1. 21. Validering av KFX för vätgasjetflammor som träffar ytor

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Jonathan Nilsson; [2024]
   Nyckelord :Kameleon FireEX; KFX; CFD; Hydrogen Jetfire; Technology and Engineering;

   Sammanfattning : Regarding climate change and the future need för renewable energy, hydrogen is considered to be an important component in energy storage systems. However, the use of hydrogen is fraught with risk due to its chemical properties. This thesis deals with the problem of modelling heat transfer from hydrogen jet flames hitting surfaces. LÄS MER

3. 22. Quantum Optical Description of High-order Harmonic Generation

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Isabel Moreno; [2024]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

4. 23. Data streaming provenance in advanced metering infrastructures

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Zozk Mohamed; [2023-11-24]
   Nyckelord :Advanced Metering Infrastructure; Ananke; Apache Flink; Göteborg Energi; Provenance; Stream processing; Stream Processing Engine;

   Sammanfattning : Increasing volumes of data in digital systems have made the traditional approach of gathering and storing all the data while analyzing it in bulks at periodic intervals challenging and costly. One such field is the electric grid market, which has started modernizing its aging grids into smart grids where Advanced Metering Infrastructures (AMIs) play a vital role. LÄS MER

5. 24. Audio Anomaly Detection in Cars

   Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

   Författare :Asma Hussein; [2023-09-11]
   Nyckelord :Audio Anomaly detection; Outlier detection; Machine learning; Mel Frequency; Chroma;

   Sammanfattning : Audio anomaly detection in the context of car driving is a crucial task for ensuring vehicle safety and identifying potential faults. This paper aims to investigate and compare different methods for unsupervised audio anomaly detection using a data set consisting of recorded audio data from fault injections and normal "no fault" driving.

7. 25. Powering Sustainable Development with SMRs - A qualitative study examining the potential effects of Small Modular Reactor deployment in Southern Sweden

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Alixander Kanaan; Marcus Magnusson; [2023-07-19]
   Nyckelord :Small modular reactors; Sustainability; Eco-Innovation;

   Sammanfattning : Europe has been immensely impacted by the recent turmoil in the continent and an energy crisis has emerged. Energy prices have soared over a period of two years and the price of energy is still at elevated levels throughout Europe and a high dependency on fossil fuels for energy production has become inevitable.
