1. 1. Investigating the dynamics between the developing Nordic hydrogen market and the electricity system under uncertainty

   University essay from KTH/Energiteknik

   Author : Timon Renzelmann; [2024]
   Keywords : energy modelling; energy storage; global sensitivity analysis; hydrogen; Method of Morris; Nordics; OSeMOSYS; uncertainty analysis; energimodellering; energilagring; global känslighetsanalys; vätgas; Morris-metoden; Nordiska länder; OSeMOSYS; osäkerhetsanalys;

   Abstract : The potential of hydrogen as a clean energy carrier is hotly debated, but it promises to significantly contribute to a sustainable energy future. Hydrogen can replace fossil fuels in carbon-intensive industries, heavy transport and aviation, and support a renewable energysystem by acting as energy storage to balance intermittent supply.

3. 2. Monte Carlo analysis of BWR transients : A study on the Best Estimate Plus Uncertainty methodology within safety analyses at Forsmark 3

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Jonathan Eriksson; [2023]
   Keywords : BEPU; Wilks; Uncertainty analysis; BISON; Monte Carlo; BWR; Osäkerhetsanalys; transientanalys; Forsmark;

   Abstract : Transient analyses at Forsmark nuclear power plant are currently performed using realistic computer models in conjunction with conservative estimates of initial- and boundary conditions. This is known as the combined methodology. READ MORE

4. 3. Enhancing Simulated Sonar Images With CycleGAN for Deep Learning in Autonomous Underwater Vehicles

   University essay from KTH/Matematisk statistik

   Author : Aron Norén; [2021]
   Keywords : Deep Learning; Machine Learning; Sonar; Simulation; GAN; cycleGAN; YOLO-v4; Data Sparsity; Uncertainty Estimations; Djupinlärning; maskininlärning; sonar; simulering; GAN; cycleGAN; YOLO-v4; gles data; osäkerhetsanalys;

   Abstract : This thesis addresses the issues of data sparsity in the sonar domain. A data pipeline is set up to generate and enhance sonar data. The possibilities and limitations of using cycleGAN as a tool to enhance simulated sonar images for the purpose of training neural networks for detection and classification is studied. READ MORE

5. 4. Robust Booster Landing Guidance/Control

   University essay from KTH/Optimeringslära och systemteori

   Author : Ugurcan Çelik; [2020]
   Keywords : Booster; Rocket; Reusable; Stage; Vertical; Landing; Auto-Pilot; Guidance; Control; Navigation; Reinforcement Learning; Robust; Optimization; Optimal Control; Uncertainty Analysis; Booster; raket; återanvändbar; scen; vertikal; landning; autopilot; ledning; kontroll; navigering; förstärkningsinlärning; robust; optimering; optimal kontroll; osäkerhetsanalys;

   Abstract : The space industry and the technological developments regarding space exploration hasn’t been this popular since the first moon landing. The privatization of space exploration and the vertical landing rockets made rocket science mainstream again. READ MORE

6. 5. Analysis of uncertainties in fatigue load assessment : a study on one Kaplan hydro turbine during start operation

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Annica Gustafsson; [2019]
   Keywords : Hydropower; Hydro turbine runner; Uncertainty analysis; Fatigue load; Fatigue damage; Propagation of uncertainty.; Vattenkraft; Löphjul; Osäkerhetsanalys; Utmattning; Delskada; Fortplantning av osäkeheter.;

   Abstract : In the future, hydropower plants are expected to operate more flexibly. This will lead to a more varied operation of the turbine and the generator, such as more start and stop in order to stabilise the frequency in the grid. Studies show that these transient operations are more costly in terms of fatigue degradation, i.e. READ MORE
