  1. 1. Strukturella förbättringar av en markstabiliseringsmast

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Axel Skog; [2021]
    Nyckelord :ANSYS; FEA; SpaceClaim; SolidWorks; Jet-Grouting; Camatec; Scandinavian Pile Driving; ground stabilization; CAE; CAD; ANSYS; FEM; SpaceClaim; SolidWorks; Jet-Grouting; Camatec; Scandinavian Pile Driving; markstabilisering; CAE; CAD;

    Sammanfattning : This report has examined the possibilities of stiffening and strengthening a ground stabilization mast, in a way that a small production company can manufacture. The soil stabilization technique in question is Jet-Grouting also called injection drilling, which involves drilling to the desired depth and then letting high-pressure water jets mixed with filling mass to erode the surrounding soil mass and form pillars below the ground surface.

  2. 2. Modelling and Simulation of Hydrogen Diffusion in High Strength Steel

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Vikas Vineeth Seru; Venkata Ramana Murthy Polinati; [2021]
    Nyckelord :Coupled temperature displacement; finite element software; high strength steel; hydrogen diffusion; material properties.;

    Sammanfattning : This research is about modelling and simulation of how the hydrogen diffuses in high strength steels. The hydrogen diffusion in the material was examined by using finite element software with the help of material properties and some existing data. LÄS MER

  3. 3. Squaring VEGAS -- Multidimensional Integration Using 2D Correlations

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik

    Författare :Philip Siemund; [2021]
    Nyckelord :statistics; numerical integration; Monte Carlo integration; VEGAS; Physics and Astronomy;

    Sammanfattning : Multidimensional integrals are used in many areas of physics; electrodynamics, quantum mechanics and statistical physics, to name a few. Many integrals can not be solved analytically, but can instead be approximated numerically. VEGAS is a Monte Carlo integration algorithm, which specializes it in approximating multidimensional integrals. LÄS MER

  4. 4. Variations in material properties of grey cast iron and its impact on tool wear

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell Produktion

    Författare :Andreas Söderholm; [2021]
    Nyckelord :Grey cast iron; hard inclusions; tool wear; machinability; graphite structure.; Technology and Engineering;

    Sammanfattning : Among cast materials, grey cast iron and ductile iron makes up about three quarters of all cast parts. This makes the manufacturing and machining of grey cast iron an important economical factor for the automotive industry. LÄS MER

  5. 5. On Levi Decompositions in Finite and Infinite Dimensional Lie Algebras

    Kandidat-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Hannes Nilsson; [2021]
    Nyckelord :Lie algebra; Levi s theorem; Cohomology; Virasoro algebra; Mathematics and Statistics;

    Sammanfattning : In this bachelor thesis we introduce Lie algebras, and use Lie algebra cohomology to prove Levi's theorem about splitting of finite dimensional Lie algebras. We then construct the Virasoro algebra, compute its low dimensional cohomology spaces, and use this to demonstrate why Levi's theorem does not hold in the infinite dimensional case... LÄS MER
