  1. 1. Creating a Dynamic Model of a Gas Turbine in the MVEM Framework Using an Ellipse Compressor Model

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Edvin Hansson; [2020]
    Nyckelord :Gas turbine; Modeling; control;

    Sammanfattning : The legislations on greenhouse gas emissions are getting tougher and tougher every year. This drives the demand for energy efficient gas turbines with as low emissions as possible. This poses the challenge to manufacturers of constructing gas turbines with lessened environmental impact, but with maintained performance. LÄS MER

  2. 2. Patterning of the neural tube: A 3D computational modelling approach

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Ariane Ernst; [2019]
    Nyckelord :gene regulatory networks; neural tube patterning; patterning of the neural tube; dopaminergic neurons; parkinson s disease; computational modelling; stem cell; GRN; Biology and Life Sciences; Physics and Astronomy;

    Sammanfattning : Neurodegenerative diseases such as Parkinson’s can be treated with stem-cell derived specialized neurons. In order to achieve precise directed neural differentiation in vitro we need to understand the gene regulatory mechanisms behind in vivo neural tube patterning. LÄS MER

  3. 3. Decay of solutions to the Klein-Gordon equation on some expanding cosmological spacetimes

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik

    Författare :Amol Sasane; [2019]
    Nyckelord :Klein-Gordon equation; general relativity; FLRW models; Schwarzschild-de Sitter; Reissner-Nordström-de Sitter; Physics and Astronomy;

    Sammanfattning : The decay of solutions to the Klein-Gordon equation is studied in two expanding cosmological spacetimes, namely (1) the de Sitter universe in flat Friedmann-Lemaitre-Robertson-Walker (FLRW) form, and (2) the cosmological region of the Reissner-Nordström-de Sitter (RNdS) model. Using energy methods, for initial data with finite higher order energies, bounds on the decay rates of the solution are obtained. LÄS MER

  4. 4. Charge transport in a Hubbard-Holstein junction: Preliminary results from a DFT approach.

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Eric Ceccarelli; [2019]
    Nyckelord :Density functional theory; DFT; Hubbard-Holstein; Hubbard-Holstein model; HH; Quantum transport; Physics and Astronomy;

    Sammanfattning : Many-body systems are extremely complicated to describe due to mutual interactions between the constituent particles. This is for example the case of systems with electron-electron (e-e) and electron-phonon (e-ph) interactions. LÄS MER

  5. 5. Infuence of the modelling of truss joints made of hollow tube sections in finite element models

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mattheüs Lucassen; [2019]
    Nyckelord :Truss joints; Circular Hollow Sections CHS ; Fatigue; Finite Element Modelling FEM ; Crane; Boom section; Local joint exibility LJF ; Stress concentration factors SCF ; Fackverksled; Cirkulära ihåliga proler; Utmattning; Finita Elementmetoden FEM ; Kran; Kranarmsektion; Lokal ledexibilitet; Spänningskoncentrationsfaktorer.;

    Sammanfattning : Several boom segments form the crane boom. These segments are often truss structures formed out of circular hollow sections, which are welded together forming the truss joints. A adequate modelling of these truss joints is very important for operational strength and life. LÄS MER
