   Författare :Signe Rirdance; [2023]
   Nyckelord :Language change; Latvian in Sweden; diaspora Latvian; heritage Latvian; family language policy; language maintenance; language attrition; heritage language acquisition; divergent attainment; Språkförändring; lettiska i Sverige; lettisk diaspora; lettiska arvsspråket; hemspråkspolicy; språkunderhåll; språkförlust; inlärning av arvsspråk; avvikande språkförmåga; Valodas pārmaiņas; latviešu valoda Zviedrijā; diasporas latviešu valoda; etniskā mantojuma valoda; ģimenes valodas politika; valodas uzturēšana; valodas zaudēšana; mantojuma valodas apguve; atšķirīga valodas apguve;

   Sammanfattning : Heritage languages are increasingly seen as a source of important insight in linguistics. Latvian has a long and under-researched history as a heritage language, with a heterogenous community of heritage speakers from two waves of migration in many countries including Sweden. LÄS MER

3. 2. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Fatiha El Azrak; [2023]
   Nyckelord :;

   Sammanfattning : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

4. 3. Risk of fragment hit on aircraft after releasing a bomb

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Hedberg Joakim; [2022]
   Nyckelord :Flightmechanics; probability; aerodynamics; Flygmekanik; sannolikhet; aerodynamik;

   Sammanfattning : An aircraft is exposed for a certain risk during warhead deployment. If the distance is too short between the aircraftand warhead during burst, fragments may hit the aircraft with fatal consequences. The warhead consists not onlyof fragments created during burst but also parts to attach it to the aircraft such as mounting plates and fasteningloops. LÄS MER

5. 4. The intraspecific drought tolerance of Betula pendula Roth. : ecotypic aptitude as tree selection criteria for the urban landscape

   Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

   Författare :Simon Hannus; [2021]
   Nyckelord :Betula pendula; clinal variation; drought tolerance; ecosystem services; ecotypes; potential evapotranspiration; turgor loss point; urban forestry; urban resilience; urban tree selection;

   Sammanfattning : The ecosystem services provided by urban trees are substantial contributors to the quality of urban living, and their environmentally regulating capabilities are increasingly regarded as integral in order to efficiently secure urban resilience, by ameliorating the human and material impacts of extreme weather events. However, current trends of urban development presents challenges of how to preserve urban greenery ecosystem functioning, particularly in light of the ongoing climate change; which also has brought forth the importance of taxonomically diverse urban forests, to mitigate risks of catastrophic tree loss associated with these conditions.

7. 5. Torque-Based Load Estimation for Passenger Vehicles

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Tobias Nyberg; [2021]
   Nyckelord :Load Estimation; RLS; Recursive least squares; torque; torque-based; mass estimation; mass; passenger vehicle; estimation algorithm; load estimation algorithm; forgetting factor; RLS with forgetting factor;

   Sammanfattning : An accurate estimate of the mass of a passenger vehicle is important for several safety systems and environmental aspects. In this thesis, an algorithm for estimating the mass of a passenger vehicle using the recursive least squares methodis presented. LÄS MER
