  1. 1. Design of cooling-air permeable coil support

    University essay from KTH/Hållfasthetslära

    Author : Rozbeh Ghassemi; [2023]
    Keywords : Topology optimization; FEM-simulations; CFD-simulations; Material selection; Topologioptimering; FEM-simuleringar; CFD-simuleringar; Materialval;

    Abstract : Coil supports are integral load-bearing components employed in generators andmotors. They serve the purpose of preventing excessive deformation and maintaininga stable position of the coils responsible for generating power and magnetic fieldswhen rotating. READ MORE

  3. 2. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project

    University essay from Uppsala universitet/Geofysik

    Author : Wanyi Li; [2022]
    Keywords : Scandinavian Caledonides; remanent magnetization; AF demagnetization; temperature dependent magnetic susceptibility; Skandinaviska Kaledoniderna; remanent magnetism; växelfältsavmagnetisering; temperaturberoende av magnetisk susceptibilitet;

    Abstract : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. READ MORE

  4. 3. Flotation of Yxsjöberg historical tungsten ore tailings

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Princess Rochelle Gan; [2019]
    Keywords : ;

    Abstract : Tailings dams, due to their sheer size and metal content, pose safety and environmental hazards. The Småltjarnen repository, which hosts material from the largest known tungsten mineralization in Sweden named the Yxsjöberg deposit, is estimated to contain 2. READ MORE

  5. 4. Test bench for Nanosatellite Attitude Determination and Control System (ADCS)devices : Design and manufacture of a Merritt Cage

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alvaro Cano Torres; [2019]
    Keywords : Helmholtz; Merri􀆩; Cage; Test; ADCS; Nanosatellite; Magne􀆟c; Orbit; Propaga􀆟on; Weightlessness; Air; Bearing.;

    Abstract : Attitude Determination and Control System (ADCS) is often a complex system on-board any  satellite  which  needs  validation  and  testing  to  prove  its  operability  and  verify  its software  compatibility  with  hardware  and  other  subsystems.    One  failure  in  orbit  is extremely expensive in terms of cost and time due to payload preparation and launch.

  6. 5. Characterizing magnetic susceptibility and remanent magnetization of magnetite and hematite rich drill-core samples at Blötberget

    University essay from Uppsala universitet/Geofysik

    Author : Andreas Bjork; [2018]
    Keywords : Verwey; Morin; Curie; Néel; magnetite; hematite; alteration; iron-ore; quality control; kappabridge; hysteresis; susceptibility; anisotropy; Verwey; Morin; Curie; Néel; magnetit; hematit; oxidation; järnmalm; kvalitetskontroll; kappabridge; hysteresis; susceptibilitet; anisotropi;

    Abstract : Laboratory magnetic measurements are used to develop a methodology to characterize the Kiruna-type Rare Earth Elements (REE) bearing apatite iron-oxide deposits at Blötberget in central Sweden. This high-grade ore deposit is known to have sharp boundaries between lens shaped main ore bodies of magnetite-rich ore, and a complex hematite-rich ore associated with pegmatites and skarn formation.
