1. 21. Electric Passenger Aviation in Sweden : An analysis from the perspective of the Swedish aviation industry

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Madeleine Cromnier; Erik Södergren; [2023]
   Keywords : electric aviation; Swedish aviation industry; socio-technical systems; socio- technical transitions; multi-level perspective.; elflyg; svensk flygindustri; socio-tekniska system; socio-tekniska omställningar; multi-level perspective;

   Abstract : Transitions to more sustainable technologies and processes are a largely discussed topic that concerns several, if not all, global industries. This thesis studies the novel technology of electric passenger aviation as a sustainable option in the aviation industry. READ MORE

3. 22. The effects of sector free allowances & emissions on stock returns : A study on firms which partake in the EU emissions trading system

   University essay from Linnéuniversitetet/Institutionen för nationalekonomi och statistik (NS)

   Author : Mario Milic; Noah Stjernberg; [2023]
   Keywords : Stock returns; EU ETS; CO2 Emissions; Financial performance; Free allowances;

   Abstract : This study aims to investigate whether sectorial free allowances and sector emissions have any effect on a firm's stock return under the newly introduced EU ETS (Emission trading system). In doing so, the data have been structured as panel data and are gathered for a sample period of 10 years measuring from 2012-2021, looking at 6 sectors (Aviation, Combustion of fuels, refining of mineral oil, production of cardboard/ paper, production of pig iron and steel and production of bulk chemicals).

4. 23. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Gusten Zandler Andersson; [2023]
   Keywords : Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

   Abstract : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. READ MORE

5. 24. Improving Visibility Forecasts in Denmark Using Machine Learning Post-processing

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : August Thomasson; [2023]
   Keywords : visibility forecast; fog; machine learning; numerical weather predicition; XGBoost; Random Forest; siktprognos; dimma; maskininlärning; numerisk vädermodell; XGBoost; Random Forest;

   Abstract : Accurate fog prediction is an important task facing forecast centers since low visibility can affect anthropogenic systems, such as aviation. Therefore, this study investigates the use of Machine Learning classification algorithms for post-processing the output of the Danish Meteorological Institute’s operational Numerical Weather Prediction (NWP) model to improve visibility prediction.
