  1. 1. Exploring electroweak symmetry breaking in the scale-invariant Two-Higgs-Doublet Model

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Erik Rustas; [2023]
    Keywords : Two-Higgs-Doublet Models; 2HDM; Scale-invariance; Baryogenesis; BSM; Baryon Asymmetry; Coleman-Weinberg Potential; Theoretical Particle Physics; Physics and Astronomy;

    Abstract : This thesis investigates the properties of a general scale-invariant Two-Higgs-Doublet Model and its phenomenological consequences with focus on the scalar sector. The concept suggests that introducing more CP-violation, both spontaneous and explicit, may make it possible to meet the Sakharov conditions and account for the Universe's baryon asymmetry.

  3. 2. Gribov ambiguities in non-Abelian gauge theories

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Fredrik Granström; [2021]
    Keywords : Physics and Astronomy;

    Abstract : This thesis investigates the quantization of field theories using the functional integral formalism. Gauge invariance necessitates a gauge-fixing procedure that chooses a unique field configuration from each gauge orbit. READ MORE

  4. 3. Cellular automata analysis of life as a complex physical system

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Simon Tropp; [2020]
    Keywords : Cellular Automata; Self-organized Criticality; Casual Entropy; Entropy Maximization; Causal Entropic Forces; Biological Systems; Life; Game of Life; Statistical Physics; Non-linear Models; Physics and Astronomy;

    Abstract : This thesis regards the study of cellular automata, with an outlook on biological systems. Cellular automata are non-linear discrete mathematical models that are based on simple rules defining the evolution of a cell, depending on its neighborhood. READ MORE

  5. 4. Pedestrian Detection Using Convolutional Neural Networks

    University essay from Linköpings universitet/Datorseende; Linköpings universitet/Tekniska fakulteten

    Author : David Molin; [2015]
    Keywords : Convolutional neural network; pedestrian detection; Caltech pedestrian dataset;

    Abstract : Pedestrian detection is an important field with applications in active safety systems for cars as well as autonomous driving. Since autonomous driving and active safety are becoming technically feasible now the interest for these applications has dramatically increased. READ MORE

  6. 5. Hysteresis and Avalanches

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Paul Jaeger; [2013]
    Keywords : ;

    Abstract : In this thesis crackling systems have been investigated. Applying an external force on these systems they respond with events of all sizes. The size distribution follows a power law of the form S¯ . Dierent types appear in nature like avalanches or earthquakes. READ MORE
