  2. 1. Search for Dark Matter and Extra Dimensions in Monojet Final States with the ATLAS Experiment

    Author : Olof Lundberg; Christophe Clement; Chad Finley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark Matter; LHC; ATLAS; Extra Dimension; Gravity; Calorimeter; High Energy Physics; högenergifysik;

    Abstract : The CERN Large Hadron Collider (LHC) is the most powerful particle ac- celerator ever built, in terms of luminosity and center-of-mass energy of the collisions. This thesis presents a search for Dark Matter and Extra Dimen- sions in the proton-proton collisions as recorded by the ATLAS detector. READ MORE

  4. 2. Spatial and Physical Splittings of Semilinear Parabolic Problems

    Author : Erik Henningsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; splitting schemes; parabolic equations; semilinear; evolution equations; dissipative; convergence order; dimension splitting; domain decomposition; axonal growth;

    Abstract : Splitting methods are widely used temporal approximation schemes for parabolic partial differential equations (PDEs). These schemes may be very efficient when a problem can be naturally decomposed into multiple parts. READ MORE

  5. 3. Mathematical Model of the Solid Flow Behavior in a Real Dimension Blast Furnace

    Author : Reza Safavi Nick; Pär Jönsson; Lage Jonsson; Anders Tilliander; Dong-Yuan Sheng; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : A mathematical model based on the continuum mechanic concept has been developed to describe the profile of solid particles in an industrial scale blast furnace. The focus is the in-furnace conditions and its characteristics such as the shape and size of the deadman. READ MORE

  6. 4. Extra- and intracellular electronic conductance of signals and its significance for synaptic plasticity

    Author : Isaac Shemer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Electrical signals play a pivotal role in the normal function of most if not all organisms. Understanding the electrophysiological principles that govern electrical signaling is essential for insights into normal- and pathological processes in cell biology. READ MORE

  7. 5. Phenomenological studies of dimensional deconstruction

    Author : Tomas Hällgren; Tommy Ohlsson; Stefan Antusch; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dimensional deconstruction; higher-dimensional gauge theories; neu- trino mixing; neutrino oscillations; universal extra dimensions; ADD models; Ka- luza{Klein dark matter; Other physics; Övrig fysik;

    Abstract : In this thesis, two applications of dimensional deconstruction are studied. The first application is a model for neutrino oscillations in the presence of a large decon- structed extra dimension. In the second application, Kaluza{Klein dark matter from a latticized universal extra dimension is studied. The goal of these projects have been twofold. READ MORE
