  1. 1. Småstaters hotbalansering : En realistisk förklaring till Sveriges och Finlands alliansbeslut i två mellankrigstider.

    Master-uppsats, Försvarshögskolan

    Författare :Henrik Eriksson; [2023]
    Nyckelord :Allianser; Hotbalansering; Småstater; Realism; Walts; Snyder;

    Sammanfattning : The period 1991-2022 has great similarities with the period 1919-1939 as both periods are characterised by a gradual deterioration of international organisations and end with a systemic war. Why then have Sweden and Finland applied for NATO membership in the contemporary period when they remained military non-aligned in the previous period?This study develops Walt’s balance of threat theory, by operationalising Snyder’s cost-benefit analysis as intervening variables in a most different system design.

  3. 2. Determination of Proton Beam Waist Positions Using Beam Position Monitors

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Synkrotronljusfysik

    Författare :Gustav Gird Fahlström; [2022]
    Nyckelord :ESS; European Spallation Source; Proton beam; waist; BPM; Method; transverse; beam dynamics; beam physics; Lattice Error; Matrix formalism; Python; trajectory simulation; physics; Physics and Astronomy;

    Sammanfattning : In this work, we examine a novel method for the determination of proton beam waist locations using beam position monitors. Based on the lattice of the final transport line section of the European Spallation Source linac, a simplified version of the beam line composed of quadrupole magnets and correctors is constructed in Python using a matrix formalism.

  4. 3. EU som säkerhetsaktör i Sahel : Hur unionens strategiska kultur formar dess agerande i regionen

    Master-uppsats, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Författare :Robin Nilsson; [2021]
    Nyckelord :Sahel; EU; strategic culture; Mali; conflict; Sahel; EU; strategisk kultur; Mali; konflikt;

    Sammanfattning : This Master thesis aims to study how the EU’s strategic culture shapes the EU as a security actor in the Sahel. A region stricken with poverty and conflict with no end in sight in which the EU and European states are deeply involved. LÄS MER

  5. 4. A Tension between the Early and Late Universe: Could Our Underdense Cosmic Neighbourhood Provide an Explanation?

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Sveva Castello; [2021]
    Nyckelord :Cosmology; Hubble tension; local void;

    Sammanfattning : In recent years, the increasingly precise constraints on the value of the Hubble constant, H0, have highlighted a discrepancy between the results arising from early-time and late-time measurements. A potential solution to this so-called Hubble tension is the hypothesis that we reside in a cosmic void, i.e. LÄS MER

  7. 5. Spherically Symmetric Gravitational Collapse

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

    Författare :Lucas Bring; [2021]
    Nyckelord :gravitational collapse; gravitation; general relativity; black hole; Schwarzschild coordinates; Gullstrand-Painleve coordinates; Friedmann-Robertson-Walker metric; finite-time collapse; Physics and Astronomy;

    Sammanfattning : This thesis presents a derivation of the equation of motion of particles in a dust star, as it undergoes collapse. This is done by finding exact solutions to the Einstein field equations. We follow the original work by Oppenheimer and Snyder, starting from the general spherically symmetric metric in comoving coordinates. LÄS MER
