  1. 1. Regional Inequality and Spatial Dependence in Sweden

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Samuel Malmström Arfwedson; [2023]
    Nyckelord :Regional inequality; convergence; spatial dependence; spatial econometrics; Sweden; Business and Economics;

    Sammanfattning : Regional inequality is a growing concern in developed countries, as country-level convergence may obscure increasing disparities within countries. This thesis aims to address this concern by examining the dynamics of regional convergence in Sweden from 1980-2022. LÄS MER

  3. 2. Z2-Gauge Theory with Matter : Dispersive behaviour of a dimer in a 1+1-dimensional lattice

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Filip Ekblom; [2023]
    Nyckelord :Spin chain; Ising model; Dimer; Lattice; Lattice gauge theory;

    Sammanfattning : The intention with this thesis is to investigate a dimer in a spin chain. Inorder to do that, a model from Z2-gauge theory is taken as the theoretical motivation to construct a discrete lattice with Ising spin properties. A dimer is then allowed to exist indirectly in the empty space between sites. LÄS MER

  4. 3. Planes of satellite galaxies

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Jessica Laura Erika Kocher; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The Planes of Satellites Problem is an open question within the field of galaxy formation. It is based on the observations that the Milky Way's satellites, as well as those around the Andromeda (M31) galaxy, align in planes. LÄS MER

  5. 4. Implementing spatial variance in the rate of photolytic breakdown of NO2 in urban street canyons

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fabian Friberg; [2022]
    Nyckelord :cfd; computational fluid dynamics; NOx; street canyon; NO2; NO; O3; photolysis; OpenFOAM; Physics and Astronomy;

    Sammanfattning : In this study a module for calculating the solar exposure of individual fluid cells was developed to more accurately represent the effect of photolysis on the pollutant dispersion in an urban street canyon. The module was tested and validated on 12 different cases, each with a different geographical location, time of year and/or time of day. LÄS MER

  7. 5. Simulation Testbed for Liquid Chromatography

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :David Andersson; [2021]
    Nyckelord :;

    Sammanfattning : The stlc package is proposed as a tool for simulation of liquid chromatography by implementing several lumped kinetic models which combine diffusive mass  transport and adsorption isotherm equations. The purpose of the package is to provide computationally efficient approximations to the general rate model of chromatography. LÄS MER
