  1. 11. Fractal Methods for Greyscale Image Data Compression

    Författare :Mirek Novak; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis fractal methods for image coding of still images are discussed. A specific class of encoding algorithms is introduced, where the algorithms are based on dividing image data into two components. One component is the part of the data which can be represented by a parametric model. LÄS MER

  4. 13. Combinatorial and analytical problems for fractals and their graph approximations

    Författare :Konstantinos Tsougkas; Anders Karlsson; Anders Öberg; Ben Hambly; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fractal graphs; energy Laplacian; Kusuoka measure; Mathematics; Matematik;

    Sammanfattning : The recent field of analysis on fractals has been studied under a probabilistic and analytic point of view. In this present work, we will focus on the analytic part developed by Kigami. The fractals we will be studying are finitely ramified self-similar sets, with emphasis on the post-critically finite ones. LÄS MER

  5. 14. Geometrical and percolative properties of spatially correlated models

    Författare :Olof Elias; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; continuum percolation; brownian excursions; brownian interlacements; poisson cylinder model; fractal percolation;

    Sammanfattning : This thesis consists of four papers dealing with phase transitions in various models of continuum percolation. These models exhibit complicated dependencies and are generated by different Poisson processes. For each such process there is a parameter, known as the intensity, governing its behavior. LÄS MER

  7. 15. Fractal superconducting resonators for the interrogation of two-level systems

    Författare :Sebastian Erik de Graaf; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cooper-pair box; decoherence; electron spin resonance; two-level systems; atomic force microscopy; quasiparticles; near-field scanning microwave microscopy; Superconducting resonators; circuit quantum electrodynamics;

    Sammanfattning : In this thesis we use high-Q superconducting thin-film microwave resonators to interact with several types of quantum mechanical two-level systems. Such a resonator is used as the central building block in a cryogenic near-field scanning microwave microscope (NSMM) to reach a completely new regime of NSMM operation. LÄS MER
