  2. 1. Cluster investigations of the extent and altitude distribution of the auroral density cavity

    Author : Love Alm; Göran T. Marklund; Tomas Karlsson; Rickard Lundin; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Auroral density cavity; auroral accelaration; Cluster; in situ observation; electron density; pseudo altitude; Physics; Fysik;

    Abstract : The auroral density cavity constitutes the boundary between the cold, dense ionospheric plasma and the hot, tenuous plasma sheet plasma. The auroral density cavity is characterized by low electron density and particle populations modified by parallel electric fields. READ MORE

  4. 2. Cluster Effective Field Theory

    Author : EMIL RYBERG; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; effective field theory; charge radius; resonant state; renormalization; radiative capture; halo nuclei; power counting; nuclear physics; few-body physics;

    Abstract : Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as an effective degree-of-freedom without internal structure. READ MORE

  5. 3. Electrical Properties of Carbon Black Polymer Composites: Filler Particle Rearrangement

    Author : Karl Michael Jäger; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conductivity; fractal; permittivity; carbon black; dielectric; electron tunnelling; polymer; image analysis; cluster; percolation;

    Abstract : The practical application of semi-conducting carbon black polymer composites often involves temperature variations resulting in changes in their electrical properties. Study of cross-linked ethylene butylacrylate copolymer (EBA) filled with acetylene black has shown that these changes are due to carbon black network re-arrangement. READ MORE

  6. 4. Theoretical Reflections of Solvation in Polar Media

    Author : Daniel Hagberg; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kvantkemi; Teoretisk kemi; quantum chemistry; Theoretical chemistry; Coordination; Water; Uranyl; Intermolecular forces; Simulation; Dielectric; Cluster; Hofmeister series; Ion; Interaction; Dipole;

    Abstract : Using experiments it is rather easy to measure things on the macroscopic length scale, while it is much harder to measure something in the microscopic world like molecular structure. The opposite is true in theoretical chemistry. READ MORE

  7. 5. Feasible computation of generalized linear mixed models with application to credit risk modelling

    Author : Md. Moudud Alam; Göran Boström; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Credit risk; cluster correlation; GLMM; large data; two-step pseudo likelihood estimation; defaults contagion; predictive likelihood; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Statistics; Statistik; Statistics; Statistik; Complex Systems – Microdata Analysis;

    Abstract : This thesis deals with developing and testing feasible computational procedures to facilitate the estimation of and carry out the prediction with the generalized linear mixed model (GLMM) with a scope of applying them to large data sets. The work of this thesis is motivated from an issue arising incredit risk modelling. READ MORE
