  1. 1. Implementation of Dyson equation to accelerate convergence in RS-LMTO-ASA code

    University essay from Uppsala universitet/Materialteori

    Author : Elis Uebel; Viktor Frilén; [2024]
    Keywords : Density functional theory; Dyson equation;

    Abstract : First-principle calculations is a key ingredient for us to understand, improve and design new materials. Density functional theory (DFT) [1] has proven to be a very powerful tool and a number of different versions exist depending on the problem at hand. READ MORE

  3. 2. Vehicle dynamics modelling of electromagnetic suspensions for MAGLEV applications

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Léa Chatelais; [2024]
    Keywords : MAGLEV; Dynamics; Requirements; Suspension; Vehicle modeling; MATLAB; MAGLEV; Dynamisk; Fordran; Upphängning; Fordon modell; MATLAB;

    Abstract : MAGnetic LEVitation Guidance System (MAGLEV) technology was commercially introduced relatively recently in the guided transport field. It is based on removing the wheels and rails of classic railway systems and supporting and guiding the train with magnets and magnetic forces instead. READ MORE

  4. 3. SHADING ANALYSIS OF AGRIVOLTAIC SYSTEMS : The shading’s effect on lettuce and potato from elevated agrivoltaic system in Sweden

    University essay from Mälardalens högskola/Framtidens energi

    Author : Komail Farid; Ahmad Guleed; [2023]
    Keywords : photosynthetically active radiation; agrivoltaic system; elevated system; crop yield; agriculture; shade tolerance crop; shading factor; PVsyst;

    Abstract : The world is progressing towards a more sustainable society, where renewable energy sources, including solar energy, play a crucial role. This study aims to address the conflict between agriculture and energy production by exploring the installation of solar panels on farmland. READ MORE

  5. 4. A review of the Kaczmarz method

    University essay from Lunds universitet/Matematikcentrum; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Carl Lokrantz; [2023]
    Keywords : Kaczmarz method; Least squares; Image reconstruction; Iterative method; Linear system of equations; Projection; Numerical Linear Algebra; Block Kaczmarz; Greedy Kaczmarz; Randomized Kaczmarz; Mathematics and Statistics;

    Abstract : The Kaczmarz method is an iterative method for solving linear systems of equations. The Kaczmarz method has been around since it was developed by Kaczmarz 1937. The main idea behind the original Kaczmarz method is to orthogonally project the previous x_k onto the solution space given by a row of the system. READ MORE

  6. 5. Fracture simulation with a hyperelastic phase field model

    University essay from KTH/Hållfasthetslära

    Author : Adrien Fradet; [2023]
    Keywords : Fracture; Phase field modeling; Hyperelasticity; Brott; fasfält-methoden; hyperelasticite;

    Abstract : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.
