1. 1. LEO Satellite Connectivity for flying vehicles

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

   Författare :Jinxuan Chen; [2023]
   Nyckelord :LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

   Sammanfattning : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

3. 2. DRY POWDER FOR INHALATION - INFLUENCE OF MIXING PROCESS AND ADDITION OF MAGNESIUM STEARATE

   Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Love Ivarsson; [2023]
   Nyckelord :inhalation; drug delivery; pulmonary drug delivery; API; FPF; FPD; DD; Turbula; Diosna; mixing energy; mixing time; mixing speed; pharmaceutical technology; Medicine and Health Sciences;

   Sammanfattning : For efficient treatment of many diseases of the lung, it is beneficial to deliver the medicine to the respiratory tract directly. This ensures a rapid response since it can enter the bloodstream directly through the alveolar epithelium. Consequently, also decreases systemic effects due to the local treatment. LÄS MER

4. 3. Lagen som ett retoriskt objekt - En analys av gamla och nya konsumentköplagen

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

   Författare :Lukas Rosén; [2023]
   Nyckelord :allmän rättslära; rättshistoria; rättsvetenskap; Perelman; Bitzer; konsumentköplagen; rättslingvistik; rättsretorik; Law and Political Science;

   Sammanfattning : Arbetet ämnar ge ett teoretiskt perspektiv på utformningen av det svenska lagspråket. Genom en retorisk argumentationsanalys, grundad i Chaïm Perelmans teori om föreställda publiker och Lloyd Bitzers teori om den retoriska situationen, utreds konsumentlagstiftningen i sin egenskap som meningsbärare mellan en retorisk avsändare och en retorisk mottagare.

5. 4. Suppression of Li-ion Battery Fires

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Linfan Cai; [2023]
   Nyckelord :Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

   Sammanfattning : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

7. 5. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Adam Jacobsson Trönndal; [2023]
   Nyckelord :Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

   Sammanfattning : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. LÄS MER
