  1. 16. Evaluation of structurally controlled rockfall hazard for underground excavations in seismically active areas of the Kiirunavaara mine

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Manuel Alberto Fuentes Espinoza; [2023]
    Keywords : Structurally controlled rockfalls; rockfalls due to seismic shaking; sublevel caving; fork layout; Unwedge; wedge analysis; deterministic analysis; probabilistic analysis;

    Abstract : Sublevel caving operations at great depths are subjected both to large stress concentrations that are redistributed as the mining front progresses and to mining-induced seismicity. This is the case for Kiirunavaara mine, Sweden’s largest underground mine. READ MORE

  3. 17. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Simon Peter Dagbui; [2023]
    Keywords : Kiruna mining district; Common earth model; petrophysics; density; AMS; complex electrical resistivity; NRM; magnetization; IOA; Kirunavaara Mineralization;

    Abstract : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. READ MORE

  4. 18. Real time non-invasive estimation of oxygen uptake using smartphones

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

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

    Abstract : 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. READ MORE

  5. 19. Exchange Rate Regimes and Trade in the Western Balkans

    University essay from Lunds universitet/Nationalekonomiska institutionen

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

    Abstract : 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. READ MORE

  6. 20. Trajectory Optimisation of a Spacecraft Swarm Maximising Gravitational Signal

    University essay from KTH/Optimeringslära och systemteori

    Author : Rasmus Maråk; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE
