  2. 16. Four Essays on Building Conditional Correlation GARCH Models

    Author : Tomoaki Nakatani; Handelshögskolan i Stockholm; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of four research papers. The main focus is on building the multivariate Conditional Correlation (CC-) GARCH models. In particular, emphasis lies on considering an extension of CC-GARCH models that allow for interactions or causality in conditional variances. READ MORE

  4. 17. Quantum Hall Wave Functions on the Torus

    Author : Mikael Fremling; Hans Hansson; Nicolas Regnault; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fractional Quantum Hall Effect; teoretisk fysik; Theoretical Physics;

    Abstract : The fractional quantum Hall effect (FQHE), now entering it's fourth decade, continues to draw attention from the condensed matter community. New experiments in recent years are raising hopes that it will be possible to observe quasi-particles with non-abelian anyonic statistics. These particles could form the building blocks of a quantum computer. READ MORE

  5. 18. Combinatorics of stable polynomials and correlation inequalities

    Author : Madeleine Leander; Petter Brändén; Jörgen Backelin; Carla Savage; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; matematik;

    Abstract : This thesis contains five papers divided into two parts. In the first part, Papers I-IV, we study polynomials within the field of combinatorics. Here we study combinatorial properties as well as the zero distribution of the polynomials in question. The second part consists of Paper V, where we study correlating events in randomly oriented graphs. READ MORE

  6. 19. Fluorescence correlation spectroscopy, photophysical aspects and applications

    Author : Jerker Widengren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Fluorescence correlation spectroscopy (FCS) is a technique where dynamic processes on the molecular level are studied by the use of fluorescence. The molecules are excited within a focused stationary laser beam and the resulting fluorescence fluctuations are analyzed in the form of an autocorrelation function. READ MORE

  7. 20. Non-overlapping Germ-grain Models: Characteristics and Material Modelling

    Author : Jenny Andersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poisson process; Convex sets; Material fatigue; Voronoi tessellation; Germ-grain process; Pair-correlation function; Mark-correlation function; Short cracks; Volume fraction; Germ-grain process;

    Abstract : We consider three different non--overlapping germ--grain models, two of which are constructed in a similar fashion. These two models are generalisations of Mat\'ern's hard--core models. In both cases we start with a homogeneous Poisson process and use the points as centres of convex sets, grains, of the same shape. READ MORE
