  1. 6. Development of an electric driveline model for multiscale road-cargo simulations

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Runzhe Wu; [2022]
    Nyckelord :System Engineering; AnyLogic Traffic Simulation; Simulink Simulation; Driveline Model Building; C Program Execution; Systemteknik; AnyLogic Trafiksimulering; Simulink Simulering; Drivelinemodell; C Programexekvering;

    Sammanfattning : Currently, the road cargo system with low or zero CO2 emission is under rapid development. Heavy-duty trucks with electrified driveline systems will be the workhorse of future freight. LÄS MER

  3. 7. Elbussar i Örnsköldsvik : En analys över vad som krävs för att elektrifiera bussarna i tätortstrafiken i Örnsköldsvik.

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Max Abrahamsson; [2022]
    Nyckelord :Buss; elbuss; kollektivtrafik; infrastruktur;

    Sammanfattning : For Sweden to achieve its environmental goals by 2045, municipalities need to reducegreenhouse gas emissions, especially from from the transport sector. Recentmeasurements in Örnsköldsvik have shown poor quality air in the built-up environment.Buses are the vehicle classes that emit, proportionally the most carbon dioxide equivalentgases. LÄS MER

  4. 8. Matter-streams as sources of the Kerr metric

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Julian Boy; [2022]
    Nyckelord :General Relativity; Black holes; Physics; Kerr metric; Physics and Astronomy;

    Sammanfattning : An introduction to the thin-shell formalism and distributional approach to General Relativity is provided. The formalism is utilized to investigate possible distributions of matter that can act as a source to the Kerr metric. LÄS MER

  5. 9. Projections for charm balance functions in heavy-ion collisions

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Tilde Bonnevier Wallstedt; [2022]
    Nyckelord :Heavy-ion physics; quark-gluon plasma; QGP; balance function; charm quark; Physics and Astronomy;

    Sammanfattning : In this thesis, pp collisions were simulated using PYTHIA. D+ D- and D0 D0bar balance functions were created in order to contribute with a reference point for future balance functions measured in real data from Pb-Pb collisions. LÄS MER

  7. 10. Understanding Rt using two-particle correlations by simulating proton-proton collisions in a Monte-Carlo model

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Johan Leygonie; [2021]
    Nyckelord :QGP; Quark-Gluon-Plasma; Rt; Particle Physics; Proton-proton Collisions; Pythia; Monte-Carlo Model; Bachelor s Thesis; Heavy-ion Collisions; ALICE; CERN; Relative Transverse Activity; Jets; Two-Particles Correlations; Quantum Physics; Physics and Astronomy;

    Sammanfattning : The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. LÄS MER
