1. 21. Real time non-invasive estimation of oxygen uptake using smartphones

   Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

   Författare :Arvid Lund; [2023]
   Nyckelord :Oxygen uptake; Acceleration; Smartphone; Estimation; Health; Technology and Engineering;

   Sammanfattning : Oxygen uptake is a great indicator of cardiopulmonary health but requires spe- cialized equipment and is time consuming to measure. There are ways to estimate oxygen uptake based on other factors such as heart rate and acceleration. LÄS MER

3. 22. Exchange Rate Regimes and Trade in the Western Balkans

   Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

   Författare :Clara Falkenek; [2023]
   Nyckelord :Exchange Rate Regimes; Euro; Western Balkans; Gravity Model; Trade; Business and Economics;

   Sammanfattning : The choice of exchange rate regime is believed to affect countries’ trade levels. Currency unions and currency pegs reduce exchange rate volatility and create greater price transparency in foreign trade compared to a flexible exchange rate regime. LÄS MER

4. 23. Trajectory Optimisation of a Spacecraft Swarm Maximising Gravitational Signal

   Master-uppsats, KTH/Optimeringslära och systemteori

   Författare :Rasmus Maråk; [2023]
   Nyckelord :Spacecraft Swarms; Trajectory Optimisation; Impulsive Manoeuvres; Evolutionary Algorithms; Polyhedral Gravity Model; Small Body Exploration; Discrete Spherical Grids; Svärmande rymdfarkoster; Banoptimering; Impulsiva manövrar; Evolutionära Algoritmer; Polyhedral gravitationsmodell; Utforksning av små kroppar i solsystemet; Diskreta sfäriska rutnät;

   Sammanfattning : Proper modelling of the gravitational fields of irregularly shaped asteroids and comets is an essential yet challenging part of any spacecraft visit and flyby to these bodies. Accurate density representations provide crucial information for proximity missions, which rely heavily on it to design safe and efficient trajectories. LÄS MER

5. 24. Gravitational Decoherence in Macroscopic Quantum Systems

   Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Niklas Engelhardt Önne; [2023]
   Nyckelord :decoherence; gravitational decoherence; quantum mechanics; quantum physics; macroscopic quantum mechanics; macroscopic quantum physics; gravity; general relativity; gravitational time dilation; quantum-to-classical transition; nonrelativistic quantum mechanics; quantum gravity; dekoherens; gravitationell dekoherens; kvantmekanik; kvantfysik; makroskopisk kvantmekanik; makroskopisk kvantfysik; gravitation; allmän relativitetsteori; gravitationell tidsdilatation; övergången från kvantfysik till klassisk fysik; ickerelativistisk kvantmekanik; kvantgravitation;

   Sammanfattning : The problem of how quantum mechanics gives rise to classicality has been debated for more than a century. A commonly proposed solution is decoherence, i.e. the gradual decay of superpositions in open quantum systems due to their inevitable interaction with their environment. LÄS MER

7. 25. Digitalised Combats and Their Impact on Social Sustainability in Kenya and Nigeria

   Master-uppsats, Försvarshögskolan

   Författare :Roland Aszalós; [2023]
   Nyckelord :Africa; digitalisation; digital transformation; combats; social sustainability; terrorism; al-Shabaab; Boko Haram; peacekeeping; securitisation; Centre of Gravity; cyber warfare; cryptocurrency; dark web; social media;

   Sammanfattning : In our era, digital technology is one of the fastest-changing areas. It impacts our private life, well-being, economics, politics and warfare. This essay intends to answer how digital transformation affects combats and state and non-state actors and also how these digitalised combats compromise social sustainability. LÄS MER
