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. Anomaly Detection in the EtherCAT Network of a Power Station : Improving a Graph Convolutional Neural Network Framework

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Niklas Barth; [2023]
   Keywords : Unsupervised Learning; Multivariate Time Series; Graph Convolutional Neural Networks; Anomaly Detection; Industrial Control System; EtherCAT; Power Station; Electricity Grid;

   Abstract : In this thesis, an anomaly detection framework is assessed and fine-tuned to detect and explain anomalies in a power station, where EtherCAT, an Industrial Control System, is employed for monitoring. The chosen framework is based on a previously published Graph Neural Network (GNN) model, utilizing attention mechanisms to capture complex relationships between diverse measurements within the EtherCAT system.

4. 3. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Wenhan Zhou; [2023]
   Keywords : Transuranus; AI; Nuclear Fuel Rods;

   Abstract : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. READ MORE

5. 4. The effect of disorder on the axial anomaly in a lattice model in 1 + 1 dimensions

   University essay from KTH/Fysik

   Author : Agnes Wattrang; [2023]
   Keywords : Axial anomaly; tight-binding model; semiclassical physics; correlated disorder.; Axial kiral anomali; tätbindningsmodell; semiklassisk fysik; korrelerad oordning;

   Abstract : This work investigates the effect of a disorder potential, that represents impurities/dislocations in the lattice, on the time-dependent signature of the axial anomaly in a one-band tight-binding model in one spatial dimension. The tight-binding model is solved numerically and the simulation results are compared with a semiclassical expression for the time-dependent axial density, n5(t), due to Nielsen and Ninomiya [1].

6. 5. A Holistic Framework for Analyzing the Reliability of IoT Devices

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Leonardo Manca; [2023]
   Keywords : Canvas Learning Management System; Docker containers; Performance tuning Performance tuning; Internet of Things IoT ; Reliability; Failure rate; Availability; Comprehensive framework; IoT architecture; Failure modes; Reliability Block Diagram RBD ; Prestandajustering; Sakernas internet IoT ; Tillförlitlighet; Felfrekvens; Tillgänglighet; Heltäckande ramverk; IoT-arkitektur; Felfunktioner; Till-förlitlighetsblockdiagram RBD Canvas Lärplattform; Dockerbehållare; Prestandajustering;

   Abstract : In the rapidly evolving landscape of the Internet of Things (IoT), ensuring consistency and reliability becomes a top priority for a seamless user experience. In many instances, reliability is assessed through Quality of Service (QoS) metrics, sidelining traditional reliability metrics that thrive on time-dependent failure rates. READ MORE
