1. 31. Hydrogen Fuel Cell Lifetime Simulation in Marine Applications

   Master-uppsats, KTH/Kraft- och värmeteknologi

   Författare :Yifeng Zhong; [2022]
   Nyckelord :maritime transportation; FEMFC; lifetime simulation; degradation mechanism; empirical relationship; semi-empirical approach; sjötransport; PEM-bränsleceller; livslängdssimulering; nedbrytningsmekanism; empiriskt samband; semi-empiriskt tillvägagångssätt;

   Sammanfattning : Maritime transportation emits about 3% of global greenhouse gas, International Maritime Organization (IMO) aims to reduce shipping’s emissions by 50% with respect to 2008 levels. Proton exchange membrane fuel cells (PEMFCs) are considered among the most promising clean technologies for decarbonizing the maritime sector. LÄS MER

3. 32. Methodology for Obtaining S-N Curves using Fatigue Testing and Static FEA

   Master-uppsats, Jönköping University/JTH, Material och tillverkning

   Författare :Filip Anderfelt; David Äse; [2022]
   Nyckelord :Fatigue; Testing; Fatigue Testing; Test rig; Pneumatic; FEA; Weld; Steel; Fillet Weld; S-N curve;

   Sammanfattning : The use of recommended S-N curves, presented in current literature, to analyse and determine the fatigue life of a part is common practice in, inter alia, the construction industry.However, the recommended S-N curves are generally created for larger components used in mainly the construction industry.

4. 33. Solceller på Västergårdsgymnasiet : En förstudie för att implementera solceller och energilagring ur ett ekonomiskt perspektiv

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

   Författare :Tim Gyulanszky; [2022]
   Nyckelord :solceller; energilagring; vätgas; litium-jon; flödesbatteri;

   Sammanfattning : The purpose of the project was to carry out a study of a potential solar cell facility at Västergårdsgymnasiet. Previous studies have established that there is the greatest potential for electricity production during the summer period, which coincides with the load at its lowest. LÄS MER

5. 34. Deployable Base Stations for Mission Critical Communications

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Gokul Panneerselvam; [2021]
   Nyckelord :UAVs; Load balancing; Wireless networks; Power control; Aerial base stations; 5G Radio; Drones; Genetic Algorithm; UAV: er; Lastbalansering; Trådlösa nätverk; Strömkontroll; Antennbasstationer; 5G -radio; Drönare; Genetisk Algoritm;

   Sammanfattning : Uninterrupted network connectivity is vital for real-time and mission-critical communication networks. The failure of Base Stations due to unforeseen circumstances such as natural disasters or emergencies can affect the coverage and capacity provided by terrestrial communication networks. LÄS MER

7. 35. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

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

   Författare :Mantas Petrosius; [2021]
   Nyckelord :;

   Sammanfattning : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.
