Exploring random geometry with the Gaussian free fieldJackson, Henry Richard January 2016 (has links)
This thesis studies the geometry of objects from 2-dimensional statistical physics in the continuum. Chapter 1 is an introduction to Schramm-Loewner evolutions (SLE). SLEs are the canonical family of non-self-intersecting, conformally invariant random curves with a domain-Markov property. The family is indexed by a parameter, usually denoted by κ, which controls the regularity of the curve. We give the definition of the SLEκ process, and summarise the proofs of some of its properties. We give particular attention to the Rohde-Schramm theorem which, in broad terms, tells us that an SLEκ is a curve. In Chapter 2 we introduce the Gaussian free field (GFF), a conformally invariant random surface with a domain-Markov property. We explain how to couple the GFF and an SLEκ process, in particular how a GFF can be unzipped along a reverse SLEκ to produce another GFF. We also look at how the GFF is used to define Liouville quantum gravity (LQG) surfaces, and how thick points of the GFF relate to the quantum gravity measure. Chapter 3 introduces a diffusion on LQG surfaces, the Liouville Brownian motion (LBM). The main goal of the chapter is to complete an estimate given by N. Berestycki, which gives an upper bound for the Hausdor dimension of times that a γ-LBM spends in α-thick points for γ, α ∈ [0, 2). We prove the corresponding, tight, lower bound. In Chapter 4 we give a new proof of the Rohde-Schramm theorem (which tells us that an SLEκ is a curve), which is valid for all values of κ except κ = 8. Our proof uses the coupling of the reverse SLEκ with the free boundary GFF to bound the derivative of the inverse of the Loewner flow close to the origin. Our knowledge of the structure of the GFF lets us find bounds which are tight enough to ensure continuity of the SLEκ trace.

Dánské divadlo a drama v 90. letech 20. století / Danish Theatre and Drama in the 1990sŠvehlová, Táňa January 2012 (has links)
DANISH THEATRE AND DRAMA IN 1990'S TÁŇA ŠVEHLOVÁ Abstract: The thesis deals with the blom of Danish drama in the 1990s. The first chapter Theatre Context concerns the cultural-political grounds for the development of new writing for theatre, and introduces the most significant theatres that to stage Danish drama. The second chapter Dramatics in the 1990's is a literary-historical approach to 9 of the most important playwrights' work (N.Cederholm, E. Jepsen, J. Ørnsbo, A. Saalbach, J. Rohde, M. Vizki, P. Asmussen, N. Werdelin, L. Knutzon). The final chapter presents a practical insight into Danish drama via an anylysis of Line Kunzon's drama Soon the Time Will Come (Snart kommer tiden, 1998).

Design and implementation of a 5GHz radio front-end moduleBackström, Anders, Ågesjö, Mats January 2004 (has links)
<p>The overall goal of this diploma work is to produce a design of a 5 GHz radio frontend using Agilent Advanced Design System (ADS) and then build a working prototype. Using this prototype to determine if RF circuits at 5 GHz can be successfully produced using distributed components on a laminate substrate. </p><p>The design process for the radio front-end consists of two stages. In the first stage the distributed components are designed and simulated, and in the second stage all components are merged into a PCB. This PCB is then manufactured and assembled. All measurements on the radio front-end and the test components are made using a network analyser, in order to measure the S-parameters. </p><p>This diploma work has resulted in a functional design and prototype, which has proved that designing systems for 5 GHz on a laminate substrate is possible but by no means trivial.</p>
