1. 1. GDPR Compliance in EU-US Data Transfers - Examining the impact of the EU Commission’s 2023 adequacy decision on surveillance risks

   Kandidat-uppsats, Lunds universitet/Institutionen för handelsrätt

   Författare :Linda Kidwell; [2024]
   Nyckelord :General Data Protection Regulation; Adequacy Decision; EU Commission; Surveillance law; Third country data transfers; US intelligence agencies; Law and Political Science;

   Sammanfattning : International data transfers serve to support the global economy, facilitating international collaboration and economic expansion. However this increased productivity comes at a cost, namely amplified personal data privacy and security risks. LÄS MER

3. 2. Analysis of a shape morphing structural battery: manufacturing, analytical modeling and numerical simulation

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

   Författare :Alfredo Bici; [2023]
   Nyckelord :;

   Sammanfattning : A reduction in the global use of fossil fuels is necessary when striving for a more sustainable future. One key strategy in the transition from fossil fuels is electrification. This strategy is particularly prominent within the transport sector, where more efficient ways to store electric energy are being pursued. LÄS MER

4. 3. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

   Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Kreshnik Margaritari; [2023]
   Nyckelord :Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

   Sammanfattning : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

5. 4. What limits the luminosity of red supergiants?

   Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Eric Svensson; [2023]
   Nyckelord :Stellar evolution; Red supergiants; Red giants; Luminosity; Binary stars; Binary star systems; Binary star interactions; Binary stellar evolution; Humphreys-Davidson limit; Upper luminosity limit; BSE; Population synthesis; Simulations; M31; LMC; SMC; Metallicity; Mass transfer; Merging; Physics and Astronomy;

   Sammanfattning : The observed upper limit of the luminosity of red supergiants, often called the Humphreys-Davidson limit, has recently been shown to be independent of metallicity and to not be explainable by single star evolution – findings that both contradict established ideas of the origins of the limit. It is now known that the vast majority of stars with sufficient mass to possibly evolve into red supergiants above the limit interact with companion stars at some point during their lives. LÄS MER

7. 5. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

   Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

   Författare :Björn Arvidsson; [2023]
   Nyckelord :BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

   Sammanfattning : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.
