  1. 6. Investigating Tweet Propagation via Dynamical Models and Influencer Analysis

    University essay from Linköpings universitet/Reglerteknik

    Author : Joel Nilsson; [2022]
    Keywords : Social Media Analysis; Dynamical Models; Data Mining;

    Abstract : Social media consume an increasing portion of people’s daily lives and are important platforms in the realms of politics and marketing for reaching out to voters and consumers. Describing and predicting the behaviour of users on social media is thus of interest for companies and politicians, as well as researchers studying information diffusion and human behaviour.

  3. 7. Dynamics for the special class of quantum master equations

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Locatelli Pietro; [2022]
    Keywords : superoperators; density matrices; von Neumann entropy; camel-like entropy; steady states; open quantum systems; dynamical semigroups; decoherence free subspaces;

    Abstract : The paper is an analysis of a special class of the master equations such that the Dissipation superoperator is L(ρ) = [M, [M, ρ]], where M is an hermitian andunitary operator and ρ a density matrix. It mainly investigates the dynamics ofρ and its properties such as boundness of the operators of the master equation,the eigenvalues of these operators, the purity of the states, the steady states.

  4. 8. Analysis and modelling of grooming behaviour of mice

    University essay from KTH/Fysik

    Author : Wilhelm Sjöstedt; [2022]
    Keywords : Theoretical physics; Neuroscience; Embedded systems; Complex systems; Teoretisk fysik; Neurovetenskap; Inbyggda system; Komplexa system;

    Abstract : Mapping dynamical motion to neural brain activity is one of many challenges in the field of neuroscience. Further knowledge in this area could provide useful insights in fields such as medical treatment of brain disorders. READ MORE

  5. 9. General Relativity and Dynamical Universes

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Kajsa Fransson; [2021]
    Keywords : cosmology; general relativity; scale factor; friedmann equation;

    Abstract : The aim of this report is to explore different models of cosmology, depending on components as matter, radiation and dark energy. To be able to investigate the behaviour and age of these model universes, it is necessary to solve the Friedmann equation. READ MORE

  6. 10. Models of the Universe : An analysis of the asymptotic behaviour of non-linear dynamical systems

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Noa Vikman; Gustav Romare; [2021]
    Keywords : ;

    Abstract : In this thesis we present some relevant theory, and then we rigorously investigate the existence intervals and the asymptotic behaviors of three cosmological models. The first model we investigate is based on the Friedmann-Lemaître-Robertson-Walker (FLRW) metric, which is consistent with the cosmological principle. READ MORE
