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

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Simon Tropp; [2020]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Pedestrian Detection Using Convolutional Neural Networks

    Master-uppsats, Linköpings universitet/Datorseende; Linköpings universitet/Tekniska fakulteten

    Författare :David Molin; [2015]
    Nyckelord :Convolutional neural network; pedestrian detection; Caltech pedestrian dataset;

    Sammanfattning : 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. LÄS MER

  5. 4. Hysteresis and Avalanches

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Paul Jaeger; [2013]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  7. 5. A Hardware Architecture for Scale-space Extrema Detection

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Hamza Ijaz; [2012]
    Nyckelord :SIFT; computer vision; scale invariance; scale-space extrema detection; FPGA; feature detection; gaussian smoothing; separable;

    Sammanfattning : Vision based object recognition and localization have been studied widely in recent years. Often the initial step in such tasks is detection of interest points from a grey-level image. LÄS MER
