  1. 1. Vibrations in a high frequency clt floor panel - Measurement, prediction and evaluation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :André Wirthig; [2023]
    Nyckelord :Vibrations; High frequency floors; Sensitive equipment; Technology and Engineering;

    Sammanfattning : There is an increased need for floors that can accommodate different type of sensitive equipment [1]. Further, it is recommended to design these floors as high frequency floors (HFF) to be able to meet the stringent vibration criteria [1]. LÄS MER

  3. 2. Diffusion and Camera-Noise Modelling for Analysis of Single-Particle Tracking Movies

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Erik Clarkson; [2022]
    Nyckelord :reaction-diffusion; camera-noise modelling; single-particle tracking; Gillespie simulations; Physics and Astronomy;

    Sammanfattning : Interactions between T-cells and other body cells is an essential part of the immune system. It involves the binding between surface receptors of the two cells. Specifically, T-cell receptors (TCRs) bind onto pMHC (peptide-loaded major histocompatibility complex) molecules on the partnering cell surface. LÄS MER

  4. 3. Studying Atomic Vibrations by Transmission Electron Microscopy

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Sebastian Cardoch; [2016]
    Nyckelord :graphene; lammps; molecular dynamic simulations; phonon dispersion; airebo; empirical potential function; carbon isotopes; vibrations; vibrational properties; tem; transmission electron microscopy; msd; mean square displacement; phonons;

    Sammanfattning : We employ the empirical potential function Airebo to computationally model free-standing Carbon-12 graphene in a classical setting. Our objective is to measure the mean square displacement (MSD) of atoms in the system for different average temperatures and Carbon-13 isotope concentrations. LÄS MER

  5. 4. Diffusion in the liquid Co binder of cemented carbides: Ab initio molecular dynamics and DICTRA simulations

    Master-uppsats, KTH/Materialvetenskap

    Författare :Martin Walbrühl; [2014]
    Nyckelord :Ab initio; molecular dynamics; AIMD; DICTRA; cemented carbides; hardmetals; diffusion; liquid Co; cobalt; binder phase;

    Sammanfattning : A fundamental quantum mechanical modelling approach is used for calculating liquid diffusion parameters in cemented carbides. Up to now, no detailed description of diffusion for alloying elements in a liquid Co matrix is available. LÄS MER

  7. 5. Tracer Particle Dynamics in Heterogeneous Many-body Systems

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Karl Fogelmark; [2010]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : By use of a lattice random walk algorithm we model diffusion in a many-body system and study the mean square displacement (MSD) for a tagged particle for different distributions of crowding particles, with particular emphasis on obtaining the correlation factor which contains the corrections to the mean-field result in such a system. The MSD in such a crowded environment is investigated and we find that the analytical correlation factor developed by Nakazato et al. LÄS MER
