Ryan, Greg. "Where the game was played by decent chaps: The making of New Zealand cricket 1832-1914." Thesis, University of Canterbury. History, 1996. http://hdl.handle.net/10092/4691.
Full textAbstract:
This thesis examines aspects of the relationship between cricket and New Zealand society from 1840 to approximately 1914. It proceeds from the premise that cricket, as the most significant component of the English leisure revolution of the nineteenth century, was encouraged in New Zealand as an important means of replicating English social customs and ideals.
The first section of the thesis examines the development of cricket in the four main provincial centres and in Nelson prior to 1870. These chapters reveal clear links between different colonisation patterns and the quite distinct cricketing traditions which emerged in each centre. Particular emphasis is placed on the role of cricket within the ideals of "systematic colonisation" promoted by Edward Gibbon
Wakefield - and especially as they relate to the primacy of
Canterbury cricket within the New Zealand game.
Section " examines selected themes in the expansion
and formalisation of New Zealand cricket between 1870 and
1914. Above all it addresses the process by which the upper
echelon of New Zealand cricket became dominated by middleclass,
white-collar professionals. Implicit is an account of
the impediments to blue-collar participation and the conflicts
which emerged between the various class groups competing
for scarce cricketing resources. This section also identifies
bureaucratic, demographic and geographic obstacles which
inhibited the expansion and standard of New Zealand cricket -
and particularly its representative teams.
Section III is primarily concerned with international
contacts by New Zealand cricket teams. It stresses both the
close relationship between cricket and notions of imperial and
inter-colonial unity, and the implications for a sense of
colonial or national identity which arose from the consistent
failure of New Zealand teams against international opposition.
Ultimately, it can be concluded that although New Zealand
embraced Victorian cricket ideals more thoroughly than many
other parts of the British Empire, the standard and
significance of the game was retarded by factors intrinsic to
the social structure of New Zealand as a whole.

Full textAbstract:
This thesis discusses aspects of a novel solar concentrating photovoltaic / thermal (PV/T) collector that has been designed to produce both electricity and hot water. The motivation for the development of the Combined Heat and Power Solar (CHAPS) collector is twofold: in the short term, to produce photovoltaic power and solar hot water at a cost which is competitive with other renewable energy technologies, and in the longer term, at a cost which is lower than possible with current technologies. To the authors knowledge, the CHAPS collector is the first PV/T system using a reflective linear concentrator with a concentration ratio in the range 20-40x. The work contained in this thesis is a thorough study of all facets of the CHAPS collector, through a combination of theoretical and experimental investigation.
A theoretical discussion of the concept of energy value is presented, with the aim of developing methodologies that could be used in optimisation studies to compare the value of electrical and thermal energy. Three approaches are discussed; thermodynamic methods, using second law concepts of energy usefulness; economic valuation of the hot water and electricity through levelised energy costs; and environmental valuation, based on the greenhouse gas emissions associated with the generation of hot water and electricity. It is proposed that the value of electrical energy and thermal energy is best compared using a simple ratio.
Experimental measurement of the thermal and electrical efficiency of a CHAPS receiver was carried out for a range of operating temperatures and fluid flow rates. The effectiveness of internal fins incorporated to augment heat transfer was examined. The glass surface temperature was measured using an infrared camera, to assist in the calculation of thermal losses, and to help determine the extent of radiation absorbed in the cover materials. FEA analysis, using the software package Strand7, examines the conductive heat transfer within the receiver body to obtain a temperature profile under operating conditions.
Electrical efficiency is not only affected by temperature, but by non-uniformities in the radiation flux profile. Highly non-uniform illumination across the cells was found to reduce the efficiency by about 10% relative. The radiation flux profile longitudinal to the receivers was measured by a custom-built flux scanning device. The results show significant fluctuations in the flux profile and, at worst, the minimum flux intensity is as much as 27% lower than the median. A single cell with low flux intensity limits the current and performance of all cells in series, causing a significant drop in overall output. Therefore, a detailed understanding of the causes of flux non-uniformities is essential for the design of a single-axis tracking PV trough concentrator. Simulation of the flux profile was carried out using the ray tracing software Opticad, and good agreement was achieved between the simulated and measured results. The ray tracing allows the effect of the receiver supports, the gap between mirrors and the mirror shape imperfections to be examined individually.
A detailed analytical model simulating the CHAPS collector was developed in the TRNSYS simulation environment. The accuracy of the new component was tested against measured data, with acceptable results. A system model was created to demonstrate how sub components of the collector, such as the insulation thickness and the conductivity of the tape bonding the cells to the receiver, can be examined as part of a long term simulation.

Full textAbstract:
Very little scholarly work has been written about Cape Town during the Second World War. Indeed, very little has been written about South African society at all during this period. This study is an attempt to contribute towards scholarly discussion of the effects of war on South African society, and to try to understand the largely neglected effects of the War on those who took part in it. Much of this study focuses on the experiences of white Englishspeaking veterans. This is because the majority of soldiers fighting in the Second World War were from this particular population group, and also because it was this group that was about to lose commanding political influence upon its return to South Africa. A central theme of this study is the government's neglect of the returning soldiers, and their failure to live up to their promises. The change of government in 1948 was to ensure that the needs of the ex-volunteers were never fully addressed, and that the veterans would never occupy the central position in society which they thought was their right, having fought in a war which many members of the new government had opposed. The focus on Cape Town also ensures that this study remains separate from the many papers which have been written detailing the rise of Nationalism from the late 1930s until the 1948 election. Looking at the other side of the political spectrum - at the eventual losers - has important and interesting political and historical implications, and adds a new dimension to the political history of the period. The methodology used for this study is mainly oral - interviews were conducted with a small representative sample of veterans and have provided a basis for all secondary research. Using the testimony of veterans has proved a useful and original tool for examining the period in question. One further aim of the thesis is to provide an opportunity for the voices of the veterans to be recognised as an authoritative resource about the history of Cape Town during the War and in the immediate post-War period. The thesis is split into two parts to reflect the different nature of Cape Town society during and after the War. The early part deals with Cape Town during the War and the changes which were taking place there as a result of South African participation in the conflict. This section also examines the wartime experiences of the soldiers and assesses how these experiences helped to forge new identities and behaviour after the War. Part Two looks at the post-War period and the demobilisation process, examining how it treated and prejudiced the soldiers who were involved.

Remy, Guillaume. "Intégrabilité du chaos multiplicatif gaussien et théorie conforme des champs de Liouville." Thesis, Paris Sciences et Lettres (ComUE), 2018. http://www.theses.fr/2018PSLEE051/document.
Full textAbstract:
Cette thèse de doctorat porte sur l’étude de deux objets probabilistes, les mesures de chaos multiplicatif gaussien (GMC) et la théorie conforme des champs de Liouville (LCFT). Le GMC fut introduit par Kahane en 1985 et il s’agit aujourd’hui d’un objet extrêmement important en théorie des probabilités et en physique mathématique. Très récemment le GMC a été utilisé pour définir les fonctions de corrélation de la LCFT, une théorie qui est apparue pour la première fois en 1981 dans le célèbre article de Polyakov, “Quantum geometry of bosonic strings”. Grâce à ce lien établi entre GMC et LCFT, nous pouvons traduire les techniques de la théorie conforme des champs dans un langage probabiliste pour effectuer des calculs exacts sur les mesures de GMC. Ceci est précisément ce que nous développerons pour le GMC sur le cercle unité. Nous écrirons les équations BPZ qui fournissent des relations non triviales sur le GMC. Le résultat final est la densité de probabilité pour la masse totale de la mesure de GMC sur cercle unité ce qui résout une conjecture établie par Fyodorov et Bouchaud en 2008. Par ailleurs, il s'avère que des techniques similaires permettent également de traiter un autre cas, celui du GMC sur le segment unité, et nous obtiendrons de même des formules qui avaient été conjecturées indépendamment par Ostrovsky et par Fyodorov, Le Doussal, et Rosso en 2009. La dernière partie de cette thèse consiste en la construction de la LCFT sur un domaine possédant la topologie d’une couronne. Nous suivrons les méthodes introduites par David- Kupiainen-Rhodes-Vargas même si de nouvelles techniques seront requises car la couronne possède deux bords et un espace des modules non trivial. Nous donnerons également des preuves plus concises de certains résultats connusThroughout this PhD thesis we will study two probabilistic objects, Gaussian multiplicative chaos (GMC) measures and Liouville conformal field theory (LCFT). GMC measures were first introduced by Kahane in 1985 and have grown into an extremely important field of probability theory and mathematical physics. Very recently GMC has been used to give a probabilistic definition of the correlation functions of LCFT, a theory that first appeared in Polyakov’s 1981 seminal work, “Quantum geometry of bosonic strings”. Once the connection between GMC and LCFT is established, one can hope to translate the techniques of conformal field theory in a probabilistic framework to perform exact computations on the GMC measures. This is precisely what we develop for GMC on the unit circle. We write down the BPZ equations which lead to non-trivial relations on the GMC. Our final result is an exact probability density for the total mass of the GMC measure on the unit circle. This proves a conjecture of Fyodorov and Bouchaud stated in 2008. Furthermore, it turns out that the same techniques also work on a more difficult model, the GMC on the unit interval, and thus we also prove conjectures put forward independently by Ostrovsky and by Fyodorov, Le Doussal, and Rosso in 2009. The last part of this thesis deals with the construction of LCFT on a domain with the topology of an annulus. We follow the techniques introduced by David-Kupiainen- Rhodes-Vargas although novel ingredients are required as the annulus possesses two boundaries and a non-trivial moduli space. We also provide more direct proofs of known results

Full textAbstract:
Cette these est constituee de trois parties s'articulant principalement autour d'un meme theme: l'etude des proprietes spectrales de certains operateurs couples a un champ de juage abelien. Celles-ci jouent un role dans la physique des systemes chaotiques et aussi dans l'etude des proprietes des chemins browniens. La premiere partie est consacree a une etude de certains developpements asymptotiques dans la limite semi-classique. Ceux-ci sont appliques au calcul du noyau de la chaleur en temps petit pour un probleme de billard quantique. Un argument tauberien permet alors de remonter a la densite d'etats integree a haute energie. Des corrections de bords sur le diamagnetisme de landau d'un gaz d'electrons libre sont discutees. La seconde partie montre la stabilite structurelle du chaos quantique, pour une certaine perturbation magnetique, dans un probleme de diffusion sur une surface a courbure negative constante. Ce type de systeme est celebre pour la grande stochasticite dont il fait preuve au niveau classique. La diffusion quantique exactement soluble fait apparaitre un dephasage reliee a la fonction dzeta de riemann. La troisieme partie contient des resultats concernants certaines proprietes statistiques d'aires balayees et d'enroulements de chemins browniens sur une surface riemannienne lisse. Ces extensions du cas planaire, deja connu, sont obtenus par l'utilisation d'integrales de chemins munies de contraintes topologiques covariantes. Des expressions fermees sont explicitement donnees dans le cas d'une marche brownienne sur une sphere

Full textAbstract:
La reconstruction globale de champ de vecteurs est une technique de modélisation phénoménologique de systèmes dynamiques déterministes à faible nombre de degrés de liberté. La méthode de reconstruction globale présentée dans ce manuscrit consiste à construire un système d'équations différentielles ordinaires à partir de la connaissance de l'évolution d'une observable au cours du temps. L'intégration du modèle ainsi obtenu fournit alors une reproduction du comportement dynamique de la variable observée. Cette technique et les améliorations qui lui ont été apportées au cours de ce travail y sont décrites, ainsi que les outils numériques mis au point afin de la rendre applicable à la plus vaste gamme de signaux possibles issus de systèmes expérimentaux. Sont ensuite proposés des exemples d'applications, à des signaux issus, i) de systèmes théoriques : Lorenz, Rossler, Burke & Shaw, système hyperchaotique de Rossler et équations de Duffing, ii) de systèmes expérimentaux : deux réactions de Belousov-Zhabotinskii, deux réactions d'électrodissolution (du cuivre et du fer), des instabilités de fil chaud et de lentille thermique, et un écoulement turbulent dans une cuve de mélange. Enfin, une extension de la méthode permettant d'inclure au modèle une dépendance explicite à des paramètres de contrôle du système observé est proposée. Une fois la faisabilité de cette dernière démontrée sur le système de Rossler, l'application de cette technique de modélisation est réalisée à partir des évolutions temporelles du courant mesurées sur une expérience d'électrodissolution du cuivre pour différentes valeurs du potentiel aux électrodes.

The existing world is becoming more disrupted and is falling apart. For its resurrection and restoration, a new way of thinking is necessary. This new type of thinking is needed to be able to open up its mind and to think about the process of thinking itself; it must understand what is happening in other systems, where processes seem to be taking place by themselves without any other visible interference. First Chaos is the title for an intermedia installation which contains 90 black and white photographs, both digital and analogue, all of which were taken between the years 2008 and 2012. Together, the photographs create one coherent piece – a kind of sculpture. They can evoke a "still film" with a non-linear, cyclical storyline, whilst the images can simultaneously function individually, without any connection to other photographs.

Full textAbstract:
Due to the limited resources available, it is necessary to prioritise the conservation action for taxa most at risk of extinction. This study investigated the systematics, population genetics and life-history traits of the two least studied threatened native olive species (Notelaea ipsviciensis and N. lloydii) in Australia, to improve our knowledge of their conservation biology. The results obtained from the genome wide molecular, morphological and comparative life-history trait analysis between rare and common Notelaea spp. in southern Queensland revealed that the taxonomic status of these two species should be re-evaluated and conservation priorities should be revised accordingly.

Hurricane shelters have become the unknown point of last resort for many coastal communities. Harboring displaced populations during a hurricane and it's chaotic aftermath are no longer seen as a need in a coastal communities evacuation strategy. The dangerous situation this strategy poses is being amplified by an increasing coastal population density along the Gulf Coast of the United States while the infrastructure to support mass scale evacuations is not growing in proportion to the population. Communities must face the realization that given the unpredictable nature of hurricanes, evacuation may not be possible for all citizens given the time frame before landfall. This thesis takes the role of harboring evacuees and wraps it into and around the program of a stadium. Being an icon of the city, the stadium will provide a foundation for inserting the hurricane shelter into the core fabric of coastal cities. Using the landscape and transportation infrastructure that feeds the stadium in its existing role, the shelter will engage the city as an icon to the memory of the threat, a point of protection from that threat and a point of aid following the threat.

Chaos Hill is a collection of short stories that represents the duality and paradox of existence in the lives of characters searching for a better place. The stories display man's connection to the physical world and his attempts to free himself from its cycles. The action of each story occurs within twenty-four hours and is concentrated on small changes and motion as resolution. In Chaos Hill, the world spins gravity into oppression, day and night roll relentlessly on, and only when dreams of escape die is the battle won.

Full textAbstract:
Cette habilitation porte sur une série d'expériences faites avec comme leitmotiv la condensation de Bose-Einstein à deux dimensions. Pour confiner très fortement les atomes dans une direction, nous avons utilisé deux approches différentes. Dans un premier temps, nous avons projeté d'utiliser deux champs évanescents, ce qui permet de réaliser des gradients de champ très importants. Avec cet objectif, nous avons produit un condensat et mis au point une méthode de transfert vers le piège à ondes évanescentes. La production d'un condensat à 3 mm seulement d'une surface a constitué une première. Nous avons réalisé une série d'expériences impliquant une seule onde évanescente, qui ont montré que la surface du diélectrique présentait une rugosité trop importante pour confiner efficacement les atomes en dimension 2. Cette étude nous a permis en revanche de caractériser très précisément l'interaction entre les atomes et le champ diffusé par les défauts de surface. Nos expériences ont confirmé quantitativement la théorie de Carsten Henkel et al., ce qui est un point important pour les expériences, de plus en plus nombreuses, menées à proximité directe d'une surface. Nous avons également montré que la diffraction était toujours clairement observable malgré la forte diffusion, lors du rebond d'un condensat sur un miroir modulé.Dans un second temps, sur la proposition d'Oliver Zobay et Barry Garraway, nous avons mis au point une nouvelle approche pour confiner les atomes dans des potentiels très anisotropes. La combinaison d'un champ radiofréquence (RF) et d'un champ magnétique statique résulte en un potentiel adiabatique dont la géométrie peut être largement contrôlée, y compris dynamiquement. Ces potentiels RF permettent de réaliser une « bulle » à atomes, un double puits, un anneau... Nous nous sommes intéressés principalement à produire un piège quasi bidimensionnel dans l'épaisseur de la bulle. Ces pièges sont compatibles avec les condensats de Bose-Einstein, et les atomes peuvent être refroidis par évaporation in situ. Nos premières expériences impliquant des champs radiofréquence ont eu un impact important dans la communauté des atomes froids, en particulier pour les expériences sur puce. A la suite de nos travaux, de nombreuses équipes ont utilisé cette technique avec succès.

This thesis is focused in the development of four different challenges, from passive chips (microparticles and barcodes) to biochemical and pressure sensors, as a proof of concept. All these prototypes present different shapes, sizes, and materials. Standard photolithographic and silicon-based technologies, which allow the obtaining of devices with lateral dimensions within the micro- and nanoscale to be internalized easily by the cell for single studies or ever by the study of each single cell in a population of cells. This work addresses specific objectives where the design, technological development, characterization and biological validation as intracellular chips inside living cells are described. The first demonstrators show dummy intracellular chips and intracellular barcodes for single cell labeling and tracking, as passive devices, where the design, technological development, characterization and biological validation are described. Technological capabilities of the definition of patterned chips are applied to obtain the intracellular barcodes code design. Furthermore, the chemical functionalization concept is applied to our intracellular devices, enabling a new line of applications for intracellular biochemical recognition. Finally, and going one step forward, and with the main objective of achieving even more functional intracellular chips, the design, technological development, characterization and validation of an intracellular pressure sensor inside a single cell is described. Being this device the first silicon-based NanoOptoMechanical System (NOMS) inside a living cell. Summarizing, the extensive capabilities of the presented intracellular silicon chips imply a broad number of applications in cell biology, such as cell labeling and tracking, and sophisticated intracellular cell sensing.

Full textAbstract:
I have always been fascinated by the marks in nature which arise from growth, fracture and decay, in fact by the overwhelming abundance of nature's complexity as described by Gleich (1990): Untamed, undomesticated, unregulated wildness. Nature paints its scenes without regard for conventional order, for straight lines or Euclidean shapes. Luckily so the human mind seems to take as little pleasure in a straight line as in pure formlessness. The essence of the Earth's beauty lies in disorder, a peculiarly patterned disorder, from the fierce tumult of rushing water to the tangled filigrees of unbridled vegetation. My early academic training was in mathematics. So later in life, when I began to study art, I compared the models for nature constructed by both mathematicians and artists, and became interested in the connections between geometry and art. Section 2 of this report describes my autobiographical context. On my BA and MA studies, I discovered that for most of the twentieth century phenomenological forms of nature were not a topic of artistic investigation, and geometry was being used in art as an abstract symbol of man's triumph over nature, via technology. But I also found that with the development of the electronic computer, scientists had advanced new models, such as chaos theory, to better describe nature's complex, dynamical, nonlinear systems. A new geometry, named fractal geometry, was formalised in the 1980s, which approached nature by finding patterns in its disorder. Traditional Euclidean geometry provides a poor approximation to natural disorder, but fractal geometry produces much more successful approximations. These fractal models of nature are likely to be chaotic but at the edges of the chaos an order can be found. I began to make abstract art using these new mathematical ideas, but not using digital computation or computer graphics. Section 3, on creative practice, follows my development through the five years I spent on the doctorate programme. I entered the course feeling that I had only scratched the surface of my visual enquiry into nature's structures based upon fractal geometry. I spent a year researching fractals in geometry and art in the context of the artists that influenced me, and put forward a proposal to devise a form of abstraction based upon 3

Jurczynski, Mateusz. "Quantum Wiener chaos." Thesis, Lancaster University, 2017. http://eprints.lancs.ac.uk/88760/.
Full textAbstract:
In this thesis we develop the theory of quantum Wiener integrals on the bosonic Fock space. We study multiple quantum Wiener integrals as an algebra of unbounded operators, investigating its properties, including closedness, common domains and multiplication formulas. We show the applications of the new formalism by providing new proofs to the established theory of quantum stochastic calculus and new conditions for generating quantum stochastic cocycles and quantum stochastic evolutions. The corresponding quasifree case is also studied and the constructions extended to fit in that formalism. We construct the multiple quantum Wiener integral as one operator on a family of operators which we dub operator kernels. This in particular covers the case of quantum stochastic cocycles and evolutions. We show that the family of quantum Wiener integrals forms a WOT-dense algebra of unbounded operators on the bosonic Fock space. We provide more general conditions for an operator kernel to be multiple quantum Wiener integrable, which allows us to treat multiple quantum Wiener integrals as an algebra. We explore the influence of an initial space on the theory. Our setting gives natural conditions for a product of two cocycles (evolutions) to still be a cocycle (an evolution). We apply our theory by solving quantum stochastic differential equations (QSDEs) and by finding more elementary proofs of structure conditions on the generator of a quantum stochastic evolution and of the fundamental estimate in the proof of quantum stochastic Lie–Trotter formula. We also show how our theory unifies and generalises the theory of integral kernels and chaotic representation properties, proving in particular that every Hilbert–Schmidt operator is a quantum Wiener integral.

Notre etude porte sur les recurrences modulaires (modulo un nombre entier), en liaison avec l'experimentation sur ordinateur - ce que l'on appelle les mathematiques experimentales. La discretisation forcee et les jeux cycliques imposes par l'ordinateur provoquent en effet deux effets contradictoires. D'une part, ils nous invitent a travailler modulo quatre dans le quadrillage des points de l'ecran. Nous en avons profite pour preciser comment tracer des courbes classiques ou fractales en etablissant un lien entre leur definition geometrique et leur definition linguistique. D'autre part, le passage d'un univers continu et infini dans un cadre discret et fini cree des phenomenes parasites, des interferences que l'on appelle le moire. Nous etudions ce phenomene d'entrelacement de courbes dans le cas d'un faisceau de droites et dans celui de cercles concentriques. Cela nous amene au theme essentiel de notre travail sur les recurrences modulaires : leur caractere periodique et l'organisation des trajectoires suivant un graphe oriente qui se decompose en composantes connexes formees de cycles et d'arborescences. Nous passons des progressions arithmetico-geometriques aux recurrences a base de matrices unimodulaires puis aux recurrences lineaires d'ordre deux, et enfin aux recurrences par elevation au carre. Nous nous interessons a la periode globale du phenomene, puis plus precisement aux periodes des cycles. C'est l'occasion d'observer la sensibilite aux conditions initiales, propre a la theorie du chaos, qui se manifeste des que l'on modifie un parametre, ou que l'on pratique des doubles melanges. La visualisation du graphe des trajectoires, pour des modulo donnes, presente souvent des elements de symetrie que nous expliquons. On aboutit ainsi a ce que nous appelons des portraits de nombres, ou se revelent leurs structures mathematiques sous-jacentes.

Ce texte etudie les champs de vecteurs quadratiques homogenes de c 3 qui sont uniformisables. Un champ est uniformisable si, grosso modo, ses solutions sont des fonctions univaluees (par opposition a multivaluees) dans tout leur domaine de definition. On decrit geometriquement des riches exemples etudies par halphen a la fin du xixeme. On prouve que ces champs n'ont pas d'integrale premiere meromorphe. Dans une deuxieme partie, on associe a un champ quadratique homogene des nombres complexes decrivant les dynamiques aux voisinages de certaines orbites et on prouve que ces nombres sont entiers si le champ est uniformisable. Finalement, via la resolution d'un systeme d'equations diophantiennes, on donne un theoreme de classification.

Full textAbstract:
Par une approche algebrique de la limite semi-classique, nous etudions deux problemes de mecanique quantique moderne. Dans une premiere partie, nous nous interessons au comportement des electrons sur un reseau en champ magnetique. A deux dimensions et dans l'approximation des liaisons fortes, un tel systeme est decrit par le hamiltonien de harper. Les techniques algebriques permettent l'obtention d'un developpement systematique des niveaux de landau en fonction de la constante de planck effective, ici proportionnelle au champ magnetique. A l'aide d'une diagonalisation numerique exacte du hamiltonien, nous montrons la precision des developpements semi-classiques pour differents modeles de type harper. La deuxieme partie est consacree a l'etude de la localisation dynamique pour des systemes quantiques dependant du temps. Le modele de base est represente par une tige rigide tournant, sans frottements, autour d'un axe fixe. On applique, a intervalles reguliers, une force a ce rotateur. Un tel modele presente une transition vers le chaos pour certaines valeurs des parametres tandis que son analogue quantique conserve un mouvement stable. Par une analogie en termes de localisation d'anderson sur ce modele, constante de diffusion classique et longueur de localisation quantique sont liees par la formule de chirikov-izrailev-shepelyansky, faisant apparaitre la constante de planck effective du probleme, proportionnelle au rapport des frequences du rotateur quantique et de la force appliquee. Par les techniques algebriques, nous relions la longueur de localisation a la valeur moyenne dans le temps de l'energie cinetique du rotateur quantique

Full textAbstract:
Dans un premier temps, nous introduisons une classe de champs réels appelés champs de Lévy multifractionnaires au moyen d'une représentation harmonisable. Cette classe contient à la fois celle des champs de Lévy fractionnaires et le mouvement brownien multifractionnaire (MBM en abrégé). Elle fournit notamment des exemples de champs non gaussiens du second ordre ayant des propriétés semblables à celles du MBM. En particulier, les champs de Lévy multifractionnaires sont localement autosimilaires et leur exposant de Hölder ponctuel peut varier le long d'une trajectoire. Par ailleurs, leurs propriétés sont gouvernées par leur fonction multifractionnaire. Par suite, d'un point de vue statistique, un problème naturel est l'identification de cette fonction. Comme dans le cas du MBM, elle peut être identifiée au moyen des variations quadratiques localisées et généralisées. Dans la deuxième partie, nous nous sommes intéressés à la simulation de la partie non gaussienne d'un champ de Lévy multifractionnaire. La méthode proposée est basée sur une représentation en série de bruits généralisés. Cependant, dans certains cas, on approche aussi une partie du champ de Lévy multifractionnaire par un MBM. Enfin, la dernière partie introduit un champ $X_(H,\be)$ localement autosimilaire avec un comportement atypique en $0$. En effet, alors qu'en tout point $x\ne0$, le champ tangent à $X_(H,\be)$ est un mouvement brownien fractionnaire, en général en $x=0$ le champ tangent à $X_(H,\be)$ est de nature bien différente. De plus, le champ $X_(H,\be)$ satisfait une propriété d'autosimilarité à grandes échelles et son étude est ensuite complétée par celle de la régularité des trajectoires et de la dimension de Hausdorff de ses graphes.

Full textAbstract:
This thesis describes the development and implementation of fibre-coupled, micron-scale optical resonators for the detection and manipulation of neutral atoms. The resonators are intended for integration with atom chips. The latter are microfabricated devices which enable the cooling, trapping, gUiding and manipulation of atoms by means of optical, magnetic and electric fields. The fields are generated in part using micro-fabricated features on the surface of the chips. Optical cavities are among the most important tools in the study of the interactions between light and matter. They allow the observation of fundamental processes in quantum optics, based on the enhanced coupling of atomic transitions to light fields. Our resonators have mode volumes which are two orders of magnitude smaller than those used in typical cavity quantum electrodynamics experiments. Together with their high quality factors, this leads to large enhancement factors, rendering them ideal for the detection and manipulation of atoms on chips. They are scalable and directly fibre-coupled, both of which are qualities of interest for their implementation in quantum information-processing applications. In the thesis, the optical characteristics of the resonators are explained, as well as the basic principles of the interaction of atoms with their light field. The setup used for the test implementation of the devices is presented, together with early experimental results. These include the detection of atoms via their effect on the cavity reflection spectrum, and the detection of enhanced atomic fluorescence into the cavity mode. The thesis concludes with an outlook on further experimentation, possible improvements of the devices themselves, and a view on their integration with existing atom chip technology.

Full textAbstract:
We consider a problem from the field of biological fluid mechanics which considers the flow associated with the motion of a flagellum on a sessile micro-organism. Motivation is taken from the movement of fluid around a species of choanoflagellate, \(Salpingoeca\) \(Amphoridium\). Choanoflagellates are a class of organism in the phylum Protozoa. Because the length scales and velocities are very low, the flow is one dominated by viscous forces and the environment is characterised by a low Reynolds number. The flow caused by the flagellum is initially modelled via a point force. These microorganisms operate in more than one location and the motion they create is modelled in a qualitative sense by using two stokeslets (appropriate to Stokes' flow) whose orientation and position is varied with time. The sessile micro-organism resides above a boundary which is modelled, most generally, as an interface between two fluids possessing different properties. Efficiency of feeding currents generated by the flagellum motion is studied. The resulting dynamics are investigated using chaotic measures, which examine the stretching and consequent mixing of elements within the fluid. Different point force locations lead to various eddy structures such that their superposition results in chaotic advection. The model is developed to examine the flow of particles around a three-dimensional realisation of a micro-organism which involves a flagellum and a cell body attached to a substrate. Green's functions are used to satisfy a number of boundary conditions simultaneously. Particle paths of a tracer introduced into the fully three-dimensional model are investigated. Comparisons with experimental data illustrate good agreement between theoretical and experimental results. Further extensions to the model are suggested.

Full textAbstract:
The purpose of this study was to critically evaluate Tom Stoppard’s application of chaos theory and quantum science in ROSENCRANTZ AND GUILDENSTERN ARE DEAD, HAPGOOD and ARCADIA; and determine the extent to which Stoppard argues for the importance of human action and choice.
Through critical analysis this study examined how Stoppard applies the quantum aspects of: (1) indeterminacy to human epistemology in ROSENCRANTZ AND GUILDENSTERN ARE DEAD; (2) complementarity to human identity in HAPGOOD; and (3) recursive symmetry to human history in ARCADIA. It also examined how Stoppard excavates the complexities of human action, choice and identity through the lens of chaos theory and quantum science.
These findings demonstrated that Tom Stoppard is not merely juxtaposing quantum science and human interactions for the sake of drama; rather, by excavating the complexities of human action, choice and identity through the lens of chaos theory and quantum science, Stoppard demonstrates the fundamental connection between individuals and the post-Newtonian universe.

Full textAbstract:
Cette thèse porte sur deux sujets principaux: l'évaluation de la stabilité d'une horloge sur microcircuit utilisant des atomes piégés (Trapped Atom Clock on a Chip - TACC) et l'extension de cette technologie vers la réalisation d'un interféromètre atomique sur la même puce. Cette combinaison constitue la base pour la réalisation de capteurs inertiels intégrés pour la navigation. Des travaux antérieurs ont installé l'horloge et ont découvert, entre autres, des temps de cohérence très longs, qui permettent une interrogation Ramsey jusqu'à 5 s, une condition préalable pour le fonctionnement à grande stabilité. Je présente ici la première évaluation approfondie de la stabilité de l'horloge. Avec mon prédécesseur, nous avons démontré les fluctuations de fréquences relatives de 5.8 10-13 à 1 s intégrant jusqu'à 6 10-15 à 30000 s.La deuxième partie de cette thèse vise à étendre la polyvalence de notre puce atomique pour créer un interféromètre. J'ai étudié divers régimes d'interféromètres en utilisant des potentiels habillés par microondes. Le premier régime consiste à déplacer l'un des états d'horloge verticalement pendant une séquence d'horloge Ramsey. Ceci permet la mesure de gradients de potentiel en exploitant la différence de fréquences entre les deux états. Le second régime utilise des champs microondes pour générer un potentiel de double puits dans l'un des états d'horloge et un seul puits dans l'autre.À partir du seul puits, un pulse-π sur la transition d'horloge constitue la séparatrice de l'interféromètre et conduit une séparation spatiale tout en préservant le même état interne pour les deux bras de l'interféromètreThis thesis covers two main subjects: the evaluation of the stability of a Trapped Atom Clock on a Chip (TACC) and the expansion of this technology towards creating an atom interferometer on the same chip. The combination of a clock and an interferometer on the same chip constitutes the basis for the realization of atom-based integrated inertial navigation units. Previous work installed the clock operation and discovered, among others, very long coherence times, which allow Ramsey interrogations of up to 5 s, a prerequisite for high stability operation. I present the first thorough evaluation of the clock stability. Together with my predecessor we have demonstrated relative frequency fluctuations of 5.8 10-13 at 1 s integrating down to 6 10-15 at 30,000 s. The second part of this thesis aims to expand the versatility of our atom chip to create an atom interferometer. I have studied various interferometer schemes using microwave dressed potentials and implemented these to the set-up. The first scheme, following work by P. Treutlein et al., involves displacing one of the clock states vertically during a Ramsey clock sequence thereby allowing the measurement of potential gradients by exploiting the differential frequency shift accumulated between the two states. Ramsey fringes where recorded for different durations of the splitting, resulting in a clear signal of the wavepacket separation. The second scheme uses microwave dressing to generate a double well potential in one of the clock states and a single well in the other. Starting in the single well, a π-pulse on the clock transition constitutes the beam splitter and leads to a spatial separation for the same internal state
