  1. 6. Principal Component Analyses of Final States in Relativistic Nuclear Collisions using PYTHIA/Angantyr

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

    Författare :Nicoline Krogh Hemme; [2020]
    Nyckelord :Relativistic Nuclear Collisions; Heavy-ion Collisions; Pythia; Angantyr; String Shoving; Colour Reconnection; Principal Component Analysis; Anisotropic Flow; Elliptic Flow; Event-by-event Fluctuations; Physics and Astronomy;

    Sammanfattning : We develop a program to perform a principal component analysis of flow fluctuations using simulations of nuclear collisions produced by the PYTHIA/Angantyr event generator. We consider both p+p and p+Pb collision events and study the leading and subleading modes of the second flow harmonic. LÄS MER

  3. 7. Development and simulation of an active target detector with GEM foil readout

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Författare :Elisabeth Rickert; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : At CERN, radioactive ion beams with energies of up to 10 MeV/u can be pro- duced by a newly commissioned post-accelerator, HIE-ISOLDE, which expands the possibilities for nuclear reaction studies. To investigate the collision properties of the ion beam with a target, an active gas–target detector is under development by the Reactions Group at the Nuclear Physics Division in Lund. LÄS MER

  4. 8. Risk based monitoring in clinical studies – improving data quality

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Sara Ståhl Bengtsson; [2017]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Study quality is of paramount importance in clinical studies to ensure patient safety and reliable evaluation of the treatment, where the latter also entails the safety of future patients. Therefore, for example monitoring is required to minimise any risk of quality loss. LÄS MER

  5. 9. Comparative study of risk analysis methods from a fire safety perspective - Case study of new underground facilities at CERN

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Frida Olin; Erik Isaksson; [2016]
    Nyckelord :Risk analysis methods; design fires; event tree analysis; preliminary hazard analysis; What-if; ROGA; Gretener method; NFPA 101; comparative analysis; CERN; technical risk analysis methods; case study; LHC; HL-LHC; complex methods; simplified methods; Technology and Engineering;

    Sammanfattning : This report has investigated which type of risk analysis methods that can be used in an early design phase in a unique facility from a time and quality perspective. Two planned underground facilities for the HL-LHC at CERN have been used as a case study. LÄS MER

  7. 10. Parametrar för mikrosimulering av cykeltrafik Känslighetsanalys av cykelmodell i Vissim och kalibrering av hastighets- och accelerationsfördelning

    Master-uppsats, Lunds universitet/Trafik och väg

    Författare :David Palmqvist; [2015]
    Nyckelord :Mikrosimulering; Vissim; Cykeltrafik; Hastighet; Acceleration; Känslighetsanalys; Technology and Engineering;

    Sammanfattning : A semi-automatic way of calibrating micro-simulation models in Vissim with the elementary effects method is used on a traffic simulation over a mixed traffic crossing in Lund. The analysis is carried out by writing a script in Visual Basic connecting to Vissim via COM objects that iterates the elementary effects method over the whole range of suitable parameters. LÄS MER
