1. Geometrical Improvement of Fuel Nozzle Locations in the SGT-750 Gas Turbine : An investigation into fuel-air mixing in main channels 1 & 2
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : This study was conducted on SGT-750, which utilizes can type fourth generation DLE burner, developed at Siemens Energy AB, in Finspång, Sweden. The aim of this study is to obtain a flat fuel profile at the outlet of main channel 1 and main channel 2, demonstrating a proper mixing of fuel and air in the main channels leading to reducing local high-temperature points, and thus, reducing thermal NOx emissions.

2. Bjälklagselement i håldäck och korslimmat trä : En jämförelsestudie mellan två bjälklagselement
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : I dagens samhälle ligger fokus på hållbarhet vilket ställer höga krav på konstruktören vid utformningav stommen till flerbostadshus. En stor del av CO2-utsläppen inom byggprocessen kan härledas tillmaterialvalet där förbränning av kalk inom cementindustrin och framställning av stål ur järnmalm ärbland de främsta faktorerna till utsläppen.

3. A Machine Learning Approach for Comprehending Cosmic Expansion
Master-uppsats, KTH/FysikSammanfattning : This thesis aims at using novel machine learning techniques to test the dynamics of the Universe via the cosmological redshift-distance test. Currently, one of the most outstanding questions in cosmology is the physical cause of the accelerating cosmic expansion observed with supernovae. LÄS MER
4. Phase control with spatial-light modulators towards application for opto-optical modulation
Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : This project is about focusing a Gaussian laser beam that has a spatial phase profile applied by a spatial light modulator. The goal is to be able to control the shape, position and phase of the peak at the focus and to split up the peak at the focus into several peaks. LÄS MER
5. Hybrid Vehicle Control Benchmark
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : The new emission regulations for new trucks was made to decrease the CO2 emissions by 30% from 2020 to 2030. One of the solutions is hybridizing the truck powertrain with 48V or 600V that can recover brake energy with electrical machines and batteries. The control of this hybrid powertrain is key to increase fuel efficiency. LÄS MER
