  1. 1. 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.

  3. 2. 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

  4. 3. 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

  5. 4. Vindkraftens påverkan på smålom

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Joel Hallingfors; Marcus Åsberg Genctürk; [2023]
    Nyckelord :smålom; vindkraftsetablering; skyddszon; buffertzoner; QGIS; habitatpåverkan;

    Sammanfattning : Vindkraftsetableringar i Sverige ökar och har ökat kraftigt de senaste åren. Etableringen leder till att olika intressen krockar med varandra och hänsyn måste tas till drabbade arter som exempelvis smålom (Gavia stellata). LÄS MER

  7. 5. Information requirements for future operators of autonomous drones at airports

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Jonathan Källbäcker; [2023]
    Nyckelord :Autonomous drones; airports; cognitive work analysis; thematic analysis; interface requirements; information requirements.;

    Sammanfattning : To gain an understanding about what information requirements there are for future operators of autonomous drone swarms at airport, this study examined how work at airports is structured today, what staff at airports think about the potential implementation of autonomous drones, and what potential interface components that are necessary to be able to control these drones. Interviews and observations were made at five different airports and air traffic control towers with tower and ground staff. LÄS MER
