1. 1. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Wenhan Zhou; [2023]
   Nyckelord :Transuranus; AI; Nuclear Fuel Rods;

   Sammanfattning : 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. LÄS MER

3. 2. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate

   Master-uppsats, KTH/Teknisk mekanik

   Författare :Joseph Vernier; [2023]
   Nyckelord :Computational Fluid Dynamics; Fluid Mechanics; Numerics; Micro-climate modeling; Radiation; Crop modeling; Photovoltaic panels;

   Sammanfattning : The increasing demand for energy, depletion of fossil fuels, rising global warming, and greenhouse gas emissions have stimulated the need for widespread development and adoption of renewable energy sources (RES) worldwide. Among these sources, solar energy has emerged as a major contender to meet the growing demand. LÄS MER

4. 3. Fouling modelling in a UHT unit based on plant data.

   Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Thai Lam; [2023]
   Nyckelord :UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

   Sammanfattning : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. LÄS MER

5. 4. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

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

   Författare :Carl Holmquist; [2023]
   Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

   Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

7. 5. Hardware in Loop Simulations of Electric Drives

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Varad Deshpante; [2023]
   Nyckelord :Electric Machines; Electronic Control Unit; Inverter; Field Programmable Gate Array; Hardware in the Loop; Software in the Loop; Elektriska Maskiner; Elektronisk Styrenhet; Växelriktare; Programmerbar Integrerad Krets; Hårdvara i Loop; Programvara i Loop;

   Sammanfattning : Electric drives are crucial components of powertrain of modern vehicles. They need to be controlled effectively to deliver a comfortable and efficient driving experience. The control unit needs to be robust to handle extreme operating conditions and faults in a safe manner. LÄS MER
