  1. 1. Wood and moisture-induced strains in a large deformation setting in 3D

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Fredrik Ström; Anwar Obeido; [2022]
    Nyckelord :Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

    Sammanfattning : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. LÄS MER

  3. 2. Routing on Resource Allocation in Free Space Optical Network.

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Författare :Md Arifur Rahman; [2016]
    Nyckelord :;

    Sammanfattning : Free space optical Networks (FSO) provide benefits such as high speed, cost efficiency and licence-free high bandwidth. However, these networks are susceptible to different atmospheric conditions. LÄS MER

  4. 3. Parallelisation and Performance Analysis of a TreeSPH Code for Galaxy Simulations

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Maximilian Volkan Baloglu; [2014]
    Nyckelord :;

    Sammanfattning : In cosmological simulations, the Lagrangian method Smoothed Particle Hydrodynamics is often applied to cover gas dynamics and combined with tree algorithms for long-range potentials like the Barnes-Hut method to include self-gravity and derive the nearest neighbour lists efficiently. In this thesis, a so-called TreeSPH code is parallelized by using MPI and subsequently the performance is analysed. LÄS MER

  5. 4. Lagrangian decomposition of the Hadley Cells

    Magister-uppsats, Meteorologiska institutionen (MISU)

    Författare :Joakim Kjellsson; [2009]
    Nyckelord :Lagrangian decomposition; Hadley; TRACMASS; trajectory streamfunction;

    Sammanfattning : The Lagrangian trajectory code TRACMASS is extended to the atmosphere to examine the tropi- cal Hadley Cells using fields from the ERA-Interim reanalysis dataset. The analysis is made using both pressure, temperature and specific humidity as vertical coordinates. LÄS MER
