  2. 16. Properties of heavy rainfall in an East Asian monsoon catchment - Analysis of daily rain gauge data

    Author : Cecilia Svensson; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China.; Huai River; East Asian monsoon; typhoon; Mei-Yu front; fractals; empirical orthogonal function analysis; correlation analysis; probable maximum precipitation; storm movement; seasonal occurrence; Rainfall; spatial pattern; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 18. On two-dimensional conformal geometry related to the Schramm-Loewner evolution

    Author : Lukas Schoug; Fredrik Viklund; Nathanaël Berestycki; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Conformal invariance; scaling; random fractals; Mathematics; Matematik;

    Abstract : This thesis contains three papers, one introductory chapter and one chapter with overviews of the papers and some additional results. The topic of this thesis is the geometry of models related to the Schramm-Loewner evolution.In Paper I, we derive a multifractal boundary spectrum for SLEκ(ρ) processes with κ.. READ MORE

  6. 19. Fixed points, fractals, iterated function systems and generalized support vector machines

    Author : Xiaomin Qi; Sergei Silvestrov; Anatoliy Malyarenko; Daniel Andren; Viktor Abramov; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; support vector machine; fixed points; iterated function system; variational inequality; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : In this thesis, fixed point theory is used to construct a fractal type sets and to solve data classification problem. Fixed point method, which is a beautiful mixture of analysis, topology, and geometry has been revealed as a very powerful and important tool in the study of nonlinear phenomena. READ MORE

  7. 20. Reappraisal of market efficiency tests arising from nonlinear dependence, fractals, and dynamical systems theory

    Author : Gun-Ho Cha; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : The efficient market hypothesis (EMH) has long been perceived as the cornerstone of modern finance theory. However, the EMH has also recently been dismissed as "the most remarkable error in the history of economic theory" (Wall Street Journal, Oct. 23. 1987). READ MORE
