1. 1. Stability improvement to a ruthenium catalyst for partial oxidation of methane

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Melker Axelsson; [2023]
   Nyckelord :catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

   Sammanfattning : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. LÄS MER

3. 2. Improved Modelling For Oxidation Of Zircalloy Fuel Cladding Tubes In PWRs

   Master-uppsats, KTH/Fysik

   Författare :Rafaël Bellachia; [2023]
   Nyckelord :Nuclear Engineering; Corrosion; Zircalloy; PWR; Nuclear Fuel; Kärnteknik; Korrosion; Zircalloy; PWR; Kärnbränsle;

   Sammanfattning : The fuel cladding is an essential component in the defence-in-depth strategy for nuclear safety. Its integrity and durability are therefore critical for maintaining acceptable safety conditions. However, the integrity of the cladding can be compromised during normal operation due to corrosion and hydriding. LÄS MER

4. 3. Wildfire growth modelling in Sweden - a suitability assessment of available data

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Henrik Hagelin; [2023]
   Nyckelord :Geography; GIS; Geographic Information Science; Physical geography; Prometheus; WiSE-FASS; The 2014 Västmanland wildfire; Wildfire growth modelling; Wildfire suppression support; Wildfire behaviour; MESAN; Earth and Environmental Sciences;

   Sammanfattning : Wildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. LÄS MER

5. 4. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Colin Potter; [2023]
   Nyckelord :Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

   Sammanfattning : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

7. 5. Solving Ordinary Differential Equations and Systems using Neural Network Methods

   Kandidat-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

   Författare :Mimmi Westrin; [2023]
   Nyckelord :Neural network methods; trial solutions; numerical methods; Lotka-Volterra system; SEIR model;

   Sammanfattning : The applications of differential equations are many. However, many differential equations modelling real-world scenarios are very complex and it can be of great difficulty to find an exact solution if one even exists. Thus, it is of importance to be able to approximate solutions of differential equations. LÄS MER
