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

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Filip Ekblom; [2023]
    Keywords : Spin chain; Ising model; Dimer; Lattice; Lattice gauge theory;

    Abstract : 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. READ MORE

  3. 2. Unionism and Income An analysis of the Right to work laws on wage dispersion in the United States

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Karl Palmgren; [2023]
    Keywords : Right-to-work; Right to work; wage dispersion; Difference in Difference; Business and Economics;

    Abstract : In this thesis, I investigate the effect of introducing Right-to-work laws on wages and the dispersion of wages in the United States, using a staggered Difference in Difference model pioneered by Callaway & Sant’Anna (2021) on wages and individual wage quantiles. Introducing Right-to-work laws appear to have a generally positive effect on wages and wage dispersion for all wages. READ MORE

  4. 3. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Soraya Hosseinvash Azari; [2023]
    Keywords : Physical Geography; Ecosystem Analysis; noise simulation; traffic; Nord2000 model; building façade types; roof configurations; geospatial data; 3CIM; SoundPLAN; acoustic properties; urban areas; 3D city model; Earth and Environmental Sciences;

    Abstract : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. READ MORE

  5. 4. Inverse Uncertainty Quantification for Sounding Rocket Dispersion

    University essay from KTH/Matematik (Avd.)

    Author : Tove Ågren; [2022]
    Keywords : Uncertainty quantification; Bayesian inference; Rocket dispersion; Neural networks; Markov Chain Monte Carlo.; Osäkerhetskvantifiering; Bayesiansk inferens; Raketspridning; Neurala nätverk; Markovkedje-Monte Carlo;

    Abstract : Sounding rocket impact points are subject to dispersion due to uncertainties in simulation model parameters and perturbations of the rocket trajectory during flight. Estimating the area of dispersion assumes that associated model uncertainties and magnitude of perturbations have already been inferred. READ MORE

  6. 5. Planes of satellite galaxies

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Jessica Laura Erika Kocher; [2022]
    Keywords : Physics and Astronomy;

    Abstract : 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. READ MORE
