  1. 1. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli

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

    Author : Elina Fernö; [2023]
    Keywords : Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

    Abstract : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. READ MORE

  2. 2. Online System for OrienteeringResults : A portable solution for collecting, processing andtransmitting orienteering results in real-time

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mattias Kallhauge; Kjell Turesson; [2022]
    Keywords : Mechatronics; Orienteering; Raspberry Pi; Mobile Network; Mekatronik; Orientering; Raspberry Pi; Mobilt nätverk;

    Abstract : Today orienteering competitions use digital sensors to collect the punches from each runner. This is done by a chip that the runner carries and punches at each control where a sensor is placed. This data is then collected and processed by a computer program to calculate the results.

  3. 3. The Effects of Forewarning Video Game Players About the Difficulty Level : A Quantitative Study on the Feeling of Workload

    University essay from Södertörns högskola/Medieteknik

    Author : Sami Ouzaa; Daniel Ström; [2021]
    Keywords : forewarning; difficulty; workload; skill; challenges; settings; video games; förvarning; svårighetsgrad; arbetsbörda; skicklighet; utmaningar; inställningar; digitala spel;

    Abstract : This study examines the impact of forewarning video game players about the difficulty level. The intention behind this is to ascertain whether or not there are effects from doing so and to explore what kind of implications they might have. The data collection was achieved by allowing participants to play three consecutive levels in a video game. READ MORE

  5. 5. The impacts of series compensated EHV lines on distance protection, and a proposed new mitigation solution

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Syed Arif Ullah Shah; [2017]
    Keywords : Series compensation; metal oxide varistor; voltage inversion; current inversion; sub-synchronous oscillation; quadrilateral characteristic distance relay; digital high-pass filter; Seriekompensation; metalloxidvaristor; spänningsinversion; ströminversion; subsynkron oscillation; fyrsidig karakteristiskt distansrelä; digitalt högpassfilter;

    Abstract : Series compensation is extensively applied to the transmission lines to increase the power transfer capability of transmission lines, reduce transmission losses, improve voltage profiles, and improve power oscillation damping and transient stability of power systems. But it modifies the apparent impedance of the transmission lines during fault conditions and might cause the distance protection of transmission lines to encounter directional discrimination issues and reach problems.
