1. 1. The COVID-19 Pandemic’s Influence on Born-digitals’ Internationalization and Performance

   University essay from Göteborgs universitet/Företagsekonomiska institutionen

   Author : Natasha Jamali; Hoda Kasem; [2023-06-28]
   Keywords : ;

   Abstract : In this qualitative research, the purpose is to explore the influence of the COVID-19 pandemic on born-digital firms’ international expansions and performance. This is to fill in the gap in research where many other industries have been examined in relation to the pandemic but not the born-digital firms. READ MORE

3. 2. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications

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

   Author : Eglantin Gjoni; [2023]
   Keywords : ;

   Abstract : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. READ MORE

4. 3. Modeling of the trajectory of ice thrown from a wind turbine

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Elena Rocchi; [2023]
   Keywords : Ice thrown - Ice fall - RANS - LES - CFD - simulations - ballistic model; Technology and Engineering;

   Abstract : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

5. 4. Methods and Purposes of Aerodynamic Correlation in Formula Student

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Alix Le Bastard; [2023]
   Keywords : Technology and Engineering;

   Abstract : This thesis investigates how methods of aerodynamic validation can assist a formula student team in designing their aerodynamic package. When de- signing their aerodynamic components, formula student team mostly rely on CFD software simulations, but there is no guarantee that the simulations de- pict properly the physical behaviour of the airflow around the car.

6. 5. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Alazne Irene Varela Santana; [2023]
   Keywords : stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

   Abstract : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.
