  1. 1. Exploring time-extended complexity measures in magnetic systems

    L3-uppsats, Uppsala universitet/Materialteori

    Författare :Jannes van Poppelen; [2023]
    Nyckelord :;

    Sammanfattning : Complexity, a fundamental concept in physics, encompasses phenomena spanning atomic to cosmic scales. The natural emergence of complexity can be explained by self-organized criticality. In this work, two complexity measures in magnetic systems are explored. LÄS MER

  3. 2. Quantifying the Impact of Synaptic Delay and Neuronal Refractory Period on Criticality in Hierarchical Modular Neural Networks

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hannes Gustafsson; [2023]
    Nyckelord :;

    Sammanfattning : Self-organized brain criticality suggests that the brain is able to operate near a critical point.With compelling evidence supporting the theory, it is important to understand whichbiological mechanisms are required for critical dynamics to occur. LÄS MER

  4. 3. Study of Generalizations of the Discrete Bak-Sneppen Model

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Marina Panicheva; [2021]
    Nyckelord :Bak-Sneppen; Discrete Bak-Sneppen; co-evolution; self-organized criticality; Mathematics and Statistics;

    Sammanfattning : In 1993, Per Bak and Kim Sneppen proposed a model of co-evolution between species, where survival of a particular species affects the survival of its neighbouring species. In the discrete case of the model, each species, or an entry in a set with periodic boundary conditions, is an element x_i ∈ {0, 1}, in the set of size N, where x_i represents the fitness. LÄS MER

  5. 4. 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

  7. 5. Critical Branching Regulation of the E-I Net Spiking Neural Network Model

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Oskar Öberg; [2019]
    Nyckelord :Pattern recognition; Spiking neural network; Critical branching; Self-organized criticality; Spike-based learning; Brain-inspired computing; Signal processing;

    Sammanfattning : Spiking neural networks (SNN) are dynamic models of biological neurons, that communicates with event-based signals called spikes. SNN that reproduce observed properties of biological senses like vision are developed to better understand how such systems function, and to learn how more efficient sensor systems can be engineered.
