  1. 1. Fences are like Ghosts are like Monuments : ephemeral social agreements under the neoliberal rule

    Kandidat-uppsats, Umeå universitet/Institutionen för kultur- och medievetenskaper

    Författare :Herkules Jansson; [2024]
    Nyckelord :territoriality; nationalism; fencing; bordering; monumentality; nationalist symbolism; nation building myths; memory production; Berzelii park; Raoul Wallenberg; territorialitet; nationalism; staket; gränsdragning; monumentalitet; nationalistisk symbolism; nationsbyggande myter; minnesproduktion; Berzelii park; Raoul Wallenberg;

    Sammanfattning : This essay delves into the intricate dynamics of Berzelii Park, focusing on the interaction between the mesh fence constructed in 2016 and the Raoul Wallenberg monuments. It examines the fence as a nationalist monument, revealing its transformative impact on the communal space and highlighting its role in shaping memories, identity, and ideological conflicts within the urban landscape.

  3. 2. The visibility of stellar transients in the Galactic Centre

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Astrofysik

    Författare :Jonathan Ström; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. LÄS MER

  4. 3. Temporary Halting of Wind Turbine Rotors toMitigate Effects on Birds

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Ola Hedberg; [2024]
    Nyckelord :Bird; mitigation; effect; wind farm; turbine; wind power; halting; collision; risk; birds; power; generation;

    Sammanfattning : This study assesses the viability of temporarily halting wind turbine operations as amitigation measure to protect bird populations during migration periods. Conducted in thenorthern Baltic, it examines the migration patterns, timings, and altitudes of various birdspecies, aiming to identify the most critical times for implementing turbine stoppages.

  5. 4. Ensuring safe docking maneuvers on floating platform using Nonlinear Model Predictive Control (NMPC)

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Federico Gatti; [2024]
    Nyckelord :Robotics; Space Engineering; Docking Maneuvers; Floating Platforms; Nonlinear MPC; MPC; Barrier function; PWM;

    Sammanfattning : Docking maneuvers are a relevant part of the modern space mission, requiring precision and safety to ensure the success of the overall mission. This thesis proposes using a non-linear Model Predictive Control (MPC) as a controller with various constraints to ensure safe docking maneuvers for a satellite. LÄS MER

  7. 5. Flow of charged particles in Pb-Pb and pp collisions at the LHC

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

    Författare :Mohamed Berkat; [2024]
    Nyckelord :Quark Gluon Plasma; QGP; Quantum Chromodynamic; QCD; flow coefficients; Event Plane; Cumulants; ALICE; Physics and Astronomy;

    Sammanfattning : This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. LÄS MER
