  1. 6. On the Energy Dependence of Parameters in PYTHIA8 Heavy-ion Collision Simulations

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Felipe Abedrapo; [2022]
    Keywords : Heavy-ion Collisions; PYTHIA; Angantyr; Physics and Astronomy;

    Abstract : Particle collisions are an essential component to the research methodology of particle physics. These investigations are not only conducted in experimental laboratories but also through programs such as PYTHIA that simulate a collision or ``event" and then compare its results to known experimental data.

  3. 7. Feasibility Study of Wind Turbine Blades Constructed in 1300 MPa Fossil-Free Steel : Finite Element weight optimization with respect to structural integrity by Abaqus and Tosca Structure

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Peter van der Brug; Sina Urban; [2022]
    Keywords : Abaqus; Tosca Structure; Wind Turbine Blade; Weight Optimization; High-Strength Steel; Fossil-Free; SSAB; Strenx 1300; DTU 10MW-RWT;

    Abstract : This study aims to perform a feasibility study on the DTU 10MW-RWT wind turbine blades constructed in the fossil-free high-strength steel 1300 MPa from SSAB. The acceptance criteria, on which the study is based, are taken from the DTU composite wind turbine model. A maximum weight of 41 000kg and a maximum tip displacement of 12.5 m are chosen. READ MORE

  4. 8. Electrodynamic field at spatial infinity

    University essay from KTH/Fysik

    Author : Jakob Myhrman; [2022]
    Keywords : Spatial infinity; Conformal rescaling; Minkowski space; Penrose Diagram; Einstein universe; Newman-Penrose formalism; Sigma-process; Resolution of singularities; Maxwell s equations; Cylinder at spatial infinity; Rumslig oändlighet; Konform omskalning; Minkowski rummet; Penrose Diagram; Einsteins universum; Newman-Penrose formalismen; Sigma-processen; Singularitetupplösning; Maxwells ekvationer; Cylindern vid rumslig oändlighet;

    Abstract : The treatment of spatial infinity is one of the remaining major open problems in the theory of isolated self-gravitating systems. Especially when one wants to model scattering of gravitational radiation in spacetime. In this thesis the conformal theory is used to study simple electromagnetic fields, close to spatial infinity.

  5. 9. Theoretical Proof Of Concept For The Green Revolution Energy Converter : Development of a mathematical model, material analysis and physical model improvements

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Markus Eriksson; Oscar Magnusson; Lukas Haglund; John Malmdal; Gustav Edholm; [2022]
    Keywords : ;

    Abstract : The GREC is a new type of renewable heat engine that challenges the current dominating combustion engines. By using renewable energy the GREC offer a theoretical high efficiency, possibilities for large scalability and a high power output. READ MORE

  6. 10. A strategy for improving reliability in assembly processes

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Tommy Dahlström; [2021]
    Keywords : Assembly systems; Lean Six Sigma; Complexity;

    Abstract : This report presents an explorative examination of the scientific literature regarding current methods utilized in mixed-model assembly lines and the challenges that are faced. Empirical data from a real mixed-model assembly line was collected and analyzed to explore the application of the identified methods and the problems that are faced in a realistic situation. READ MORE
