered for the number of jobs assigned to batches. Although, the direction in which all jobs move through production line is the same, some jobs may skip some stages. Furthermore, to reflect real industry requirements, the job release times and the machine availability times are considered to be dynamic, which means not all machines and jobs are available at the beginning of the planning horizon. The problem is formulated with the help of four mixed-integer linear programming (MILP) models. Two out of four MILP models are formulated as two integrated phases, i.e., batching and scheduling phases, with respect to the precedence constraints between each pair of jobs/batches and/or the position concept within batches. The optimal combination between batch compositions of groups are determined in the batching phase, while the optimal assignment and sequence of batches on machines and sequence of jobs within batches are determined in the scheduling phase, with respect to a set of operational constraints. A batch composition of a group corresponding to a particular stage, determined in the batching phase of the MILP model, represents the number of batches assigned to the group as well as the number and type of jobs belonging to each batch of that group. Since the first and second MILP models lead to unmanageable solution space, the relaxed MILP model, which allocates one and only one job to each batch of each group in each stage, can be developed to focus on the non-dominated solution space. The optimal solutions of MILP models and relaxed MILP model are equal, if and only if the optimal solution of the relaxed MILP model does… Advisors/Committee Members: Logendran, Rasaratnam (advisor), Haapala, Karl (committee member).

▼ The current development technique for Bi-2212 multifilament superconducting wire is the oxide powder in tube process. For this process, phase pure Bi-2212 fine powder is loaded into a silver tube then drawn, stacked, and redrawn until the desired filament size and number is achieved. The wire is then cabled and wound onto its final form where it undergoes a partial melt heat treatment in an overpressure environment of 5 -10 MPa. The entire form is cooled in a controlled way to allow the liquid to recrystallize into phase pure Bi-2212. However, the partial melt heat treatment process leads to several difficulties. Small void spaces within the initial powder can coalesce into large bubbles after the heat treatment. These large bubbles can occlude any supercurrent from traveling along the filament. The melt liquid is also chemically aggressive and will etch and therefore weaken the silver matrix. Lastly, the recrystallized Bi-2212 is not textured and there is limited connectivity between individual crystal formations. Each of these difficulties need to be addressed simultaneously to optimize the performance of future Bi-2212 superconducting wires. A new method for preparing Bi-2212 multifilament wires is being developed to minimize the effects of the above mentioned difficulties. Fine Bi-2212 powder is homogenously mixed with nano-scale silver powder and uniaxially compressed into square cross section bars. The bars are loaded into a silver tube then drawn, stacked, and redrawn until the desired filament size and number is achieved. To avoid the complications of the partial melt heat treatment a non-melt heat treatment was developed. The non-melt heat treatment takes advantage of the material properties of the Bi-2212/silver interface. The bulk of the Bi-2212 is never melted, but interconnectivity and grain growth is still achieved. The cores used to fabricate the multifilament wires display significant superconductivity in liquid nitrogen, but the multifilament wires show no signs of superconductivity. Separate optimization of the wires in liquid helium is required to maximum the supercurrent carrying potential of the multifilament wires. Additional study on oxygen doping during the non-melt heat treatment may also be necessary.

Lors de ces dernières années les volumes de données analysées par les entreprises et les laboratoires de recherches ont fortement augment´es ouvrant ainsi l’`ere du BigData. Cependant ces données brutes sont fréquemment non catégorisées et difficilement exploitables. Cette thèse vise à améliorer et faciliter le pré-traitement et la comprehension de grands volumes de données en fournissant des algorithmes d’apprentissage non supervisés. La première partie de cette thèse est consacrée à un état de l’art des algorithmes de partitionnement et bi-partitionnement ainsi qu’une présentation des technologies du Big Data. La première contribution de cette thèse est dédiée à la conception de l’algorithme de clustering Self-Organizing Map ou carte auto-organisatrice [Kohonen,2001] dans un environnement Big data. Notre algorithme (SOM-MR) fournit les mêmes avantages que l’algorithme de base, à savoir la création de partition de données et leur visualisation sous la forme de carte. De plus il utilise la plateforme Spark, ce qui lui permet à la fois de traiter de grands volumes de données en peu de temps. De part la popularité de cette plateforme il s’intègre facilement dans dans de nombreux environnements de traitement de données. C’est ce que nous avons démontré dans notre projet “Square Predict” réalisé en partenariat avec l’assurance Axa. Ce projet avait pour objectif de fournir une plateforme d’analyse de données en temps r´eel afin d’évaluer la sévérité d’une catastrophe naturelle ou d’améliorer la connaissance des risques résidentiels. Durant ce projet nous avons démontré l’efficacité de notre algorithme pour analyser et fournir des visualisations à partir de grands volumes de données provenant des réseaux sociaux et d’Open data. La deuxième contribution de cette thèse est consacrée à un nouvel algorithme de BiClustering. Le BiClustering consiste `a réaliser un clustering simultanément sur les observations et les variables. Dans cette contribution nous proposons une nouvelle approche de biclustering bas´e sur l’algorithme self-organizing maps capable de passer `a l’échelle sur de grands volumes de données (BiTM-MR). Pour ce faire il est également basé sur la plateforme des technologies Big data. Mais il apporte davantage d’informations que notre algorithme SOM-MR car en plus de produire des groupes d’observations il associe des variables à ces groupes, formant ainsi des bi-groupes d’observations et variables.

In recent years, the amount of data analysed by companies and research laboratories increased strongly, opening the era of BigData. However, these raw data are frequently non-categorized and uneasy to use. This thesis aims to improve and ease the pre-treatment and comprehension of these big amount of data by using unsupervised machine learning algorithms.The first part of this thesis is dedicated to a state-of-the-art of clustering and biclustering algorithms and to an introduction to big data technologies. The first part introduces the conception of clustering Self-Organizing Map algorithm [Kohonen,2001] in big data…

▼ Tämän diplomityön tavoitteena on tutkia logistiikan kehittämisen ja operatiivisen johtamisen tarpeita datamallinnukselle sekä erilaisille automatisoiduille raporteille. Tutkimus toteutetaan Sandvik Mining and Construction Oy:n logistiikkaan. Yrityksessä on jo aiemmin tutkittu logistiikan saldovirheiden syitä ja työn laatua. Tutkimuksissa on havaittu, että erilaisia poikkeamia on niin paljon, että kokonaisuuden ja todellisten ongelmien havaitseminen on koettu mahdottomaksi. Tässä tutkimuksessa pyritään löytämään ratkaisuja juuri edellä mainittuun ongelmaan datamallinnuksen ja automaattisten raporttien avulla. Tavoitteena on, että tutkimuksen päätyttyä Sandvik pystyisi havaitsemaan eteenkin saldovirheitä kattavammin, kuin myös työn laadussa ja sen tehokkuudessa. Tehokkuuden osalta logistiikassa halutaan keskittyä erityisesti työmäärän ennustamiseen ja resurssointiin. Saldovirheiden havaitseminen datamallinnuksen ja raportoinnin avulla on yksi keskeisistä tutkimuskysymyksistä. Tutkimuksen osatavoitteena on löytää myös ratkaisuja ja toimenpiteitä havaittuihin ongelmiin. Toisena osatavoitteena on siirtää Sandvikin nykyisestä raportointijärjestelmästä (Cognos) kaikki tiedot uuteen järjestelmään (Microsoft Power BI). Yrityksessä on päätetty siirtyä kokonaan Microsoftin Power BI-ympäristöön, joten muutoksen tekeminen ja läpivienti on välttämätöntä. Tutkimus halutaan toteuttaa siis kokonaisuudessaan Microsoftin Power BI:tä hyödyntäen. Samalla tutkitaan, onko vanhoissa Cognos-raporteissa päivitettävää. Koska Power BI – ympäristö on myös Sandvikille suhteellisen uusi, niin tämän seurauksena ympäristöön ei ole vielä luotu kattavia tietomalleja, vaan ERP-tietokannan dataa käytetään vain satunnaisten raporttien tarpeisiin. Tästä johtuen samaa dataa saatetaan kysellä tietokannasta useaan kertaan usealle eri raportille samaan aikaan, eikä Sandvikin käytössä ole myöskään yrityksen omaa tietovarastoa. Tämä kuormittaa ja hidastaa tietokantaa turhaan, mikä voisi laajemmassa käytössä aiheuttaa tietokannan merkittävää hidastumista. Tämän tutkimuksen toisena päätavoitteena on rakentaa kaikki raportit samoihin tietomalleihin perustuen, jotta tietokantaa käytettäisiin mahdollisimman tehokkaasti eri raporttien tarpeisiin. Toisin sanoen samasta datasta on tarkoitus koostaa mahdollisimman monta eri raporttia, rasittamatta tietokantaa uusilla SQL-kyselyillä. Yrityksessä on tiedossa, että tietojen mallintamiselle ja automaattisille raporteille on yhä enemmän tarvetta, mutta tutkimusta aloitettaessa tarpeita ei osattu nimetä tarkasti. Oletuksena on kuitenkin se, että yksi suurimmista ongelmista, joita tutkimuksessa on tarkoitus havaita, ovat logistiikan saldovirheet ja sitä kautta työn laadun poikkeamat. Toisin sanoen datan analysoinnilla pyritään tuomaan esiin näitä virheitä, joita ei ole aiemmin pystytty havaitsemaan. Tutkimuksen käytännössä jo päätyttyä ilmeni yllättävä tieto, että Sandvik on ulkoistanut logistiikan ja toiminnot on myyty Transval Oy:lle. Tämä kauppa ei vaikuttanut tutkimuksen sisältöön, rakennettuun tietomalliin…

Tämän opinnäytetyön toimeksiantajana toimi Tampereen kaupungin Tietohallinnon Konserniyksikkö. Tampereen kaupungilla on käytössä tietovarastointi- ja raportointijärjestelmänä SAP Business Warehouse. Kaupungilla on valittu ICT-palveluiden tarjoamaksi tiedon analysointivälineeksi Microsoft Power BI. Tampereen kaupungin edistämä digitalisaatio ja kokeileva pilotointimalli aiheuttavat haasteita nykyisille tietojärjestelmille ja toimintamalleille saada tuotettua data-aineistoja nykyisillä resursseilla. Opinnäytetyö oli luonteeltaan laadullinen tutkimus, ja lähestymistapana käytettiin tapaustutkimusta. Opinnäytetyön tarkoituksena oli selvittää, mitä tietovarastointitekniikoita on olemassa, Power BI:n käyttömahdollisuudet analysointityökaluna sekä analysoida, minkälainen nykyinen Tampereen kaupungin tietovarastointi- ja raportointiympäristö on teoriaan verrattuna. Tutkimustyön tavoitteena oli tietovarastoinnin ja raportoinnin toteutusratkaisujen kartoittaminen teoriaan perustuen, yleisesti käytettyjen ratkaisujen selvittäminen sekä analysointi, kuinka Tampereen kaupungin nykytilaa tulisi kehittää, jotta Power BI:tä voitaisiin hyödyntää paremmin sote-tiedon analysoinnissa. Työssä perehdyttiin aihetta käsittelevään kirjallisuuteen ja muuhun kirjalliseen materiaaliin, tehtiin sähköinen kysely Power BI:n käyttötavoista sekä kartoitettiin Tampereen kaupungin tietovarastointi- ja raportointiympäristön nykytila. Tiedonkeruumenetelminä käytettiin kirjallisuuskatsausta, kvantitatiivista tutkimuskyselyä, havainnointia, sisäiseen dokumentaatioon perehtymistä sekä omakohtaista työkokemusta. Tutkimus päätyi johtopäätökseen, että nykytilaa tulisi kehittää, jotta Microsoft Power BI:tä voitaisiin hyödyntää täysimääräisesti sote-tiedon analysoinnissa. Tutkimuksessa löytyi useita kehityskohteita Tampereen kaupungin kokonaisarkkitehtuurista. Tutkimuksessa tunnistettiin 15 kehittämiskohdetta, joiden avulla nykytilaa voisi kehittää.

▼ Ellipsometry is an optical technique used for studies of thin films and surfaces. The technique is based on measurement and analysis of the changes in the state of polarization that occur when polarized light is reflected on a sample surface. The multichannel Mueller matrix ellipsometer is a new system that is about to enter the commercial market. It can measure the full 4x4 Mueller matrix of a sample. The Laboratory of Applied Optics at the Department of Physics, Chemistry and Biology at Linköpings University has purchased one such multichannel Mueller matrix ellipsometer, called RC2, from J.A. Woollam Co., Inc. This project has the objective to investigate potentials and limitations of this new ellipsometer. This is done by comparing measurements carried out on RC2 with similar measurements made on a different, well known ellipsometer system, the VASE ellipsometer. A study of the theoretical background of ellipsometry has been made including a description of the Jones formalism of describing optical properties as well as the Stokes/ Mueller formalism. A short theoretical description of the RC2 principles, in order to better understand the new ellipsometer is also given. Measurements have been made on samples of varying complexity, including isotropic and anisotropic samples with in-plane anisotropy and out-of-plane anisotropy. On samples with no depolarization there should be no difference between the two ellipsometers. As can be seen in the experimental results there is some difference, but very little. Both for the isotropic samples, where Δ and ψ have been measured, and anisotropic, where the full Mueller matrix has been measured, we find a good match between VASE and RC2. When the samples are depolarizing, we expect to see a difference in the Mueller matrix. We do notice a significant difference in the measurements on tilted nanometer rods of TiO2, which has an advanced nano-structure in the upper layer. We can thus conclude that samples with depolarizing properties reveal this when measured with the new RC2 ellipsometer.

La première partie de la thèse réunit des résultats classiques sur l’espace de Hardy, les espaces modèles et l’espace de Bergman. Puis sur cette base, nous exposons des travaux relatifs aux opérateurs de Toeplitz, en particulier, nous présentons la description du spectre et du spectre essentiel de ces opérateurs sur l’espace de Hardy et de Bergman. La première partie de notre recherche tire son inspiration de deux faits établis pour un opérateur de Toeplitz T. Premièrement, sur l’espace de Hardy, la norme de T, la norme essentielle de T et la norme infinie du symbole de T sont égales. Nous étudions ce cas d’égalité sur l’espace de Bergman pour les opérateurs de Toeplitz à symbole quasihomogène et radial. Deuxièmement, sur l’espace de hardy, le spectre et le spectre essentiel sont fortement liés à l’image du symbole de T. Nous étudions le cas d’égalité entre le spectre et l’image essentielle du symbole pour les symboles quasihomogènes et radials. Pour répondre à ces deux questions, nous utilisons la transformée de Berezin, les coefficients de Mellin et la moyenne du symbole. La dernière partie de la thèse s’interesse au théorème de Szegö qui donne un lien entre les valeurs propres d’une suite de matrices de Toeplitz de taille n, et le symbole de cette suite de matrice. Nous donnons un résultat du même type sur l’espace de Bergman pour les symboles harmoniques sur le disque et continus sur le cercle. Enfin, nous étudions une généralisation de ce théorème en compressant l’opérateur de Toeplitz sur une suite d’espaces modèles de dimension finie.

This thesis deals with the spectral properties of the Toeplitz operators in relation to their associated symbol. In the first part, we give some classical results about Hardy space, model spaces and Bergman space. Afterwards, we expose some results about Toeplitz operator on the Hardy space. In particular, we discuss their spectrum and essential spectrum. Our work is inspired from two facts which have been proved on the Hardy space. First, considering a Toeplitz operator T, the norm, essential norm, spectral radius of T and the supremum of its symbol are equal. Secondly, on the Hardy space, spectrum, essential spectrum and essential range are strongly related. We answer the question of the equality between the norms, the spectral radius and the supremum of the symbol and between spectrum and essential range on the Bergman space. We look at these two properties on the Bergman space when the symbol is radial or quasihomogeneous. We answer these questions using the Berezin transform, the Mellin coefficients and the mean value of the symbol. The last part deals with the classical Szegö theorem which underline a link between the eigenvalues of a Toeplitz matrix sequence and its symbol. We give a result of the same type on Bergman space considering harmonic symbol wich have a continuous extension. We give a generalization, considering the sequence of the compressions of a Toeplitz operator on a sequence of model spaces.
