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

    Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

    Författare :Natasha Jamali; Hoda Kasem; [2023-06-28]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Eglantin Gjoni; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  4. 3. Patientsäkerhet i relation till sjuksköterskors arbetsbelastning : En litteraturöversikt

    Kandidat-uppsats, Marie Cederschiöld högskola/Institutionen för vårdvetenskap

    Författare :Ingrid Schwalbe; Jennifer Ekeberg; [2023]
    Nyckelord :Workload; Patient safety; Turbulence; Work enviroment; Stress; Nurses; Arbetsbelastning; Patientsäkerhet; Turbulens; Arbetsmiljö; Stress; Sjuksköterskor;

    Sammanfattning : Background The workload of nurses is a frequently discussed issue, the subject often concludes that it is unsustainable on both a national as well as an international level. The background explains the main focus of this litterature review, which is patient safety, which also is one of many of the nurses responsibility tasks. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

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

    Sammanfattning : 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.

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

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Alix Le Bastard; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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.
